LT39xx Electronic sensor for level and temperature

u Select [OFS]:
u Set the value for the offset.
[OFS]
9.5.4 Set medium
u Select [Medl]:
u Set sensitivity matching the medium to be detected:
[Medl]
[CLW.1] = Water, water-based media, coolant emulsions.
[CLW.2] = Water, water-based media, coolant emulsions for temperatures > 35°C (installation in cli-
matic tube).
[OIL.1] = Oils with an increased dielectric constant (e.g. some synthetic oils).
[OIL.2] = Oils with a low dielectric constant (e.g. mineral oils).
[Auto] = Automatic medium detection.
u In case of doubt, select [OIL.2] for oils.
u Check proper function by performing an application test!
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.
9.5.5 Set overflow prevention
u Comply with minimum distances and installation instructions.
u Select [OP].
u Define the position of the overflow prevention OP.
The option [OP] = [OFF] deactivates the overflow prevention OP.
[OP]
u Set [OP] before [SP1] or [FH1].
w If [OP] is set to a value ≤[SP1] / [FH1] after setting [SP1] / [FH1], [SP1] / [FH1] shifts
downwards.
w If [OP] and [SP1] / [FH1] are close to each other (1 x step increment), [SP1] / [FH1]
increases if [OP] increases.
If the overflow prevention is deactivated [OP] = [OFF] or [MEdl] = [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.
With the setting [OP] = [OFF], the parameter [cOP] is not available.
9.5.6 Adjust overflow prevention
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.
u 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.
