1.4 WOEC test programmes and their application
The control is provided with various test programmes, some of which can be switched
on manually or run automatically in the background.
Safety cut-out
The appliance is equipped with a safety circuit which switches it off automatically if the
allocated time intervals are exceeded at various temperature settings without the
functions or temperature setting being changed. This time interval is smaller the higher
the selected temperature.
Examples: up to 250 °C 3 h
up to 230 °C 6 h
up to 120 °C 12 h
Self-test
The automatic test programme which runs permanently in the background carries out a
self-test at regular intervals to monitor for correct operation of the appliance. If any
deviation from the specified parameters is detected during this test, the service symbol
and a 3-digit service code are shown in the display.
In addition, the appliance is switched on via safety relay K60 and the cooling fan via
K61.
The cooling fan cannot be switched off on the appliance as long as the above-
mentioned self-test detects the fault. The only possibility of switching off the cooling fan
is to remove the fuse in the house electrical installation.
Service test
The manual test system for the control comprises 6 test programmes. Access to these
6 test programmes is only possible if the control is in a fault mode and displaying the
current fault or the time is flashing.
This is achieved directly after connecting a voltage. If the test programmes are to be
accessed during operation, the appliance must be disconnected from the mains for at
least 10 s.

Descriptions of programme 1 - 6
Basic setting
1 - Time flashes or current fault is displayed.
2 - Press quick timer button and button I simultaneously and keep pressed for 5 s.
3 - The programme number appears in the right of the display and can be set to
1-6 using the quick timer button.
If the programme number has been preselected and no entry made for 5 s, the
control switches to the preselected test programme.
4 - Once a test programme has been executed, this programme can be quit by
pressing the Off button.
5 - See 1 for switching on the test programme.

Programme 2
In this programme, the individual relays in the relay unit can be switched on and off by
pressing the quick timer button. The relevant relay can be selected by pressing the
Cooking time and End of cooking time buttons at the same time. Max. 10 or fewer
relays can be selected, depending on the assignment.
Attention! If the load is switched on, the switch-on time should be kept short as
neither the cooling fan nor the hot air ventilator are running and
excessively long switch-on times can cause damage.

Programme 3 shows the temperature of the oven sensor and the food thermometer (if
inserted).
Note! The two temperatures normally differ because different measuring points
are used.
Programme 4 - see basic setting 1 - 5
If the power supply is disconnected after detecting the fault, the information is deleted
and fault code 000 appears on executing test programme 4.
If a fault has been detected but the cause of the fault no longer exists (temporary fault)
because the temperature has dropped or the cooking thermometer has been
disconnected from the socket, the relevant fault code is stored in the memory and can
be read out via test programme 4 as long as the power supply is not disconnected.

Fault reports for programme 4
Functional description:
When this module is activated, it handles all the faults present and carries out an
EEPROM check. As soon as a fault occurs, a fault register has access to the main
processor control loop. This causes the control to switch from the current status to the
fault mode (except when in the test mode): If a new fault occurs which has a higher
priority than the preceding fault, only this higher fault code is displayed. The last fault
occurring with the highest priority is stored and can be displayed by Service Test Mode
4 at any time. The fault with the highest priority is the EEPROM control fault »F«.

Fault-finding
Fault-finding is simplified by fault code test programmes. Faults which do not constitute
a direct danger to the user are not detected by the control, e.g. disconnected heaters.
The test programmes still provide help in fault-finding, even if the faults are not
detected.
Fault-finding using fault codes
Note! Fault code 003 can also appear for an incorrect switching
sequence. To switch back to normal operation, first press the O
button and then the I button.
