Electrical Connection - Rechner Sensors i-Level+ Notice D'utilisation

Mounting
It is mandatory to have a galvanic connection between the sensor head and an earthed container (or ad-
ditional electrode)! With metal containers the function earth (BE-conncetion) is normally made through the
threading of the sensor to the metal container. With non-metal containers the connection to the potential
earth is made by means of a cable via an M3 threaded hole at the rear of the sensor.

Electrical Connection

Attention:
For inductive loads, a corresponding protective circuit (e.g. freewheeling diode) must be provided.

IB1 = Non-active range 1
M = Measuring range
IBS =Non-active range shield
The measuring range must not be mounted in the area of the container
where there is a change in the cross section; for example the cone.
The probe can be mounted in the centre of the container or just off
to one side. For a measurement to be independent of the filling cone,
we recommend that the probe be mounted at ¼ of the diameter. The
minimum distance between the end of the measuring range and the
container's lid is 50 mm.
Connect the BE (function earth) by means of the rear screw connection.
Electrical connection:
• Disconnect the system from all power
• Connect the probe according to the connection diagram
• Switch power on
• The sensor automatically detects during starting for each
switching output individually, if the switching output is con-
nected to a "-" (=PNP) or "+" (=NPN) load.
Load resistor is ≤ 20 k Ohm for the digital outputs S MIN
and S MAX.
