	clutch voltage selection

The h1000 pilot computer unit can output different clutch/solenoid voltages depending upon the size of rudder drive unit fitted. The clutch/solenoid valve is only required for rams or rotary drive units. This is achieved by setting dip-switches on the computer drive PCB. Access to the switches is obtained by removing the four screws holding the computer PCB into the lid of the computer unit and then carefully lifting the PCB clear.

Set the switches as per the table below. The default setting is 9V, switch 4 ON, which is suitable for Size 0, 1, and 2 12V rams.

Dip Switch	Clutch Voltage	Drive Size / Type
1	24V	24V Rotary
2	18V	Size 2 and 3, 24V Rams
3	12V	12V Rotary
4	9V	Size 0, 1 or 2 12V Rams
