170-171
Description Input Src Mismatch on JPDF-[ ]: 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 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 JPDF
help documentation.
172
Description JPDC-DC 125V fdbk mag (JD1/JZ2 connector) out of range.
Possible Cause
• The 125 V dc input is less than DC_125v_Trig_Volt.
• DC_125v_Trig_Volt is set too high.
• The 125 V dc source voltage is out of range.
• The 125 V dc input is not connected.
Solution
• Verify that DC_125v_Trig_Volt is set correctly.
• If fed from the dc battery input, check the connections to JD1 and TB1.
• If fed from DACA, check the connections to JZ2.
• Verify the grounding of dc input signals. 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.
