Our unit has a 2.2kW water supply motor, running with EV1000. How to control according to the remote pressure gauge? Is to control the pressure within a certain range. Read the instructions, there is a process closed loop control parameters, but not quite understand.. please expert advice. It's best to say what parameters you need to change.Added 15 points to answer satisfaction.
A specification is very simple, I do I happen to water without Emerson, you can set the PID terminal operation, process control, pressure of fifteen percent to twenty-five, remote pressure gauge 1.6MPa, GND, red, green ten 10V yellow VI, if I can help you find the manual selected parameter settings, welcomed the exchange of my QQ907187542 if you have an electronic version of the instructions can also send me a
This is very good, quack, I am now out of the machine installed, in the evening to give you a satisfactory answer, the best for me to keep
Method for controlling water pump by remote pressure gauge by Emerson frequency converter:The remote contact signal is first transmitted into the PLC, and after the arrangement, the starting signal of the frequency converter is uniformly sent through the PLC. PLC can judge or delay method to control the frequency converter start and stop pump action, to achieve not only switch control water pump, but also soft soft stop pump effect. As for the wiring, relatively simple, PLC contact is connected to the frequency converter to start, stop contact. Of course, the water pump protection circuit is completed. Logical control is done by PLC.Note: it is not suitable to control the frequency converter directly with the contacts of the remote pressure gauge. First of all, the contact jitter, will damage the inverter, and secondly, the number of contacts is not enough.
