INTRODUCTION
This section explains the replacement procedures for a Quick
Response Controller (IMQRC01). There are no special tools
required to replace these modules.
MODULE REPAIR/REPLACEMENT PROCEDURES
If a QRC is faulty, replace it with a new one. DO NOT try to
repair the module. Replacing components may affect the mod-
ule performance and certification.
The module can be removed while system power is supplied. To
replace a module:
1. Push and turn the two front panel captive retaining screws
one half turn to unlatch the module. It is unlatched when the
slots on the screws are vertical and the open end of the slots
face away from the module.
2. Slide the module out of the MMU.
3. Configure the replacement module switches and jumper
settings. Ensure they are the same as the original module.
4. In the same slot assignment as the original module, align
the replacement module with the guide rails in the MMU; 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 screws on the
module faceplate one half turn to the latched position. It is
latched when the slots on the screws are vertical and the open
ends face the center of the module.
6. Configure the replacement module default settings and
control strategy. Ensure they are the same as the original
module.
WARNING
If the module is located in a Class I Division 2 hazardous envi-
ronment, take the necessary precautions before and during
module replacement. Fire or explosion may result.
