– TECHNICAL USER GUIDE
MOUNTING GUIDE
For optimum measurements DOL 53 should be installed at the centre of the area to be monitored. DOL 53 must be installed out of reach of
animals, accessible for maintenance work, suspended from the lug at the end of the housing or alternatively with a mounting bracket on the wall.
DOL 53 must not be mounted near the fresh air supply, in front of windows or doors, large electrical consumers (electromagnetic
influences), in exhaust air ducts, behind air washers or behind screens. DOL 53 must not be mounted in inaccessible areas.
Protect against direct exposure to dust or splash water. For wall mounting, unobstructed gas entry must be ensured.
DOL 53 must be mounted vertically with the sensor pointing down; ±30° at a
location with low vibration and, as far as possible, stable temperatures.
NOTICE
DOL 53 must not be suspended from the electric cable.
INSTALLATION GUIDE
The scope of delivery includes an approx. 2.5-meter-long cable connection
(5)
for
the electrical installation up to the junction box
(1)
. For the electrical supply and
signal transmission to the control unit cables with adequate cross-section must be
used. Connect the cable from the installation kit to the connector
(4)
and in the
junction box
(1)
. Connect the GND cable in the control unit to protective earth.
The cable must be routed in a manner to obtain a "water loop"
(2)
for water to
drop off. Insert the cable into the clamping device
(3)
at the mounting lug. Attach
with a cable tie. Do not stress the cable.
