(2) Confirm that pressure is being applied. At this time, if the setting dial is fully closed, all LEDs should be off. (3) Turning the setting dial in a plus direction (counterclockwise) will cause the LEDs to turn on in order: Red 1, Red 2, Green 1, Green 2. (4) When the Green 1 LED level meter comes on, output will be switched (5) Apply a clearance gauge to the detection nozzle once more, and confirm that Green 1 has switched on. (6) Hold the setting dial with a finger, and tighten the lock nut with a wrench. Tighten so that the setting dial will not turn. In a bridge circuit as in the figure above, a detection gap is applied to the detection nozzle (S4) while the setting dial S3 is adjusted to balance the pressure applied to the pressure sensor (P1 = P2). The pressure sensor detects the differential pressure generated when the detection nozzle (S4) is released. 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
