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.Before starting calibration, ensure that the manual adjuster is set to «Automatic»in order to register the actual values.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 (1), valve closes, green LED flashes.• Actuator then runs to the «100 stroke» position(2), valve opens, green LED flashes.• 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 by control signal Y or Z (3).0%t100%Stroke123• 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.LED Display FunctionActionGreenOn • Normal operationAutomatic operation, no problems Flashing• Stroke calibration in progress Wait until calibration is complete (LED stops flashing)RedOn• Faulty stroke calibration• Internal error Check mountingRe-start stroke calibration(by short-circuiting calibration slot)Replace electronics Flashing • Inner valve jammed Check the valve Off• No power supply •Faulty electronicsCheck mains Replace electronicsOverride control NoteStroke calibrationLED status indicationConnectionterminals Stroke calibrationLED status indicationDIL switchesFunctions see below ONOFFDIL switches Selection ofcontrol signal Selection offlow characteristicON DC 4 ... 20 mA Linear* OFF DC 0 ...10 V Equal percentageConnectionterminalsStroke calibrationRotary switches LOand UPLEDstatus indication6/147/14• With normally-closed valves, «direct-acting» means that with a signal input of 0 V,the valve closes (applies to all Siemens valves listed under «Compatibility» on page 3)• With normally-open valves, «direct-acting» means that with a signal input of 0 V, the valve is open.4 mA 0 Ω20 mA 1000 ΩThe mechanical spring-return function is not affected by the direction of operation selected.*The smallest adjustment is 3 V;control with 0…30 V is only possible via Y.Selecting the direction of operationNoteStroke limit control and sequence control8/14ASC1.6 auxiliary switch –Switching point 0 … 5 % stroke5434561Z 08ASZ6.5 stem heater − For media below 0°C − Mount between valve and actuatorEngineering notesThe actuators must be electrically connected in accordance with local wiring regulations and with the wiring diagram on page 12.Regulations and requirements designed to ensure the safety of people and property must be observed at all times.The ASZ6.5 stem heater has a heat output of 30 VA and is required to keep the valve stem free of ice in the cooling range 0 °C ... −25 °C. In this case, in order to ensure adequate air circulation, the actuator bracket and the valve stem must not be insulated. Physical contact with unprotected hot components can cause burns.Failure to observe the above advice can result in accidents or fire.The admissible temperatures (see «Application» and «Technical data») must be observed.Mounting instructionsPermissible Not permissibleInstructions for fitting the actuator to the valve are bypacked in the actuator packaging.The instructions for accessories are enclosed with the accessories themselves.Accessories Orientation9/14Commissioning notesWhen commissioning the system, check the wiring and functions, and set any auxiliary switches, potentiometers and stroke limit devices as necessary, or check the existing settings.Cylinder with valve stem connector fully retracted → stroke = 0 %Cylinder with valve stem connector fully extended → stroke = 100 %The manual adjuster must be rotated counterclockwise to the end stop.This causes the Siemens valves, types VVF... and VXF... to close (stroke = 0%).For automatic operation, the crank (2) on the manual adjustment knob (1) must be engaged. If not engaged, turn the crank counter-clockwise until the display window (3)neither shows the scale (4) nor the crank engagement bar.124564Z 144564Z 16Engaged crank (2) on the manual adjustment knob (1)Display window with invisible scale dial and crank engagement barFor manual operation, swing out the crank (2) so that the display window (3) becomes visible.

Simultaneously, the returnspring [4] is compressed.Closing thevalveActivating the solenoid valve [5] allows the oil in the pressure chamber toflow back into the suction chamber. The compressed return spring movesthe pressure cylinder upwards. The valve stem extends and the valvecloses.ManualoperationmodeFor manual operation, swing out the crank so that the display windowbecomes visible. By rotating the crank clockwise, the pressure cylinder ismoved downwards. The display window shows the engagement bar and/orthe scale dial with stroke indication.In the manual operation mode, the positioning signals Y and Z can furtheropen the valve but cannot move to the 0 % stroke position of the valve. Toretain the manually set position, switch off the power supply or disconnectthe positioning signals Y and Z. The crank remains swung out and in thedisplay window the red indicator dial remains visible.Hinweis:When setting the controller to manual operation for a longerperiod of time, we recommend adjusting the actuator with themanual adjuster to the desired position. This guarantees thatthe actuator remains in this position for that period of time.Attention: Do not forget to switch back to automatic operationafter the controller is set back to automatic control.2Automatic operation mode For automatic operation, turn the manual adjuster clockwise to the end stop. The pressure cylinder moves upwards to the 0% stroke position of the valve. In the display window, the read scale disappears. Afterwards, swing the crank closed.Minimal volumetric flow The actuator can be manually adjusted to a stroke position > 0%, allowing its use in applications requiring a constant minimal volumetric flow.SKC32.. SKC82..3-position control signal The actuator is controlled by a 3-position signal either via terminals Y1 or Y2 and generates the desired stroke, which is transferred to the valve stem:● Voltage on Y1: Piston extends Valve opens● Voltage on Y2: Piston retracts Valve closes● No voltage on Y1 and Y2: Piston and valve stem remain in therespective positionSKC62.. SKC60Y positioning signalDC 0...10 V and/or 0...1000 Ω, DC 4...20 mA The actuator is either controlled via terminal Y or override control Z. The positioning signals generate the desired stroke by means of the above described principle of operation, which is transferred to the valve stem: ● Signal Y increasing: Piston extends Valve opens ● Signal Y decreasing: Piston retracts Valve closes ● Signal Y constant: Piston and valve stem remain in therespective position● Override control Z: See Functions [➙8]Frost protection monitor Frost protection thermostat A frost protection thermostat can be connected to the SKC6.. actuator. The added signals from the frost protection monitors QAF21.. and QAF61..require the use of SKC62UA actuators.

This isnot the case when combined with Siemens HVACcontrollers. The reason is that SIMATIC has a higherresolution and faster response time.Use the potentiometer as voltage divider on the 3-wireconnection. Powering the potentiometer over the wiper mayshorten the life cycle of the potentiometer.
