SECTION 7 - REPAIR/REPLACEMENT PROCEDURES
INTRODUCTION
This section explains the replacement procedures for the Plant
Loop to Computer Interface (INPCI02). There are no special
tools required to replace an interface module.
NOTE: Always use the Bailey Field Static Kit (P/N 1948385A1)
when working with the interface modules. This kit connects the static
dissipative work surface and technician to the same ground point.
MODULE REPAIR/REPLACEMENT
If you determine an interface module is faulty, replace it with a
new one.
DO NOT
try to repair the module; replacing compo-
nents may affect the module performance. You can remove the
module while system power is supplied. To replace a module:
1. Push and turn the two front panel captive retaining latches
one half turn to unlatch the module. It is unlatched when the
slots on the latches are vertical and the open end of the slots
face away from the module.
2. Gently slide the module out of the MMU.
3. Configure the replacement module switch and jumper set-
tings. Ensure they are set the same as the original module.
4. In the same slot assignment as the original module, align
the replacement module with the plastic guide rails in the
MMU; gently slide it in until the front panel is flush with the
top and bottom of the MMU frame.
5. Push and turn the two captive retaining latches on the
module faceplate one half turn to the latched position. It is
latched when the slots on the latches are vertical and the open
ends face the center of the module.
6. Return to normal operation.
