9.3 Horizontal Laser
CAUTION
1.V0075
• Don’t look directly into the Laser beam.
Fig. 19: Horizontal Laser
Now the horizontal Laser for sensing the position of the crucibles is continuously ON. This can
be seen by looking at the sensor in front of the Laser.
If the Laser is ON and there is no beeping to hear, it means that the sensor is sensing the Laser
beam. For this, make sure that there is no crucible or anything else between the Laser and the
sensor preventing the beam from reaching the sensor.
Interrupt the beam between the Laser and the sensor to verify the correct functioning of detector
and beeper.
If the Laser is ON and the beeper is beeping, although the beam is not interrupted, this means
that the beam doesn’t hit the sensor. The beeper signalises this condition. In this case the Laser
should be mechanically adjusted so that the beam will be in the middle of the sensor. In case of
proper adjustment the beeper will stop beeping.
The adjustment is made by loosing the screws ( S1, S2 )and by turning and moving the Laser
until the beeping stops. If necessary, pull up or press down the blade for vertical adjustment.
NOTICE
It is very essential to adjust the Laser for the whole beam to reach the detector. If you
see a part of the beam hitting the aluminium detector housing around the detector’s hole,
readjust until you don’t see any Laser radiation on the aluminium housing.
