4. INPUT/OUTPUT SIGNALS
4-4
Thrusters
•
One bow and one stern thruster with analog interface.
•
2-kohm potentiometers installed in all thrusters.
•
Reference voltage to potentiometers (+/-12v) supplied from the ECDIS.
•
Each analog input is associated with a status signal (closed contact) which indicates the
availability of the analog signal.
Rudder
•
One or two rudder indicators
•
Rudder indicators have the following sources:
•
Both actual and order can be received from a track pilot with serial data.
•
Actual can be received from analog interface and order can be received from a track
pilot in serial data.
•
Both actual and order can be received from analog interface.
•
Or alternatively port and starboard rudder feedback can be received from analog
interface.
•
Both actual and other can be received from IEC 61162-1 ($xxRSA).
•
Analog interface for rudder has following specification.
•
2-kohm potentiometers installed in the steering gear system.
•
Reference voltage to potentiometers (+/-12v) supplied from the ECDIS.
•
Typically the same rudder feed back unit can be used also for track Pilot system. (A
dual-potentiometer in the feed back unit is then required)
•
Each analog input is associated with a status signal (closed contact) which indicates
the availability of the analog signal.
Engine start air pressure
•
One engine start air pressure analog interface.
•
2-kohm potentiometers installed in engine start air pressure.
•
Reference voltage to potentiometer (+/-12v) supplied from the ECDIS.
•
Analog input is associated with a status signal (closed contact) which indicates the
availability of the analog signal.
