GE Mark VIeS - Total Current Varies from Reference Current; Commanded Current Fdbk Error; Suicide Relay Non-Functional

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.
