problems you have.
Cleaning System Problems Indicated by Error Messages
Problems that display errors are usually easily corrected and happen for a definite reason.
Usually a stuck or out-of-adjustment switch or possible loose or damaged wires will cause
most problems.
If an input fails to go off completely and still displays a dim light, the PLC will still consider
that as a good input so look closely.
This error normally happens when Duster Input 0CH 10 fails to open, meaning the input light
does not turn off.
