Question:

How does the CHINT CJX21210 control the starting of the air pump?

When the air pump is less than 0.6M, the compressor stops and stops at more than 0.8M, the compressor is 220V, the pressure gauge is contact type XY100, and then the two contactor is CHINT CJX21210. The trouble is detailed wiring, thank you!Is greater than 0.8M contact is usually open without gas, the pressure is equal to 0.6 to 0.8M pressure, is the need to open the compressor gas,This signal is supplied by a pressure gauge with a contact type XY100 switch. I want to ask you, master contactor after live, it is necessary to self-locking to gas to 0.8M, but after the 0.8M, you need another contactor, the front of the self-locking contactor disconnect And how do A1 and A2 connect to the L line or the N line? Specific how wiring, SORRY, 13 years ago I also have intermediate electrician certificate, now forget completely, I have no face to face you, please help me,

Specific wiring diagram, it is better to have a diagram indicating SORRY

Xy100 is equivalent to the start stop button, and the 1 contactor is OK

The control circuit has nothing to do with the pressure gauge. The pressure gauge acts as a monitoring function and controls the pressure automatically by the pressure switch.
