12 Maintenance
12.1 Safety
Maintenance work may only be carried out by qualified personnel.
WARNING
Risk of injury due to incorrect maintenance or troubleshooting
4
Check the proper functioning of the product, especially the safety features, after every
maintenance or troubleshooting operation.
NOTE
Incorrect maintenance work
Damage to the ejector!
4
Always switch off supply voltage before carrying out any maintenance work.
4
Secure before switching back on.
4
The ejector must only be operated with a silencer and press-in screens.
4
Create atmospheric pressure in the ejector's compressed air circuit before working on the system!
12.2 Cleaning the Ejector
1. For cleaning, do not use aggressive cleaning agents such as industrial alcohol, white spirit or thin-
ners. Only use cleaning agents with pH 7–12.
2. Remove dirt on the exterior of the device with a soft cloth and soap suds at a maximum tempera-
ture of 60° C. Make sure that the silencer is not soaked in soapy water.
3. Ensure that no moisture can reach the electrical connection or other electrical components.
12.3 Replacing the Silencer
Heavy infiltration of dust, oil, etc. may contaminate the silencer and reduce the suction capacity. Cleaning
the silencer is not recommended due to the capillary effect of the porous material.
If the suction capacity decreases, replace the silencer.
ü
Deactivate the ejector and depressurize the pneumatic systems.
4
Detach and replace the silencer.
12.4 Replacing the Press-In Screens
The vacuum and compressed air connections of the ejectors contain press-in screens. Dust, chippings and
other solid materials may be deposited in the screens over time.
4
If you notice that the performance of the ejectors has declined, replace the screens.
12.5 Replacement of the Device with a Parameterization Server
The IO-Link protocol provides an automated process for transferring data when a device is replaced. For
this Data storage mechanism, the IO-Link master mirrors all setting parameters for the device in a sepa-
rate non-volatile memory. When a device is swapped for a new one of the same type, the setting parame-
ters for the old device are automatically saved in the new device by the master.
