Installation Guide for the fuel flow transducer

A small amount of fuel may be released when the fuel feed hose is disconnected.
Place container under the fuel feed hose or 3-way joint pipe with a shop cloth so that released fuel is caught in container or absorbed in cloth. Place fuel soaked cloth in an approved container.

Gasoline is extremely flammable and toxic. Always observe the following precautions when working around gasoline or servicing the fuel system.
● Disconnect battery cables except when battery power is required for servicing/inspection.
● Keep the working area well ventilated and away from open flame (such as gas heater) or sparks.
● Do not smoke or allow anyone else to smoke near the working areas.
Post a "NO SMOKING" sign.
● Keep a fully charged CO2 fire extinguisher readily available for use.
● Always use appropriate safety equipment and wear safety glasses when working around pressurized fuel system.
● To avoid potential fire hazards, do not allow fuel to spill on hot engine parts or on operating electrical components.
● Wipe up fuel spills immediately.

The fuel flow transducer should not be installed on the engine. Always install the Fuel Flow Transducer AFTER the primary filter. The Primary filter must be a good quality water separator type with a minimum filtration of 30 microns or better.
Damage due to insufficient filtration is not covered by warranty. If in doubt please consult your dealer for advice prior to installation.

Installation of the fuel flow transducer

The fuel flow transducer is designed for installation in Coast Guard approved flexible fuel line. It should not be installed on the engine. The transducer MUST be installed AFTER the main fuel filter.

It should be located well away from any area where it will be affected by excessive heat or vibration from the engine. It is preferable to mount the transducer in a vertical position.

To install, drain all the fuel from the flexible fuel line. Cut the fuel line and, using the fuel hose attaching clips provided, install the transducer so that the FUEL IN side of the transducer is connected to the fuel line from the fuel tank.

Wiring Connection

  • Keep electrical and transducer cables away from alternator or other noise generating electrical cables.

Operation

Tachometer

The tachometer is a digital instrument with the appearance of an analog instrument. The tachometer is preset at the factory for a 6 pulse input. The setting for the tachometer can be changed in the Set-Up menu (Set-Up Mode page 10).

A microprocessor controlled stepper motor moves the pointer to display engine revolutions per minute using a linear dial.

The Commander™ has three push buttons: “Mode”, “Up”, and “Down”.

The “Mode” button is used to change the function of the LCD display and to access sub menus and adjustable settings.

The “Up” and “Down” buttons are used to modify the settings.

In normal operation mode, pressing the “Mode” button quickly causes the display to cycle between the different instrument displays. Pressing and holding the “Mode” button causes the display to change to the “settings” sub menus (see Figure 3, page 9).

When the settings menus have been selected, pressing the “Mode” button quickly causes the display to cycle through the setting options. Within each setting selection, pressing the “Up and “Down” buttons causes the affected setting to change.

The microprocessor will automatically record the new settings as you adjust them.
When in a setting menu, pressing and holding the “Mode” button returns to the main function.

Lighting

In the normal operating mode the instrument lighting can be adjusted by pressing the “Up” and “Down” buttons.

The Tachometer and Fuel Level functions have several values that can be adjusted to match your installed equipment. These are changed in the Set-Up Mode. (See Figure 4, Table 1, and Table 2, page 14 & 15).

Use this option only if you have reason to believe that your settings are wrong. Setting an incorrect value in these menus can result in extremely inaccurate performance of the tachometer and fuel level sender.

Fuel Management Functions

Description
The Commander™ Tachometer/ Fuel Monitor/ Engine Hour meter combines the features of several instruments into one unit. The LCD displays the information for:

  1. Engine Hours - Displays the number of hours the engine has been run.

  2. Fuel Level - Displays fuel level in fuel tank (based on level sender) in percent.

  3. Fuel Flow - Displays current fuel usage in Gallons or Liters per hour.

  4. Fuel Used - Displays fuel used since last reset (trip fuel meter).

  5. Total Fuel Used - Displays total fuel used since last reset (total fuel meter).

  6. Fuel Remaining - Displays the fuel remaining since last set (based on fuel flow).

Engine Running Only Hour meter

The Engine Hours display shows the number of hours the engine has been operated (Hr). The reading is based on a signal being received at the tachometer input to indicate that the engine is running. Units are displayed as:

Fuel Level

The Fuel Level display shows the amount of fuel in the fuel tank in percent of full (PC).

The indication is based on the fuel level sender in the tank and operates similarly to a normal fuel gauge. There are no adjustments to this reading.

Fuel Flow

The Fuel Flow display shows current fuel consumption in gallons per hour (GH) or liters per hour (LH).

The fuel flow sensor can be calibrated if necessary using the Fuel Used “settings” menu (see Fuel Used description below).
The units displayed may be changed using the submenu.

Pressing and holding the “Mode” button causes the display to change to the “UNITS” submenu (see Figure 3, page 9).

Fuel Flow “UNITS” Menu

Pressing the “Up” and “Down” buttons will change the setting between GH and LH.

Gallons per Hour (GH)

Liters per Hour (LH)

Fuel Used

The Fuel Used display shows the amount of fuel used since the gauge was reset.
The display is based on the fuel flow system and therefore filling the fuel tank will not disturb the reading.

The Fuel Used display may be reset to zero and the Fuel Used and Fuel Flow system calibrated using the sub menus.

Pressing and holding the “Mode” button causes the display to change to the “settings” submenu (see Figure 3, page 9).

Fuel Used “Settings” Menu
There are two items in the Fuel Used “Settings” Menu; Reset and Fuel Calibration. Briefly pressing the “Mode” button cycles through the menu items.

The microprocessor will automatically record the new settings as you adjust them.

Reset

Pressing the “Up” and “Down” button resets the Fuel Used gauge to zero.

Calibration

If you know “exactly” how much fuel you have used since the Fuel Used gauge was reset you can adjust the amount and, therefore, the Fuel Flow sensor calibration in this “setting” menu.

Pressing the “Up” or “Down” buttons changes the “amount of fuel used” display.

When the displayed quantity matches the amount of fuel you know you have used, calibration is complete.

Total Fuel Used

The Total Fuel Used display shows the amount of fuel used since the Total Fuel Used gauge was reset.

This gauge is useful for keeping track of fuel usage over a longer period of time or distance than the Fuel Used gauge. The display is based on the fuel flow system and therefore filling the fuel tank will not disturb the reading. The Total Fuel Used gauge may be reset to zero using the submenu.

Pressing and holding the “Mode” button causes the display to change to the “settings” submenu (see Figure 3, page 9).

Total Fuel Used “Settings” Menu

There is one item in the Fuel Used “Settings” Menu; Reset.

Reset

Pressing the “Up” or “Down” button resets the Total Fuel Used gauge to zero.

Fuel Remaining

The Fuel Remaining display shows the amount of fuel remaining in G or L.

This display is based on your manually entered information (see Adjust Fuel Remaining below) and the accumulated Fuel Flow data since the gauge was adjusted. This information is not obtained from the fuel sender in the fuel tank and therefore is not affected by the boat position or angle as the fuel sender may be.

There is an alarm which may be set to warn of a low fuel condition. The amount of Fuel Remaining and the Fuel Remaining Alarm may be adjusted using the submenu.

Pressing and holding the “Mode” button causes the display to change to the “settings” submenu (see Figure 3, page 9).

Fuel Remaining “Settings” Menu

There are two items in the Fuel Remaining “Settings” Menu; Adjust Fuel Remaining and Fuel Remaining Alarm.

Briefly pressing the “Mode” button cycles through the menu items.

The microprocessor will automatically record the new settings as you adjust them.

Adjust Fuel Remaining

When you fill the fuel tank or add fuel, you make a reasonable (or “exact”) estimate of the amount of fuel you have. Using this menu item you can enter (adjust) the amount of fuel remaining to your known (or estimated) amount.

Pressing the “Up” or “Down” buttons will change the indicated Fuel Remaining.

Fuel Remaining Alarm

This alarm may be set to warn you when there is only a certain amount of fuel remaining according to the Fuel Flow usage calculation.

Pressing the “Up” or “Down” buttons will change the Fuel Remaining Alarm setting.

Suzuki® Warnings

Description
Suzuki Warning Monitor Function Is a system that monitors all critical engine functions including engine temperature, over-rev protection, oil pressure & check engine diagnostics.

This information is displayed on the digital LCD screen of your Commander Series Instruments.

Information about the wiring to the Suzuki® harness can be found at the end of this manual. (See Figure 5, HN0394, page 16.

Engine Temperature:
The displayed warning is “OVR TMP”.

Rev Limit:
A signal from the engine ECU causes this warning indicating an over rev limit has been reached.

The displayed warning is “REV LIM”.

Oil Pressure:
Four stroke engine: An oil pressure switch is used.

The warning will be displayed as “NO OIL”.

Check Engine:

If a check engine warning is displayed when the engine is running, the words “CHK ENG” will be indicated on the LCD screen. You must stop the engine to retrieve the “flash” code that designates which problem has occurred. You must return to engine idle speed and either pull the emergency stop switch to stop the engine (but leave the ignition key in the on position) or turn the key switch off to stop the engine, then turn it back on (do not restart the engine).

With the engine not running and the key in the ”ON” position, the words “CHKENG” will flash the current diagnostic codes(s). A diagnostic code of 2-4 will consist of 2 “CHK ENG” flashes with a pause and then 4 “CHK ENG” flashes with a slightly longer pause.

Operating Mode:
On power up (key on), a limited self-test is performed to inform the operator that the system is active. The test activates the audible alarm and all warning messages. During the self test, the
audible alarm sounds for 1/4 second.

At the same time, the unit begins displaying all of the warning messages. Each warning message is displayed for 1 second. When all four messages have been displayed, the self test is complete.
