Aligning the Read Head
An integrated alignment aid is available to help you align the Y and Z coordinates of the read
head easily and precisely with respect to the code reel.
The switchover from normal operation to parameterization mode is via button 1 on the back of
the read head.
Activating the Alignment Aid
1. Press button 1 for longer than 2 seconds.
LED2 flashes green for a recognized code reel. LED2 flashes red for an unrecognized
code reel. .
2. Align the Z and Y coordinates of the read head. The integral LED indicators provide
assistance here.
Z coordinate:
If the distance of the camera to the code reel is too small, the yellow LED5 lights
up. If the distance is too great, the yellow LED5 goes out. The yellow LED5 flashes at the same
time as the green LED2 when within the target range. .
Set the distance between the read head and the code reel so that the yellow LED5 and the
green LED2 flash synchronously.
Y coordinate:
If the optical axis of the read head is too low relative to the middle of the code
reel, the yellow LED4 lights up, . If the optical axis is too high, the yellow LED4 goes out. Within
the target range, the yellow LED4 flashes at the same time as the green LED2.
Set the optimal height of the read head relative to the code reel so that the yellow LED4 flashes
in rhythm with the green LED2.
Briefly pressing button 1 ends the alignment aid, and the read head returns to normal
operation.

Parameterization of Fieldbus Address and Baud Rate
Before the read head can communicate with the CANopen fieldbus, you must set the
fieldbus
address
and
baud rate
parameters.
Parameterization using Code Cards
During external parameterization, the read head scans the special code cards optically and
configures the relevant parameters. Simply hold the corresponding code cards at the correct
distance in front of the lens on the read head.
Note!
The activation of the alignment aid is possible only within 10 minutes of switching on the read
head.
