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.

If necessary, disconnect electrical connections from terminals.• The valve must be re-commissioned only with the actuator correctly assembled.DisposalThe actuator includes electrical and electronic components and must not be disposed of as domestic waste.Current local legislation must be observed .WarrantyThe application-related technical data (∆ p max , ∆ p s , leakage, noise levels and service life) is valid for the Siemens actuators only in conjunction with the Siemens valves listed in the section on «Compatibility».Before using these actuators with third-party valves, written approval must be obtained from Siemens Building Technologies.
