3.4.6. Manual work of the stirrer.
In addition to the automatic work of the stirrer, the controller allows you to manually
switch on the stirrer at any time (when the stirrer is not working). Depending on the
settings made in the CP parameter, you can set two variants of manual work:
CP=0 – continuous stirrer operation from the moment of manual activation until
the manual switch-off,
CP>0 – work for a specified period of time; the value of the CP parameter (>0) means
the working time of the stirrer activated manually; the stirrer operation in this
variant can also be interrupted at any time by pressing the button
.
3.4.7. Saving the maximum and minimum temperature values during the cooling
process.
The controller has a function of saving in its internal memory maximum and minimum
temperature values that occur throughout the controller's entire cycle. This function
makes it possible to check whether the contents of the tank are stored
in correct temperature conditions.
At the moment the cooling is switched on, after the programmed delay has elapsed
(parameter AA – see section 3.4.1. Table of settings for the cooling segment),
the minimum and maximum temperature values are saved in the controller memory.
The programmable delay time of enabling this function allows the fresh milk to be pre-
cooled and thus does not take into account the maximum temperature when the cooling
is started. The factory setting is 2 hours, however, this time should be selected according
to the actual operating conditions of the controller.
At any time, you can read the currently available maximum and minimum values. This is
done by briefly pressing the S button and selecting the parameter H0 (maximum value)
or parameter L0 (minimum value).
ATTENTION
In the absence of entries of maximum and minimum temperature values in the
controller's memory the symbol --- appears on the display.
Clearing the memory of maximum and minimum temperature values is caused:
automatically after turning the cooling off and on again; switching off the cooling
itself does not erase the memory, it takes place only after switching it on again,
in the event of a power failure.
3.4.8. Saving the maximum temperature value during the washing process.
The maximum temperature that is present when the controller is not in cooling mode is
also written to the controller's internal memory. Because the washing process must be
carried out with the cooling off, the temperature then present is also the maximum
temperature in the washing process. However, if the washing process is not carried out
