Operating Modes; Cooling Mode - Liscarroll Engineering LE-200 Installation And Operating Instructions Manual

Operating modes

Operating of Working Levels
OFF mode
(with continuous stirring function)
If the display shows "OFF" the control is in standby-mode.
Permanent stirring function:
In the OFF mode the agitator can be switched on with the button "agitator" and
switched off with the button "OFF". During the stirring cycle, a rotating bar
appears on the display.
If the agitator is not switched off manually or switched to another mode, an
automatic switching off takes place according to the time set in [C25]. (If the
parameter is set to '0' there is no automatic switch off).
The cooling and the cleaning mode can only be selected from OFF mode and it is
not possible to switch directly between them.
CAUTION: The control unit is live even when switched off.

COOLING mode

Press "COOLING" button on foil keyboard in OFF-mode:
- Either LED 'T1' or 'T2' flashes (for target temperature 1 or 2).
- T1 is the normal target temperature (4°C)
- T2 is the deep cool function (2°C)
- At the same time the display briefly shows the current target temperature
before the current medium temperature appears.
- If the other target temperature is desired: Press the "COOLING" button again
(The switching from T1 to T2 can be blocked via parameter [P80]).
- If 'Cooling start delay' [P62] for the 1st milking is programmed cooling will not
start immediately. During the delay the cooling mode LED blinks. Press the
'COOLING' button twice in succession to start cooling without a delay.
- The milk will now be cooled to the set target temperature. The agitator motor
runs continuously. If the milk temperature is already lower than the target
temperature only the agitator operates.
- When the target temperature is reached the compressor switches off.
- The agitator switches off at the end of the 'after-stirring' time [C20].
- During cooling pauses, the agitator switches on periodically: in accordance with
the 'pause time' set [C21], for the duration of the 'after-stirring' time [C20],
in order to ensure an even temperature throughout the milk.
- If the milk temperature exceeds the selected target temperature by the set
'differentials' value [C10 or C11] the compressor and agitator automatically
start again.
