Heavily damaged antennas (ripped out, sheared off,
wire exposed and fraying etc.) should be replaced
to ensure effective communication between the
sensor and the cabin mounted display unit.
This procedure may be followed without removing the
sensor from the crane if it is safe to do so. If removed,
an angle sensor must be re-calibrated during
reinstallation for correct angle display (see the angle
sensor installation section of the user’s manual).
1. Place the crane, boom, jib or ball hook such that
the sensor is safely accessible.
2. Clean dust, grime and water from the sensor.
3. Identify the short black whip antenna and the
white hex bolt securing it.
4. Inspect the antenna for signs of obvious
physical damage.
5. Carefully unscrew the white nylon hex bolt
completely and slide it up the antenna.
6. Grip the antenna by the base of the black plastic
sheathing and pull it straight out of the hole in
which it is seated. Place the old antenna aside.
7. Slide the white nylon hex bolt to the middle of
the length of the new antenna.
8. Coat the exposed metal foot of the new antenna
with an electrical insulating compound by
carefully inserting it in the mouth of the
compound tube.
9. Hold the new antenna by the black plastic
sheathing and guide it through the hole in the
sensor box. Carefully seat the antenna in its
mating connector. When the antenna is
correctly seated, pulling on it will be met with
light resistance.
10.Carefully re-thread, screw-in and tighten the
white nylon hex bolt to secure the antenna in
place. Do not overtighten.
11. Reinstall the sensor if necessary (if removed
from the boom or jib, an angle sensor will
require re-calibration during the installation
procedure, see the angle sensor installation
section of the user’s manual).
12.Verify that the sensor functions properly.
