NOTICE
The position of the IR sources in their housing has to be as shown in the graphics A and B.
Correct:
Wrong:
Fig.

: IR sources in their housing
If the position of a source is wrong, the radiation reaching the IR sensor is lower than when the
source is in the right position. It may happen that after transportation due to a strong shock that
the base lines are not in the right level due to the sources being not in the right position any
more. For correct base lines see chapter “Infrared cell adjustments”.
(Take care in case of previous IR cell models having a base line around zero volts.)
For correcting the position of bent IR sources use a thin forceps or carefully push them to the
right central position by using a thin screw driver. Take care not to bend the wires too far. They
are quite hard so that when bending back and forth they may break.
In case of changing a source, the wires must be very properly soldered because the resistance
of a source is below one Ohm.
All IR sources for all available cells in a module are connected in series.
For adjusting the IR source voltage see chapter “IR-source voltage setting”.

Motor replacement:
The replacement motors are supplied with their wires already soldered on a 9-pin plug, so that
in case of replacing a chopper motor, only the two wires of the IR sources have to be soldered
on the connector.
