86 ST4000+ Wheel & Tiller Autopilots: Owner’s Handbook
6 Setting-up the ST4000+
6.1 Functional test
Switch on
1. When you have installed your ST4000+ autopilot system, switch
on the main power breaker.
2. If the control unit is active and the system operating, the control
unit will beep and display the pilot type (
4000 WHL or 4000 TILL).
CAUTION: Wheel drive systems
One second after power-on the wheel pilot will drive to starboard
for three seconds. This is to allow even wear on the drive belt.
3. After displaying the pilot type for two seconds, the control unit
will then display the
Standby screen.
Troubleshooting
• If the head does not beep, check the fuse/circuit breaker.
• If the display shows the
SEATALK FAIL alarm message, check the
SeaTalk connections.
Autopilot steering direction
The autopilot steering direction defines which way the autopilot
applies helm when you press a course change key or when the boat
goes off course.
Check the autopilot steering direction as follows:
1. Wheel Pilot: Engage the wheel drive clutch by rotating the clutch
lever clockwise so it engages fully onto the locating pip.
Tiller Pilot: Place the pushrod end over the tiller pin. If
necessary, use the
-1, +1, -10 or +10 keys to extend or retract the
pushrod.
