ComNav 1101 Autopilot4 - 20 INSTALLATION
Electrical Check List
This subsection explains how to verify that your Autopilot system
installation is complete and has been installed in a safe and secure
manner.
- Check the power source from the battery for correct polarity, wire
size, tightness of connections, fusing, and operation of the
battery power switch before connecting the power cables into the
power terminals on the Distribution Box. The Autopilot in a
minimal system nominally draws about 150 milliamperes of
current by itself without the Drive equipment.
- Check the connection from the compass to the SPU.
- Check the connections from the Rudder Follower.
- Check that when the rudder is moved
from full starboard to
full port, the Rudder Follower has full free movement and is
not being restricted in any way.
- Check the connection from the Control Head to the SPU.
- Check the connections to the drive equipment from the
Distribution Box.
- Check that the cables are neatly placed and secured.
- Check manually that the steering system is operating correctly.
- Ensure that all extraneous materials (wire strands, etc) have been
removed.
IMPORTANT
Before turning on the
power, check that the
cable from the
Distribution Box is
connected to the SPU
connector labeled
“Distribution Box”.
If this cable is connected
to the SPU connector
labeled “Control Head”,
damage to the SPU could
result.
