Hello,
We are getting a fault listed as Car Fault 1123. Car Top Inspection Node A CAN Communication is Offline. We don't have the correct job Print. We see (2) L24 boards not sure if this could be a problem? Any ideas?

Also, you can run elevator up on inspection. The elevator runs fine down direction. As soon as you try the up direction run monitor error 1123. On full automatic....Valve Issue?

1123 is up run stalled. If it runs up on inspection but not auto make sure your fast valve coil relays are picking and those are picking your up fast solenoid. Also increase Z35 to give you more allowance before the run monitor.
