Mounting Information...
These instructions are for mounting the SENC 150
encoder to the cross feed on a vertical knee mill.
Before proceeding:
³Please read the Procedure completely.
³Mount X axis prior to installing the cross feed.
³Clean the mounting surfaces.
³Save the alignment brackets with the Encoder
Reference Manual after installation is completed.
First Steps ...
Machine
Move the table to it’s far left travel.
Move the saddle to it’s center of travel, include
the longitudinal scale thickness.
Mark the axis so that it can be re-centered easily.
Encoder
Unpack encoder in a safe, convenient location.
Do not remove the reading head alignment
brackets until instructed.
Center reading head ...
•Mark the center location on the scale case. Slide
the reading head and brackets along the scale case
until the center marks on the scale case and
reading head are aligned.
