2 Functions and features
The rising stem valve sensor IX5030 is a continuous absolute linear measurement
system with a measuring stroke of 80 mm� The sensor is used for position
feedback for rising stem valves� For position detection three programmable switch
points can be freely selected in the measuring range� The position is signalled
visually by 3 LEDs�

The rising stem valve sensor IX5030 can be adapted to different valve
types� The instructions in the chapter Installation are to be observed when
designing the adapters and the fixtures�

The valve spindle to be measured must have the following characteristics:
• Diameter 24 mm (tolerance: ± 0�05 mm), height at least 10 mm
• The end surface must be flat
• Material: stainless steel to DIN 17440, material number 316L / 1�4404

3 Function description
• The sensor measures the upper edge of the valve spindle
• Non-contact and wear-free detection of the valve positions: closed (close),
open (open) and the position for seat lift (seat) during the cleaning process�
• It is also possible to monitor the state of the valve seals instead of the seat lift�
Due to the high resolution of 0�2 mm even slight changes can be detected�
• Easy and time-saving adjustment by "teaching" (reading) the valve positions�
The taught valve positions are automatically assigned certain switching
characteristics of the three outputs, several operating modes are available (see
chapters Programming and Set-up)�
• Monitored stroke (detection zone) 80 mm� The condition "valve spindle outside
detection zone" is indicated�
• After adjustment the unit can be electronically locked to prevent unauthorised
manipulation�

4 Installation
Place the sensor (1) on the valve spindle
(2) until the limit stop in a suitable fixture /
adapter (3)�
Fix the sensor to the 3-hole flange (3) by
means of the included fixing screws (6)�
The sensor (1) must either be integrated into
a valve top or correctly fitted to the actuator
(4) by means of a suitable adapter (3)�
If necessary adapt the length of the valve
spindle to the measuring range�

Ensure a tight and secure fit�

Make sure that no metallic components
are in the immediate vicinity of the
sensor or approach the sensor during
operation (especially no metal rings which
enclose the sensor)! This might affect the
functioning of the sensor�
Fixing elements such as screws, clamps
and similar small metal parts (< 20 x 20 x
30 mm) have no impact on the sensor� For
safe functioning the adapter (3) must be
made of plastic�
A = metallic objects
x = min� 10 mm
y = min� 46�5 mm
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�
Disconnect power before connecting
the unit as follows:

After installation you have to adjust the unit to the valve positions to be detected�
You can carry out the adjustment process in a variable and time-saving way� First
clarify which type of valve you have� The sensor differentiates between two types:
1� Valves with 2 operating positions (closed and open)
2� Valves with 3 operating positions (closed, open and a position inbetween for
the seat lift)
For valves with 2 operating positions the wear of the valve seals is monitored
automatically� This function is not possible for the detection of three operating
positions�
The programming options are shown in the programming overview ( → 7�1) After
entering into the programming mode (Teach mode) the unit first expects the
adjustment of the closed position (close)�
However, you can also start with any other position�
If e�g� the valve is already in the open position (open), just start adjusting this
position� To do so, press the Pos� button 2 x, thus skipping the adjustment of the
closed and the seat position� You can carry out the skipped adjustment steps
afterwards�
Skipping a current programming step is also required for example if you use
valves with only 2 operating positions for which the position of the seat lift is not
available� If the position seat lift is not adjusted ("taught") the unit automatically
passes into an operating mode which monitors the wear of the valve seals (see
also chapter Set-up / operation)�
The unit cannot be taught via the AS-i bus�

7.2 Adjustment of the valve positions of valves with 2
operating positions
Press the Pos� button for at
1
least 2 s�
Put the valve into the
2
closed position and press the
Teach button�
Press the Pos� button once,
3
thus skipping the current
programming step� This is
necessary because your
valve does not have the
position seat lift�
All LEDs flash 2 x simultaneously� The unit is
in the programming mode� Then only the LED
"close" is lit�
The unit is now ready for the adjustment of the
closed position (close)�
The LED "close" goes out and the LED "seat"
lights� The unit has stored the closed position
and is now ready for the adjustment of the
position seat lift (seat)�
The LED "open" lights� The unit is now ready
for the adjustment of the open position�
UK
Put the valve into the open
4
position and press the Teach
button�
Press the Pos� button for at
5
least 5 s� After 5 s the LED
"open" flashes at about 2 Hz�
The LED "open" goes out and the LED "close"
lights again� The unit has now stored all
positions�
After releasing all stored measured values
are checked� If no errors are detected all
LEDs simultaneously flash 2 x� The unit
automatically quits the programming mode
and immediately passes into the operating
mode�
If, however, an error is found during the
check the LED "close" flashes at about 8 Hz�
Acknowledge the error message by pressing
the Pos� button and repeat the adjustment�

7.4 Locking / unlocking
The unit can be locked electronically to prevent unintentional operations�
Press both setting pushbuttons simultaneously for at least 10 s in the operating
mode� After 10 s each LED lights briefly one after the other� Then the unit is locked
or unlocked�
In the locked state operations are ignored�
On delivery: unlocked�
8 Set-up / operation
After installation, wiring and adjustment check whether the unit operates correctly�
If possible, put the valve into all available positions and check whether the unit
switches correctly and whether the operations are correctly indicated by the LEDs�
8.1 Indication by LED for the different operating modes
The sensor has 3 operating modes which the sensor automatically generates
depending on the programming�
• Mode A:
For valves with 2 operating positions� The wear of the valve seals is monitored�
• Mode B:
For valves with 3 operating positions� The position seat lift (seat) is between
the positions closed and open�
• Mode C:
UK
For valves with 3 operating positions� The position seat lift (seat) is outside the
positions closed and open�

• The respective LED at the zones marked in grey lights, at the same time the
output corresponding to this state is closed (switched)� At the zones marked in
white and outside the detection area (zones hatched diagonally) all outputs are
open (not switched)�
• All modes are also possible in inverted form, i�e� the open and closed positions
can be inverted� The sensor detects this automatically, the assignment of the
switching characteristics is carried out automatically�
• The open and closed zones are placed nearly at the limits, i�e� the Teach
positions are at the limit of the zones� The seat zones are placed in the middle,
i�e� symmetrically around the Teach position�
• To monitor the seal the open and closed zones in the mode A are only 1�5
mm� The zones open+seat and close+seat are adjacent� In these zones the
14
Page 15
outputs "open" and "seat" and the outputs "close" and "seat" are switched
simultaneously� This signals wear of the valve seal!!
• In the mode A only 2 valve positions are to be adjusted, the positions closed
and open� The adjustment of the seat lift must not be carried out, please skip
this program step by pressing the Pos� button� The sensor then automatically
generates the mode A�
