1 General

KNX systems provide an attractive solution that meets the most demanding residential, commercial and public buildings requirements. H igh liv ing stan dard s, com fort and safety can be easi ly comb ined w ith cos teffectiveness 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 requireme nts can be met cos t-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 ProM 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.

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 command s

• 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

• Output inversion

On Switch Actuators with current detection, SA/S x.16.6.1, each output also features the lo ad 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.

it can be found under ABB/O u t put/B in ary outp ut xf 16CS/…* (x = 2, 4, 8 or 12). The device does not support the locking function of a KNX device in ETS. If you inhibit access to all of

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 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.

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 mon itoring 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 dete c tion 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

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

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 µs.

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 Cont act or s and motor-starters –

Electromechanical contactors and motor -starters. The standard describes starters and/or contactors that were originally used primarily in ind ustrial

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 µF, 140 µF, 70 µF or 35 µF) are referred to in conjunction with fluorescent

lamp loads. This switching capacity refers to standard EN 60 669 Switches for household and simil ar fix ed electr ica l

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.

Page 41

ABB i-bus KNX

Device technology

44 2CDC 505 056 D0208 | SA/S

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 loads, 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 C-load (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, produc ing an RMS value. The factor 1/√2 is derived from the crest factor Û/U

rms

= √2 for a sinusoidal curve type.

Page 42

ABB i-bus KNX

Device technology

SA/S | 2CDC 505 056 D0208 45

For a non-sinusoidal curve type, the resulting values can diverge significantly from the real RMS value. This measurement method is used in most commercia lly 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. METRAHit 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 reasons, 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 following technical specifications apply for current detection: Detection range: 0.02…20 A Accuracy: +/- 2 % of actual current value +/- 20 mA Time constant: 300 ms Scanning rate: 320 ms Load current I

Load

AC: 0…20 A, sinusoidal

Examples

Detected current value Max. inaccuracy 300 mA +/- 26 mA 2 A +/- 60 mA

16 A +/- 340 mA 20 A +/- 420 mA

For every output, the determined current values can be represented via a 2 or 4 byte value output object. The currents are represented in mA as counter values (2 byte, DTP 7.012) or floating values (4 byte, DTP 14.019).

Page 43

ABB i-bus KNX

Device technology

46 2CDC 505 056 D0208 | SA/S

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 thresh old 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

via KNX until a constant current is indicated.

• Cause equipment failure and observe the current value IF again.

• Determine the difference in current I

= IA – IF.

• Compare the difference in current ID with the current detection tolerances. The current difference must

be significantly larger than the accuracy of the current detection (2 % of I

+/- 20 mA).

• Set the current threshold in SA/S so that it is as near as possible to the determined failure current: IA – ½ ID has proven useful.

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, regulati ons 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.

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.

SA/S | 2CDC 505 056 D0208 49

3 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



KNX Switch Actuators. 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

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

Heating actuator

For control of heating valves, e.g. in an individual room tempera t ure control system . A room thermostat s ends 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, 4-fold, 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 parameter s.

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 converte d dat a of the source d ev ice. 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 applicat ion 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 commissio ning ti me.

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.

3.2 Parameters

The Switch Actuator is parameterized using Engineering Tool Software (ETS), version ETS2 V1.3 or higher.

In ETS2/ETS3 the application program can be found under ABB/Output/Binary output/Switch xf. The following sections describe the parameters of the Switch Actuators by their parameter windows.

Parameter windows are structured dynamically so that further parameters may be enabled depending on the settings and the function.

The default values of the parameters are underlined, e.g.: Options: yes

Please note

Where information in the product manual refer s to all outputs, the description output A...X is used. 2-fold corresponds to outputs A...B, 4-fold corresponds to outputs A...D, 8-fold corresponds to outputs A...H and 12-fold corresponds to outputs A...L.

The variants with current detection feature an additional parameter page as well as additional communication objects for this function.

3.2.1 Parameter window General

Higher level parameters can be set in the General parameter window.

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.

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 telegra ms are sent via K NX 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.

Function Safety Priority 1 Function Safety Priority 2 Function Safety Priority 3

Options: inactive enabled by object value “0” enabled by object value “1”

Please note

The functions and setting options for parameters Function Safety Priority 2 and Function Safety Priority 3 are the same as those for parameter Function Safety Priority 1.

In Switch Actuator operati ng m ode there ar e three Function Safety Priority x* parameters available. For each priority, you can define your own trigger condition (enabling condition) here. With safety activation, the relevant Safety Priority x* communication object becomes visible. These communication objects relate to the entire device. However, every output can react differently to the receipt of a telegram. The reaction of the output is parameterized in parameter window X: Safety of the respective output.

*x = 1, 2 or 3

• inactive: The Safety Priority x function is not used.

Control period in seconds



[0…65,535s, 0 = inactive]

Options: 0…65,535 This parameter defines the monitoring period of the Safety Priority x function. If during this time

communication object Safety Priority x* receives a telegram with the triggering condition defined in parameter Function Saf ety Priority x, it will be triggered. Should the communication object Safety Priority x* receive a telegram that does not fulfill the trigger conditions, the control period is reset and restarted.

• 0: No monitoring is taking place. However, the Safety Priority x is triggered if communication object Safety Priority x receives a telegram with the triggering condition as defined in parameter Function Safety Priority x

*x = 1, 2 or 3

Please note

The monitoring period in the Switch Actuator should be at least twice as long as the cyclical transmission time of the sensor, so that the absence of an individual signal, e.g. due to a high bus load, does not immediately trigger an alarm.

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.

Page 65

ABB i-bus KNX

Commissioning

68 2CDC 505 056 D0208 | SA/S

• 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.

Reaction on bus voltage failure

Options: Contact open Contact closed Contact unchanged

The output can adopt a defined state on bus voltage failure with this parameter.

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 voltag e recov ery . As standar d t he 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 sw itching act ion has occurre d, the communi cat ion obje ct 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 oc cur.

Options: no yes

This parameter determines whether the preset and scene values and threshold value 1 of the output modified via the bus are overwritten in the Switch Actuator by the values set in parameter windows A: Scene, A: Preset or A: Threshold.

• yes: The values set in Parameter windows A: Scene, A: Preset or A: Threshold are transferred to the Switch Actuator when a download occurs, overwriting the existing values. Reprogramming of these values via the bus is still possible at any time.

• no: The values set in Parameter windows A: Scene, A: Preset or A: Threshold value are not transferred to the Switch Actuator when a download occurs. The values can only be changed and set via the bus.

3.2.3.1 Parameter window A: Function

In this parameter window you determine the response (reaction) of the output and can enable different functions, which makes further parameter windows available.

Reaction of output A

Options: Normally closed contact Normally open contact

This parameter determines the reaction of the output as a normally open or normally closed contact.

• Normally closed co ntact: An ON telegram (1) opens the contact and an OFF telegram (0) closes it.

• Normally open contact: An ON telegram (1) closes the contact and an OFF telegram (0) opens it.

Enable time functions "delay, staircase lighting, flashing"

Options: no yes

• no: Parameter window A: Time is not enabled for output A.

• yes: Parameter window A: Time for output A, and communication object Disable time function, are

enabled.

Using this communication object, the Time function can be enabled (telegram with value 0) or disabled (telegram with value 1) via the bus.

As long as the Time function is disabled, the output can be switched on and off only without delay via the communication object Switch. The priorities as listed in Function diagram on p. 147 still remain valid.

72 2CDC 505 056 D0208 | SA/S

Please note

The Time function is only disabled when the ongoing Time function has ended. While the output is disabled, the higher switching priorities, e.g. Safety functions, are undertaken. Enabling the Time function enables the communication object Permanent ON. The output is switched

on via this communication object. It remains switched on until communication object Permanent ON receives a telegram with the value 0.

Functions continue to operate in the background during the Permanent ON phase. The contact position at the end of the Permanent ON phase results from the functions operating in the background.

With the selection yes a new parameter appears:

Value object "Disable time function" after bus voltage recovery

Options: "1", disable time functions

"0", enable time functions

• "1", disable time functions: The Time function is disabled by a telegram with the value 1.

Please note

They can only be re-enabled via the communication object Disable time function.

• "0" enable time functions: The Time function is enabled by a telegram with the value 0.

Please note

Should the staircase light on the SA/S x.6.1.1, SA/S x.10.2.1 or SA/S x.16.2.1 be disabled while the Time function is running, the time sequence stops and the light remains ON until switched off by an OFF telegram.

On the SA/S x.16.6.1 the timing continues to the end. Only then is the Time function no longer active.

How does the staircase lighting react on bus voltage failure?

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

How does the staircase lighting react on bus voltage recovery?

Reaction on bus voltage recovery is defined by two conditions: A By the communication object Disable time function. If staircase lighting is disabled after bus

voltage recovery, it can only be switched on or off via the communication object Switch.

B By parameterization of the communication object Switch. Whether the light is switched on or

off on bus voltage recovery depends on the settings of Switch.

Send status via object "contact monitoring"

Options: no only after changing always

The send behavior of the communication object Contact monitoring can be set using this parame t er. The Contact monitoring communication object displays contact faults. An error (value 1) is displayed as soon as a current of about 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 m onitoring 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.

Time function

Options: Staircase lighting function ON/OFF delay Flashing

This parameter defines the type of Time function for each output.

• Staircase lighting function: The value that switches the staircase lightin g on and off can be parameterized. The staircase lighting time starts when the function is switched on. It is switched off immediately after the staircase lighting time ends.

Please note

Switch on means the closing of a normally open contact or opening of a normally closed contact. The staircase lighting function can also be recalled via communication object Switch, Logical

Connection x (x = 1, 2) or via a light scene recall. The staircase lighting function can be disabled by a telegram to the communication object Disable time

function. Parameterization is undertaken in parameter window Parameter window A: Function, p. 71

, with the

parameter Value object "Disable time function" on bus voltage recovery.

• ON/OFF delay: The output can be switched on or off with a delay via this function.

• Flashing: The output starts to flash as soon as communication object Switch receives the

parameterized value. The flashing period can be adjusted via the duration set for ON or OFF. At the start of the flashing period, the output is switched on with a normally open contact and off with a normally closed contact. When communication object Switch receives a new value, the flashing period will restart. Relay state is parameterizable after flashing. Flashing can be inverted when the output is used as a normally closed contact. The communication object Status Switch indicat es the c urr ent relay state during flashing.

Please note

The Flashing function can be disable d by a telegram to communi cat ion object Disable time function. Parameterization is undertaken in parameter window Parameter window A: Function, p. 71

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 lighti ng time can be re-extended to the maximum time by “pumping up”.

However the parameterized maximum time may not be exceeded.

• no (not retriggerable): The receipt of an ON telegram is ignored. The staircase lighting time continues without modification to completion.

• yes (retriggerable): New ON telegrams reset the staircase lighting time and starts to count again. This process can be repeated as often as desired using this selection.

• up to max. 2/3/4/5 x staircase lighting time: New ON telegrams extend the staircase lighting time by 2/3/4/5 times the staircase lighting time.

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 lightin g funct ion is star t ed does the outp ut switc h 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.

Page 77

ABB i-bus KNX

Commissioning

80 2CDC 505 056 D0208 | SA/S

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. The staircase lighting function that has already started is completed first. A change is applied to the staircase lighting time next time it is recalled.

• 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. Until a new value is set, the staircase lighting time set via ETS applies.

How does the staircase lighting react on bus voltage failure?

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

How does the staircase lighting react on bus voltage recovery?

Reaction on bus voltage recovery is defined by two conditions.

A By the communication object Disable time function. If staircase lighting is disabled after bus voltage

recovery, it can only be switched on or off via the communication object Switch.

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.

The following parameters appear when Flashing is selected:

The output starts to flash as soon as communication object Switch receives the parameterized value. The flashing period can be adjusted via the parameterized time duration for ON or OFF. At the start of the flashing period, the output is switched on with a normally open contact and off with a normally closed contact. When communication object Switch receives a new value, the flashing period will restart. The relay state after flashing can be parameterized. Flashing can be inverted when the output is used as a normally closed contact.

The communication object Status Switch indicates the current relay state duri ng flas hin g.

Please note

Only a certain number of switching actions are possible per minute and Switch Actuator. This means that frequent switching may cause a switching delay, see Technical data, from p. 9. The same applies directly after bus voltage recovery.

When the flashing function is selected, the service life of the switching contacts must be considered, see Technical data, from p. 9

• ON (1): Flashing starts when communication object Switch receives a telegram with the value 1. A telegram with the value 0 ends flashing.

• OFF (0): Flashing starts when communication object Switch receives a telegram with the value 0. A telegram with the value 1 ends flashing.

• always flashing, ON (1) or OFF (0): A telegram with the value 1 or 0 triggers flashing. Suspension of flashing is not possible in this case.

Time for ON: Min. [0…65,535] Time for ON: Sec. [0…59]

3.2.3.1.2 Parameter window A: Preset

Preset settings can be made in this parameter window. This parameter window is visible if Enable function "presets" has been enabled in

Parameter window A: Function, p. 71

What is a preset?

Presets are used to recall a parameterized switch value, e.g. in order to implement light scenes. In addition, the output value that is currently set can be saved as a new preset value.

The preset values can be set (stored) via the bus. In parameter window A: General you define whether the values set in ETS are transferred to the Switch Actuator with a download. This is how the values saved in the actuator are overwritten.

Two presets are available per output. Preset 1 is recalled by a telegram with the value 1, Preset 2 is recalled by a telegram with the value 0. Separate communication objects are available for recalling and for saving/setting a preset.

Preset telegrams continue to be executed when the Staircase lighting function is set. The Staircase lighting function is triggered by a preset recall (ON telegram).

Reaction on preset 1 (telegr. value 0)

Options: no reaction ON OFF restore old value before preset 2

restore parameterized value of preset 2

This parameter determines the contact position that the output assumes when preset 1 is recalled, i.e., communication object Call Preset 1/2 receives a telegram with the value 0.

The following functions can be selected as further selection options:

• no reaction: No switching action is undertaken with a preset recall. The preset is ignored. The preset is also ignored on storage via the bus, i.e., no value is saved, the preset remains inactive.

• restore old value before preset 2: The current relay contact position is stored when preset 2 is first recalled. This stored value (switch state) is retained until it is set again by the recall of preset 1. The current contact position is stored again next time preset 2 is recalled.

Example

With preset 2, the lighting in a conference room is recalled for a presentation. When the presentation is finished, the lighting is restored via preset 1 to the state it was in previously.

• restore parameterized value of preset 2: resets preset 2 to the parameterized value. This can be advisable if preset 2 can be stored via the bus, see below.

Please note

With options restore old value before pr e set 2 or restore parameterized value of preset 2, saving the

preset concerned has no effect. The saved value is not recalled, but rather the parameterized function is

undertaken.

Reaction on preset 2 (telegr. value 1)

Options: no reaction ON OFF

This parameter determines the contact position that the output assumes when preset 2 is recalled, i.e., communication object Rec all Preset 1/ 2 receives a telegram with the value 1.

At the same time, on the first call up of preset 2, the state of the output is saved so that the value before preset 2 can be restored if the setting is changed according ly .

Preset can be set via the bus

Options: no yes

This parameter enables the communication object Set preset 1/2. It is thus possible to store the current contact position as the new preset value.

Telegram value 0 saves preset 1, whereas telegram value 1 saves preset 2. If the option no reactio n, restore old value before preset 2 or restore parameterized value of preset 2 has

been selected in parameter Reaction on preset 1 (telegr. value 0), no new communication object value is saved.

Using the parameter Overwrite scene, preset and threshold value 1 with download in parameter window A: General, it is possible not to overwrite the scene values set via the bus during a download and thus to protect them.

If a mains voltage failure occurs the stored preset values are lost. They are overwritten by the parameterized default values.

All settings for the Logic function are undertaken in this parameter window. This parameter window is visible if Enable function "logic" has been enabled in

Parameter window A: Function, p. 71

The Logic function provides up to two logic objects for each output, which can be logically connected via the communication object Switch.

The logic is always re-calculated when an object value is received. First, the communication object Logical connection 1 is evaluated with communication object Switch. The result is then logically linked with communication object Lo gical conn ect ion 2.

Explanations of the Logic function can be found in Logic function, p. 153

This parameter defines the value at which communication object Logical Connection 1 disables the GATE.

While it is disabled, telegrams received on communi cati on object Switch are ignored. As long as GATE is active, the last value sent to the GATE input remains on the output's logic gate. When disabled, the value that was on the output beforehand remains.

After the GATE is enabled, this value will be retained until a new value is received.

For further information see: Function diagram, p. 147

The GATE is deactivated on bus voltage failure and remains so on bus voltage recovery.

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, descri be d 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.

SA/S | 2CDC 505 056 D0208 95

If multiple demands occur, the priority is defined as follows in accordance with the sequence in parameter window A: Safety:

• Safety Priority 1 (highest priority)

• Forced operation

• Safety Priority 2

• Safety Priority 3 (lowest priority)

With the option inactive, Safety Priority x or Forced operation and the associated communication object are not considered and are omitted from the priority sequence.

Contact position if Safety Priority 1

Options: unchanged inactive ON OFF

This parameter determines the contact position of the output if the safety condition Safety Priority 1 (setting undertaken in parameter window Parameter window General, p. 62

) has been met.

The 1 bit communication object Safety Priority 1 is used as a master for the safety position. The contact positions ON, OFF and unchanged are available.

• inactive: The state of communication object Saf ety Priority 1 has no effect on the output.

Contact position if forced operation

Options: inactive unchanged via 1 bit object on, via 1 bit object off, via 1 bit object switch position via 2 bit object

Forced operation relates to the 1 or 2 bit Forced operation communication object available on every output.

• inactive: The state of the communication object Forced operation has no effect on the output.

• unchanged (via 1 bit object), on (via 1 bit object) and off (via 1 bit object): The 1 bit communication

object Forced operation determines the contact position of the output during forced operation.

• Switch position via 2 bit object: The 2 bit Forced operation communication object is enabled. The value of the telegram sent via the 2 bit object determines the contact position, see the following table:

This parameter is only visible if forced operation is activated. Depending on whether the forced operation object is a 1 bit or 2 bit communication object, there are

two different parameterization possibilities available: 1 bit communication object: 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.

Options: calculate present contact position ON OFF unchanged

This parameter is only visible if forced operation or a Safety Priority x (x = 1, 2 or 3) function is activated. The contact position of the relay at the end of forced operation and safety priorities is defined here.

• calculate present contact posit ion: After forced operation has ended, the switch value is recalculated and immediately initiated, i.e., the output continues to operate normally in the background during forced operation, the output is not changed and is only set after safety priorities end.

• unchanged: The contact position is retained during forced operation or safety priority. The contact position only changes when a new calculated switch value is received.

3.2.3.1.6 Parameter window A: Threshold

All settings for the Threshold function are undertaken in this parameter window. This parameter window is visible if the Enable function threshold parameter has been enabled in

Parameter window A: Function, p. 71

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: Thr e shol d f uncti on, p. 159

When the threshold function is active, the Switch Actuator continues to receive switching telegrams. In this way, the contact position determi ned by the threshol d f unct ion can be change d, 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.

All settings for the Current Detection function are undertaken in this parameter window. This parameter window is visible if the Enable function "current detection" parameter has been enabled in

Parameter window A: Function, p. 71

Please note

The current detection function and associated parameter window is only visible on Switch Actuators with

current detection (SA/S x.16.6.1). It offers the same functionality in both Switch Actuator and Heating Actuator modes.

The settings in parameter window A: Current Detection determine if and how the load current of the output is evaluated. Activating current detection enables the communication object Current Value.

Communication object Current Value transfers the detected current value as a mA value via KNX. The current value is a pure sine wave normalized to an RMS value.

Datapoint type object "Current Value" [0...65,535 in mA]

Options: 2 byte counter (DTP 7.012) 4 byte float (DTP 14.019)

This parameter determines the data type (datapoint, DTP) of the communication object Current Value. A 2 byte counter (EIS 10, DPT 7.012, 1 mA per digit) or a 4 byte float value (EIS 9, DTP 14.019) can be selected.

Please note

The current detection range is designed for currents between 20 mA and 20 A.

Send current value, transmission time [0…65,535s; 0 = not send]

Options: 0 1…65,535

This parameter determines if and at which intervals the present current value is sent via communication object Current Value. The cycle time must be entered in seconds.

• 0: No current values are sent cyclically via the bus. The present current values are however continuously available in the output's Current Value communication object, and can be read out.

Send current value on change of value

Options: no 25/50/100/200/500 mA 1/2/5 A

This parameter determines that on a load change the current value is sent via the bus via the Current Value communication object. A current value is always sent via the bus if the current change is greater than the current value set in this parameter. The current value sent via the bus applies as a new reference value.

• no: No current value is sent.

The smaller the current value set, the more precisely the sent value will correspond with the actual value. Highly fluctuating current values may result in a high bus load.

If the parameter Send current value, transmission time [0...65,535s, 0 = not send] is also activate d, 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.
