In G or GM type systems, check whether the external gyro input
is disabled.
5. Check if all the data output formats and IEC 61162/NMEA protocol
standard settings are set as required.
6. Check if the min./max. limits for the speed filter are well outside the
possible range of the vessel’s operating speed.
In high-speed craft, the max. speed value will have to be increased.
7. Check whether the parameters for the analogue rate of turn output,
the status in- and outputs and the rudder angle feedback inputs are
set, if required.
8. Go to the Manual Settings menu, ”Manual Settings Menu” on
9. Check if the operational parameters in the Manual Settings menu are
set to suitable values.
⇒
Wherever possible, automatic data input should be selected in pref-
erence of manual input.
10. Go to the User Setup menu, ”User Setup – Overview” on page 2-17.
11. Check if the current date and time are correctly entered in the User
Setup menu.
12. Control if the gyrocompass system with all connected equipment is
fully functional in operation.
⇒
Use the test mode in the ”Configuration Menu - Service Setup 1” to
check the heading output to serial and 6 step/° repeaters and the
analogue rate of turn output.
13. Check whether 105 VAC true RMS are set on the master PCB as
described in the ”Power-up Function Test” on page 5-9.
14. Check whether the gyrosphere current value in the Service Setup 2
(code 610), indicated at the CDU, matches with the true operating
value of the gyrosphere current measured (true RMS) at the 1
Ω
gyro
current test resistor (R103) on the master PCB, as described in the
”Power-up Function Test” on page 5-9 and ”Technical Pages –
Parameters” on page 8-25.
15. Check the alignment error correction applied as described under
”Alignment Error Correction” on page 7-9 and double check with the
exactly determined alignment error of the installing position.
16. Check whether the correction values for the magnetic compass
heading are correctly determined and entered into the magnetic
compass calibration table as described under ”Magnetic Compass
Calibration” on page 7-10, if required.
⇒
In case a step of the check procedure is not met as required, mend
the relevant installation condition to meet the requirements.
⇒
If all steps of the system configuration check procedure are met as
required, the NAVIGAT X MK 1 gyrocompass installation has been
successfully installed and tested.
