7.2 Test of doorlock
Activating
To enter into door lock test the operator must execute the following actions:
1.
Power on the oven with oven function knob not in 0 position (oven goes to OVEN-SAFE
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 nor-
mal 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.
