Thank you, everyone, for the prompt replies. I raised this question because we have the maintenance of a 26 floor traction elevator. One of our technicians informed me that despite the controller being in inspection mode in the machine room, it was still operating at normal speed. I found this hard to believe until I personally inspected the controller. I discovered a faulty INSP/NORM switch on the main board. This sounded like a serious safety issue in the controller to me, and made me to delve into the code and ascertain that the type of switch being used for INSP/NORM is not in accordance with the specifications outlined in the code.
I believed that sharing this information could also be beneficial for you as well and maybe help preventing injury and death.
