FITTING NOTES
Transceiver and Turning Mechanism
11 The Antenna and Transceiver are specified and supplied separately (options are shown
on Chapter 1, Figure 1). Refer to Figure 1 for outline dimensions and fixing centres. The
following criteria are to be observed when installing:
NOTE: Assemble the two units together prior to hoisting into the installation position.
CAUTION
Do not remove the transparent film covering the waveguide outlet as this prevents the
ingress of water or moisture.
(1) Remove the protective caps, tapes etc. Ensure the waveguide faces are clean and
free from grease. Fit the appropriate ‘O’ ring. Fit the Antenna array to the
transceiver with the eight bolts, holding it loosely in position. DO NOT
TIGHTEN THE BOLTS. Refer to Figure 2.
(2) Align the waveguide from the Antenna to the Rotating Joint and fit the four
waveguide bolts. Do not force the waveguide to the coupling face. Tighten the
waveguide bolts evenly until the mating faces are flush. Torque load the Antenna
retaining bolts to 19 to 24 Nm (14-16 lb./ft).
(3) Hoist the Transceiver and Antenna assembly, (ensuring the slings do not foul
with the Array), to the mounting plate.
(4) Mount the Transceiver facing forward (removable cover facing aft). Fit the
retaining bolts and torque load to 50lb/ft (75kg/m) then gain access to the interior
by removing the rear cover.
NOTE: The outer casing of the Transceiver must be bonded to the ship’s superstructure using
a copper earthing strap connected to the earthing point shown in Figure 1.
(5) The connecting cable from the Transceiver to the Display should be kept to a
maximum of 60 metres. Do not exceed 60m without consulting the Kelvin
Hughes Technical Department.
(6) Fit the Monitor Arm (if supplied) onto the side of the casing and secure the clamp
with the four retaining screws. The monitor arm cable is passed through the
smaller cable gland and clamped. The cable screen is to be earthed by the ferrules
in the cable gland assembly.
