Version: B.1
6.3.2 Recalibration/Reprogramming Requirements Due to Track Equipment Changes
Table 6-3 indicates the recalibration required when any changes are made to the existing track
equipment. For example, when an existing Tuned Insulated Joint Coupler, 7A422-f in an
installation is replaced or moved to a different location, the receiver must be recalibrated, but
not the island.
WARNING
FAILURE TO RECALIBRATE OR RESET THE RECEIVER THRESHOLD
CAN RESULT IN IMPROPER SYSTEM OPERATION.

GCP5000 (GCE) Operational Checks
Before placing a system in service, tests must be performed to verify proper system operation
and I/O wiring. Proceed to the next step if a feature is not used.
WARNING
AFTER INITIAL PROGRAMMING OR PROGRAMMING CHANGES,
TESTS MUST BE PERFORMED TO VERIFY THE PROPER OPERATION
OF THE GCP PRIOR TO PLACING THE SYSTEM IN SERVICE.
WARNING
AFTER PROGRAM CHANGES, CHECK:
THAT THE OCCN MATCHES THAT ON THE REVISED SITE PLANS.
THE CONFIGURATION SHOWN IN THE CONFIGURATION REPORT
MATCHES THE REVISED SITE PLANS.
