6 Commissioning
1. Before commissioning, ensure that all connections of the PE 6 are correctly
carried out.
2. Apply the compressed air to the system.
3. Check that the switch outputs are functioning properly.
7 Operation
Vacuum switch pressures too high
The vacuum switch has only been designed for operation with vacuums (referring
to atmosphere). Pressures up to 5 bar do not cause damage to the switch;
however, pressures from 2 bar may adversely affect precision and service life.
O Observe the maximum permissible pressure values on the rating plate and in
the technical data.
When switching inductive loads, use a recovery diode on the load!
Setting switching points (pressure and vacuum switch)
Depending on the PE 6 variant used,
W
one switching point with fixed hysteresis or
W
two switching points can be set.
Switching points are set via the teach button (2) (see
Outputs 1 and 2 operate independently of each other.
One switching point with fixed hysteresis
1. Press button (2) for approx. 2 s until both LEDs flash alternately.
2. Press button (2) until the LED of the desired output lights up.
3. Apply the vacuum/pressure for the desired teach point.
4. Press button (2) for approx. 2 s to set the teach point. The LED will flash.
– Vacuum switch:
Switch-on point (SP) = teach point (TP) - 20% of TP
(Example: TP = -700 bar, SP = -560 mbar)
Fixed hysteresis (2% F.S. = 20 mbar)
– Pressure switch:
Switch-on point (SP) = teach point (TP) -5% of TP
(Example: TP = 6 bar, SP = 5.7 bar)
Fixed hysteresis (2% F.S. = 200 mbar)
5. Repeat the process from step 1 for the second output.
Two switching points 6
1. Press button (2) for approx. 2 s until both LEDs flash alternately.
2. Press button (2) until the LED of the desired output lights up.
3. Apply the vacuum/pressure for the desired switch-on/switch-off point.
4. Press button (2) for approx. 2 s to set the first switching point (the sequence of
switching points is freely selectable).
The LED will flash.
5. Apply the vacuum/pressure for the desired switch-off/switch-on point.
6. Press button (2) for approx. 2 s to set the second switching point.
7. Repeat the process from step 1 for the second output.
Resetting to factory settings
1. Disconnect the PE 6 from the operating voltage.
2. Hold down the (2) button and apply the operating voltage.
Both LEDs will flash.
3. Press button (2) for approx. 2 s until both LEDs go out.

8 Maintenance
The PE 6 is maintenance-free. Please contact the service department at AVENTICS if
you have any technical problems.
9 Cleaning and servicing
Solvents and aggressive cleaning agents
Solvents and aggressive cleaning agents could damage the PE 6.
O Only use water for cleaning and, if necessary, kerosene or benzine.
How to clean the PE 6:
1. Make sure that all relevant system parts are not under voltage or pressure.
2. Clean the PE 6.
10 Disposal
O Dispose of the PE 6 in accordance with the applicable national regulations.
