1 Safety instructions
• Please read the product description prior to set-up of the unit. Ensure that the
product is suitable for your application without any restrictions.
• Improper or non-intended use may lead to malfunctions of the unit or to
unwanted effects in your application. That is why installation, electrical con-
nection, set-up, operation and maintenance of the unit must be carried out by
qualified personnel authorised by the plant operator.
• Check the compatibility of the product materials (see technical data) with the
media to be monitored in all applications.
• The device shall be supplied from an isolating transformer having a secondary
Listed fuse rated either
a) max 5 amps for voltages 0~20 V (0~28.3 Vpeak), or
b) 100/Vp for voltages of 20~30 V (28.3~42.4 Vpeak).
• Flow Operated Switches shall be connected only by using any R/C (CYJV2)
cord, having suitable ratings.

2 Functions and features
The unit monitors liquid media (water, glycol solutions, oils).
It detects the volumetric flow quantity to the principle of differential pressure and
switches the output:
• Output closed (LED = ON), if volumetric flow quantity ≥ switch point.
• Output open (LED = OFF), if volumetric flow quantity < switch point.
The switch point is adjustable.
3 Installation
► Ensure that the system is free of pressure during installation.
► Ensure that no media can leak at the mounting location during installa-
tion.
► Install the unit according to the marked flow direction into a pipe RP 1½ and
tighten firmly.

4 Electrical connection
The unit must be connected by a qualified electrician.
The national and international regulations for the installation of electrical
equipment must be adhered to.
Voltage supply to EN 50178, SELV, PELV.
► Disconnect power.
► Connect the unit as follows:
For information about available sockets/connectors see:

5 Switch point setting
There are 2 possibilities:
• Definition of requested value → 5.1.
• Adjustment to existing flow → 5.2.

A: LED; B: setting screw; C: lock screw; D: setting scale
Do not turn the setting screw beyond the maximum value of the setting
range (→ Technical data) to avoid faulty switching.

5.1 Definition of requested value
► Loosen the lock screw.
► Turn the setting screw until the requested value just becomes visible on the
setting scale. → Example in figure 2: requested value = 100 l/min.
► Tighten the lock screw.
5.2 Adjustment to existing flow
► Let the normal flow circulate in the installation.
► Loosen the lock screw.
► Set the switch point with the setting screw.
- If the LED lights before setting: turn the setting screw in the direction [+] until
the LED goes out. Then turn in the opposite direction [-] until the LED lights.
- If the LED does not light before setting: turn the setting screw in the direction
[-] until the LED lights.
► Tighten the lock screw.
Correlation between number of the turns of the setting screw (SET) and switch
point in l/min:
One complete turn corresponds to approx. 18 l/min

6 Operation
After power on the unit is ready for operation. It detects the volumetric flow quan-
tity and switches the output according to the setting.

7 Maintenance, repair and disposal
In case of correct use no maintenance and repair measures are necessary.
In case of strongly polluted media: mount a filter in front of the inlet (IN). Recom-
mendation: use a 50-micron filter.
Only the manufacturer is allowed to repair the unit.
After use dispose of the unit in an environmentally friendly way in accordance with
the applicable national regulations.
