Hand/Trip switch failure detection
Hand/Trip switch failure detection
(OP)
HI
Have a question on field hand/trip switches. Their failure in most of cases activates a trip function. My question is, how does the safety system know/detect that switch is faulty and how is it different between normally open and normally close switches?
Thank you
