I know theres a few on here who do machinery safety systems.... more a curiosity question than anything... are non latching EM stops every allowed, and if so, under what conditions?
I always thought they had to be of a latching type, but it seems not all that are fitted are. When working near those industrial speed doors I've got in the habbit of popping the EM stop in so the door can't move, but came across one that was a non-latching EM stop. Surely it cannot be right, that after the door has been stopped on the EM stop, that it can be be commanded to move again from the remote up/down controls without having to go to the EM stop and unlatch it?
