How to adjust the pressure switch?

1, short press (on/off) the operation key, turn off the operation indicator light, and the pressure control system will turn off. Set the control upper/lower limit. Press the setting key 1 time to set the value through (▲) (▼). After setting the lower limit, press the set key briefly to enter the upper limit setting. The setting method is the same as above.

2. After the setting is completed, press the set key, and the set value will be automatically saved in the computer chip (after the parameter is modified, the current parameter setting will be automatically saved without pressing the key within 5 seconds). Press (on/off) the running key again (the corresponding running indicator lights up), and the motor starts to work.

3. Unit switching method: short press the Run key to turn off the running indicator light, and short press the Add key to switch units between MPa, Kg/cm and PSI at will. After the setting is completed, turn on the running indicator.

4. Clear function: short press the run key to turn off the running indicator light, long press the Reduce key (▼) for 5 seconds to clear the current pressure value and correct the zero error. After the setting is completed, turn on the running indicator. (When using this function, the pressure switch should not exert pressure. )

5. Turn the pressure adjusting screw at the upper left to make the pointer point to 0.3Mpa of the scale. Lower switching value = upper switching value-switching pressure difference =0.8-0.3=0.5, which is the lower switching value. Turn on the power supply and increase the pressure of the controlled medium (water and gas).
