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�

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�

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�

9  Error messages

LED Fault description Measure
close Flashes at 8 Hz directly after
leaving the programming mode = adjustment error! Taught position values are not within the detection range or positions are not
during adjustment
close Flashes at 8 Hz = target is at the limit or
close Flashes at 8 Hz = fault in the electronics�
during operation
allowed or plausible�
outside the detection range or the target is in non defined zones (white zones, see above diagram) for longer than 20 s�
Contrary to the other error messages this error message cannot be acknowledged or terminated�

► Acknowledge the error
message by pressing the Pos� button and repeat the adjustment�
► Check the position of the
valve�
► Replace the sensor�
