1.1

General

KNX systems provide an attractive solution that meets the most demanding residential, commercial and public buildings requirements. High living standards, comfort and safety can be easily combined with costeffectiveness and environmental awareness using KNX bus systems from ABB. KNX products cover the entire range of buildings applications, from illumination and blind control to heating, ventilation, energy management, security and surveillance. These requirements can be met cost-effectively with minimal planning and installation effort using the ABB KNX. Furthermore, flexible room usage and continuous adaptation to changing requirements are simple to implement. SA/S Switch Actuators fulfill individual requirements in industrial, commercial and public buildings as well as in the private sector for controlling switchable loads, e.g.:

•

Illumination

•

Heating control

•

Signaling equipment

Certain types of Switch Actuator can also detect and monitor load current via a threshold value function.

Based on the load current detected, responses can be triggered via KNX and the load can be switched off directly or switched via KNX.

1.2 Product and functional overview

SA/S 12.16.6.1

ABB i-bus

®

KNX SA/S Switch Actuators are modular installation devices with module widths of

2/4/8/12 units in Pro M design for installation in a distribution board.

Connection to the ABB i-bus

®

is established via a bus connection terminal on the front.

The Switch Actuators require no auxiliary voltage.

The assignment of the physical address as well as the parameterization is carried out with

Engineering Tool Software (ETS), version ETS2 V1.3a or higher. If using ETS3 or ETS4 you will need to import the corresponding application program.

SA/S 8.16.6.1

SA/S 4.16.2.1

SA/S 2.10.2.1

SA/S 8.6.2.1

Please note

The illustrations of the parameter windows in this manual correspond to the ETS3 parameter windows. The user program is optimized for ETS3.

In ETS2 the parameter page for any parameter being used may split automatically.

The Switch Actuators can switch 2 to 12 independent electrical AC or three-phase loads via

KNX with floating contacts. With SA/S x.16.6.1 types it is possible to detect the load current for each output. The outputs of the 6 A, 10 A, 16 A and 16/20 A Switch Actuators can be switched on and off manually.

Switch Actuators SA/S x.16.6.1 and SA/S 12.16.5.1, which have the highest switching capacity

(C-load), are particularly well-suited for switching loads with high peak inrush currents, e.g. lighting equipment with compensation capacitors or fluorescent lamp loads (AX) to EN 60 669.

The following functions can be set individually for each output:

•

Time and ON/OFF delay functions

•

Staircase lighting function with warning and modifiable staircase lighting time

•

Recall of scenes/presets via 8/1 bit commands

•

Logical functions AND, OR, XOR, GATE function

•

Status messages

•

Forced operation and safety functions

•

Response to threshold values

•

Control of electro-thermal valve drives

•

Selection of the default state on bus voltage failure and recovery

•

General

On Switch Actuators with current detection, SA/S x.16.6.1, each output also features the load current detection function with parameterizable response to two current threshold values. The current value can be sent via the bus. Individual outputs in the Switch Actuators can be copied or exchanged to minimize programming work.

The SA/S x.16.6.1 and SA/S x.16.5.1 are suitable for rated currents up to 20 A and have C-load switching capacity.

Important

The Switch Actuator types SA/S x.16.6.1 differentiate from the predecessor types SA/S x.16.5S by new hardware and software.

While there have been few changes to the functions of the software, the hardware has been redesigned for load currents up to 20 A. Furthermore, the current detection has been optimized and its accuracy has been enhanced by a factor of four.

Existing projects can be converted to ensure operation with the new hardware / software.

For further information see: Conversion of previous application program versions , p. 53 .

For faster and simpler commissioning, it is also possible to copy the parameter settings of the outputs to others or to exchange them with another output.

For further information see: Copying and exchanging parameter settings , p. 57 .

Please note

Only load currents with a sine wave characteristic can be detected correctly. On other signal types, e.g. phase angle or inverse phase angle control signals, the detected current value is distorted. In this case, the measured value is meaningless.

Current values less than 20 mA are indicated as a 0 mA value via KNX. For small load currents that are just above the minimum detection threshold of 20 mA, it is possible that a value of 0 mA is displayed due to the inaccuracies, even though a current is flowing.

Example

A current of 25 mA is flowing. The Switch Actuator detects 5 mA due to the tolerances. This value is less than the minimum current detection limit of 20 mA and is thus sent as a 0 mA value via KNX.

Important

The current detection and monitoring function should not be used for safety-related applications. The

Switch Actuator cannot assume the function of a circuit-breaker or RCD (earth-leakage circuit breaker).

If the load current detection is used for equipment fault detection that only causes a slight change of under 30 mA, mains voltage and current fluctuations due to ambient influences, e.g. temperature, natural ageing of the device or a non-sinusoidal current, play a significant role. Even when the current changes are detected by the Switch Actuator, the detected current changes do not necessarily mean that a device has malfunctioned.

2.8 Ballast calculation

The electronic ballast is a device for operating gas discharge lamps, e.g. fluorescent lamps. During normal operation, it converts the mains voltage to an optimum operating voltage for gas discharge lamps. It also enables them to ignite (start) via capacitor circuitry.

With the original choke/starter circuitry the lamps switch on consecutively, with the electronic ballast all fluorescent lamps switch on practically simultaneously. If switch-on occurs at the mains voltage peak, the buffer capacitors of the electronic ballast cause a high but very short current pulse. When using several ballasts on the same circuit, the simultaneous charging of the capacitors may result in very large system inrush currents.

This peak inrush current I p

is to be considered when designing the switch contacts as well as when selecting the respective circuit protection. The effects of the electronic ballast peak inrush current and the associated limitation of the number of electronic ballasts on the SA/S are examined below.

The inrush current of the electronic ballast depends not only on the wattage but also on the type, the number of elements (lamps) and on the manufacturer. For this reason, the given maximum number of connectible electronic ballasts per output can only relate to a defined type of electronic ballast.

For a different ballast type, this value can only represent an estimation.

In order to properly estimate the number of electronic ballasts, the peak inrush current I p

and the associated pulse width of the electronic ballast must be known. In the meantime, these values are stated by manufacturers in the technical data or are available on request.

Typical values for single element electronic ballasts with T5/T8 lamps are:

Peak inrush current 15…50 A with a pulse time of 120…200 µ s.

The Switch Actuator relays have the following maximum starting values:

= 33.9 A (147.1 µ s)

For Switch Actuator SA/S 4.16.6.1 this results in: maximum number of electronic ballasts/output = 600 A/34 A = 17 electronic ballasts

This number has been limited to 12 electronic ballasts in conjunction with a B16 miniature circuit breaker. If more electronic ballasts are connected, the miniature circuit breaker may trip during switch on.

For Switch Actuator SA/S 4.6.1.1 this results in: maximum number of electronic ballasts/output = 200 A/34 A = 5 electronic ballasts

2.9 AC1, AC3, AX, C-load specifications

In Intelligent Building Control, different switching capabilities and performance specifications, required by special applications, have become established in industrial and residential systems. These performance specifications are rooted in the respective national and international standards. The tests are defined to simulate typical applications, e.g. motor loads (industrial) or fluorescent lamps (residential).

Specifications AC1 and AC3 are switching performance specifications which have become established in the industrial field.

Typical application:

AC1 – Non-inductive or slightly inductive loads, resistance furnaces

(relates to switching of resistive loads, cos



= 0.8

)

AC3 – Squirrel-cage motors: starting or switching off during running

(relates to (inductive) motor load, cos



= 0.45)

AC5a – Switching of electric discharge lamps

These switching performances are defined in standard EN 60 947-4-1 Contactors and motor-starters –

Electromechanical contactors and motor-starters .

The standard describes starters and/or contactors that were originally used primarily in industrial applications.

The designation AX has established itself in the field of building services technology.

AX relates to a (capacitive) fluorescent lighting load.

Switchable capacitive loads (200 µ F, 140 µ F, 70 µ F or 35 µ

F) are referred to in conjunction with fluorescent lamp loads.

This switching capacity refers to standard EN 60 669 Switches for household and similar fixed electrical installations – General requirements , which deals primarily with applications in building services engineering. For 6 A devices, a test with 70 µF is required and for devices exceeding 6 A, a test with

140 µF.

SA/S | 2CDC 505 056 D0208 43

ABB i-bus



KNX

Device technology

The switching capacity specifications AC and AX are not directly comparable. However, the following switching capacity capability can still be determined:

The lowest switching capacity corresponds with the specification

AC1 – mainly for ohmic loads.

The following switching capacity should be rated higher

AX – fluorescent lamp loa ds, under the standard: 70 µF (6 A), 140 µF (10 A, 16 A).

The highest switching capacity is designated by

AC3 – motor loads,

C-load – fluorescent lamp loads (200 µF).

Both specifications are almost equivalent. This means that a device which has met the test for AC3 under

EN 60 947 will most probably meet those under EN 60

669 with 200 µF.

In conclusion, generally speaking:

•

Users or customers primarily involved with industrial applications will tend to refer to AC3 switching capacities.

•

Users involved with building or lighting technology will more often than not refer to an AX switching capacity or Cload (200 µF loads).

The switching capacity differences must be considered when selecting a Switch Actuator.

2.10 Current detection specifications

The Switch Actuators with current detection are recognizable by a number 6 as the third number of the type designation, e.g. SA/S 2.16.

6 .1.

This is a Switch Actuator with integrated load current detection.

Each output features its own current detection with evaluation electronics, which can be parameterized separately.

For further information see: Parameter window A: Current Detection , p. 101

The current recognition detects sinusoidal load currents with a 45-

60 Hz frequency range. Non-sinusoidal currents, e.g. phase angle varied or distorted currents, cause a measurement error depending on the curve type. If a DC current is superimposed, the measurement error is again considerably larger. Phase angle varied currents are generated, for example, by a current rectifier.

The current detection principle in the Switch Actuator is based on the conversion of sinusoidal load currents by a transformer. On the secondary side of the transformer, the transferred value is rectified and smoothed by an RC element. The resulting value is multiplied with the fixed factor 1/

√

2, producing an RMS value. The factor 1/

√

2 is derived from the crest factor Û/U rms

=

√

2 for a sinusoidal curve type.

44 2CDC 505 056 D0208 | SA/S

ABB i-bus



KNX

Device technology

For a non-sinusoidal curve type, the resulting values can diverge significantly from the real RMS value.

This measurement method is used in most commercially available analog and digital multimeters that are calibrated for sinusoidal curve types.

In this case, a true RMS meter or a “non-true RMS meter” are frequently referred to, e.g. METRA Hit 13S.

Please note

With non-sinusoidal currents, there are considerable differences between a high-quality true RMS meter and the displayed values of the SA/S. For this reason, comparative measurements should be taken using a meter that is also calibrated for sinusoidal AC currents.

For technical reas ons, only currents exceeding 20 mA can be displayed. Interference is suppressed by an

RC element, and the displayed value is stabilized. The RC element has a time constant

τ

of around

300 ms. The current values are scanned cyclically with a scanning frequency of 320 ms. Thus a change in the current can be safely detected every 320 ms and sent via the bus if required. The near exact value is displayed after 5

τ ≈ 1.5 s.

The currents are represented in mA as counter values (2 byte, DTP 7.012) or floating values (4 byte,

DTP 14.019).

KNX

Device technology

It is possible to program two threshold values for each output. With an overshoot or undershoot of the current threshold value a 1 bit telegram is sent via the bus. Thus for example, the failure of equipment can be detected and displayed.

With relatively small current values (< 30 mA), natural deviations in the electrical system will be immediately noticeable, e.g. natural ageing of the equipment, voltage fluctuations through differing load levels during the day as well as distortions of the sinusoidal load current, e.g. through switching actions or frequency inverters.

The ideal observation, i.e. where the current consumption of the equipment does not change with temperature fluctuations, operating voltage deviations and ageing, should always be inspected in the actual system. The changes of the ambient conditions in practice and the associated changes in current consumption and the monitored equipment must be considered. As ambient influences cannot be eliminated in practice, detection via a current threshold model is only viable if a current change caused by tolerances and ambient influences in normal operation is less than the current change caused by equipment failure.

Recommended approach when monitoring loads that are close to the detection tolerances of the SA/S current detection:

•

Connect the complete circuit to the SA/S output.

•

Close the circuit and operate loads in the typical operating range.

•

In ETS, set the data point types of the communication object and start the ETS project group monitor in order to display the current value.

•

Observe current value I

A

via KNX until a constant current is indicated.

•

Cause equipment failure and observe the current value I

F

again.

•

Determine the difference in current I

D

= I

A

– I

F

.

•

Compare the difference in current I

D

with the current detection tolerances. The current difference must be significantly larger than the accuracy of the current detection (2 % of I

A

+/-

20 mA).

•

Set the current threshold in SA/S so that it is as near as possible to the determined failure current:

I

2.11 Assembly and installation

ABB i-bus



Switch Actuators are modular installation devices for installation in the distribution board on

35 mm EN 60 715 mounting rails.

The mounting position can be selected as required.

The electrical connection is implemented using screw terminals. The connection to the bus is implemented using the supplied bus connection terminal. The terminal designations are located on the housing.

The device is ready for operation after connection to the bus voltage.

Accessibility of the devices for the purpose of operation, testing, visual inspection, maintenance and repair must be provided compliant to VDE 0100-520.

Commissioning requirements

To commission the Switch Actuators, a PC with ETS and an interface, e.g. USB or IP, are required.

The device is ready for operation after connection to the bus voltage.

The installation and commissioning may only be carried out by electrical specialists. The appropriate standards, guidelines, regulations and specifications should be observed when planning and setting up electrical installations.

•

Protect the device from damp, dirt and damage during transport, storage and operation.

•

Only operate the device within the specified technical data!

•

The device should only be operated in an enclosed housing (distribution board)!

Manual operation

With the exception of SA/S x.6.1.1 variant, the Switch Actuators can be manually operated. They can be switched on or off with a button on the relay. The button simultaneously indicates the contact position.

Important

The Switch Actuator does not monitor manual actuation electrically, and therefore cannot react discretely to a manual operation.

From a power engineering point of view, the relay is only actuated with a switching pulse if the last known relay position set by the bus has changed. As a consequence, after a one-off manual switching operation, a switch telegram received via the bus triggers no contact changeover because the switch actuator assumes that no changeover has taken place and that the correct contact position is still set.

An exception to this situation is after bus voltage failure and recovery. In both cases, the relay position is recalculated based on the parameterization and set independently of the contact position.

Device technology

Supplied state

The device is supplied with the physical address 15.15.255. The application program is preloaded.

It is therefore only necessary to load group addresses and parameters during commissioning.

However, the complete application program can be reloaded if required. Downloads may take longer after a change of application program, a discharge or an aborted download.

Download response

Depending on the PC which is used, the progress bar for the download may take up to one and a half minutes to appear, due to the complexity of the device.

Assignment of the physical address

The assignment and programming of the physical address is carried out in ETS.

The device features a Programming button for assignment of the physical device address. The red

Programming LED lights up after the button has been pushed. It switches off as soon as ETS has assigned the physical address or the Programming button is pressed again.

Cleaning

If devices become dirty they can be cleaned using a dry cloth or a cloth dampened with a soapy solution.

Corrosive agents or solutions should never be used.

Maintenance

The device is maintenance-free. No repairs should be carried out by unauthorized personnel if damage occurs, e.g. during transport and/or storage.

Commissioning

All SA/S devices and each of their outputs have the same function, with the exception of current detection.

It is thus possible, depending on the application, to freely define every output and parameterize it accordingly.

The applications feature the same appearance and the same parameter window. This significantly simplifies engineering and programming for ABB i-bus

Current detection is only integrated in types SA/S x.16.6.1.

Every Switch Actuator has its own application program with the same functions, whereby devices with current detection feature additional parameters and communication objects for the current detection.

The following operating modes are available for each output of a Switch Actuator:

Switch actuator

Heating actuator

For “normal” switching, e.g. of lighting.

The output is controlled directly via the communication object Switch . A large number of additional functions

(time, logic, safety, etc.) are possible.

For further information see:

Planning and application , p. 141

For control of heating valves, e.g. in an individual room temperature control system. A room thermostat sends a control value which the output uses to control the valve, e.g. as a 2-step control.

For further information see:

Planning and application , p. 141

Please note

With the introduction of optimized current detection, on all Switch Actuator types the nomenclature for status messages, e.g. Telegr.status switch , Telegr.RTR fault , has been converted to the current nomenclature without Telegr., e.g. Status Switch, RTR fault .

Important

Usually, the version numbers of our product names match the version number of the application program. Among our Switch Actuators there are some exceptions, e.g. the SA/S 4.16.6.1:

Product name : Switch Actuator, 4fold, 16 A, MDRC

(V1.0)

Application program : Switch 4f 16CS/ 3.0

Important

The Switch Actuator types SA/S x.16.6.1 differentiate from the predecessor types SA/S x.16.5S by new hardware and software.

While there have been few changes to the functions of the software, the hardware has been redesigned for load currents up to 20 A. Furthermore, current detection has been optimized, enhancing its accuracy by a factor of four.

To minimize programming work, with the SA/S x.16.6.1 and SA/S x.16.5.1 it is possible to copy or exchange the device's output parameters.

Please note

If the number of outputs of the target device is larger than the number of outputs of the source device, only the first outputs of the target device are written with the converted data of the source device.

The remaining outputs retain or are reset to the default values. However, the group assignments of the existing communication object do not change.

3.1.1.1.1 Summary of conversion

•

All Switch.../3.1

or 3.2

applications (SA/S x.16.y.1 with or without current detection) are interchangeable.

•

Switch...CS/2.0

applications (SA/S x.16.5S with current detection) are approved as a source.

•

The Switch 12f 16C/2.0

application (SA/S 12.16.5 12-fold device without current detection) cannot be used as a source.

•

The general rules for conversion apply (parameters in the source device that do not exist in the target device are ignored; parameters in the target device that do not exist in the source device retain their default value).

•

The Switch…6M/3.2

application is not recognized as a source by older devices. In other words, the application for the 6 A with manual operation can only be loaded onto a 6 A with manual operation.

3.1.2 Copying and exchanging parameter settings

Please note

The output copy and exchange function is integrated into all Switch Actuators.

Parameterization of devices can take a lot of time depending on the complexity of the application and the number of device outputs. To keep commissioning work to the minimum possible, using the function

Copy/Exchange channels , parameter settings of an output can be copied or exchanged to/with any output.

Optionally, the group addresses can be retained, copied or deleted in the target output.

The output copy function is particularly useful with Switch Actuators that have several outputs with the same parameter settings. For example, lighting in a room is frequently controlled in an identical manner.

In this case, the parameter settings from output X of a Switch Actuator can be copied to all other outputs or to a particular output of the Switch Actuator. Thus the parameters for this output need not be set separately, which significantly shortens commissioning time.

The exchange of parameter settings is useful e.g. should the outputs be swapped when wiring the terminals. The parameter settings of the incorrectly wired outputs can simply be exchanged, saving timeconsuming rewiring.

Transmission and switching delay time after recovery of bus voltage [2…255s]

Options: 2…255

During the transmission and switching delay, telegrams are received only. The telegrams are not processed, however, and the outputs remain unchanged. No telegrams are sent via the bus.

After the transmission and switching delay, telegrams are sent and the state of the outputs is set to correspond with the parameterization or the communication object values.

If communication objects are read during the sending and switching delay, e.g. by a visualization system, these read requests are stored, and a response is sent, after the sending and switching delay has been completed.

An initialization time of about two seconds is included in the delay time. The initialization time is the time that the processor requires to be ready to function.

How does the device react on bus voltage recovery?

After bus voltage recovery, the device always waits for the transmission delay time to elapse before sending telegrams via the bus.

Rate of telegrams

Options: not limited

1 Telegram / Second

2 Telegrams / Second





The load on the bus generated by the device can be limited by the telegram rate. This limit relates to all telegrams sent by the device.

• x* Telegrams / Second : within a second, x telegrams are sent as quickly as possible via the bus.

Please note

The device counts the number of telegrams sent within a second. As soon as the maximum number of sent telegrams is reached, no further telegrams are sent via KNX until the end of the second. The telegram counter is reset to zero, and sending is allowed again after the second has timed-out. The current communication object value is always sent at the time of transmission.

Example

Maximum number of sent telegrams = 5,

20 telegrams are ready to send. The device immediately sends 5 telegrams. The next 5 telegrams are sent after a maximum of 1 second. From this point, a further 5 telegrams are sent via KNX every second. x = 1, 2, 3, 5, 10 or 20

Send cyclical "In operation" telegram

[0...65,535s, 0 = inactive]

Options: 0…65,535

The communication object In Operation indicates that the device on the bus is working properly. This cyclic telegram can be monitored by an external device.

Please note

After bus voltage recovery, the communication object sends its value after the set sending and switching delay.

To keep the bus load to a minimum, the longest possible transmission time interval should be selected, based on the application.

3.2.3 Operating mode Switch Actuator

The Switch Actuator operating mode is used for normal switching, e.g. of lighting. The output is controlled via various logic, time and safety functions. The input signal for the function is received via communication object Switch . The Switch Actuator carries out the function independently and controls the corresponding relay.

The comprehensive range of additional functions available are described in this section.

Status response of switching state

Object "Status Switch"

Options: no only after changing always

This parameter can enable the communication object Status Switch . This contains the current switch state i.e. contact position.

• no : The contact position is updated but the status is not actively sent via the bus.

• only after changing : if the contact position changes the status is actively sent via the bus by communication object Status Switch .

SA/S | 2CDC 505 056 D0208 67

ABB i-bus

Commissioning

• always : The status of the contact position is always actively sent via the bus via communication object

Status Switch , even when a change in status has not occurred. Transmission is triggered as soon as the communication objects Switch, Threshold input or Permanent ON receive a telegram. Even a scene or a preset recall triggers transmission of the switch state. The status is also sent if logic objects

Logical connection 1 or Logical connection 2 receive a telegram. However, status is not repeated or resent due to a safety change (forced operation, priority) and this applies to all types. This can have a major effect on the bus load on a Switch Actuator with multiple outputs.

Please note

After parameterization changes or subsequently switching off the status object, the existing assignment of group addresses to the Switch communication object is lost and needs to be re-allocated.

The status value to be sent is defined using the parameter Object value switching status (Object “Status

Switch” ).

Please note

The contact position is determined by a sequence of priorities and logical connections – see Function diagram , p. 161.

The contact position can only be correctly evaluated if the switching actions occur via KNX. The SA/S cannot differentiate between manual switching and a cable break or device fault.

Object value switching status

(Object “Status Switch”)

Options: 1=closed, 0=open

0=closed, 1=open

•

1=closed, 0=open : In communication object Status Switch, the value 1 is written for a closed contact, and the value 0 for an open contact.

•

0=closed, 1=open : In communication object Status Switch the value 0 is written for a closed contact, and the value 1 for an open contact.

Value object "Switch" on bus voltage recovery

Options: not write to write with 0 to write with 1

With this parameter, the output can be influenced after bus voltage recovery. As standard the communication object Switch receives the value 0.

• not write : After bus voltage recovery, communication object Switch retains the value 0. The contact position is not re-determined.

Please note

Before the very first download (device fresh from the factory), the value before bus voltage failure is not defined. For this reason, the communication object Switch is written with 0 and the contact is open.

If opening of the contact at bus voltage recovery before the first download (installation phase) is not desired, this can be prevented by temporarily removing the KNX voltage.

• to write with 0 : The communication object Switch is written with a 0 on bus voltage recovery.

The contact position is redefined and set based on the set device parameterization.

• to write with 1 : The communication object Switch is written with a 1 on bus voltage recovery.

The contact position is redefined and set based on the set device parameterization.

Please note

Provided that no manual switching action has occurred, the communication object Status Switch indicates the correct status of the contact position independently of the value of communication object

Switch .

The Switch Actuator draws the energy for switching the contact from the bus. Depending on the type of

Switch Actuator, about 10 to 30 seconds is required after bus voltage is applied before sufficient energy is available to switch all contacts simultaneously, see Technical data from p. 9.

Depending on the set delay time in the parameter Transmission and switching delay after recovery of bus voltage in the General parameter window, the individual outputs assume the desired contact position only after this delay has elapsed. If a shorter delay time is set, the Switch Actuator will only switch the first contact when sufficient energy is stored in the Switch Actuator to immediately bring all outputs safely to the required position should another bus voltage failure occur.

Send status via object

"contact monitoring"


The send behavior of the communication object Contact monitoring can be set using this parameter. The

Contact monitoring communication object displays contact faults. An error (value 1) is displayed as soon as a current of abou t 30 mA (observe the tolerances) is detected on an open contact.

• no : The value of the communication object is always updated but not sent.

• always : The switch status is updated and always sent when there is a change of status or the contact is to be opened and is not yet open. No value is sent when closing the contact. The reset status is only sent when it is next opened.

• only after changing : A telegram is only sent if the value of communication object Contact monitoring changes. This can influence the bus load significantly, particularly for Switch Actuators with multiple outputs.

Important

The contact position can only be correctly evaluated if the switching actions occur via KNX.

The SA/S cannot differentiate between manual switching and a cable break or device fault.

Evaluation of the contact monitoring occurs about two seconds after opening the contact.

The following parameters appear when Staircase lighting is selected:

Duration of staircase lighting

Minutes

Options: 0…5…1,000

Seconds

Options: 0…59

The staircase lighting time defines how long the staircase lighting is switched on after an ON telegram. The input is made in minutes and seconds. The staircase lighting time may extend depending on the value set in the parameter Warning before end of staircase lighting .

Extending staircase lighting by multiple operation ("pumping up")

Options: no (not retriggerable) yes (retriggerable) up to max. 2 x staircase lighting time up to max. 3 x staircase lighting time up to max. 4 x staircase lighting time up to max. 5 x staircase lighting time

If a further ON telegram is received during the staircase lighting time sequence, the remaining staircase lighting time can be extended by a further period. This is possible by repeated operation of the button (“pumping up“) until the maximum parameterized number of retriggering operations is reached. The maximum time can be set to 1, 2, 3, 4 or 5 times the staircase lighting time.

Let's say the staircase lighting time has been extended by “pumping up” to the maximum time.

If some of the time has already timed out, the staircase lighting time can be re-extended to the maximum time by “pumping up”.

However the parameterized maximum time may not be exceeded.

Staircase lighting can be switched off

Options: ON with "1" and OFF with "0"

ON with "1" no action with "0"

ON with "0" or "1", switch OFF not possible

This parameter defines the telegram value used for switching the staircase lighting on and off prematurely.

•

ON with "0" or "1" switch OFF not possible : The staircase lighting function is switched on independently of the value of the incoming telegram. Premature switch off is not possible.

Please note

After enabling the Time function via communication object Disable time function , the contact position of the enabled output remains unchanged. The Time function is only triggered after the next switching telegram. However this means that if set to the option ON with "1" no action with

"0" , the output is simultaneously switched on when enabled. Switch off via the bus is thus not possible. Only after e.g. the staircase lighting function is started does the output switch off, after the staircase lighting time has elapsed.

Warning before end of staircase lighting

Options: no via object via quick switching OFF/ON via object and switching OFF/ON

Before the staircase lighting time elapse, the user can be informed of the imminent lighting switch of by a warning. If the warning time is not 0, the staircase lighting time is extended by the warning time. The warning time is not modified by “pumping up”.

• no : No warning is given, the staircase lighting switches off immediately after the staircase lighting time elapses. If the staircase lighting is ended prematurely, e.g. by a switching telegram, no warning is given.

There are two types of warning:

1. The communication object warning stair lighting is set to the value 1 when the warning time starts, and remains until it has elapsed. The communication object can be used, for example, to switch a warning light.

2. Switching the output (briefly OFF and ON again).

Both options can be used together or separately. The time duration between the OFF and ON process is about 1 second. If the warning time is not 0, the staircase lighting time is extended by the warning time.

Please note

When dealing with the warning time it is important to remember that the SA/S draws its switching energy exclusively from the KNX. Furthermore, the SA/S collects enough energy before the first switch to ensure that all outputs can safely go to the required position should the bus voltage fail. Under these conditions, only a certain number of switching actions are possible per minute: see Technical data , from p. 9.

Warning time in sec. [0...65,535] add to duration of staircase lighting

Options: 0…45…65,535

This parameter is visible if you have set a warning before the staircase lighting time ends.

The warning time must be entered in seconds. The staircase lighting time is extended by the warning time. The warning is triggered at the start of the warning time.

The warning time is not modified by “pumping up”.

Duration of staircase lighting can be changed by object

“Staircase lighting time”

Options: no yes

• yes : A 2 byte Duration of stair lighting communication object is enabled. This can be used to change the staircase lighting time via the bus. The value defines the staircase lighting time in seconds.

• no : The staircase lighting time cannot be changed via the bus.

Please note

On bus voltage failure, the staircase lighting time changed via the bus is lost and must be reset.

B By the parameterization of the communication object Switch . Whether the light is switched on or off on bus voltage recovery depends on the settings of Switch .

Restart of staircase time after end of permanent ON

Options: no yes

• no : The lighting switches off if Permanent ON is ended.

• yes : The lighting remains on and the staircase lighting time restarts.

The function of Permanent ON is controlled via the communication object value Permanent ON . If the communication object receives a telegram with the value 1, the output is switched on regardless of the value of the communication object Switch and remains switched on until the communication object

Permanent ON has the value 0.

Please note

Permanent ON only switches ON and “masks” the other functions. This means that the other functions, e.g. Staircase lighting time or “Pumping up”, continue to run in the background but do not initiate any action. After Permanent ON ends, the contact position which would result without the permanent ON function becomes active.

3.2.3.1.5 Parameter window A: Safety

All settings for the Safety function are undertaken in this parameter window.

This parameter window is visible if the parameter Enable functions "priority and safety operation" has been enabled in Parameter window A: Function , p. 71

The forced operation (a 1 or 2 bit communication object per output) or safety priority (three independent

1 bit communication objects per Switch Actuator) sets the output in a defined state which can no longer be changed as long as forced operation or safety priority is active. The parameterized reaction on bus voltage failure and recovery has a higher priority.

Enabling of the three communication objects Safety Priority x (x = 1, 2, 3) is undertaken in the General parameter window. Monitoring time and the telegram value to be monitored are set in this window.

If a telegram is not received within this monitoring time, the output will assume the safety position.

This is determined in parameter window A: Safety , described below.

In contrast to the three safety priorities, each output has a communication object Forced operation .

Forced operation can be activated or deactivated via a 1 or 2 bit communication object. Using the 2 bit communication object, the output state is defined directly via the value.

The contact position after the safety function ends can be set using the parameter Reaction when forced operation and all Safety Priority x end .

OFF

If the communication object Forced operation receives a telegram with the value 2 (binary 10), the output of the Switch Actuator is switched off and remains disabled until forced operation is switched off again.

Actuation via another communication object is not possible as long as forced operation is activated.

The state of the output at the end of forced operation can be parameterized.

Forced ON If the communication object Forced operation receives a telegram with the value 3 (binary 11), the output of the Switch Actuator is switched on and remains disabled until forced operation is switched off again.

Actuation via another communication object is not possible as long as forced operation is activated.

The state of the output at the end of forced operation can be parameterized.

Options: inactive active

• inactive : Forced operation is switched off, and the output behaves in the same way as with parameter Reaction when forced operation and all safety Priority x end .

• active : Forced operation is active again after bus voltage recovery. The contact position of the output is determined by the parameterization of Contact position if forced operation .

The threshold function facilitates the evaluation of a 1 or 2 byte communication object, Threshold input .

A switching action can be triggered as soon as the value of the communication object undershoots or overshoots a threshold value. Two independent threshold values are available. Threshold 1 can be modified via the bus.

For further information see: Threshold function , p. 159

When the threshold function is active, the Switch Actuator continues to receive switching telegrams.

In this way, the contact position determined by the threshold function can be changed, see Function diagram , p. 147. The threshold function generates a switching telegram as soon as a new threshold telegram is received and a new switching condition exists simultaneously due to undershoot or overshoot of the switching criterion.

If the parameter Send current value, transmission time [0...65,535s, 0 = not send] is also activated, the counter is reset and restarted after sending the current value.

Please note

If for example, a current change of 1 A has been selected, a current value is only sent if the load current exceeds 1 A when starting, for example, from 0 A. This means that no current value is sent (displayed) when a current of 0.9 A is flowing.

The other way around, a current value can be displayed (sent) even though no current is flowing.

Starting from 1.5 A the current is reduced to 0 A. A current value of 0.5 A is sent via the bus. Since no further 1 A current change can occur for a current value of 0, no new value is sent. The last value sent and displayed is 0.5 A.

These inaccuracies can be prevented by additional activation of the parameter Send current value, transmission time [0...65,535s, 0 = not send] or if a sufficiently small current change has been selected.

This parameter determines the contact position at which the information Threshold undershoot or

Threshold overshoot is sent.

• always : Falling below or exceeding the set current threshold value can be evaluated for both contact positions. This is only sent via KNX if the status changes. As a result, with a contact opened via KNX (current flow interrupted), a current threshold undershoot is always detected

(as an error). However, this is only sent when there is a status change.

Commissioning

• only with closed contact : Falling below or exceeding the set current threshold value can only be evaluated when the contact is closed. As a result, a current threshold undershoot is never detected (as an error) on a contact opened via KNX (current flow interrupted). The precondition for evaluation to work properly is that the contact is closed by a switch action via KNX. Manual switching is not recognized, the current threshold evaluation is not interrupted. Thus manual switching is interpreted as a circuit-breaker or load fault. The evaluation occurs in accordance with the time set in parameter Evaluation delay [0...255s] after contact closing .

• only with open contact : Falling below or exceeding the set current threshold value can only be evaluated when the contact is open. In this way, for example, you can immediately detect when a switched-off contact is inadmissibly switched on manually. Evaluation occurs about one second after opening the contact. The time is fixed for system reasons and cannot be influenced. Monitoring occurs not just once after a contact change, but rather continuously

(about once a second).

How does evaluation function?

Current value is detected in accordance with the parameterized contact position. Should it be different to the contact position parameterized on the output of the SA/S, the current value is neither detected nor evaluated. Furthermore, the current value is not recorded during the parameterized evaluation delay and therefore no comparison with the setpoint is undertaken during this period. When the evaluation delay has elapsed, the present current value is recorded and compared with the current threshold value.

The status of the current threshold value is only sent if there is a status change in comparison to the previous status value.

When only with closed contact is selected, the current is only detected with a closed contact, compared to the current threshold value, and sent if there has been a change. If the contact is opened, there is no current detection and thus no evaluation. A prerequisite is that the contact is opened by a switching telegram initiated via KNX. Manual switching is not recognized. In this case, the SA/S assumes that there is a cable break or load fault.

If current detection goes ahead, the detected current value is compared to the current threshold value, and sent if there has been a status change.

If the value dropped below the threshold before the contact was opened and is still below the threshold after the contact is closed again, the below threshold value information is not sent again as the status has not changed.

With the option always , the current is detected regardless of the contact position and continuously compared with the current threshold value. But the status of the threshold value is only sent if the status has changed.

Example

The SA/S contact is closed and the connected load fails. The undershoot of the current threshold value is detected, and the changed status is sent. The SA/S contact is subsequently opened.

The current flow is zero and still under the threshold. As the status of the current threshold value has not changed, it will not be resent.

The new status is sent only after the next setpoint overshoot.

Evaluation delay [0…255s] after contact closing


With this parameter you can ensure that brief start-up currents or current peaks caused by the switching process do not lead to an unwanted current threshold value signal. This method masks out measured values.

Only after this time has elapsed will the Status Current-Threshold be sent via the communication object of the same name , if the threshold value has changed.

Value of hysteresis current threshold 1

Options: 3/25/50

/100/200/500 mA

1/2/5 A

To avoid a continuously changing threshold value state, the current detection thresholds feature a hysteresis function. The set Value of hysteresis current threshold ensures that a current change is only registered as such if it is greater than the hysteresis value. Only then will a change of current threshold value status be sent.

Partly due to fluctuations in the electrical system and the detection accuracy of the current transformers in the Switch Actuator, 3 mA is the smallest hysteresis possible.

For further information see: Threshold   function with current detection , p. 142 and Current detection specifications , p. 44

Please note

No hysteresis is used with the option none. With a highly fluctuating current value this can often lead to frequently changing threshold results. The bus load increases unnecessarily if there is continuous status change.

On receipt of the telegram, the communication capability of the bus or the sensor (signaling device) can be monitored. If the Switch Actuator does not receive a telegram on the communication object Safety Priority 1 within a certain time (value can be parameterized), a fault is assumed and a response, as parameterized in parameter window A: Safety , is implemented. The Switch Actuator output goes into a safety state and does not process any telegrams. Only after communication object Safety Priority 1 receives a 1 or 0 again (depending on the parameterization) will incoming telegrams be processed again and the contact position changed.

Safety Priority 1 is also triggered if a telegram with the parameterizable trigger value is received.

With the exception of the reaction on bus voltage failure and recovery, the Safety Priority 1 function takes highest priority in the Switch Actuator, (see Function diagram , p. 147).

Please note

With logical connections or forced operations, modifying communication object Switch does not necessarily result in a changed contact position.


The Switch Actuator does not monitor manual actuation electrically, and therefore cannot react discretely to a manual operation.

From a power engineering point of view, the relay is only actuated with a switching pulse if the last known relay position set by the bus has changed. As a consequence, after a one-off manual switching operation, a switch telegram received via the bus triggers no contact changeover because the switch actuator assumes that no changeover has taken place and that the correct contact position is still set.

An exception to this situation is after bus voltage failure and recovery. In both cases, the relay position is recalculated based on the parameterization and set independently of the contact position.

If communication object Permanent ON is assigned the value 1, the output is switched on irrespective of the value of communication object Switch and remains switched on until Permanent ON has the value 0. After ending the permanent ON state, the state of Switch is used.

Permanent ON only switches ON and “masks” the other functions. This means that the other functions, e.g. Staircase lighting, continue to run in the background but do not initiate a switching action. When permanent ON ends , the contact position which would result without the permanent ON function becomes active. For the Staircase lighting function, the response after permanent ON can be parameterized in Parameter window A: Time , p. 76.

This communication object can be used, for example, to allow service or maintenance and cleaning personnel to initiate a permanent ON. The device receives a switch telegram via the switch object.

3.2.5 Operating mode Heating Actuator

In Heating Actuator operating mode the Switch Actuators are generally used as setting elements for electro-thermal valve drives. Room temperature can be controlled in conjunction with a room thermostat or room thermometer which controls the Switch Actuator.

Various types of control are possible, e.g. PWM, 2-point control (1 bit) or continuous control (1 byte).

Every individual output of a Switch Actuator can be controlled via a 1 bit control value. For this purpose, the Switch communication objects for the outputs have to be connected with the Control value communication objects of the room thermostats/temperature controllers.

Please note

The parameters of the room thermostat must be set to continuous 2-point control or switching 2-point control .

With so-called continuous control, a 1 byte value [0...255] is used as an input signal. This input signal is used in the Switch Actuator in accordance with the parameterizable cycle time in the ON and OFF command of the switch rela y. At 0 %, the valve is closed, and at 100 % it is fully open. Intermediate values are calculated via pulse width modulation (PWM).

For further information see: Pulse width modulation – calculation , p. 164

Please note

Electromechanical Switch Actuators, including SA/S Switch Actuators, have mechanical contacts.

On the one hand this achieves electrical isolation and very high switching capacity, on the other it is associated with switching noise and mechanical wear.

Important

When Heating Actuator operating mode is selected, the service life of the switching contacts must be considered, see Technical data , from p. 9.

This is essential if the output is used as a continuous controller.

Considering these aspects, it can be useful to use an Electronic Switch Actuator, Fan Coil Actuator or Fan

Coil Controller from the ABB i-bus

®

KNX range. These actuators do not feature electrical isolation and have a considerably smaller, but quite sufficient, switching capacity. Mechanical wear and switching noises are not an issue.

Status response of switching state

Object "Status Switch"


This parameter enables the communication object Status Switch . This contains the current switch state i.e. contact position.

• no : The contact position is updated but the status is not actively sent via the bus.

• only after changing : When the contact position changes, communication object Status Switch actively sends the status via the bus. This can have a major effect on the bus load on a Switch Actuator with multiple outputs.

• always : The status of the contact position is always actively sent via the bus via communication object

Status Switch , even when no status change has occurred. Transmission is triggered as soon as communication objects Control value (PWM) or Valve purge receive a telegram.

Please note

After parameterization changes or subsequently switching off the status object, the existing assignment of group addresses to the Switch communication object is lost and needs to be re-allocated.

The contact position is determined by a sequence of priorities and logical connections – see Function diagram , p. 161.


Object value switching status

(Object "Status Switch")

Options: 1=closed, 0=open

0=closed, 1 open

•

1=closed, 0=open: The value 1 is written to communication object Status Switch for a closed contact,

0 for an open contact.

•

0=closed, 1=open : The value 0 is written to communication object Status Switch for a closed contact,

1 for an open contact.

The reaction of the heating valve is dependent on the position of the Switch Actuator relay and the valve type (normally open or normally closed).


Options: Contact open

Contact closed

Contact unchanged

This parameter defines how the contacts and accordingly the valve drives are controlled on bus voltage failure.

For further information see: Reaction on bus voltage failure, recovery and download , p. 166

Only enough energy for a switching action is available when the bus voltage fails.

If a normally closed valve is used, a closed contact means an open valve (100 %) or a closed valve (0 %) if the contact is open.

If a normally open valve is used, a closed contact means a closed valve (100 %) or an open valve (0 %) if the contact is open.

A middle position cannot be set for the valve on bus voltage failure. It moves either to its closed (0%) or open (100%) end position.

Options: 1 bit (PWM or on-off control)

1 byte (continuous)

•

1 bit (PWM or on-off control): The room thermostat controls the heating actuator via standard switching telegrams. This enables on-off control of the control value. The 1 bit value can also originate from pulse width modulation (PWM) calculated by a room thermostat. During a malfunction when the control signal is not received by the room thermostat, the Switch Actuator will undertake an autonomous PWM calculation. The SA/S uses the parameterizable PWM cycle time for this.

•

1 byte (continuous)

: A value of 0…255 (corresponds to 0 %…100 %) is preset by the room thermostat.

This process is also known as “continuousaction control”. At 0 % the valve is closed and at 100 %, fully open. The heating actuator controls intermediate values via pulse width modulation.

Telegrams from the room thermostat are transferred to the Switch Actuator at specific intervals. If one or more of the consecutive telegrams is omitted, this may indicate a communications fault or a room thermostat malfunction.

If communication objects Switch or Control value (PWM) receive no telegrams during the period defined in this parameter, the output switches to fault mode and triggers a safety position. Fault mode ends as soon as a telegram is received as a control value.

Please note

If this parameter window is visible, the room thermostat must send the control value cyclically, otherwise no monitoring function is possible.

Planning and application

In this section you will find some tips and application examples for practical use of ABB i-bus

®

Switch

Actuators.

4.1 Current detection

The current detection feature opens many new fields of application for the Switch Actuators. The following list contains a few examples:

• Load current detection (from 20 mA)

•

Detection of significant equipment failure

•

Preventative detection of failures by continuous current monitoring

•

Recording actual operating hours

•

Signaling of maintenance and service work

•

Detection of open circuits

•

Recording switch operations per period

•

Energy and load management

•

Monitoring and signaling

Please note

Only load currents with a sine wave characteristic can be detected correctly. For other signal types, e.g. phase angle or inverse phase angle control signals, the detected current value is distorted. In this case, the measured value is meaningless.

Current values less than 20 mA are indicated as a 0 mA value via KNX. For small load currents that are just above the minimum detection threshold of 20 mA a value of 0 mA could be displayed due to inaccuracies even though a current is flowing.

The current detection and monitoring function should not be used for safety-related applications. The

Switch Actuator cannot assume the function of a circuit-breaker or RCD (earth-leakage circuit breaker).

If the load current detection is used for equipment fault detection that only causes a slight change of less than 30 mA, then mains voltage and current fluctuations due to ambient influences, e.g. temperature and natural ageing of the device play a significant role. Even when current changes are detected by the Switch Actuator, the detected changes do not necessarily mean that a device has malfunctioned.

Below are some current detection application examples described in more detail.

4.1.1 Threshold   function with current detection

The current detection function features two independent thresholds.

The detected current value will fluctuate by about 20 mA due to the necessary analog/digital conversion of the detected load current. To avoid a continuous change of the threshold value state, the thresholds for current recognition feature a hysteresis function. The width of the hysteresis band is determined by the parameterizable hysteresis threshold.

Example

Hysteresis curve, parameterization: overshoot 1 – undershoot 0

Should the upper hysteresis threshold be overshot or the lower hysteresis threshold undershot, the value of communication object Status Current-Threshold x is modified and sent via the bus.

4.1.2 Operating state displays

A Switch Actuator with current detection is designed for recording and displaying operating states of electrical loads.

The operating state is detected indirectly via the load current. If the load current exceeds a threshold, an ON telegram is sent via the bus, if the value drops below the threshold, an OFF telegram is issued.

This ON/OFF telegram can be received for example by a Universal Concentrator and displayed on the display panel.

4.1.3 Recording operating hours

With the help of current detection in the Switch Actuator and a separate meter or counter element, it is possible to record, signal and display the actual electrical operating hours of electrical loads. This function can be used in facility management or for preventative maintenance and service planning. Filter exchange in air-conditioning systems or the replacement of lamps can be optimized and planned in advance.

4.1.4 Trend analysis

Trend analysis is used to monitor the states of electrical systems over long periods and to receive early warnings of possible defects. The system operator can use this information for planning and carrying out inspections, and undertake repairs before the system fails.

Example

Should the current value change, telegrams are sent via the bus. These telegrams can be evaluated on a PC and displayed as a diagram using visualization software. Thus, changes which occur over an extended period are easily recognizable. If trend analysis is combined with logging, a defective device can be quickly and easily identified before it fails.

Current display

The Switch Actuators with current detection are not current measurement display devices. The detected current and its tolerances (see Technical data , from p. 9), can be displayed.

Using the KNX, this current value can be sent to a complex maintenance center or a simple LCD display or visualization, e.g. a panel. Further processing or display is possible from here. This makes real-time monitoring or facility management of the installation possible.

The following illustration indicates the sequence in which the functions are processed. Communication objects which lead to the same box have the same priority and are processed in the sequence in which the telegrams are received.

KNX


Example

If both communication objects Logical connection x are activated, a telegram received via communication object Switch is connected to them. The result of this action serves as the input signal for the Time function. If this is not disabled, a corresponding switch signal is generated, e.g. delay or flashing. Before the switch telegram reaches the relay, communication objects Safety Priority x and

Forced operation are checked and undertaken, if required, as a priority. Subsequently, the switching action is only dependent on the state of the bus voltage. The relay is switched if a switching action allows it.

4.2.2 Time function

The Time function can be enabled (value 0) and disabled (value 1) via the bus (1 bit communication object

Disable time function ). The output operates without a delay as long as the Time function is disabled.

Various functions can be undertaken using the Time function:

•

Staircase lighting

•

ON/OFF delay

•

Flashing

4.2.2.1 Staircase lighting

After the staircase lighting time T

ON

has elapsed, the output switches off automatically. For every telegram with the value 1 the time restarts ( retrigger function ), if the parameter Extending staircase lighting by multiple operation ("pumping up") in Parameter window A: Time , p. 76 is set to no, no pump up possible .

This corresponds with the basic response of the Staircase lighting function as long as a warning is not parameterized.

Warning

The additional Warning function enables the user to be warned in good time before the staircase lighting time elapses. The warning can be carried out by switching the output on/off briefly or by sending a communication object.

The warning time T

WARN

extends the ON phase. At the start of the warning time, the output can be briefly switched on and off and/or the communication object warning stair lighting can be written with the value 1.

After the staircase lighting time T

ON

elapses, the output is switched off briefly for the T

WARN period and communication object warning stair lighting sends a telegram . As a result, for example, half of the lighting is switched off or an LED is switched on as a warning.

The entire staircase lighting time during which the lighting is on corresponds with the time period T

ON

plus

T

WARN

.

Retriggering

Via “pumping up” – actuation of the push button several times in succession – the user can adapt the staircase lighting to current needs. The maximum duration of the staircase lighting time can be set in the parameters.

If the device receives a further ON telegram when the staircase lighting is switched on, the staircase lighting time is added to the remaining period.

The warning time does not change due to “pumping up” and is added to the extended (x-fold T

ON

) ON time.

The ON/OFF delay delays output switch-on or switch-off.

The delay time T

D1

or T

D0

starts after a switch telegram, and after it has elapsed, the output executes the switch telegram.

If a new ON telegram with the value 1 is received during the switching ON delay, the ON delay time starts again. Likewise, If a new OFF telegram with the value 0 is received during the switching OFF delay, the OFF delay time starts again.

Please note

If the device receives an OFF telegram during the switching on delay time T

D1

, an ON telegram is disregarded.

4.2.2.3 Flashing

The output can flash, i.e. switch on and off periodically.

The switch on time (T

ON

) and switch off time (T

OFF

) during flashing can be parameterized.

Please note

The contact life of the contacts should be considered and can be found in the technical data. Limiting the number of switching operations with the parameter Number of ON impulses may be useful.

Furthermore, a delay in the switching sequence may possibly be caused by the limited availability of switching energy with very frequent switching. The possible number of switching operations should be considered. Refer to the technical data in section 2.

The Logic function is always re-calculated when an object value is received.

Example GATE function

•

The GATE connection is set to disable as soon as the communication object Logical connection x receives a 0.

•

The communication object Logical connection 1 receives a 0, i.e. the GATE is disabled.

•

The output of the logical connection is 0.

•

The communication object Switch receives 0, 1, 0, 1. The output of the logic operation always remains 0.

•

The communication object Logical connection x receives a 1, i.e. the GATE is enabled. The enabling condition (value 0 or 1) can be parameterized.

•

However, the output of the logical connection is not recalculated.

Please note

The values of communication objects Logical connection 1/2 and Switch can be parameterized on bus voltage recovery.

If values are not assigned for communication objects Logical Connection 1/2 , they will be deactivated.


Please note

With the SA/S x.x.x.1 the current switch status is also sent via the communication object Status Switch if a telegram is received via communication object Logical connection x . The prerequisite is that the send reaction of the switch status (see parameter window Parameter window A: General , p. 66) is set to always .

This is not the case with the SA/S x.6.1, SA/S x.10.1 and SA/S x.16.1. The switch status is only sent if a telegram is received on the communication object Switch .

4.2.4 Preset function

A parameterizable contact position can be retrieved with the help of presets. Light scenes can therefore be implemented for example with a 1 bit communication object.

Call preset

Contact positions (preset values) can be recalled via communication objects Call preset 1/2 . A maximum of two preset values are available for each output:

Action

Recall preset 1

Recall preset 2

Telegram

Communication object Call preset 1/2 = 0

Communication object Call preset 1/2 = 1

Set preset

The current contact position is stored as a new preset value via the communication object Set preset 1/2 .

The user can, for example, adapt a light scene in this way. The presets are stored via the following values:

Action

Store preset 1

Store preset 2

Telegram

Communication object Set preset 1/2 = 0

Communication object Set preset 1/2 = 1

Special function: Restore state

A useful special function can be assigned to preset 1. It is possible to recreate the brightness levels

(states) which were present before recalling preset 2.

The following diagram clarifies this:

4.2.5

This function can be used for example after a presentation to restore the lighting to the state it was in beforehand.

Scene function

With the 8 bit scene function, the push button issues the switch actuator with the instruction to recall a scene. The scene is not stored in the push button but rather in the switch actuator. All switch actuators belong to the same group address. A single telegram is thus sufficient to recall the scene.

Along with the telegram value a scene number is sent which must correspond with the scene number in the parameters of the Switch Actuator.

156 2CDC 505 056 D0208 | SA/S

ABB i-bus



KNX


Up to 64 different scenes are managed via a single group address. The scene telegram contains the recall or store functions of a scene.

The scene function which controls multiple KNX devices is described below.

With Scene it is possible to retrieve one of 64 scenes or to connect multiple KNX devices in a scene. The scene can be retrieved or stored using a single telegram. It is a prerequisite that all the operating devices are parameterized with the same scene number.

Each KNX device involved receives the scene telegram and independently controls the scene values. Via the Switch Actuator, for example, the outputs are switched on or off, the blind actuator moves the blind to a defined position, and the DALI gateway dims its output to the pre-programmed brightness values.

Up to 64 different scenes can be managed via a single KNX group address. The following information is contained in a scene telegram:

•

Number of the scene (1…64)

•

Recall scene / store scene

For further information see: Code table, 8 bit scene , p. 171

Benefits

The Scene function on ABB i-bus

®

devices offers the following decisive advantage:

All settings to be undertaken in a scene are stored in the device. Therefore, they need not be sent via

KNX with a scene recall – all that is required is a numeric value which has been assigned to the scene.

This considerably reduces the load on the bus and prevents unnecessary telegram traffic via KNX.

A typical Scene function might be as follows and is described using the 8 bit scene telegram as an example:

The task is to implement the room lighting for a presentation with ABB i-bus

®

devices. The following devices are used in the room:

•

Switch actuator for the basis lighting

•

Blind actuator for shading

•

DG/S (DALI Gateway) for dimmable lighting

•

Example

An 8 bit scene (no. 8) comprises some lamps which are connected to two Switch Actuators and a light controller output.

Also, two blinds are integrated into the Scene function via a blind actuator. The Scene can be recalled via a single KNX telegram. The prerequisite for this is that all slaves have Scene 8 set in their devices.

After a telegram has been received, the slaves switch on their Scene number 8. The blind actuator moves the blinds to the corresponding position; the lighting assumes the predefined brightness values and contact positions defined by the Scene .

Please note

The scene numbering 1 to 64 is recalled via KNX using a telegram value 0 to 63. For corresponding scene coding see Code table, 8 bit scene , p. 171.

4.2.6 Threshold function

The Threshold function monitors a 1 or 2 byte value. As soon as a threshold is undershot or overshot, the output can be switched. The threshold values can be interpreted as hysteresis values:

Threshold values are hysteresis values

When the value exceeds the upper threshold or falls below the lower threshold, the output is switched.

Please note

If the communication object Threshold receives a value that does not overshoot or undershoot the old value, no switching action is triggered.

During the Threshold function the Switch Actuator can continue to receive telegrams that can trigger switching actions.

The communication object Switch and the functions Scene, Preset and Threshold have the same priority and are processed in the order that the telegram is received.

4.3.2 2-step control

2-step control is the simplest form of control. No control value is calculated here. The room thermostat sends a 1 via the communication object Switch if a certain temperature is exceeded and a 0 if the value drops below a certain temperature. These switch values are implemented by the SA/S.

The room thermostat hysteresis limits can be used for control stability. Use of these limits does not affect the method of operation of the Switch Actuator.

A room thermostat can use the control algorithm of a PWM control. As the room thermostat sends ON and

OFF telegrams to the SA/S, the actuator operates like a 2-step control.

4.3.3 Pulse width modulation (PWM)

Should the SA/S receive a 1 byte control value as an input signal, it can use this value with the parameterized cycle time and undertake a PWM calculation.

With PWM control, the received control value [

0…100 %] calculated in the control algorithm is converted to a pulse width modulation.

The conversion is based on a constant cycle time. For example, if the SA/S receives a control value of

20 %, then for a cycle time of 15 minutes the valve will be opened for three minutes (20 % of 15 minutes) and closed for 12 minutes (80 % of 15 minutes).

CYC the valve is set to about 40 % on. t

Please note

Pulse width modulation leads to frequent switching of the outputs. The limited number of switching operations with normal Switch Actuators should be considered! Electronic Switch Actuators should preferably be used.

4.3.5 Lifetime examination of a PWM control

If a PWM cycle time of 15 minutes has been selected, this means that 4 switching operations (switching on/off) occur each hour, 96 in a day and 3,000 in a month. This amounts to 36,000 switching operations a year. With a relay life of 10

5

switching operations, this means a Switch Actuator life of less than three years.

However, if the cycle time is set too short, e.g. three minutes, this means about 150,000 switching operations annually. This in turn means the Switch Actuator life would be less than a year.

This observation assumes an AC1 switch load (almost exclusively resistive) at rated current. If the maximum number of switching operations for a purely mechanical relay load are assumed, the life of the

Switch Actuator is extended. This has an inherent risk: the contact materials can wear prematurely and may not guarantee safe conduction.

4.4 Reaction on bus voltage failure, recovery and download


Response in the event of bus voltage failure is specified by the parameter Reaction on bus voltage failure in parameter window A: General.

This parameterization acts directly on the relay and has the highest priority in the Switch Actuator.

For further information see: Function diagram , p. 147 and Function diagram , p. 161

Before the first switching action is possible after bus voltage recovery, the SA/S will first store enough energy to ensure enough is available to immediately bring all relays safely to the required (parameterized) contact position if there is another bus voltage failure.

If the setting is Contact unchanged, the relay contact position is also unchanged on bus voltage failure, i.e. with the staircase lighting function operational, this light remains on until bus voltage recovery and until a new switch action is received.

After the contact positions are set on bus voltage recovery, the Switch Actuator remains non-functional until the bus voltage recovers.

Reaction on bus voltage recovery

The Switch Actuator draws the energy for switching the contact from the bus. After bus voltage is applied, sufficient energy to switch all contacts simultaneously is only available, depending on SA/S type, after about 10…30 seconds, see Technical data , from p. 9. Depending on the transmission and switching delay after recovery of bus voltage as set in the General parameter window, the individual outputs will only assume the contact positions that result from the function switching tree after this time. If a shorter time is set, the SA/S will only switch a contact when sufficient energy is stored in the SA/S to immediately bring all outputs safely to the required contact position if another bus voltage failure occurs.

The Switch Actuator starts operating again after about 1-2 seconds, regardless of the parameterized transmission and switching delay. This means the communication objects are set according to the programming, e.g. the timer for time delay is started. Switching or telegram transmission is only possible after the transmission and switch delay times have elapsed.

The threshold, scene and preset values set via KNX are still available after bus voltage recovery if the corresponding parameters for overwriting download are set to no . If parameterization is set to yes , the values set via the bus are overwritten with the values from ETS.

Reaction on:

Threshold

(communication object Change

Threshold value 1)


Threshold value evaluation is carried out after bus voltage recovery using the parameterized threshold value, whereby the last status threshold detected in operation is used for comparison. Should no status threshold exist before bus voltage failure, the factory-set status (hysteresis limit undershoot) is assumed.

The thresholds currently saved in the SA/S are overwritten with the values parameterized in ETS if the overwrite with download parameter is set to yes . If set to no , the values stored via KNX are retained.

Safety priorities Inactive, communication object values are set to inactive
