Take a good line, you must check the gauge wiring methods are correct. Specific detection method as follows: manually open the pump, observe the pressure gauge trends are consistent with the actual pressure value is displayed on the controller, if consensus proves correct wiring; if the value of the gauge is on the rise, and the control panel display Pressure display is on the decline, then prove access terminal 3 and the ground terminal of the 5th line reversed, exchange the two cable. After the wiring is correct, enter the pressure calibration procedure. Specific operational procedures: first manually open Renyiyitai pump, then the gauge readings actually enter into the press to confirm, pay attention to the same value can not be calibrated twice. It represents misuse operation twice, for example: pressure gauge reading after 0.23Mpa enter 0.23 to confirm press ENT. The next time you can not enter calibration is 0.23, you must enter another value recalibration. It is worth noting that, when the pressure gauge at zero pressure state calibration, do not zero, calibrated to a 0.01, or manually play up the pressure after the correction. 6, when the frequency of the frequency calibration frequency inverter and control panel display when the displayed values ??do not match, just need to drive input to the controller in real-time readings press to confirm, pay attention to the same value can not be calibrated twice. It represents misuse operation twice, for example: the drive after reading press ENT to confirm after 42Hz input 42Hz. Next time will not be entered in the calibration 42Hz, you must enter another frequency recalibration.
