Simrad AP26 and AP27 Autopilots
Rudder Test
Note ! If the boat uses power assisted steering, it is important that the engine or electric motor used to enable the power assist steering be turned on prior to this test.
Bring the rudder manually to midship position before starting the test.
Caution ! Stand CLEAR of the wheel and do not attempt to take manual control of the wheel during this test!
Activate the automatic rudder test by turning the course knob clockwise.
The autopilot will after a few seconds issue a series of PORT and STBD rudder commands and automatically verify correct rudder direction. It detects minimum power to drive the rudder, and reduces the rudder speed if it exceeds the maximum acceptable speed (8°/sec.) for autopilot operation.
The Rudder test is verified by the display showing ‘Motor OK’, ‘Solenoids OK’, or ‘Failed’. If ‘Failed’ is given, check for correct electrical connection.
The Motor Drive out (displayed in percentage) is the amount of maximum available power needed to achieve correct rudder speed on automatic steering (Maximum speed is used in NFU mode).
The screen also tells whether a clutch is installed or not.
If the Automatic rudder test fails, refer to ”Alarms” beginning on page 118.
