Page 33: High Pressure Switch Operation
High Pressure Switch Operation The control has a built-in lockout system that allows the unit to have the high pressure switch trip up to two times in 1 hour and only encounter a “soft” lockout. A “soft” lockout shuts the compressor off and waits for the pressure switch to reset, which at that point then allows the compressor to be restarted as long as the 5-minute short cycle timer has run out. -
