Connectors on Fluid level converter

NMEA2000 Connector

M12 5-pin A-coded connector on side of unit is compatible with NMEA2000 and has standard pinout.

Figure 1: NMEA2000 M12 Male connector pinout (view from unit side)

Deutsch – sensor connector

Pinout
The pinout is shown from the unit side (female connector). Pins on housing are numbered as letters A, B and C.

Pin Type Description
A	Analog input B	Wire color – white
B	Voltage output	Wire color – red
C	Ground	Wire color – blue

Specifications
Voltage output
FLC unit features one switchable 5 V supply outputs for powering sensors. The output has automatic resettable fuse protection against overcurrent, overvoltage and short-circuit faults

Parameter Condition Min Typ Max Unit
Power output voltage	0 < Iload < 50mA	4.9	5	5.15	V
Power output current	Vout > 4.9V	0		50	mA
Short circuit current limit	Vout = 0V	50	85	130	mA
Maximum overload voltage ⁽¹⁾		-25		40	V

Note 1: Voltage forced back into the 5V output pin. Voltage outside of this range may permanently damage the device
Table 4: Power output electrical characteristics

Analog input
Fluid N2K unit features one fully configurable analog input for:

Voltage sensors: 0-5V
Resistive: European, ABYC (US) and Asian standards

Analog input has an internal switchable pullup resistor to 5V, thereby relieving the user of manual resistor installation.

Parameter Condition Min Typ Max Unit
Input resistance	0V < Vin < 30V Pullup disabled	0.9	1.0	1.1	MΩ
Input capacitance	0V < Vin < 30V Pullup disabled	0.9	1.0	1.1	nF
Operating input range		0		18	V
Absolute maximum input voltage ⁽¹⁾		-36		36	V
Internal pullup resistance	Pullup enabled		500		Ω

Note 1: Continuously applied voltage. Voltage outside of this range may permanently damage the device

Accuracy
Shown accuracy limits represent the edges of the acceptable accuracy windows for the above specified operating conditions, typical values may be lower.

Parameter Condition Value
Voltage Input Accuracy	0V < Vin < 18V	< 1 %
Voltage Input ADC Resolution		4.5 mV

Connector crimping

This chapter guides you through crimping wires into the EMU connectors provided. Tools needed are:

Crimping pliers
Wire stripper

Figure 3 shows the contents of the sensor connection kit supplied together with FLC unit. It contains (from left to right):

Endca
Housing for male terminals
3 crimp terminals
Watertight grommet

Figure 3: Sensor connection kit

For correct crimping procedure follow instruction steps bellow:
Step 1: Pull all necessary wires through grommet.

Step 2: Strip wires. Stripped length should be somewhere around 6mm.

Step 3: Insert the wire into the crimp contact and press it with pliers. The result should look like the picture below. Pliers used in this step were from Deutsch HDT-48-00.

Step 4: Insert three crimped pins into connector on dedicated place. Make sure pins are secured, test them with slight pull outwards. Take care not to mix pins functionality.

Step 5: Install water grommet on back side of connector.

Step 6: From the front side insert secure tab. This prevents crimp contacts to fell out of connector housing.

Sensor wiring

All wirings are shown with respect to female connector on Fluid N2K.

Resistive type sensors

Use only ground and analog input connections. Polarity on sensor side is not important.

Voltage output type sensors

All three contacts are used in this configuration. V+ and V- terminals are for powering fluid level sensor and analog input measures voltage.

Configuration and calibration

To operate properly, FLCD must be configured prior use. Configuration can be performed via one of LXNAV compatible devices. Configuration menu is accessible under settings menu:
Settings->Network->Connected Devices->LXNAV EMU->Device setup

Configuration

Inside this page user can choose between different options for particular FLC.

Input type
User can select:

None
Fluid level
Voltage reference

Fluid level sensor type
Some standard and generic available options:

Resistive 240-33 Ohm (US)
Resistive 3 – 180 Ohm (EU)
Resistive 105 – 5 Ohm (Asia)
Resistive 2 – 90 Ohm (EU)
VDO 0.5 – 4.5 V
Generic voltage 5 V
Generic voltage with reference

Fluid type
Types of measured fluid:

Fuel
Fresh Water
Waste Water
Live Well
Oil
Black Water (Sewage)
Fuel (Gasoline)

Tank capacity
Textbox for capacity of tank.

Calibration

When calibrating fuel level sensor it is necessary to follow some rules. At the beginning go to calibration menu that can be found under this path:
Settings->Network->Device calibration->Fluid level->Fluid level

For the first calibration fuel or any other fluid tank has to be empty. At the beginning there are already two existing calibration points added to calibration table – 0 liters, 0 % and 100 liters, 100 %. Maximum capacity value depends on selected value in configuration menu. User can add up to 10 additional calibration points which increases accuracy of indication due to non-linearity of sensor or different shapes of tanks.
