Working principle.
A transformer is used to be able to switch the 2 blo-
wers on low speed (165Volt) or high speed (220Volt).
Blowers “Power ON” sequence.
The blowers are switched on by the relais on output
X6.
Blowers “low speed” sequence.
In case the blowers are set on low speed in the cook-
ing program, the blowers will start up in high speed as
explained above. After 10 seconds, X6 opens, X5 opens
and X4 closes followed by “Power ON” (X6 on).
Passive measurements
(resistance and capaci-
tance)
Disconnect the mains supply first!
The Blowers.
• The overview shows how the coils are connected
to the terminal block on the back of the blowers.
• It also shows the connections between the contacts
on the terminal block itself.
Measuring the blower coils.
Disconnect the feedwires on the screw terminals first!
Main coil:
33 Ω. Between Black and Blue
Start coil:
45 Ω. Between Brown and Blue
Both coils:
78 Ω. Between Black and Brown
Insulation test:
∞
MΩ between a terminal and
ground.
2,42 Ω can be expected when measuring on the screw
terminals (black and blue)in case they are NOT discon-
nected. This is because of the transformer coils.
