Fire hydrant pump, spray pump, starting pump, pressure gauge and spray pump, pressure switch is how to wiring?
A total of 4 lines of pressure: a pair of lines directly to the alarm module feedback, a pair of lines directly to the pump control cabinet pump startThe electric contact pressure meter has 3 terminals: one upper limit, one lower limit, one public and three wires directly to the corresponding terminals of the voltage regulator box, and the corresponding wiring diagram is on the box door

The pressure gauge doesn't seem to be connected.It is a pressure switch switch, the 24V is introduced into the pressure switch, and then come out from the other end, connected to the 24V relay 13 feet, the negative 24V connected to the 24V relay 14 feet (13, 14, and then put on) a pair of normal relay contact is connected with the pump start line can be strong.
