3.6.1 Mounting plate
The Merlin LT can be directly secured to a vessel using the holes in the base plate. Alternatively, the mounting plate
is supplied to offer more flexibility during the installation process.
The mounting plate can be welded or bolted to the vessel infrastructure to provide a permanent base for the Merlin
LT. The mounting plate should be installed aligned to the vessel centre line.
Predrilled, threaded holes provide locations to bolt the Merlin LT onto the mounting plate at different horizontal
angles:
•
0°: produces scan lines perpendicular to the vessel. This gives the best range from the vessel’s sailing line.
• 22.5°: rotation port and starboard. Produces horizontally offset scans which help when surveying features
perpendicular to the vessel’s sailing line – for example, the sides of buildings facing the vessel.
•
45°: rotation port and starboard. Produces horizontally offset scans which help when surveying features
perpendicular to the vessel’s sailing line – for example, the sides of buildings facing the vessel.
If the unit is moved horizontally, new lever arm values must be used. The heading calibration values must also be
changed in your navigation package.
Use M5 countersunk bolts to secure the mounting plate to the vessel.
Use M8 bolts to secure the Merlin LT base plate to the mounting plate.
For details on using the mounting plate, see section 4.4.
