[. . . ] The solenoid valve connectors can only accept cable up to 12 AWG. If larger cable is required, 18 inches of 12 AWG should be used to wire to the connectors. The Type CR Interface may also be connected to alternative constant running hydraulic pump providing: · the solenoid coils take less than 10 amps · the response time of the solenoid valve is less than 80 milliseconds · the operating voltage of the solenoid coils is the same as the course computer supply voltage. It is important to minimise the overall cable length between the pump and the vessels power distribution panel. 44 TYPE 100/300 Operation and Installation Handbook Plumbing If the autopilot operated hydraulic cylinder is independent of the manual steering system, a solenoid operated bypass valve (Z079 (12V), Z122 (24V)) should be fitted to allow the cylinder to backdrive when manual steering. The bypass valve should be connected to the `bypass' connector on the Type CR Interface Unit. The bypass valve should be mounted between the autopilot steering cylinder ports and, under normal circumstances, be de-energised to allow the cylinder to backdrive. When the autopilot is engaged, the valve is energised by the Type CR Interface to allow the autopilot steering cylinder to drive the rudder. Hydraulic cylinder Bypass valve Autopilot hydraulic drive Manual steering system Cable to course computer 'Bypass' connector D766-1 Note: The bypass valve voltage must be matched to the course computer supply voltage, i. e. 12V or 24V. If the steering cylinder is unbalanced (single ended), a pilot operated pressure relief valve must be connected (as shown) to enable excess oil to be returned to the reservoir when the cylinder ram is retracting. Chapter 2: Installation 45 Hydraulic Linear Actuator The hydraulic linear actuator, with built in solenoid operated bypass valve and load limiting system, is designed for use as a secondary autopilot steering cylinder. The system is supplied prefilled and preplumbed for ease of installation. 6 1 5 4 9 7 10 2 8 3 11 X Drive Type 2 Type 3 Dimension X 180mm (7. 1in) 267mm (10. 5in) D776-1 1 Reservoir 2 Pump 3 Cylinder 4 Tie-wrap 5 Clip 6 Reservoir hose 7 Pump hose A 8 Pump hose B 9 Cylinder hose 10 Cylinder ball joint 11 Quadrant Installation Caution: It is important to note that the hydraulic linear actuator can exert a thrust of upto 2700 Ibs - this is the equivalent weight of a large family saloon car. If there is any doubt about the strength of the existing tiller arm or quadrant the steering gear manufacturer must be consulted. Also, the mounting foot should be bolted to a substantial member and always over engineer to ensure reliability and maintenance of correct alignment. 46 TYPE 100/300 Operation and Installation Handbook When siting the actuator the following points should be noted: 1. The actuator mounting foot must be mounted to a horizontal surface. There is insufficient movement in the swivel joint for vertical mounting. View from above D1034-1 # View from above 90 D1035-1 2. The drive end must be at right angles to the hydraulic cylinder when the tiller is amidships. D1037-1 View from above Chapter 2: Installation 47 3. Accurate angular alignment between the hydraulic cylinder and the tiller arm plane of rotation is extremely important ­ under no circumstances should any misalignment exceed +/- 5 degrees. 5° Max. 5° Max. D1036-1 View from astern Caution: The push rod must not be shortened as it contains hydraulic fluid. The push rod ball end must be attached to the tiller arm at the radius specified on page 45. Use the supplied fixing bolt with its flange positioned between the ball end and the tiller arm. It is very important that this bolt is a tight fit in the tiller arm. Use Loctite 638 (or an equivalent) to secure the tiller bar bolt and lock the securing nut.

Position the reservoir (1) so that it is at least 150mm (6in. ) above the pump (2). The pump (2) should be sited above the cylinder (3). [. . . ] After setting the gain at planing speed no further manual adjustment should be required. Warning: When speed information is fed to the autopilot via the NMEA input always check the displayed speed is close to the actual boat speed before locking the autopilot onto a heading. Delays in data transmission could result in the 'pilot' applying too much rudder after a large change in vessel speed. · If no Speed input or NMEA is available manual adjustment should be carried out to the Rudder Gain setting via the Response keys adjusting as follows: 1.
