1. Gantry
2. The PCB camera
The PCB camera is located on the underside of the
gantry, on the head mount.
Removal
Fig.159: Vision board
► Unplug the two connection cables X2 and X6(1)
from the VHI.
► Unthread the two cables as far as the PCB cam-
era.
Fig.160: PCB camera
► Remove the four screws (1) holding the PCB cam-
era. Mark their positions to make clear assignment
easier later on.
Installation
► Install the new PCB camera on the mount. Secure the screws with Loctite 241.
► Run the connection cable to the VHI and reconnect to the electrical system.
► After replacing the PCB camera, you will need to recalibrate the machine zero point and the
camera offset. Use the relevant software function in the Service menu.
