Re: [PSUBS-MAILIST] Waterproof controls
Hi Folks
I have seen lockout boxes for valves that when opened trip an alarm,
this arrangement could be reconfigured so that when the lockout box is
opened a switch from the battery bank could be tripped, any folks out
there in the oil or marine industry may have seen these lockout boxes.
Regards, Garry
