Orientation of the
limit distance line
Setting instructions - Sequence
Move the crane to the limit distance
Illuminate the edge of the reflector with a lamp
The front surface of the transducer bench can be seen if
the lid is opened or with JH1 through the lenses of the lid
is closed
Projection of the edge of reflector must be detected
as a light image
Move the light barrier around the „D“ axis of rotation. The
fixing borehole for the „E“ slot should be in the central
possiton of the slot

Reflector image in accordance with

Screw the light barrier tightly in this position
Pre-set the spring-supported screws A, B and C to a
spring spacing of approx. 18 mm
Use the „C“ regulation screw to conduct the
horizontal alignment Achieved if the reflector height is
centred towards the borehole height
Select the mounting position so that the center of the
optical system and center of the reflector are at the same
height
Fine alignment:
Turn the device around the „D“ screw
testing the set clearance, lock the adjustment flange with
the mounting surface by using the supported spring dowel
sleeves „F“ against shifting by bumps
Transducer boreholes cover the edge
of the reflector up to the point at which
the two green LEDs go out.
Before commencement of work, the system’s
safety function has to be checked by moving the
cranes together (daily functional check)
A correct assembly and alignment
of the system are essential for the
correct operation of the system’s
safety function!
Mount the reflector close to the edge of the railing!
The tolerances in the distancing accuracy must be taken into account by
adding them to the clearance distance!
Case example 4R100BL –reflector width 400 mm:
Planned distancing = 15 m, triangulation angle 1,5°.
Maximum tolerance in accordance with diagramm fig. 4.4.3 = 7% == 1,1 m.
Minimum distanciing to be set = 16,1 m + movement tolerance.
