I think you are working.
I have the ref1 and ref 0 crystal unit and when operational thats the way
the LEDs work.
On my unit the system locks in 15-30 minutes from a cold start.

On start up the LEDs should step.
Then the top 2 should turn on. No gps and fault
15 minutes later fault of green on
2-5 minutes later no gps off.
The ref zero aligns to the Ref1. If Ref 0 fails 1 will turn green.
Good luck
