Pressure switch PC-2 with pressure gauge for pump and home water system

Product detailed description

The PC-2 pressure switch with integrated pressure gauge can be used with submersible and surface pumps (230V). It can also be used for direct connection to a pressure tank. Pressure switches control pump operation depending on the set switch-on and switch-off pressure. The PC-2 pressure switch has a 1” inlet and outlet. Electrical connection   Connect the power cable connections to the lower rail and connect the pump cable to the upper rail. Connect the grounding (yellow-green) power cable and the pump cable to the two screws located outside the rails. Technical data   Working range:  1.6 - 4.6 bar Factory setting:  1.4 - 2.8 bar Max. current consumption:  16A Pump power supply:  230V, 1 phase Pressure regulation Always disconnect the power supply before removing the switch housing. If the user needs to change the factory settings, this can be done using two adjustment screws. Screw no. 1 sets both the switch-on and switch-off pressures. Tightening increases the pressure and at the same time increases the closing pressure. Adjustment screw no. 2 regulates only the switch-off pressure. Tightening it increases the drop. The setting change should be made first by adjusting the pressure with screw no. 1 to the expected value, and finally by adjusting screw no. 2 for switch-off to the expected value.
