OPTI-6100 Installation and Turn-Up Practice
7. Remove the Fan Assembly fuse.
Using the fuse extractor if necessary, remove the Fan Assembly fuse from the bay fuse
panel. If no bay fuse exists for the Fan Assembly, remove the fuse from the rear of the Fan
Assembly instead.
8. Verify that the system Alarm Log menu shows the Fan Assembly alarm.
Check the system Alarm Log menu to verify that an active alarm has appeared which has
the description EXTN input #1 associated with it. Verify that the alarm level matches the
user programmable level assigned during the installation procedure (MINOR is the default
level for this alarm). If no alarm appears, check the alarm wiring between the Fan Assembly
and the OPTI-6100 chassis (wiring details are given in 61184500L1-5).
9. Replace the Fan Assembly fuse that was removed in Step 7.
10. Verify that the system Alarm Log menu shows the alarm has cleared.
The original EXTN input #1 Active Alarm line remains in the Alarm Log, but should no
longer be shown in reverse video. A new line should be present in the Alarm Log indicating
that the Fan Assembly failure alarm has cleared.
11. Clear any inactive alarms.
From the Master Alarms menu, select
to confirm when prompted. This action removes the fan alarms from the Alarm Log.
12. Log out of the OPTI-6100 System.
13. Use to back up through the menu levels until logged out of the system.
