DISPLAY
CODE
F101 Door lock sensor alarm:
- if the door has to be locked but the feedback is unlocked
and temperature is lower 350°C
- or if door has to be locked and door is opened and sensor
temperature is above 300°C by pyro or 350°C by normal
oven function. At temperature above 380°C a F5 alarm will
follow.
F102 Door lock actuator:
Voltage of the feedback signal does not change during
un/locking.
-> 40sec lock - 80sec break 40sec lock – 80sec break 40sec
lock.
F203 Configuration checksum alarm OUI
Wrong checksum of OUI flash memory or bad SPI-bus
communication. Not detectable on the OC.
The OUI switches off the oven and displays error code F3
permanently.
F194 PT500 out of range warning:
If the PT500 value is out of range [400...1607.5 Ohm] for
more than 5 sec the alarm code appears.
F104 PT500 out of range alarm:
After 5min with PT500 warning (F94/F194) the OC switches
off the APD and the PWM and the alarm code appears.
F105 PT500 too high temperature alarm:
If the sensor temperature is
- over 380°C and unlocked door
- over 520°C and locked door
- if temperature is >370°C , F105 is set directly also if door is
locked but opened (Door lock with hook on).
F195 NTC (Board temperature) too high temperature alarm:
If the board temperature is over 105°C [<1KOhm] the OC
sends the alarm message. Oven operate normal only cooling
fan runs with max. speed. If NTC value is inside defined
range the failure is automatically reset.
