    TI50 Thruster Interface The TI50 Thruster Interface is designed to provide a control signal for operating a thruster in an AP50 system by either on/off solenoids, analog ±10V control, or Danfoss PVEM valve. The thruster output signal is calculated in the TI50 based on operational mode and heading information received over RobNet from other system units.

  • Page 20: Ad50 Analog Drive

    AD50 Analog Drive The AD50 Analog Drive is designed to provide a control signal for operating an analog rudder in an AP50 system by either analog or proportional ±10V control, or Danfoss PVEM valve. The analog rudder output signal is calculated in the AD50 based on operational mode and heading information received over RobNet from other system units.

When AUTO mode is selected, the AP50 automatically selects the current vessel heading as the set heading and the rudder will move to midship position.

  • Page 30: Auto-Work Mode

    Simrad AP50 Autopilot Press the STBY button to regain manual steering STBY AUTO-WORK Mode The AUTO-WORK mode is an automatic steering mode to be used under operational conditions different from those normally found when a vessel is in transit on a pre-set course. Examples are trawling, towing, trolling on one engine, slow speed etc.

  • Page 31: Thruster Steering

    2.7 Thruster Steering If the vessel is equipped with a thruster, it can be connected to the AP50 system and the vessel can then be controlled by rudder, thruster, or both rudder and thruster. After connecting a thruster to the autopilot system (see the TI50 manual) the thruster type must be selected under the Installation Dockside menu (see page 126).

  • Page 33: Route Navigation

    Route Navigation When operating the AP50 in NAV mode to automatically steer through a route of waypoints, the AP50 will steer to the first waypoint in the route after you accept the first waypoint as the location to steer towards.

    STBY button. Note ! If the AP50 is connected to a navigation receiver that does not transmit a message with the bearing to the next waypoint, it will pick a Cross Track Error message and steer on Cross Track Error only. In that case you have to revert to AUTO mode at each waypoint and manually change the set course to equal the bearing to the next waypoint and then select NAV mode again.

  • Page 35: Selecting A Different Navigator

    Caution ! If an ECS is selected as a navigator, the course change verification is waved. This is done so the AP50 is capable of following a route in which the radius of the course change is pre-set in the chart system. Users navigating in this mode must use extra caution.

    Installation Figure 4-2 RF300S Rudder Feedback Unit Mounting (019356) Note ! Due to space limitations, it may be necessary to cut the length of the transmitter rod to move the RF300S closer to the rudderpost. Tighten the mounting screws for both the RF300S Rudder Feedback Unit and the transmitter rod ball joint.

    However, it can be mounted with the shaft pointing downwards for increased convenience. The deflection can then be inverted in the AP50 software or as illustrated in Figure 4-5 on page 77. An “upside-down” installation will make access to the unit more efficient as it can be opened without moving it from the mounting base.

  • Page 79: Electrical Connection

    Installation Electrical Connection Use a twisted-pair shielded cable, 0.5 mm (AWG20), between the breakout box and the J50 Junction Unit. The cable length is not critical but should be kept to a minimum. The cable should be connected to the junction unit according to Figure 4-5.

    Simrad AP50 Autopilot 4.8 RF14XU Rudder Feedback Unit Mechanical mounting Before installation check that the alignment mark on the mounting plate agrees with the mark on the shaft. Bring the rudder to Midships position. The feedback unit should be mounted on a plane surface and secured by bolts through the three holes in the mounting plate.
  • Page 83 Installation The feedback unit has an external ground terminal an must have a proper ground connection to the hull.
