Function

2.1

Safety Cutoff

If there is an error in communication between control electronic 2N1 and
power electronic 1N1, safety relay K1 is activated and relays 1 to 4 of the
power electronic are cut off. Both heater elements and the magnetron are
switched off via relay K1.
Thermostat 1F1/1 (275°F) at the magnetron wave guide monitors the oven
cavity temperature. At excess temperatures, safety relay K1 is activated,
which switches off both heaters. Because of the distance to broil heater R15,
the cutoff temperature is set correspondingly low.
If convection fan M2/2 is defective, the safety cutoff of convection heater R14
is activated via thermostat 1F1/1 (248°F) at the rear of the oven cavity.
Because of the distance to convection heater R14, the cutoff temperature is
set correspondingly low.

Heater Element Timing

In operating modes microwave + broil and microwave + convection plus,
broil heater elements R15 or convection heater elements R14 are switched in
sequence and not switched on at the same time as the microwave.
