Alarm description
Implemented on Tesla POW only: Slope detection alarm
(temperature not increasing, stuck,) on front or rear coil. This
diagnostic is only active when zone temperature is below
55°C. Intervention time depends on requested power:
• Level 8, 9, 10 : 2 min 30 sec
• Level 7
: 4 min 30 sec
• Level 5, 6
: 7 min
• Level 4
: 9 min 30 sec
• Level 3
: 14 min
• Level 1,2
: More than 3h
The error is self-resetting after two minutes that the U.I. is
OFF or COOLING_DOWN state.
NOTE: For Tesla POW with single zone configurations this
diagnostic help to diagnose the reversal of the sensor with the
dummy resistor (100kOhm resistance).
Tesla HC, HOB & WOK: Wrong electrical connection: A
cooking plate temperature sensor is present on BT300 or
BT400 connector. In this case the error is not self-resetting.
Tesla POW, FRYTOP: Two possibilities:
Cooking plate temperature sensor open, not connected, bad
circuit or short circuit. Bad circuit means temperature ≥ 290°C
on Tesla POW.
HOB or WOK configuration loaded in a FRYTOP appliance.
The error is self-resetting in case of sensor open or not con-
nected, not self-resetting in case of bad circuit or short circuit.
NOTE: Diagnostic is executed on both generators (Front and
Rear) within the single Tesla POW §
TEST WITH GENERATORS
The alarm is showed on both display (left and right). On Libero
Line this may happen when a wrong firmware is used for the
hardware.
15 Volt supply out of window
Tesla POW: IGBT/heat-sink sensor open or short or >130°C
(115°C for deactivation). One single error for both IGBT tem-
perature sensors within an POW.
Foucault HC: IGBT/heat-sink sensor open or short. The error
is self-resetting
APD relay glued, can't switch off power induction circuits.
Solder/assembly fault inside power board: short circuit on ad-
jacent pin of safety ADC.
NOTE: On Tesla POW, this error appears (on both genera-
tors) if a coil temperature sensor is disconnected / recon-
nected when the POW board is already powered on.
Foucault POW only: Internal power table missing.
Foucault POW software is equipped with an internal power
table to be used when the POW is connected without an UI
and power level set is established by a potentiometer (modu-
lar cooking range).
Even if not used on Libero Line, the POW software check the
presence of the internal power table at power-on
Power supply frequency detection error.
Acceptable range: 40% to 60% of the duty cycle @50Hz.
