70-71
Description Output [ ] Total current varies from reference current
Possible Cause The difference between the commanded output current and total feedback is greater than TMR_
SuicLimit.
•
Field wiring problem
•
Open-circuit on output or total loop resistance is too high
•
Command is beyond the range of the output.
Solution
•
Check field wiring and device.
•
Verify that the value of TMR_SuicLimit is set correctly.
•
Verify that commanded output is within output range.
74-75
Description Output [ ] commanded current fdbk error
Possible Cause The difference between the commanded output current and current feedback on the terminal board is
greater than D/A_ErrLimit (%).
•
Open-circuit on output
•
Terminal board output jumper (JPO) setting is incorrect (for output 1).
•
Command is beyond the range of the output.
Solution
•
Check the field wiring and device.
•
Check the JPO jumper setting on the terminal board.
•
Verify that the value of D/A_ErrLimit is set correctly.
•
Verify that the commanded output is within output range.
•
Replace the I/O pack.
82-83
Description Output [ ] Suicide relay non-functional
Possible Cause The analog output suicide relay command doesn't match the feedback.
•
Relay failure on the acquisition board.
•
Hardware failure
Solution Replace the I/O pack.
