TECHNICAL USER GUIDE
PRODUCT DESCRIPTION:
DOL 46R is a capacitive relay sensor for
detection of feed, grain and solids. The
sensors have relay output including switch
function. Certified according to ATEX
directive 2014/34/EU and IECEx for
operation in potential explosive dust
atmospheres. Classified as high-level
equipment for use in atmospheres with
continuous presence of explosive dust with
an ignition temperature above 85 °C.
Fields of application:
• Level control in silos and containers
• Controlling the filling and emptying
process.
MOUNTING GUIDE (FIG. 1):
DOL 46R is made in a ø30 mm smooth
design mounted in a gland.

INSTALLATION GUIDE (FIG. 2):
Supply voltage is connected to the blue and
brown wire.
The load is connected in series with the
relay contact of the sensor.
STOP
by activating the sensor: Use the
black wires 1 and 3.
START
by activating the sensor: Use the
black wires 1 and 4.
NOTE!
The internal relay is in position NC
when the supply voltage is connected and
the sensor is activated - wire 1 and 4 are
connected.
