2.4 CONNECTING THE LED POWER INPUT CABLES TO THE UNIT
The unit has both a primary navigation lamp power connection and a secondary power
connection with automatic fall back if the primary power fails. Each power source has a local
green LED indicating power good from that source. The Controller will power the LED Navigation
lights from either a 12 or a 24 Volt power source. The terminal block on the lower left hand
front panel allows for the two separate connections. Please note that each input is galvanically
isolated from the other for safety. The Cage Clamp style terminal blocks can accommodate wire
diameters from x to y.
Each channel of the unit can power up to 750mA with a total over any unit of 2.5 Amps so it is
important to size the wires and their protective fuses to be able to handle a maximum of 2.5
Amps.
2.5 CONNECTING THE LED NAVIGATION LAMPS TO THE UNIT
The 5971 and each 5972 if tted each have 8 LED light control channels for connecting the
navigation lights to the unit. These connections are arranged along the lower front edge of each
unit with both the positive and negative connections arranged sequentially as shown.

2.6 PANEL CONTROLS AND INDICATORS
Each unit controls eight channels and has the following controls and indicators:
The override switch allows full manual control of each Navigation LED channel with a toggle
switch that can either Turn OFF the channel, override the channel ON or AUTO to allow the
channel to be system controlled. This ensures that the navigation lights are always controllable
even if the system logic fails.
The Calibration button has two functions: If pressed for a short time it will recalibrate the
channel by measuring the standard usage current and recording it to identify if the navigation
lamp has partial LED failures or the connection goes high resistance or goes open circuit. Details
of this function are detailed in a later section.
The second function is activated if the button is held down for 8 seconds or more when the
navigation light power on hours will be zeroed when a new navigation light is installed. Details
of this function are described below.
Each channel has a “write on area” for the installed to write the navigation lamp identity with
a suitable marker for future reference.
Note that LED connections are polarity sensitive and must be correctly wired to work. Each
connection can supply 750mA with a maximum total current from each unit of 2.5 Amps.
After connecting the LEDs the unit should be calibrated for each channel which allows the
unit to learn the current draw of each channel and warn if the LED has a partial failure or the
connection is broken or corroded. See the next section for calibration procedure.
The units also track the total power on hours for each LED circuit and warns if they are
exceeded so the LED lamp may be renewed.

Each channel also has an channel status indicator LED that shows the following
characteristics:
2.7 CALIBRATION
Each channel of the 5971 and 5972 can be calibrated to measure the resistance of the
connecting wires and current consumption of the LED navigation lamp. Then as the channel
is turned on it will automatically measure the current being drawn and warn if the lamp has
any failed internal LEDs or the connecting cable is starting to corrode and become a higher
resistance or is broken.
The calibration is a fully automatic action that can be done at any time. To calibrate the
channel, ensure that the electrical connection is secure, and the LED navigation lamp is fully
functional. Then press the calibration button for that channel momentarily. The unit will turn
on the LED, let it stabilise, measure and record the current draw.
Thereafter the unit will check that the current draw is at least 85% of the calibration current
when the LED is on or will indicate a fault by lighting the red Channel LED and indicating the
fault in the PGN messages back from the unit.
When the fault has been rectied then the user can re-calibrate the channel by repeating the
above procedure.
LED Characteristics Meaning
No LED illuminated Channel switched OFF
Green LED Flashing Channel switched ON but NOT calibrated
Solid Green LED Channel calibrated and switched ON
Red LED ashing Channel switched ON but over hours
Solid Red LED Channel LED current < 85% of calibration value failure
2.8 LED POWER ON HOURS
Each channel of the 5971 and the 5972 keeps a track of the LED power on hours which is stored
in non-volatile memory. When any channel exceeds 50,000 hours then the channel will remain
fully functional but the channel indicator LED will ash red.
When the LED navigation lamp has been replaced hold the channel calibration button down for
more than 8 seconds to reset the power on hours back to zero for the new lamp.
2.9 MAINTENANCE
• Clean the unit with a soft cloth. Do not use chemical cleaners.
• Ensure that the unit is mounted securely on the DIN rail
• Ensure any Expansion Units are securely plugged into the Controller/other expansion unit
• Check the security of the NMEA2000® network cable, tighten if necessary.
• Check the security of the power and LED cables connected to the terminal blocks, reseating
them if necessary.

3OPERATION
Ensure that the NMEA2000® network cable is securely attached and that the Device Instance
rotary switches have been set to a valid and unique Device Instance on the network. The
switches are marked with a Hexadecimal notation, so each switch has 16 possible positions. The
combination of the two switches can be set from “00” being Device Instance 0 through to “FC”
being the equivalent of decimal 252 being the highest valid Device Instance address.
Attach 12 or 24 Volt LED Navigation Light power feeds to the Primary and Secondary power
connection block taking care to get the polarity correct. A local green LED will light for each
power feed that is connected.
Connect the LED navigation lights to the terminal blocks taking care to get the polarity correct.
Each output circuit has a 750mA resettable fuse included for protection.
The unit is controlled by issuing PGN 127502 Switch Bank Control messages with the rst byte
of the message matching the Device Instance value. Switch 1 control eld controls channel 0 on
the Controller through to Switch 8 control eld controlling channel 7 on the controller. Switch 9
through Switch 16 control eld operate the next eight channels on an Expansion unit and Switch
17 through 24 operate the next eight channels on the second expansion unit. Switch 25 through
28 control elds do not operate and channel switches.
The unit will transmit PGN 127501 Binary Status Report PGN every 2.5 seconds to advise
navigation LED status including any error conditions. This Binary Status Report PGN rst byte
will contain the Device Instance as set on the rotary switches followed by the status of each
navigation light channel shown as pairs of bits in subsequent bytes with values as follows:
The unit will also transmit a proprietary PGN 131009 upon receipt of an ISO Command PGN
60928 or a Complex Command PGN 126208 requesting PGN131009. This PGN contains detailed
status information, current calibration values and LED total power on hours for each channel.
PGN131009 Contains the following data structure:
Byte 6 = Channel 0 Status
Byte 7 and 8 = Channel 0 LSB and MSB LED Power On Hours
Byte 9 and 10 = Channel 0 LSB and MSB Channel milliwatts
Byte 11 and 12 = Channel 0 LSB and MSB Calibration milliwatts
These are repeated for channels 1 to 23.
Status byte Bit 0 = LED on, Bit 1 = fault, Bit 5 = calibrated, Bit 6 = watts <85% or >115% of
calibration and Bit 7 = LED Hours over 50,000
