EIB / KNX installation bus.

All the modules have two outputs each. The Switch Actuator Module SA/M

2.6.1 switches via relay outputs while the Electronic Switch Actuator

Modules switch via noise-free, wear-resistant electronic semiconductor

components.

SA/M 2.6.1 and ES/M 2.230.1 are automatically connected to the incoming

supply when they are snapped into the Room Controller Basis Device. The

ES/M 2.24.1 is supplied via two terminals with 24 V DC.

On the output side, the devices have screw terminals with plug-in

connection.

The comprehensive functionality is defined by programming the Room

Controller Basis Device with the EIB Tool Software (ETS2 V1.2a or higher).

It is almost identical for all three devices.

3 Application and

planning

3.1 The three operating

modes

It is possible to choose between three operating modes for each output:

1. Switch actuator

This function is used for normal switching e.g. of lighting. The output is

controlled directly via the object “Switch”. A large number of additional

functions are possible. See under section 3.2 for further explanations.

2. Heating actuator

In this function, the output is used to control 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 PWM or

2-step control). See under section 3.3 for further explanations.

3. Fan coil control

This function is used to control a fan coil unit for air conditioning in a

room e.g. in an individual room temperature control system.

The function is as follows: An external room thermostat determines the

setpoint value (0…255). The fan speed and the setpoint value of the fan

coil unit are to be controlled depending on this setpoint value. Several

outputs are required for control and the output therefore controls further

outputs (“Slaves”) as a “Master” via the bus. The master-output itself

controls fan speed 1. See under section 3.4 for further explanations.

Once the staircase lighting time T

ON

has elapsed, the output automatically

switches off again. With each “1” telegram, the time restarts (“retrigger

function”).

A 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 an object.

Output

The output is switched off briefly for the period “T

” before the staircase

lighting time “T

” elapses and the object “Warning stairc. lighting” is sent.

Push button LEDs for example can flash to indicate a warning.

With pumping, the user can adapt the staircase lighting time to the current

requirements by pressing the push button several times in succession. The

maximum duration of the staircase lighting time can be set in the

parameters.

Output

If the device receives a further ON command when the staircase lighting is

switched on, the staircase lighting time is added to the remaining period. In

this case, the time does not restart (no retrigger).

Application: Lighting control on staircases, monitoring of telegrams

starts. Once it has

elapsed, the output carries out the switching command.

Note: If the device receives an OFF command during the ON delay

period T

D1

, the ON command is rejected.

Application: e.g. dynamic lightscene, in which luminaires are connected in

sequence

Flashing

The output can flash by switching on and off periodically.

Note: Please note that the maximum number of switching operations

is limited for the Switch Actuator Module SA/M 2.6.1. The

number of switching operations is unlimited for the Electronic

Switch Actuator Module.

3.2.2 Logic

With the “Logic” function, it is possible to link the switching of the output with

certain conditions. Two logic objects are available:

Output

The object “Switch” is only let through

Example shown here:

Disable if “OFF (0)”

The logic function is recalculated each time an object value is received.

Example: The gate function is parameterised with “Disable if OFF (0)”.

The logic object has the value “0”.

The object “Switch” receives the value “1”

 No reaction of the output.

3.2.3 Presets

A parameterisable switching state can be retrieved with the help of presets.

Lightscenes can therefore be implemented for example.

Fig. 1: Controlling light scenes via presets

Switching states (“preset values”) can be retrieved via the object “Call preset

Retrieve preset1 Object “Call preset 1/2” = 0

button action

Actuator 1 Actuator 2 Actuator 3

Set preset

Fig. 2: Storing the current output state as the new preset value

The current switching state is stored as a new preset value via the object

“Set preset …”. The user can thus adapt a lightscene for example. The

presets are stored via the following values:

Action Telegram

Store preset1 Object “Set preset 1/2” = 0

Store preset2 Object “Set preset 1/2” = 1

Store preset3 Object “Set preset 3/4” = 0

Store preset4 Object “Set preset 3/4” = 1

Special function: Restore state

A useful special function can also be assigned to preset1 and preset3, which

is used to recreate the brightness level which was present before retrieving

preset2 or preset4. The following diagram clarifies this:

Application and planning

This function can be used for example after a presentation to restore the

lighting to the state it was in beforehand.

3.2.4 8-bit scene

Short push

button action

Actuator 1 Actuator 2 Actuator 3

OFF ON OFF

Retrieve scene no. <xx>

Fig. 4: Retrieve scene, 8-bit scene

In the 8-bit scene, the push button gives the actuator the instruction to

retrieve a scene. The scene is not stored in the push button but in the

actuator. All the actuators are addressed via the same group address. A

single telegram is sufficient to retrieve the scene.

A scene number is sent in the telegram value which must match the scene

number in the parameters of the actuator.

After a long push button action (for example), the actuators receive a save

command which causes them to store the current value issued by the

actuator as a new scene value.

Up to 64 different scenes are managed via a single group address. An 8-bit

scene telegram contains the following information:

- Number of the scene (1...64)

- Retrieve scene / store scene

3.2.5 Threshold function

The threshold function monitors a 1-byte or 2-byte value. As soon as this

value exceeds or falls below a threshold value, the output can be switched.

The threshold values can be interpreted as hysteresis values:

Threshold values are hysteresis values

Output

Object “Threshold

value”

ON OFF

Upper threshold

Lower threshold

When the value exceeds the upper threshold or falls below the lower

threshold, the output is switched.

When the value exceeds or falls below any threshold value, the output is

switched.

Note: If the object “Threshold value” receives a value which does not

exceed or fall below any of the threshold values compared to

the old value, no switching operations are triggered.

Example: On receipt of a “Logical connection” object, the linking logic is

when the staircase lighting function is active, this can result in

the staircase lighting being switched on.

The forced operation has the highest priority as it is evaluated last of all the

functions.

Application and planning

3.3 Operating mode:

“Heating actuator”The

“Heating actuator” function is normally used to control an electrothermal

valve drive. The output receives its control value from a room thermostat.

The electrothermal valve drive can be triggered via two-step control or pulse

width modulation. When pulse width modulation is used, the control is

carried out via a variable mark-to-space ratio. The following example clarifies

this:

CYC

Fig. 6: Pulse width modulation (example)

During t

ON

, the valve is triggered with OPEN (“ON phase”). During t

OFF

the

valve is triggered with CLOSE (“OFF phase”). Due to t

ON

= 0.4 x T

CYC

, the

valve is set at approx. 40%. T

CYC

is the so-called PWM cycle time for

continuous control.

Important: A pulse width modulation leads to frequent switching of the

outputs. Consider the limited number of switching cycles for

standard switch actuators! The use of electronic switch

actuators is preferable in each case.
