9.8 Function second temperature sensor
The second temperature sensor (F 2) may have two different tasks or functions.
U
To act as a monitoring sensor (redundancy) for the first sensor. An adjustable
difference between the two measured values gives rise to an alarm.
To regulate the heating temperature / holding temperature during washing.
The second sensor input must be activated by an appropriate parameter setting [A50].
The maximum temperature difference for the monitoring sensor in comparison to the
regulating sensor (F 1) is set in [h38]. If the set temperature difference is exceeded
U
for longer than 5 minutes, fault code [F38] is displayed.
If F 2 develops a fault (break or short-circuit), fault code [F38] will also be displayed
U
after 5 minutes.
.9 Level alarm during cooling
9
(Fault code F52)
Safety function:
The level input will be monitored during cooling.
In the case of systems with robot operation, depending on the layout of the system,
the washing line may be connected permanently. If, for example, a water valve
jams and the water level rises, water could be forced into the tank via the washing
line. In this case, once the electrode is reached, an alarm is given and the outlet
valve is opened.
All relevant settings are found in [P40].

Automatic / convenience functions
8.10.1 Automatic start continuous agitating mode
to
after exiting cooling mode
Setting in parameter [P23].
When the cooling operation is stopped by the milk truck driver, a continuous agitating
mode can be initiated automatically in order to achieve better mixing of the milk in the
tank.
8.10.2 Automatic start cooling mode after successful cleaning
to
Setting in parameter [P60].
When using a robot, it is possible to start the cooling mode automatically after a
successful cleaning.
If cleaning is not successful, the control remains in cleaning mode and manual
acknowledgement is necessary.
