Installation manual
Sensor installation
The OMC-116 must be mounted
on top
of a mast
(Ø 45 .. 60mm) with the included U bolts.
Make sure the sensor is free of obstacles.
Recommended sensor height is 10m. Wind speed should be
measured at 10m height however an obstacle free environment
is more important.
Bracket & U-bolt must make contact with metal of the mast to lead any static
discharge to ground.
If this is not possible due to coating etc. a proper earth lead
must be connected to 1 of the U-bolts.
The mast must be correctly earthed to regulations.
Cable connection
The shield of the cable(s) may not be laid to ground on the receiving (display /
signal conditioning) side of the cable
but must be connected on sensor side.
The junction box does have an extra (plugged) M20 hole in case separate cables are used
for signal and power.
Alignment
The sensor must be lined up to North (fixed applications) or for ship applications to the bow
of the vessel.
The OMC-116 has several markings indicating the North / Bow
direction of the sensor:
1.
Arrow on top
2.
Small arrow on sensor deck
3.
Drilling hole visible from below
4.
Front junction box
