CODE
F130(*)
Triac alarm:
If the power board (OC) is off and a failure at the triac fault
detection circuit is detected the alarm is set. The alarm can
only reset if the oven is plugged out/in.
F131 Steamer/Magnetron NTC Temperature sensor alarm:
If the NTC is for more than 5sec out of range [5°C – 295°C]
the NTC temperature is fixed on 140°C and the alarm is set.
The alarm is reset automatically immediately if the sensor is
in range again. This alarm can only happens if the oven is
configured as steamer or microwave oven. At streamer ovens
all heater elements are off. At microwave ovens only the
microwave loads(magnetron, stirrer magnetron) are off.
F132/ Door lock configuration alarm:
F232 This alarm is only possible at factory because the wrong
configuration is sent to the Power board OC. At pyro ovens or
ovens with door lock system the door lock activator has to be
configured on relay 6. If not configured on relay 6 then an
alarm is set. To reset this alarm a new configuration has to
send to the OC. If no door lock is configuration this alarm
cannot be occurred.
F133/ Data flash alarm:
F233 If the initial or write or read process on the flash failed the
alarm is set. If the failure happens turning start-up so only a
Restart can clear the failure. If it is a write or read failure the
failure will be reset with the next correct write or read
process. This alarm has no impact on the loads.
F134 AD converter Reference alarm:
For safety reasons it is necessary to check the multiplexer of
the analog- digital converter. This is done with a resistor. If
the value is not within the range [0.25V..0.65V] an alarm is
set and the pwm is switched off. If the value is within the
range again the alarm is reset.
F135 Electronic clixon alarm:
The OC has a protected relay that at temperature over 380°C
is disabled. The supply voltage of the relay is checked. If the
voltage is too high(>2.5V) for off state an alarm is set
immediately and the pwm is switched off. The alarm is only
reset if the voltage is in range again and the temperature is
lower than 380°C.
(*) NOTE: The code F130 also appears in case of convection fan motor failure resulting in failure to
the PWB.

DESCRIPTION
36/47
TROUBLESHOOTING
1. Check the resistance of the
motor convection fan.
2. Power board (OC) fault.
NTC Temperature sensor fault.
Wrong software configuration.
Check the compatibility of the
Power board (OC), Power
board probably wrong.
If the code F133 Power board
(OC) fault.
If the code F233 User interface
(OUI) fault.
Power board (OC) fault.
1. Check that the mains voltage
is correct.
2. Installation problems.
3. Fan operation.
4. Power board (OC) fault.
