2 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�

• The unit conforms to the relevant regulations and EC directives�

• 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�

3 Functions and features

3.1 Applications

The unit monitors the flow in liquid and gaseous media�

3.2 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�

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

the switch point:

- Low switch point = quick reaction with rising flow�

- High switch point = quick reaction with falling flow�

4 Installation

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

• The 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�

• For small flow rates ifm adapter blocks are available�

4.1 Installation location

General



•The sensor tip is to be completely sur-

rounded 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 bot-

tom: 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!

4.2 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 inter-

ference:

4.3 Installation procedure

►Ensure that the system is free of pressure during installation�

►Ensure that no media can leak at the mounting location during installa-

tion�

►Grease the threads of the process connection (1), adapter (2) and nut (3)�

►No grease must be applied to the sensor tip (A)�

►Screw the suitable adapter into the process connection�

►Place the flow monitor onto the adapter and tighten the nut� Tightening torque

25 Nm� Ensure that the unit is correctly oriented�

5 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 according to EN 50178, SELV, PELV�

►Disconnect power�

►Connect the unit as follows:

2 1

L+

core colours of ifm sockets:

1 = BN (brown), 2 = WH (white), 3 = BU (blue), 4 = BK (black)

►Do not connect pin 5�

►For the output circuit take the same protective measures as for the

supply circuit� Insert a miniature fuse according to IEC 60127-2 Sheet 1

(≤5Afastacting).

6 Operating and display elements

1: Operating indicators

•The green LEDs indicate the current flow (LEDs 0 to 9 represent the range of the

monitored flow)�

•A lighting LED indicates the position of the switch point (orange = output closed, red =

output open)�

2, 3: Setting buttons for adjustment and configuration

7 Parameter setting

7.1 Set-up

►Switch on the supply voltage�

> All LEDs light and go out again step by step� During this time the output is

closed�

> The unit is in the operating mode�

7.2 Change the switch point (optional)

A change makes sense in the following cases:

• the flow fluctuates much or pulsates�

• if a faster response time of the unit is requested (low switch point = fast re-

sponse with rising flow, high switch point = fast response with falling flow)�

►Briefly press the pushbutton or �

> All LEDs are off�

►Press the pushbutton or as often as required� Each press of the push-

button shifts the flow by one half LED in the indicated direction�

> As soon as a button is pressed, the LEDs are switched on� The LEDs of the

current process value are flashing�

If no pushbutton is pressed for 2 s, the unit returns to the operating mode

with the newly set value�

7.3 Automatic adjustment (Teach function)

►Press the button for at least 15 s�

> First the LEDs 0 and 9 light green, then they are flashing green�

►Release the button�

> The unit adopts the new value and returns to the operating mode�

> All LEDs left of the switch point light green� The switch point LED lights red�

7.4 Restore the factory setting (reset)

►Press the button for at least 15 s�

> All LEDs first light orange, then they are flashing orange�

►Release the button�

> All settings are reset to the factory setting:

- Switch point: 20 cm/s

- Not locked�

> All LEDs go off for 2 s�

7.5 Lock / unlock the unit

The unit can be locked electronically to prevent unintentional settings�

►Press both setting buttons simultaneously for 10 s in the operating mode�

> The indication goes out, the unit locks or unlocks�

When delivered: not locked�

8 Operation

In case of power failure or interruption of the operating voltage all settings remain�

Operating indicators

Current flow below the display range�

Current flow below the switch point�

Current flow corresponds to the switch point�

Current flow above the switch point�

Current flow above the display range�

Interference indicators

The display goes OFF briefly

(LEDs go off when a button is

pressed)

If the sensor is permanently locked, the active

LEDsgooffbrieflywhenabuttonispressed.(→

7�5)�

After approx� 0�6 seconds the last operating status

is indicated�

All LEDs are flashing red

Automatic adjustment not successful� The switch

point is outside the measuring range�

►Check flow and mounting, if necessary repeat

adjustment(→7.3).

Display OFF

(no LED lights):

Operating voltage too low (< 19 V) or failed�

►Ensure correct voltage supply�
