4.11 Mains voltage components (casing removed)
Convection fan: motor
The convection fan motor is a 3-phase AC motor having a maximum speed of 5000
rpm controlled by a motor speed controller.
The windings are thermally protected and in the event of a thermal fault a trip
inside the motor will operate and shut down the motor speed controller.
Convection fan: motor speed controller
The convection motor speed controller provides a 3-phase AC switched mode drive
to the convection motor and is controlled by a digit signal from the SRB.
This allows the motor to be adjusted from approximately 1800 rpm to 7000 rpm in
steps of 10%.
Door open, 1800 rpm (7%).
Door closed (not cooking), 2150 rpm (17%).
Door closed (cooking), speed as specified by program or setting up to a maximum
of 5000 rpm (100%).
Convection fan: LED status display
Inverter Off / No supply, LED OFF.
Power On / Ready, LED ON continuously.
Inverter Running, LED ON continuously.
Fault Condition, LED flashes ON/OFF 3-9 times per second.
