3. Safety
The ow switch is used for monitoring ow losses and dry run. With analogue signal the ow switch 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.

5.1 Mechanical mounting
Only use the ow switch if it 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.
■
Position the probe tip in the area of maximum ow rate
(pipe centre).
■
The minimum immersion depth of the probe 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.
Risers and vertical pipes
Mounting the ow switch in downpipes open towards the bottom is forbidden. This use does not comply with the intended use.

5.1.3 Probe alignment
During mechanical assembly of the FSD-3, 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 seals see WIKA
data sheet AC 09.08 or at www.wika.com.
5.1.5 Disturbing interferences in the piping system
For correct measurement, the ow switch requires a fully
characterised 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
.
Seal the process connection (→ see “Sealing variants”).
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
Power supply: DC 15 ... 35 V
The power supply for the ow switch must be made via an energy-limited electrical circuit in accordance with section
9.3 of UL/EN/IEC 61010-1 or an LPS to UL/EN/IEC 60950-1 or class 2 in accordance with UL1310/UL1585 (NEC or
CEC). The voltage supply must be suitable for operation above 2,000 m above sea level, should the ow switch be
used at this altitude.
Requirement for shielding and grounding
The ow switch must be shielded and grounded in accordance with the grounding concept of the plant.
The instrument must be grounded via the process connection.
Connecting the instrument
1. Assemble the mating connector.
→ see pin assignment
2
.
Establish the plug connection.

5.3 Operating modes
System start
■
Display is fully activated for 2 seconds.
■
When the ow switch is powered up within the range of the hysteresis, the output switch is set to “not active” by
default.
Display mode
Normal operation, display of ow or temperature value (depending on setting)
Programming mode
Setting the parameters
The in-factory adjustment is carried out with the medium water. It is recommended to carry out the adjustment, relative
to the minimum/maximum ows of the system, via the menu (→ see chapter 5.6 “Adjustment”)
5.4 Keys and functions
The ow switch has two operating modes, the display mode and the programming mode. The selected operating mode
determines the respective function of the key.
Key Function
Jumping into the programming mode
Keep the “MENU” key pressed for approx. 5 seconds. If the password is set to ≠ 0000, a
password will be requested rst.

.
Mount the ow switch and connect it electrically.
(→ refer to 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.

5. Recall menu item “SETF” ▶ “MAX” and conrm “100”.
5.7 Switching functions
Hysteresis function
If the ow rate uctuates around the set point, the hysteresis keeps the
switching status of the outputs stable. With increasing ow rate, the output
switches when reaching the switch point (SP).
■
Contact normally open (HNO): Active
■
Contact normally closed (HNC): Inactive
With the ow rate falling again, the output will not switch back before the
reset point (RP) is reached.
■
Contact normally open (HNO): Inactive
■
Contact normally closed (HNC): Active
