Important

It is the owner’s sole responsibility to install and use the instrument and its sensor(s) in a manner that will not cause accidents, personal injury or property damage. The user of this product is solely responsible for observing safe boating practices.

Fuel type: Navman petrol flow sensors (plastic) and FUEL 3100 instruments have been specifically developed for use in marine applications with petrol (gasoline) inboard and outboard engines and are not warranted for any other type of application. These sensors and instruments must NOT be used with petrol EFI engines with a return line to the tank or with diesel engines.

Navman diesel flow sensors (metal) and DIESEL 3200 instruments have been specifically developed for use in marine applications with diesel engines and are not warranted for any other type of application. These sensors and instruments must NOT be used with petrol (gasoline) engines.

Fuel formulation: Every effort has been made by the manufacturer to ensure that the materials used in the Navman fuel flow sensor(s) will operate reliably with different fuel mixtures. The manufacturer or its distributors can not be held responsible for fuel formulation or any affect this may have on the performance and durability of the fuel flow sensor(s).

Back pressure: A fuel flow sensor will create additional back pressure in a fuel system:

• In a petrol system (FUEL 3100): 1/2" of mercury at 19.8 US gallons /hour (75 litres/ hour) and 1" of mercury at 39.5 US gallons per hour (150 litres/ hour).

• In a diesel system (DIESEL 3200): 0.3" of mercury at 25 US gallons /hour (100 litres/ hour) and

1.5" of mercury at 80 US gallons per hour (300 litres/hour).

It is the owners responsibility to ensure that fitting the fuel flow sensor(s) does not cause fuel starvation which may lead to poor engine performance.

Fuel Computer: Fuel economy can alter drastically depending on the boat loading and sea conditions. The fuel computer should not be the sole source of information concerning available fuel onboard and the electronic information should be supplemented by visual or other checks of the fuel load. This is necessary due to possible operator induced errors such as forgetting to reset the fuel used when filling the tank, running the engine with the fuel computer not switched on or other operator controlled actions that may render the device inaccurate. Always ensure that adequate fuel is carried onboard for the intended trip plus a reserve to allow for unforeseen circumstances.

Specific requirements: Your boat’s fuel installation boat might be subject to specific requirements (such as USCG, NMMA and ABYC guidelines or local laws), particularly if the boat is licensed, surveyed, charted or inspected. It is the owner’s sole responsibility to install and use the instrument and its sensor(s) in compliance with these requirements.

NAVMAN NZ LIMITED DISCLAIMS ALL LIABILITY FOR ANY USE OF THIS PRODUCT IN A WAY THAT MAY CAUSE ACCIDENTS, DAMAGE OR THAT MAY VIOLATE THE LAW.

Governing Language: This statement, any instruction manuals, user guides and other information relating to the product (Documentation) may be translated to, or has been translated from, another language (Translation).

1 Introduction

This manual describ es two different Navman marine fuel instruments:

• The FUEL 3100, which is installed with the separate petrol/ gasoline flow sensor kit, and measures petrol consumption.

• The DIESEL 3200, which is installed with the separate diesel flow sensor kit, and measures diesel consumption.

This manual describ es how to install, set up and operate the instruments. For more information, refer to the separate Flo w Sensor Installation Manual (for the FUEL 3100 and petrol systems) and Diesel Fl ow Sensor Installation a nd Operatio n Manual (for the DIESEL 3200 and diesel systems); this manual has extensive information on understanding and optimising your diesel boat’s performance.

The FUEL 3100 or DIESEL 3200 measures and displays the fuel flow in real time for a single or twin engine boat. It can calculate and display the amount of fuel used, the amount of fuel remaining and the fuel flow rate.

If an optional speed sensor or speed instrument is connected, the unit can also

show the fuel economy, boat speed and the trip log and total logs.

Knowing the fuel economy can help determine the optimum throttle settings and maximize fuel savings. With twin engine boats, comparison between the flow rates of each engine can be used to achieve maximum synchronisation.

It is essential to update the fuel readings in the FUEL 3100 or DIESEL 3200 after a partial or full refill, or af ter manually removing fuel, to maintain accurate readings (see section 5).

The FUEL 3100 and DIESEL 3200 are par t of the Navman family of instruments for boats, which includes instruments for speed, depth, wind and repeaters. These instruments can be connected together, using NavBus or NMEA , to form an integrated data system for a boat.

Information in this manual applies to both the FUEL 3100 and the DIESEL 3200 unless noted. It is vital to read this document and the Navman instrument’s installation and operation manual before installing or using this kit.

1-2 How the flow sensors work

Petrol flow sensor (FUEL 3100): The petrol flow sensor is fitted in the fuel line between the fuel tank and the engine. A small turbine inside the fuel f low sensor measures the rate of the fuel flow into the engine. This information is relayed through the fuel flow sensor cable and shown electronically on the display unit.

Diesel flow sensor (DIESEL 3200): A diesel sensor is a positive displacement flowmeter, with one moving internal part, made of low

1-3 Cleaning and maintenance

Clean the display unit and any plastic sensor with a damp cloth or mild detergent. Avoid abrasive cleaners, petrol or other solvents.

1-4 Calibr ation

FUEL 3100: It is essential to calibrate the fuel flow sensors af ter installation and again af ter the first 100 engine hours to allow moving parts to wear in (see section 3-4).

3-4 Fuel calibration (CAL.F)

To calibrate a fuel ﬂow sensor, select CAL.F in the FUEL menu. Calibrate the sensors if you are doubtful of their performance.

FUEL 3100: It is essential to calibrate the fuel ﬂow sensors af ter installation and again af ter the ﬁrst 100 engine hours to allow moving parts to wear in.

DIESEL 3200: The sensors are factory calibrated and are highly accurate. They can be calibrated but this should not be necessary.

Calibrating a fuel ﬂow sensor requires accurate measurement of the fuel consumption. This is best done using a small portable tank. At least 4 gallons (15 litres) of fuel should be used to ensure an accurate calibration. The more fuel used, the more accurate the calibration.

Twin engine boats require both engines to be calibrated. Do these together with t wo portable tanks, or at diﬀerent times using one portable tank.

To calibrate an engine’s fuel ﬂow sensor: 1 Connect the portable tank to the

engine through the fuel ﬂow sensor.

2 Reset USED:

i Press one or more times

until USED is displayed.

ii If your boat has twin tanks,

press ENT one or more times to display PORT or STBD.

iii Hold ENT and together until

the reading resets to zero.

3 Run the engine at normal cruising

speed until a known amount of fuel, at least 15 litres (4 gallons), has been used per engine.

4 Select the FUEL setup menu, then

select CAL.F; if your boat has twin engines, select the PORT or STBD engine to be calibrated (see section 3-1).

5 If the value of CAL.F does not match

the known amount of fuel used, press ENT, then press or and change CAL.F until it does match. Then press ENT to save the correct value (otherwise press ESC to ignore the calibration).

3-5 Fuel flow damping (dAmP.F)

Waves and rocking of the boat cause the fuel ﬂow to ﬂuctuate slightly. To give a stable reading, the instrument calculates ﬂow by taking several measureme nts over a period of time and averaging them. This is called damping.

Set d Am P.F to between 1 to 99 seconds. Small values will give more accurate readings but will show ﬂuctuations. Large values will give more stable readings, but will ignore some true ﬂuctuations.

3-6 Speed input (InPUt)

Select the optional speed input: No : No speed input is available. GPS: Use GPS speed received via

NMEA. This is speed over ground.

SEn : The optional paddlewheel

sensor connected directly to the unit, or through the Navbus system. This is speed through water.

Note:

A speed input is required to disp lay L OG , TO TA L LOG, RA N G E and SPE ED (see

section 2-5). Speed over ground and speed through water

can give diﬀerent values for some displayed data (see appendix C).

3-7 Speed damping (dAmP.S)

(Only available if an optional paddlewheel sensor is connected to the unit and InPUt = SEn .) Waves and rocking of the boat cause the speed to ﬂuctuate slightly. To give a stable reading, the instrument calculates speed by taking several measurements over a period of time and averaging them. This is called damping.

Set d Am P.S to 1 (6 sec), 2 (12 sec), 3 (18 sec), 4 (24 sec) or 5 (30 sec). Small values will give more accurate readings but will show ﬂuctuations. Large values will give more stable readings, but will ignore some true ﬂuctuations.

(CAL.S )

(Only available if an optional paddlewheel sensor is connecte d to the unit and InPUt = SEn.) Select CA L.S to calibrate the paddlewheel speed sensor using boat speed.

You need an accurate way of knowing boat speed, such as another boat with a calibrated paddlewheel sensor or a GPS receiver.

For accurate calibration:

• The spee d from another paddlewheel sensor should be between 5 and 20 knots.

• Conditions should be calm, with little current (best at high or low tide).

To calibrate: 1 Travel at a constant, known speed. 2 Select the SPEED setup menu, then select

CAL.S, the boat speed.

3 If the value of CAL.S does not match the

known boat speed, press ENT then or and change the value until it does match. Then press ENT to save the correct value (otherwise press ESC to exit).

Note:

After you press ENT, it does not matter if the boat’s speed changes.

4-2 The display unit

1 Choose a location for the display unit that:

• is easily seen and protected from damage

• is at least 100 mm (4") from a compass and at least 500 mm (19.5") from a radio or radar antenna

• is away from engines, f luorescent lights, power inver ters and radio or radar transmit ters

• is accessible from the back; a minimum clearance of 50 mm (2") is required at the back (see mounting diagram)

• protects the back of the unit from moisture and water.

2 The unit must be mounted on a flat panel

less than 20 mm (0.75") thick . Stick the mounting template in place. Drill a 50 mm (2") fixing hole through the centre hole in the template. Note that the template allows space around the display unit for the protective cover.

3 Remove the fixing nut from the back of

the display unit. Insert the stud at the back of the display unit through the mounting hole. Hand tighten the fixing nut.

4-3 The fuel f low sensor(s)

Install the fuel flow sensor(s) following the instruc tions in the manual supplied with the petrol fuel or diesel flow sensor(s). Note the warning about fuel types in appendix B.

FUEL 3100: Plug the sensor cable into the FUEL 3100 cable with a white connector and do up the locking collar. For a twin engine or twin tank boat, follow the instruc tions in the Fuel Sensor Instal lation Manual.

DIESEL 3200: Connect the white sensor cable to the DIESEL 3200. For a twin engine installation install the white T connector and then connect the sensor cables to this.

4-4 The speed sensor (optional)

If required, install the optional paddlewheel speed sensor following the instructions in the manual supplied with the sensor. Plug the sensor cable into the FUEL 3100 cable with a blue connector and do up the locking collar.

If a NavBus or NMEA speed source is used, connect it to the power/data cable (see nex t page).

Warnings

1. The display unit is waterproof from the front. Protect the rear from water, otherwise water might enter the breathing hole and damage the display unit. The warranty does not cover damage caused by moisture or water entering the back of the display unit.

2. Ensure that any holes cut for the installation will not weaken the boat’s structure. If in doubt, consult a qualif ied boat builder.

Notes for both FUEL 3100 and DIESEL 3200:

Use a Navman junction box or any simple wire to wire connector system to wire the power/data cable. Tape or cover any unused wires or connectors to protect them from water and keep them from shorting together. The unit requires between 9 and 30 V DC power. To allow the engine hours counter to function properly the unit should be powered only when the engine’s igniton switch is turned on. With twin engines the unit ideally needs to work when either one or both engines are running. If acceptable power

not be powered from both ignition systems simultaneously.

If a Navman connector box is not used a 1 A fuse must be fitted in the power supply (+ ) line.

The instrument’s alarm output is switched to ground to sound the alarm, 30 V DC and 250 mA maximum. If the external alarms require more than 250 mA DC total, fit a relay.

FUEL 3100 / DIESEL 3200 Installation and Ope ration Manual

4-6 Systems of severa l instruments

Several Navman instruments can be connected together to share data, either by using NavBus or NMEA.

NavBus

NavBus is a Navman proprietary system that is high speed and allows a wide range of data to be shared by the instruments.

When instruments are connec ted by NavBus:

• Data from a sensor connected to one instrument is available to all instrument s.

• If the units, alarms or calibration are changed in one instrument, then the values will automatically change in all instruments of the same t ype.

• Each instrument can be assigned to a group of instruments by setting a group number between 0 and 4. Then, if the back light is changed in an instrument in groups 1, 2, 3 or 4, it will automatically change in all the other instruments in that group.

A typical NavBus system

Group 1

However, changing the backlight setting in an instrument in group 0 will not af fect any other instrument.

To assign the FUEL 3100 or DIESEL 3200 to

a group, set GrouP in the LAmP menu (see sec tion 3-3).

• If an alarm sounds, mute it by clearing the alarm on any instrument which can display that alarm.

• NavBus junction boxes simplify wiring.

For more information, refer to the NavBus

Installatio n and Operation Manu al.

NMEA

NMEA is an industry standard for marine instrument connec tions. The FUEL 3100 and DIESEL 3200 :

• Can read speed data (RMC) from a compatible NMEA GPS instrument (see section 3-6)

• Transmit PTTKV, VHW, XDR, VLW .

4-7 Testing the inst allation

To check out the installation: 1 Power on the boat and any other

instruments. Check the instruments work

properly. 2 Enter the setup data (see section 3). Set d UAL, motor , and InPUt first, then

enter the rest of the setup data. For boats with t win tanks or twin engines,

remember to enter port and starboard data

separately where required. 3 Fill the fuel tank (s) and set the fuel in the

tank(s) in the FUEL 3100 or DIESEL 3200 (see

section 5). 4 On boats with twin engines, check the

installation of the port and starboard fuel

sensors:

• DIESEL 3200: Star t the port engine. Check

the LED lights under the sensors are

blinking. This indicates the sensors are

operating correc tly. Confirm the fuel flow is

being displayed as port engine fuel usage

4-8 Resetting to factor y defaults

To reset to factory defaults: 1 Turn the power off.

5 When you add or remove fuel

When you add or remove fuel from a tank, you must enter into the FUEL 3100 or DIESEL 3200 how much fuel you have added or removed. Otherwise REMAINING, RA NGE and the low fuel alarm will be meaningless. Twin tanks connected by an open balance pipe should be trated as a single fuel tank.

When you add or remove fuel from a tank:

a When you fill a tank

1 Fill the tank. 2 Press until REMAINING is displayed. 3 If the boat has twin tanks, press ENT until

the display shows the name of the tank you

have filled, PORT or STBD. 4 Press and together. 5 If the boat has twin tanks and you are filling

the other tank as well, repeat the ab ove

steps.

NAVMA N

on the instrument. (If it is being displayed as starboard engine fuel usage, swap over the fuel flow sensor connectors on the ‘T’ connector.) Repeat the check with starboard engine.

• FUEL 3100: Star t the port engine. Confirm the fuel f low is being displayed as port engine fuel usage on the instrument. If it is being displayed as starboard engine fuel usage, reconfigure the set tings (see section 3-3).

5 FUEL 3100 only: Calibrate the fuel sensor(s)

(see sec tion 3-4).

6 If a paddlewheel speed sensor is

connected, calibrate it (see sections 3-8 and 3-9).

7 Take the boat for a trial run and check the

unit is displaying the correct data.

FUEL 3100: Recalibrate the FUEL 3100’s fuel sensor(s) after the first 100 engine hours (see section 3-4).

2 Hold ENT + while turning on the power

and for at least five seconds af ter.

Note:

It is often very difficult to refill underfloor fuel tanks to the same level twice, due to air pockets. Because of this, owners of boats with underfloor fuel tanks should:

• Ensure the boat is trimmed to sit at the same angle in the water each time procedure a above is followed.

• Mostly use procedure b below when filling the tank, but use procedure a above about every tenth fill.

b When you fill or part fill a tank

1 Before adding or removing fuel, press ESC

and ENT together, then press until the FUEL setup menu is displayed.

2 Press ENT, then press or until the

FUEL data is displayed.

FUEL 3100 / DIESEL 3200 Installation and Ope ration Manual

3 If the boat has twin tanks, press ENT. Then

press until the display shows the name of the tank to be filled, PORT or STBD.

4 Write down the number displayed, FUEL,

which is the amount of fuel now in the tank.

5 Add fuel to the tank , writing down how

much you add.

6 Add together the two figures you have

written down, to calculate the amount of fuel now in the tank. Press ENT. Then press or hold to change FU EL to the amount of fuel now in the tank.

7 Press ENT, then press ESC to return to the

main display.

8 If the boat has twin tanks and you are

adding fuel to the other tank as well, repeat the above steps.

6 Troubleshooting

This troubleshooting guide assumes that this manual has been read and understood.

It is possible in many cases to solve difficulties without having to send the unit back to the manufac turer for repair. Please follow this troubleshooting section before contacting the nearest Navman dealer.

There are no user ser viceable parts. Specialized methods and testing equipment are required to ensure that the unit is reassembled correctly and is waterproof. Repairs to the unit must only be carried out by a ser vice centre approved by Navman NZ Limited. Users who ser vice the unit themselves will void the warranty.

More information can be found on our website: www.navman.com

1 Instrument will not turn on:

a Power/data cable is damaged or

disconnected. Perform a visual check.

b Fuse is blown or circuit breaker has tripped.

Replace the fuse or reset the circuit breaker.

c Battery voltage is outside the range 9 to

30 V DC. Check the battery voltage using a multimeter.

2 The word SIM flashes at bot tom left

corner o f screen, values displayed are unexpected :

a The instrument is in simulation mode (see

section 2-9).

FUEL 3100 / DIESEL 3200 Installation and Ope ration Manual

Note:

If you follow procedure b above ever y time you add fuel, then a small error will accumulate, because it is hard to measure exac tly how much fuel you add. To avoid this, about every ten tankfulls of fuel, fill the tank and follow procedure a.

c When you remove fuel from a tank

Repeat the steps for procedure b above, but: i This time subtract the fuel you have

removed from the original amount of fuel in the tank to calculate the amount of fuel now in the tank.

ii Press or hold to change FUEL to the

amount of fuel now in the tank.

3 Fuel read ing is wrong or erratic:

a Check for leak s in the fuel line or in the fuel

pickup in the tank.

b Fuel sensor cable is unplugged or damaged.

Perform a visual check. DIESEL 3200: check the LED light on the underneath of flow sensor blinks when the engine draws fuel.

c The fuel R EMA INING reading is incorrect.

The fuel tank capacity (SIZE) may be incorrect, or the fuel RE MAINING setting may not have been updated after a refill. See section 5.

d Sensors require calibration (see sec tion 3-4;

diesel sensors do not normally need to be calibrated).

e The fuel flow sensor may have been

mounted too close to the fuel pump, or may be subject to excessive vibration. Refer to the installation instructions supplied with the fuel sensor.

f The fuel f low sensor damping (dA mP.F)

value is not suitable for the engine. Check that the value is not set to zero and then try increasing the value until a steady flow rate is shown (see section 3-5)

4 Speed reading is wrong or erratic:

a Speed readings require the optional speed

sensor to be installed and setup (see section 3-6).

NAVMA N

b Speed sensor cable is unplugged or

damaged. Perform a visual check.

c Speed calibration is incorrect (see sections

3-8 and 3-9).

d Interference from electrical noise may be

affec ting the measurements. Review the installation.

5 Low Fuel Alarm sounds when fuel not

low:

a The fuel REMAINING reading is incorrec t.

The fuel tank capacity (SIZE) may be incorrect, or the fuel RE MAINING setting may not have been updated after a refill. See sections 2-6. and 5.

6 The display unit fogs:

a Moist air has entered the breathing tube at

the rear of the unit. Air the boat or run the instrument with backlight fully on.

b Water has entered the breathing tube.

Return the instrument for ser vicing.

7. Flow indicates no fuel or low fuel

a FUEL 3100 : Check that the fuel cable

connectors are securely plugged in and the collar is locked in place. The collar must be locked in place to give a watertight connection.

b A fuel sensor may be clogged. If so, remove

the sensor from the fuel line and gently blow through it in the opposite direction to the fuel f low. A fuel filter between the fuel sensor and the fuel tank must be installed as per the fuel installation guide. Failure to do so will void the warranty.

c Inspect the fuel cable from end to end for

damage such as cuts, breaks, squashed or trapped sections.

d Check that the fuel filter is clean.

8 Fuel used or remaining seem inaccurate:

a In rough seas, fuel may surge back and

forth through the fuel sensor, resulting in incorrect readings. Try installing a one-way valve bet ween the fuel sensor and the fuel tank.

b The amount of fuel must b e reset after

every refuelling (see sec tion 5 ).

c The fuel tank may not ref ill to the same

capacit y each time due to air pockets. This is particularly noticable with underfloor tanks (see section 5).

d Petrol fuel sensors wear out over time and

should be replaced after every 500 0 litres of fuel.

9 A twin engine installation shows only

one flow rate:

a Check that the number of engines is set to 2

(motor in the FUEL menu, see sec tion 3).

10 There is no reading for fuel economy:

a The boat must be travelling through the

water to generate an economy reading.

b If an optional paddlewheel sensor is fitted,

check that the paddlewheel spins freely.
