7 Operation
Setting the switching point
Switching points are set via the teach button (2) (see ).
1. Apply the vacuum/pressure for the desired teach point.
2. Press button (2) for approx. 2 s to set the teach point. Both LEDs 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) -20% of TP
(Example: TP = 6 bar, SP = 5.7 bar)
Fixed hysteresis (2% F.S. = 200 mbar)
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.
Factory setting
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
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.
CAUTION
Too high pressure
A too high pressure can damage the PE 6:
W
The PE 6 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.
W
The PE 6 pressure switch is designed for a maximum overpressure of 15 bar.
O
Note the maximum permissible pressure values. This information can also be
found on the rating plate and in the technical data.
When switching inductive loads, use a recovery diode on the load!
Variants Switching point
Vacuum switch -600 mbar
Pressure switch 6 bar
CAUTION
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.
