7.3 Service test

Test routines and their use

The control is equipped with several test routines which can be run partly manually or are running
automatically in the background.

Safety switch-off

The appliance is equipped with a safety switch-off which leads to an independent switch-off of the
appliance, when with different temperature settings the assigned time intervals are exceeded without any
changes of functions or temperature.

Examples: up to 250 °C 3 h
up to 230 °C 6 h
up to 120 °C 12 h

Service test

The manual test system of the control is composed of 6 test routines. To have access to these 6 test
routines, the control must be in an error mode and indicate the current error, or the time has to flash. This
will be achieved, when voltage is applied to directly. When it is necessary to have access to the test
routines during operation, the appliance must be disconnected from the mains for at least 1 0 seconds.

Basic setting

1 Time is flashing or current error is indicated.

2 Keep key minute minder and key 1 pressed simultaneously for 5 sec.
3 The display shows the routine number at the right, which can be set from 1-6 using the key minute
minder. If the routine number has been pre-selected and no entry is made within 5 sec., the control
switches to the pre-selected test routine.
4 If a test routine has been carried out, this routine can be left by actuating the OFF key.
5 Switching on a test routine, see 1.

When the power supply is interrupted after the detection of the malfunction, the information is cancelled
and with the execution of the test routine no. 4, the error code 000 appears. If a malfunction has been
detected, but the reason for that malfunction does not exist any longer (passing malfunction), as the
temperature dropped resp. the cooking thermometer was plugged off, the error code is noticed in the
memory and, until the power supply is not interrupted, the respective error code can be read via the test
routine no. 4.

Error messages (routine 4)

Description of function:

If it is asked, this module handles all arisen faults and executes an EEPROM check. When a defect
arises, an error register has access to the main loop of the processor control. This results in the control
switching from the current state to the error mode (except when it is in the test mode). If a new fault
arises, which has a higher priority than the previous one, only the new one (higher error code) is
indicated. The last occurred fault with the highest priority is saved and can be indicated at any time by the
service test mode 4. The defect with the highest priority is the EEPROM check error “F”.

8.5 Description of function

After switching on, the relay K60 closes and the display shows the oven symbol. At the same time the
oven lighting goes on.
The cooling fan (relay K61) is switched on with a delay of three minutes.

After selecting the functions, following relays are active:

steam cooking K 68, K 62 K 69 below 80°C (K1,K2)

interval cooking K 68, K 62, K 65, K 66 K 68 and K 65 alternating (K1,K2)
hot air K 66, K 65 K 69 during heating phase
pizza level K 66, K 65, K 69
turbo grill K 64, K 65
infrared grill K 64
large area grill K 64, K 70
UH/LH K 69, K 70
drying K 70, K 65 K 70 clocks
lower temperature cooking K 66, K 65 K 69 during heating phase

K1 and K2: These two relays are used to select the actuators. When switching on a steam function, the
actuator A2 is applied to 230 volt and the steam vent closes (K1 and K2 under voltage). 5 minutes before
the end of the steam cooking, both relays K1 and K2 are switching. The actuator A2 is without voltage
and the steam vent opens. The actuator A1 is now connected with 230 volt and opens the devaporization
valve. After the time programme has run down, all steam components are without voltage again.

9.7 Further information

- As with the necessary mechanical processes there is the danger of injury by sharp sheet metal
parts, it is recommended to put on safety gloves.

- When you get a spare part with new seals when exchanging defective components, it is absolutely
necessary to exchange these seals too.

- The installation of the appliance (assembly and electric connection) is only to be made through
specialised stuff.

- The utmost caution is advised when opening the oven door to check the cooking food during steam
cooking, as hot and damp steam will leave the cave when opening the door.

Attention! With interventions in the appliance observe the safety rules!

9.8 ESD – electrostatic discharge and its effect on the control

As the interface of the control unit is open, the service technician, in case of a repair, has to pay attention
that there will be a balance of potential via the casing of the appliance (touch it) to neutralise possible
charges and not to damage the control unit. The same attention has to be paid to the service control
which should only be taken from its ESD protective foil, after there was also a balance of potential at the
appliance, before assembling the unit.

Note:
This is not to inform on the theoretic backgrounds of charging and discharging processes – they are
simply not interesting in this case. The practical effects are more important. We can experience (feel)
them every day, when there is a charge balance if touching a door handle.

What happens during a charge balance with the semiconductor components (part of an electronic
assembly)?

The charge balance occurs via the inner structures of the component. A component must not necessarily
be damaged immediately; much worse are possible later failures due to damaged inner connections
which arise only when loaded by temperature or power.

On the one hand, however, almost all sensitive semiconductor components (e.g. MOS circuits) have
been improved by integrated protective measures, on the other hand the inner structures of such parts
are today essentially smaller than, for example, 10 years ago, which in turn increases their sensitivity.

Attention:
Which components are endangered in case of services?
All components which have checking / control inputs (door switch, food thermometer ...), open conductor
paths and free accessible processors.

Concrete examples:
- timers with inputs for food thermometer and door switch
- timers, the control processors of which can be touched (for reasons of cost casing only formed as
half shell)
- WOEC control unit
