OMNI-BEAM Overview
Modular Design
OMNI-BEAM is a modular self-contained sensor. It is made up of a sensor head and a
power block; an optional plug-in timing logic module may be added easily. The three
modular components, sold separately, simply plug and bolt together — without
interwiring — to create a complete self-contained photoelectric sensor tailored to a
particular application’s exact sensing requirements.

OMNI-BEAM Sensor Heads
Sensor Heads
A sensor head module is available for every sensing situation. Sensor heads bolt
directly onto the power block, and are fully gasketed for protection against
environmental elements. The D.A.T.A. self-diagnostic feature is standard on all OMNIBEAM sensor heads (except emitters and model OSBFAC). Select from most sensing
modes, with infrared or visible red, green or blue sensing beams available.

Optional Timing Logic Modules
Timing logic may be added at any time, using one of three timing delay and pulse
logic modules. Installation is simple and quick; the logic modules simply slide into the
sensor head (see Figure 4). Program them for timing functions and ranges via four
DIP switches; each module includes easily accessible 15-turn clutched potentiometers
for accurate timing adjustments.

OMNI-BEAM Sensor Heads
Sensor Head Programming
DIP Switch Settings
OMNI-BEAM sensor heads are field-programmable for four operating parameters. To
access the four programming DIP switches (see figure 5), remove the sensor block
from the power block.
Switch #1, Sensing Hysteresis
ON: Standard hysteresis.
OFF: Low hysteresis; should be used only when all sensing conditions remain
completely stable.
Hysteresis is an electronic sensor requirement that the amount of received light
needed to energize the sensor’s output not be equal to the amount needed to release
the output. This differential prevents the sensing output from “buzzing” or
“chattering” when the received light signal is at or near the sensing threshold level.
The standard setting should be used always, except for low-contrast applications
such as the detection of subtle differences in reflectivity.
Switch #2, Alarm Output Configuration
ON: Alarm output is normally open (it conducts with an alarm).
OFF: Alarm output is normally closed (the output opens during an alarm).
Normally closed mode (OFF) is recommended; it allows a system controller to
recognize a sensor power loss or an open sensor output as an alarm condition.
Normally open alarm mode (ON) should be used when the alarm outputs of multiple
OMNI-BEAMs are wired in parallel to a common alarm or alarm input.
Switch #3, Light or Dark Operate
ON: Dark Operate mode; the output energizes (after a time delay, if applicable) when
the received light level is less than the sensing threshold (4 or fewer D.A.T.A.
lights ON).
OFF: Light Operate mode; the sensor’s load output energizes (after a time delay, if
applicable) when the received light level is greater than the sensing threshold (5
or more D.A.T.A. lights ON).

This switch should always be OFF, except for close differential sensing situations (for
example, some color registration applications, which also require the Low hysteresis
setting/switch #1 OFF).

OMNI-BEAM Sensor Heads
Using the D.A.T.A. Sensor Self-Diagnostic Feature
Banner’s exclusive D.A.T.A. feature warns of marginal sensing conditions, usually
before a sensing failure occurs, by flashing one or more lights in its multiple-LED
array, and by sending a warning signal to the system logic controller (or directly to an
audible or visual alarm). The chart below describes the meanings of the possible
signals.
Figure 6. OMNI-BEAM D.A.T.A. LEDs
Flashing LED
Problem
Description
#1
Moisture Alert
Severe moisture is inside the sensor head, caused by condensation or by entry of moisture when the
access cover is removed.
#2
High Temperature
Alert
The temperature inside the sensor head exceeds +70°C (+158°F).
#3
Low Voltage
or
Overload Alert
Sensor supply voltage is below the minimum specified for the power block in use. Power block outputs
also shut down to prevent damage to the load(s) from low voltage.
DC power blocks OPBT2, OPBT2QD, or OPBT2QDH: Either the load output or the alarm output is
shorted. Both outputs will be inhibited, and the circuit will “retry” the outputs every 1/10 second. The
outputs automatically reset and function normally when the short is corrected.
High Gain
Warning
The “dark” signal never goes below #4 on the display; decrease the Gain setting. There are two possible
causes:
1) The “dark” signal slowly increases and remains at the #4 level for a predetermined delay time,
commonly caused by a gradual increase of unwanted background reflections in reflective sensing
modes (such as diffuse or convergent). The alarm will reset as soon as the cause of the unwanted
light signal is removed, or if the Gain control setting is reduced to bring the “dark” condition below
the #4 level.
2) The “dark” signal does not fall below the #4 level during a sensing event. The alarm automatically
resets when the “dark” sensing level falls below the #4 level (accomplished by reducing the Gain
control setting and/or by removing the cause of unwanted light return in the “dark” condition).
Low Gain Warning
The “light” signal never goes above #5 on the display; increase the Gain setting. There are two possible
causes:
1) The “light” signal slowly decreases to the #5 level and remains at that level for a predetermined
delay. This most commonly occurs in opposed or retroreflective sensing systems, caused by a
gradual decrease in light in the unblocked condition, due to obscured lenses or sensor
misalignment. The alarm will reset when the light signal strength exceeds the #5 level.
2) The “light” signal does not exceed the #5 level during a sensing event. The alarm automatically
resets when the “light” signal exceeds the #5 level (accomplished by increasing the GAIN control
setting and/or cleaning the lens and realigning the sensor).
Low Contrast
Warning
The lights flash simultaneously to indicate inadequate optical contrast for reliable sensing (the “light”
condition is at the #5 level and the “dark” condition is at the #4 level). If this occurs, re-evaluate the
application to find ways to increase the differential between the “light” and “dark” conditions. The alarm
automatically resets when the “light” signal exceeds the #5 level and the “dark” signal falls below the #4
level.

OMNI-BEAM Sensor Heads
Sense and Load LED Indicators
The Sense LED indicates when a target has been sensed. When the sensor head is
programmed for Light Operate, it lights when the received light signal exceeds the #5
threshold. When programmed for Dark Operate, it lights when the received light
signal falls below the #5 threshold. See figure 7.
The Load indicator LED lights whenever the output is energized (after the timing
function, if applicable).
Measuring Excess Gain
Figure 7. Sense and Load indicators
OMNI-BEAM’s D.A.T.A. indicator display may be used to measure the excess gain and
contrast during sensing, installation, or maintenance.
Excess gain is a measurement of the amount of light energy falling on a photoelectric
sensor’s receiver, over and above the minimum amount needed to operate the
sensor’s amplifier. Excess gain is expressed as a ratio:
Excess gain (E.G.) = light energy falling on receiver
amplifier threshold
The amplifier threshold is the point at which the sensor’s output switches
(corresponding to the #5 level of the D.A.T.A. display). When LEDs #1 through #5 are
ON, the excess gain of the received light signal is equal to “1x.” The chart below
shows how excess gain relates to the D.A.T.A. light array indication.

OMNI-BEAM Sensor Heads
Measuring Sensing Contrast
Contrast is the ratio of the amount of light falling on the receiver in the “light” state,
compared to the “dark” state (sometimes called “light-to-dark ratio”). Optimizing the
contrast in any sensing situation increases the sensing reliability. Contrast may be
calculated if excess gain values are known for both the light and dark conditions:
Contrast = Excess gain (light condition)
Excess gain (dark condition)
Figure 8. Dark condition example:
D.A.T.A. system LEDs #1
and #2 lit.
To determine the contrast for any sensing application, present both the Light and Dark
conditions to the OMNI-BEAM, and note how many LEDs in the D.A.T.A. display are
ON for each condition. Compute the ratio from the corresponding excess gain
numbers (from the chart on page 6) for the two conditions.
For example, if LEDs #1 through #8 come ON in the Light condition and LEDs #1 and
#2 come ON in the Dark condition (assuming Standard scale factor), contrast is
calculated as follows:
Light condition: 2.2x excess gain
Dark condition: 0.35x excess gain
Contrast = 2.2x = 6
0.35x
This value is expressed as 6:1 (“six-to-one”).
The best sensor adjustment will cause all ten D.A.T.A. LEDs to come ON for the Light
condition, and none in the Dark condition. In this situation (such as an application in
which a box breaks the beam of an opposed-mode emitter/receiver pair):
Figure 9. Light condition example:
D.A.T.A. system LEDs
#1 through #8 lit.
Contrast is greater than
3.7x = 15
0.25x
While it is not always possible to adjust a sensor to maintain this much contrast, it is
important to always adjust for the maximum possible contrast. The D.A.T.A. feature
makes this easy. The chart below gives general guidelines for contrast values.
Contrast Values and Corresponding Guidelines
Contrast
Recommendation
1.2 or Less
Unreliable. Evaluate alternative sensing schemes.
1.2 to 2
Poor Contrast. Use the LOW hysteresis setting and the FINE
scale factor.
2 to 3
Low Contrast. Sensing environment must remain perfectly clean and
all other sensing variables must remain stable.
3 to 10
Good Contrast. Minor sensing system variables will not affect
sensing reliabilty.
10 or Greater
Excellent Contrast. Sensing should remain reliable as long as the
sensing system has enough excess gain for operation.

OMNI-BEAM E Series sensors feature electromechanical relay
output, all sensing modes, optional timing logic, and the choice of
pre-wired cable or quick-disconnect (shown) cable styles.
DESCRIPTION
SPECIFICATIONS
Banner E Series OMNI-BEAM™ sensors are a line of modular, selfcontained photoelectric sensors designed for applications where economy and performance are important. E Series OMNI-BEAMs have
SPDT (single-pole double-throw, form "C") electromechanical relay
output and employ a power block that operates from either 24 to 250V
ac or 24 to 36V dc. Sensing ranges of E Series OMNI-BEAMs are in
most cases identical to those of standard model OMNI-BEAMs.
SUPPLY VOLTAGE:
24 to 250V ac (50-60Hz), or 24 to 36V dc at 45mA dc maximum,
exclusive of load. DC hookup is without regard to polarity.
E Series OMNI-BEAM sensors are modular self-contained sensors
consisting of two major modules: a sensor head and a power block. Eseries sensors are available for all sensing modes. (NOTE: sensor
heads are interchangeable and are ordered individually.) LIGHT or
DARK operate output is selected via an easily-accessible internal
switch.
LED indicators for SENSE and LOAD are located atop the sensor head
beneath a transparent gasketed LEXAN® cover. Optional logic
module boards (page 6) slip easily into the sensor head and provide
adjustable delay or adjustable pulse timer logic. The SENSE indicator
lights whenever an object is sensed. The LOAD indicator lights
whenever the sensor's output relay is energized. This indicator is
especially useful when a timing logic module is used and SENSE and
LOAD conditions are not concurrent.
Their cross-hole mounting design with standard limit-switch hole
spacing enables OMNI-BEAM E Series sensors to be mounted from
the front, either side, or the back, making them ideal for conveyor and
other production line applications. E Series OMNI-BEAMs may also
be mounted using their 30mm threaded base mounting hub. A
versatile 2-axis stainless steel accessory mounting bracket (model
SMB30MM) and a VALOX ® swivel-mount bracket (model
SMB30SM) are available.
E Series opposed mode emitters use an emitter power block, either
model OPEJE or OPEJEQD. All other E Series sensors use either
model OPEJ5 or OPEJ5QD*. Models OPEJE and OPEJ5 have a 1/
2" NPS integral internal conduit thread and are supplied with a 6-foot
PVC-covered cable. Models OPEJEQD and OPEJ5QD ("QD"
models) have NEMA 4-rated quick-disconnect minifast™ connectors.
All models are housed in tough, molded VALOX® housings. The
electronics of E Series power blocks are epoxy-encapsulated. When
assembled, all parts of E Series OMNI-BEAMs are fully gasketed.
*NOTE: E Series sensor heads may also be used with Standard OMNI-BEAM
power blocks with solid-state output relay.
Printed in USA
OUTPUT CONFIGURATION:
one internal form "C" (single-pole double-throw) relay.
OUTPUT RATING:
Maximum switching power (resistive load) = 150W, 600VA.
Maximum switching voltage (resistive load) = 250V ac or 30V dc.
Maximum switching current (resistive load) = 5A.
Minimum voltage and current = 5V dc, 0.1A.
Mechanical life of relay = 10,000,000 operations.
Electrical life of relay at full resistive load = 100,000 operations.
RESPONSE TIME:
20 milliseconds ON and OFF. 100-millisecond delay on power-up
(relay is de-energized during this period).
TIMING LOGIC:
Optional logic modules are available (see page 6):
timing logic module OLM5 (DELAY timing logic)
timing logic module OLM8 or OLM8M1 (PULSE timing logic)
CONSTRUCTION: molded VALOX® thermoplastic polyester
housing. Power block is totally encapsulated. Molded acrylic lenses,
stainless steel hardware. When assembled, all parts are fully
gasketed.
Assembled E Series OMNI-BEAM Sensors are rated NEMA 1, 2, 3,
3S, 4, 12, and 13.
CABLE: sensors may be supplied either with 2-wire (for emitter
models) and 5-wire (for all other models) 6-foot long PVC-covered
cable and 1/2" NPS integral internal conduit thread in the sensor base,
or integral "QD" (Quick Disconnect) connector. "QD" models use 5conductor cable MBCC-512 (cable is sold separately, see page 2).
ADJUSTMENTS: multi-turn GAIN control on top of sensor (beneath a transparent gasketed LEXAN® cover) allows precise sensitivity setting (turn clockwise to increase gain). Internal switch selects
LIGHT operate or DARK operate. Optional logic module models
OLM5, OLM8, and OLM8M1 have adjustable timing functions (see
page 6).
INDICATOR LEDs: red LED indicators for SENSE and LOAD on
top of sensor (beneath a transparent gasketed LEXAN® cover).
SENSE LED lights whenever an object is sensed. LOAD LED lights
whenever output relay is energized.
OPERATING TEMPERATURE RANGE:
0 to +50 degrees C (+32 to +122 degrees F).

transparent cover from the top of the sensor head, then unscrew the four
captive assembly bolts that
hold the sensor head to the
LIGHT/DARK switch
power block. The switch is
L/O
D/O
easily operated with a small
screwdriver. Move the
switch to the LEFT for
LIGHT operate, or to the
RIGHT for DARK operate
(switch position information
is inscribed on the printed
circuit board, next to the
switch).
In LIGHT operate, the output is energized when the
sensor "sees" light. In
DARK operate, the output is energized when the sensor "sees" dark.

LONG-RANGE DIFFUSE (PROXIMITY) Mode
Diffuse (proximity) mode sensors detect objects by sensing their own emitted light reflected from the object. They are ideal for use
when the reflectivity and profile of the object to
be detected are sufficient to return a large percentage of emitted light back to the sensor.
Model OSEDX is the first choice for diffuse
(proximity) mode applications when there are
no background objects to falsely return light.

Model OSEFX is an excellent choice for glass
fiber optic applications compatible with the use
of an infrared sensing beam, and where faster
sensor response is not important. Excess gain is Diffuse Mode
the highest available in the photoelectric industry. As a result, opposed individual fibers operate reliably in many very hostile environments.
Also, special miniature bifurcated fiber optic
assemblies with bundle sizes as small as .020
inch (.5mm) in diameter may be used successfully for diffuse mode sensing.
The excess gain curves and beam patterns illustrate response with standard
.060 inch (1.5mm) diameter and .12 inch (3mm) diameter bundles. Response
for smaller or larger bundle sizes may be interpolated.

(Relay common)
Power block modules OPEJ5(QD) and OPEJE(QD) use "partial phase firing"
power conversion to enable their wide range of ac input voltage (24 to 250V
ac). AC power is applied to the sensor for only a small portion of each ac halfcycle. The current demand during this period may be as high as 1 to 2 amps
per sensor.
The collective current demand of several of these sensors on a common ac line
is significant. If several sensors are wired directly to the ac mains, it is
unlikely that any adverse effects will be noticed. On the other hand, problems
may be noticed if several sensors are connected to a common circuit that is
isolated from the ac mains by a transformer. The collective peak current
demand may rob other components on the same circuit of enough power to
function properly. In the worst case, a transformer with inadequate reserve
current capacity may overheat. Barring a transformer failure, the sensors
themselves will operate normally.
NOTE: Peak power demand is not an issue when these power blocks are
powered from direct current (24 to 36V dc).
NOTE: E Series OMNI-BEAM sensor heads may be also used with standard OMNI-BEAM power blocks with solid-state output relay.
When E Series sensor heads are used with these power blocks, the power block ALARM output functions as a second load output that switches
in parallel with the LOAD output (DPST). If the power block is a dc power block, neither output will have short-circuit or overload protection.
Also, E Series sensor heads do not have a D.A.T.A.™ display.

OMNI-BEAM Logic Modules
E Series OMNI-BEAM sensors easily accept the addition of timing logic when needed.
Three multiple-function logic modules are available (see photo, upper right). Model OLM5
is programmable for ON-delay, OFF-delay, or ON/OFF-delay timing logic. Models OLM8
and OLM8M1 offer either ONE-SHOT or DELAYED ONE-SHOT functions. Programming of the logic function, the timing range, and the output state is done via a set of four
switches located on the logic module.
Both logic modules feature 15-turn clutched potentiometers for accurate timing adjustments. The logic module simply slides into the sensor head housing and interconnects
without wires (see photo, lower right). Timing adjustments are easily accessible at the top
of the sensor head, and are protected by the sensor head's transparent, gasketed LEXAN®
cover. Assembled sensors are rated NEMA 1, 2, 3, 3S, 4, 12, and 13.
Plug-in timing logic modules are available for
either delay or pulse timing functions.
OMNI-BEAM Logic Module Specifications
Operating Temperature: -40 to +70°C (-40 to +158°F)
Timing Adjustments: Two 15-turn clutched potentiometers with brass elements, accessible
from outside at top of sensor block, beneath gasketed cover.
Timing Repeatability: Plus or minus 2% of timing range (maximum). Assumes conditions
Slide in
of constant temperature and power supply.
Useful Time Range: Useful range is from maximum time down to 10% of maximum all
models. When timing potentiometer is set fully counterclockwise, time will be approximately
1% of maximum for models OLM5 and OLM8, and 2% of maximum for model OLM8M1.
Response Time: A disabled timing function adds no measurable sensing response time.
OLM5 Delay Timer Logic Module
Model OLM5 is programmable for ON-DELAY or OFFDELAY or ON/OFF DELAY timing functions. Each
delay function may be independently adjusted and separately programmed for either a long or short adjustment
range.
The logic module slides into the sensor head
and interconnects without wires.

OMNI-BEAM
Model OSBFAC
AC-coupled
Fiber Optic Sensor Head
•
•
Highly sensitive to very small signal changes
•
Ideal for low contrast applications such as web flaw
and thread break detection, falling parts detection
•
Selectable light-operate or dark-operate; no false
pulse on power-up
•
Use with standard OMNI-BEAM ac or dc power
blocks and model OLM8 logic module
Automatic Gain Control circuit continually adjusts
emitter light output to maintain system gain
The OMNI-BEAM™ model OSBFAC is a special-purpose ac-coupled
fiber optic sensor head module. It is intended for applications in which
the light signal change is so small that sensitivity adjustment of ordinary
dc-coupled sensors is difficult or impossible. The OSBFAC responds to
even smaller signal changes than do standard fiber optic OMNI-BEAM
sensors set for LOW hysteresis, and is less affected by gradual signal
changes due to dirt buildup, etc. Typical applications include thread
break detection, web flaw detection, and detection of small parts falling
randomly from vibratory feeders or small presses.
Many such low-contrast photoelectric sensing applications present problems to dc-coupled sensors because of switching hysteresis. Switching
hysteresis is a designed-in property of dc-coupled sensors that causes the
"turn-on" point of the sensor's dc-coupled amplifier to be slightly different than the "turn-off" point. Its purpose is to prevent "indecision" and
erratic operation of the sensor's output circuit when the light signal is at
or near the switching point of the dc-coupled amplifier.
The OSBFAC, with its ac-coupled amplifier, reliably amplifies the small
signal changes found in many low-contrast sensing applications. An
automatic gain control (AGC) feedback system locks onto the light signal
and continually adjusts the light intensity of the emitter so that the system
is always maintained at exactly the desired reference level regardless of
the sensing range or degree of environmental contamination. A multiturn GAIN control enables setting of the amplifier sensitivity.
Instead of the D.A.T.A.™ array of other OSB Series sensor heads, the
OSBFAC has a LOCK indicator LED that lights when the AGC circuit
has locked onto the signal, and a LOAD indicator LED that lights
whenever the sensor's output circuit is energized. Both LEDs are easily
visible beneath the OSBFAC's transparent LEXAN® top cover.
A slide switch inside the base of the OSBFAC sensor head selects either
light- or dark-operate. When light operate is selected, output occurs on
a dark-to-light transition. When dark-operate is selected, output occurs
on a light-to-dark transition. The OSBFAC requires use of the model
OLM8 or OLM8M1 slide-in logic module. Sensor head output is in the
form of a quick pulse, and an OLM8 Series module is used to condition
this pulse to the desired length. See data sheet P/N 03522 or 03533 or the
Banner product catalog for further information on these logic modules.
The OSBFAC ac-coupled fiber optic sensor head may be used with any

sensor beneath a transparent LEXAN® window.
Indicators: LOCK LED lights whenever the AGC system has
locked onto a signal. LOAD LED lights whenever the sensor's output
circuit is energized. Both indicators located on top of the sensor
beneath a transparent LEXAN® window.
Operating Temperature Range: -40 to +70°C (-40 to +158°F)
Construction: housing is molded from rugged VALOX® thermoplastic polyester for outstanding electrical and mechanical performance in demanding applications. The top window is of transparent
LEXAN® polycarbonate. Hardware is stainless steel. When assembled to a compatible power block module, all parts are fully
gasketed.
Installation and adjustment
1) The OSBFAC requires the use of an OLM8 Series slide-in logic
module. Refer to the data sheet packed with the logic module. Program
the OLM8's DIP switches for the required pulse type and duration range,
then slide the OLM8 into the slot in the sensor head. Set the OSBFAC
sensor head for either light- or dark-operate, using the slide switch on
the underside of the sensor head (see bottom photo, right).
*Standard ac power block is .88" taller in height; overall height
of OSBFAC sensor head with an ac power block attached is 3.88".
2) Detach the clear LEXAN® top window from the OSBFAC by removing the single hold-down screw.
Assemble the OSBFAC head to the power block module using the four captive screws at the corners of the
module. Mount the sensor assembly at a convenient location (Banner mounting bracket model SMB30MM
is ideal for use with OMNI-BEAM sensors). Attach two individual glass fiber optic assemblies or one
bifurcated glass fiber optic assembly to the OSBFAC, following the instructions packed with the fibers.
Mount and align the sensing end(s) of the fiber(s), at the sensing location, in a position that will optimize
the differential between the "light" and "dark" conditions. Refer to the data sheet packed with the power
block in use. Connection of the load at this time is optional: the LOAD LED, shown in the photo (right),
will simulate the action of the load. Connect the power block to a compatible power source and apply power.
3) Present the "light" condition to the sensor*. Check to assure that the LOCK LED is "on". If necessary,
adjust the position of the fiber sensing tips so that the LOCK indicator reliably stays "on". While observing
the LOAD LED (and remembering the programmed pulse time, step #1), simulate the sensing situation by
presenting the sensing event to the sensor. If necessary, adjust the GAIN control (clockwise = increase;
counterclockwise = decrease) so that the LOAD LED changes state positively and reliably in response to
all desired variations of the sensing event. Note: Too much gain may result in response to unwanted
conditions (i.e. movement of fiber sensing ends due to vibration, etc.). While observing the LOAD
indicator, adjust the OLM8 timing exactly as desired. Connect the load to the sensor, and test the system.
*Note: If the "light" condition is a quick transition that cannot be simulated as a static condition, present
the "dark" condition in lieu of the "light" condition.

Models available for diffuse, convergent, and fiber optic
sensing modes, and for ac or dc supply voltages
Banner Analog OMNI-BEAM™ Sensors combine the proven optical
performance of standard OMNI-BEAM™ sensors with a 0 to 10V dc
or 10 to 0V dc sourcing analog output power block to produce a highly
versatile and practical analog photoelectric control. Analog photoelectric sensors are especially useful in applications such as process
control, where it is necessary to monitor an object's position or size to
produce a variable control voltage for an analog device such as a motor
speed control. Analog photoelectric sensors are also used to monitor
the optical reflectivity or optical clarity of materials.
Analog OMNI-BEAM sensors provide a variable dc voltage output
that is either directly related ("non-inverting" output) or inversely
related ("inverting" output) to the strength of the received light signal.
When properly adjusted, the two analog outputs are mirror-images of
each other, with their output voltage plots intersecting at 5 volts (see
page 3). Each sensor has multi-turn NULL and SPAN controls to set
the minimum and maximum limits of the sensor's sourcing voltage
outputs. An innovative, custom-designed analog sensor circuit design
allows NULL and SPAN to be adjusted without interaction, greatly
simplifying the setup adjustment procedure. A convenient 10-element
moving-dot LED array gives a visual indication of relative light signal
change and power block voltage output to within the nearest volt.
Analog OMNI-BEAM sensors consist of two basic "building blocks":
a sensor head and a power block. The sensor head contains optical
components, an analog amplifier, NULL and SPAN adjustment controls, and LED indicator array circuitry. Sensor heads are available for
diffuse, convergent, and fiber optic sensing modes. Fiber optic mode
models include infrared and visible-light glass fiber optic models, and
a visible-light plastic fiber optic model. The power block contains
power supply and analog voltage output circuits, and is offered in
three basic models: model OPBT3 (for +15 to 30V dc), model OPBA3
(for 105 to 130V ac), and model OPBB3 (for 210 to 250V ac). Power
block models are listed in the table on page 2.

Output:
The output is an analog voltage that is related to the intensity of the
light reaching the receiver.
The relationship between the 0 to 10V dc analog output voltage and
the received light signal intensity is determined by the wiring
configuration, and may be either direct or inverse.
Output capacity 10mA, maximum. Both outputs may be used
simultaneously, but the maximum total load may not exceed
10mA. Outputs are protected against short-circuit and overload.

Specifications (continued from page 1)
Response time: Output response is the sum of the sensor's fixed R-C
time constant and the programmable R-C time constant. 63% of any
output transition will occur within the period of the total time constant.
Fixed response times are as follows:
OASBD, F, FV, FP sensor heads = R-C time constant 1.5 ms
OASBCV sensor head = R-C time constant 3.3 ms
OASBDX, FX sensor heads = R-C time constant 15.0 ms
The programmable R-C time constant is set using the switches located at
the base of the sensor head (see "Adjustment Procedure", page 3):
All switches "off" = 1 ms
Switch #3 "on" = 1 sec
Switch #1 "on" = 10 ms
Switch #4 "on" = 10 sec
Switch #2 "on" = 100 ms
If more than one switch is "on", the time constant is additive.
Adjustments:
NULL: Null is adjusted (for the condition of greatest received light) until
the #1 LED on the moving dot LED output display just turns "off" (only
the POWER indicator LED should be "on" at this point). Further decrease
the NULL adjustment until the inverting output just reaches 0 volts, or
until the non-inverting output just reaches +10V dc. Refer to the
Adjustment Procedure (page 3) and the hookup diagrams below.
SPAN: Span is adjusted to produce the desired voltage swing between the
lightest and darkest sensing conditions. Minimum guaranteed signal
contrast (i.e. minimum SPAN) which will result in a 10 volt output swing
is 1.5:1. Maximum guaranteed signal contrast (i.e. maximum SPAN) that
will result in a 10 volt output swing is 16:1.
Both controls are 15-turn clutched potentiometers with slotted brass
elements, located beneath a gasketed cover on top of the sensor. A small,
flat-bladed screwdriver is required for adjustment.
Status indicators:
Located on top of the sensor head:
Power ON: a red LED lights whenever power is applied to the power
block;
Output: Ten-element moving-dot LED array indicates approximate voltage output.
Output connector:
6-foot attached PVC-covered cable is standard. Cable may be spliced:

to the circuit to be controlled. See Specifications section (page 1) for information on power block output load capacity. Below is a list of power block
modules that may be used with the Analog OMNI-BEAM sensor block modules. Sensor block and power block must be ordered separately.

3) To adjust the inverting output: monitor the voltage
on the black wire. Adjust the NULL control to the point
where the output just reaches 0 volts*. Then present to the
sensor the "darkest" expected sensing condition (the condition that results in least light seen by the receiver), and adjust
the SPAN control to just reach 10 volts output.

2) Begin with the sensor mounted at the sensing position and connected, per the hookup diagrams
on page 2, for the desired output (inverting or non-inverting). The most precise adjustment is attained
by using a voltmeter connected to monitor the desired
output, as shown in the hookup diagrams. Present the
"lightest" expected sensing condition to the sensor (the
condition that results in the most light seen by the receiver).
Next, perform either step #3 or step #4.

LED array indicates approximate output
voltage and relative light signal strength.

1) Before adjusting the NULL and SPAN, slide the OALM board out from the base of the sensor
head and set the output response time at the DIP switch. Refer to the photo (below right) and the
information printed on the OALM board. Switch settings are given in the Specifications section
(page 2, top). Longer time settings are useful for "smoothing" sensor response. Slide the OALM
board back into the sensor head.

As can be seen from the graph (above, right), the slopes of the two 0-to-10V outputs are mirror-images of each other,
and the plots intersect at 5 volts output. When the 0 and 10 volt points of one output have been properly set, the other
output will track very close to the predicted values.
Other voltage ranges may be used. The practicality of doing so depends upon conditions specific to each individual
application. Substitute the lower voltage for "0 volts", and the higher voltage for "10 volts" in the preceding
adjustment instructions. When a range of other than 0 to 10 volts is used the NULL and SPAN controls will no longer
be non-interactive. If you require further assistance, contact your Banner field sales representative or a factory
applications engineer.
The OALM analog board slides
easily in and out of the sensor head.

Photoelectric Sensing Modes and Their Use in Analog Control
Figure 1. Concept: analog response
B
Increasing voltage
Sensor Output
Every analog sensing application
requires that the sensor produce a
predictable change in output that
directly corresponds with a predicted mechanical change. The
analog sensor output usually produces a measureable change in
voltage or current.
A
In the case of a photoelectric sensor, the mechanical change within
the process being monitored must
produce a change in light intensity
at the sensor's receiver. Most anaIncrease (or decrease)
log sensor applications involve the
in received light level
tracking of a process represented
by a change between specific light
levels, say "level A" and "level B" (see Figure 1).
Diffuse (Proximity) Sensing Mode:
models OASBD and OASBDX
Distance measurement applications include stack height control,
web loop control (Figure 2), and bin level control. Successful
photoelectric distance measurement usually demands that the
reflectivity of the material being sensed remain constant. If the
material being sensed has a specular (shiny) surface, then the angle
of the sensor to the material's surface must also remain constant.
These sensing constraints severely limit the use of photoelectric
Figure 2. Loop control
The best photoelectric sensor for any analog application is one which:
1) Senses the greatest amount of light level change between levels A and B,
2) Produces a constantly increasing or decreasing change change of output
between levels A and B.
Also, in applications where no circuitry is available to integrate or otherwise
condition the sensor output, it is often desireable or necessary that the sensor
produce an output which tracks linearly between levels A and B.
The selection of the best Analog OMNI-BEAM sensor for a specific application is
a matter of:
1) Selecting the sensor head that has the optimum optical response per the above
criteria, and
2) Configuring the sensor optics within the application to optimize these same
criteria.
An understanding of the differences between the various photoelectric sensing
modes greatly simplifies sensor selection decisions. The Banner Handbook of
Photoelectric Sensing offers a discussion of sensing modes. The following discussion presents, in general terms, how each sensing mode is most commonly used for
analog sensing applications.
sensors for distance measurement. For long distance measurement,
analog ultrasonic sensors (Figure 3) are often the first choice.
Ultrasonic sensors measure the elapsed time between a sound
transmission and the returned echo. Consequently, analog ultrasonic
sensors have the benefit of offering an output that is truly linear with
sensing distance.

Sonic OMNI-BEAM application
Diffuse mode sensor heads are primarily used for two types of applications:
1) Distance measurement over relatively long distances (i.e. several inches or
feet), or
2) Reflectivity measurement or monitoring.

OASBD. The sensor's NULL
control is adjusted so that the
received signal at the maximum sensing distance produces an excess gain of 4X. This
is the point at which the inverted output first reaches zero volts, or at which the noninverted output just reaches 10 volts. When NULL is set for 4X excess gain, there is no
interaction between the NULL and SPAN adjustments.
From the plot of maximum NULL, the minimum distance (where excess gain is 4X) can
be as far as 5.5 inches from the sensor lens. The minimum distance can be as close as
.15 inch. However, from .15 inch outward, the excess gain increases until the target is
just over 1.0 inch away, and then decreases. Most applications require the excess gain
to constantly decrease with increasing target distance. It follows that a minimum NULL
setting will place the 4X excess gain point at about 1 inch (i.e. at the top of the curve).
In short, photoelectric analog distance measurement is dependent
upon too many variables to allow meaningful performance curves
to be published. Each Banner Analog OMNI-BEAM sensor head
has a specified maximum response distance. This is the distance to
a 90% reflectance white test card where the excess gain is .25X, and
assumes that the NULL ans SPAN controls are both set to maximum. It is always best to determine analog response empirically.
Whenever possible, sample materials should be sent to Banner's
Application Engineering Group via your local Banner Field Sales
Engineer. When necessary, your process may be avaluated on-site
by our Field Sales Engineer, using test sensors.
Analog OMNI-BEAM model OASBDX may be used with a
retroreflective target (such as model BRT-3) to monitor the gradual
accumulation of dirt, dust, frost, or other contaminants that attenuate
the passage of light (Figure 6). In practice, the retroreflective target
is mounted to a surface where the buildup is to be monitored. In some
applications, the target and sensor lens are both allowed to accumulate buildup. This same technique may be used to monitor density
levels of smoke or other airborne particles which flow between the
OASBDX and its retroreflector.
Figure 6.
Monitoring gradual dirt buildup
Minimum SPAN required to produce a full 10 volt output swing represents an optical
contrast of 1.5:1 (i.e. a change in excess gain from 4X to 2.7X). Maximum SPAN
corresponds to a contrast ratio of 16:1 (i.e. a change from 4X to .25X).
From the excess gain plots for the OASBD, the sensing distances for the limits of
adjustment can be estimated:

Sensor output voltage changes in proportion to change in excess gain. The excess gain
plots for the OSBD (Figure 4) appear fairly linear beyond the signal peak at 1 inch. This
is because the excess gain curve is plotted on a log scale. Excess gain decreases at an
exponential rate with increasing distance. Figure 5 illustrates how the output for model
OSBD would respond at the four extreme settings of the NULL and SPAN controls (as
listed in the table above). These plots are for the inverting output. Note that greater
linearity of response is possible over short distances (i.e. with lower SPAN settings).
Inverting Output (dc volts)
It is important to keep in mind that the actual reflective properties of the material to be
sensed can have a dramatic effect on actual sensor response. The performance reference
for all diffuse mode sensors is a

Convergent Beam Sensing Mode: model OASBCV
A convergent beam sensor uses a lens system that focuses the
emitted light to an exact point in front of the sensor, and focuses the
receiver element on the same point. This is a very efficient use of
reflective sensing energy. Most objects with small profiles can be
reliably sensed.
A convergent beam sensor will detect an object of a given reflectivity
at the sensor's focus point, plus and minus some distance. This
sensing area, centered on the focus point, is called the sensor's depth
of field. The size of the depth of field depends upon the reflectivity
of the object to be sensed. The excess gain curves for model
OASBCV (Figure 7) are plotted using a Kodak 90% reflectance
white test card.
Most of the analog distance measuring applications that use convergent model OASBCV utilize half of the response curve. Distance
measurement usually begins at the focus (1.5 inches from the sensor
lens) and moves farther out, away from the sensor (Figure 8). It is
evicent from the excess gain curve that an analog convergent beam
sensor best monitors object displacements of less than .5 inch.
Much smaller displacements may be measured if the convergent
beam sensor can be located such that the edge of the object enters the
focus point from the side (Figure 9). In this type of application, the
reflectivity of the object and the angle of the object's surfce to the
sensor lens must remain constant.
Specular surfaces can "confuse" a convergent beam sensor. When
viwed straight-on, mirror-like reflections can cause a shiny surfce to
Clearwater Tech - Phone: 800.894.0412 - Fax: 208.368.0415 - Web: www.clrwtr.com - Email: [email protected]
be seen far beyond the normal
depth of field, and small changes
in viewing angle can cause complete loss of the received light
signal.
Model OASBCV uses a visible
red (650nm) light source. Consequently, this sensor may be
used successfully in some applications to monitor the
reflectivity differences contributed by a change in object color.
However, a convergent beam
sensor may be used to monitor
such color changes only if the
sensing distance and other factors contributing to the object's
surface reflectivity remain constant. Color monitoring applications always require a feasibility study. Your Banner Field
Sales Engineer or Factory Applications Engineer can assist
with testing.

Modes: models OASBF,

Fiber optics offer many possibilities for analog sensing and control. Individual fiber optics may
be used for opposed or mechanical convergent sensing. Bifurcated fiber optics may be used for
diffuse mode sensing. Selection
of fiber diameter (plastic fibers)
or fiber bundle diameter (glass
fibers) affords a means of customizing the sensing optics for
optimum analog response. Fiber
optics also offer ease of sensor
mounting, especially in tight locations.
Figure 9. Displacement Measurement
Individual fiber optics:
Glass or plastic individual fiber optics are used in an opposed configuration for distance
measurement (Figure 10). If a pair of fibers are kept in alignment with one another while
moving apart, the decrease in excess gain is predicted directly by the inverse square law.
This fact is illustrated by the straight-line excess gain curves for opposed mode sensors
(Figure 11). Long distance measurement is accomplished by adding lens assemblies to
individual fiber optics with threaded end tips. Give consideration to the warnings about
flexing of glass fiber
optics whenever a fiber optic is repeatedly

A pair of fiber optics
with a small fiber or

One way to accurately
measure small displacements is to position a pair of opposed
fiber optics so that the

grees, etc) from the perpendicular to the specular surface that is to be monitored
for angular skew.
Opposed fiber optics may
be used to measure the width
(profile) of an object as a
function of the percentage
of the beam that it blocks.
This same approach is used
for monitoring the position
of the edge of an opaque
material. One common application is edge-guiding, as
shown in Figure 15. Glass
fiber optics with rectangular terminations serve an
important role in many size
and position monitoring
applications.
Figure 15. Fiber optic opposed edge guiding
Figure 16. Turbidity monitoring
Opposed fiber optics are
commonly applied for
monitoring the optical clarity of a material. For example, a clear section of tubing is often inserted along a
gas or liquid pipeline, and
opposed fiber optics are used
to establish a light path
across the centerline of the
tubing (Figure 16). Turbidity, chemical change, pollutants, etc. may affect the
amount of light transmitted
across the clear section. The
light source of models
OASBF and OASBFX is
infrared (invisible) and the light source used for models OASBFV and OASBFP is
visible red. The light-absorbing characteristics of the material being monitored may
dictate the use of either visible red or infrared light. Whenever necesary, please contact
your Field Sales Engineer or the Banner Application Engineering staff to discuss your
particular sensing requirements.
Bifurcated fiber optics:
Bifurcated fiber optics may sometimes be successfully applied to monitor distance to
a surface (Figure 17). As the excess gain curve in Figure 18 suggests, distance
measurement with bifurcated fiber optics is possible only over relatively short ranges.
Repeatability of distance sensing with bifurcated fiber optics demands that the reflectivity
of the surface and the viewing angle to the surface remain constant. Once the relative
reflectivity of the surface to be monitored is known, the desired response to the predicted
displacement can be obtained through selection of sensor head and fiber (or fiber bundle)
size. Your Banner Field Sales Engineer or Factory Applications Engineer can assist you
with the best selection.

objects. It includes Banner's patented* D.A.T.A.™ system (see
below), a complete early warning diagnostic system that enables
precise monitoring of light signal strength and also alerts you to
potential sensing problems before they occur.
The OSBLVAGC sensor head module is built with a low switching
hysteresis design. This, in combination with the unequalled signal
strength and optical contrast indicating capabilities of the D.A.T.A.

on page 5.
DC power block modules operate from 10-30V dc and include
Banner's exclusive Bi-Modal™ solid-state output circuitry which
includes both sinking and sourcing switching capabilities, depending
upon the hookup configuration used. Each output is capable of 100
mA continuous load.
AC power blocks modules are available for either 105-130V or 210250V ac. The output device is a solid-state relay capable of 500 mA

Standard power blocks include an alarm output that signals the
existence of sensing problems detected by the D.A.T.A. system.
The special lens of the OSBLVAGC polarizes the emitted light and
filters out unwanted reflections. A multi-turn GAIN control enables
the precise sensitivity adjustment needed in low-contrast applications.
The OSBLVAGC may also be used with optional timing logic
modules (see page 5), which plug easily into the bottom of the sensor
head and may be added to the sensor at any time.
The Banner model OSBLVAGC must be paired with a standard
OMNI-BEAM ac or dc power block module, which provides operating voltages to the sensor head and contains the sensor output switch-

The OMNI-BEAM model OSBLVAGC Sensor Block includes Banner's
exclusive, patented D.A.T.A.™ light system. D.A.T.A. is the first and
only complete early warning self-diagnostic system. A multiple-element
LED display is used to warn of an impending sensing problem due to any
of the following causes:
Severe condensation or moisture
High temperature
Low supply voltage
Output overload (dc operation)
Gain too high
Low gain
Low optical contrast (light-to-dark differential)
When one or more of these sensing parameters goes beyond its predefined
limits, the D.A.T.A. lights identify the cause of the problem by flashing a
specific LED or a combination of LEDs in the array. Additionally, a
separate alarm output changes state to signal the system controller or
personnel that sensing conditions have become marginal.

The ten-element LED array also serves as a signal strength indicator that
permits optimum alignment and continuous monitoring of signal strength
and sensing contrast.

D.A.T.A.™ SensorSelf-diagnostic System (US patent #4965548)
D.A.T.A. System Description
Banner's exclusive D.A.T.A. (Display and Trouble Alert) system warns of marginal sensing
conditions usually before a sensing failure occurs. This self-checking diagnostic system warns of
a problem by flashing one or more lights in a multiple-LED array, and by sending a warning signal
to the system logic controller (or directly to an audible or visual alarm) by way of the OMNIBEAM's dedicated alarm output.
The D.A.T.A. lights are located on the top of the sensor head and are viewed through a transparent
LEXAN® cover. The D.A.T.A. lights are configured as follows:
Moisture Alert: Severe moisture inside the sensor head, caused
1
by condensation or by entry of moisture when the access cover is removed,
will cause the #1 light to flash.
High Temperature Alert: When the temperature inside the sensor
2
head exceeds 70°C (+158°F), the #2 light will flash.
Low Voltage or Overload Alert: The number #3 light will flash
3
whenever the sensor supply voltage drops below the minimum that is specified for the power block in use (see power block specifications,
page 5). Power block outputs are also shut down to prevent damage to the load(s) from low voltage.
When using dc power block models OPBT2, OPBT2QD, or OPBT2QDH, the #3 light will flash if either the load output or the alarm output becomes
shorted. Both outputs will be inhibited, and the circuit will "retry" the outputs every 1/10 second. The outputs will automatically reset and function
normally when the short is corrected.
High Gain Warning: The #9 light will flash if the "dark" signal never goes below #4 on the display, and instruct the operator to decrease
9
the gain (see photo above). There are two possible conditions:
1) The High Gain Warning alarm will come "on" if the "dark" signal slowly increases to the #4 level and remains at that level for a
predetermined delay time. This condition is commonly caused by an increase (over time) of unwanted background reflections when using reflective
sensing modes, such as diffuse (proximity) and convergent beam. The alarm will reset as soon as the cause of the unwanted light signal is removed,
or if the GAIN control setting is reduced to bring the "dark" condition below the #4 level.
2) The High Gain Warning alarm will latch "on" if the "dark" signal does not fall below the #4 level during a sensing event. The alarm is
automatically reset on any subsequent sensing event in which the "dark" sensing level falls below the #4 level. This is accomplished by reducing the
GAIN control setting and/or by removing the cause of the unwanted light return in the "dark" condition.
Low Gain Warning: The #10 light will flash if the "light" signal never goes above #5 on the display, and instruct the operator to increase
10
the gain (see photo, above). There are two possible conditions:
1) The Low Gain Warning alarm will come "on" if the light signal slowly decreases to the #5 level and remains at that level for a predetermined
delay time. This situation most commonly occurs in opposed or retroreflective sensing systems, and is caused by a decrease in light in the unblocked
condition (over time) due to obscured lenses or gradual sensor misalignment. The alarm will reset as soon as the light signal strength exceeds the #5
level.
2) The Low Gain Warning alarm will latch "on" if the light signal does not exceed the #5 level during a sensing event. The alarm is
automatically reset by any subsequent sensing event in which the "light" signal exceeds the #5 level. This is accomplished by increasing the GAIN
control setting and/or by lens cleaning and sensor realignment.
Low Contrast Warning: The #9 and #10 D.A.T.A. lights will flash simultaneously to indicate that there is not enough optical contrast
9
+
10
for reliable sensing. This occurs when the "light" condition is at the #5 level and the "dark" condition is at the #4 level for a sensing event.
If this warning occurs, the application should be fully re-evaluated to find ways to increase the differential between the "light" and "dark"
conditions. The Low Contrast alarm is automatically reset by any subsequent sensing event in which the "light" signal exceeds the #5
level and the "dark" signal falls below the #4 level.
SENSE and LOAD Indicator LEDs
SENSE
The SENSE LED indicates when a target has been sensed. When the sensor head is programmed for LIGHT operate, it lights when
the sensor receives enough light to exceed the #5 threshold. When programmed for DARK operate, it lights when the received signal
falls below the #5 threshold. The SENSE LED is located at the far left end of the D.A.T.A. array.
LOAD
The LOAD indicator LED lights whenever the load is energized (after the timing function, if any). The LOAD LED is located at
the far right end of the D.A.T.A. array.
The SENSE and LOAD indicator LED locations are visible in the photograph above.

OSBLVAGC Sensor Head
Alarm and Output Programming
OMNI-BEAM sensor heads are field-programmable for alarm output configuration and for light- or dark- operate. The
DIP switch, inside the sensor block, is accessible with the sensor block removed from the power block.
Switch #1 selects alarm output configuration. With switch #1 "on", the alarm output is normally open (i. e., conducts
Programming Switch
Switch location
with an alarm). Turning switch #1 "off" sets the alarm output to normally closed operation (i.e., output opens during
an alarm).
The normally closed mode (switch #1 "off") is recommended. This allows a system controller to recognize a sensor
power loss or an open sensor output as an alarm condition. The normally open alarm mode (switch #1 "on") should be
used when the alarm outputs of multiple OMNI-BEAMs are wired in parallel to a common alarm or alarm input.
Switch #2 selects LIGHT operate (switch #2 "off") or DARK operate (switch #2 "on"). In the LIGHT operate mode,
the OMNI-BEAM's load output will energize (after a time delay, if timing logic is employed) when the received light
level is greater than the sensing threshold (i.e., when five or more D.A.T.A. lights are illuminated). In DARK operate,
the output will energize (after a time delay, if any) when the received light level is less than the sensing threshold (i.e.,
when four or less D.A.T.A. lights are illuminated).When sensing in the retroreflective mode:
1) The DARK operate mode would be used to energize the OMNI-BEAM's output whenever an object is present,
and blocking the beam.
2) The LIGHT operate mode would be used to energize the output whenever the beam is unblocked (i.e., object missing).
Theory and Setup
The OSBLVAGC's special polarizing lens reduces the possibility of false
sensor response from reflections that may be returned from the object. In
the case of glass objects, light returned from the object is reflected in the
same plane as the emitted light, while the light returned by the retroreflector is rotated 90 degrees by the corner cubes in the reflector. The sensor's
polarizing filter allows only the 90-degree rotated light from the reflector
to pass through to the receiver photoelement. Sensing contrast is
determined by the amount of absorption and scattering that occurs as the
sensing beam passes twice through the glass object.
Plastic objects, due to their differing molecular structures, may rotate,
reflect, and pass light to various extents. Plastics that rotate light 90
degrees and reflect it directly back to the OSBLVAGC cannot be detected
retroreflectively because they can cause the sensor to respond falsely (or
"prox") in what should be the "dark" condition. Plastics that do not reflect
90-degree rotated light back to the sensor can be detected in the same way
as glass objects. Some trial-and-error experimentation may be required.
Contact the Banner Applications Department for assistance. NOTE: as an
alternative to the OSBLVAGC for plastic detection, consider the MINIBEAM Plastic Detector System (SM31EPD/SM31RPD or SMA31EPD/
SM2A31RPD), described in product data sheet P/N 03458.
Other small objects that do not entirely break the sensing beam, such
as yarn and heavy wire or thread, may also be sensed. For such objects,
take particular care to observe condition #1 (below). Use of a smaller
reflector will minimize "spillage" of reflected light around a small object.
Optimum sensor setup is a matter of achieving as much difference in
light level (optical contrast) as possible between the "object present"
(or "dark") and "object absent" (or "light") conditions. Sensing will
be most reliable when the following conditions are met (refer to Fig. 1):
1) The object blocks as much of the sensor's effective beam as
possible. The distance from the sensor to the object(s) should be small in
proportion to the distance between the object and the reflector. The object
should pass as close to the sensor's lens as possible (a distance of as little
as one inch is recommended). This helps to prevent transmitted light (that

Effective beam
The OSBLVAGC is a low-hysteresis retroreflective sensor. Its emitted
light is returned by a retroreflector back to the receiver photoelement. An
object is sensed based on the decrease in reflected light signal at the
receiver photoelement when an object comes between the sensor and the
retroreflector. Low-hysteresis circuit design enables the sensor outputs to
switch based on relatively small changes in light signal levels, such as the
difference in received light level between a "clear object present" (or
"dark") condition and a "clear object absent" (or "light") condition.

sensor
is distorted as it travels through the object) from reaching the reflector.
Also, position the sensor or object such that the long axis of the object will
be parallel to the vertical dividing line between the sensor lenses. Whenever possible, the object should present its largest dimension to the sensor.
2) Sensing reliability depends upon sensing contrast; therefore, there
must be enough space between consecutive objects to establish a
strong "light" condition. If the space is smaller than the effective beam
diameter, sensing contrast will be diminished.
3) The object-to-sensor distance is held constant (e.g. the object's
position is constrained by guide rails).
4) The sensor's lens window and the retroreflector are kept clean and
properly aligned to each other. The lower the sensing contrast of the
application, the more important is a clean reflector! Also, be aware that
condensation on the reflector will reduce its efficiency. Proper sensorreflector alignment is discussed in Setup Procedure (below).
Before attempting to set up the OSBLVAGC, read and understand
D.A.T.A. system Description (page 2) and Measuring Excess Gain and
Contrast (page 4).
Setup Procedure
1) Select the location at which sensing will take place. Mount the sensor
in place so that it cannot be moved inadvertently. The sensing location
should conform to the requirements discussed above. (Continued p. 4.)

2) With no load attached, apply power to the sensor. With the aid of an assistant if
necessary, hold the reflector at its approximate mounting position, directly facing the
sensor, and move it up/down and right/left while observing the D.A.T.A. display on
the sensor. Find the center of the zone of reflector movement within which the most
LEDs on the 10-element array remain "on". It may be necessary to decrease (rotate
ccw) or increase (rotate cw) the sensor's 15-turn GAIN control to produce the most
easily "readable" indications for fine tuning the reflector position. Mount the reflector
at the center of this movement zone, directly facing the sensor.
3) Present the object to the sensor at the sensing point. Adjust the 15-turn GAIN
control to light three LEDs on the D.A.T.A. array. Remove the object from the sensing
position and note the number of LEDs that light with the object absent. If six or more
LEDs are lit, optical contrast in the application is adequate. Four or more LEDs lit in
the "dark" condition and/or five or less in the light condition represent inadequate
sensing contrast and will trigger a warning from the sensor head. If possible,
experiment by presenting different "views" of the object to the sensor, for the purpose
of increasing contrast. The GAIN control should be set so that the "dark" signal does
not light more than three LEDs.

SENSOR-TO-REFLECTOR DISTANCE
This curve shows the excess gain of the OSBLVAGC sensor
when it is used with different size retroreflectors. It also shows
the maximum sensor-to-reflector distance for each reflector.
The larger the reflector, the higher the excess gain, the greater
the possible sensor-to-reflector distance, and the wider the
effective beam. If the objects to be sensed are small, a smaller
(or partially masked) reflector might provide better optical
contrast than a larger one. This is because the larger the
reflector used, the larger the sensor's effective beam. Refer to
Figure 1 (page 3). A larger reflector might cause light to "spill"
around the edges of a small object and increase the light signal
that the sensor sees in the "dark" condition.
Measuring Excess Gain and Contrast
The OMNI-BEAM's D.A.T.A. lights may be used to measure the
excess gain and contrast in any sensing situation and during
installation and maintenance.
Excess gain is a measurement of the amount of light energy
falling on the receiver of a photoelectric sensor over and above
the minimum amount necessary to operate the sensor's amplifier.
Excess gain is expressed as a ratio:
Excess gain (E.G.) = light energy falling on receiver
amplifier threshold

The amplifier threshold is the point at which the sensor's output switches. The OMNI-BEAM's threshold corresponds to the #5 level of the
D.A.T.A. light array. That is, when LEDs #1 through #5 are lit, the excess gain of the received light signal is equal to "1x".
The table above (Relationship between Excess Gain and D.A.T.A. System Lights) shows how excess gain relates to the D.A.T.A. light array indication.
Contrast is the ratio of the amount of light falling on the receiver in the "light" state as compared to the "dark" state. Contrast is also referred
to as "light-to-dark ratio". Optimizing the contrast in any sensing situation will increase the reliability of the sensing system. Contrast may be
calculated if excess gain values are known for both the light and dark conditions:
Contrast =Excess gain (light condition)
Excess gain (dark condition)
To determine the contrast for any sensing application, present both the "light" and "dark" conditions to the OMNI-BEAM, and read the D.A.T.A.
signal for each. Take the ratio of the two numbers (from the table above) that correspond to the highest D.A.T.A. light numbers registered for
the "light" and "dark" conditions.
For example, if LEDs #1 through #8 come "on" in the
"light" condition and LEDs #1 and #2 come "on" in the
"dark" condition (as shown in the photos at right), the
contrast (referring to the table above) is calculated as
follows:
Contrast = 1.3x = 1.8
0.7x
This value is expressed as "1.8:1" or "1.8-to-one".
The best sensor adjustment will cause all ten D.A.T.A.
LEDs to come "on" for the "light" condition, and will
cause no LEDs to come "on" in the "dark" condition. This
is rarely possible when sensing clear materials. However,
it is important to always adjust a sensor for the greatest
amount of contrast possible for any sensing situation.
The D.A.T.A. light system makes this easy. Suggestions
for maximizing sensing contrast in your application are
given in the Theory and Setup section on page 3.

system LEDs #1 through #8 lit.

Figure 1. OPBX2 Series Power Blocks
in a Seriplex® stand-alone network
In use, OPBX2 Series Power Block-equipped OMNI-BEAM™ sensors, the
devices to be controlled, a dc power supply, and a clock module all connect to
a common network. One wire of the network supplies dc voltage of +9 to 12
volts, one wire is common (ground), another carries data, and another carries
a synchronous, continuously-recycling clock signal. Each power block has a
built-in EEPROM that is programmed, by the user, to recognize up to two different address codes.
Each power block output is given access to the data line of the network when that
power block is addressed. At that time, the information on the addressed output
becomes available on the data line for control or data collection purposes. The
input(s) to any Seriplex module-equipped device(s) on the network that are to be
controlled by a specific power block output are assigned the same address code as
that power block output. The basic system, called a stand-alone system, requires
no central processor. For applications that require a more complex, central control
system, OPBX2 Series Power Blocks and APC Seriplex network technology
support the use of a host processor. Consult APC for further information.

Power block programming information
The programming information presented in this data sheet is in
addition to the programming procedure details given in the Programming Seriplex™ I/O Modules section of the APC Seriplex
Programmable Control System Instruction Manual provided with
the APC hand-held programmer. Read and understand both the APC
manual and the information below before attempting to program
the OPBX2 Series Power Block.
OPBX2 Series Power Blocks are programmed, by the user, for
three attributes (details below). The APC hand-held programmer
connects to the programming port of the power block using a programming cable (model XPC1A, available from Banner, see Figure
2 for connection information). Programming is typically done at
initial system setup, and may be done either before or after the
power block is wired into the Seriplex network. Since EEPROMs
retain their programmed information in spite of power failures, they
need be reprogrammed only if the usage of the sensor within the
network changes. The three programmable attributes are:
Address number: The load and alarm outputs from Standard
OMNI-BEAM Sensor heads are separate and distinct, and are
addressed separately as channel A (load) and channel B (alarm).
If the alarm signal is not required, assign channel B to an unused
address. When E Series Sensor Heads are used, the normally open
load output from the sensor head appears simultaneously on both
power block outputs (A and B). Addresses are decimal values in
the range of 001 through 255, and need not be assigned in numerical
order. (NOTE: Care should be taken when choosing addresses.
The Seriplex® system will logically "OR" signals with the same
address. See Seriplex® literature for more information.)
Power block output status: Bits 6 and 7 of the control byte
(Figure 3) are used to configure channel B and channel A power
block outputs (respectively). Setting these bits to "1" inverts the
signal within the power block. It is recommended that these bits
be set to "0". Signal inversions may instead be performed via a
dip switch inside the sensor head.
Module mode: Bit 0 in the control byte (Figure 3) is used to
select the power block's mode of operation. Set this bit to "0" if
there is no host processor connected (stand-alone mode). If output
data will be read from the data line as set by a host processor , set
this bit to "1".
Bits 1 and 2 are test bits which are not used in normal operation, and must be set to "1".
