Mounting Rack And Mast For The Scanner; Scanner And The Surrounding Structural Objects - JRC JMA-3400 Series Instruction Manual

Chapter 1 INSTALLATION

1.3.3 MOUNTING RACK AND MAST FOR THE SCANNER

If it is considered that sufficient installation height cannot be provided when the scanner is installed directly on
the roof of the wheelhouse, use a mounting rack or radar mast (Fig. 1-3-3).
Normally, when the scanner installation height is less than 2 meters from the roof of the wheelhouse, provide
a mounting rack assembled at an angle frame to install the scanner. When the scanner installation height is 2
m or higher from the roof of the wheelhouse, provide a cylindrical radar mast to install the scanner.
Consider the convenience of the service staff who take care of installation, maintenance, adjustment and
repair of the scanner by providing adequate footholds to the mounting rack and the radar mast.
Installation
1.3.4 SCANNER
OBJECTS
When installing the scanner, select a location where there are the fewest structural objects in the surrounding
area so that false images which interfere with target detection will not be generated by signal reflection from
other scanners, deck structures, and cargo.
Only as a guide, note that structural objects should not exist within the range of the vertical beam width
(Fig. 1-3-4).
NKE-2043 Vertical beam width: Approx.25°
NKE-2063A/AHS Vertical beam width: Approx.30°
NKE-2103-4/4HS Vertical beam width: Approx.20°
NKE-2103-6/6HS Vertical beam width: Approx.20°
