For programming carry out the following steps in the indicated order.
Step Programming
1 Selection of the display unit
Set the required display unit: cm / inch.
Select the display unit before setting values for the para-
meters (SPx, rPx, OP). This avoids rounding errors gener-
ated internally during the conversion of the units and
enables exact setting of the values.
Setting at the factory: Uni = cm.
2 Setting to the medium
Return to the main level of the menu (by repeatedly
pressing the Mode/Enter button).
Set the appropriate sensitivity for the medium and the
appropriate mode of detection.
The following settings can be chosen:
• MEDI = CLW1 for water, coolant emulsions, hydrous
media.
• MEDI = CLW2 for hydrous media with temperatures
> 35°C (mounted in the climatic tube).
• MEDI = OIL1 for special (e.g. synthetic) oils or media
with a dielectric constant that is a little higher than
that of mineral oils.
• MEDI = OIL2 for mineral oils (DK ≈ 2).
Also select the setting MEDI = OIL1 if the medium is
detected with MEDI = OIL2 but on the whole the sensor
sensitivity is too high. In case of doubt ensure the correct
function by performing a test in your application.
Note: If CLW1 or CLW2 is selected build-up (e.g. metal
swarf) is suppressed. If OIL1 or OIL2 is selected, a bottom
layer of higher dielectric water or swarf which is a few cm
high is suppressed. If no oil layer is present (or if it is very
thin), the bottom layer is detected.
3 Setting of the offset value
The zone between tank bottom and lower edge of the
measuring probe can be entered as offset value (OFS).
Thus display and switch points refer to the real level.
Setting at the factory: OFS = 0.
The setting values OFS are indicated in the table on page 36.
Please note: Select OFS, before setting values for the
parameters SPx, rPx and OP. This avoids inadvertent
maladjustment.
