To head off any confusion, I'm not talking about lock out tag out here, rather key lockable door handles on panel doors.
Bubba called me in the middle of the night for a sticky PLC relay output and when I got to the site I couldn't open the control panel door because it was key locked. It took half an hour to find out who had the key, and another half hour for him to come in with his key and unlock the panel door, all for a five minute module swap.
He explained the reason for locking the panel door, and in this case I completely agree, I won't elaborate the reason for IP reasons, but its a damn good reason.
Most of our panels are not locked aside from the disconnect interlock, however after the lost production overnight its obvious that we need a system for managing a few control panel lock keys.
Do any of you have a system that you would care to share"
