Three methods of adjustment for the 3-Phase Single Pump Controller.

The 3-Phase Single Pump Controller can be adjusted in the following way.

Firstly, set the 3-Phase Single Pump Controller pressure limit to 1.5MPa (upper switching value) and issue a contact signal. The procedure is as follows: open the cover and loosen the locking device; then turn the set value adjustment screw clockwise to make the set value change from large to small until the switch contact switches at 1.5MPa; finally, screw the locking device. Secondly, to set the lower pressure limit to 0.5MPa (lower switching value) to send a contact signal, the operation steps: open the cover and loosen the locker; then turn the set value adjusting screw counterclockwise to make the set value change from small to large until the switch contact switches at 0.5MPa. Finally, tighten the locking device.

To set the control pressure

First, short press the operation on/off button of the 3-Phase Single Pump Controllerto turn off the operation indicator, and the pressure control system is switched off. Secondly, to set the upper or lower control limit: press the SET key once briefly to enter the lower limit setting state (corresponding to the lower limit indicator light on) and set the value, after setting the lower limit is complete, press the SET key briefly to enter the upper limit setting, the setting method is the same as above. Thirdly, after the setting is completed, press SET to store the set value into the computer chip automatically. After parameter modification, no key operation within 5 seconds will automatically save the current parameter setting. Fourthly, press the RUN ON/OFF key again (corresponding RUN indicator light on), and the motor will start working.

Unit switching method

Close the Run key on the 3-Phase Single Pump Controller and press the Increase key briefly to switch the unit between MPa, Kg/cm2, and PSI at will. Turn on the run indicator when the setting is complete.

Zeroing function

Close the Run key of the 3-Phase Single Pump Controller and press and hold the Decrease key for 5 seconds to zero the current pressure value and correct the zero error. When the setting is complete, the operation indicator turns on. No pressure should be applied to the pressure switch when using this function.
