EST3 Groundfault

[joes66]

Hello. I have an active ground fault P:01 C:00 D:602. Its the card 00 throwing me off. Is it coming from the 3cpu or the power supply? How would i determine which one has the ground fault?

it is not coming from a loop controller, possible ground on amplifier, 24vdc output form a power supply or battery wires.
disconnected all wires until ground fault clears then connect one at a time to determine which one has ground.

Removed wires from amplifiers and speakers and battery. Ground fault stil present. Anything else i can look at or try?

reboot with all wires removed, if ground fault is persistent try replacing power supply 3-PPS/M
