Fire hydrant pump spray pump pump pressure gauge and spray pump pressure switch is how the wiring?
The pressure gauge does not seem to be wired.
Pressure switch that is a white switch, the 24V is introduced into the pressure switch side, and then from the other end leads to the 24V relay 13 feet, the 24V negative to 24v relay 14 feet (13,14 can tune), and then the relay A pair of constant contact can be connected to the pump line.
Pressure to open a total of four lines: a pair of direct access to the alarm module feedback, a pair of lines directly to the pump control cabinet open pump
Electric contact pressure gauge a total of three terminals: a connection limit, a lower limit, a public, three lines directly to the regulator control box can be the corresponding terminal, the door has a corresponding wiring diagram
