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.

Normal primary pressure Drop of primary pressure Increase of primary pressure Pressure P1 P2 Time Switch output 1, 2 ON OFF The correction value is not stored on the EEPROM. When auto shift is used: When the primary pressure changes, set the auto shift function to Lo.
The pressure set by a compact regulator valve or an electro-pneumatic regulator is supplied to the P1 (external pilot) port of the VEX, which controls the large amount of pressure.
When the pressure is released to P1 (external pilot), the A (output) port side air is exhausted from the R (exhaust) port.
Fixed orifice and variable throttle are available as a throttle for adjusting the pressure increase. (1, 1.5, 2) Output Pressure (P2) vs Time Graph Output P2 P1 P2 reaches half of P1, and then the main valve of the soft start-up valve turns on.
