Covers HBSO, HBSR, HBSC2, HBLC, HBLT, HBLS and HBX
Introduction
The sensors and switches designed for hazardous areas all use a two-wire connection. This means
the output will be 4-20 mA and the output will normally pass through a barrier before it is
connected to a PLC. For level sensors normally providing an analog output will still be a 4-20 mA
signal linear to the measurement. For level switches the output will be 4 mA representing off and
20 mA representing on.
The sensors and switches can be setup like normal products but when in operation only pin 1 and
4 will be in operation.
Calibration can be done using the HB-tool like normal sensors or the "R" button can be used inside
the hazardous zone where you cannot bring a PC.

- Page 5 LED indication The green LED is flashing and indicates 24 V DC supply. (normal operation mode) The yellow LED (Control) is used for calibrating using the “R” button. The red LED (Alarm) is not used. The red and green LEDs flashing indicate no connection between mechanical and electrical unit. All three LEDs are flashing when the sensor is connected to the HB tool.
