TECHNICAL USER GUIDE

PRODUCT DESCRIPTION:

DOL 44R is a capacitive relay sensor for
detection of feed, grain and solids. The
sensors have relay output including switch
function.
Fields of application:

• Level control in silos and containers

• Controlling the filling and emptying

process.

MOUNTING GUIDE (FIG. 1):

DOL 44R includes M30 thread. Mount it in a
ø30 mm hole and tighten using the locknuts
included.

DOL 44R is made in a ø30 mm smooth
design mounted in a PG36/M40 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.

USER’S GUIDE (FIG. 3):

Depending on its type, DOL 44R has
two trimmers with different
functionalities.
Delayed disconnection:

• Fixed time or

• Time adjustable on trimmer

Delayed connection:

• Fixed time or

• Time adjustable on trimmer

Sensitivity:

• Fixed distance or

• Distance adjustable on trimmer

Max RunTimer:

• Settings on the trimmer: Off, Period 1,

Period 2
The actual functionality of the sensor is
indicated on the product label.
DOL 44R has a red LED, indicating
sensor status.
Fig. 3 shows examples of LED
sequences.

DOL 44RH has a built-in, controlled heat
function which prevents frost and
condensation on the sensor. This
ensures optimum detection in very cold
and damp environments.
The heat function is only possible for the
90-265 V AC voltage version.
