Electrical Connection
The sensor must be wired with a 4-cord cable with an M12 connection plug. Colour codes in the diagram below are related
to the cables delivered by HB. The supply voltage is limited to 24V AC/DC.

Quick Installation Guide for: HBLT-WIRE
Mechanical Installation
The sensor is installed in the standpipe or directly in the
tank. The sensor length is determined by standpipe length
or tank height. Please leave 50 mm space between the let
and the bottom of the pipe. Steel wire and Teflon hose
most be cut to desired length with wire cutters or a bolt
cutter, in the end where the let must be installed. Teflon
hose must be mounted outside on the wire.
Standpipe must be insulated to avoid boiling in the stand
pipe.
To install the HBLT-wire, you must use a 2.5 mm Allen
key, shifting spanner, wire cutter and liquid gasket.
Loosen the electronic part from mechanical part.
Define the sensor length from the standpipe height.
Shorten the wire and Teflon hose to required length.
Teflon hose must be 20 mm shorter than the wire.
Make sure that wire is in bottom of the hole.
Tighten the 2 setscrews to fix the wire.
When sealing the conical thread, you must use liquid
conductive sealant, which creates a ground connection
between the standpipe/tank and the sensor, since the
sensor uses the standpipe/tank as reference. If Teflon is
used, it must only be used on part of the thread so that the
ground connection is established. If you are in doubt
regarding the ground connection, measuring the resistance
between the tank and sensor is recommended. This should
be approx. 0 ohms. For cylindrical thread, an alu sealing
ring is included.
L = Programmable sensor length
L= Wire length + 86 mm
Teflon hose most be 20 mm shorter than wire length.
Insert wire in let part and tighten the 2 setscrews. Turn the
top cover plastic part on the metal part (right-hand
thread).

Configuration with PC and HB-TOOL
The HBLT-Wire sensor should be configured to the actual application. The software program can be downloaded at
www.hbproducts.dk. Programming cable has been included. The actual sensor settings can be displayed by pressing the
“Show current figuration” button.

Configuration from sensor front
In case a PC is not available, the sensor configuration can be carried out by the sensor push bottom of the front.
To enter the configuration parameters please press the “R” button for 10 seconds and then follow the steps in the table.
The yellow LED will flash in 5 seconds and after this it will be off. When it is ON again the programming can start. No
change in 15 sec will interrupt the configuration. In that case please press the “R” button for 10 seconds again.

programmable sensor length = Offset [mm]. E.g. if 100 %
should be at 1400 mm and the sensor length is 1600 mm, the
offset length should be 200 mm.
L-offset: Input offset value here. If measurement
