MEASURING ON THE VENT MOTOR
Working principle.
Two end switches are mounted on the block
of the motor which give a signal when the
opened or closed position is reached.
These switches are directly connected to the
I/O board and therefore it has a low voltage.
The motor itself is 230 Volt.
The resistance is ± 160 Ω.
Note that it is good to know for test purpo-
ses that the valve will be opened when the
door is opened, and closed when the door is
closed.
MEASURING ON THE STEAM AND WATER SYSTEM
±3,5kΩ
±3,5kΩ
Depending on the model, the Bake Star can
have a single valve, double, triple or qua-
druple.
All valves have waterflow reducers mounted
inside. These reducers control the water-
flow for the steam production. An opened
valve will give ± 0,5Ltr/minute (0,13 gal-
lon/minute).
The valves are pulsating controlled, mea-
ning that they are opened many times
for a short period (0,1 - 0,6 seconds). See
chapter programming and also the steam
parameter settings.
Refer to the programming instructions and/
or the service manual I-control
The valves are indirect controlled. This means
that the water pressure is needed for the
closing or opening of the valve. Therefore
a minimum pressure of 0,5 bar is necessary
for a proper functioning.
From 2011, the water reducers are factory
mounted inside the valve. Loose reducers
however are still mentioned in the explo-
ded views but there is limited stock and
finally Fri-Jado will not deliver them any-
more.
