10.10.4 Important clarifications

Sketch out the reading situation and enter the parameter values and variables for the CLV.

Determine the reading range and installation height of the CLV above the conveyor belt:

With a covered conveyor belt with a 600 mm width, the CLV can read an object at a di-

stance of 600 mm (according to the reading field diagram in

Fig. 10-1, Page 10-3

). For

a reserve of an additional 100 mm and a maximum package height of 600 mm, the re-

sulting reading range of the CLV can be set to 700 ... 1 300 mm from the reading window.

The CLV is to be mounted 1 400 mm above the conveyor belt, as the package must be

at least 100 mm high.

Determine the CLV’s distance measurement type:

For the required total field depth range of 600 mm, a height detection of the focal po-

sition changeover is required. This is carried out by activating the CLV’s direct distance

measurement (the basis of the autofocus function).

10.10.5 Mounting and electrical connection

1. Mount the CLV centered 1 400 mm above the conveyor belt (vertically) according to

Fig. 10-44

, reading window facing downward.

2. Align and screw in the CLV in a reading axis with the reading window at a 10

angle

against the required reading direction as shown in b)

Fig. 10-44

The CLV can carry out a distance measurement from the front of the package to the

top of the package while it is in motion.

3. Attach the pulse photoelectric switch and reflector to the conveyor belt so that there is

a distance of approx. 100 mm between the photoelectric switch and the scan line

position on the package with the smallest height.

4. Connect the CLV to the AMV/S 60 connection module.

(

see Chapter 5.2.3 Connections/cables for the AMV/S Connection Module, Page 5-3

)

5. Connect the pulse photoelectric switch to the AMV/S 60 connection module

(see

Chapter 5.5.7 Connecting the switching inputs, Page 5-16

6. Turn on the supply voltage to the CLV.
