Garmin GFS 10 Instructions D'installation page 5

Notes:
• Consult the owner's manual provided by your boat manufacturer to determine the ground, ignition, and level-sensor connections on your fuel gauge� Often, the ignition
connector is labeled "I" or "+", and the level-sensor connector is labeled "S�"
• If you do not have a fuel gauge, but you do have a fuel tank with a level sensor, connect the brown wire to the "+" terminal of the level sensor at the tank� DO NOT
install the fuse holder near the tank—extend the brown wire to the tank with 24 AWG wire� Complete this connection before completing any other wiring connections to
reduce the risk of a spark near the fuel tank� Leave the grey wire unconnected�
• If you are using NMEA 2000, be sure to leave the orange wire unconnected�
Multiple GFS 10 Devices
If your boat has more than one engine or fuel tank, you will need multiple GFS 10 devices� Each GFS 10 can function as one flow sensor and one level sensor� You
need one GFS 10 flow sensor for each engine, and one GFS 10 level sensor for each fuel gauge or for each fuel tank that has a level sensor� Depending on your
boat, you may use only the flow-sensing capabilities of additional GFS 10 devices�
Multiple engines
Flow Sensing
Multiple fuel tanks for one engine
Level Sensing Multiple tanks with one fuel gauge and a manual switch
Multiple fuel tanks with multiple gauges
Multiple fuel tanks with no fuel gauge
nOTE: When using multiple GFS 10 units on multiple engines, it is normal to read different fuel flow rates on each GFS 10 unit� Similar engines do not always consume
fuel at the same rate�
Step 4: Connecting the GFS 10 to Your Chartplotter
The GFS 10 transmits data to your chartplotter or Marine Instrument using either NMEA 2000 or Garmin CANet�
Connecting the GFS 10 through nMEa 2000
The GFS 10 is packaged with a NMEA 2000 T-connector� The GFS 10 has a built-in NMEA 2000 drop cable� Use these two components to connect the GFS 10
to your existing NMEA 2000 network� If you do not have an existing NMEA 2000 network, you will need to install a NMEA 2000 network on your boat� For more
information on NMEA 2000, visit www�garmin�com�
To connect the GFS 10 to your existing NMEA 2000 network:
1.
Determine an appropriate location to connect the GFS 10 to your
existing NMEA 2000 backbone�
2.
Disconnect one side of a NMEA 2000 T-connector from the backbone nearest to the location where you want to connect the GFS 10�
If you need to extend the NMEA 2000 backbone, connect an appropriate NMEA 2000 backbone extension cable (not included) to the T-connector you
disconnected�
3.
Connect the included T-connector for the GFS 10 to the NMEA 2000 backbone�
4.
Route the built-in drop cable on the GFS 10 to the bottom of the
T-connector you added to your NMEA 2000 network�
If the built-in drop cable is not long enough, you can add a drop cable extension up to 14 ft� (4 m)� If more cable is needed, add an extension to your NMEA 2000
backbone, based on the NMEA 2000 guidelines�
Connecting the GFS 10 through Garmin Canet
The GFS 10 is packaged with a Garmin CANet adapter that you can use to connect the GFS 10 to your existing Garmin CANet bus� If you do not have an existing
CANet bus, you will need to install a CANet bus on your boat with a Garmin CANet Kit (010-10742-00)� For more information on Garmin CANet, visit
com�
To connect the GFS 10 to your existing CANet bus:
1.
Determine the location on your CANet bus where you would like to connect the GFS 10�
2.
Wire the CANet adapter to your existing CANet bus using the diagram below to make the appropriate connections�
Follow the instructions included with the CANet Kit (010-10742-00) to determine whether a terminator is needed in the location where you install the GFS 10�
3.
Route the built-in drop cable on the GFS 10 to the CANet adapter, and complete the connection�
GFS 10 Fuel Sensor Installation Instructions

One GFS 10 per engine–install after the tank switch
One GFS 10 wired to the fuel gauge
One GFS 10 per tank–wired to each gauge–up to two tanks
One GFS 10 per tank–wired to the level sensor (if available)–up to two tanks
