Performing maintenance
Performing maintenance
Carry out the specified configuration, maintenance and inspection work every
six months or, at the latest, when an error message or malfunction makes it
necessary.
All operating media are to be protected in case the product is accidentally
started up.
Disconnect the FCU from the power supply when performing any
maintenance, inspection or repair work.
Once maintenance work is complete, check that the FCU is still working
properly.
Any screwed fittings which have been undone/removed are to be checked to
see that they have been properly resecured.
FCUcleaning
Clean the control panel with a clean, moist cloth. Do not use any chemical
cleaning agents, as these may damage the film attached to the surface of the
FCU. Clean the outside of the FCU with a moist cloth.
Changing the FCU filter element
The FCU has an internal filter element with a differential pressure switch. The
differential pressure switch switches at 2 bar. The message "Filter clogged"
will appear on the display. Ensure that the flow rate control valve is not
closed.
If the filter is contaminated, but the differential pressure of 2 bar cannot be
achieved (e.g. with an inlet pressure <2 bar), then there will be no indication
on the display. Only the message "Flow error" will appear in such cases.
To change the filter, proceed as follows:
1. Put a suitable drip tray in place to catch
the oil (approx. 0.5 l).
Turn the FCU so that the rear side faces
upwards. Ensure that the flow rate control
valve is not damaged.
