Maintenance

The FMR is to a large extent maintenance-free when used as intended.
ATTENTION!
If the exterior becomes soiled, FMR should be cleaned only with compatible cleaning agents.
In case of doubt, make a test of compatibility.

Check whether the allocation of the end
positions to POS-MIN and POS-MAX via
function TUNE-POS is correct.
If incorrect: repeat execution of TUNE-
POS.
If correct: TUNE-POS with this allocation of
end positions is impossible, they lie too
close together.
To determine POS-MIN and POS-MAX,
drive the actuator in each case in the
direction shown on the display.
Remedy
Connect pressure supply
Check process, if applicable, switch on
pump or open shut-off valve
• Check supply pressure
• Execute AUTOTUNE
