5 CONNECTION AND WIRING
5.1 PRESENTATION OF INPUTS AND OUTPUTS
The Smartlog’s inputs and outputs are accessible through the I/O connector to the rear of the unit. The signals are wired to it as follows:

5.2 INPUT OUTPUT CABLE
This cable is used to connect any type of sensor (excluding pre-wired sensors).
Follow the colour code to make your various connections.
For digital inputs, use Brown, Red, Orange and Yellow to connect your information; the green wire is the shared earth for these 4 inputs.
The 2 analogue inputs are powered by the Dark Blue wire (“+” of analogue sensors); the signals have to be connected to the Purple and Grey wires
(“-” of analogue sensors). If the analogue sensors are powered by an external power supply to the Smartlog, the 0V power supply and '-' signals from
analogue sensors must be connected to the 0V of the Smartlog (green wire). The signals are then wired on the Violet and Grey wires (“+” of analogue
sensors).
It should be noted that the connection of one or more digital sensors uses the Grey wire (as well as the White and Black wires), depriving the
Smartlog of the Analogue 2 input.
Finally, the digital output uses the Pink and Sky Blue Sky wires.
IMPORTANT
If your configuration includes a pre-wired or digital sensor, they use the Smartlog inputs that can no longer be
used:
- An overflow sensor uses the ETOR2 (red wire)
- A pressure probe uses the EANA2 (grey wire)
- A level US probe uses the EANA1 (purple wire)
- The power supply of digital sensors uses the EANA2/Power supply-RS485 (grey wire)
