Note: ASZ7.5

For the combination SIMATIC S5/S7 and position feedback message, we recommend actuators with DC 0…9.8 V feedback signals.

The signal peaks that occur in the potentiometer ASZ7.5 may result in error messages on Siemens SIMATIC. This is not the case when combined with Siemens HVAC controllers. The reason is that SIMATIC has a higher resolution and faster response time.

2.7 Product replacements

Replacement of SQX.. / SQL.. actuators by SAX.. / SAL.. actuators.

Note

· When replacing actuators consider positioning force, torque and positioning times.

· Adjust in the controller the parameter "Running time" respectively "Positioning time", to ensure stable control.

· The replacement of accessory items needs to be taken into consideration also. In that case, compatibility is not necessarily ensured.

2.9 Sizing

2.9.1 Parallel operation of actuators

3-position actuators must have one specific controller each, refer to "Connection diagrams" (page 82).

Up to 10 actuators can drive in parallel on a controller output with a rating of 1 mA. Modulating actuators have an input impedance of 100 kΩ.

The Modbus converter is designed for analog control on 0..10 V on the actuator side. Note: Keep the setting of the analog signal on the actuator as is (switch 1 to "OFF"), adjustment is not allowed.

The actuators are factory-set to equal-percentage characteristic curve. Note: The DIL switch (actuator-internal changeover of characteristic curve) must be set to "log" (switch 2 to "OFF").

2.9.2 Permissible cable lengths and wire cross-sectional

areas

Cable lengths and wire cross-sectional areas depend on the following criteria of the actuators:

· Current draw

· Permissible voltage drop across the power supply lines

The control accuracy of the modulating actuators can be improved by using 4-wire connections, thus ensuring that voltage drops on G0 will not distort the positioning signal. When determining the cable length and the wire cross-sectional area, adherence to the permissible operating voltage tolerance at the actuator is of importance, in addition to the permissible voltage drop across the operating voltage and signal lines (see table below).

AC/DC 24 V

G0, G G0, Y, U

Max. permissible

voltage drop

4% each (total of 8%) 1% each (at DC 0…10 V)

The following criteria must be considered:

· With modulating control, the permissible positioning signal error must not exceed 1%, the reason being the voltage drop on the G0 wire.

· The voltage drop, caused by charging current peaks in the actuator’s DC circuit, must not exceed 2 Vpp.

· If the G0 line is not correctly sized, load changes of the actuator due to changes of the DC voltage drop might lead to self-oscillations.

· The operating voltage drop at AC/DC 24 V may be a maximum of 8% (4% above the G0 wire).

The following diagram can be used to determine the cable lengths and wire crosssectional areas.

3.2.2 Commissioning Modbus RTU

The devices were developed specifically for use with Climatix push-button configuration as described in document CE1A39751).

As an alternative, the bus can be configured via the local HMI; see Section User interface, pg. 50.

Check the following during commissioning:

· Bus configuration (address, baud rate, type of transmission and optional termination). Standard address 255 allows for installation and commissioning of several actuators simultaneously without mutual interference.

· The actuator parameters (direction for opening, position limits, position adjustment etc.) can be read via the Modbus register.

Documents can be downloaded at http://www.siemens.com/bt/download

Full or partial configuration via bus

The actuators can be configured via bus connection if the settings prior to commissioning allow for a connection to the Modbus master/programming tool (no address conflicts and correct baud rates/transmission format settings).

· Full configuration via bus: With a unique Modbus address, a connection can be established from Modbus master/programming tool following startup by means of the preset transmission format and baud rate (or auto-baud).

· Partial configuration via bus: If the Modbus address is not unique, it must first be set to a unique value, either by using the address input with push button (cf. page 51) or by setting the address to 246 with push button press > 5s und < 10s (cf. page 50). Full configuration via bus: With a unique Modbus address, a connection can be established from Modbus master/programming tool following startup by means of the preset transmission format and baud rate (or auto-baud)..

With an existing connection, the bus and actuator parameters can be set to target values via the bus. During write access to the bus parameters, "1 = Load“ must be written to register 768 within 30 seconds to ensure the changes are not discarded.

Example: The table shows the register values before and after the change via bus access.

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.. and SAV81.. actuators doesn’t allow the actuator to react on very short control pulses. Only control pulses with a length greater than 400 ms allow a sufficient reaction.

Especially the direct domestic hot water control does not allow such long control pulses. The specific optimized control loops – equipped with an SIGMAGYR RVD.. controller and Acvatix SQS359.05 actuator– work with pulses down to 40 ms.

SAX31.. and SAX81.. are not able to work with these short pulses. The following table gives alternatives which actuators can be used within these control loops.

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...1000 Ω), the objective is to have the valve’s volumetric flow V rising, but to fully open the valve, V = 100% (NO = normally open), or to fully close it, V = 0% (NC = normally closed) in the event of a power failure.

4.7 Position control with ClosedPosition- Synchronisation

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. This kind of control is more accurate and wearless compared with a physical element for position measurement and grants a precise position control with high resolution.

During manual operation the motor is declutched from the gear train and the internal position control get’s not sensor pulses. So real position will deviate from the internally calculated position. As a consequence the position feedback on terminal U is set to “0V” during manual operation.

To grant – after manual operation – that real mechanical position and internal position control are matching all SA..61.. operate after manual operation an automatic ClosedPosition-Synchronisation.

4.7.1 ClosedPosition-Synchronisation

Returned into automatic operation the actuator runs for 0.5.. 2 s into opening direction to grant secure closed-position detection. Then the actuator runs into closed position (seat A-AB in the valve). Reaching the closed position the internal stroke model is synchronized. Positioning signal, position feedback and meachnical position now match perfectly again. With this function it’s granted that the position feedback U – which was zero during manual operation and synchronization - always represents the real mechanical position of the actuator.

62 / 92

Siemens Actuators SAX.., SAY.., SAV.., SAL.. for valves CE1P4040en Building Technologies Functions and control 2018-12-05

Page 63

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-Synchronisation is deactivated as long as the signal on Z remains. After Z is deactivated the ClosedPosition-Synchronisation will be performed.

Note

ClosedPosition-Synchronisation is only automatically activated after manual operation. A power failure does not activate this function automatically, to avoid that all actuators in a section close in parallel.

If the customer likes synchronization also after a power failure he should take care that the plant restarting routine drives the actuator automatically into an end position. This will also synchronies the internal position control and the real position.

4.8 Calibration

To match the actuator to production-related mechanical tolerances of the individual valves, accurate positioning and position feedback must be ensured, if calibration is performed when the plant is commissioned (page 46). During commissioning, the actuator detects the valve’s end positions and files the exact stroke in its internal memory.

Calibration takes place in the following phases:

· Actuator drives to H0 (1), valve closes. Detection of upper end position.

· Actuator drives to H Detection of lower end position.

· The detected values are stored (3). Then the actuator follows the positioning signal.

(2), valve opens.

100

Note

Examples

· Observe status indication (actuator LED) during and after calibration (page 74).

· 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). The signal paths are assigned the following priorities:

Priority Description

(highest)

(lowest)

Manual

Automatic mode

Operated (30%) and

engaged

Bold printing = positioning signal currently active

The manual adjuster always has priority 1, thus overriding all signals active at “Z“ or “Y“, independent of whether or not power is applied. Only SA..61..: As soon as a valid positioning signal is active at input “Z“, the position is determined via positioning signal “Z“ (forced control). Prerequisite: The manual adjuster is not used. The position is determined via positioning signal ”Y”. The manual adjuster is not used and on Z there is no active signal.

4.10 Detection of valve seat

The actuators feature force-dependent valve seat detection. After calibration, the exact valve stroke is filed in the actuator’s memory. When the actuator reaches the respective end of stroke, it does not hit the valve’s seat at full speed, but stops for 5 seconds at about 1% before the stored position is reached. If the positioning signal stays at 0% or 100%, the actuator travels to the calculated end position at reduced positioning speed and builds up the required nominal force. This function extends the actuator’s service life since the dynamic forces are reduced when approaching the valve seat and there will be less strain on the gear train. In addition, the actuator’s oscillations in the case of instable control are suppressed. If no force is built up in the calculated end position (e.g. in the event of temperature effects for instance), the actuator continues to operate at a reduced positioning speed until the nominal positioning force is restored. This ensures that the valve always fully closes. After a power failure, valve seat identification is not active – the actuators define their stroke position on power resoration to be at 50%. From now on, the actuator follows the positioning signal. When the valve plug reaches its seat for the first time, the actuator readjusts its stroke model.

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. This means: New position 0%, Y = 2 V, actuator travels 20% of the stored valve stroke in the direction "Actuator’s stem extended".

4.11 Detection of foreign bodies

The actuator detects when the valve is clogged and adjusts its operational behavior accordingly to prevent damage to itself or the valve. If the actuator hits an obstacle within the calibrated stroke and is not able to overcome it with its nominal positioning force, it stores the position at which the obstacle was hit. Depending on the direction of travel, as …

· "Lower limit of valve clogging", if the clogging was detected when traveling in the direction of "Actuator’s stem retracting".

· "Upper limit of valve clogging", if the clogging was detected when traveling in the direction of "Actuator’s stem extending".

Now, the actuator status LED blinks green and the actuator only follows the positioning signal between the positions "Actuator’s stem retracted" and "Upper limit of valve clogging" or "Actuator’s stem extended" and "Lower limit of valve clogging". After detection of clogging, 3 attempts are made to overcome clogging by traveling about 15% in the opposite direction and then trying again to overcome the position of clogging. If the attempts made are unsuccessful, the actuator continues to follow the positioning signal within the restricted range only and the actuator LED continues to blink green (refer to "Indicators" on page 74).

4.13.1 Detection of valve seat

The actuators feature force-dependent valve seat detection. After calibration, the exact valve stroke is filed in the actuator’s memory. When the actuator reaches the respective end of stroke, it does not hit the valve’s seat at full speed, but stops for 5 seconds at about 1% before the stored position is reached. If the positioning signal stays at 0% or 100%, the actuator travels to the calculated end position at reduced positioning speed and builds up the required nominal force. This function extends the actuator’s service life since the dynamic forces are reduced when approaching the valve seat and there will be less strain on the gear train. In addition, the actuator’s oscillations in the case of instable control are suppressed. If no force is built up in the calculated end position (e.g. in the event of temperature effects for instance), the actuator continues to operate at a reduced positioning speed until the nominal positioning force is restored. This ensures that the valve always fully closes. 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.

Example

Setpoint prior to power outage 35%, no manual adjustment during the power outage. Internal stroke position value after return of power 50%. Internal setpoint after return of power equal to startup setpoint (register 516, here 0%). The actuator moves 35% in the direction of "Retract actuator stem" and reaches the valve seat (if the setpoint has not been changed in the meantime). The internal stroke position is set to 0%. The actuator now follows the changed valve stroke position effective immediately.

4.13.2 Detection of foreign bodies

· "Lower limit of valve clogging", if the clogging was detected when traveling in the direction of "Actuator’s stem retracting".

· "Upper limit of valve clogging", if the clogging was detected when traveling in the direction of "Actuator’s stem extending".

the positioning signal within the restricted range only and the actuator LED continues to blink green (refer to "Indicators" on page 74).

As long as the external setpoint is greater than the position of the high limit valve clogging, the deviation between the setpoint and position feedback in register 769 is displayed with the warning “Mechanical error, device blocked, manual intervention or calibration.” The cable adapter LED is red. The warning is reset if the external setpoint drops below the high limit valve clogging, since the setpoint and stroke position are once again the same. The cable adapter LED switches to green blinking (=communication).

4.13.3 Calibration

Calibration takes place in the following phases:

· Actuator drives to H0 (1), valve closes. Detection of upper end position.

· Actuator drives to H 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.

(2), valve opens.

100

Note

The internal position feedback is set to 0% during calibration. For a setpoint >0%, the actuator detects calibration based on the deviation between setpoint and stroke position and reports this in Register 769 with the warning “Mechanical error, device blocked, manual intervention or calibration”. The actuator LED blinks green, the cable adapter LED is red. After calibration is completed, the actuator follows the external setpoint, the warning is reset, the actuator LED changes to continuous green and the cable adapter LED blinks green (communication active).

Observe status indication (actuator LED) during and after calibration (page 74). The calibration cannot be started via the bus.

4.13.4 Manual adjustment

The actuator’s internal stroke position measurement is inactive during manual adjustment. The position feedback changes to 0% once the manual adjuster is pressed and remains on the value during manual adjustment. The actuator detects manual action based on the deviation between the setpoint and the stroke position and after 10 seconds reports in register 769 with the warning “Mechanical error, device blocked, manual intervention or calibration”. The actuator LED blinks green, the cable adapter LED is red.

Upon return to automatic mode, the actuator synchronizes to stroke position 0%. After the synchronization, the actuator follows the pending setpoint, the actuator LED changes to continuous green and the cable adapter LED blinks green (communication active). The warning in register 769 is reset.

Function description

Function Reg. Description

Override control

2 The actuator can be operated in override control for commissioning /

maintenance purposes or system-wide functions (e.g. night-cooling).

· Manual override: When the manual adjuster is used, a mechanical jam will

be detected if a mismatch between setpoint and actual position persists for more than 10s.

· Remote override: The actuator enters this state when an override command

is sent over the bus.

· Available commands:

o Extend / Retract

Stop (with braking distance compensation)

Backup mode

513, 514, 515

· In case the communication to the controller is lost, the device can be

configured to go into a defined state.

· Default setting mode is “keep last setpoint”, i.e. in case of communication

loss, the device controls to the last received setpoint.

· If the backup mode is enabled, it can be configured as follows:

o go to a predefined backup position

keep current position

Restarting the device

256 Restarting is possible by:

· Power-reset (turning operating voltage off and on) or

· by “Reinitialize” command.

à Device re-initializes and sets all process values except actual

value (= 50%) and setpoint (= startup setpoint) to defaults.

Reset

The actuator supports the following re-initialization / reset behaviour:

· Local reset by push-button

· Remote reset: Using “RemoteFactoryReset” command.

Effect of reset: Process values except actual value and setpoint: set to ex-works default values.

· Network parameters (register 513-516 and 764-768) are reset only in case

of local reset, not by remote reset (otherwise loss of communication). Not reset are: Counters, device info, and factory data.

Self test

256 When triggered, the self test drives the actuator to the detected limits and sets

the flags in register 769 according to the result (bit 09 = 1à”failed” or bit 10 = 1 à “passed”). The self test is not passed when the limits were not reached from the lower end (results in jam). If the Min/Max limits can be exceeded, the self test is not evaluated as failed.

Function principle

SAL..

SAX.., SAV..

Incoming positioning signals are translated to positioning commands for the motor.

A gear train transmits the motor’s positioning steps to the output stage (valve coupling). Attached to the gear train are the electrical and mechanical accessory items and the manual adjuster.

In the case of the rotary actuators, the adjustment to the required torque is made in the output stage. With the stroke actuators, the translation from rotary to stroke movement takes place in the output stage.

Manual operation

The stem coupling (1) and neck coupling (2) ensures full backward compatibility with all types of Siemens large-stroke valves produced since

1975.

4.14.3 Manual adjuster

Mounting sets are available for use with butterfly and slipper valves.

When the motor drives the manual adjuster turns. Thus in automatic mode, the manual adjuster is used for indication of travel. If the manual adjuster is held firm in this mode, there is no transmission of power to the gear train.

When pushing the manual adjuster down (1), it engages and the actuator can be manually operated.

Stroke actuator: When turning the manual adjuster in clockwise / counterclockwise direction (2), the actuator’s stem retracts / extends.

Rotary actuator: The actuator spindle turns in the same direction.

An overload protection prevents damage to the manual adjuster

Fixing the position

Upon actuation and locking the slide switch, the manual adjuster remains engaged.

When in this mode, do not turn the manual adjuster.

Disengaging the fixing

When resetting the slide switch, the manual adjuster returns to automatic mode.

The auxiliary switch ASC10.51 switches on or off when a certain position is reached. The switching point can be set between 0…100%.

When using an auxiliary switch, position feedback can trigger an automatic stop of the circulating pump in the end position "Fully closed".

Potentiometer ASZ7.5 delivers an ohmic value to the controller giving the exact

position of the actuator (continuous position feedback). A slip clutch prevents damage to the potentiometer in the mechanical end positions. This is also used for accurate balancing of the potentiometer in the fully closed position.

Ohmic value between P2-P1 increases with stroke H or rotation, ohmic value between P2-P3 decreases.

Flow characteristic

The end values of the potentiometers refer to the maximum stroke / maximum angular rotation of the actuators. For this reason, the resulting values in operation deviate, depending on the type of valve used in combination with the actuator. The potentiometer's starting point can be very accurately adjusted during installation (refer page 37).
