Owners manual

For the correct interconnection of the CT2 Motor Controller and the Autopilot refer to
Figures 2 through 4. A four-conductor, #24 AWG cable with shield will be satisfactory. The shield
of the cable should be terminated to the JOG COMMON terminal (or V-) in the Autopilot
distribution box and unterminated at the other end.
If Jog Levers are used to override the Autopilot, connect them to the terminals provided in the
Autopilot distribution box (see enclosed diagrams or the Autopilot manual).
If the drive system is a Rotary Drive or Linear Actuator, the clutch of the rotary drive, or the
lockup solenoid of the linear actuator, should be wired to the Switched Power and Jog Common
terminals in the Autopilot distribution box (refer to the interconnection diagram in your ComNav
Autopilot Installation and Operation Manual).
TESTING:
Close the breaker which provides power to the Type CT2 Motor Controller. It is normal to
hear a pop when the breaker is closed as the large capacitors in the CT2 Motor Controller charge
up.
To ensure correct rudder direction movement, place the Autopilot master select switch in the
POWER STEER position and press either the red or green ARROW key. The rudder should move
in the correct direction. If not, reverse M1 and M2 leads from the CT2 Controller to the motor.
Refer to the Autopilot Installation and Operation manual, and complete the Dockside Setup
procedure for the autopilot. After completing the Dockside Setup procedure, measure the hard-
over to hard-over time of the drive system.
To measure the maximum hard-over to hard-over time of the drive system, place the
Autopilot master select switch in the POWER STEER position and hold the red or green ARROW
key to make the rudder move fully from Port to Starboard or vice versa.
If the hard-over to hard-over time is less than 8 seconds, the rudder must be slowed down by
decreasing the pumpset displacement, or changing to a smaller pumpset / slower acting drive
unit.
If the hard-over to hard-over time is more than 16 seconds, the rudder must be sped up by
increasing the pumpset displacement or changing to larger pumpset / faster acting drive unit.
When the hard-over time is between 8 - 16 seconds, testing of the CT2 Motor Controller Drive Box
is complete.
