LIBERO LINE WOK INDUCTION
ALARMS
Alarms on Libero Line appliances are codified using four characters as follow:
HUI Hob User Interface / HC Hob Control. Also referred as "Power Board" (POW).
E 4 0 0
The alarm code appears:
• For User Interface (U.I.) errors: Some codes appear on left display only, some other are
replicated on both display. No matter if the appliance is single or double zone.
• For power board (POW) errors: The error appears on the U.I. zone associated to the gener-
ator in error or unable to work as a consequence of the malfunction. So, meaning:
➢ In one display only when the alarm impact only one generator inside a specific POW (e.g.
E411: Coil temperature sensor open/not connected). Visualization is done on the U.I. zone
associated to the defective generator. This is done to allow technician to correctly identify
the failed component.
•
Be aware that in some cases more than one generators are controlled by one Zone in the
U.I. (e.g. for the Single zone Fry Top). In this case the error of both generators is showed
in the same U.I. zone. There is not a specific way to indicate which generator is actually in
error.
➢ Replicated on both display if the problem impact on more than one generators and these
generators are controlled by different zones on the U.I. (e.g. E321: Power supply undervolt-
age).
➢ Replicated on both display if there is more than one error associated to different zones in
the U.I.. Theoretically speaking, different specific codes should be showed on every U.I.
zones. By design choice instead just one code (the latest discovered in chronological order)
is replicated on all U.I. zones in error.
Component position of the failure.
For power board related failures indicates the HC. Possible values are: 1 = HC1; 2 = HC2
For user interface related failures indicates the HUI. Only value 1 possible on Libero Line.
Failure detail.
Range 0 ... 9, A, b, C, d, E, F
Involved component.
0 = HUI: Configuration error, UI memory failure
1 = WiFi failure (Not in use on Libero Line)
2 = Special modules ZIC, SAW (Not in use on Libero Line)
3 = HC: Power supply voltage
4 = HC: Coil temperature sensor
5 = (Free)
6 = HC: HC failure
7 = HC: Cooling fans failure
8 = HUI: MACS communication error
9 = HUI: Touch keys failure
