CLUTCH VOLTAGE SELECTION
NOTE: The ACP1 Computer Unit does not have dip switches for clutch
voltage selection. The clutch output voltage is fixed at 12V and is
therefore only suitable for Size 1/12V Rams and pumps and 12V rotary
drives.
The ACP2 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 4 screws holding the Computer
PCB in the lid of the Computer Unit, carefully lift the PCB clear.
Set the switches as per the table below. The default setting is 9V,
switch 4 ON, suitable for Size 1/12V Rams and Size 2/12V Rams.
