9.2 Vertical Laser
CAUTION
V0075
• Don’t look directly into the Laser beam.
Fig. 18: Vertical Laser
At this step the vertical Laser for sensing the home position of the arm is continuously ON. This
can be seen by looking at the sensor underneath the Laser.
If the Laser is ON and there is no beeping to hear, it means that the sensor is sensing the Laser
beam.
Interrupt the beam between the Laser and the sensor to verify the correct functioning of sensor
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. The
adjustment is made by loosing the screws (
S1,S2,S3,S4 )and by turning and moving the Laser
until the beeping stops. It is not enough if simply the beeping stops. Make sure that the beam is
in the middle of the sensor.
Press the adjust bottom (5) (see Fig.: Loader signal and control cable ) again for only about
one second to proceed to the next step
– horizontal Laser check.
