1. DESCRIPTION.

The MCH-07 v. 2 controller is a universal, combined controller intended for use in milking

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 v. 2 controller has a waterproof casing (protection class IP65), adapted

for built-up. On request there is also a version with a flange for panel mounting (variant

MCH-07.f). Power as well as control inputs and outputs are led through glands placed on

the lower part of the casing, however, on request, a version with 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 (variant MCH-07.b).

In the set with the controller there is a temperature sensor. In version MCH-07T v. 2

an additional temperature sensor is connected, which controls the heating of the water

temperature during the washing process.

The temperature sensors are located in the rubber cover (protection class IP68), ending

with stainless steel sleeve. The controller signals the failure of the temperature sensor.

In order to install the controller, unscrew the six screws and swivel the front of the controller, paying attention to the cable connecting the upper PCB board with the bottom board.
Page 3 ATTENTION Fixing the casing can be done only by screwing using the marked holes. It is forbidden to drill the housing and fix the casing through such holes, because it causes loss of tightness of the casing. MCH-07T version In the event that the relay no. 4 in the washing segment is set as the stirrer control, then the control of the stirrer of the cooling segment and the washing segment can be combined.

Delaying the activation of the cooling process. This function makes it possible to switch on the controller by pressing the button and the cooling process will be delayed.
Page 10 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: ...

Page 12 3.5. Table of settings for the cooling segment available for the direct user. ATTENTION The controller is equipped with a function that makes it impossible to change the control temperature set by the installer. This function is activated by setting parameter LF=1 (default LF=0).
Page 13 3.6. Description of the cooling segment operation. When the controller is connected to the main, the display shows the currently measured temperature. In addition to displaying the temperature value, the controller does not control any external elements. Pressing the button causes the cooling control operation to start.
Page 14 Disconnecting the controller from the power supply erases the data contained in its memory. 4. WASHING SEGMENT. The washing segment in the MCH-07 v. 2 controller is activated only when cooling is switched off; this activation is indicated by the appearance of the - - - - symbol on the display.

Page 16 4.2.1. Washing programs. Controller’s memory has capacity for 8 programs, with two programs for washing the milking devices and two programs for washing the cooling devices pre-programmed. The remaining 4 spots allow an installer to create programs adapted to the individual needs of an user.
Page 17 4.2.8. Pausing the program. The controller allows to pause (hold) the program execution during its duration. This function allows you to interrupt the program at any time and resume it, which happens exactly in the same place, in which the program was paused. 4.2.9.

Page 20 4.3.2.3. Editing the programs. The controller is equipped with: 4 washing programs (pre-programmed), which can be freely edited by the installer as required, as well as 4 washing programs to be programmed by the installer (they are empty as default). Each program can contain up to 50 steps.
Page 21 ATTENTION 1. When programming the activation of the hydrostatic input (relay no. 8), it is necessary to program the maximum allowable time of pouring water. The time parameter is superior to the hydrostatic signal, providing protection against too much water. Not programming this parameter will result in the lack of reaction to the hydrostatic signal and at the same time the lack of pouring water.
Page 22 ATTENTION 1. Using the procedure described above will remove any settings from the controller's memory while restoring factory settings. Therefore, be consciously using this option. 2. The return to factory settings takes place only after disconnecting and restarting the controller's power supply; changing the Pd0d parameter by itself will not return to the factory settings.
