Remove the gauge and balance the bridge circuit (P1 = P2) by adjusting the variable orifice (S3) via the adjustment knob. By moving the work piece away from the nozzle (S4) a pressure differential (P1 P2) is created. As soon as the work piece is moved within the detection range of the AirCatch Sensor the back pressure P2 increases.

Note 4) Window comparator mode Since hysteresis is 3 digits, separate P1 and P2 by 7 digits or more. 1 digit is the minimum setting unit (refer to the table above).
One of the preset pressures P1 through P4 is selected by the ON/OFF combination of S1 and S2.

When the work piece comes close to the detection nozzle, the back pressure P2 increases until it is larger than P1 (P2 > P1). Then the switch output turns on to notify that the pressure is below the detection gap.
