Installation ...
For sensor installation observe the following safety instructions:
– The installation must be carried out only by expert personnel and in accordance
with all applicable safety regulations. This also applies to any local safety and
accident prevention regulations which are not stated in this user guide.
– The sensors are suitable for installation in Ex Zone 0. Observe all applicable rules
and regulations for potentially explosive atmospheres (VDE in Germany respec-
tively national installation rules and regulations).
– For installing, the sensors must be disconnected from power supply.

... of the interface sensor SEPARIX-C L Plus
To avoid the risk of electrostatic charge, the sensors are not permitted to be
used in heavy-flowing, non-conducting fluids (e.g. in pipework or stirred
tanks). The SEPARIX-C L Plus is not permitted to be used in aggressive media.
The interface sensor (4) is suspended on its cable (7) in the light liquid separator (3), im-
mersed into the fluid to be monitored and in a distance of minimum 100 mm to the
separator wall and all separator internal installations (see
not to install the sensor directly near the separator's inlet because of an increased risk of
contamination or disturbance by splashing fluids. The correct fastening method and mate-
rials depend on local installation rules and regulations and the material used for the
separator (concrete, plastic, metal, etc.).
The interface sensor must be installed in such a way that the switch point (5) is undercut at
the maximum permissible layer thickness (6). For example, if a light liquid layer of 300 mm
or more is to be detected, the switch point of the sensor must be 300 mm below the sur-
face of the fluid.
As an adjustment aid, the connection cable can be marked at the appropriate height, e.g.
with a cable tie:
(1)
From the sensor tip, measure 40 mm (switch point) plus the layer thickness and
fasten the cable tie to the connection cable as a marking (for example above:
40 mm + 300 mm = 340 mm above the sensor tip).
(2)
Install the interface sensor so that the marking is at the level of the liquid surface.
