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.
