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
