7.5.2 Informative tank monitor alarms (green)
F20 Cooling time exceeded for first milking
Alarm is triggered if the temperature set in parameter [h20] is not reached within
the time set in parameter [h21].
The time starts when cooling of the first milking starts.
F22 Forgotten to switch on the
cooling
At the milking time [h41-h43] entered, the cooling was not switched on.
F23 Milk temperature too high for too long
Same as for faults F1 - F3. Setting in parameter [h23 / h24]
F25 Excess temperature directly
When cooling starts, this alarm remains inactive until the milk temperature falls be-
low the temperature set in [h20] for the first time. It is at this point that milk temper-
ature monitoring starts. If the milk temperature subsequently exceeds the temper-
ature set in [h25], the alarm is triggered.
F26 Maximum compressor running time exceeded
Alarm occurs when the total running time of all compressors during a cooling cycle
exceeds the time entered in [h26].
F27 Milk temperature too low for too long
The alarm is triggered if the milk temperature is too low [h27] for too long [h28].
The timer starts when the temperature falls below [h27] and stops again when the
temperature exceeds [h27]. The timer restarts each time the temperature is ex-
ceeded.
F29 Low temperature directly
The alarm is triggered as soon as the milk temperature falls below the tempera-
ture set in [h29].
F30 Power cut directly
The alarm can function only if the optional power pack is installed. Regardless of
the operating mode, the alarm is triggered in the event of a power cut.
F31 Max. time without cooling (starts when cooling manually ends)
Safety function! (This is to prevent that after manual interruption of the cooling
mode is forgotten, to reactivate it or to start the cleaning after the milk removal.)
Timer starts as soon as cooling mode is switched off manually. The alarm is trig-
gered if a new cooling period or washing cycle is not started within time [h31].
F32 Max. time without cooling (starts when washing ends)
Safety function! (designed to ensure that the operator does not forget to start cool-
ing mode after washing.)
Timer starts as soon as washing mode ends. The alarm is triggered if a new cool-
ing period or washing cycle is not started within time [h32].
F33 min. cleaning interval
Alarm is triggered, if a new cleaning does not take place within the time [h33]
F34 Time / date not set
The alarm is triggered if the date and time are lost.
