The angle sensor total range is approximately 105° and the zero point is adjustable in the software in
the angle calibration menu. With no software adjustment, the angle range will allow a -15° to 90°
range, but if the angle sensor is zeroed at -5° (-5° becomes 0°) your angle range will be -10° to 95°.
Therefore, when affixing the mounting plate to the boom, make sure you will be able to get your
desired angle range for your application.
1. Locate an appropriated flat surface area on the boom base section or luffing jib root section. Avoid
the installation close to moving parts or parts that could interfere during boom hoist up and down.
Lower the boom into position that will allow you to safely install the angle sensor.
Notes: The antenna must point down and not up. Do not install angle sensor on hot mounting
plate, temperatures greater than 125°F (52°C) this could damage the angle sensor and/or
transmitter.
2. Measure the boom angle by using a digital inclinometer (i.e. smart level) at the area selected in
step 1. Align the mounting plate as defined be the decal or so the mounting holes pointing down as
shown in the pictures above. Affix the mounting plate onto the area. Clean, prime, and paint the
mounting plate if necessary.
3. Remove the angle sensor cover by loosen the four screws in the cover. Check the gasket to insure
it is not damaged. Remove the batteries. Align the 4 holes with the mounting plate threaded holes
and screw the angle sensor onto the mounting plate by using the four screws supplied in the kit.
Attach the antenna to the connector by carefully rotating the antenna clockwise.
4. On the console, setup the sensor by using the menu selection:
MENU SETUP/SENSORS/ANGLE 1 or 2.
In the setup process you will be asked to insert the batteries while the receiver searches for the
transmitter. Install batteries correctly as shown on the label in the battery compartment. When the
sensor has been found, the angle sensor screen will be displayed. Inspect the gasket on the
battery cover for cuts or other damages, install and tighten the four cover screws.
OR
After making this selection, measure the boom angle by using a digital inclinometer (i.e. smart
level). If the angle displayed does not match the measured angle complete the angle calibration
next step. If the angle displayed matches the measured angle, go to step 6.
