6 Startup and Commissioning of System
6.1 General
The VSS-V2 units have been fully tested in our test laboratory before
delivery. To ensure that the system operates properly after installation
and configuration, carry out the following procedures before using the
system.
6.2 Mechanical Inspection - Panels
● All equipment is well fastened in the console or wall.
● All cable and cable glands are well tightened and fastened.
6.3 Mechanical Inspection - Microphone Unit
The unit is installed according to procedures described in section 4.2.2.
L
Important!
The microphones shall be installed in such a way that they are
as far away from noise sources on the vessel as is practically
possible, where wind-induced noise from objects (such as wires )
and mechanical vibrations are reasonably reduced.
6.4 Cable Inspection
Make sure that all cables are connected according to section 4.7 Cable
Connection Diagram and check all terminals. Check that:
● All signal cables are min. 0.75 mm
2
approved ship cable of type
twisted-pair with outer braided copper shield
● All cable shields are connected to the ground terminals
● Power cable is 0.75 mm
2
and connected to terminal block K9 (+ to
terminal 1, - to terminal 2). The shield is grounded on terminal 3.
● Cable for microphone is arranged according to section
4.2.3 Microphone Cable Precautions
6.5 Start Up Master Panel
Set master panels to on. When the green status / self test LED is
steadily lit, use a horn or similar device that sends out harmonic
signals with a higher SPL than the background noise to activate each
microphone. The master panel shall activate the diode from the correct
direction. At the minimum, check all sides FWD, AFT, STB and PORT.
See section
7 Operating Procedures for all other functions.
6.6 Start Up Slave Panel(s)
Set slave panels to on. Use the same procedure as for the master
panel.
6.7 Ship’s Typhoon/Foghorn
Activate the ship’s typhoon/foghorn and check that the system is muted.
