3.1 Explanation of symbols
WARNING!
... indicates a potentially dangerous situation that can result in serious injury or death, if not avoided.
CAUTION!
... indicates a potentially dangerous situation that can result in light injuries or damage to property or the
environment, if not avoided.
WARNING!
... indicates a potentially dangerous situation that can result in burns, caused by hot surfaces or liquids,
if not avoided.

3. Safety
Information
... points out useful tips, recommendations and information for ecient and trouble-free operation.
3.2 Intended use
The ow switch has been designed and built solely for the intended use described here, and may only be used accordingly.
■
Conversion of ow velocities into an electric signal.
■
No assembly in downpipes open towards the bottom.
■
Use in buildings and outdoors (avoid high ambient temperatures and direct UV irradiation).
■
Environment with max. pollution degree of 3.
■
Voltage supply of overvoltage category II.
The ow switch is used to monitor whether the ow exceeds or drops below specied ow values, e.g. to prevent
pumps from dry running. The analogue signal should only be used as a trend indicator in order to monitor process
changes, such as lter blocking.
Only use the ow switch in applications that lie within its technical performance limits.
→ For performance limits see chapter 9 “Specications”.
Refrain from unauthorised modications to the ow switch.
Any use beyond or dierent to the intended use is considered as improper use.
The manufacturer shall not be liable for claims of any type based on operation contrary to the intended use.
3.3 Personnel qualication
Skilled personnel
Skilled personnel, authorised by the operator, are understood to be personnel who, based on their technical training,
knowledge of measurement and control technology and on their experience and knowledge of country-specic regula-
tions, current standards and directives, are capable of carrying out the work described and independently recognising
potential hazards.
Special operating conditions require further appropriate knowledge, e.g. of aggressive media.

3.4 Use of accessories and spare parts
It is recommended to use original accessories and original spare parts from WIKA. Using accessories and spare parts
from third parties can lead to damage to the instrument or accidents, due to quality defects or other reasons.
WIKA assumes no liability for damage or accidents caused by a malfunction or unsuitability of accessories and spare
parts which do not originate from WIKA (e.g. non-compliance with the IP ingress protection of connectors). No warranty
claims can be made which arise due to a malfunction or unsuitability of any accessory or spare part from a third party.

4.1 Transport
Check the ow switch for any damage that may have been caused by transport.
Obvious damage must be reported immediately.
4.2 Packaging and storage
Do not remove packaging until just before mounting.
Keep the packaging as it will provide optimum protection during transport (e.g.change in installation site, sending for repair).
Permissible conditions at the place of storage:
■
Storage temperature: -20 ... +80 °C [-4 ... +176 °F]
Avoid exposure to the following factors:
■
Direct sunlight or proximity to hot objects
■
Mechanical vibration, mechanical shock (putting it down hard)
■
Soot, vapour, dust and corrosive gases
■
Humid or wet environment
■
Hazardous environments, ammable atmospheres
5. Commissioning, operation
5.1 Mechanical mounting
Only use the ow switch if is in perfect condition with respect to safety. Prior to commissioning, the ow switch must be
subjected to a visual inspection.
Commissioning and operation of the instrument may only be carried out by skilled personnel, see chapter 3.3 “Person-
nel qualication”.

5.1.1 Requirements for mounting point
The mounting position and probe length are extremely important for the quality and reliability of the measuring results.
The mounting point must meet the following conditions:
■
Sealing faces are clean and undamaged.
■
Sucient space for a safe electrical installation.
■
For information on tapped holes and welding sockets, see
Technical information IN 00.14 at www.wika.com.
■
Permissible ambient and medium temperatures remain
within the performance limits. Consider possible restric-
tions on the ambient temperature range caused by mating
connector used.
→ For performance limits, see chapter 9 “Specications”
■
The probe tip must be completely surrounded by medium.
■
If possible, position the probe tip in the area of maximum ow velocity (pipe centre).
■
The minimum immersion depth of the sensor is L ≥16 mm.
■
The probe tip must not touch the opposite wall.
5.1.2 Recommended mounting positions
Horizontal pipes
Only if the pipeline is free from
deposits.
Only if the pipeline is completely lled
with medium.

EN
Risers and vertical pipes
Mounting the ow switch in downpipes open towards the bottom is impermissible. This use does not comply with the
intended use.
5.1.3 Sensor alignment
During mechanical assembly of the FSD-4, make sure
that the installation mark points in the opposite direction
of the ow direction of the medium.
5.1.4 Sealing
For sealing the process connections with parallel
threads, use at gaskets, lens-type sealing rings or WIKA
prole sealings at the sealing face. With a tapered thread
(e.g. NPT thread), sealing is made in the thread using
additional sealing materials, e.g. PTFE tape (EN 837-2).
For further information on sealings

5.1.5 Disturbing interferences in the piping system
For correct measurement, the ow switch requires a fully
developed ow prole. This is why calming sections must
be provided in the pipeline after a pump, a pipe elbow,
installed parts and changes in cross-section.
5.1.6 Mounting the instrument
The max. torque depends on the mounting
point (e.g. material and shape). If you
have any questions, please contact our
application consultant.
For contact details see chapter 1 “General
information” or the back page of the
operating instructions.
If a process connection adapter (optional) is used, rst
screw it into the mounting point by hand and then tighten
it using a torque spanner. Use enclosed sealing.
1. Depressurise the system and switch o the ow.
2
.
Sealing the process connection (→ see chapter 5.1.4 “Sealing”).
3. At the mounting point, screw the ow switch in hand-tight.
4. Tighten with a torque spanner using the spanner ats.
5.2 Electrical mounting
Requirements for voltage supply
Supply voltage: DC 15 ... 35 V
This equipment is intended for operation with low voltages which are separated from the AC 230 V (50 Hz) mains voltage
or voltages greater than AC 50 V or DC 120 V for dry environments. A connection to an SELV circuit is recommended, or
alternatively to circuits with a dierent protective measure in accordance with IEC 60364-4-41 installation standard.

5.6 Adjustment
Should you wish to adjust the ow switch to local ow conditions, the FSD-4 oers two ways to make this adjustment.
5.6.1 Adjustment for all units except %
1. Depressurise the system and switch o the ow.
2. Mount the ow switch and connect it electrically.
→ see chapter 5.1 “Mechanical mounting” and 5.2 “Electrical mounting”
3. Select required ow unit in the “INI” menu under “UNIF”.
4. If there is no ow, select the menu item “0SET” in the “INI” menu, select “YES” and conrm.
5. Set the ow to a known value in the plant.
6. Compare this value with the display and calculate the multiplier for the ow value.
Example: System ow velocity: 2.3 m/s
Display FSD-4: 2.5 m/s
muF = 2.3 / 2.5 = 0.92
5. Commissioning, operation

14399527.01 05/2021 EN/DE/FR/ES
20 WIKA operating instructions ow switch, model FSD-4
EN
Enter this value in the initialisation menu under “mu_F” and conrm.
The multiplier function can also be used without prior zero point adjustment.
5.6.2 Adjustment for ow unit %
1. Depressurise the system and switch o the ow.
2
.
Mount the ow switch and connect it electrically.
→ see chapter 5.1 “Mechanical mounting” and 5.2 “Electrical mounting”
3. Recall menu item “SETF” ▶ “MIN” and conrm “0”.
4. Set the maximum ow in the system.
Observe measuring ranges (→ see chapter 9 “Specications”).
5. Recall menu item “SETF” ▶ “MAX” and conrm “100”
5.7 Switching functions
Hysteresis function
If the ow uctuates around the set point, the hysteresis keeps the switching
status of the outputs stable. With increasing ow velocity, the output switches
when reaching the switch point (SP).
■
Normally open contact (HNO): Active
■
Normally closed contact (HNC): Inactive
With the ow decreasing again, the output will not switch back before the reset
point (RP) is reached.
■
Normally open contact (HNO): Inactive
