2. Note

Please read these operating instructions before unpacking and putting the unit

into operation. Follow the instructions precisely as described herein.

The instruction manuals on our website www.kobold.com are always for currently

manufactured version of our products. Due to technical changes, the instruction

manuals available online may not always correspond to the product version you

have purchased. If you need an instruction manual that corresponds to the

purchased product version, you can request it from us free of charge by email

([email protected]) in PDF format, specifying the relevant invoice number and

serial number. If you wish, the operating instructions can also be sent to you by

post in paper form against an applicable postage fee.

Operating instructions, data sheet, approvals and further information via the QR

code on the device or via www.kobold.com

The devices are only to be used, maintained and serviced by persons familiar

with these operating instructions and in accordance with local regulations

applying to Health & Safety and prevention of accidents.

When used in machines, the measuring unit should be used only when the

machines fulfil the EC-machine guidelines.

as per PED 2014/68/EU

In acc. with Article 4 Paragraph (3), "Sound Engineering Practice", of the

PED 2014/68/EU no CE mark.

3. Instrument Inspection

Instruments are inspected before shipping and sent out in perfect condition.

Should damage to a device be visible, we recommend a thorough inspection of

the delivery packaging. In case of damage, please inform your parcel service /

forwarding agent immediately, since they are responsible for damages during

transit.

Scope of delivery:

The standard delivery includes:

 Low-Volume Flow Switch model: SVN / KSR

SVN/KSR

Page 4 SVN/KSR K08/0823

4. Regulation Use

Any use of the Flow Switch, model: SVN/KSR, which exceeds the manufacturer’s

specification, may invalidate its warranty. Therefore, any resulting damage is not

the responsibility of the manufacturer. The user assumes all risk for such usage.

5. Operating Principle

The KOBOLD flow switch types SVN and KSR operate on the known suspended

float principle of measurement and are suited for liquids and gases.

This switch must be fitted vertically with the media flowing from bottom to top.

Set point

The flow switch is designed for small flows. The set point is set at the factory to

the value specified by the customer (a decreasing or increasing flow rate is

specified).

6. Mechanical Connection

Before installation:

 Remove all packing materials and transport retainers and ensure that no such

materials remain in the device.

 Make sure that the maximum operating pressure and temperature of the device

are not exceeded (see Fehler! Verweisquelle konnte nicht gefunden

werden. Fehler! Verweisquelle konnte nicht gefunden werden.).

 Install the flow switch in the piping system, ensuring that the piping is rigidly

supported at the inlet and outlet of the switch with pipe clamps

 Ensure that the piping is aligned with the inlet and outlet fittings and the no

piping induced stresses are exerted in the switch. This stress can result in

damage to the switch during system operation

 Protect the measuring tube from external damage.

 Avoid pressure surges in the measuring tube, such as those arising from fast

start up/shut off of flow or pulsating flow.

 If possible, after completing the mechanical installation, check the threaded

connection between the device and the piping for leakage immediately.

For complete information on the proper installation of float-type flow

meters, see VDI/VDE Directive 3513.

7. Electrical Connection

 Make sure that the electrical supply lines are de-energized when connecting

the device!

 Connect the power supply line to the device connection as shown in the

illustration below.

7.1. SVN-1201 (Proximity Switch)

UB = 10 – 30 VDC , 3-wire

Output: NPN, N/O contact

Attention! The electrical values specified for the proximity switch

must not be exceeded.

7.2. KSR with Reed Contact

SPST contact

SPDT contact

COM

Attention! The electrical values specified for the contact must not

be exceeded, even for a short time. For higher switching capacities,

we recommend installation of our contact protection relay (such as

model MSR) or other contact protection measures.

After connection of all necessary external devices to the limit contact, the device

is completely set up and can now be placed in operation.

8. Maintenance

If the medium to be measured is not dirty, SVN/KSR Flow Monitors are

essentially maintenance-free. However, any lime or dirt deposits on the housing

or the internal parts should be removed regularly.

To clean the flow monitor, proceed as follows:

 Make sure that the electrical supply lines are de-energized.

 Unscrew the flow monitor from the line.

 To disassemble the flow monitor, remove the stud screws.

 Clean the flow monitor in a cleaning bath or in an ultrasonic bath.

 When reassembling the flow monitor, be sure that the gaskets are seated

properly.

12. Disposal

Note!

 Avoid environmental damage caused by media-contaminated parts

 Dispose of the device and packaging in an environmentally friendly

manner

 Comply with applicable national and international disposal regulations and

environmental regulations.

Batteries

Batteries containing pollutants are marked with a sign consisting of a crossed-out

garbage can and the chemical symbol (Cd, Hg, Li or Pb) of the heavy metal that

is decisive for the classification as containing pollutants:

Cd1 Hg2 Pb3 Li4

1. „Cd" stands for cadmium

2. „Hg" stands for mercury

3. „Pb" stands for lead

4. „Li" stands for lithium
