facing down. Hold the bend securely against the edge of the crosshead, and clamp it in place.
Using a 3/8" drill bit, drill two holes through the template where the pilot holes are located.
After cleaning all shavings, remove the template from the crosshead. File the crosshead to
remove any burrs.
Referring to the figure below, install the sensor to the crosshead using the supplied hardware.
The bevel washers are installed under the lip of the crosshead so the mounting bolts are not
tightened on an angle. Tighten the bolts to 20 - 30 ft/lbs.
After the sensor is installed, the drill template will be installed on top of it as a guard. Place the
template over the sensor and secure it to the bolts with the supplied acorn nuts. The bolts
must only be loosely tightened. If they are too tight the sensor will not operate properly.

Electronics Box Mounting

9.3.3
Mount the blue electronics box in close proximity to the sensor. If possible, mount it so
adjustments can be made while standing on a landing. This is not critical, but makes the
adjustment procedure easier.
After the box is mounted, route the sensor cable through any of the knock outs on the
electronics box. Plug it in to the connector marked "J1." Coil any excess cable inside the box.

Electrical Connections

9.3.4
Refer to drawing on the following page for terminal locations.
Connect the AC power supply (controller terminals IP and IPX) to K-Tech terminals AC HOT

The output of the K-Tech unit will be connected to the O. Thompson Encoder power supply
board terminals J3-1 and J3-2. A twisted - shielded cable must be run from terminals LW+ and
