5000 the 5000 is a modern high performance autopilot specifically developed for sailing and motor vessels of up to it is exceptionally easy to operate and its advanced micro-electronic control circuit gives outstanding steering performance. The 5000 is distinguished by its automatic course locking c...

System description the 5000 is a modular system that can be built up from a minimum number of units to match the individual requirements of a wide range of sailing and power vessels. The rudder drive system may be chosen from a range of rotary, linear and hydraulic drive units to best suit the vesse...

1.2 drive systems mechanical steering systems may be driven by either a rotary or linear drive unit. Some steering systems are fitted with an autopilot drive shaft, and in such cases the choice of a rotary drive system is straightforward. In general, if a drive shaft exists and lost motion does not ...

1.2.2 linear drive unit the output ram of the linear drive unit is driven by a declutchable re-circulating ball leadscrew which enables the drive unit to .Be permanently coupled to the rudder stock via a simple crank or tiller arm. The drive is automatically engaged by means of an internal friction ...

2.0 installation the 5ccc is easy install and prepare for sea trials. Sound installation however is vital if the system’s high standard of performance and reliability is to be achieved. The installation notes should be followed carefully and in cases where special advice may be needed you are encour...

2.2 drive system the following notes describe the installation of both the rotary and linear drive units. 2.2.1 rotary drive unit the rotary drive unit is coupled to the vessel’s steering mechanism by a simple chain drive. Most steering gear manufacturers supply special autopilot drive attachments a...

2.2.2 linear drive unit the linear drive unit couples directly to the rudder stock at the tiller arm length recommended in fig. 9. It is usually preferable to couple the linear drive unit to the rudder stock via an independent tiller arm offer a standard fitting). In certain cases, however, it may b...

5.2.2 displacement power vessels the rudder control setting is much less critical on this type of vessel and it is not normally necessary to change the setting for different engine speeds. As a general guide initial testing should be carried out at setting ‘4’ and reduced as much as possible ‘consis...
