HBLC-HFC - level transmitter for HFC refrigerant
Functionality:
The HBLC-HFC level transmitter is made to control refrigerant level in refrigeration systems. If the
HBLC-HFC is to be used in a different way, prior approval must be obtained from HB Products.

Mechanical installation
Electrical installation
LED indication and calibration of sensor
Mechanical specifications:
Ambient temperature: -20…+50°C
Liquid temperature: -50…+100°C
Max. pressure: 150 bar
Material, mechanical: AISI304/PTFE
Thread connection: see packaging.
Electrical specifications:
Supply: 24 VDC
Current draw: Max 50 mA
Plug: DIN 0627 – M12/5 pins
Enclosure: IP65
Material, electronics: Nylon 6 (PA).
LED indication:
Green LED indicates 24 V DC supply (blinks during operation)
Yellow LED – in connection with calibration
Red LED indicates ALARM at 100%
Installation guide:
It must be mounted vertically.
HBLC-HFC can be mounted on an overflow pipe or a pipe segment
where flow and turbulence are minimized.
Calibration of sensor:
"R" for factory reset and calibration: Alarm is reset by pressing "R" for
5 seconds.
0% or 100% calibration can be carried out independent of each other.
We recommend only calibrating at 0% if a high degree of accuracy is
desired.
CAUTION! In case of welding work on the unit, the electronic part
must be removed. Welding work can damage the electronics. The
mechanical part of the sensor must not be installed in the pipe socket
during welding.
NOTE! All terminals are protected against improper termination with a
supply voltage up to 40 V. If the supply voltage is greater than 40 V the
electronics will be damaged.
CAUTION! Factory settings do not guarantee safe operation, since the
configuration parameters depend on the type of
compressor/separator.
NOTE! Fault detection on the electronic function can be carried out
without releasing pressure from the system or disassembling the
mechanical part of the sensor.
