4 Functions and control 4.1 3-position control A 3-position signal drives the actuator via connection terminals Y1 or Y2. The required position is transferred to the valve.
The specified positioning times refer to the respective nominal stroke / nominal angular rotation. Since the end positions of rotary actuators are inside the actuator, the following remarks refer to stroke actuators. The resulting effective strokes vary, depending on the type of valve, resulting in shorter or longer actuator positioning times. Stroke of valve-actuator combination [mm] Positioning times stroke model Positioning time [sec] Legend diagram A B A…B Notes Mechanical end position in SAX..
Notes 4.1.1 Combination with RVD.. controller for direct domestic hot water distribution by heat exchanger The design based slow reaction on control signals of SAX31.., SAX81.., SAV31.., SAV81.., SAY31.., SAY81.., SAL31.. und SAL81.. actuators doesn’t allow the actuator to react on very short control pulses. Only control pulses with a length greater than 300 ms allow a sufficient reaction. Especially the direct domestic hot water control does not allow such long control pulses.
4.2 Modulating control The modulating positioning signal drives the actuator steplessly. The positioning signal range (DC 0...10 V / DC 4...20 mA, 0...1000 Ω) corresponds in a linear manner to the positioning range (fully closed...fully open, or 0…100 % stroke).
4.3 DIL switches Function module AZX61.1 Acting direction Sequence control OFF 1) Direct acting positioning signal Y or Z Sequence control not active ON 1) Reverse acting positioning signal Y or Z Sequence control (signal adaptation) 1) Factory setting: All switches set to OFF The function module may not be used in combination with SA..61../MO. 4.3.

4.5 Acting direction and flow characteristic The selection of changeover of acting direction and characteristic with the DIL switches of the function module AZX61.1 depends on the type of actuator (with or without fail safe function) and the associated type of valve (valve characteristic, push to open, pull to open). When the positioning signal increases (DC 0…10 V, DC 4…20 mA, 0...
Actuator Positioning signal Y, Z Actuator Position feedback U Direct acting Reverse acting Y, Z H U 4.7 Positioning signal Stroke Position feedback Acting direction: direct Acting direction: reverse Position control with ClosedPositionSynchronization Within SAX/SAV/SAL61/SAY61.. actuators the position control works based on the HALL-sensor pulses from the brushless DC-motor calculating with an internal stroke model calculating the actual position.
After synchronization the actuator follows the control signal again. 4.7.1.1 Active forced position input on Z If after return to automatic mode a signal on Z is active (GND, AC/DC 24 V or 0…1000 Ohm) the ClosedPosition-Synchronization is deactivated as long as the signal on Z remains. After Z is deactivated the ClosedPosition-Synchronization will be performed. Note ClosedPosition-Synchronization is only automatically activated after manual operation.
Note · Observe status indication (actuator LED) during and after calibration (page 70). · If the actuator does not detect the second end position within an appropriate stroke range (SAX.., SAY.. max. 25 mm; SAV.. max. 45 mm), the first end stop will be adopted and the actuator operates with a working range of 20 mm, respectively 40 mm. 4.9 Signal priorities The actuators are controlled via different interlinked positioning signal paths (positioning signal “Y“, forced control input “Z“, manual adjuster).
Example The supposed position is 50%, Y = 2 V, the actuator travels 30% of the stored valve stroke in the direction of "Actuator’s stem retracted". If the actuator reaches the seat within this 30% travel, it interprets the position as "Valve fully closed" and shifts the position of the valve’s stroke accordingly without changing the extent of travel. From now on, the actuator follows the changed valve stroke position.
4.12 SA..61.. only Forced control Z Forced control is affected by changeover of acting direction.
After a power failure, valve seat identification is not active – the actuators without fail safe function define their stroke position upon return of power at 50% and automatically set their internal setpoint in register 1 to the startup setpoint (register 516). The actuator closes at this setting. There is a short-term deviation between the setpoint and the internal stroke position. When the valve plug reaches each seat for the first time, the actuator readjusts its stroke mode.
Calibration takes place in the following phases: · Actuator drives to H0 (1), valve closes. Detection of upper end position. · Actuator drives to H100 (2), valve opens. Detection of lower end position. · The detected values are stored (3). Then the actuator follows the positioning signal. · If the actuator does not detect the second end position within an appropriate stroke range (max. 25 mm), the first end stop will be adopted and the actuator operates with a working range of 20 mm.

· If clogging/a blockade occurs during the self test, the test is failed, even if the device clears it within 3 tries. Register 256 “Reset” The actuator supports the following re-initialization / reset behaviour: · Local reset by push-button · Remote reset: Using “Remote-Reset” command. Effect of reset: · Process values except actual value and setpoint: set to ex-works default values.

4.14.2 Coupling SAX.., SAV.. The stem coupling (1) and neck coupling (2) ensures full backward compatibility with all types of Siemens large-stroke valves produced since 1975. SAL.. Mounting sets are available for use with butterfly and slipper valves. 4.14.3 Manual adjuster Automatic When the motor drives the manual adjuster turns. Thus in automatic mode, the manual adjuster is used for indication of travel.
4.14.4 Indicators A Indication of travel B Scale C Indicator D LED Status indication Position indication Operational status indication In Automatic mode, the manual adjuster serves for the indication of travel. See "Automatic" (page 69). Position indication Position indication is on 2 opposite sides. When turning the manual adjuster, the indicator moves in the same direction. The scale indicates the stroke. When reaching the stops, the valve is either fully open or fully closed.
4.14.5 Electrical accessories Auxiliary switch ASC10.51 The auxiliary switch ASC10.51 switches on or off when a certain position is reached. The switching point can be set between 0…100%. AC 24 V...230 V / 6 (2) A S1 Switching point for S1–S2 and S1–S3 cannot be set separately. If S1–S2 is open then S1–S3 is closed. S3 S2 Adjustable switching point Application example: Potentiometer ASZ7.5/.. Potentiometer ASZ7.
Function module AZX61.1 Function module AZX61.1 offers the following choices for changing control: · Changeover of acting direction (page 55) · Sequence control (page 54) Stem heating element ASZ6.6 Stem heating element ASZ6.6 prevents the formation of ice on the stem when medium temperatures drop below 0 °C. It is suited for universal use with valves having a stem diameter of 10 or 14 mm. The stem heating element heats up to 85 °C.
