SECTION 4 - REPAIR/REPLACEMENT PROCEDURES
INTRODUCTION
This section explains the replacement procedures for the
NIMP01 and NIMP02 Multi-Function Processor Termination
Modules (IMP).
FUSE REPLACEMENT
If the fuse (F1) opens, replace it with a fuse having an equiva-
lent rating. Table
4-1 describes the fuse and lists its Bailey part
number. To replace a fuse:
1. Turn off power to the cabinet.
2. Remove the blown fuse from its holder (F1).
3. Replace the blown fuse with a 1.0 A/250 VDC fuse.
4. Turn on power to the cabinet.
MODULE REPLACEMENT PROCEDURES
If you determine that the IMP termination module is faulty,
replace it with a new one.
Do not try to repair the module;
replacing components may affect the module performance and
certification. When replacing a termination module, observe
the special handling guidelines listed in
Section 2 .
NOTES:
1.
Turn off power to the field devices before removing the
RS-232-C cables from the IMP termination module.
2. When replacing a termination module, verify that the fuse is
installed and the jumper settings on the replacement termination
module are the same as the failed termination module.
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 connections are verified.
ATTENTION
II est fortement recommand, que toutes les alimentations (arm-
oire, E/S, etc.) soient coupées avant d'effectuer quelque rac-
cord que ce soit sur un carte de raccordement. Un
manquement à ces instructions pourrait causer des dommage
à l'équipement. Ne pas rebrancher les alimentations avant
d'avoir vérifié tous les raccordements.
