Configuration Software
NOTE
Where only LED lamps are used, a false lamp-neutral-wire-open
condition may be detected when Lamp Neutral Test is set to On (see
paragraph 7.1.4.9).
To avoid a false error indication, set the Lamp Neutral Test status entry
for each active crossing controller to Off.
4.8
Connecting Power at Initial Cutover
Once the system has booted up, the SSCC IIIi module has internal short circuit protection for
lamp, bell, and gate control outputs. Therefore, at the initial cutover, it is important to boot up
the system before connecting external loads. After external wiring is complete, the connectors
must be applied as instructed in the following CAUTION before applying power to the GCP5000
(GCE) SSCC IIIi module(s).
WARNING
DURING THE SSCC BOOT-UP PROCESS AND AFTER ALL WIRING
IS CONNECTED:
THE CROSSING GATES WILL BE DOWN WITH CROSSING
LAMPS FLASHING AND BELLS RINGING.
A80405 MODULE(S) WILL NOT BE RESPONSIVE TO CROSSING
CONTROL INPUT FROM THE GCP5000 (GCE).
TAKE ADEQUATE PRECAUTIONS TO WARN ANY PEDESTRIANS,
PERSONNEL, TRAINS, AND VEHICLES IN THE AREA UNTIL
PROPER SYSTEM OPERATION IS VERIFIED.
CAUTION
THE WIRING AND CONNECTORS MUST BE APPLIED IN THE
FOLLOWING SEQUENCE TO AVOID DAMAGE:
1. OPEN THE LAMP, GATE GC CONTROL, GP INPUTS, GD INPUTS,
AND BELL CIRCUITS AT THE SURGE PANEL(S).
2. VERIFY POLARITY ON POWER CONNECTOR(S).
3. CONNECT THE SCREW-LOCK POWER CONNECTOR FOR EACH SSCC
IIIi MODULE AND LOCK BY TIGHTENING SCREWS.
4. WAIT APPROXIMATELY 40 SECONDS FOR SSCC IIIi
MODULE(S) TO
BOOT UP.
5. CONNECT THE GC/BELL AND GP/GD CAGE–CLAMP CONNECTORS FOR
THE APPROPRIATE SSCC IIIi.
6. CLOSE THE LAMP, GATE CONTROL, GP/GD INPUTS, AND BELL
CIRCUITS ON THE SURGE PANEL(S).
