3.2 Preparation
General position:
!
Refer to the EMC installation guidelines.
!
Make sure the drive will be accessible for future servicing.
!
Mamba drives can be installed in any orientation directly onto the mounting flange on the bevel head or
reduction gearbox.
Environment:
!
The drive should be mounted in a dry location, clear of any bilge water.
!
Potentiometer (if installed) is not waterproof
Constellation & Bavaria drive structural strength:
!
This drive produces a considerable amount of force, so you must mount it on a solid structure
(i.e. a substantial frame member) in the boat. In some cases you may need to build a special frame to mount
the drive unit.
!
To prevent excess noise and vibration, do not attach this drive to any structures that support cabins.
Mamba drive Structural strength:
The Mamba drive is designed for mounting directly onto a bevel head or reduction gearbox in the steering sys-
tem, structural mounting instructions will apply chiefly to the gearbox that the autopilot is mounted to.
Cobra drive Structural strength:
The Cobra drive retrofits directly into the Integra Pedestal.
3.3 Optional rudder reference unit setup
!
Before installation of the autopilot, ensure the potentiometer used for rudder referencing is set to the middle
point of its total range (5 turns from either stop).
!
To do this, align the white marks on each pulley with the corresponding marks on the bracket/faceplate.
Be aware that the potentiometer will only turn 5 rotations in either direction from its centre point. If any
resistance is felt from the potentiometer do not apply force. Turn the sprocket in the opposite direction until
the white markings are aligned.
!
When both sets of markings are aligned the potentiometer should be at its mid point and ready for
installation. Note the markings will only line up at the mid point of the potentiometers range.
