7 Commissioning

WARNING of risk of injury and material damage
The correct pressure switch installation should be inspected prior to initial
commissioning.
The pressure switch should only be commissioned by trained skilled personnel
who have read and understood the operating manual.
The pressure switch should only be operated within specifications (please
compare the technical data in the data sheet in this respect).

7.1 Operation

7.1.1 Switching point setting (by manufacturer, only on request )
The switching points are set by the manufacturer to the values specified in the order and
stipulated on the rating plate with Pfix.

7.1.2 Switching point setting for rising pressure (by customer)

1. Loosen the fixing screw/fixing cover with the aid of a hexagonal socket spanner.
2. Regulate the system pressure to a value clearly below the desired switching pressure.
3. Now increase the system pressure slowly and observe whether the microswitch triggers at the
desired switching pressure. Correct if necessary with the aid of the adjusting element. Repeat
steps 2 to 3 until the microswitch triggers at the desired switching pressure.
4. Then fix the fixing screw/fixing cover and check the switching pressure setting again.
Readjustment may be necessary after fixing.
Step 1

7.1.3 Switching point setting for failing pressure (by customer)

1. Loosen the fixing screw/fixing cover with the aid of a hexagonal socket spanner.
2. Regulate the system pressure to a value clearly above the desired switching pressure, but only
to the max. operating pressure of the respective pressure switch at the most.
3. Now lower the system pressure slowly and observe whether the microswitch triggers at the
desired switching pressure. Correct if necessary with the aid of the adjusting element. Repeat
steps 2 to 3 until the microswitch triggers at the desired switching pressure.
4. Then fix the fixing screw/fixing cover and check the switching pressure setting again.
Readjustment may be necessary after fixing.
