Step 9
Off switch
The course computer has inputs so you can fit an off switch if
required. By closing a circuit, this switch will turn off the course
computer power supply.
Connect a suitable off switch to the OFF SWITCH inputs on the course
computer.
Connecting an off switch
Other manufacturers’ drive units
If you are connecting another manufacturer’s drive unit, refer to the
specifications (on page45) for information on the course computer’s
drive motor, drive clutch and drive solenoid terminals. Connect the
drive unit to these terminals as necessary.
Connecting spool valves
If the drive has spool valves, connect them to the motor and solenoid
terminals on the course computer as shown below. The course
computer provides a negative ground for the spool valves even when
it is switched off.
CAUTION:
Do NOT connect the solenoid return cables to boat’s negative
ground, as this will bypass the current protection devices inside
the course computer.
Í For more information, contact the drive unit manufacturer.
