The Pendulum feature

The pendulum feature is intended for pendulum ferries where it is required to turn the
heading 180° when the vessel is going backwards. The feature can be included in systems
equipped with SD80 or AD80 boards.
The pendulum feature is activated by using an external switch. When the contact is closed,
the heading from the main compass and the monitor compass will change 180°. The
heading is changed before heading data enters the CAN bus network, and all devices on the
bus will pick up the modified heading.
Ú Note:
The system must be configured for the pendulum feature as described in the
separate installation manual.

Turning the system ON and OFF

Turning ON
Press the standby/brilliance key to turn the system ON.
The system will be ON as long as power is connected.
Switch the system to sleep mode
Press and hold the Standby/Brilliance key on an active control unit to switch the system to
sleep mode.
During the shut-down procedure the system will automatically go to Standby mode before it
is turned off.
Ú Note:
The Standby/Brilliance key will remain lit on units that are in sleep mode. To stop
the system from drawing current a separate breaker should be installed.

Taking command

You can take command from any control unit and/or remote by pressing the Command key.
In an open system (no command transfer restrictions) you will get immediate control from
the control unit requesting command. A steering handle without a Command key will get
control when the lever is operated.
In a multi-station system with active lock function, the command request must be confirmed
on the active control unit.
Active/passive units
In a system including more than one control unit and/or remote units, only one unit can be
in control at a time. All other units will be passive.
A passive unit is indicated with a passive icon in the mode status field.
On a passive/locked unit illumination can be adjusted, alert sound can be locally silenced,
and the Command key can be used for requesting command. All other functions are
unavailable.
