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�

8

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

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

1Press the Pos� button for at

least 2 s�

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)�

2Put the valve into the

closed position and press the

Teach button�

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)�

3Press the Pos� button once,

thus skipping the current

programming step� This is

necessary because your

valve does not have the

position seat lift�

The LED "open" lights� The unit is now ready

for the adjustment of the open position�

4Put the valve into the open

position and press the Teach

button�

The LED "open" goes out and the LED "close"

lights again� The unit has now stored all

positions�

5Press the Pos� button for at

least 5 s� After 5 s the LED

"open" flashes at about 2 Hz�

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

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:

For valves with 3 operating positions� The position seat lift (seat) is outside the

positions closed and open�

LED "close" flashes at 8 Hz�

= valve spindle at the limit or outside the detection range

• 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

Pos [mm]

15

UK

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�
