Product Description; Technical Data - DOL 44R-33 Technische Bedienungsanleitung

EN – 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.
In contrast to the standard version DOL 44R-
33, DOL 44RH-33 has a controllable heating
element built in. This prevents condensation in
cold environments.
Fields of application:
• Level control in silos and containers
• Controlling the filling and emptying process.
MOUNTING GUIDE (FIG. 1):
DOL 44R-33 includes M30 thread.
It should be installed so as to leave at least 10
mm from the sensor's end free, ideally using a
PG36/M40 screwed flange.

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.
