rudder limit, set uup issue

[Chuck - Raymarine - Moderator]

Eric,

Dockside calibration steps are performed to ensure that the autopilot senses the correct position of the rudder/outdrive/outboard and that the steering actuator is moving the rudder/outdrive/outboard in the correct direction in response to steering commands. Raymarine autopilots must not be commanded into Auto or Track modes when underway should the autopilot fail to pass dockside calibration. It is further recommended that Evolution autopilots not be commanded into Auto or Track modes until the autopilot has completed detecting magnetics (i.e. determining the sensed deviation in the location of the EV-1/EV-2 Sensor Core) and that the autopilot's heading has been verified/aligned.

Please click here to view a FAQ addressing how to test a rudder reference transducer. Should your rudder reference transducer's resistance measurements, then the rudder reference transducer should be replaced. When installing the rotary rudder reference transducer, care must be taken to center the rudder/outdrive/outboard prior to installing the rudder reference transducer. Additionally, the alignment tab (located on the opposite side of the rotary rudder reference transducer's arm) must be aligned with the alignment tab on the transducer's base (see diagram below) when securing the rudder reference transducer.



After ensuring the at the rudder movement portion of the Dockside Wizard has passed, then the wizard will attempt to verify that the steering actuator is moving the rudder/outdrive/outboard in the correct direction in response to steering commands. Should the rudder/outdrive/outboard move in the opposite direction in response to steering commands, then Please click here to view a FAQ addressing how to correct this behavior.

Finally, as Evolution autopilot are heavily dependent upon sensed speed, any speed through water sensor input should be assessed to determine whether it is functioning and accurate. If not, then the autopilot should be configured to use GPS SOG rather than Speed (through water) for sensed speed data.
