9.5 Fuel Level miniDaqu — Manual
9.4.1 Installation
The power cable, which current shall be measured, must be cut at the place
where sensor is to be installed. On each cable end, a M6 round cable terminal
shall be fitted. Use two M6 screws with self locking nuts to connect the power
cable to sensor fitting hole, so that the current will flow trough sensor in the
arrow direction. Any current that flows in arrow direction produces positive
readings and any reverse current produces negative readings.
Sensor has three wires. Red wire provides power for the sensor operation and
connects to +5 V pin. Black wire provides sensor ground and connects to
GND pin. White wire provides signal and connects to one of E or F channels.
See Figure 26 for proper connection schema.

9.4.2 Configuration
The table 13 shows possible channel settings. Alternatively, El. current 2 can
be also selected for the second current sensor.
9.5 Fuel Level
Up to two fuel level sensors can be connected to Daqu. They shall be con-
nected to E channels, though in some other cases other channels can be also
used. Fuel level sensors are either resistive type or active type. Note that
capacitive sensors are just a special case of active sensors.
