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.
Calibration instructions:
The sensors can be calibrated by using the HB tool or by using the “R”
button. The 0% or 100%
calibration can be carried out independently of each other. The sensor is delivered pre-calibrated.
For normal use, calibration is not necessary. If the signal changes over time, we recommend a 0%
calibration.
Instruction for 0% calibration/dry calibration:
1)
Make sure the sensor is dry and power supply is connected.
2)
Press the "R" for approx. 20 seconds until the yellow LED turns off.
3)
Activate "R" once = Yellow LED flash once.
"Calibration mode" is complete and the sensor is then running normally.
Instruction for 100% calibration - for level sensor only:
1)
Make sure the sensor is filled with liquid and power supply is connected.
2)
Press the "R" for approx. 20 seconds until the yellow LED turns off.
3)
Activate "R"
twice
= Yellow LED flash
twice
.
"Calibration mode" is complete and the sensor is then running normally.
Calibration using the HB Configuration Tool
Please follow the instructions in the manual for the standard product. The sensor setup will be
simpler with less parameters, but the principle will be the same.
Installation
The sensor is installed like the similar products without ATEX/Ex certification.
NOTE! To be able to change the sensor parameters, you need a
special USB/M12 configuration cable, as well as a configuration tool
installed on a PC, also see safety instruction before using the PC tool.
