FUEL TRANSFER CONTROLLER
Part Number: 3350-FTC Fuel Transfer Controller
INSTALLATION AND OPERATING INSTRUCTIONS
The 3350-FTC Fuel Transfer Controller is designed to display the contents of the “Day” or “Consumption” Fuel
Tank and control the pumping of fuel from the storage or “Bunker” tanks into that tank.
The 3350-FTC is housed in a standard 2” / 52mm diameter panel gauge instrument that contains a blue LED digital
display, front panel “START” and “STOP” buttons and a 10 Amp changeover relay to control the Fuel Transfer
Pump.
It has a standard NMEA2000® micro sized male plug to link to the NMEA2000® network and 3 x ¼” male spade
terminals to link to the transfer pump wiring.
SAFETY WARNING
This instrument should only be installed by a person competent and experienced in working on electrical systems
on boats.
BEFORE BEGINNING WORK THE BATTERY SHOULD BE DISCONNECTED TO AVOID THE RISK OF A SHORT CIRCUIT,
A FIRE OR AN EXPLOSION.
Before drilling any holes to mount the unit or to run the cabling always make sure it is safe to do so.
The 3350-FTC Fuel Transfer Controller displays the “Day” or “Consumption” tank level as a % level and so it should
be situated within sight of the helm position.
If there are multiple helm positions then multiple instruments can be installed. In this event the pump control
wiring can be connected in parallel so that either instrument can control the filling of the Day tank.
The instrument is designed to be panel mounted in a 2” or 52mm clearance hole and requires clearance of at
least 100mm behind the hole to allow for cable connections to be run without undue stress.
It is fixed to the panel by using a reversible rear mounting ring nut which can accommodate panels of up to 25mm
thick. The front of the instrument is sealed to IP67 and when correctly mounted in a panel using the supplied
gasket will provide an IP67 seal to the panel.
A mounting hole providing clearance for a 2” / 52mm diameter should be cut at the desired location. The
instrument should be inserted from the front with it’s gasket. The mounting ring nut is attached at the rear and
tightened sufficiently to hold the instrument securely.
THE UNIT ADDRESS SWITCH ON THE BACK OF THE INSTRUMENT MUST BE SET TO EXACTLY MATCH THE UNIT
ADDRESS SWITCH ON THE “DAY” OR “CONSUMPTION” TANK LEVEL SENDER. IF THIS IS NOT DONE THEN THE UNIT
CANNOT STOP A TRANSFER AND A FUEL SPILL COULD HAPPEN.
WIRING AND NETWORK
The male NMEA2000® micro plug should be attached to a Tee connector on the NMEA2000® network either
directly or by using a NMEA2000® micro drop cable.
The wiring to the transfer pump should be as follows:
The power control cables on the back of the 3350-FTC should be connected to the “C” and “NO” terminals.

MANUAL OPERATION
When the user wants to refill the “Day” or “Consumption” tank he simply presses the green START button which
will cause the relay to start the fuel transfer pump if the level in the Day Tank is less than 95%.
The user can stop the transfer at any time by pressing the red STOP button.
AUTOMATIC OPERATION
The unit can be set to automatically start the Fuel transfer if the level in the Day tank falls below a user settable
value. This feature can be enabled by the user setting the automatic start level to 0% through to 70% at 10%
intervals.
This is done by pressing and holding the STOP button and pressing the START button until the display shows the
required start level percentage. If the value is set to 0% then the automatic start feature will remain disabled and
not be functional.
DURING FUEL TRANSFER
Whilst the fuel is transferring the red LED will flash to indicate that a Fuel transfer is in progress.
As soon as the tank level has reached 95% then the relay will stop the transfer automatically.
Please note that the user can stop the transfer at any time by pressing the red STOP button.
If the ship’s power is removed during fuel transfer the transfer will stop. For safety reasons when the power is
restored the unit will NOT restart the transfer unless the START button is depressed again or the automatic start
feature is enabled and the tank level is below the user settable threshold.
CLEANING
The 3350-FTC instrument can be cleaned with mild soap and water. Do NOT use solvents or abrasive or pressure
washers as these could damage the front of the instrument.
