Quick guide
All liquid switches with large electronic unit HBSC2-SSR, HBSR-SSR & HBSO-SSR
Functionality and labelling:
The switches are used for detecting liquid in gas or air. The mechanical elements
are different and optimized to different liquids. The switches use the capacitive
measuring principle and react on the difference in dielectric constant between
liquid and gas
The switches have different calibration and parameter settings in the electronic
unit. The basic electronic unit exist in two versions 24 V and 90-240 V, and it must
match the mechanical part.
The switches are delivered as NO/NC. The switch setting is printed on the small
silver label on the switch together with the type code. On the same label you find
a combined version number and manufacturing date and in second row a unique
production number
Version: VU10 date: 080319 DDMMYY
Production no. 40000

LED indication
3 x green LED´s indicate liquid detection
Yellow LED “RELAY”indicates closed contact
between pin 3 and pin4
Green LED “POWER”indicate power is connected
and switch is active when flashing
Irrespective of the output function NO/NC, the
three LEDs are activated when liquid is detected.
Mechanical installation
The switch is installed in a vessel or compressor,
using Teflon tape or liquid sealant, for those with
NPT thread.
When installing the switch in cold conditions,
where the liquid has high viscosity, make sure
liquid can drain from the switch. This can be done
by sloping the switch 5 degrees downwards.
Long weld adapters should be avoided because
gas pockets can build up and disturb the
measurement
Switches pointing upwards can collect liquid which disturb the measurement
Mounting the electronic unit
The electronic unit is mounted with either a threaded union or with two set
screws in a V-track. The threaded union is mainly used for switches operating in
cold conditions. The set screws are tightened with a torque of 5 Nm and the
threaded union is tightened firmly by hand or by using pliers to secure a good
electrical connection.
Electrical connection
The switch exists in two versions one supplied with 24V AC/DC and one with 90-
240V AC. The switch is delivered as NO (normally open) or NC (normally closed)
and this refers to the contact in the switch in dry conditions. The 24 V version
switch can be changed between NO and NC –this is described in the full manual.
The switch is connected to the power source on pin1 and pin 2. The contact is
potential free relay and it is connected to pin 3 and pin 4
