F136 Food probe configuration alarm:
If food probe is configured and not detected after start-up an
alarm is set. The alarm has no impact on the loads. Food
probe temperature is not valid (not updated)! This alarm can
only be reset with restart.
F236 Alarm due to the software bug :
This alarm occurs due to the bug in the software. Which is
fixed in the software update
F137 Food probe communication alarm:
Food probe module was detected and the oven is on but
communication is lost for more than 15sec. an alarm is set.
This alarm is reset automatically if the communication is
there again or if the oven is switched off. The alarm has no
impact on the loads.
Only food probe temperature is old or zero (short circuit).
F138 Fix sensor detection alarm:
For safety reasons it is necessary to check the oven sensor
that it's working. If the oven sensor does not change, if the
oven is on, alarm is sent and the PWM signal is switched off.
This alarm is reset automatically after 4 minute if the oven is
off (switching on/off is refreshing the 4min).
F239 Quantum Touch Controller alarm:
1. If the communication over the bus SPI with the
Quantum touch is after 50 trials unsuccessful than
alarm is set. The alarm is reset if the communication
is okay again.
2. If an incorrect ELC is used for a configuration of the
naked electronics or a configured spare part :
This error occurs due to different electronic software
between User Interface and touch electronics
F241 Function selector not connected alarm OUI Hexagon:
If the function selector is not connected for a time longer than
10 sec. the failure will be displayed and system off command
will be sent to power board. The failure will be detected if +5V
is on the micro input for function selector.
Failure indication is independent of oven state. This means
the failure code F241 will be displayed as long as failure is
active. After the re-establishment of the connection the OUI
displays "---°C" timeout if function selector is not in zero
position else ToD. If timeout symbol is in display user has to
switch first to zero position before selection of an OVF.
