5.4 Initial System Configuration
To make the system fully functional, the configuration parameters need to be
set to the required values in the Service Setup 1. Additionally, the applicable
standard operational settings should be entered in the Manual Settings menu.
To configure the system:
1) Check that the wiring has been carried out completely. All devices con-
nected to data or signal in- and outputs should be operative.
2) Energize the system at the vessel's switch and fuse unit.
A startup message is displayed and the initial selftest is executed.
3) Go to the Service Setup 1 (code 600).
4) Select the required system type and heading reference selection settings.
5) In dual or triple gyro systems, assign the required compass ID.
6) Select the required data formats for all devices connected to the data in-
puts. In G-type systems, disable the magnetic heading input.
7) Select the required data output formats and the NMEA protocol standard.
8) If required, set the parameters for the analogue rate of turn output and for
the general alarm relay.
Warning Warning
When the compass is energized (24 VDC main and/or backup supply present),
the gyrosphere operating voltage of 100 VAC @ 337 Hz is present on the main
PCB, the gyrosphere supply lines and accross the gyrosphere contacts.
When operating the compass while the housing is open, do not touch the main
PCB, the connecting cables to the gyrosphere container or the base contact.
Note
If the initial system configuration is carried out before the installation of the gy-
rosphere, the system will raise a „gyro failure“ alarm at power-up.
The alarm may be safely acknowledged at this point to continue with the initial
configuration.
Note
Do not change the factory-set shaft correction angle in the Service Setup 1. The
alignment error correction may be set to an approximate value at this point.
The existing alignment error, however, must later be exactly determined and
corrected as described in .
