Description JPDF-[ ] DC 125V Ground magnitude (JD1/JZ2/JZ3 connector) out of range
Possible Cause
•
The 125 V 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 JPDF 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.

Description JPDF-[ ] fuse FU1R or FU2R (J1R connector) is blown or SW1R switched OFF
Possible Cause
•
The SW1R is turned off and FuseDiag is enabled.
•
The FU1R or FU2R fuse is blown.
•
The 125V 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.
