The zero-point adjustment is also reset. The zero point may have to be
reconfigured [CAL].
Severe personal injury or property damage due to moving machine/
system parts
Resetting the device to its factory settings changes the switching points and the
configuration of the signal output. The changed signal at the signal output can set
the machine/system in motion.
O Make sure that the machine/system is not put into motion and no persons are
in the transporting area during "reset to factory settings".

with the lowest value.
You can use the buttons or
counter value. The decimal points indicate which block of three numbers from the

Service and Repairs

External contamination
Damage and disruptions due to penetrating fluids or contact with aggressive
media
Penetrating fluids and use of solvents and aggressive cleaning agents can lead to
damage and disruptions.
In this case, reliable ejector function can no longer be guaranteed.
O Only clean the ejector with a damp, lint-free cloth.
O Only use water and, if necessary, a mild detergent for cleaning.
O Make sure that the silencer and the controller are not soaked in fluid.
O Do not use a high-pressure cleaner.
Silencer
Damage due to excessive force
Exerting excessive force when tightening the mounting screws can lead to
damage to the housing.
O Observe the maximum torque of 0.5 Nm when tightening the mounting screws
on the silencer module.
We recommend that you also replace the damping plate when exchanging
the silencer insert.
The open silencer can become soiled if exposed to very heavy contamination by dust,
oil, etc. and thus reduce the suction capacity. It should be replaced in this case. Due
to the capillary effect of the porous material, cleaning is not recommended.
Press-fit screens
Damage to ejector system due to missing press-fit screen
Fluids and foreign objects could penetrate and destroy the ejector.
O Do not operate the ejector system without press-fit screens.
Press-fit screens are installed in the vacuum and compressed air connections.
Over time, dust, chips and other solid matter can deposit in these screens.
If the ejector system performance noticeably drops, the screens can easily be
replaced.
