GCP5000 (GCE) INSTALLATION, CALIBRATION AND SYSTEM OPERATIONAL CHECK
__________________________________________________________________________________________
Step 7
Finishing Step 8 completes the GCP5000 (GCE) operational checks/tests. Proceed to SSCC IIIi
Operational Tests for SSCC calibration and operational checks/tests.
6.4.2.1 SSCC IIIi Operational Tests
After the system has been programmed, GCP calibrated and the lamp voltages have been
adjusted, tests must be performed to verify the operation of the SSCC before placing the system
in service. In addition to the operational tests required by the maintaining railroad, the SSCC
operation should be further tested and verified as described in the SSCC Operational Tests
procedure.
AFTER INITIAL PROGRAMMING OR SUBSEQUENT PROGRAMMING,

PERFORMED TO VERIFY PROPER OPERATION OF THE SSCC IIIi
PRIOR TO PLACING THE SYSTEM IN SERVICE.
While in Test Mode, if a train approaches (XR input logic de-energizes,)
the test is canceled and the crossing activates normally. When the train
departs, the system remains in normal operation.
If advance preemption is used, the preemption output and warning devices will operate as
follows for the indicated method of activation:
•
For a train move:
Preemption Output de-energizes at the preempt warning time.
Activation of the warning devices will be delayed until the Advance Preempt Timer times
out.
•
Advance Preempt Input de-energized:
Preemption Output de-energizes
Activation of the warning devices will be delayed until the Advance Preempt Timer times
out.
•
AND 1 Enable Input de-energized:
Preemption Output de-energizes
Activation of the warning devices occurs simultaneously (no advance preempt time).

Version: B.1
Island detection:
When used, observe the Island symbol on tracks on the Main
Status display.
Place a 0.06 ohm or 0.2 ohm shunt (per railroad or agency
requirements) on island track wires
Island show OCC
Observe the Island LED on the PSO module as the shunt is removed
and while Island Pickup Delay is timing
Island LED is flashing:
After the island pickup delay time expires, the island
LED on the PSO module is illuminated steady.
The Island symbol on the Display shows CLR, and warning devices
are deactivated.
