Time window for faultless operation measured from Triac Command offĆtoĆon transition
Time window for faultless operation measured from Triac Feedback offĆtoĆon transition
Time window for faultless operation measured from Valve Stem feedback offĆtoĆon transition
Time window for faultless operation measured from onĆtoĆoff transition of the Triac Command.
OnĆtoĆoff transitions need not occur sequentially.
Motion Detector transition offĆtoĆon is position dependent, onĆtoĆoff is time dependent
