Warning
Read the instructions in their entirety before starting any repair activities.
When it is absolutely mandatory that the door interlock be bypassed to trace a fault or correct a malfunction,
authorized maintenance personnel may perform the bypass by pulling the interlock out toward you for the specific
test to be made. Immediately after completing the test, the interlock shall be restored to working condition.
When the current sensing option is present, turning the rotary switch S2 to OFF does not remove power to the
flashers unless both the ON/OFF switch S1 is turned to OFF and the CCR connected to the isolation transformer is also
turned off.
Table 9: REIL Troubleshooting Procedures
Problem Possible Cause Solution
1. No flashing in
either individual
control cabinets
No input power
L-849V: Check voltage at terminal block TB1 terminals 14 and 15.
L-849I: Verify input current is present at TB1 terminals 14 and 15.
Blown fuse F1 or F2 in Primary Cabinet Replace fuse. Determine why fuse has blown and repair.
L-849V: External circuit breaker trips each
time it is turned on
Lightning arrestor V1 or V2 is shorted. Replace lightning arrestor.
No power to Flasher Control Board. Fuse F3 blown. Replace F3.
2. One individual
control cabinet
flashes, but the other
one does not
Secondary unit is turned off.
Blown F1, F2 or F3 fuse in non-flashing unit.
Turn Secondary unit ON
Replace fuse. Determine why fuse has blown and repair.
LED Optical Assembly defective. Replace Optical Assembly.
Current driven REIL- Failed Power Supply
PS5.
Verify that 240VDC is present at PS5 terminals E5 (+) to
E6 (-). Replace power supply if correct voltage is not present.
Flasher Control PCB failed. Replace PCB.
Loose external wire connection.
With the power off and using an ohmmeter, check continuity of each
wire.
3. Light flashes
intermittently
Flasher Control PCB failing. Replace Flasher Control PCB.
LED Optical Assembly failing Replace the assembly.
4. Operates in Local
control but not In
Remote
Fuse F4 blown. No 120VDC is present for
remote control signals.
Replace F4. Determine reason for short in external remote control
circuitry.
5. Light output is
dimmer in one of the
Flashers.
One of the LED Power Supply PCBs, PS1, PS2
or PS3 has failed.
On the suspected failing board, verify presence of 55VDC ±
5VDC at J2 + to -.
Replace board if voltage is incorrect.
