RM4 LED Signals Rail
Testing
If testing before installation, be sure to use a constant power source rated 10V / 2 A minimum to ensure proper
operation of the LED signal. NOTE: Failure to do so will activate the light-out safety detection feature of the LED signal
and disable the lamp's operation.
Installation Steps
NOTE: Failure to properly follow these instructions may cause signal to malfunction.
1
Existing signal head in the field: Remove lens and
incandescent bulb assembly from housing.
Existing in-line rheostat in the field: Set rheostat (variable
2
resistor) to zero (0) or remove completely.
3
Voltage settings: Check the label on the back of the LED
module to ensure the voltage corresponds to the system
voltage. The recommended voltage at the signal head is 10V.
4
Wiring: For wire installation, please follow guidelines shown
below.
5
Insertion of LED module into signal head: Insert the LED
module into lens slot and tighten metal tabs, or insert LED
