NMEA 2000 Engine Monitoring Unit - EMU-1

All warnings and notices must be followed to ensure the correct operation of the EMU-1. Incorrect

installation may invalidate the guarantee.

It is highly recommended that all of the installation instructions are read before commencing the installation.

There are important warnings and notes throughout the manual that should be considered before the

installation is attempted.

Warning 1: Accuracy

The Actisense EMU-1 is designed to reliably measure voltage levels on senders and sensors; the accuracy is reliant

upon the correct installation and the correct conguration of the EMU-1. Furthermore the information present in the

associated NMEA 2000 PGN’s which are output by the EMU-1 depends on conguration parameters being set correctly.

Therefore, the EMU-1 should only be used as an aid to vessel monitoring, control or navigation and should not be used

as a replacement for traditional aids and techniques.

Warning 2: Installation and Operation

This product must be installed and operated in accordance with the instructions provided. Failure to do so could result

in personal injury, damage to your boat and/or poor product performance.

Warning 3: Installation Code of Practice

When wiring the power supply to the EMU-1 ensure the isolation switch is off. Wiring the EMU-1 while the connection is

live may damage the EMU-1 and is in breach of the guarantee.

All wiring should be in accordance with the regional code of practice for installations.

Warning 4: Firmware Updates

It is highly recommended that the Firmware is kept up to date in the EMU-1. Please check to ensure your EMU-1

shipped with the latest Firmware. You can do this by locating the manufacturers software ID for your EMU-1 on the

network list found in most NMEA 2000 displays or using our freely available NMEA Reader. The latest rmware version

number and details of supporting software such as NMEA Reader can be found on the EMU-1 downloads web page.

Warning 5: NGT-1 Support

It is highly recommended that an NGT-1 (either USB or ISO variants) be available for every EMU-1 installation. The

NGT-1 can be used to update the Firmware, connect to the Conguration Tool and display data on a PC running

compatible software. Details of the NGT-1 can be found here www.actisense.com/NGT-1.

Warning 6: Mounting Requirements

Select a at location to mount the EMU-1. Mounting on a contoured surface may cause damage to the case.

Do not mount the EMU-1 while the device is powered.

Do not mount the EMU-1 while the NMEA 2000 cable is connected.

Do not mount the EMU-1 while the engine cable harness is connected.

Note that the terminals are pluggable for easy disconnection when mounting or removing the EMU-1.

Warning 7: Mounting Locations

Do not mount the EMU-1 in the same plane as transmitting or receiving antennas.

Do not mount the EMU-1 close to an electronic compass.

Warning 8: Wire Noise

Avoid running noisy wires (such as those connected to ignition coils) adjacent to sensitive gauge or alarm wires as

noise may be induced into these wires and this may result in inaccurate measurements and corresponding inaccurate

data being output to the NMEA 2000 bus.

The EMU-1 converts data from analogue engine senders into NMEA 2000 compatible data, allowing modern NMEA

2000 display devices to monitor the engine data and associated gauge levels aboard a vessel.

The unit has been designed to connect in parallel to an existing gauge, so existing instruments can still be used. The

EMU-1 can also be used straight from the sender without a gauge being present. In effect the EMU-1 can be installed

for most engine makes and models.

The EMU-1 provides 6 dedicated Gauge inputs, capable of measuring the output from the required engine senders. The

unit also provides 4 Alarm inputs (e.g. high temp, low pressure), 2 Tacho inputs, and 2 user denable Auxiliary inputs.

See the EMU-1 FAQs section to nd which senders are supported. See “Table 3 - NMEA 2000 PGN List” on page 18 for

a list of NMEA 2000 PGNs that the EMU-1 supports. Refer to the EMU Cong Tool User Manual on the EMU-1

downloads page for instructions on how to congure the EMU-1.

Selecting a Mounting Location

“Figure 2 - Example of a Typical Installation” shows an example installation. This gives an idea of the connections

that need to be made to install the EMU-1. All these connections need to be considered before selecting an installation

location. Refer to “Warning 7: Mounting Locations” on page 7.

Installations without Gauges

The EMU-1 can be used on senders where the analogue

gauges are not present, connecting directly to the sender

to be measured. In this case it is recommended that the

EMU-1 be mounted close to the engine. The cable length

between the sender and the EMU-1 should typically not

exceed 2 metres.

Installations with Gauges

The EMU-1 can be used in parallel with existing gauges to

compliment the information already displayed. In this case

it is recommended that the EMU-1 be mounted close to

the gauges (instrument panel). The cable length between

the gauges and the EMU-1 should typically not exceed 2

metres.

NMEA 2000 Networks

NMEA 2000 devices will only communicate with each

other when connected to a powered and correctly

terminated NMEA 2000 network. It is not enough to simply

connect two NMEA 2000 devices directly together.

All networks need to be powered and terminated correctly

to allow data to be transmitted reliably on the network.

T-Pieces are needed to connect each device to the

network. Additional cable lengths can be used between

any of the connectors to extend the length of the network.

Ensure the NMEA 2000 rules for cable length are adhered

to, see “Table 1 - NMEA 2000 Cable Length Rules”.

Table 1 - NMEA 2000 Cable Length Rules

Cable Type Max

Length

Per drop cable 6m

Sum of all drop cables 72m

Micro Backbone (terminator to terminator) 100m

Mini Backbone (terminator to terminator) 200m

NMEA 2000 Minimum Network

Requirements

All NMEA 2000 networks require a 12V DC supply.

In addition, a correctly functioning network will require the

following components :

• 1 x Power-T

• 2 x Terminating Resistors

• 2 x T-Pieces (one per connected device)

• 2 x NMEA 2000 Devices (such as the EMU-1)

All the required network parts can be supplied by

Bulkhead Mounting

• Use the EMU-1 as a template to locate and mark the drill holes for mounting. Do not attempt to drill the holes while

the EMU-1 is in position.

• Refer to “Warning 6: Mounting Requirements” on page 7.

• Four M3.5 stainless steel pan-head screws are provided with the EMU-1 for mounting to the bulkhead. If these

screws are lost, suitable alternatives may be used. Note: Using larger screws can damage the housing and invalidate

the guarantee.

• Secure directly to a bulkhead using the mounting screws provided with the unit.

Refer to the “Dimension Diagram” on page 18.

DIN Rail Mounting

Requirements:

• An Actisense DIN Rail Kit (not included with the EMU-1) Part Code: DIN-KIT-1

• A top hat rail, type EN 50 022 or a G section rail, type EN 50 035.

Mounting using a different rail type or an alternative mounting kit may breach the terms and conditions of the guarantee.

Method:

• Refer to “Warning 6: Mounting Requirements” on page 7.

• Attach the mounting kit to the base of the EMU-1 with the kit supplied screws. There is provision to mount the EMU-1

vertically or horizontally (recommended). Using alternative screws may not be reliable or may result in damage to the

housing and invalidate the guarantee.

Figure 5 - Mounting Options

The EMU-1 has a male Micro connector as specied by the NMEA 2000 standard. This allows the EMU-1 to be

connected directly to an NMEA 2000 bus without complication. If you are using an alternative proprietary CAN bus

network, a suitable adapter cable will be required. It is recommended that the manual for any proprietary CAN bus

network devices be consulted to determine the suitability of connecting an NMEA 2000 device such as the EMU-1.

A certied NMEA 2000 cable is recommended for connection to the EMU-1. Ensure that the drop cable is no longer than

6 meters from the NMEA 2000 backbone, see “Table 1 - NMEA 2000 Cable Length Rules”. The cable connector

should be screwed securely to the EMU-1 connector to ensure reliable operation. It is recommended that the supplied

NMEA 2000 dust cover is left in place until the EMU-1 is connected to the NMEA 2000 network.

There are a number of indicator LEDs that can be used to diagnose the NMEA 2000 connectivity. Please refer to,

“NMEA 2000 Power LED (Red)”, “NMEA 2000 Rx LED (Green)” and “NMEA 2000 Tx LED (Orange)” on page 17

Gauge Input Connections

There are six Gauge inputs which are designed to be connected to existing engine senders (resistive type) either with

or without the gauge connected. In the case where no gauge is connected the EMU-1 automatically provides a feed to

the sender. A dual station sender must always have two gauges connected to it: the EMU-1 cannot replace one or both

of those gauges. If it is required to remove one or both gauges, the dual station sender will need to be replaced with a

single station sender.

Insulated Terminal Sender with Gauge

“Figure 7 - Gauge Input Connection Examples” G1 Input:

• The gauge power connection is connected to the same positive voltage supply as the EMU-1.

• The gauge ground connection is connected to the same ground as the EMU-1.

• The gauge signal connection is connected to the sender signal line.

• The sender return connection is connected to the same ground as the EMU-1.

• The EMU-1 Gauge input is connected to the gauge signal line, typically with a cable run that does not exceed 2

metres with a minimum 0.5mm wire diameter (24 AWG).

Insulated Terminal Sender without Gauge

“Figure 7 - Gauge Input Connection Examples” G2 Input:

• The senders return connection is connected to the same ground as the EMU-1.

• The EMU-1 Gauge input is connected to the sender signal line, typically with a cable run that does not exceed 2

metres with a minimum 0.5mm wire diameter (24 AWG).

Standard Grounded Sender with Gauge

“Figure 7 - Gauge Input Connection Examples” G4 Input:

• The gauge power connection is connected to the same positive voltage supply as the EMU-1.

• The gauge ground connection is connected to the same ground as the EMU-1.

• The gauge signal connection is connected to the sender signal line.

• The sender chassis is connected to the same ground as the EMU-1.

• The EMU-1 Gauge input is connected to the gauge signal line, typically with a cable run that does not exceed 2

metres with a minimum 0.5mm wire diameter (24 AWG).

• The sender chassis is connected to the same ground as the EMU-1.

• The EMU-1 Gauge input is connected to the sender signal line, typically with a cable run that does not exceed 2

metres with a minimum 0.5mm wire diameter (24 AWG).

Note: The examples given are not limited to the input they are shown with. E.g. the G1 Input example can also be

connected to any of the other Gauge inputs. Each input will accept any of the gauge / sender examples described.

Figure 7 - Gauge Input Connection Examples

Alarm Input Connections

There are four Alarm inputs which are designed to be connected to existing alarm type switches. The EMU-1 can be

used with or without the alarm indicator (e.g. lamp or buzzer) connected. If there is no alarm indicator, a suitable resistor

can be used in its place. For 12 V supplies it is recommended to use a 1 kΩ, ¼ W resistor, for 24 V supplies it is

recommended to use a 1 kΩ, 1 W resistor. Some alarm switches are incorporated into their relevant sender and are

also suitable to connect to the EMU-1.

There are several different combinations of switch type and wiring method that the EMU-1 Alarm inputs are compatible

with.

Supported Switch and Installation Types

• Normally Open switches (see Figure 8 Examples A1 and A4).

• Normally Closed switches (see Figure 8 Examples A2 and A3).

• Active High (see Figure 8 Examples A3 and A4).

• Active Low (see Figure 8 Examples A1 and A2).

Critical Circuit Requirements

• The switch circuits positive supply is the same as the supply used to power the EMU-1.

• The switch circuits negative supply (ground) is the same as the EMU-1 power ground.

• The switch circuit has a load (e.g. buzzer, lamp or resistor) in series with the switch between the positive supply and

ground.

• The EMU-1 Alarm input is connected between the switch and the load (e.g. buzzer, lamp or resistor).

Additional Information

• If the EMU-1 is connected at the switch, the cable run should not typically exceed 2 metres.

• If the EMU-1 is connected at the buzzer or lamp, the cable run should not typically exceed 2 metres.

• If replacing the buzzer or lamp with a resistor this should be done as near to the EMU-1 as possible, in this case the

cable run should not typically exceed 2 metres.

Please refer to the examples shown in “Figure 8 - Alarm Input Connection Examples”

Note: The examples given are not limited to the input they are shown with. E.g. the A1 Input example can also be

connected to any of the other Alarm inputs. Each input will accept any of the switch and installation types listed above.

Each input will require the type of installation to be selected using the conguration tool provided.

Power Requirements

Connecting the Power

• Refer to “Warning 3: Installation Code of Practice” on page 7.

• The EMU-1 should be powered from the same supply as the gauges / senders.

• The EMU-1 requires a power source providing between 9 and 35 Volts DC.

• Connect the positive supply wire to the ‘PWR +VE’ screw terminal of the EMU-1.

• Connect the negative / ground supply wire to the ‘PWR GND’ screw terminal of the EMU-1.

• Once connected, turn on the supply. For details on the Power indicator, refer to “EMU-1 Power LED (Blue)” on

page 17.

Grounding Requirements

All measurements are taken relative to the ground power pin of the EMU-1. For both safety and accurate measurements,

it is important to understand the vessels grounding to ensure the EMU-1 is grounded at the appropriate place. The

EMU-1 should always be connected to a good ground connection point which is not susceptible to ground noise. It is

important that the EMU-1 ground is the same as the engine ground.

The EMU-1 should only be used with standard negative ground DC systems.

When the EMU-1 is connected to senders only (no gauges are connected), it is important that the EMU-1 ground is the

same as the engine ground.

Dual Engine Power Supply

When monitoring two engines using a single EMU-1, both engines and the EMU-1 must share the same power supply

if the gauges are to remain in circuit. If a seperate power supply must be used for each engine, either a seperate EMU-

1 is required for each engine or the gauges will need to be removed for the EMU-1 to correctly monitor the sensors of

both engines.

Tacho Input Connections

Auxiliary Input Connections

There are two Auxiliary inputs which are included for future expansion. Currently these inputs are disabled.

Ignition Coil

• Connect the negative connection of the ignition coil to the positive Tacho input of the EMU-1.

• The negative Tacho input of the EMU-1 should be left unconnected.

• Refer to the connection in “Figure 9 - Tacho Input Connections” and “Figure 10”.

• For calibration the PPR or the number of cylinders will need to be entered in the conguration

tool.

Alternator

• Connect the Tacho (AC Tap) or ‘W’ connection of the alternator to the positive Tacho input of

the EMU-1.

• The negative Tacho input of the EMU-1 should be left unconnected.

• Refer to the connection in “Figure 9 - Tacho Input Connections” and “Figure 11”.

• For calibration the PPR or the number of poles and the pulley ratio will need to be entered in

the conguration tool.

Hall Effect and Electronic Pulse Senders

• Connect the signal line of the sender to the positive Tacho input on the EMU-1.

• The negative Tacho input of the EMU-1 should be left unconnected.

• Refer to the connection in “Figure 9 - Tacho Input Connections” and “Figure 12”.

• For calibration the PPR or the number of teeth on the y wheel will need to be entered in the

conguration tool.

Inductive Senders

• Connect the positive signal line from the sender to the positive Tacho input of the EMU-1.

• Connect the negative signal line from the sender to the negative Tacho input of the EMU-1.

• Refer to the connections in “Figure 9 - Tacho Input Connections” and “Figure 13”.

• If the negative signal line is not available, the negative Tacho input of the EMU-1 should be left

unconnected, and the sender should be connected to the same ground as the EMU-1.

• Refer to the connection in “Figure 9 - Tacho Input Connections” and “Figure 12”.

• For calibration the PPR or the number of teeth on the y wheel will need to be entered in the

conguration tool.

Battery Voltage Sensing

The EMU-1 automatically measures the voltage across it’s supply inputs (marked ‘PWR +VE’ and ‘PWR GND’). This

value is provided in the battery status PGN.

Calculating Tacho PPR

The EMU-1 conguration tool allows the “ratio” to be congured. This ratio is usually referred to as the PPR (Pulses Per

Revolution). The engine manufacturer will usually be able to supply this ratio so it should not need to be calculated.

For an Alternator (“W”. “R” or “AC”) terminal connection it can be calculated from:

PPR = (Crank pulley diameter / Alternator pulley diameter) × (No.of poles in Alternator / 2)

For an inductive sender it is derived from the number of teeth on the ywheel:

PPR = No.of teeth on ywheel

For an ignition coil it can normally be calculated from

PPR = (No.of cylinders × 2) / (No.of strokes × No.of ignition coils)

Note: Wire colours are for reference only

There are two Tacho inputs which are designed to be connected

to existing engine senders either with or without the gauge

connected.

The Tacho inputs must be calibrated in the conguration tool.

The Pulses per Revolution (PPR) must be entered to allow the

correct RPM to be calculated by the EMU-1.

There are several different sender options that can be used to

generate NMEA 2000 RPM data. Each supported type is listed

below along with the information required to congure the input

using the conguration tool.

NMEA 2000 Engine Monitoring Unit - EMU-1

The conguration loaded into the EMU-1 is detailed in “Table 2 - Default EMU-1 Input Conguration”.

Connecting to any other type of sender without conguring the unit is likely to cause incorrect data to be output to the

NMEA 2000 bus. See “Conguring the EMU-1” for how to congure the unit.

Conguring the EMU-1

Conguration Requirements

To congure the EMU-1 the following is required:

• A working NMEA 2000 network.

• An NGT-1 (either the ISO or USB variant).

• A PC running the Actisense EMU-1 Conguration Tool. The tool is provided on the CD but it is recommended that the

latest version is downloaded from www.actisense.com/EMU-1/Downloads.

• Information about the senders/gauges being connected. Note: For the Tacho inputs additional information will be

needed, see “Tacho Input Connections” on page 14.

All instructions for conguring the EMU-1 can be found in the help menu of the conguration tool software.

Troubleshooting Guide

The majority of issues can be resolved by conrming the EMU-1 is connected correctly, refer to the LED

descriptions below to conrm the power and NMEA 2000 connections are operational. Once these connections

are conrmed, the analogue connections and conguration need to be checked. Refer to “Conguring the

EMU-1” on page 16.

LED Indicators

EMU-1 Power LED (Blue)

There is a power LED located above the power supply terminal connectors which is visible through the connector cover.

The LED ashes blue to indicate power and denotes the active mode of the unit.

The LED ashes 5 times a second when in Bootloader mode. This should be seen for the rst 2 seconds following

power on and when ‘connected’ to ActiPatch for updating. If the LED continues to ash 5 times a second after initial

power on, the unit no longer has its Firmware. In this case, connect the EMU-1 to Actipatch and reinstall the Firmware.

The LED ashes once a second when in Normal mode, this indicates the Firmware is running and the EMU-1 can be

congured and will connect to an NMEA 2000 network when available.

NMEA 2000 Power LED (Red)

There is a red LED located near to the NMEA 2000 connector which is visible through the main body of the EMU-1.

When the EMU-1 is connected to an NMEA 2000 network with a suitable power supply the LED will light. This does not

indicate that the bus is correctly terminated or that there is any data on the network. The LED will light regardless of

whether the EMU-1 has power to the terminal connections. The EMU-1 requires power on both the terminals and the

NMEA 2000 bus to function correctly. These two power supplies do not need to be the same or have the same ground.

The NMEA 2000 bus and EMU-1 power are isolated from each other within the EMU-1 as required in the NMEA 2000

specication.

NMEA 2000 Rx LED (Green)

There is an NMEA 2000 data receive LED located to the left of the terminal connectors which is visible through the

connector cover. The LED ashes green on reception of an NMEA 2000 PGN message that is in the PGN list, see

“Table 3 - NMEA 2000 PGN List” on page 18.

As this is a small list, a blank LED should not be interpreted as a failure to connect to the NMEA 2000 bus without

conrming that compatible PGNs are present on the bus.

NMEA 2000 Tx LED (Orange)

There is an NMEA 2000 data transmit LED located to the left of the terminal connectors which is visible through the

connector cover. The LED ashes orange on transmission of an NMEA 2000 PGN message.

Technical Support and the Returns Procedure

All installation instructions and any warnings contained in this manual must be applied before contacting Actisense

technical support. If the troubleshooting guide did not help resolve the problem and an error persists, please contact

Actisense technical support to help trace the issue before considering the return of the product. If Actisense support

concludes that the EMU-1 unit should be returned to Actisense a Returns Number will be issued by the support engineer.

The Returns Number must be clearly visible on both the external packaging and any documentation returned with the

product. Any returns sent without a Returns Number will incur a delay in being processed and a possible charge.
