Troubleshooting issues and recommended actions (continued)Table C-2:
Issue Recommended actions
Connected communication line
to the flow computer but no sig-
nal is received
Check for loose connections at the flow meter and the flow
computer. Check the CPU Module, Field Connection board and
the Power Supply wiring. Make sure the terminal block wiring
and connectors are making good contact.
Communicating with meter but
all chords display failures
Verify that the resistance of transducers is within Specification
(1-2 Ώ) . Check the Acquisition board. Check the interconnect
cables between the base enclosure and the transmitter enclo-
sure.
Chord is not indicating Check the resistance of the failed transducer. If Chord A is not
indicating, change the transducer cables from Chord D to
chord A. If Chord D then fails, the transducers are bad on
Chord A. The same test procedure can be accomplished by
swapping Chords B and C if a chord fails in either chord. Note
that the outside chord cables cannot be exchanged with inner
chord cables.
