 Actuation (1 act & 2 act) – The actuation parameter determines whether the
relays will react to increasing or decreasing pressure. This parameter also
affects the status of the LED indicators on the front of the gauge. The above
graphs illustrate the differences.
 Direct – The relays turn on with increasing pressure
 Reverse – The relays turn on with decreasing pressure
