Electrostatic Discharge Awareness
All electronic equipment is static-sensitive, some components more than others.
To protect these components from static damage, you must take special
precautions to minimize or eliminate electrostatic discharges.
Follow these precautions when working with or near the control.
1.
Before doing maintenance on the electronic control, discharge the static
electricity on your body to ground by touching and holding a grounded
metal object (pipes, cabinets, equipment, etc.).
2.
Avoid the build-up of static electricity on your body by not wearing clothing
made of synthetic materials. Wear cotton or cotton-blend materials as
much as possible because these do not store static electric charges as
much as synthetics.
3.
Keep plastic, vinyl, and Styrofoam materials (such as plastic or Styrofoam
cups, cup holders, cigarette packages, cellophane wrappers, vinyl books or
folders, plastic bottles, and plastic ash trays) away from the control, the
modules, and the work area as much as possible.
4.
Do not remove the printed circuit board (PCB) from the control cabinet
unless absolutely necessary. If you must remove the PCB from the control
cabinet, follow these precautions:
•
Do not touch any part of the PCB except the edges.
•
Do not touch the electrical conductors, the connectors, or the
components with conductive devices or with your hands.
•
When replacing a PCB, keep the new PCB in the plastic antistatic
protective bag it comes in until you are ready to install it. Immediately
after removing the old PCB from the control cabinet, place it in the
antistatic protective bag.
CAUTION—ELECTROSTATIC DISCHARGE
To prevent damage to electronic components caused by improper handling,
read and observe the precautions in Woodward manual 82715, Guide for
Handling and Protection of Electronic Controls, Printed Circuit Boards, and
Modules.

System Description
Introduction
The 723PLUS control for this application receives an analog speed setting
signal from an external system. The 723PLUS biases this speed reference for
synchronizing purposes, kW droop, and to make the kW base load control
possible.
Depending on the actual speed, the control will set maximum load setpoints that
will act as a torque limit curve.
Control functions include:
•
Speed sensing
•
Speed reference
•
Droop / KW Control
•
Speed Control
•
Fuel Limiters
•
Alarms
Speed Sensing
The speed sensing of the engine is done by one or two speed sensors. The
speed sensors can be proximity probes or magnetic pick-ups.
The influence of the engine firing frequencies is attenuated by a low pass filter.
Speed fault indication
The speed channels are continuously checked for speed sensor failures. A
failure is latched when the speed signal drops below 10 rpm or raises above
2000 rpm. The speed sensor fault detection is overridden during shutdown and
stays overridden for *10 seconds after Run is selected.
Because the 723PLUS does not act as speed control unit, a double failure of
the speed probes does not result in a major alarm. Each sensor can individual
be setup, in case of failure, as minor alarm or major alarm.
Speed Reference
On starts the control will run the engine on min speed and will ramp the speed
after a adjustable delay to rated. The speed reference can be adjusted by the
Raise and Lower contacts or the Remote Speed Reference. To select remote
speed reference both the raise and lower contact have to be made. On failure of
the remote reference signal the speed can be controlled by the raise and lower
contacts.
The speed reference can be adjusted between the Min. Speed Limit and Max.
Speed Limit (adjustable in Configure). The range of the remote speed reference
is determined by 4mA Rem. Ref. and 20mA Rem Ref. An analog input below
2 mA or above 22 mA will create an alarm.

Woodward
Manual 26425
723PLUS Nile River Generator Control
Droop / KW Control
Load sharing with other prime movers is done in droop. The main engine control
has this droop function already internally. For that reason, the droop amount in
the 723PLUS is set default to 0%. In case the kW droop must be activated, the
droop % must be set to the correct amount. In kW droop, the control uses the
load sensor input to calculate the droop. The load can be controlled with the
raise and lower or the remote speed setpoint.
If the load reference enable switch is closed, the control can act in kW control.
The range of the remote load reference is determined by the 4mA KW Ref and
the 20 mA KW Ref. An analog input below 2 mA or above 22 mA will create an
alarm on both the remote reference and the load sensor. An alarm of one or
both the inputs will disable the KW Control.
Shutdown
The shutdown function, when activated by the external Run/Stop contact, sends
a minimum Speed reference signal out. Also in the configure menu one can
select if the speed reference should go to minimum speed reference on the
event of a Major alarm.
Fuel Limiters
A four-point Speed / KW limiter is present to prevent overloading of the engine
dependable on speed. This will overrule the kW setpoint in case this demand
will be too much at the actual speed. An additional four-point curve is present to
allow a certain extra kW amount per speed setpoint. This can be used in case
the torque limit is too critical at certain speed setpoints! Always contact the
engine OEM for the correct settings.
Alarms
In this application the following I/O signals can cause an alarm:
•
Speed Probe # 1 input
•
Speed Probe # 2 input
•
Remote Speed Reference input
•
Load sensor input
•
Remote Load Reference input
These inputs have three types of alarms: no alarm, minor alarm, and major
alarm. In the configure mode the type of alarm can be chosen:
•
1 means no alarm
•
2 means minor alarm
•
3 means major alarm
The following failure will always give a major alarm:
•
Overspeed
The Overspeed Trip level can be adjusted in the configure mode.
A minor alarm will activate the minor alarm relay output. A major alarm will
create a shutdown and will activate the major alarm relay output. To reset an
alarm use the external reset.
The shutdown on major alarm can be adjusted to no shutdown on major alarm
(when mechanical backup and reverse acting is used)and the relay’s can be
adjusted to have NO or NC contacts.
The remote speed input and manifold pressure input can be adjusted as not
used. In that case the alarms are overridden and the manifold limiter is set at
maximum output.

Hand-held Programmer
Hand-held Programmer and Menus
The Hand-held Programmer is a hand-held computer terminal that gets its
power from the Control. The terminal connects to the RS-422 communication
serial port on the control.
The programmer does a power-up self-test whenever it is plugged into the
control. When the self-test is complete, the screen displays two lines of
information. This is information relating to the application. Pressing the 'ID' key
changes the display to show the Woodward logo with the country name
("Woodward (NL)") and application name of the system. Press ‘ID’ again for the
software part number.
The programmer screen is a four-line, back lighted LCD display. The display
lets you look at two separate functions or menu items at the same time. Use the
“Up/Down Arrow” key to toggle between the two displayed items (an “@”
indicates the item in the active menu). Use the BKSP and SPACE keys to scroll
through the display to show the remainder of a prompt if it is longer than the
display screen's 18 characters.
The Control has three sets of menus: the Service menus, the Configure menus
and the Debug menus. The Service menus allow easy access and tuning while
the engine is running. The Configure menus may only be entered if the I/O is
shutdown, and hence the engine stopped. The Debug menu allows access to
the GAP software.
Configure Menus
To access the Configure menus, the engine must be shutdown. Press the . key.
The display will show, 'To Enable CONFIGURE Press *ENTER*'. Press the
ENTER key and the display will show, 'To Shutdown I/O, Press *ENTER*'.
Press the ENTER key and this will allow you to get into the Configure menus.
CAUTION—ENGINE SHUTDOWN
If the engine is running, it will be shut down because the control’s I/Os are
disabled.
To move between the menus use the S and T keys. To move through the
setpoints within a menu use the W and X keys,. Once in a menu, press the
ESC key to return to the menu header.
To leave the Configure menus press the ESC key. The message 'Rebooting
Control' will appear. The setpoints are automatically saved when leaving
Configure.
Service Menus
To access the Service menus press the T key. To move between menus, and
to move through setpoints within menus, follow the instructions as for the
Configure menus. Also to return to the menu header, or to leave Service, follow
the Configure instructions.

Woodward
Manual 26425
723PLUS Nile River Generator Control
Debug Menus
To access the Debug first press „ (solid square) after which the T key should
be pressed. To move between category menus use the W and X keys, once in
the right category move through the GAP blocks by using the S and T keys.
Within a GAP block every output and tunable (*) input can been seen by using
the W and X keys.
A Tunable (*) can be changed by using the “Turtle Up” or the “Rabbit Up” keys
to increase the value, and the “Turtle Down” or “Rabbit Down” keys to decrease
the value (see also adjusting setpoints).
To return to the menu header press the T key, or to leave Service, follow the
Configure instructions.
Adjusting Setpoints
To adjust a set point, use the “Turtle Up” or the “Rabbit Up” keys to increase the
value, and the “Turtle Down” or “Rabbit Down” keys to decrease the value. The
“Rabbit Up” and “Rabbit Down” keys will make the rate of change faster than
the “Turtle Up” and “Turtle Down” keys. This is useful during initial set-up where
a value may need to be changed significantly. Where necessary, to select
TRUE, use either the “Turtle Up” or the “Rabbit Up” keys, and to select FALSE,
use the “Turtle Down” or “Rabbit Down” keys.
To obtain an exact value, press the “=“ key. Key in the required figure and press
ENTER.
NOTE
This may only be done if the figure is within 10% of the existing value.
To save setpoints at any time, use the SAVE key. This transfers all new setpoint
values into EEPROM memory. The EEPROM retains all setpoints when power
is removed from the control.
CAUTION—SAVE SETPOINTS
To prevent possible damage to the engine resulting from improper control
settings, make sure you save the setpoints before removing power from the
control. Failure to save the setpoints before removing power from the
control causes them to revert to the previously saved settings.
Hand-Held Programmer Keys
The programmer keys have the following functions (see Figure 4-1):

plus a core charge at the time the replacement unit is shipped. If the core (field
unit) is returned to Woodward within 60 days, Woodward will issue a credit for
the core charge. [The core charge is the average difference between the flat
rate replacement/exchange charge and the current list price of a new unit.]
Return Shipment Authorization Label. To ensure prompt receipt of the core,
and avoid additional charges, the package must be properly marked. A return
authorization label is included with every Replacement/Exchange unit that
leaves Woodward. The core should be repackaged and the return authorization
label affixed to the outside of the package. Without the authorization label,
receipt of the returned core could be delayed and cause additional charges to
be applied.

Electrostatic Discharge Awareness
All electronic equipment is static-sensitive, some components more than others.
To protect these components from static damage, you must take special
precautions to minimize or eliminate electrostatic discharges.
Follow these precautions when working with or near the control.
1.
Before doing maintenance on the electronic control, discharge the static
electricity on your body to ground by touching and holding a grounded metal
object (pipes, cabinets, equipment, etc.).
2.
Avoid the build-up of static electricity on your body by not wearing clothing
made of synthetic materials. Wear cotton or cotton-blend materials as much
as possible because these do not store static electric charges as much as
synthetics.
3.
Keep plastic, vinyl, and Styrofoam materials (such as plastic or Styrofoam
cups, cup holders, cigarette packages, cellophane wrappers, vinyl books or
folders, plastic bottles, and plastic ash trays) away from the control, the
modules, and the work area as much as possible.
4.
Do not remove the printed circuit board (PCB) from the control cabinet
unless absolutely necessary. If you must remove the PCB from the control
cabinet, follow these precautions:
•
Do not touch any part of the PCB except the edges.
•
Do not touch the electrical conductors, the connectors, or the
components with conductive devices or with your hands.
•
When replacing a PCB, keep the new PCB in the plastic antistatic
protective bag it comes in until you are ready to install it. Immediately
after removing the old PCB from the control cabinet, place it in the
antistatic protective bag.
CAUTION—ELECTROSTATIC DISCHARGE
To prevent damage to electronic components caused by improper handling,
read and observe the precautions in Woodward manual 82715, Guide for
Handling and Protection of Electronic Controls, Printed Circuit Boards, and
Modules.

General Information
Introduction
This manual describes the Woodward 723PLUS Digital Control hardware,
9906-619 (low voltage) 9906-620 (high voltage), and 9906-700 (modified
actuator filtering, low voltage). These part numbers are EU Directive compliant
components.
Declaration of Incorporation
In accordance with the EMC Directive 89/336/EEC and its amendments, this
controlling device, manufactured by the Woodward Governor Company, is
applied solely as a component to be incorporated into a prime mover system.
Woodward declares that this controlling device complies with the requirements of
EN50081–2 and EN50082–2 when put into service per the installation and
operating instructions outlined the product manual.
NOTICE: This controlling device is intended to be put into service only upon
incorporation into a prime mover system that itself has met the requirements of
the above Directive and bears the CE mark.
Application
The 723PLUS Digital Control can be programmed to suit applications requiring
two magnetic pickups (MPUs) or proximity switches (e.g. for torsional filtering) as
the hardware includes two speed inputs. It also includes four analog inputs, three
analog outputs, eight discrete inputs and three discrete outputs, all of which can
be programmed to satisfy the application. The control can be used in load
sharing systems as it contains circuitry and connections to support this.
The two LON channels can be used to support Woodward LonTalk® or LinkNet®
input/output nodes control functions.
The 723PLUS control (Figure 1-1) consists of a single printed circuit board in a
sheet-metal chassis. Connections are via three terminal strips and three 9-pin
subminiature D connectors.
Control Options
The 723PLUS control requires the following power supply input voltages, with 40
watts as the nominal power consumption at rated voltage:
•
18–40 Vdc (24 or 32 Vdc nominal)
•
90–150 Vdc (125 Vdc nominal)
Discrete input voltages provide on/off command signals to the electronic control.
Each discrete input requires 10 mA at its 24 Vdc nominal voltage rating (for 24
volt switching logic).

723PLUS Hardware Manual
Manual 02877
Shielded Wiring
All shielded cable must be twisted conductor pairs. Do not attempt to tin the
braided shield. All signal lines should be shielded to prevent picking up stray
signals from adjacent equipment. Connect the shields to the nearest chassis
ground. Wire exposed beyond the shield should be as short as possible, not
exceeding 50 mm (2 inches). The other end of the shields must be left open and
insulated from any other conductor. DO NOT run shielded signal wires along with
other wires carrying large currents. See Woodward application note 50532,
Interference Control in Electronic Governing Systems for more information.
Where shielded cable is required, cut the cable to the desired length and prepare
the cable as instructed below.
1. Strip outer insulation from BOTH ENDS, exposing the braided or spiral
wrapped shield. DO NOT CUT THE SHIELD.
2. Using a sharp, pointed tool, carefully spread the strands of the shield.
3. Pull inner conductor(s) out of the shield. If the shield is the braided type, twist
it to prevent fraying.
4. Remove 6 mm (1/4 inch) of insulation from the inner conductors.
Installations with severe electromagnetic interference (EMI) may require
additional shielding precautions. Contact Woodward for more information.
Power Supply (Terminals 1/2)
Power supply output must be low impedance (for example, directly from
batteries). DO NOT power the control from high-voltage sources with resistors
and zener diodes in series with the control power input. The 723PLUS control
contains a switching power supply which requires a current surge to start
properly.
CAUTION—INPUT VOLTAGE
To prevent damage to the control, do not power a low-voltage control from
high-voltage sources, and do not power any control from high- voltage
sources with resistors and zener diodes in series with the power input.
Run the power leads directly from the power source to the control. DO NOT
POWER OTHER DEVICES WITH LEADS COMMON TO THE CONTROL. Avoid
long wire lengths. Connect the positive (line) to terminal 1 and negative
(common) to terminal 2. If the power source is a battery, be sure the system
includes an alternator or other battery-charging device.
If possible, do NOT turn off control power as part of a normal shutdown
procedure. Leave the control powered except for service of the system and
extended periods of disuse.
CAUTION—DO NOT APPLY POWER
Do NOT apply power to the control at this time. Applying power may damage
the control.
To prevent damage to the engine, apply power to the 723PLUS control at
least 60 seconds prior to starting the engine. The control must have time to
do its power up diagnostics and become operational. Do not start the engine
unless the green POWER AND CPU OK indicator on the 723PLUS control
cover comes on, because test failure turns off the output of the control.

Woodward
Manual 02877
723PLUS Hardware Manual
Analog Outputs (#1 & #2) (Terminals 15/16 & 17/18)
Use shielded twisted-pair wires to connect to terminals 15(+) & 16(–) and 17(+) &
18(–). For an electrically isolated input device such as a 4 to 20 mA input analog
meter, the shield should be grounded at the control end of the cable. For input to
other devices, use the recommendation of the device manufacturer.
CAUTION—GROUND LOOPS
To prevent possible damage to the control or poor control performance
resulting from ground loop problems, we recommend using current-loop
isolators if the 723PLUS control's analog inputs and outputs must both be
used with non-isolated devices. A number of manufacturers offer 20 mA
loop isolators. Consult Woodward for further information.
Analog Outputs (#3 & #4) (Terminals 19/20 & 21/22)
The actuator wires connect to terminals 19(+) & 20(–) and 21(+) & 22(–). Use
shielded wires with the shield connected to chassis at the control.
Speed Signal Inputs (Terminals 11/12 & 13/14)
Connect a magnetic pick-up (MPU) or proximity switch (see NOTE on page 2) to
terminals 11 and 12. You may need to connect a second MPU/proximity switch
to terminals 13 and 14 (see relevant application manual). Use shielded wire for
all speed sensor connections. Connect the shield to the chassis. Make sure the
shield has continuity the entire distance to the speed sensor, and make sure the
shield is insulated from all other conducting surfaces.
WARNING—GEAR TOOTH COUNT
The number of gear teeth is used by the control to convert pulses from the
speed sensing device to engine rpm. To prevent possible serious injury from
an overspeeding engine, make sure the control is properly programmed to
convert the gear-tooth count into engine rpm. Improper conversion could
cause engine overspeed.
Load Sharing Lines Input (Terminals 9/10)
Connect the output of a Woodward Load Sensor, or another 723PLUS control's
load sharing lines, to terminals 9(+) and 10(–). Use a shielded twisted-pair cable.
Wire the remainder of the load sensor in accordance with the wiring diagram for
the sensor used.
Discrete Inputs (Terminals 29–36)
For Lloyd’s Register of Shipping applications, use only isolated contacts
(dry or signal rated) for the discrete inputs. Power these contacts from the
control-supplied Aux Voltage.
Discrete inputs are the switch input commands to the 723PLUS control. In low
voltage systems, or other systems where nominal 24 Vdc is available, the
discrete inputs should be powered by this external voltage.

If you are using the control-supplied aux voltage, jumper terminal 37 to terminal
38. This connects the control's common to the discrete input common. Terminal
39 then supplies power (approximately +24 Vdc) to the discrete inputs. Since the
aux voltage is not isolated from other control circuits, use only isolated contacts
(dry or signal voltage rated) for the discrete circuits. DO NOT POWER ANY
OTHER DEVICES WITH THE AUX VOLTAGE SOURCE.
If you are supplying the discrete input voltage (24 Vdc), connect the voltage
source negative (–) to terminal 37 (DO NOT INSTALL THE JUMPER FROM
TERMINAL 37 TO 38). Then run the voltage source positive (+) to the
appropriate switch or relay contact and then to the corresponding discrete input.
Analog Inputs (#1, #2, #3, & #4) (Terminals 42/43, 45/46, 48/49,
& 51/ 52)
Use shielded twisted-pair cable to connect to terminals 42(+) & 43(–), 45(+) &
46(-), 48(+) & 49(–), and 51(+) & 52(–). Ensure that a jumper is installed between
relevant terminals (41 & 42–#1, 44 & 45–#2, 47 & 48–#3, 49 & 50–#4) for the mA
input. These inputs are not isolated from the other control inputs and outputs
(except the power supply input and the discrete inputs). If any other analog input
or output is used in a common ground system, an isolator must be installed. A
number of manufacturers offer 20 mA loop isolators. Consult Woodward for
further information.
Installation Checkout Procedure
With the installation complete, do the following checkout procedure before
beginning set point entry or initial start-up adjustments.
1.
Visual inspection
A. Check the linkage between the actuator and fuel metering device for
looseness or binding. Refer to the appropriate actuator manual, and
Manual 25070, Electric Governor Installation Guide for additional
information on linkage.
WARNING—MINIMUM FUEL POSITION
To prevent possible serious injury from an overspeeding engine, the
actuator lever or stroke should be near but not at the minimum position
when the fuel valve or fuel rack is at the minimum fuel delivery position.
B.
C.
D.
2.

Check for correct wiring in accordance with the plant wiring diagram,
(see relevant Application Manual).
Check for broken terminals and loose terminal screws.
Check the speed sensor(s) for visible damage. If the sensor is a
magnetic pickup, check the clearance between the gear and the
sensor, and adjust if necessary. Clearance should be between 0.25
and 1.25 mm (0.010 and 0.050 inch) at the closest point. Make sure
the gear runout does not exceed the pickup gap.
Check for grounds
Check for grounds by measuring the resistance from all control terminals to
chassis. All terminals except terminals 2 and 38 should measure infinite
resistance (the resistance of terminals 2 and 38 depends on whether a floating
or grounded power source is used). If a resistance less than infinite is
obtained, remove the connections from each terminal one at a time until the
resistance is infinite. Check the line that was removed last to locate the fault.

723PLUS Hardware Manual
Serial Port Communications
The 723PLUS has two serial ports for communications. They may be software
configured as RS-232, RS-422, or RS-485. These ports may be software
configured to function as MODBUS communications ports at the time the
application software is written. If the J2 and J3 port are configured as a MODBUS
port, they will support either MODBUS ASCII or MODBUS RTU protocols.
Termination
For RS-422, termination should be located at the receiver when one or more
transmitters are connected to a single receiver. When a single transmitter is
connected to one or more receivers, termination should be at the receiver
farthest from the transmitter. Figure 2-3 is an example.
Figure 2-3. RS-422 Terminator Locations
Communicating with the OpTrend® operator interface is a special case of Figure 23. Because the OpTrend master cannot put its transmitter into a high-impedance
state, and our bit rate is less than 90k bits/sec, termination is not needed at the
slave. Termination is needed at the OpTrend receiver, but because there is no way
to locate it there, it has to be put at the alternate location.
For RS-485, termination should be at each end of the cable. If termination can’t
be located at the end of a cable, put it as close as possible to the ends. Figure
2-4 is an example.
Figure 2-4. RS-485 Terminator Locations
Woodward

723PLUS Hardware Manual
Manual 02877
If you do not know if a master can put its transmitter into a high-impedance state,
terminate the line as shown in Figure 2-3. It does not hurt to terminate the line
even when it is not needed as in the case of the OpTrend operator interface.
Termination is accomplished using a three-resistor voltage divider between a
positive voltage and ground. The impedance of the resistor network should be
equal to the characteristic impedance of the cable. This is usually about 100 to
120 ohms. The purpose is to maintain a voltage level between the two differential
lines so that the receiver will be in a stable condition. The differential voltage can
range between 0.2 and 6 volts; but the maximum voltage between either receiver
input and circuit ground must be less than 10 volts. There is one termination
resistor network for each port located on the 723PLUS board. Connection to this
resistor network is made through the 9-pin connectors on pins 6 and 9. See
Figures 2-5 through 2-8 for termination and cable connection examples.

Grounding and Shielding
The RS-422 and RS-485 specifications state that a ground wire is needed if
there is no other ground path between units. The preferred method to do this is
to include a separate wire in the cable that connects the circuit grounds together.
Connect the shield to earth ground at one point only. The alternate way is to
connect all circuit grounds to the shield, and then connect the shield to earth
ground at one point only. If the latter method is used, and there are non-isolated
nodes on the party line, connect the shield to ground at a non-isolated node, not
at an isolated node. Figures 2-9 and 2-10 illustrate these cabling approaches.
NOTE
Non-isolated nodes may not have a signal ground available. If signal ground
is not available, use the alternate wiring scheme in Figure 2-10 with the
signal ground connection removed on those nodes only.

Separate Signal Ground Wire

The SG (signal ground) connection is not required if signal ground is unavailable.

Chapter 3.
Entering Control Set Points
Introduction
Due to the variety of installations, plus system and component tolerances, the
723PLUS control must be tuned to each system for optimum performance.
This chapter contains information on how to enter control set points through the
control's menu system using the Hand Held Programmer. If you have access to
the Watch Window software tool and ServLink software, you can set up and tune
the 723PLUS control from a PC (personal computer) using the instructions in
Chapter 5 of this manual.
WARNING—OVERSPEED
An improperly calibrated control could cause an engine overspeed or other
damage to the engine. To prevent possible serious injury from an
overspeeding engine, read this entire procedure before starting the engine.
Hand Held Programmer and Menus
The Hand Held Programmer is a hand-held computer terminal that gets its power
from the 723PLUS control. The terminal connects to the RS-422 communication
serial port on the control (terminal J1). To connect the terminal, slightly loosen
the right-hand screw in the cover over J1 and rotate the cover clockwise to
expose the 9-pin connector. Then firmly seat the connector on the terminal into
J1.
The programmer does a power-up self-test whenever it is plugged into the
control. When the self-test is complete, the screen will display two lines of
information. This is information relating to the application. Pressing the ID key will
change the display to show the part number of the software and version letter.
The programmer screen is a four-line, backlighted LCD display. The display
permits you to look at two separate functions or menu items at the same time.
Use the UP/DOWN ARROW key to toggle between the two displayed items. The
BKSP and SPACE keys will scroll through the display to show the remainder of a
prompt if it is longer than the display screen's 18 characters.
The 723PLUS has two sets of menus—the Service menus and the Configure
menus. The Service menus allow easy access and tuning while the engine is
running. The Configure menus may be entered only if the I/O is shutdown (hence
the engine stopped).
Configure Menus
To access the Configure menus, the engine must be shut down. Press the
key. The display will show, “To select configure, press enter”. Press the ENTER
key and the display will show, “To shutdown I/O, press enter”. Press the ENTER
key and this will allow you into the Configure menus.
Woodward
17
723PLUS Hardware Manual
Manual 02877
NOTE
If the engine is running during this process, it will be shut down due to
shutting down the I/O of the control.
To move between the menus use the LEFT ARROW and RIGHT ARROW keys.
To move through the set points within a menu, use the UP ARROW and DOWN
ARROW keys. Once within a menu, to return to the menu header, press the ESC
key.
To leave the Configure menus press the ESC key. The set points will be
automatically saved when leaving Configure.
Service Menus
To access the Service menus press the DOWN ARROW key. To move between
menus, and to move through set points within menus follow the instructions as
for the Configure menus. Also to return to return to the menu header, or to leave
Service, follow the Configure instructions.
Adjusting Set Points
To adjust a set point, use the TURTLE UP or the RABBIT UP keys to increase
the value, and the TURTLE or RABBIT DOWN keys to decrease the value. The
RABBIT UP and RABBIT DOWN keys will make the rate of change faster than
the TURTLE UP and TURTLE DOWN keys. This is useful during initial setup
where a value may need to be changed significantly. Where necessary, to select
TRUE, use either the TURTLE UP or the RABBIT UP keys, and to select FALSE,
use the TURTLE DOWN or RABBIT DOWN keys.
Use the + or – keys to change integer values in the application software.
To obtain an exact value, press the = key. Key in the required figure and press
ENTER.
NOTE
This may be done only if the figure is within 10% of the existing value.
To save set points at any time, use the SAVE key. This will transfer all new set
point values into the EEPROM memory. The EEPROM retains all set points
when power is removed from the control.
CAUTION—SAVE SET POINTS
To prevent possible damage to the engine resulting from improper control
settings, make sure you save the set points before removing power from the
control. Failure to save the set points before removing power from the
control causes them to revert to the previously saved settings.

Using ServLink with Watch Window
Using Watch Window
Here are brief instructions for using Watch Window in conjunction with ServLink
to view the variables for your 723PLUS control on a PC (personal computer).
These instructions are meant to be introductory only. Full on-line help is available
in each application. It is assumed that you already have ServLink and Watch
Window installed. The default installation location can be found by clicking the
START icon (Microsoft Windows 95 or later) on the main menu bar and then
clicking the PROGRAMS menu item. Look for an icon called WOODWARD
WATCH WINDOW.
1. Make sure that all other programs that may access your computer
communications port are shut down.
2. Get the right cable to talk from your PC to the control (5416-614 will work for
J2 and J3, 5416-870 for J1).
3. Start the ServLink server and open a new file. Select the proper COM port
for your PC, verify that POINT TO POINT communications mode is selected,
and verify that the baud rate matches the baud rate of the 723PLUS. The
default baud rate is 19 200. See the on-line help file if you have been
changing the port settings of your control.
4. Select OK. If everything is working right, you should see an animated picture
of a string of “1”s and “0”s flying from the control to the PC on your screen.
You now have a network definition file whose default name is NET1. You
should save this file as “your filename.NET” (use FILE/SAVE AS). Link this
name to your control part number, as it will work only with that application.
For instance, if the upper level control number is 9907-031, you could save
the file as 9907031.NET. DO NOT DISCONNECT THE SERVER.
5. In the ServLink window you will now have another dialog window titled “your
filename.net”. In this window you will see a ballhead icon and a control
identifier name. Unless you have given the control a serial number (or name)
with the SLSN.EXE program, this name will display as “<unidentified>”.
6. Start the Watch Window application. When Watch Window executes, you will
have a screen displaying three windows entitled Watch Window, Explorer,
and Inspector.
7. The Explorer window will have two groups displayed, SERVICE and
CONFIGURE. Double clicking on either of these will expand them to show
groups of values. Explorer is used only to locate a tunable or monitor value.
In order to change a value or monitor a value, you must drag and drop a
value from the Explorer window into the Inspector window.
8. Once a value is displayed in the Inspector, you can see several blocks of
information. The most important blocks for a tunable value are the FIELD
and VALUE blocks. The FIELD block is used to identify a particular value,
and the VALUE block displays the current value of a variable. There are two
types of values available in Watch Window. One is a monitor value, which is
marked in the INSPECTOR window with a pair of glasses. This means it may
only be looked at. The other value is a read/write value, which is marked with
a pencil. The read/write type may be modified using the up and down arrows
in the value block.

2. Get the right cable to talk from your PC to the control J1 port (5416-870).
3. Start the ServLink server and open a new file. From the dialog window,
select the proper COM port for your PC, select POINT TO POINT
communications mode, and set the baud rate to 19200.
4. Select OK. If everything is working right, you should see an animated picture
of a string of “1”s and “0”s flying from the control to the PC on your screen.
You now have a network definition file whose default name is NET1. You
should save this file. Link this name to your control part number as it will only
work with that application. For instance if the upper level control number is
9907-031, you could save the file as 9907031.NET. DO NOT DISCONNECT
THE SERVER.
5. In the ServLink window you will now have another dialog window titled “your
filename.net”. In this window you will see a ballhead icon and a control
identifier name. Unless you have given the control a serial number (or name)
with the SLSN.EXE program, this name will display as “<unidentified>”.
6. Start the Watch Window program. Under the title bar in the Explorer window
you will find a tab with your network file and the control ID displayed. Right
click this tab to display the pop-up menu, and select LOAD APPLICATION.
This will close the Inspector window and open a new window where you will
enter the name of the file you want to download. Once the filename is
correct, click on the OPEN button. A Warning screen will ask you to make
sure the engine is shut down before downloading. Downloading will proceed
automatically once your accept the message to shut down the engine.

Service Options
Product Service Options
The following factory options are available for servicing Woodward equipment,
based on the standard Woodward Product and Service Warranty (5-01-1205)
that is in effect at the time the product is purchased from Woodward or the
service is performed:
•
Replacement/Exchange (24-hour service)
•
Flat Rate Repair
•
Flat Rate Remanufacture
If you are experiencing problems with installation or unsatisfactory performance
of an installed system, the following options are available:
•
Consult the troubleshooting guide in the manual.
•
Contact Woodward technical assistance (see “How to Contact Woodward”
later in this chapter) and discuss your problem. In most cases, your problem
can be resolved over the phone. If not, you can select which course of
action you wish to pursue based on the available services listed in this
section.
Replacement/Exchange
Replacement/Exchange is a premium program designed for the user who is in
need of immediate service. It allows you to request and receive a like-new
replacement unit in minimum time (usually within 24 hours of the request),
providing a suitable unit is available at the time of the request, thereby
minimizing costly downtime. This is also a flat rate structured program and
includes the full standard Woodward product warranty (Woodward Product and
Service Warranty 5-01-1205).
This option allows you to call in the event of an unexpected outage, or in
advance of a scheduled outage, to request a replacement control unit. If the unit
is available at the time of the call, it can usually be shipped out within 24 hours.
You replace your field control unit with the like-new replacement and return the
field unit to the Woodward facility as explained below (see “Returning Equipment
for Repair” later in this chapter).
Charges for the Replacement/Exchange service are based on a flat rate plus
shipping expenses. You are invoiced the flat rate replacement/exchange charge
plus a core charge at the time the replacement unit is shipped. If the core (field
unit) is returned to Woodward within 60 days, Woodward will issue a credit for
the core charge. [The core charge is the average difference between the flat rate
replacement/exchange charge and the current list price of a new unit.]
Return Shipment Authorization Label. To ensure prompt receipt of the core,
and avoid additional charges, the package must be properly marked. A return
authorization label is included with every Replacement/Exchange unit that leaves
Woodward. The core should be repackaged and the return authorization label
affixed to the outside of the package. Without the authorization label, receipt of
the returned core could be delayed and cause additional charges to be applied.
