Note
Third-party valves with strokes between 6 and 20 mm (SKB...) and 12 ... 40 mm (SKC...) can be motorized, provided they have a «closed when de-energized» failsafe mechanism, and provided that the necessary mechanical coupling is available. We recommend that you contact your local Siemens office for the necessary information.

All SK...62… actuators are factory-fitted with a spring-return function, so that if the control signal or power supply fails, the actuator will return to the «0%» stroke position. The SK...60 actuators do not have a spring-return function. In case of a power failure these actuators remain in their current stroke position.

The Z-modes shown assume the factory-setting «direct-acting». To determine the stroke positions 0 and 100% in the valve, calibration is required when the valve/actuator are commissioned for the first time. For this purpose, the actuator must be mechanically connected to a Siemens valve (see «Compatibility») and must have a supply voltage of AC 24 V. The calibration procedure can be repeated as often as necessary. %HIRUHVWDUWLQJFDOLEUDWLRQHQVXUHWKDWWKHPDQXDODGMXVWHULVVHWWR©$XWRPDWLFª LQRUGHUWRUHJLVWHUWKHDFWXDOYDOXHV

There is a slot on the printed circuit boards of the actuators. To initiate the calibration procedure, the contacts inside this slot must be short-circuited (e.g. with a screwdriver).
Automatic calibration proceeds as follows: • Actuator runs to the «0 stroke» position (), valve closes, green LED flashes. • Actuator then runs to the «100 stroke» position 6WURNH (), valve opens, green LED flashes. 0% • Measured values are stored. The calibration procedure is finish, and the green LED now glows steadily (normal operation). • The actuator now moves to the position defined W 100% by control signal Y or Z (). • Throughout this procedure, output U is inactive, i.e. the values only represent actual positions when the green LED stops flashing and remains on continuously. /('VWDWXVLQGLFDWLRQ
