4.1.2 Thermostat

Fig. Temperature values

Fig. Thermostat

The hot plates are controlled via the bimetallic contact P 1-2. The input voltage of 230 V is applied
here.
Depending on the position of the knob, this contact determines how often the hot plate is switched
on or off during a certain unit of time by cycling the maximum heating power (230 V or 0 V between
contact 2 and 4) (refer to performance characteristic).

Continuous operation at max. heating power is hot plate 9.

The power characteristic shows the power controller in cycling mode.
The average switching on period for each knob position can be read off in % of the cycled and/or
max. power.

The temperature can be selected according to the knob position.
After beginning of work, contact 1-2 is closed.
To check the thermostat, measure the temperature in the muffle. Determine the following
temperatures:

- Hot air 160 °C ± 15 °C

- Conventional 200 °C ± 15 °C

- Pyrolysis 485 °C ± 20 °C
If a temperature is found which is beyond the tolerance value, replace the thermostat.

4.2 Appliances with pyrolysis

4.2.1 Door lock

The appliances with pyrolytic self-cleaning system are provided with a specific door lock system
(Fig. 1) This system prevents opening of the baking oven door with the pyrolysis switched on. The
lock system is operated with 2 heated bimetallic elements which move a bar into position which
then either blocks or releases the lock lever at the baking oven door. The system functions during
the pyrolysis process independent of the electrical voltage.
The door lock is switched on at a temperature of the muffle centre of gravity (temperature in centre
of baking oven) of 312 °C. Unlocking is at a temperature of approx. 180 °C via a Klixon (f11 in wiring
diagram). The Klixon is arranged at the transverse beam beside the hot air motor (Fig. 2).

As soon as a voltage of 230 V is applied to the contacts 3 and 4, the bar A moves to the other side
after 2  10 seconds and blocks the lock lever mechanically. The door cannot be opened. At the
same time, the internal contact B opens and disconnects the lock path. The switch contacts 33/
34 close and signal that door lock is completed. The electronic signal completes the lock signal.
Internal contact C closes.
For unlocking, a voltage of 230 V must be applied to contacts 2 and 3. The bar A moves
backwards and releases the lock lever. The door can be opened provided that the contact f11
(Klixon) is closed.

4.2.2 Micro switch for telescopic runner

The appliances with pyrolytic self-cleaning system are provided with a micro switch. The switch
contact is interrupted with the grates suspended. Thus the self-cleaning function cannot be
activated. The contact closes and self-cleaning is possible with the telescopic runners removed.

4.2.3 Temperature and function controllers

Both with the temperature controller and the function controller, each angular degree of switch
turning changes an existing voltage value and/or resistance value. Thus turning the switch results in
a change of the existing temperature at the heater or of the mode of operation. Control is via the
Prisma basic power board.

4.2.4 Temperature sensor

The temperature in the baking oven is measured by a temperature sensor (type PT 500) for
appliances with control board. The sensor is provided at the rear of the appliance. It is used to
transmit to the electronic systems the values for:

- cyclic heating the radiators until the selected temperature is reached;

- switch off the radiators in case of overheating of defective sensor;

- switching ON/OFF the cooling fan.

4.2.5 Prisma basic power board

The Prisma basic power board controls the following range functions:

- Operation of radiators

- Operation of hot air blower

- Operation of cooling fan

- Optical display via signal lamps

- Automatic door lock during the pyrolysis process

according to values to be selected at the temperature and function controller. The Prisma basic
power board includes a power pack, 4 relays to control the heaters and other semi-conductor
components and a fine-wire fuse (sluggish, 63 mA).

Fine-wire fuse

The fuse is arranged at the primary side of the power pack. If this fuse is defective, the appliance
does not function and the displays and lighting system are out of service.

Important: Appliances with Prisma basic power board are not provided with a test program!

The supply voltage of 230 V for the power board and the consumers is applied at the main supply
connection.
For the other measuring points for small loads, door lock and heaters please refer to the block
diagrams.

6. Technical equipment

6.1 Fan running on function

The appliances switch on automatically as soon as the baking oven is started. After having
switched off the baking oven, the cooling fan continues to operate in order to cool down the
appliance.

Important: All appliances of this series are provided with this running on function.

Appliances without electronic
system, without clock: In these appliances the running on function of the fan is

controlled via a Klixon which is provided at the rear of the muffle.
Appliances without electronic
system, with clock: The control system of the fan running on function functions via a

limiter which is provided behind the baking oven switch in the

cable harness.
The fan running on function of all appliances with Prisma basic power board is controlled
electronically. As these appliances are also provided with a pyrolysis feature, an additional
resistance (Fig. 1) is installed which, however, is bridged during the pyrolysis mode. Thus the cross
flow fan operates at a higher speed as long as this function is active.

TSE-N 01.01 A. B. 599 50 86 62 EN

6.3 Measures to prevent wrong electrical connection

If a range with pyrolytic self-cleaning system is connected wrongly, the micro processor at the Pris­ma basic power board recognises this error. It changes over into the fault mode. The fault is
displayed by flashing pilot lamps in the switch panel. The heaters are dead. The connection error
can be corrected. Then the range can be operated quite normally.

6.4 Thermal link

A thermal link is provided in all appliances at the left side at the air duct, which switches off the
device in case of overheating.

TSE-N 01.01 A. B. 599 50 86 62 EN

7. Fault diagnosis/What to do if ?

7.1 Measuring the temperature sensor

If a failure at the temperature sensor is assumed, the resistance can be checked by means of an
ohmmeter.
The resistance of the temperature sensor should be 500  600 ohms at room temperature.
Make sure to measure the insulation resistance between the metallic housing and each connection
terminal.
The resistance should be higher than 2 MOhms.

Refer to chapter 4.2.5 of Prisma basic power board for failures of consumers and door lock.

state). It can exit from this state by setting oven function knob in 0 position (see Chapter ­EXIT PROCEDURE). Apart this position, in OVEN_SAFE the user can freely move knobs and
the oven does not perform any action.

2. Move oven function knob to oven function 9.

3. Move temperature selection knob to max position.

4. Move oven vunction knob to oven function 1.

5. Move temperature selection knob to zero position.

At this point the oven is in service mode (OVEN-SERV-TEST state). This information is displayed
to the operator by changing led status from OVEN_SAFE mode (Pilot lamp on, Temperatur lamp
blinking at 1 Hz) to another one that is pilot lamp blinking 1 Hz and temperatur lamp off.

Each one of the actions 3, 4 and 5 must be done in short time (10 seconds) after the previous
action. If the operator does not perform each operation within the time-out, the entering procedure is
aborted. At this point the oven remains in OVEN_SAFE state and it is possible to restart the
entering procedure from the action 2.

6. Move knov to position 2 to start door lock test.

Deactivating

Door lock test can bei paused moving the knob from position 2 to another position )different from 0
position).

If the operator moves the knob to 0 position, the oven exits from SERVICE MODE and goes to nor­mal OVEN-STD-BY state.

During SERVICE MODE, if the operator does not move the knobs at least every 5 minutes, the
oven automatically exits SERVICE MODE and goes to normal OVEN_SAFE state. In this way we
avoid the possibility that the operator leaves the oven in SERVICE MODE.

In any case of the oven is switched off the SERVICE MODE is cancelled.
