I've got a M94A that I installed and its been running for weeks. This weekend they changed out a pallet and the thing never came back on. Checked voltages for the GS, ES, AS compared to print, all good. LEDs on front of safety card all good. Replaced the safety card no change. As soon as I enable motors the Red ERR light pops up instantly and a second later the motors drop out. The card is timing out on something, but what? any ideas?
20009: Run chain status fault
Two channel status conflict.
Check:
Check the leds on the system board
when the red ERR led is lit to see
where the fault is situated.

20020: Run chain status timeout
Two channel status timeout.
The acknowledgement for a two channel
run chain status change was not
received within the expected time.
