Seiwa SW AP03 - Manual (Page 26)

MENU 3
COMPASS TYPE This allows a selection between a heading input from a fluxgate
compass (or slave) and a digital heading input via one of the NMEA
ports. There are two digital heading options: a magnetic heading
(HDG) or a true heading (HDT). If the true input is used, a T
symbol appears on the right of the working display and all
navigation headings are shown as true.
NMEA OUTPUT The NMEA heading output may be selected between HDG
(magnetic) and HDT (true). Some version may also show a SIM
option. This is for factory testing and is not used in an installed
pilot.
STALL ALARM ON The Drive Stall alarm is activated after a Cold Start, but this
option may be used to disable it, if necessary. We
recommend that it not be disabled for normal use.
REMOTE LOCK If the Remote Lock is switched on, the system will only respond to a
remote steering attachment when it is in PILOT.
TUNE MONITOR For technician use to check the operation of the automatic tuning.
STEER DRIVE This may be used to run the steering drive continuously for bleeding
purposes. Note that if the rudder transducer is not coupled, there is
a risk of driving the steering gear against the stops. Press the left
or right arrows to start and stop the drive.
COMPASS MONIT Used to measure fluxgate output voltages for diagnostics.

sounds and an alarm message appears on the display. To cancel an alarm, press the
STANDBY or PILOT key. If the system is in PILOT and this key is used to cancel an off-
course alarm, for example, the reference course is not changed.
