Electronics Box Mounting; Electrical Connections - O. Thompson Microflite Ultra 2000 Installation & Adjustment Manual

File, sand or lightly grind the area where the sensor will be located to remove any paint. Lay
the sensor on the cleaned area of the crosshead about ½" away from the edge. Shine a light
behind the sensor to ensure that it lays flat on the crosshead. If light can be seen under the
sensor, file the area until the sensor lies perfectly flat.
Locate the sensor ½" in from the outer edge of the crosshead channel. The sensor should be
mounted so the wiring connection is facing toward the center of the crosshead. Also, make
sure the edge of the sensor is parallel with the edge of the crosshead channel.
Mark the crosshead where the hole closest to the center of the car is located. Carefully drill a
9/32" hole at this point. Locate the position where the hole next to the first one must be drilled.
Carefully drill this hole. Loosely install the mounting bolts in these holes. Mark the location of
the last two holes. Remove the sensor. The last two holes should be drilled using an 11/32"
drill bit. Carefully drill these holes.
Loosely mount the sensor to the crosshead. It should be able to move slightly in the mounting
holes. If not, lightly ream the holes so it can.
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. Erratic operation may
occur if the bolts are not
tightened flat against the
sensor.

Electronics Box Mounting

9.1.3
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 the knock out provided. Coil any
excess cable inside the box. Tighten the nylon nut onto the strain relief.
