HB Products HBLT-WIRE Quick Installation Manual

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.
Supply 24 V AC/DC
1 = Brown +
2 = White -
3 = Blue – DO, Alarm, PNP/NPN, 1A
4 = Black – AO, Control output, 4-20 mA
5 = Grey – Data communication

LED Indication

LED indication:
1) Green LED indicates 24 V AC/DC power supply
2) Red LED indicates ALARM at 100 %
LED signal ON/OFF/Frequency Functionality
Green ON Power supply
OFF No power supply
Red ON Alarm to be activated at 100% level. The liquid level has to drop
below hysteresis
OFF No alarm

Quick Installation Guide for: HBLT-WIRE

Mechanical Installation

To install the HBLT-wire, you must use a 2.5 mm Allen
key, shifting spanner, wire cutter and liquid gasket.
Define the sensor length from the standpipe height.
Shorten the wire and Teflon hose to required length.
Make sure that wire is in bottom of the hole.

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.
Loosen the electronic part from mechanical part.
Teflon hose must be 20 mm shorter than the wire.
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).
