Temperature surveillance

Heat sink temperature

The temperature of the heat sink is detected by a

temperature sensor. The temperature surveillance turns

on an internal fan at 140°F to cool down the heat sink and

stop at 131°F. If the temperature exceeds 167°F, the unit

will reduce the power supply to the induction coil by it-self.

If the temperature exceeds 185°F the unit shuts down the

whole power supply and, on the display, appears the error-

code E03.

Ceran glass

The temperature under the Ceran glass is monitored

simultaneously by multiple temperature sensors. If

the temperature exceeds 248°F, the power output is

interrupted. The display will show the error code E04.

Internal temperature of the unit power board

The temperature of the heat sink is detected by a

temperature sensor. The temperature surveillance-lance

turns on an internal fan at 131°F to cool down the heat

sink. If the temperature exceeds 158°F, the unit will reduce

the power supply to the induction coil by itself. If the

temperature exceeds 176°F the unit shuts down the whole

power supply and, on the display, appears the error-code

E06.

Central unit

At 212°F processing temperature, the power output is

interrupted and E30 on the display.
