Until May 2019 Valve plug connection
The level sensor is mounted at the lowest possible position in the tank valve
system of the buffer tank. The figure shows the correct wiring between the
level sensor and the CRS+ (3x 0,75mm2).
Note: When the red and green led lights are on, the buffer tank is empty.
From May 2019 M12 connector
A 3 or 4 - wire cable is delivered with the system (colors brown, blue, black, [white])
CONNECTION LEVEL SENSOR TO CRS+ OR CRS M3
The sensor can be connected to an input of the CRS+ or CRS M3. Configure the setting: “ BV is EMPTY
(BV1) ” at ‘ configuration inputs ’. At ‘ test inputs ’ the state of the level sensor can be checked.
Check the functioning of the system at the first milk collection! Check the wiring if the “ empty tank ”
procedure does not work well.
