Test Procedure For Sig.distributor; Speed Log Master Display In Jln-900 Speed Log - JRC JLN-900 Installation And Instruction Manual

Test procedure for Sig.Distributor

Refer to and note in protocol on page 12-11!
Note revisions and serial numbers of the Sig.Distributor and the three PCBs in the
protocol.
Connect power to the Sig.Distributor wait for completed start-up and then use the
NWW-82 Master Display to access the menu system in the Sig.Distributor.
Revisions of software and firmware can be inspected via the menu system (M8 and
M9). Note the revisions in the protocol.
Refer to the manual to access the Sig.Distributor menu system via the NWW-82
Master Display. Generally default settings are used. If any customer or installation
options, then set and note accordingly, e.g. for Docking Log function.
Actual speed and depth values from the speed log can be viewed on the start menu of
the Sig.Distributor. The next tests verify that the connections between the JLN-900
Speed Log speed log Sig.Processor and the Sig.Distributor are correct.
Set the SOG speed log in speed simulation, i.e. default values in menus:
T1 BTLONG= +12.00KN, T2 BTTRANS= +0.09KN and T3 DEPTH= 10.0 M.
Check that same values are displayed in the start menu of the Sig.Distributor.
Check that the NMEA-message contains same values and signs and corresponds with
the NMEA standard $VDVBW message as defined in Technical Document
Verify that all NWW-82 indicators and external users of Sig.Distributor information
receive the simulated speed and depth (NMEA, pulse and analogue users).
Restore the SOG to normal operation. If the depth below the hull is at least 2 metres,
the SOG shall lock to the depth and present zero or close to zero speed.
A similar test procedure can be done from STW by entering the T1.1 menu as above
and verify STW speed to appear on all displays and users.
Exit all Simulation modes and Menu mode and return to normal operation.
7. Speed Log Master Display in JLN-900 Speed
Log
Refer to and note in protocol on page 12-7!
A set of labels, intended to identify the Speed Log Master Display function, is
provided for all JLN-900 Speed Logs and normally found in a plastic bag
attached to the Sig.Processor unit.
Verify that these labels are applied accordingly to the dedicated NWW-82 Main
Display as connected to the Sig.Distributor for the Master Display function.
Refer to the manual for instructions.
