You can let the adjustment point be determined by POINTRAC 31.

In this menu item you can activate or deactivate the current output.
The POINTRAC 31 checks if with activated current output there is

really an instrument connected.
If no instrument is connected to the current output, you have to deacti-

vate the current output.

In this menu item you can select the switching behaviour of the sen-

sor.

You can choose between an 8 - 16 mA characteristics or a 16 - 8 mA

characteristics.

In this menu item you can also define the switching behaviour in case

of fault. You can select if the current output should output 22 mA or

< 3.6 mA in case of fault.

In this menu item you can select which mode the sensor should oper-

ate in.
You can choose between overfill and dry run protection.
The relay outputs of the sensor react accordingly.
Overfill protection = the relay will deenergise (safe condition) when

Dry run protection = the relay will deenergise (safe condition) when

the min. level is reached.
Make sure that you have selected the correct characteristics. See
