Component data 4.1 Interface (input electronic display system) comfort class Fig. Interface comfort class The interface accommodates the components for entering and displaying the baking oven functions and the baking oven temperature. 4.2 Interface (input electronic display system) top class Fig. Interface top class Interface The interface accommodates the components for entering and displaying the baking oven functions and the baking oven temperature as well as the clock functions. 4.3 Power board of comfort class (baking oven) Fig. Power board of comfort class TSE-N A. B

10 4.4 Power board top class (baking oven) Fig. Power board of top class The power boards accommodate the components to control the heaters, hot air blowers, cooling fan and the automatic door lock (with pyrolysis appliances). In addition, the primary side of the power pack includes the fuse (sluggish, 100 ma) of the appliance. If this fuse is defective, the appliance does not function and the displays and lighting system are out of service. 4.5 Power board (hot plates) Fig. Power board of hot plates The power board accommodates the components to control the hot plates, other semi-conductor elements and a fine-wire fuse (sluggish, 100 ma). The hot plates cannot be operated if this fuse is defective. TSE-N A. B

11 4.6 Display of hot plates Fig. Display of hot plates These components accommodate the LED to display the cooking levels set at the 4 hot plates. 4.7 Set value transmitter (hot plates) At the set value transmitter, 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. Control is via the power board. Fig. Set value transmitter (function and temperature) 1 = 5 V Fig. Temperature controller TSE-N A. B

12 4.8 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. Fig. Temperature sensor Fig. Electrical resistance of sensor depending on the ambient temperature TSE-N A. B

13 4.9 Appliances with pyrolysis 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).

14 Fig. Door lock in unlocked state 2 E Inlet unlocking 4 Inlet lock 3 Phase (230 V) 33/34 Switch contacts (5 V, 100 ma) unlocked interlocked 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. TSE-N A. B

15 4.9.2 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. Abb. Micro switch TSE-N A. B

24 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. The fan after-running is controlled electronically with all appliances. In appliances with pyrolysis, a resistor is installed additionally (figure 1). The resistor is bypassed during the pyrolysis operation. Because of this the cross-flow fan is running at an increased speed, as long as the function is in operation. Fig. 1 Resistance increased speed r20.- resistance m2 - cross flow fan TSE-N A. B

28 7.2 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 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. Abb. Measuring the temperature sensor TSE-N A. B
