SECTION 4 - REPAIR/REPLACEMENT PROCEDURES
INTRODUCTION
This section explains the replacement procedures for the con-
troller/station termination module.
MODULE REPLACEMENT PROCEDURES
If an ICS module is faulty, replace it with a new one. To replace
an ICS termination module:
1. Turn off power to the PCU containing the defective ICS
module.
2. Remove the front cover from the defective ICS module.
3. Label and remove all wiring and cables from the defective
ICS module.
4. Remove the defective ICS module from the termination
mounting unit.
5. Verify that the 4.0 amp/250 volt fuse is installed in fuse
clip F1 of the replacement ICS module. If not already installed,
insert the fuse into fuse clip F1.
6. Set the switches on the replacement ICS module according
to the installation instructions.
7. Connect all wiring and cables removed in Step 3 to the
replacement ICS module.
8. Verify proper wiring and cable connections to the replace-
ment ICS module.
9. Install the replacement ICS module into the termination
mounting unit.
CAUTION
It is strongly recommended that
all
power (cabinet, I/O, etc.) be
turned off before doing any termination module wiring. Failure
to do so could result in equipment damage. Do not apply
power until all wire connections are verified.
ATTENTION
Il est fortement recommandé que
toutes
les alimentations
(armoire, E/S, etc.) soient coupées avant d'effectuer quelque
raccord que ce soit sur un carte de raccordement. Un manque-
ment à ces instructions pourrait causer des dommage à
l'équipement. Ne pas rebrancher les alimentations avant
d'avoir vérìfié tous les raccordements.
