Description JPDE-[ ] DC Voltage Gnd fdbk mag (JD1/JPS1/JPS2 connector) out of range.
Possible Cause
• The 24/48 V dc ground feedback magnitude is greater than Gnd_Mag_Trig_Volt.
• Gnd_Mag_Trig_Volt is set too low.
• One side of the 24/48 V dc 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 JPDE help documentation.
• If 24/48 VDC input is not used, this diagnostic alarm can be disabled by setting the InputDiagEnab parameter on the
associated input (DC_24VFdbkMag) to Disabled.

Description JPDE-[ ] fuse FU11/FU12 (JS1 connector) is blown or SWS1 switched OFF.
Possible Cause
• The SWS1 is turned off and FuseDiag is enabled.
• The FU11 or FU12 fuse is blown.
• The 24/48 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 24/48 V dc input connections to the terminal board.
• If the 24/48 V dc input is not used, this diagnostic alarm can be disabled by setting the InputDiagEnab parameter on the
associated input (DC_24VFdbkMag) to Disabled.
