≥ 170V ± 5V for more than 1s, it will
automatically resume working, if the
voltage is < 170V ± 5V within 10s, the
buzzer will give out two long and three
short beep prompts every 5 seconds,
and the alarm will be cancelled after
about 90s or according to the tempe-
rature of the Lapitec plate that is lower
than 60 °C.
IGBT Over-temperature
If the IGBT temperature is too high,
the heating will stop immediately, the
power display will display “
E
”, and the
timing display will display “
E0
” and the
buzzer will give out four long and three
short beep prompts every 5 seconds.
After twice sounding, change to the
shutdown stroke, and the warning beep
will disappear.
Overvoltage protection
The equipment has been designed, te-
sted and manufactured to withstand
1200 V impulse surges of 1.2/50 μs du-
ration without malfunction or damage.
Performance against interfe-
rence
The equipment has been designed, te-
sted and manufactured in accordance
with IEC 61000-4-4-2004 against fast
transient interference up to 1500 V du-
ring normal operation, without damage
or the need for restoration.
Over current protection
When the working current exceeds the
set value, the circuit will automatically
adjust, and the constant input current
will be within the safe range. When the
main circuit is of short circuit and over-
current occurs, the fuse will be used for
fuse protection.
Safety mat detection
The cooktop functionalities can be acti-
vated only if the safety mat is in the
correct position on the cooking surface.
When the safety mat is not detected by
the system, the “
C
” error code is shown.
Normal operation is guaranteed as
soon as the safety mat is in its designa-
ted position.

Errors
NTC1
sensor open circuit anomaly
When the induction cooker is in stan-
dby or working state and the IGBT
sensor (NTC1) is of open circuit, the
power display will show “
E
”, the timing
display will show “
E7
”, and the buzzer
will give out four long and five short
beep prompts every 5 seconds.
NTC1
sensor short circuit anomaly
When the induction cooker is in stan-
dby or working state and IGBT sensor
(NTC1) is of short circuit, the power di-
splay will show “
E
”, the timing display
will show “
E8
”, and the buzzer will
give out four long and four short beep
prompts every 5 seconds.
NTC2
sensor open circuit anomaly
When the induction cooker is in stan-
dby or working state and NTC2 is of
open circuit, the power display will
show “
E
”, the timing display will show
“
E9
”, and the buzzer will give out three
long and five short beep prompts every
five seconds.
NTC2
sensor short circuit anomaly
When the induction cooker is in stan-
dby or working state and NTC2 is of
short circuit, the power display will
show “
E
”, the timing display will show
“
EE
”, and the buzzer will give out three
long and four short beep prompts every
five seconds.
Pot detection
When the induction cooker is in wor-
king state, the cooker is taken out, the
diameter of the bottom of the cooker
is less than 60mm, the material of the
cooker is not suitable, the heating will
be stopped, the power display will show
“
E
”, the timing display will show “
E1
”,
and if it is not recovered within 60s, it
will automatically shut down.
Overvoltage anomaly
When the induction cooker is in wor-
king state and the voltage is >270V±5V,
the heating will be suspended imme-
diately, the power display will show “
E
”,
and the timing display will show “
E3
”.
If the voltage is <260V±5V for more
than 1s, the operation will resume au-
tomatically. If the voltage is ≥260V±5V
within 10s, the buzzer will give out two
long and four short beep prompts every
5 seconds, and the alarm will be cancel-
led after about 90s or according to the
temperature of the
Lapitec
®
plate that
is lower than 60 °C.
Low voltage anomaly
When the induction cooker is in wor-
king state, the voltage is ≤ 160V ± 5V,
heating will be suspended immediately,
power display will show “
E
”, the timing
display will show “
E2
”, if the voltage is
