Electric valves connection

Connect cables to the individual electric valves. Connect each pair of wires to the electric valves corresponding to the individual sections. For motor valves, it is crucial to maintain the correct wire polarity for each valve. Incorrect polarity will cause the valve to operate in the opposite direction. It is recommended to connect one valve to check its direction and then connect the remaining valves in the same way.

Depending on the model and manufacturer of the electric valves used in the sprayer, we can distinguish at least two types of connection blocks. Figure 5.20 presents two types of connection blocks with a wiring diagram.
