SmartPilot Series Commissioning Guide
CAUTION:
Do NOT connect the solenoid return cables to boat’s negative
ground, as this will bypass the current protection devices inside
the SmartPilot computer.
Selecting clutch voltage (S3 & S3G only)
You can use the S3 and S3G SmartPilot computers with other manufacturers’
drives that have either 12 V or 24 V clutches. If you do this, you may have to
reposition the clutch fuse.
Important:
All Raymarine 12 V and 24 V drive units with a clutch have a 12 V
clutch, so you do NOT need to re-position the clutch fuse.
If you are using another manufacturer’s drive, ascertain the operating voltage of
the
CLUTCH. Ensure the clutch fuse is set to the correct voltage, i.e. to the left for
a 12 V clutch, or right for a 24 V clutch. If necessary, select the appropriate clutch
voltage by re-positioning the clutch fuse.
It is important to appreciate that the fuse position does NOT depend on the
voltage used on your boat, but on the operating voltage of the CLUTCH.
