Overview: This document provides technical instructions for the SISTO-SK-i LED and SISTO-SK-i LED AS-i actual-position feedback units, designed for use with linear pneumatic valve actuators. It includes procedures for remote and on-site initialization, commissioning, troubleshooting, and maintenance.

Specifications and Procedures:

Electrical and Pneumatic Connections: Ensure proper establishment of connections and verify supply voltage and control pressure.
Remote Initialization: For SISTO-SK-i LED, apply 24 volts to the teach-in input for at least 0.5 seconds. For SISTO-SK-i LED AS-i, activate DO2 via AS-i master for the same duration. The feedback unit will actuate the solenoid valve, reach limit positions, and save them internally.
On-Site Initialization: Use a programming magnet on the cover for at least 2 seconds to start initialization. The unit will switch the internal solenoid valve, reach limit positions, and save them.

Commissioning:

Verify all connections and ensure the feedback unit is properly mounted.
Follow the initialization procedures to prepare the unit for operation.

Reset and Shutdown:

Reset: Hold the programming magnet for 30 seconds to reset to factory settings, indicated by a blue LED.
Shutdown: De-energize the system, secure against restart, and ensure no voltages are present before releasing air supply connections.

Troubleshooting:

LED indicators provide status and fault signals. Common issues include power supply problems, initialization errors, and mechanical blockages.
Refer to the LED color codes and signals for specific troubleshooting steps.

Maintenance:

The unit is designed to be maintenance-free, but regular checks of electrical and pneumatic connections are recommended.
Avoid using water jets or aggressive cleaning agents.

Compliance:

The units comply with the Machinery Directive 2006/42/EC, EMC Directive 2014/30/EU, and RoHS Directive 2011/65/EU.
