Travel Sensor Is Factory Adjusted




The placement of the feedback
arm on the travel sensor is
factory adjusted and sealed with
anti-tamper paint.
This setting has been tested for
functionality successfully several
times before the DVC6000 ships
from the factory.
Do not assume this setting is
wrong.
Check everything else first before
disturbing the anti-tamper paint.

DVC6200 - Mounting Kits


Bolt patterns for DVC2000 and DVC6200 are
identical
Existing DVC2000 mounting kits are being
updated
– 1 standard kit for both DVC6200 and DVC2000
– Stronger brackets will replace the existing brackets
to accommodate additional weight

New curved array
– For use with the existing long stroke cams
– For Fisher rotary actuator window
