Setting Value Adjustment of fan pressure switch

1). Use the wrench to clamp the six square plane of controller, to screw the pressure interface into pressure interface of the pressure check table.

2). Open the cover plate, to connect the one end of cable to the wiring terminal 1-3, another end connected with universal meter.

3). To add the pressure value into necessary value, adjust the screw with counterclockwise rotation. Make the setting value from large to small, till the switch contacts switch the value in the required pressure value. And change the pressure value back and forth on required pressure value, so that to check the switch value of contacts is the needed pressure value.

4). Closed the cover plate

Single pole double throw micro switch process.

Connect terminal 1-3, to put through until pressure raised to upper switching value.

Connect terminal 1-2, to switch off until pressure raised to upper switching value
