2 Safety instructions

• The device described is a subcomponent for integration into a system�

- The manufacturer of the system is responsible for the safety of the system�

- The system manufacturer undertakes to perform a risk assessment and to

create a documentation in accordance with legal and normative requirements

to be provided to the operator and user of the system� This documentation

must contain all necessary information and safety instructions for the operator,

the user and, if applicable, for any service personnel authorised by the

manufacturer of the system�

• Read this document before setting up the product and keep it during the entire

service life�

• The product must be suitable for the corresponding applications and

environmental conditions without any restrictions�

• Only use the product for its intended purpose (→ Functions and features).

• Only use the product for permissible media (→ Technical data).

• If the operating instructions or the technical data are not adhered to, personal

injury and/or damage to property may occur�

• The manufacturer assumes no liability or warranty for any consequences

caused by tampering with the product or incorrect use by the operator�

5

UK

• Installation, electrical connection, set-up, operation and maintenance of the unit

must be carried out by qualified personnel authorised by the machine operator�

• Protect units and cables against damage�

3 Functions and features

The unit monitors industrial oils�

It detects the two process categories volumetric flow and medium temperature�

4 Function

• The unit detects the volumetric flow quantity based on the principle of

differential pressure�

• The device has an IO-Link interface� It provides the following additional

functions using suitable hardware and software:

- Remote parameter setting of the unit�

- Transmission of the set parameter values to other sensors�

- Electronic locking of the sensor via software�

- Simultaneous reading of all process values (volumetric flow and temperature)

and the binary switching signals�

- Extensive display of error and event messages�

- Display of minimum and maximum temperature values�

• The unit displays the current volumetric flow quantity or temperature�

It generates 2 output signals according to the parameter setting:

OUT1/IO-Link: 4 selection options Parameter setting

- Switching signal: limit values for volumetric flow quantity → 9.2.1; → 9.2.2

- Switching signal: limit values for temperature → 9.3.1; → 9.3.2

- Frequency signal for volumetric flow quantity → 9.2.6

- Frequency signal for temperature → 9.3.6

OUT2: 4 selection options Parameter setting

- Switching signal: limit values for volumetric flow quantity → 9.2.3; → 9.2.4

- Switching signal: limit values for temperature → 9.3.3; → 9.3.4

- Analogue signal for volumetric flow quantity → 9.2.5

- Analogue signal for temperature → 9.3.5

4.1 Switching function

OUTx changes its switching status if it is above or below the set switching limits

(flow or temperature)� Hysteresis or window function can be selected� Example of

volumetric flow monitoring:

Hysteresis function Window function

SP

rP FL

FH

SP = set point

rP = reset point

HY = hysteresis

Hno / Fno = NO (normally open)

FH = upper limit value

FL = lower limit value

FE = window

Hnc / Fnc = NC (normally closed)

When the hysteresis function is set, the set point (SP) is defined first and

then the reset point (rP) which must be of a lower value� If only the set point

is changed, the reset point remains constant�

When set to the window function the lower limit value (FL) and the upper

limit value (FH) have a fixed hysteresis of 0�25 % of the final value of the

measuring range� This keeps the switching status of the output stable if the

volumetric flow varies slightly�

4.2 Analogue function

• The unit provides an analogue signal that is proportional to the volumetric flow

quantity and the medium temperature�

• Within the measuring range the analogue signal is 4��20 mA�

• If the measured value is outside the measuring range or in the event of an

internal error, the current signals indicated in Figure 1 and 2 are provided�

4.3 Frequency output

The unit provides a frequency signal that is proportional to the volumetric flow

quantity and the medium temperature�

UK

Up to the limit value set under [FEP1] (for OUT1 = TEMP: between the limit values

set under [FSP1] and [FEP1]) the frequency signal is between 0 Hz and the

frequency value set under [FrP1]�

4.4 Customer-specific calibration (CGA)

The viscosity indicated for the sensor application (→ Technical data) applies to an

oil temperature of 40 °C� For other temperatures the viscosity of the oil used may

deviate from the viscosity of the reference oil used for the calibration of the sensor�

►In this case adapt the calibration factor CGA, see example:

Temperature Viscosity CGA

Reference oil 20 °C 430 mm2/s 100 (factory setting)

Oil 1 20 °C 540 mm2/s 80 %

Oil 2 20 °C 360 mm2/s 120 %

After a change the calibration can be reset to factory setting (→ 9.5.2)�

4.5 IO-Link

This unit has an IO-Link communication interface which enables direct access to

process and diagnostic data� In addition it is possible to set the parameters of the

unit during operation� Operation of the unit via IO-Link interface requires an IO-

Link capable module (IO-Link master)�

With a PC, suitable IO-Link software and an IO-Link adapter cable communication

is possible when the system is not in operation�

For the IODDs necessary for the configuration of the unit, detailed information

about process data structure, diagnostic information, parameter addresses and

the necessary information about the required IO-Link hardware and software visit

www�ifm�com�

4.6 Measured value damping

With measured value damping, a delay time can be set by means of which the unit

provides an erratically occurring flow change� The set damping time stabilises the

outputs, the display and the process value transfer via the IO-Link interface�

Two damping times can be set:

[dAP] = damping time for switching signal, display and IO-Link signal

(63 % rise time)�

[dAA] = damping time for analogue signal (10��90 % rise time)�

11

UK

The damping time is added to the response time of the sensor (→ Technical data).

The signals [UL] and [OL] (→ 12) are defined under consideration of the damping

time�

4.7 Colour change display (coLr)

The colour of the characters in the display can be set via the parameter [coLr]

(→ 9.4.4)� With the set parameters rED (red) and GrEn (green), the display is

permanently set to one colour� If the parameters rxou and Gxou are set, the colour

of the characters changes depending on the process value:

OUT1 OUT2 Colour change to ��
