Example:>LED9lights.

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 un-

wanted effects in your application�

• That is why installation, electrical connection, set-up, operation and mainte-

nance of the unit must only be carried out by qualified personnel authorised by

the machine operator�

ForthescopeofvaliditycULus:

The device shall be supplied from an isolating transformer having a secondary

Listed fuse rated as noted in the following table�

2 Functions and features

2.1 Application area

The unit monitors the flow of liquid and gaseous media�

2.2 Operating principle flow monitoring

• The unit detects the flow speed to the calorimetric measuring principle and

switchestheoutput:

- output closed if medium is flowing / output open if no medium is flowing�

Thisappliestotheunitondelivery:output=normallyopen.Incaseofneedyou

canchangetheoutputtonormallyclosed(→7.2).Itthenapplies:outputopen

if medium is flowing�

• If the flow speed increases, the switching status changes when the switch point

is reached�

• If the flow speed falls again, the switching status changes if the value "SP

minus hysteresis" is reached�

The hysteresis changes with the flow speed and it is essentially influenced by

the set monitoring range�

Itis2...5cm/sforthesetting5...100cm/s(=factorysetting),itincreaseswith

higher flow speeds�

• The typical response time of the unit is 1��10 s� It can be influenced by the

settingoftheswitchpoint:

- Lowswitchpoint=quickreactionwithrisingflow.

- Highswitchpoint=quickreactionwithfallingflow.

3 Installation

Using process adapters the unit can be adapted to different process connections�

• Adapters have to be ordered separately as accessories�

A correct fit of the unit and ingress resistance of the connection are only

ensuredusingifmadapters.Mountingoftheadapter→3.3.

3.1 Installation location

General



•The sensor tip is to be completely

surrounded by the medium�

•Insertiondepthofthesensor:

minimum 12 mm�

Recommended

•Forhorizontalpipes:mountingfrom

the side�

•Forverticalpipes:mountinginthe

rising pipe�

Conditional

•Horizontal pipe /mounting from

thebottom:ifthepipeisfreefrom

build-up�

•Horizontal pipe /mounting from the

top:ifthepipeiscompletelyfilled

with medium�

To avoid

•The sensor tip must not be in

contact with the pipe wall�

•Donotmountindownpipesthatare

open at the bottom!

3.2 Sources of interference in the pipe system

Components integrated in the pipes, bends, valves, reductions, etc� lead to turbu-

lence of the medium� This affects the function of the unit�

Recommendation:Adheretothedistancesbetweensensorandsourcesof

interference:

► Mounttheadapter(D)ontheunit(A).

►Fix the unit + adapter to the process connection by means of a coupling nut, a

clamp flange or the like (B)�

Ifitisnotpossibletoslidethefixingelement(B)downoverthetopoftheunit:

Slide it up over the bottom of the sensor before the adapter is mounted�

Mounting the adapter

►Slightly grease the threads and sealing areas of the sensor and adapter with

lubricating paste�

The paste must be suitable and approved for the application and compatible

with the elastomers used�

Recommendation:KlüberpasteUH184-201withUSDA-H1approvalforthe

food industry�

►Make sure that the O-ring (C) is correctly positioned�

►Screw the unit into the adapter until it is hand-tight� Avoid mechanical influence

on the sealing areas�

►Clamp unit and adapter into a clamping device (E)� The sealing areas (F) must

not be damaged�

►Tighten the unit slightly using a spanner until you can feel the end stop (this

correspondstoamaximumtighteningtorqueof25Nm).NOTE:Furthertight-

ening may affect the sealing effect

NOTE:Aguaranteeforlong-termstableandmaintenance-freefittingwithnobug

traps in the hygienic sealing of the metal seal (Aseptoflex connection) is only valid

for once-only mounting�

Mounting by means of a welding adapter

►Weld adapter in the pipe or the tank�

►After the unit has cooled down insert and tighten it� Follow the instructions

included with the adapter�

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:

7 Additional settings (optional)

7.1 Low flow adjustment

If the unit is used in media other than water, you should additionally adapt the unit

to the minimum flow�

Note:Thefollowingadjustmentmustonlybecarriedoutafterthehighflowadjust-

ment�

►Let the minimum flow circulate in the installation or ensure flow standstill�

operating mode�

7.2 Configure the switching output

The unit is delivered as normally open� In case of need you can change the output

tonormallyclosed:

►Press the pushbutton for at least 15 s�

> LED0lights,afterapprox.5sitflashes.
