External alarm
The SmartPilot sounds all critical alarms from all controllers. On large or noisy
boats you can fit a Raymarine external alarm (part number: Z035, connected
through E85001 interface box) as a high volume audible repeater.
Wind vane (sail boats)
The SmartPilot computer can use wind angle information from a wind vane or
instrument to maintain a course relative to the wind. You can provide wind angle
information to the autopilot system by connecting it to a suitable SeaTalk or
NMEA instrument (providing wind angle and speed information)
Off switch (S2 and S3 only)
The SmartPilot computer has inputs so you can fit an off switch if required. By
closing a circuit, this switch will turn off the computer power supply.
Connect a suitable off switch to the
OFF SWITCH
inputs on the computer.
Other manufacturers’ drive units (S2 and S3 only)
If you are connecting another manufacturer’s drive unit, refer to the specifications
(see
page 65
) for information on the SmartPilot computer’s drive motor, drive
clutch and drive solenoid terminals. Connect the drive unit to these terminals as
necessary. For more information, contact the drive unit manufacturer.
Connecting spool valves (S2 and S3 only)
If the drive has spool valves, connect them to the motor and solenoid terminals on
the computer as shown below. The computer provides a negative ground for the
spool valves even when it is switched off.
