1. With the DFM-BC in front of you, open the side-wings of the box and unscrew the 4 screws. Put the upper part of
the DFM-System gently a side. Be CAREFULL. The upper part is connected to the base part with a flat cable.
2. Look at the print on the base. You will see a connector with 14 positions.
To ensure a proper function, this cable
must be
connected directly to the vehicle’s battery. Do not connect it
over the start-key of the vehicle. That means, also with the vehicle’s key in your pocket the DFM-BC must be electri-
cal powered. The consumption of the electrical power is far below 1mA.
3. Connect a two wire cable (0.75 mm
2
) from the vehicle battery, through one of the gland, to the position
13 (Batt. plus) and position 14 (Batt. minus). Tighten the gland-nut very well by hand, until the cable is fixed.
To ensure a proper function, this cable must have a direct connection to the battery. Do not connect it over the
start-key
of
the
vehicle.
4. Take the cable from the Auxiliary and pass it through one of the gland of the DFM-BC. Tighten the gland-nut very
well by hand, until the cable is fixed.
5. Connect the cable according to the table below:
DFM-BC
Fleet-Manager or
positions on the connector
GPS Tracking-System
11 (Signal Output)
to
Signal or Digital/Analog Input
12
(Ground)
to
Ground
For more information see section “Electrical connections and Specifications”
6. After all cables are connected and well in place, put the upper part of the DFM-BC back on the base part and
screw
it
down.
7. Take the DFM-BC. If it is off, press one of the 4 Keys on the front to reactivate it. Go to the menu point <Service>.
Press <OK> and enter the Service-Code. Standard service code is: 1111.
8. Set the Auxiliary (AUX) active.

deactivate
the
<AUX>.
10. Set the Fleet-Manager or the GPS-System input according to the “Output Value” set during the installation of the
flow
meters.
Flow meters to Fuel Counter other than the DFM Board Computer (DFM 8D / 20S / 25S)
1. Go to section <Electrical Connections and Specifications> and install the DFM flow meters according to the
specification of the used Fuel Counter.
2. Go to the section “Startup (commissioning)”
DFM-BC connection to other flow meter(s) other than the DFM flow meter(s).
For differential measurement
Supply Line flow meter
1. Connect the “Signal” cable from the flow meter 1 to the pin 3 of the DFM-BC
2. Connect the “Ground” cable from the flow meter 1 to the pin 2 of the DFM-BC
Return Line flow meter
3. Connect the “Signal” cable from the flow meter 2 to the pin 9 of the DFM-BC
4. Connect the “Ground” cable from the flow meter 2 to the pin 8 of the DFM-BC
For direct measurement
1. Connect the “Signal” cable from the flow meter to the pin 3 of the DFM-BC
2. Connect the “Ground” cable from the flow meter 1 to the pin 2 of the DFM-BC
