Removing the indicator ring
1. Turn the indicator ring until the bottom edge of the indicator ring and the bottom
edge of the plastic cap are flush.
2. Pivot the indicator ring around 90° (see Fig. 7).
3. You can now remove the indicator ring from the cover of the sensor box.

Assembling the sections
Caution
If handled improperly, the clips on the position indicator sections could break
off.
• Take care to clip the sections together without breaking off the fastening
clips.
1. Clip the sections of the visual position indicator together in such a way that the
open paths of the valve are displayed.

Be sure to make the centre piece (position pointer) and the indicator ring each
from sections of the same colour. One section is included separately.

Mounting the position indicator
1. Insert the indicator ring back into the sensor box cover, by reversing the steps
for removal ( also Fig. 7).
2. Push the centre piece (position pointer) of the position indicator back onto the
shaft of the sensor box. Make sure the alignment is correct.
Before you put the cover of the sensor box back in place, you must carry out elec-
trical installation and commissioning (

7.3 Electrical installation

Warning
Use only power units which guarantee reliable electrical isolation of the opera-
ting voltage as per IEC/DIN EN 60204-1. Observe also the general requirements
for PELV power circuits as per IEC/DIN EN 60204-1.
Caution
Installation errors can damage the electronics or cause faults.
– Use an electrical connecting cable with a nominal outside diameter of
5 to 13 mm.
– Make sure that the length of the signal cable does not exceed the permissible
length of 30 m.
– Connect the earth connection (
with large cross-sectional area) to the earth potential.

Caution
The sensor box contains electrostatically sensitive devices. The internal elec-
tronic components may be damaged if they are not handled correctly.
• Observe the handling specifications for electrostatically sensitive devices.
• Discharge yourself electrostatically before fitting or removing components in
order to protect the components against discharges of static electricity.
The electrical connection terminals are built into the device. For electrical in-
stallation you must open the device and remove the terminal strip. To remove it,
see the steps in section 7.1.
1. If not already done, open the cover and release the terminal strip, as described
in section 7.1.
2. Route the electric cable through the cable connector.
3. Use wire end sleeves suitable for the connection and wire the terminal strip
according to the pin allocation – cable cross section max. 2.5 mm²; torque
max. 0.6 Nm.

4. Connect the earth connection (
with large cross-sectional area) to the earth potential.
5. Carefully plug the terminal strip onto the pin strip. Make sure that release levers
engage properly.
6. Tighten the union nut on the cable connector – torque 2,7 Nm. This ensures the
right tensile load capacity and IP protection class.
