Time-outs refer to a preset length of time that a
function is programmed to operate before shutting off
automatically. Certain conditions (filters or freeze) can
cause a function to operate longer, while faults can
cause a function to operate for a shorter length of time.
The system keeps track of time-outs regardless of other
conditions occurring.
