3.2. Controller functions in the cooling mode.
The cooling segment of the MCH-07 controller is equipped with the functions described below.
1. Controlling the operation of the chiller (unit) according to two preset temperatures,
e.g. pre-cooling temperature after milking and the temperature of the target cooling
temperature in the storage process.
2. Delaying the activation of the cooling process for the time needed to finish the milking
process.
3. The supervisory function of the chiller (unit) operation, consisting in the possibility of setting
the maximum and minimum working operation of the chiller (unit), as well as the minimum
time of standstill of the chiller (unit).
4. Option of setting the automatic operation of the stirrer in two variants:
− cyclic operation of the stirrer, independent of the operating condition of the chiller
(unit);
− the stirrer operates continuously during the operation of the chiller (unit), and when
the chiller (unit) is switched off, the stirrer switches to cyclical operation.
5. Manual switching on of the stirrer's work.
6. Saving maximum and minimum temperature values throughout the controller's work cycle;
this function is combined with the possibility of temporally delaying the recording
of temperature data to the controller's memory from the moment of its switching on.
7. Saving the maximum temperature value in the washing process.
8. Monitoring and signaling of the measuring sensor damage.
3.3. Programming for the cooling segment.
The controller is factory-programmed for standard operating conditions. In order to change the
factory default, enter the settings mode and make the required corrections. The following figure
illustrates the programming procedure:
