TEMP SENS
SLOPE_Z1 (Rear
zone on Tesla
POW)

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 § 4.4.7.3.4.

PIN FMEA ERROR

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.

DATA_CRC_ER-
ROR

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
