6.12 Shutdown Timer for K1
The shutdown timer is used in the operation mode and allows K1 to remain on for the duration of this setting
when enclosure pressure drops below the minimum setting of P1. If the pressure goes above P1 during the
countdown, the timer is reset. If the pressure remains below P1 for the duration of the countdown, K1 will
shut off.
The shutdown timer is effective only for Program 3, in which K1 de-energizes when enclosure pressure is
below P1. The other programs allow power to the enclosure to remain on when pressure is below P1, with an
alarm generated to the operator.
The default value is 0 seconds. The range is 0 to 300 seconds.
