Install the Autofocus Lens and In-Sight Illumination
Complete the following steps to install the autofocus accessory (ISAF-7000-8mm) and illumination accessory (ISLM-
7000-WHI).
Note :
l
The autofocus module has an 8mm M12 lens pre-installed. If a different lens is required, it should be
installed into the autofocus module before the autofocus module is installed to the vision system. For more
information, see Replace the M12 Autofocus Lens (Optional) on page 61 .
l
For the In-Sight 7905, the vision system image circle is larger than the S-Mount/M12 lenses used in the
autofocus module (ISAF-7000-8mm) and the S-Mount/M12 adapter kit (ISLN-7000-SMNT), resulting in
mechanical vignetting in the image when using any S-Mount/M12 lens. Therefore, S-Mount/M12 lenses are
not recommended. For more information, see Mechanical Vignetting on page 110 .
l
The illumination accessory (ISLM-7000-WHI) is sold separately. It is the only cover available for the
autofocus module and is required for IP67 rating.
l
The vision system supports connecting an integrated illumination accessory to the vision system's faceplate
and connecting an external light to the vision system's LIGHT connector, but does not support using both
lighting devices simultaneously.
CAUTION :
l
When installing the illumination accessory (ISLM-7000-WHI):
l
Do not hot-plug the illumination accessory. Verify the vision system is not receiving power when
connecting or disconnecting the illumination accessory. Failure to remove power during this
procedure may result in damage to the vision system and/or the illumination accessory.
l
The vision system should be grounded, either by mounting the vision system to a fixture that is
electrically grounded or by attaching a wire from the vision system’s mounting fixture to frame ground
or Earth ground. If a ground wire is used, it should be attached to one of the four mounting points on
the back plate of the vision system and not to the mounting points on the front of the vision system.
l
Tighten all illumination accessory screws in the following sequence.
1. Remove the rubber faceplate covering the image sensor window, if present.
2. Remove the protective film covering the threaded lens opening, if present.
