Hey guys, hoping someone can help me out. I have a 400a that has redundant ciomrl issues. I have had Schindler replace one once and I have replaced another since. Basically the directional arrows haven't worked since schindler replaced the ciomrl initially, along with a few other functions. On the ciomrl the channel a light is green but channel b is red??? In the bigger picture the ciomrl shuts down the car with estl faults, jhc1 even though the stop switch is made up, and various other random faults. I have eliminated the eblon board as an issue. It's almost similar to the hall call boards were they easily become corrupted. New ciomrl solves running problem but not directional arrows, fire audible and other functions. Any insights or recommendations would be appreciated. I have little info on these units. Thanks.
