The relations between drive units, drive unit voltage, autopilot
computer, drive performance and interface to the steering gear
are shown in the tables below.
Refer to the connecting diagram for the different drive units on
page 74 onwards.
Installation instruction for the drive units are found in the
manual for the individual units.
The maximum drive current capability of the AC10, AC20 and
AC40 autopilot computers are different. Use the table below as
reference and observe the notes on next page.

Notes !
1. The AP25 system detects whether a reversible motor or a
solenoid is connected and outputs the correct drive signal
automatically.
2. The drive output of AC10 is sufficient for any type of 12 and
24V solenoids normally found on a recreational boat.
