4. INPUT/OUTPUT SIGNALS
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.
