Connecting the sensor cables
You should not install sensor and power sup-
ply lines together, or lead them through the
same feedthrough. This can lead to interfer-
ences in the electronics, such as
"fl uttering"
in the relays. If it is necessary to lay the ca-
bles down together, or if the line is longer
than 3m, use a shielded sensor cable (4 x
0.5 mm²).
Connect the shielding to ground in the con-
trol unit.
Please observe that the following dimen-
sions relate to the values stipulated during
the unit inspection acc. EN 60335-2-53. The
heater sensor must always be installed at
the point where the highest temperatures
are to be expected. Illust. 7-9 give you an
overview of the mounting point of the sensor.
1. Mount the oven sensor in cabins up to 2
x 2m according to Illust. 7 and 9, in larger
cabins according to Illust. 8 and 9.

2. Drill a hole to lead the cable through, pref-
erably through the middle of one of the
wooden boards.
3. Lead the sensor cable through the drilled
hole and attach it to the sensor line ac-
cording to Illust. 10.
4. The cables for the limiter (white) and the
temperature sensor (red) are connected to
the sensor circuit board acc. Fig. 10. En-
gage the sensor board into the casing.
5. Lead the sensor cables through the
right cable intake into the control unit.
Install the sensor cables inside the
control unit as shown in Fig. 11.
Connect the sensor cables as shown in
Fig. 12. In order to do this, pull the plug
X2
from the circuit board and plug it back in
after the connection.
