RAM MEMORY
ERROR
The portion of RAM memory used for temporary data
storage tested faulty.
The autopilot is not operable.
RUDDER
FOLLOWER ERROR
The autopilot has detected a problem with the rudder
follower.
Check for broken, disconnected or shorted wires, or a defective
rudder follower. The autopilot will switch to using the Ghost Rudder
program to control the rudder when the master select switch is in
the
PILOT
or
NAV
position. The digital and analog rudder angle
displays will not function in any mode. The
RF:ER
error message
will remain visible and the audible alarm will stay on until cleared.
Even though the alarm is cleared, the Rudder Follower "Failed
Point" on the display will remain visible.
RUDDER ERROR
The autopilot has failed to detect any movement by
the rudder in response to a command to move.
This error will only occur if the master select switch is in the
PILOT
or
NAV
position.
Place the master select switch in the
POWER STEER
position and
measure how long it takes after pressing the red or green
ARROW
key until the digital rudder angle reading begins to change,
particularly when the last rudder movement was in the other
direction.
If it takes longer than one second for the rudder to begin to move,
check for something which could cause a delay in the response of
the steering system such as air in the hydraulic steering or slack or
worn parts in the mechanical steering system.
Check for too low a setting of the Minimum Speed Potentiometer in
the CT1 Motor Drive Box (if one is used by the autopilot).
If the digital rudder angle display does not change, but the rudder is
definitely moving, check for a broken rudder follower linkage, or a
defective rudder follower.
If any of these alarm conditions occur, and cannot be easily rectified, return the autopilot
to an authorized service centre for servicing.
