Third-party valves with strokes between 12...40 mm can be motorized, provided they are «closed with the de-energized» fail-safe mechanism and provided that the necessary mechanical coupling is available. For SKC32.. and SKC82.. actuators the Y1 signal must be routed via an additional freely-adjustable end switch (ASC9.3) to limit the stroke. We recommend that you contact your local Siemens office for the necessary information. Overview table, see page 17.

The valve stem (11) retracts and the valve opens. Simultaneously the return spring (4) is compressed. Activating the solenoid valve (5) allows the oil in the pressure chamber to flow back into the suction chamber. The compressed return spring moves the pressure cylinder upwards. The valve stem extends and the valve closes Turning the manual adjuster (1) clockwise moves the pressure cylinder downwards and opens the valve. Simultaneously the return spring is compressed. In the manual operation mode the control signals Y and Z can further open the valve but cannot move to the «0%» stroke position of the valve. To retain the manually set position, switch off the power supply or disconnect the control signals Y and Z. The red indicator marked «MAN» is visible. When setting the controller for a longer time period to manual operation, we recommend adjusting the actuator with the manual adjuster to the desired position. This guarantees that the actuator remains in this position for that time period. Attention: Do not forget to switch back to automatic operation after the controller is set back to automatic control. Turn the manual adjuster counterclockwise to the end stop. The pressure cylinder moves upward to the «0%» stroke position of the valve. The red indicator marked «MAN» is no longer visible. The actuator can manually be adjusted to a stroke position > 0 % allowing its use in applications requiring constantly a minimal volumetric flow. The SKC32.61, SKC82.61.. and SKC62.. actuators, which feature a spring-return function, incorporate an additional solenoid valve which opens if the control signal or power fails. The return spring causes the actuator to move to the «0 %» stroke position and closes the valve. Control devices TÜV tested per DIN EN 14597 can be used as control devices with safety shut-off function for protection against excessive temperature and pressure: Water: MK..5.., PN 25, see data sheet N4387 Steam: MK..5..G, PN 25, see data sheet N4389 Water, steam, brine, heat transfer oil: MK..6.., PN 40, see data sheet N4388 The valve is controlled by a 3-position signal either via terminals Y1 or Y2 and generates the desired stroke by means of above described principle of operation. · Voltage on Y1 · Voltage on Y2 · No voltage on Y1 and Y2 piston extends valve opens piston retracts valve closes piston / valve stem remain in the respective position The valve is either controlled via terminal Y or override control Z. The positioning signal Y generates the desired stroke by means of above described principle of operation. · Signal Y increasing: · Signal Y decreasing: · Signal Y constant: · Override control Z piston extends valve opens piston retracts valve closes piston / valve stem remain in the respective position see description of override control input, page 8 A frost protection thermostat can be connected to the SKC6.. actuator. The added signals from the QAF21.. and QAF61.. require the use of SKC62UA actuators.

Conduct the electrical connections in accordance with local regulations on electrical installations as well as the internal or connection diagrams. Safety regulations and restrictions designed to ensure the safety of people and property must be observed at all times! For media below 0 °C the ASZ6.5 stem heater is required to keep the valve from freezing. For safety reasons the stem heater is designed for an operating voltage of AC 24 V / 30 W. For this case, do not insulate the actuator bracket and the valve stem, as air circulation must be ensured. Do not touch the hot parts without prior protective measures to avoid burns. Non-observance of the above may result in accidents and fires! Recommendation: Above 140 °C insulating the valves is strictly recommended. Observe admissible temperatures, refer to «Use» on page 1 and «Technical data» on page 12 If an auxiliary switch is required, its switching point should be indicated on the plant schematic. Every actuator must be driven by a dedicated controller (refer to «Connection diagrams», page 15).

When servicing the actuator: · Switch off pump of the hydronic loop · Interrupt the power supply to the actuator · Close the main shutoff valves in the system · Release pressure in the pipes and allow them to cool down completely · If necessary, disconnect electrical connections from the terminals · The actuator must be correctly fitted to the valve before recommissioning. Recommendation SKC6..: trigger stroke calibration. «Replacement parts», see page 17. A damaged housing or cover represents an injury risk · NEVER uninstall an actuator from the valve · Uninstall the valve-actuator combination (actuating device) as a complete device · Use only properly trained technicians to uninstall the unit · Send the actuating device together with an error report to your local Siemens representative for analysis and disposal · Properly mount the new actuating device (valve and actuator) Parts could fly ultimately resulting in injuries from uninstalling an actuator with a damaged valve housing due to the tensioned return spring. The device contains electrical and electronic components and must not be disposed of together with domestic waste. This applies in particular to the PCB. Legislation may demand special handling of certain components, or it may be sensible from an ecological point of view. Current local legislation must be observed. The technical data relating to specific applications are valid only in conjunction with the valves listed in this Data Sheet under «Equipment combinations», page 3. The use of the actuators in conjunction with third-party valves invalidates all claims under Siemens Switzerland Ltd warranty.
