1 SAFETY 1.2 Repair instructions

Caution! 1.1 Safety instructions

Danger! NEVER attempt repairs by randomly replacing components! ALWAYS proceed systematically and comply with the technical documentation for the appliance! Repairs may be carried out only by customer service engineers

trained by the manufacturer! As a rule, printed-circuit boards are not repaired but are completely replaced by original spare parts. Exceptions are documented separately.

The user may be put at considerable risk and injured by improper repairs!

If the appliance is faulty, the housing or frame may be live! Do not touch components in the appliance. Even the modules can be

live! Electrostatic sensitive devices: Comply with ESD information (see “General repair instructions”)!

Before commencing repairs, ALWAYS disconnect the appliance from the power supply! If tests have to be conducted while the appliance is live, ALWAYS use a residual-current-operated circuit-breaker!

The protective conductor connection must not exceed the standardised values! This is essential for personal safety and appliance function! Sharp edges:

Wear protective gloves! When repairs are complete, conduct a test in accordance with VDE 0701 or the corresponding national regulations as well as a performance test!

Procedure: Note: When automatic boil start control is activated, the power is increased by four settings, starting from the preset simmer setting. However, this is possible up to max. simmer setting 5 only. At higher settings this simmer setting is reduced correspondingly. At power setting 9 no further increase is possible.

Switch on appliances with the main switch Important: - no active timer mode.

- all hotplates on “0”. Actuate sensor “0” and “1” simultaneously and permanently. A signal is emitted.

4 COMPONENTS The control and main electronics modules are fitted together and can be ordered as a spare part only. 4.1 Electronics module The heating elements operate in switching mode by means of triacs synchronous to the mains voltage at their zero crossing. The clock pulse period is within the millisecond range. Therefore, the “clocking” of the heating elements cannot be observed with the naked eye. Rather the heating elements seem to illuminate at a different intensity depending on the heat setting.

New control electronics module CK 596-115/1 The infrared sensors are installed in a plastic holder

Old control electronics module CK 596-115 The infrared sensors are held together by a steel spring

Main electronics module CK 596-115

Page 9 of 17

4.2 Heating elements 4.1.1 Residual heat display

The residual heat is not displayed via the temperature contacts, but is calculated by the electronics module based on the ON duration and the selected heat setting. As a result, particular consumer habits do not affect the display duration (e.g. hot oil pan left on the plate)

4.1.2 Overheating protection system

The electronics module features an overheating protection sensor. If the critical limit temperature is exceeded, the front and rear right cooking zones switch off “H” and the residual heat display are indicated alternately on the corresponding cooking zones. When the temperature drops below the limit again, the letter “H” goes out, however the cooking zones remain switched off. If required, they can be switched on again.

Super Quick cooking zones are installed (Hilight). These are distinguished by a uniform heat dissipation. After the heating element is switched on, the heat is throttled quickly at that point. On account of the high percentage of infrared light the heating coils are clearly visible as they heat up (similar to halogen heating elements).

4.1.3 Multiple operation

If two or more sensors are actuated simultaneously, the electronics module detects multiple operation and signals this by 5 “peeps” in rapid sequence.

The attached rod controller protects the glass plate from overheating (switches off at approx. 520 °C)

7. Check sensors by actuating them 6.1 Grey cards and finger calibration 6.1.2 Finger calibration

If hobs are older than FD8201, the electronics module can or must be calibrated. If a malfunction occurs or the glass plate is replaced, the sensors must be calibrated. In many cases a replacement of the electronics module can be prevented.

1. Press and hold down calibration button, signal emitted 2. Approx. 6 sec. after the 2nd signal, release the calibration

button 3. The timer display indicates “01”

4. Actuate the “front left zone” sensor until a signal is emitted 5. Remove finger. A signal acknowledges calibration of this

sensor. “02” is displayed 6. Repeat steps 6–8 according to the following table until “09” is

indicated on the timer display. 7. Calibration ends after the last sensor (09).

Acknowledgement by a double signal

Caution: from FD8201 the electronics module can no longer be calibrated (if the Options menu can be started, see 3.9, calibration is no longer possible).
