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 boats 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 owners sole responsibility to install and use the instrument and its sensor(s) in compliance with these requirements.

1 Introduction

This manual describes 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. 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 after manually removing fuel, to maintain accurate readings (see section 5). The FUEL 3100 and DIESEL 3200 are part 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 instruments installation and operation manual before installing or using this kit.

This manual describes how to install, set up and operate the instruments. For more information, refer to the separate Flow Sensor Installation Manual (for the FUEL 3100 and petrol systems) and Diesel Flow Sensor Installation and Operation Manual (for the DIESEL 3200 and diesel systems); this manual has extensive information on understanding and optimising your diesel boats 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

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 flow 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 friction, fuel proof plastic. There are no fine pointed shafts and jewelled bearings to get worn or hammered by diesel pulsing. Each engine is fitted with two fuel flow sensors, to measure fuel supply and return.The system calculates the engine consumption, compensating for pulsing from diaphragm lift pumps, different fuel temperatures in the supply and return lines and the flow characteristics of the sensors.

3-4 Fuel calibration (CAL.F)
To calibrate a fuel ow 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 ow sensors after installation and again after the rst 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 ow 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 two portable tanks, or at dierent times using one portable tank. To calibrate an engines fuel ow sensor: Connect the portable tank to the engine through the fuel ow sensor. Reset USED: i Press one or more times until USED is displayed.

To calibrate: 3

Select the SPEED setup menu, then select CAL.L, the distance travelled. If the value of CAL.L does not match the known distance, 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 boats speed changes.

4 Installation

Correct installation is critical to the performance of the unit. It is vital to read the entire installation section of this manual, and the documentation that comes with any optional other parts, before starting the installation. For more information, refer to the installation instructions supplied with the sensor, or consult your Navman dealer.

4-1 Tank and engine options
There are three options for the FUEL 3100 and the DIESEL 3200. A FUEL 3100 uses one sensor to measure fuel consumption. The DIESEL 3200 uses two sensors to measure fuel consumption, a sensor in the supply line and a sensor in the return line (see section 1-1). To configure the unit for different tank and engine options, set dUAL and motor in the

16 NAVMAN

FUEL menu and for twin motors identify each engine in the dSL SEn menu by alternately removing power from the flow sensors as described in this section. Note: Twin fuel tanks connected by an open balance pipe should be configured as a single fuel tank.

4-2 The display unit

4-3 The fuel flow sensor(s)
Install the fuel flow sensor(s) following the instructions 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 instructions in the Fuel Sensor Installation 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 next page).
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. 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.
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 boats structure. If in doubt, consult a qualified 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 engines 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

is available wire the unit through each ignition system seperately using an On/On switch. Alternatively wire it through a seperate switch to the vessels 12 V power supply. The units must 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 instruments 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.
4-6 Systems of several 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 connected by NavBus: Data from a sensor connected to one instrument is available to all instruments. If the units, alarms or calibration are changed in one instrument, then the values will automatically change in all instruments of the same type. Each instrument can be assigned to a group of instruments by setting a group number between 0 and 4. Then, if the backlight is changed in an instrument in groups 1, 2, 3 or 4, it will automatically change in all the other instruments in that group. However, changing the backlight setting in an instrument in group 0 will not affect any other instrument. To assign the FUEL 3100 or DIESEL 3200 to a group, set GrouP in the LAmP menu (see section 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 Installation and Operation Manual. NMEA NMEA is an industry standard for marine instrument connections. 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 installation
To check out the installation: 1 Power on the boat and any other instruments. Check the instruments work properly. Enter the setup data (see section 3). Set dUAL, motor , and InPUt first, then enter the rest of the setup data. For boats with twin 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). On boats with twin engines, check the installation of the port and starboard fuel sensors: DIESEL 3200: Start the port engine. Check the LED lights under the sensors are blinking. This indicates the sensors are operating correctly. Confirm the fuel flow is being displayed as port engine fuel usage 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: Start the port engine. Confirm the fuel flow is being displayed as port engine fuel usage on the instrument. If it is being displayed as starboard engine fuel usage, reconfigure the settings (see section 3-3). FUEL 3100 only: Calibrate the fuel sensor(s) (see section 3-4). If a paddlewheel speed sensor is connected, calibrate it (see sections 3-8 and 3-9). Take the boat for a trial run and check the unit is displaying the correct data.

FUEL 3100: Recalibrate the FUEL 3100s fuel sensor(s) after the first 100 engine hours (see section 3-4).
4-8 Resetting to factory defaults
To reset to factory defaults: 1 Turn the power off. 2 Hold ENT + while turning on the power and for at least five seconds after.
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, RANGE 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 3 When you fill a tank Fill the tank. Press If the boat has twin tanks, press ENT until the display shows the name of the tank you have filled, PORT or STBD. Press and together. If the boat has twin tanks and you are filling the other tank as well, repeat the above steps.
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. When you fill or part fill a tank Before adding or removing fuel, press ESC and ENT together, then press until the FUEL setup menu is displayed. Press ENT, then press or FUEL data is displayed. until the
until REMAINING is displayed.
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.
Note: If you follow procedure b above every time you add fuel, then a small error will accumulate, because it is hard to measure exactly how much fuel you add. To avoid this, about every ten tankfulls of fuel, fill the tank and follow procedure a. c i When you remove fuel from a tank 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. Press or hold to change FUEL to the amount of fuel now in the tank. Repeat the steps for procedure b above, but:
Write down the number displayed, FUEL, which is the amount of fuel now in the tank. Add fuel to the tank, writing down how much you add. 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 FUEL to the amount of fuel now in the tank. Press ENT, then press ESC to return to the main display. 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 manufacturer for repair. Please follow this troubleshooting section before contacting the nearest Navman dealer. There are no user serviceable 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 service centre approved by Navman NZ Limited. Users who service the unit themselves will void the warranty. More information can be found on our website: www.navman.com 1 a b c Instrument will not turn on: Power/data cable is damaged or disconnected. Perform a visual check. Fuse is blown or circuit breaker has tripped. Replace the fuse or reset the circuit breaker. Battery voltage is outside the range 9 to 30 V DC. Check the battery voltage using a multimeter. The word SIM flashes at bottom left corner of screen, values displayed are unexpected: The instrument is in simulation mode (see section 2-9). 4 a f 3 a b Fuel reading is wrong or erratic: Check for leaks in the fuel line or in the fuel pickup in the tank. 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. The fuel REMAINING reading is incorrect. The fuel tank capacity (SIZE) may be incorrect, or the fuel REMAINING setting may not have been updated after a refill. See section 5. Sensors require calibration (see section 3-4; diesel sensors do not normally need to be calibrated). 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. The fuel flow sensor damping (dAmP.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) Speed reading is wrong or erratic: Speed readings require the optional speed sensor to be installed and setup (see section 3-6).

NAVMAN 21

Speed sensor cable is unplugged or damaged. Perform a visual check. Speed calibration is incorrect (see sections 3-8 and 3-9). Interference from electrical noise may be affecting the measurements. Review the installation. Low Fuel Alarm sounds when fuel not low: The fuel REMAINING reading is incorrect. The fuel tank capacity (SIZE) may be incorrect, or the fuel REMAINING setting may not have been updated after a refill. See sections 2-6. and 5. The display unit fogs: Moist air has entered the breathing tube at the rear of the unit. Air the boat or run the instrument with backlight fully on. Water has entered the breathing tube. Return the instrument for servicing. 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. 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 flow. 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. Inspect the fuel cable from end to end for damage such as cuts, breaks, squashed or trapped sections. Check that the fuel filter is clean.
Fuel used or remaining seem inaccurate: In rough seas, fuel may surge back and forth through the fuel sensor, resulting in incorrect readings. Try installing a one-way valve between the fuel sensor and the fuel tank. The amount of fuel must be reset after every refuelling (see section 5 ). The fuel tank may not refill to the same capacity each time due to air pockets. This is particularly noticable with underfloor tanks (see section 5). Petrol fuel sensors wear out over time and should be replaced after every 5000 litres of fuel. A twin engine installation shows only one flow rate: Check that the number of engines is set to 2 (motor in the FUEL menu, see section 3). The boat must be travelling through the water to generate an economy reading. If an optional paddlewheel sensor is fitted, check that the paddlewheel spins freely.

Warnings for fuel types

Navman petrol flow sensors 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 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. The diesel sensors can be used in 12 or 24 V systems. Some display units such as the DIESEL 3200 require 12 V DC. Before connecting any power greater than 12 V DC to the display unit, check that the unit can tolerate the intended voltage.

Appendix C - Speed through water and over ground
Different instruments measure different boat speeds. A paddlewheel sensor measures boat Speed Through the Water (STW). A GPS measures boat Speed Over the Ground, ie over the bottom of the water (SOG). If there is a current, these speeds will be different, as explained below. Therefore, the readings for speed, log, trip log, economy and range will depend on whether the speed input is STW or SOG and if the current is constant.
When the current is from ahead, speed over ground is less than speed through water
STW is 10 knots Current 4 knots

STW is 10 knots

Gives an SOG of 6 knots
Gives an SOG of about 8 knots

Current 4 knots at 45

For this example: If the boat travels for one hour, uses 3 gallons of fuel and has 50 gallons of fuel left: Speed Using STW: Using SOG: 10 knots 6 knots Log 10 nm 6 nm Economy 3.3 nm / gal 2.0 nm / gal Range 165 nm 100 nm
When the current is from behind, speed over ground is more than speed through water

Gives an SOG of 14 knots

Gives an SOG of about 13 knots
