DFM 8EDM to a fleet manager or
to a GPS system
Before you start
with the electrical connection of the system, you must have done a correct installation of the delive-
red components. This installation must be done by an authorized and certified company/person.
Please be aware: an incorrect installation may destroy the DFM-System and damage your vehicle. In this case, Aqua-
metro will deny all responsibilities.
Function description
• The supply line starts from tank, goes to the pre-filter, to the fuel pump, to the supply-line-flow-meter, to the fine filter and than to the in-
jection pump.
• The injection pump injects the needed amount of fuel and returns the rest over a return line to the tank. Also a so called “leak-line” from
each injection valve are collected to one line and connected over a t-piece to the return line (see Schematic of a configuration).
• The return line ends to the tank.
This is a global description. Deviation from it may occur.
Installation description
The CONTOIL
®
DFM 8EDM has 2 flow chambers: supply line chamber and return line chamber. Those chambers are marked with a “S” for
supply and with a “R” for return. The chamber fuel entry is marked by an arrow (see pictures).
Mount the CONTOIL
®
DFM 8EDM to a vibrations-free place on the vehicle (NOT on the engine!). Connect the supply line chamber in-bet-
ween the fuel supply line. Connect the return line chamber in-between the fuel return line. Tight all the connection.
Electrical connection
The CONTOIL
®
DFM 8EDM has 4 wires:
Wires color
Function
Remark
White
12 - 24 VDC
Input voltage 12 - 24 VDC from the DFM-BC or from another source. If you use another
source, make sure the voltage
is stable and filtered
.
Brown
GND
Ground (take the same ground like the 12 - 24 VDC source).
Green
Open drain (out1)
When a signal is generated, this line will go to ground.
Yellow
Voltage Level (out2)
Below 0.8 VDC = no signal (logic 0)
Between 0.8 - 2.8 VDC is undefined zone
Over 2.8 VDC = signal (logic 1)
Connect the described wires above according to the instruction on the installation manual of the fleet manager or GPS system.
