Maintenance
3.
If you suspect that a DC or AC fuse is
malfunctioning, go to Section 7.4.3 Fuse
Service and Replacement.
4.
Inspect the buttons on the front panel
keyboard for blockage because of
environmental conditions, such as dirt or
salt build-up (when installed near the
ocean), and clean them, if needed.
CAUTION:
If you apply a cleaning solution to the front panel, do not use a solvent
cleaner. Solvent cleaners may further degrade the buttons on the front panel.
5.
Verify that the protective tape holding the
SD card in place is still functioning
properly. If the adhesive has worn off and
the tape needs to be replaced, contact the
OMNI Help Desk at
+1 281-240-6161.
7.4.2 Change Modules
If you want to add or remove a module, change the installed order of the modules, or simply
replace a damaged card, complete the following instructions.
Take the Flow Computer Out of Service
1.
Follow your local procedures for taking
the flow computer out of service, which
may or may not include:
•
Stopping active flow of the product
in the pipeline system connected
to the flow computer.
•
Ending all batches, either remotely
or manually (Step 2).
•
Saving configuration data
(Steps 3 through 5).
•
Saving reports and archive data
(Steps 6 and 7).
When you have completed your local
procedures, go to Step 8.
If the buttons are too degraded or
cannot be cleaned, the front panel
may need to be replaced.
