6.5 Listing fault memory and description
6.5.1 Critical tank monitor alarms (red)
F1
Milk temperature too high for too long 1
If during cooling mode the milk temperature exceeds the temperature limit
value entered in [H10] for longer than the time entered in [H11], fault re-
port F1 appears.
H11 here is the limit value for the sum of all time overshoots (t1, t2, t3
etc.)
F2
Milk temperature too high for too long 2
as F1, but relating to [H12 and H13]
F3
Milk temperature too high for too long 3
as F1, but relating to [H14 und H15]
F6
Power failure alarm
Alarm is only possible, if all power packs are charged!
Alarm is activated if power failure time lasts longer than parameterized in
[H20] and the milk temperature is higher than parameterized in [H19].
F11 Minimum washing temperature not reached
Alarm is triggered if in the main washing stages the minimum water tem-
perature selected in [H30] is not reached.
F12 Minimum acting time not reached
Alarm is triggered if in the main washing stages the minimum water tem-
perature selected in [H30] has not had enough time to act.
Minimum acting time = [H31]
F13 Cleaning time too short
Alarm is activated if the cleaning stops earlier than the time [H32] that has
been set.
F15 Agitator fault in cooling mode (milk not stirred)
Alarm functions only
if optional “Welba agitator monitor” is installed and
parameters set [A71].
Alarm occurs after the cooling mode is started, if a backpressure by the
milk has not been detected on the stirrer within the time [H40].
F16 “No stirring” time exceeded
Alarm ca
n only occur if the „agitator monitor“ is parameterized according
to [A71]!
Alarm is triggered if more minutes have passed than set in [H41] or the
minimum term [H42] was not achieved without a restart of the agitator.
The display blinks to
indicate faults.
