Installation
1. Note the orientation of the readhead on the scale. Be sure the arrow on the
readhead points towards the “BLACK END OF SCALE”. This orientation is critical
for proper operation of ProScale. Be sure the mounting location for the readhead
and scale will allow this orientation. Take care when sliding the readhead onto the
scale so the brass “fingers” inside the readhead do not get damaged. (A slight
“wiggling” motion when installing the readhead on the scale will simplify the
process.)
2. Determine an appropriate mounting location for the system. Most applications of
the Model 250 will have the scale held stationary while the readhead is moved
along the scale. However, the ProScale will read correctly if the readhead is moved
along the scale or if the scale is moved through the readhead.
3. When the scale is stationary and the readhead moves to measure, you should use
the Guide Clip to move the readhead along the scale (see figures on next page).
Mount the scale using M4 (or #8) screws. Be sure the screw heads do not protrude
above the surface of the extrusion. Check that the scale is
properly aligned as the readhead is moved over its length (the
Guide Clip will compensate for slight misalignment). Adjust scale
alignment if necessary.
For accurate measurements, the guide clip must be mounted
perpendicular to the direction of travel of the readhead. The guide
clip should exert some pressure over the full range of travel on the
readhead so the two move as a single unit.
Note: Failure to use the guide clip could void the warranty.
4. The Digital Display may be mounted in a location which allows for easy viewing by
the operator. The location of all parts should also safeguard the cable from
possible damage. ProScale wiring should be kept away from electrical wiring and
motors. Plug the readhead into the display. See Section 4: Digital Display
Operation
Note: If any other mounting method is used, observe the following:
A. Do not drill through the green portion of the scale at any point over which the
readhead will travel.
B. Do not mount the scale so the mounting hardware interferes with the
movement of the readhead.
