7.5 Listing fault codes and their description
7.5.1 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 and H15]
F6
Power cut alarm
Alarm functions only if optional power pack is installed.
Alarm is triggered if power cut lasts longer than the time entered in param-
eter [H20].
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]
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 functions only if optional “Welba agitator monitor” is installed and
parameters set [A71].
Alarm is triggered if, after the previous stirring, more than the number of
minutes set in [H41] have passed without the agitator restarting.
