INTRODUCTION

The Offshore System’s NMEA2000® part number 4291 4–20mA Tank Level Adaptor is designed to monitor any 4–20mA level sensor including Fuel, Fresh Water, Waste Water, Live Well, Oil &

Black Water senders on the NMEA2000® network.

The Tank Sender Adaptor is water resistant but NOT waterproof. It is designed to be located in a dry and protected location. It is very important that it is installed and set up correctly according to this manual. Please read and follow the installation and setup instructions carefully to achieve the best results.

1 x 4291 NMEA2000® 4 - 20mA Tank Level Adaptor

1 x 4291 User Manual (This document)

2.2 MOUNTING THE UNIT

2.3 CONNECTING THE NMEA2000® CABLE

The unit is connected to the NMEA2000® network by the 5 way micro C plug on the front.

Carefully attach the network drop cable to this plug and hand tighten until it is fully seated.

Take care to match the orientation of the pip inside the socket to the recess inside the drop cable socket. The other end of the drop cable should be connected to a suitable Tee connector on the NMEA2000® network backbone cable.

2.5 CONFIGURATION

2.5 The following items can be configured on the 4291 Adaptor.

2.5.1 DEVICE INSTANCE

It is possible to choose from 6 tank types on the 4291 Adaptor. Selection of tank type is possible to set by turning the small rotary switch (SW1) with a small screw driver. Valid tank types are from “0” through to “5”. By selecting invalid tank type, the device stops to sending of NMEA tank level messages and the red LED shows the wrong selection.

.5.2 TANK TYPE

It is possible to install 16 units of 4291 Tank Level Adaptor for each tank type on the

NMEA2000® network so they need to each have a unique Device Instance Address. The Device

Instance of each unit is set by turning the small rotary switch (SW2) with a small screw driver.

Valid Device Instances range from “0” through to “F”.

2.5.3 CALIBRATION VALUES

The 4–20mA Tank Level Adaptor can operate in either Level or Volume modes. Select your desired value with SW2 from the table below.

Level Mode – In this mode the adaptor sends pure (unmodified) level percent.

Volume Mode – In this mode, the level percent is modified by volume table of the device.

To select your desired operation mode, set SW1 to position and actuate reed switch, which is positioned under SW1 with a magnet.

The 4–20mA Tank Level Adaptor can be calibrated to operate between the set Empty & Full level. To set Calibration Values, when the tank is at the empty level, set SW1 to ‘E’ and acutate magnetic switch. When tank is at Full level, set SW2 to ‘F’ and actuate magnetic switch.

Empty Level – In this mode, during the actualization, the device stores the current tank level as the empty level . Full Level – In this mode, during the actualization, the device stores the current tank level as the full level.

Once the value selected correctly, setting Not Used values will not take effect on the device.

CALCULATING THE TANK LEVEL

The Tank Level value calculated as percentage of the fluid level, between the empty and full level values. In Volume Mode this value modified by the Volume Table of the device, which is represents the shape of the tank. The 4291 can be factory programmed with up to 100 points of volumetric information and to transmit the remaining fuel VOLUME percentage if the user chooses

PERCENTAGE LEVEL MODE output from 0 – 100% indicates the percentage level of the fluid in the tank. The user can tell when the unit is in ‘Level Mode’ because the blue LED flashes ONCE every 2.5 seconds when a level message has been sent.

PERCENTAGE VOLUME MODE output from 0-100% indicates the actual fluid volume within the tank taking allowance for the tanks internal shape. The user can tell when the unit is in ‘Volume Mode’ as the blue LED flashes twice rapidly every 2.5 seconds when a volume message has been sent.

The accuracy of the tank level value is +/- 1 % in case of linear volume table. Extreme tank shapes can cause bigger differences because of multiplying of the offset error of the sensor.

The Volume Mode PGN message is exactly the same as the Level Mode PGN message which means that the volume can easily be shown on any NMEA2000 display that accepts Fluid Level

PGNs from tank senders. The Volume Mode Tank data can be entered from any Offshore Systems

Display that is equipped to set up this data. Please contact us for more information on these displays. It can also be set up at manufacture if the information is made available at the time of ordering.

LEVEL MODE can be set with the Tank Type Switch SW1 by setting the switch to ‘C’ and then placing a small magnet on the ‘Magnet Calibration’ position for 5 seconds. The blue LED flashing

2 times in a second to confirm that the magnet is in the proper position. The magnet can be remove after 5 seconds and the blue LED will Light up for 2 seconds to indicate that the unit registered the settings. Then return the switch to it’s original position and the sender will transmit level messages as indicated by the blue LED flashing ONCE briefly every 2.5 seconds.

VOLUME MODE can be set with the Tank Type Switch SW1 by setting the switch to ‘D’, then placing the magnet on the ‘Magnet Calibration’ position for 5 seconds. The blue LED flashing

2 times in a second to confirm that the magnet is in the proper position. The magnet can be remove after 5 seconds and the blue LED will Light up for 2 seconds to indicate that the unit registered the settings. When the switch is returned to it’s original positions the sender will transmit Volume messages as indicated by the blue LED flashing rapidly TWICE every 2.5 seconds.

MAINTENANCE

● Clean the unit with a soft cloth.

● Do not use chemical cleaners as they may remove paint or markings or may corrode

the enclosure or seals.

● Ensure that the unit is mounted securely and cannot be moved relative to the

mounting surface. If the unit is loose, tighten the mounting screws.

● Check the security of the cables connected to the NMEA 2000® connector, tighten if

necessary.

● Check the security of the Crimp receptacle to the 4291 Spade Terminals
