Issue 1.0 16/12/99 1 INTRODUCTION TO THE WP10 & WP30 WHEELPILOT The WP10 and WP30 Wheelpilots offer the benefits of high performance, low power consumption and quiet operation together with weatherproof protection and user friendly operation. They are entirely self-contained, all components - drive, compass and control pad are housed in a single unit with no separate compass to fit.

Issue 1.0 16/12/99 CALIBRATING THE WP10 AND WP30 Excerpts from the WP10 operation manual (also applies to the WP30 model). Configuration 3.1 Scaling Before using the Wheelpilot, it is necessary to pro- TACK TACK gram in the steering sensitivity, which is related to the number of turns that the wheel makes between end stops.

Issue 1.0 16/12/99 Drive Ring Assembly. Refer to drawing No. E03046 and fit the 2 Spoke Splines E02968:BK to the outside of the Front Guide Ring E02967 ensuring that the peg on the spoke spline locates into the outer hole, in the drive ring. Add a small quantity of Loctite 270 Green 260025 to the end of the thread of the screw protruding through into the front drive ring and fully tighten the M4 Half Nut 200147.

Issue 1.0 16/12/99 Clutch Plate Assembly. Locate the PTFE Clutch Shim E03040 and, ensuring that it is orientated correctly onto the cross pin, pass it over the gearbox output shaft so that it lays flat against the drive ring. Place Clutch Plate Assembly E03047 onto the clutch shim secure a Clutch Shoe E03041 to the plate assembly through the clutch shim and gearbox ring and secure with an M4 X 12 Csk Screw 200249, M4 1/2 Nut 200251 and a small quantity of Green Loctite 270 - 260025.

Issue 1.0 16/12/99 CIRCUIT DESCRIPTIONS 5.1 Wheelpilot WP10 PCB Assembly Introduction. The PCB Assembly is a generic item which can be used for Wheelpilots WP10 and WP30 and for Tillerpilots TP10, TP20 and TP30. The differ- ent versions are created by applying different components to the common PCB. The circuit diagram for the WP10 PCB is given in Drawing No.

Issue 1.0 16/12/99 Fluxgate (Compass). Two anti-phase signals are provided from microprocessor Ports P1.7 and P1.6. These signals are buffered by TR15 and TR16 to provide a high- er current drive to the excitation coil of the fluxgate. A reference voltage level of +2 volts is provided by R46 and R53 decoupled by C53.
Issue 1.0 16/12/99 5.2 Wheelpilot WP30 PCB Assembly Introduction. The PCB Assembly is a generic item which can be used for Wheelpilots WP10 and WP30 and for Tillerpilots TP10, TP20 and TP30. The differ- ent versions are created by applying different components to the common PCB. The circuit diagram for the TP20 / 30 and WP30 PCB is given in Drawing No.

Issue 1.0 16/12/99 Non-Volatile Memory (NVM). Integrated Circuit IC3 provides 1Kbit of E memory for the retention of important data after power down. Fluxgate (Compass). Two anti-phase signals are provided from microprocessor Ports P1.7 and P1.6. These signals are buffered by TR15 and TR16 to provide a high- er current drive to the excitation coil of the fluxgate.
Issue 1.0 16/12/99 5.3 Hall Effect PCB. Introduction. The Hall Effect PCB is a generic item which can be used for both Tillerpilots TP10, TP20 and TP30 and Wheelpilots WP10 and WP30. For Tillerpilots, the Hall Effect devices are mounted vertically into the PCB and horizontally for Wheelpilots.
Issue 1.0 16/12/99 PROGRAMMING AND CONFIGURATION For further details of normal operation please refer to the appropriate user manual - WP10 or WP30. Configuration 3.1 Scaling Before using the Wheelpilot, it is necessary to pro- TACK TACK gram in the steering sensitivity, which is related to the number of turns that the wheel makes between end stops.
