This operating manual is aimed at the target group of trained and qualified specialist technical personnel. This operating manual does not take into account: • Any eventualities or incidents which may occur during installation, operation and maintenance performed by the customer. • Local regulations; the operator must ensure that such regulations are observed by all, including the personnel called in for installation. The operating manual must be kept for the entire life cycle of the equipment. For any queries you may have or in the case of damage, please contact SISTO Armaturen. ■ The actual-position...

■ If the actual-position feedback unit is to be used in a damp environment, steps must be taken to ensure that any liquid that collects drains away from and does not penetrate the housing. ■ The unit must never be cleaned with a water jet and/or aggressive cleaning agents (observe the requirements of the type of enclosure Section 7.2, Page 8/Section 7.4, Page 10). ■ The housing of the actual-position feedback unit must not be subjected to mechanical loads. Connection and pneumatic lines must be routed in such a way that no forces act on the actual-position feedback unit. ■ Protect actual-position...

1. Remove the guide bush and the actual-position feedback unit on the pneumatic valve actuator. 2. Screw the actual-position feedback unit into the tread and hand-tight. With connection thread M18 x 1 in the actuator screw in thread adapter first. 3. To adjust the connections exactly, the actual-position feedback unit can be rotated further in clockwise direction. After adjusting the actual-position feedback unit can be tightened with the help of a wire pin (Section 8.3, Page 13). NOTE The bottom housing section and the adapter can be interlocked. To do this, insert a wire pin (diameter = 1 mm)...

8.4 Mounting on valves from other manufactures On demand SISTO-SK-i LED actual-position feedback unit can also be mounted on valves from other manufactures. It is advisable to clarify the technical details in advance by consulting SISTO Armaturen. DANGER Danger from electrical voltage! The system must be de-energised and safeguarded against restarting and it must be verified that it is de-energised before it is accessed. All applicable accident prevention, health and safety regulations must be observed when working on electrical equipment. Danger to life resulting, damage to equipment or damage...

8.6 Pneumatic installation (only for actual-position feedback unit with solenoid valve) 1. Remove the screw plug. 2. Screw the hose connectors into the respective threaded connections on the actual-position feedback unit. (Hose connections are only included in the scope of delivery when an actual-position feedback unit with pneumatic valve actuator is ordered as a unit.) 3. Ensure that the threaded connections are established properly and are leak-free. Replace the silencer at threaded connection point 3 with a hose connector if the exhaust air is to be discharged via a connection line.

9.1 Commissioning the actual-position feedback unit SISTO-SK-i LED/SISTO-SK-i LED AS-i without an integrated solenoid valve - on site 1. Verify that the electrical connections were established properly. 2. Check the supply voltage. 3. The valve actuator must be in its fail-safe position. 4. Check that the actual-position feedback unit is properly mounted on the valve actuator. Start initialisation: 1. Keep the programming magnet in the middle of the top of the cover for at least 2 seconds. If the colour code start flashing yellow, remove the magnet. 2. Activate the external solenoid valve to...

1. Verify that the electrical and pneumatic connections were established properly. 2. Check the supply voltage and the control pressure present. 3. Check that the actual-position feedback unit is properly mounted on the valve actuator. Start initialisation: 1. Keep the programming magnet in the middle of the top of the cover for at least 2 seconds. If the colour code start flashing yellow, remove the magnet again. 2. The Actual-position feedback unit switches the internal solenoid valve, reaches the both limit positions and saves them internally. 3. Limit position will be saved and signalled...
