When several sensors type LK or type LK and type LI are mounted in a
vessel the following distance must be adhered to:
min. 45 mm between the probes.
For safe and easy mounting use the ifm mounting accessories (Order
no. E43000 - E43007).
NOTE: Maximum vessel pressure when mounted with mounting
accessories: 0.5 bar.
An overpressure of 3 bar is possible for a short time (max. 1 min.).
The unit must only be connected by an electrician.
The national and international regulations for the installation of elec-
trical equipment must be observed.
Voltage supply to EN50178, SELV, PELV.
Disconnect power before connecting the unit.:

Core colours of ifm sockets:
1 = BN (brown), 2 = WH (white), 3 = BU (blue), 4 = BK (black).
Programming of complementary outputs:
output 1: = Hno, output 2: = Hnc,
SP1 = SP2 / rP1 = rP2.
For safe function the sensor housing must be electrically connected to
the vessel wall.
To do so, use the housing connection with the blue cable lug (see scale
drawing) and a cable piece with a wire cross-section of min. 1.5 mm²
that is as short as possible.
When using metal tanks the electrical ground of the tank serves as the
machine earth. When using plastic tanks an electrode has to be
installed that is connected to the machine earth (e.g. sheet metal in
the tank in parallel with the probe; min. distance to the probe: 40 mm.
