Configuring Engine and Tank Information

If you have a multi-engine or a multi-tank setup on your boat, specify which engine or tank is associated with each GFS 10.

tiP: The serial number of each GFS 10 is shown on the NMEA 2000 device configuration menu to help differentiate among multiple GFS 10 devices.

To configure tank and engine information for the GFS 10:

1. While viewing the NMEA 2000 device configuration menu, select the GFS 10 device you want to configure, and select Config.

2. Select from the following options:

•

Engine

Number—for a multi-engine installation, assign the selected GFS 10 to a specific engine.

•

Tank

Number—for a multi-tank installation, assign the selected GFS 10 to a specific tank.

•

Tank

Capacity—define the fuel capacity of the fuel tank that the selected GFS 10 is connected to.

Troubleshooting Fuel Gauge Type

When wired to a fuel gauge, the gauge type defaults to Auto Detect. If the fuel-level reading on your Garmin chartplotter or marine instrument

changes with the engine RPM, the GFS 10 could be detecting the wrong type of gauge.

Note: The fuel level changes with the motion of the boat. Perform this test when the boat is not moving.

To test the gauge-type setting:

1. When the boat is not moving, put the engine in neutral.

2. Use the throttle to increase the engine RPM. If the fuel-level reading changes with the engine RPM, change the gauge type.

To change the gauge-type setting:

1. While viewing the NMEA 2000 device configuration menu, select the GFS 10 device.

2. Select

Config

Type.

3. Choose

Troubleshooting the Fuel-Flow Reading

If the fuel-flow information received from the GFS 10 appears inaccurate, you can manually adjust the fuel-flow reading.

To adjust the fuel-flow reading:

1. While viewing the NMEA 2000 device configuration menu, select the GFS 10 device.

2. Select

Config

Flow

Adjustment.

3. Enter a positive or negative adjustment.

For example, when you set the Flow Adjustment to +10% , a flow reading of 20 gal./hr. (75 L/h) would change to a reading of 22 gal./hr.

(82.5 L/h), because 20 gal. × 110% = 22 gal. (75 L × 110% = 82.5 L).

Restoring Factory Default Settings

You can restore factory default settings to the GFS 10. You will lose all custom configuration and calibration settings when you restore factory

default settings.

To restore factory default settings:

1. While viewing the NMEA 2000 configuration menu, select the GFS 10 device.

2. Select

Config
