NOTE: A/D refers to the analog-to-digital conversion of the
sensor reading.
If the reading is below 750, or there is no reading at all
follow these steps to exert a pre-load on the sensor:
a. Loosen the nut on the non-cable end of the sensor.
b. Insert a wedge (i.e. a flat-blade screwdriver) under
the non-cable end of the sensor until an appropriate
A/D reading is reached, for example:
Steer
– 1000 (±250)
c. Tighten nut on non-cable end of sensor to 25 ft-lbs. If
A/D readings are still within range, remove wedge
and check A/D readings. Proceed with Step 30.
If the reading is above 1250:
d. Loosen the nut on the non-cable end of the sensor.
e. DO NOT WEDGE the sensor, lightly press on the top
of the non-cable end to change A/D reading.
f. Tighten nut on non-cable end of sensor to 25 ft-lbs.
Check A/D readings; if they are below 750 repeat
Steps 31 a - c. If they are above 1250, repeat Steps
31 d - f. If within range proceed with Step 32.
If using the Deflection Sensor Test Device: Before
connecting the sensor to the sensor extension cable, check
A/D readings and adjust if necessary at this time according
to Step 37 (see page 27). Otherwise, proceed with next step
of installation.
