Can this switch be set up with a manual reset or do you have a switch with this ability, I am looking for the switch to shut off power when pressure rises to 180 PSIG. The switch would be used in Anhydrous Ammonia service and located outdoors.
Thank you for your inquiry, The PSW-243 does not have the ability to do a manual reset, this unit is designed for harsh environments (Class I, Division 2).
