Note: ① Is the range of medium pressure of high pressure port.
② In practice, the short-lived pressure peaks of the medium in the two pressure ports should not exceed this value.
Adjustment Of The Set Value

Single-pole, double-throw microswitch procedure:
Terminals 1-3 are switched on when the pressure rises to the upper switching value.
Terminals 1-2 are disconnected when the pressure rises to the upper switching value.
