3 Functions and features
With this unit angular movements and positions of the valve between 0°...179.9°
and -180°...0° can be determined. The unit generates output signals according to
the operating mode and the parameter setting.
4 Installation
► Disconnect power before installation.
► Ensure that the machine stands still.
► Do not start the drive during installation.
► Keep potential interfering sources (magnets, heat sources) at a distance.
This product complies with the standard EN 61000-6-4. The unit may cause radio
interference in domestic areas. The user must take appropriate measures to avoid
this interference, if necessary.

1: Use the two notches at the bottom of
the target puck as a mounting aid for a
precise positioning on the shaft. Align
target puck. The yellow indicator can
be rotated to show the desired open
position.
Fix the target puck to the valve head
using the supplied screw, tightening
torque 1.2 Nm.
2: Put the unit over the target puck.
3: Fix the unit to the actuator housing
using the supplied screws, tightening
torque 1.5 Nm. Use an optional
mounting plate, depending on the
mechanical interface.

8 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 while it is in operation. Operation of the unit via an IO-Link interface requires
an 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.

6
The IODDs necessary for the unit's configuration, detailed information about
process data structure, diagnostic information, parameter addresses and the
necessary information about required IO-Link hardware and software can be
found at www.ifm.com.
9 Parameter setting
The parameters of the unit can be set both via the inductive teach button and via
IO-Link. To be able to use all the functions of the unit, an IO-Link communication
is required.
9.1 Parameter setting with IO-Link
Using an IO-Link capable parameter setting tool, the following options are
available:
- Reading current process values.
- Reading, changing and saving current parameter settings and transmitting
them to other units of the same type.
► Connect the unit via the IO-Link interface to a PC or PLC with suitable
parameter setting software.
ifm offers an IO-Link interface for the connection of the sensor via USB
port.

9.3 Manual parameter setting
9.3.1 Switch points
The unit has three switch points (SSCs). Two of them can be set via the inductive
teach button, the third switch point can be configured via IO-Link. Tolerance and
hysteresis can be set separately for each switch point, with an additional seal
monitoring for SSC2.
9.3.2 Parameter setting via inductive teach button
The sensor is adjusted using a metal object, e.g. a screwdriver.
Teach switch point 1 (SSC1) - valve open
► Activate teach button until the LED ring flashes yellow. Remove metal tool.
> LED ring yellow on, switch point is set.
Teach switch point 2 (SSC2) - valve closed
► Change valve position manually.
► Activate teach button until the LED ring flashes blue. Remove metal tool.
> LED ring blue on, switch point is set.
Swap switch points SSC1 and SSC2
► Activate teach button until the LED ring flashes yellow / blue. Remove metal
tool.
> LED ring yellow or blue on, switch point has been swapped.

Setting leak warning range
In the closed position SSC2, the unit features
leak monitoring in the range from 0.0° to 15°.
Deposits or wear can be detected. This leak
warning range lies within the tolerance range
and is activated and defined by selecting a
value (>0) which is deduced from the tolerance
range limits.

10.1 Timeout
Timeout indicates the maximum duration for closing or opening before the sensor
signals a blockage.
Adjustable time: between 0.1...30 s (factory setting 30 s).
In parallel, the parameters for the maximum closing and opening duration must be
adjusted manually (timeout ≥ maximum closing / opening duration).
10.2 Colours
For each switching output (SSC) different display colours of the LED ring can be
set individually.
You can choose among the following colours:
blue, green, cyan, red, magenta, yellow and white.
The colour feedback can be deactivated.

10.3 Parameter setting pin 5
Pin 5 of the sensor can have different functions:
1. Switching output valve position open
2. Switching output valve position closed
3. Switching output seat position
4. Fault output
- Defect of the unit
- Puck not used
- Limit value for the timeout exceeded
10.4 Opening / closing duration
The minimum/maximum closing/opening duration of the drive can be freely set
and monitored. The sensor provides a warning via IO-Link if the actual value is
above or below the limit value.
Adjustable time: between 0.1...30 s
(factory setting: minimum opening/closing duration: 0 s; maximum opening/closing
duration: 30 s).
