9.15.2 Compressor switch-on delay / pre-agitating
(Only useful when using a robot)
If the milk cooling tank is filled by a robot, filling from below takes place via the tank
outlet. For some tank types, the temperature sensor is positioned very close to the
tank outlet. For this reason, an increase in the milk temperature is measured during
filling, although the actual milk temperature has not yet risen (due to a heat bubble
at the outlet by the type of filling). This leads unnecessarily to the frequent switching
on of the compressor and thus to an increased wear of the cooling system.
The parameter [P6] can be used to parameterize a 'pre-agitating time' in which the
agitator starts before the compressor is switched on. This is intended to ensure that
the warm milk at the outlet is mixed with the remaining cold milk in the tank and the
compressor is switched on only after the pre-agitating time has elapsed if the total
milk quantity is above the target temperature.
9.15.3 Compressor lock via digital input (by robot)
With this function it can be set that a robot influences the cooling performance. If the
robot sends a signal to the correspondingly configured digital input, the compressor
is switched off as long as the signal is present.
Note: With settings 3 and 4 in parameter [P70], the compressor lock can be deac-
tivated via button “Cooling” until the next cooling start.
Cancel compressor lock:
Press the OFF button,
Start cooling mode immediately (without cooling start delay) by double-clicking the
“COOLING” button.
The compressor lock is deactivated once (until the next cooling start).
