Filter change
NOTICE
Maintenance of the device is limited to the inspection of filter
saturation and replacement of the filter.
The LED status ring indicates the status of the particulate filters
(pre-filter and main filter). Filter saturation can also be reported
via the M12 interface to a higher-level control.
The saturation of the adsorption filter is not indicated via the
LED status ring.
After a certain period of time, depending on the level of
pollutants/impurities present the activated carbon will become
saturated. The time until saturation occurs needs to be
determined, and the filter should then be regularly replaced
whenever this time limit is reached. If the gases that are
supposed to be separated out are noticeably present in the
outlet air stream, change the adsorption filter immediately.
