173
Description JPDC-DC 125V Gnd fdbk mag (JD1/JZ2 connector) out of range.
Possible Cause
•
The dc 125 ground feedback magnitude is greater than Gnd_Mag_Trig_Volt.
•
Gnd_Mag_Trig_Volt is set too low.
•
One side of the DC 125 V source voltage is grounded.
Solution
•
Verify that Gnd_Mag_Trig_Volt is set correctly.
•
Check the connections to the specified connector.
•
Verify the grounding of the dc input signals. Refer to the JPDC help documentation.
•
If DC 125V input is not used, this diagnostic alarm can be disabled by setting the InputDiagEnab parameter on the
associated input (DC_125VFdbkMag) to Disabled.
174
Description JPDC-Fuse FU71 or FU72 (J7A connector) is blown or SW7A switched OFF.
Possible Cause
•
The specified switch is turned off and FuseDiag is enabled.
•
The specified fuse is blown.
•
The 125 V dc input is not connected.
Solution
•
If the switch is turned off (output is not used), disable the diagnostic by setting FuseDiag to Disable.
•
If the output is used, verify that the switch is turned on.
•
Replace the fuse.
•
Verify the 125 V dc input connections to the terminal board.
•
If the 125 V dc input is not used, this diagnostic alarm can be disabled by setting the InputDiagEnab parameter on the
associated input (DC_125VFdbkMag) to Disabled.
