GE Mark VIeS - JPDC-Fuse FU1 T or FU2 T (J1 T Connector) Is Blown or SW1 T Switched off; Input Src Mismatch on JPDC: AC Src Detected at Input Instead DC

179
Description JPDC-Fuse FU1T or FU2T (J1T connector) is blown or SW1T 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.
180
Description Input Src Mismatch on JPDC: AC src detected at input instead DC.
Possible Cause
• The ac voltage has been detected at the 125 V dc input.
Solution
• Verify the 125 V dc input connections. Use a DVM to verify the dc voltage on the input connections.
• Verify that the positive and negative inputs to the 125 V dc bus are connected to the proper terminals. Refer to the JPDC
help documentation.
• 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.
