5.7 GRAVITY SWITCH
In installations where two speed sensors or depth
transducers are fitted a gravity change over switch can be
fitted to automatically select the leeward sensor. A switch
on the outside of the unit over rides the automatic selection
if required, for example when calibrating the individual
speed sensors.
On a Hercules system it is not necessary to use a gravity
switch for a second speed sensor as two sensor inputs are
available using the Pulse 2 function.
5.8 AUDIBLE ALARM
The main processor contains a relay switch for an external
audible alarm.
Note
• The current drive capacity of any alarm connected to the
system must not exceed 0.5 Amps.
5.9 NMEA INTERFACE
Several methods are available for interfacing NMEA data to
the h2000 system:
The Main Processor has a NMEA input which can
accept data from GPS, Heading and/or Depth sources.
