3.3 Description
General
In the measuring stick, four heated electrodes (sensors) are mounted which project into the medium in accordance with
required switch-point (see also chapter 6). A fifth electrode serves as reference electrode.
Depending on water contact, the filling level is shown by four green LEDs L1 to L4. As grease layer thickness progres-
ses, the LEDs go out top down. When reaching 50 % of max. grease layer, 2 green LEDs are still flashing and when
reaching > 80 %, only 1 red LED is still lighting. Emptying of the separator must be arranged.
Two relays with change-over contact activate the aggregates (signals).
The NC connection can be loaded with 230V/5A AC and is dejammed with a varistor. The NO connection is loadable up
to 230V/2A.
In the housing is a 230V AC mains adapter and a control unit with LEDs to display filling level as well as two buttons for
manual switching-on of relays.
Delays in switching behaviour may result from sensor surfaces coated by grease, dissolving only in the course of several
minutes and admitting a proper test reading. In the case of indication error of the sensor, the cleanliness of the sensor
heads must be checked.
Operators whose plants do not possess of an automatic cleaning system are to check the cleanliness of the sensors
during each disposal and are to clean the sensor heads, if applicable.
