Connections

3.2.1 Power supply
The instrument is suitable for both 12 and 24
Volt direct current.
Connect the power supply as shown in the
wiring diagram, see Chapter 6.
3.2.2 Background lighting
The background lighting can be switched
on and off by an external switch (dashboard
lighting). The function 'Light' must then be
set to 'Automatic' , see 2.4.6 'Setting the back-
ground lighting' .
3.2.3 Alarm outputs
External warnings, such as a light or a buzzer,
can be connected to the alarm outputs.
If these devices use more than 200 mA con-
nect a small relay in between.
3.2.4 Sensors
Fit the sensors in the tanks as described in the
instructions supplied with the sensor.
Each sensor has a cable (about 1.5 m ) with an
RJ45 connector.
Connect the sensors to the display instru-
ment and to each other as shown in the in-
stallation examples, see Chapter 7.
Use a patch cable*) and a double RJ45 cou-
pling piece to extend the cable to the sensor.
2 sensors can be connected directly to the
instrument.
NB: there is no difference between the two
connections!
Use the splitters and connection cables sup-
plied if more than 2 sensors have to be con-
nected.
