Replacing Antennas
Sensors
The GS series sensor antenna (part number TA011) is identified with a blue strip. The TA011
is replaceable.
Slightly damaged antennae (bent, sheathing scratched, plastic head cap
missing etc.) should not be replaced unless otherwise identified as preventing
proper sensor function. Heavily damaged antennae (ripped out, sheared off,
wire exposed and fraying etc.) should be replaced to ensure communication
between the sensor and the cabin mounted display unit.
The following items are necessary to successfully replace the sensor antenna:
a new antenna with white nylon hex bolt
a small pair of pliers
an electrical insulating compound
Place the crane, boom, jib or ball hook such that the sensor is safely accessible.
This procedure may be followed without removing the
sensor from the crane only if it is safe to do so; avoiding
removal and reinstallation procedures may save time. If
removed, an angle sensor must be re-calibrated during
reinstallation for correct angle display (see the angle sensor
installation section of the user manual).
During this procedure the interior of the sensor must be
protected from dust, grime and water at all times. If it rains
during the procedure an umbrella or other suitable means of
protection should be used.
Clean dust, grime and water from the sensor.
Identify the short black whip antenna and the white hex bolt
securing it.
Inspect the antenna for signs of obvious physical damage.
Carefully unscrew the white nylon hex bolt completely and
slide it up the antenna.
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.
Slide the white nylon hex bolt to the middle of the length of
the new antenna.
