Ppda Invalid Combination: More Than 2 Jpdm Boards Present; Ppda Invalid Combination: Both Jpds And Jpdm Terminal Boards Present; Jpde 24/48 Vdc Magnitude (Jd1/Jps1/Jps2 Connector) Out Of Range - GE Mark VIeS System Manual

146
Description PPDA Invalid Combination: More than 2 JPDM boards present.
Possible Cause PPDA allows up to two JPDM boards to be connected as part of the Power Distribution module. The
PPDA has detected more than two JPDM boards connected through ribbon cables to the PDM.
Solution
• Verify that only one or two JPDM terminal boards are connected to the PDM through ribbon cables.
• Reboot the PPDA after the hardware connections are corrected.
147
Description PPDA Invalid Combination: Both JPDS and JPDM Terminal boards present.
Possible Cause PPDA does not allow JPDS and JPDM terminal boards to be mixed. The PPDA has detected both JPDS
and JPDM terminal boards connected through ribbon cables to the PDM.
Solution
• Verify that there are only JPDS or JPDM boards present, but not both.
• Verify that the ToolboxST configuration matches the hardware configuration.
• Reboot the PPDA after the hardware connections are corrected.

Description JPDE-[ ] 24/48 VDC magnitude (JD1/JPS1/JPS2 connector) out of range.
Possible Cause
• The 24/48 V dc input is less than DC_24v_Trig_Volt.
• DC_24v_Trig_Volt is set too high.
• The 24/48 V dc source voltage is out of range.
• The 24/48 V dc input is not connected.
Solution
• Verify that DC_24v_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.
