8. ADDITIONAL FUNCTIONS.
Below, some specific functions of the regulator will be described, enabling the regulator to be used
for various applications.
8.1. Limit switch of the flap.
The regulator is equipped with the possibility of connecting the external limit switch of the tank flap.
The principle of operation of this input consists in immediately switching off the stirrer's operation
at the moment of shorting or opening of this input (depending on the
UU
parameter setting),
made by the connected limit switch of the flap. The return of the stirrer operation (after being
interrupted by the limit switch) follows after the disappearance of the flap opening signal with
a delay of 5 seconds.
At the same time, depending on the
AF
parameter settings made, it is possible to disable the chiller
(unit) operation. The chiller operation is switched off with a set delay in relation to the opening signal
of the flap, so that the momentary opening does not immediately stop the operation of the chiller.
The chiller restarts operation after the flap opening signal disappears, taking into account the
programmed minimum standstill time of the chiller.
8.2. The function of registering the minimum and maximum temperatures.
The SMT-05 regulator has the function of recording in its internal memory the values of maximum
and minimum temperatures that occur throughout the regulator's operating cycle. This function
makes it possible to check whether the milk is stored under the correct temperature conditions.
When the device is switched on, after the end of the programmed delay (parameter
AA
–
see section
9.
), the temperature values are recorded to the regulator's memory. The programmable delay time
of enabling this function allows pre-cooling of the milk after the start of cooling and thus not taking
into account the maximum temperature when the device is started. This time should be selected by
the user for the type of tank and the actual operating conditions of the device.
At any time, the user can read the maximum
and minimum temperaturę
values presently available.
