all other functions operate normally. Cancel it by returning to
course or pressing the STANDBY or PILOT key.
HELM ALERT In PILOT mode, the helm alert operates in three stages. One minute
before the preset time (5, 10 or 15 sec.), the HELM ALERT
message flashes on the display without the beeper sounding. At
the preset time the message is on continuously and the internal
beeper sounds. One minute later, the external alarm sounds. The
alarm is cancelled and reset by the PILOT or STANDBY key.
DRIVE OVERLOAD The current drawn by the steering gear has exceeded the limits and
the drive has been turned off. See Chap. 4 for further information.
DRIVE STALLED If the steering drive is activated and the helm moves less than 1
degree in 2.5 seconds, the system is switched to STANDBY and
this alarm is set.
Either the rudder has travelled past the limits set during System
Setup or an electrical fault has developed in the Rudder
Transducer. The system switches to STANDBY.
COMPASS FAULT If a fluxgate compass has been selected, the magnetic field being
sensed by the compass is above or below preset limits. Further
information is given in Chap. 4.
NO HEADING DATA If a digital heading input has been selected, a valid heading sentence
is not being received.
OFF CENTRE This alarm is only used during the setup procedure and occurs
if the helm is not correctly centred for the last stage of the
setup.
SYSTEM FAULT
This alarm is generated by the Controller to indicate that no data is
being received from the Junction Box. This can indicate either a
fault in the Controller cable or a failure within the Junction Box.

procedure and are then adjusted automatically while under way.
