The settings [CLW.1] and [CLW.2] suppress deposits (e.g. metal swarf).
The settings [OIL.1] and [OIL.2] suppress a bottom layer of higher dielectric
water or swarf which is a few cm high. If no oil layer is present (or if it is
very thin), the bottom layer is detected.
With the setting [MEdI] = [Auto], no overflow prevention is available. In that case,
the menu points [OP] and [cOP] are not available.
10.2.4 Set overflow prevention [OP]
►
Comply with minimum distances and installation instructions.
►
Select [OP].
►
Define the position of the overflow prevention OP.
The option [OP] = [OFF]
deactivates
the overflow prevention OP.
OP
►
Set [OP] before [SP1] or [FH1].
>
If [OP] is reduced to a value ≤ [SP1] / [FH1] after setting [SP1] / [FH1],
[SP1] / [FH1] shifts downwards.
> If [OP] is increased, [SP1] / [FH1] also increases if [OP] and
[SP1] / [FH1] are close together (1 x step increment).
If the overflow prevention is deactivated [OP] = [OFF] or [MedI] = [Auto], the
reliable function of the sensor must be verified with particular care. Switch-
on and switch-off processes and special operating states such as very full
tanks, possible maintenance and cleaning operations are to be considered
in the verification.
For setting [OP] = [OFF] the menu item [cOP] is not available.
10.2.5 Adjust overflow prevention [cOP]
Only adjust the overflow prevention OP when the unit is installed.
If possible, carry out the adjustment when the tank is empty.
The tank may be partly filled.
►
Make sure that the overflow prevention OP is not covered by the
medium. Observe the minimum distance between the overflow
prevention OP and the level (→ table 10-1).
