GE Mark VIeS - JPDG DC 24 V Voltage GND Fdbk Mag (JPS1;JPS2 Connector) out of Range; JPDG DC 24 V Voltage Dry Contact Input (P4 Connector) Not OK; JPDG Fuse FU10;FU11 (JFA Connector) Is Blown

209
Description JPDG DC 24V Voltage GND fdbk mag (JPS1/JPS2 connector) out of range
Possible Cause
• The 24/48 V dc ground feedback magnitude is greater than the Gnd_Mag_Trig_Volt.
• The Gnd_Mag_Trig_Volt is set too low.
• Only one side of the 24/48 V dc source voltage is grounded.
Solution
• Verify that the Gnd_Mag_Trig_Volt is set correctly.
• Check the connections to the specified connector.
• Check the grounding of the dc input signals.
• If 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.
210 – 211
Description JPDG DC 24V Voltage dry contact input [ ] (P4 connector) not OK
Possible Cause
• The power supply contact is open. The power supply is not operating normally.
• The power supply dry contact feedback is not connected to the terminal board P4 connector.
Solution
• Verify the status of the power supply contact, and that the power supply is operating correctly.
• Check the connections between the power supply and the P4 connector on the JPDG.
• 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.
212
Description JPDG fuse FU10/FU11 (JFA connector) is blown
Possible Cause The FU10 or FU11 fuse is blown.
Solution
• Replace the fuse.
• 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.
