PRESSURE SWITCH 8 BAR 230V

Pressure switches designed for automatic switching on and off of electric motors for hydrophore and submersible pumps.

Technical data:
Supply voltage 230V
Rated frequency 50/60 Hz.
Connection: internal thread R08, ¼”
Max rated current 16A
Pressure regulation range 1-8 bar (*)

(*) Delta, i.e. the difference in supply and discharge pressure, should be between: Δ min = 1,5 bar and Δ max = 5 bar

To adjust the switching on and off of the pressure switch:

1. Remove the switch housing by unscrewing the black plastic cover on the front of the device
2. First, adjust the switching pressure with adjusting screw No. 1. By turning to the right (clockwise) we increase the pressure, to the left we decrease the pressure. By increasing or decreasing the switching pressure with screw No. 1, the shut-off pressure changes at the same time: e.g. if we increase the switching pressure of 2.0 bar to 3.0 bar, the shut-off pressure also increases by 1.0 bar.
3. Secondly, adjust the shut-off pressure with adjusting screw No. 2.
4. NOTE: Adjusting the cut-off pressure does not change the cut-in pressure.

By turning to the right we increase the pressure, to the left we decrease the pressure.
