SECTION 7 - REPAIR/REPLACEMENT PROCEDURES
INTRODUCTION
MODULE REPLACEMENT PROCEDURE
I-E96-610A
Repair procedures are limited to module replacement. If an
INFI-NET to computer interface module fails, remove and
replace it with another. Verify that the replacement module
dipswitch and jumper settings are the same as those of the
failed module.
NOTE: Do not remove INICT01 and INICT03 modules under power
unless the stop (INICT01) or stop/reset (INICT03) pushbutton has
been depressed and module operation has been halted.
Follow Steps 1 through 7 to replace computer interface mod-
ules. Observe the steps listed in the
tion of this manual when handling computer interface
modules.
1. Turn the 2 latching screws on the defective computer inter-
face module ½ turn either way to release them. In the case of
the INICI03 INFI-NET to Computer Interface, the INICT03 and
IMMPI01 or IMMPI02 modules are connected by cable and
must be disconnected.
2. Grasp the screws and slide out the module or modules.
3. If necessary, disconnect the cable connecting the modules
and remove only the defective module.
4. Set any dipswitches and jumpers on the replacement mod-
ule to match the settings of the removed module.
5. If necessary, connect the replacement module with any
interconnecting modules.
6. Hold the module or modules by the faceplate and slide
them into their assigned slots; push until the rear edges of the
modules are firmly seated in the backplane connectors.
7. Turn the 2 latching screws on the module or modules ½
turn to lock the modules in place. Modules are locked into the
module mounting unit when the open end of the slots on the
latching screws face the center of the module faceplate.
