CM50 - Complete Reset
Good day to all!
I am currently configuring several CM50s (8 units) for boiler control, with one having some problems.
The analog input 1 and 2 of the controller responds only to the input signal with the range of -35 to -28. I've reconfigured every parameter (scaling, fault detect, etc...) with no success. Other controllers and behave just right with this the only problematic controller. I was thinking of completely resseting the CM50 however, I haven't tried this and have no idea how to do this especially it was not mentioned in the manual.
Is there a way to completely reset the CM50?
From the description given and the fact that the problem is only affecting a single controller I would suggest that you may have a problem with the input circuit itself. Meaning that the it is faulty rather than a configuration issue (Unless you set it up to read that range the only time it would behanve as such is if you have a fault on the input circuit).
You can confirm if this is the case or not by testing the input with a known valid input signal. If this is the case then you would need to have the unit repaired. You can return the unit tot he Factory for warranty repair (If it is within the warranty period).
