Product Description
The LumenTrac LT1 system continuously monitors the output of a light source at the fixture level and notifies the user when the source
has reached 70% of its initial output (referred to as "End-of-Life" or E.O.L.).
The LumenTrac LT1 controller can be installed inside of or remote from an LED luminaire. AC power and dimming control signals pass
through the LT1 controller to the LED power supply, allowing the LT1 to switch the light source on and off and enable or disable
dimming as needed for measurements.
When the light source’s output falls below 70% of its initial value, the indicator LED will turn on and remain on while the luminaire is
powered. Additionally, the LT1 controller’s contact closure output will energize, closing the NO contact and opening the NC
contact. The contact closure connections allow the LT1 system to interface with a building automation system for remote monitoring
of the connected luminaire’s status.
Date: 7/31/2013
The LumenTrac LT1 sensor must be mounted inside the optical housing of a luminaire. The sensor does not need to be aimed directly
at the light source, except in luminaires with a fully transparent lens.

A suitable enclosure must be provided for the controller. This may be the driver compartment of a light fixture.
The controller is suitable for dry locations only.
The "GND" terminal MUST be connected to earth ground.
Each group of inputs/outputs are fully isolated from each other. Any field wiring to the controller classified as electric power
wiring must be separated from any wiring classified as low-voltage wiring.
A.
The AC input and output terminals will always be wired to an AC power circuit.
B.
The Sensor input connection will always be a low-voltage Class 2 circuit.
C.
The dimming and auxiliary circuits may be wired as AC power or as low-voltage circuits, depending on the application.
Power connections
A.
Connect branch circuit to AC Line IN and AC Neutral terminals.
B.
Connect fixture power supply AC input leads to AC Line OUT and AC Neutral terminals.
Dimming connections
A.
Connect dimming control (if present) circuit to Dim1 IN and Dim2 IN terminals.
B.
Connect fixture power supply dimming control circuit to Dim1 OUT and Dim2 OUT terminals.
C.
NOTE: if the fixture power supply is to be connected to a dimming control, the control signals MUST be connected
through the controller's DIM terminals.
D.
NOTE: do not use "phase-cut" or "dimmed-hot" dimming power supplies with the LumenTrac controller.
Auxiliary connections
A.
Connect contact closure supply voltage from building automation system or indicator panel(if present)to Aux Com
terminal.
B.
Connect contact closure input of building automation system (if present) to Aux NC or Aux NO terminal.

The sensor board should be mounted inside the optical chamber of the fixture.
The sensor board must be installed so that the light sensor receives light from the LEDs directly, through internal reflection, or a
combination of the two. Best results will be achieved when most of the light hitting the sensor is reflected off the interior of the
fixture before hitting the sensor.
A.
If the sensor is getting too much or too little light during initialization, the controller will repeatedly perform initialiaztion
tests (cycling power to the fixture on and off) until the amount of light on the sensor is within the acceptable range.
B.
If the sensor is getting too little light during a normal test, the indicator LED will flash on and off to indicate the problem.
See the section on Indicator/Warning Codes for more information.
The sensor board may be secured using fasteners through the 2 holes provided, or using double-sided adhesive tape.
It is recommended that the bottom of the sensor board be insulated from earth ground.
Affix the included label "REPLACE SOURCE WHEN RED LET IS ON CONTINOUS" in an area near the sensor head.

6-conductor jacketed cable suitable for the installation should be used.
A.
For most applications, standard 6-conductor cable will perform acceptably.
B.
Using 6-conductor twisted-pair cable (3 pairs of 2 conductors) will result in better performance. LED Out and Ground
should share one pair, Sensor In and Ground should share another pair, and V+ Out and Button In should share the last
pair.
C.
If high levels of electromagnetic interference will be present, use shielded 6-conductor twisted-pair cable with a
separate drain wire (shield ground). The shield ground should be connected to earth ground at the controller end of
the cable.
Both the controller and sensor head have sockets that mate with PTPM-series connectors from Phoenix Contact. See the table
below for appropriate part numbers and wire sizes.
A.
Wires are terminated inside the connectors by sliding each conductor into the appropriate slot in the connector, then
clamping the wire holder down to the connector housing using a pliers or similar tool. The connectors are insulationdisplacement type and do not require the wires to be stripped before insertion.

Initialization
4.
5.
6.
It is critical that all diffusers, lenses, housings, shields, etc. be in place during the entire initialization process.
Initialization should be done as soon as possible after fixtures are installed.
When the fixture is powered, pushing the reset button will trigger an initialization the next time power is turned off and back on.
A.
The reset button can be pushed again to cancel initialization.
In switched mode, the system will store the baseline light output immediately when power is turned on. The controller will take
sensor measurements both with the fixture power off and on and break the dimming circuit as needed during the
measurement. After the baseline is stored, the dimming circuit will be connected for normal operation.
In 30-day mode, the controller will turn the fixture on for 3 hours before measuring the output. After 3 hours, the controller will
turn the power to the fixture off and on and break the dimming circuit as needed during the measurement, then leave the
power on with the dimming circuit closed for normal operation after the baseline is stored.
After initialization, the status LED will blink once and the baseline light output of the fixture will be stored in memory in the
controller. The baseline output is kept in memory even when the fixture and controller are turned off.
Operation

Rev: 2
2.
Switched mode - for fixtures that are normally switched on and off periodically
A.
Every time the fixture is switched on, the system measures the output of the LEDs and compares it to the baseline value
stored in memory during initialization.
B.
The controller will measure the ambient light with power to the LEDs off, switch on power to the LEDs with the dimming
contacts open, measure the total light, and calculate the current light output.
C.
After each measurement and test, the dimming contacts are closed to allow normal dimming of the light source.
D.
A switched-mode test is completed in approximately 1 second. The indicator LED will blink once to indicate a
successful test.
30-day mode - for fixtures that are left on continously for at least 30 days at a time
A.
When the fixture is turned on, a timer in the controller will begin counting up to 30 days from zero.
B.
When 30 days have passed, the controller will switch off power, measure the ambient light, switch on power to the
LEDs with the dimming contacts open, measure the total light, and calculate the current light output.
C.
After the test is complete, the dimming contacts will close to allow normal dimming.
D.
A 30-day mode test is completed in approximately 3 seconds. The indicator LED will blink once to indicate a successful
test.
E.
If power to the fixture is turned off, the 30-day timer will re-start at zero the next time power is turned on.

Light Source End-of-Life Detection
2.
3.
4.
Three consecutive measurements below 70% of the baseline light output must be taken before the system will indicate end-oflife.
When LED end-of-life is detected:
A.
The indicator LED on the sensor head will turn on and remain on as long as the fixture is powered.
B.
The auxiliary output relay will energize, connecting the NO contact to the COM contact and disconnecting the NC
contact from COM.
The light source will remain powered and dimming will operate normally even if end-of-life has been detected.
At any time, if a measurement above 70% of the baseline is taken, the end-of-life warning will be cancelled. It is not necessary
to re-initialize the fixture.
A.
This may be caused by conditions such as removal of foreign matter from the fixture, cleaning the interior of the fixture
after heavy dirt build-up, or replacement of a failed driver or power supply.
