1. DESCRIPTION.
The third generation of MCH-07 controller is a universal, combined controller intended for use
in milking machines (devices) and milk tanks. This controller allows you to cool the milk contained
in the tank and to carry out the milk tanks and milking devices washing process.
The controller is characterized by flexibility in adapting it to various requirements. It is fully
programmable at the installation stage, and at the same time protected against possible
interference by the user in the settings.
The controller consists of two complex segments:
cooling segment,
washing segment,
however, it is not possible, even accidentally, to activate the washing process during the cooling
process. The washing segment is activated only when the cooling is switched off.
The MCH-07 controller has a waterproof casing (protection class IP65), adapted for built-up.
On request also the following variants are available:
MCH-07.f with a flange (for panel mounting), in which power as well as control inputs and
outputs are led through glands placed on the back of the casing,
MCH-07.b with the glands placed on the back of the casing is provided, which allows the
controller to be installed in such a way that the wires are hidden.
In the set with the controller there is a temperature sensor. In version MCH-07T an additional
temperature sensor is connected, which controls the heating of the water temperature during
the washing process.
The temperature sensors are in the rubber cover (protection class IP68), ending with stainless steel
sleeve. The controller signals the failure of the temperature sensor.

5. DESCRIPTION OF THE CONTROLLER FUNCTIONS. Below, some specific controller functions will be discussed, enabling the controller to be used for various applications. 5.1. Registering the minimum and maximum temperatures. The MCH-07 controller has the function of recording in the internal memory the values of maximum and minimum temperatures that occur throughout the controller's entire cycle. - Page 15 5.2. Alarming the exceeding of the correct temperature range. The controller has the function of signaling the exceeding of the set temperature range.

Each program can contain up to 100 steps (sequences), lasting from 1 sec.
- Page 27 Recommendation Before you start creating a new program or making a significant modification to an existing program, it is recommended to create a table with a new/modified program beforehand. For convenience the table should look similar to the tables of the factory programs. It should be remembered that after 30 sec.
