4.3 Automatic detection of the operating mode
A proper operation of the tank monitor is only possible if it can detect reliably the
operation modes of the milk cooling tank that has to be monitored! These are
- cooling
- cleaning
- empty (Off)
This detection is carried out - without additional operation - only by signals of the
milk cooling tank or tank controls. The wiring of the tank monitor depends on the
basic design of the milk cooling system.
If the control of the milk cooling tank provides continuous signals for "Cleaning ac-
tive" or "Cooling active", these are to be used preferentially! This guarantees the
highest detection reliability!
If this is not the case, external signal transmitters and sensors must be connected to
determine the correct operation mode. These so-called "trigger signals" are signal-
izing to the tank monitor when the corresponding mode starts or ends.
The correct connection of the external signal transmitters and sensors is described
in section 4.5.
