Introduction: CT2-40A Motor Controllers are designed to connect a ComNav Autopilot to a steering system using a permanent magnet, shunt field, or compound reversing D.C. Motor. CT2-40A Motor Controllers feature dynamic braking, current limiting and thermal protection of the MOSFET driving transistors while allowing full power acceleration and drive when needed. CT2 Motor Controllers can be used with 12, 24 and 32 VDC battery systems.
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).
TROUBLESHOOTING: • Check with a voltmeter that voltage is present between Terminals J1, V+ and J1, V- (the battery voltage). • If no voltage is present, check that there is power to the breaker panel, and that the breaker for the motor is turned on. Recheck the wiring from the breaker panel to the CT2 Drive Box. • If voltage is present, use an ohmmeter to check the 30 AMP Fuse (F1). Check the 1 AMP Fuse (F2) as well. If either is faulty, replace with the same size fuse.
• If the motor runs: 1. Check the outputs from the Autopilot for correct operation. The red and green output diagnostic LED's in the Autopilot distribution box should come on as described in the ComNav Autopilot Installation and Operation Manual. 2. If the diagnostic LED's do come on and the rudder still will not move, examine the wiring between the Autopilot and the CT2 Motor Controller again. Check for open or short circuits. Check for nails or staples which may have penetrated the cable. 3.
