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 OP is available. In that
case, the menu items [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 [SPx] or [FHx].
>
[SPx] / [FHx] decreases if [OP] is reduced to a value ≤ [SPx] / [FHx] after
setting [SPx] / [FHx].
> If [OP] is increased, [SPx] / [FHx] also increases if [OP] and [SPx] /
[FHx] 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 the 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 possib-
le, 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 (→ Table10-1).
