im buying [smc VQZ 212 5YZ1 C6] 3 port solenoid valve with 2 possible position(let say A and B).
This solenoid work with 24VDC and have 3 pin/ wire. There is No 1, No 2 and GND pin.
I will never tried to wiring directly without enough information. How to switch the solenoid valve position (from A to B and from B to A) with 2 wire 24V adapter (24V and GND)? What does (-)(+) mean in wiring diagram? The full manual book is here
