KNX system
devices, actuators,
sensors
Depending on the parameterisation, the actuator can be used as a
switching actuator or a blind actuator. Mixed configurations of
switching and blind actuators are also possible. For the blind
actuator function, two neighbouring relay outputs are combined to
form one blind output.
Features
- Blind or switching operation can be parametrised. In blind
operation, the adjacent outputs (A1/A2, A3/A4...) are combined
into one blind output. Mixed operation at one actuator (e.g. A1 &
A2 blind, A3 & A4 blind, A5 switching, A6 switching ...) is
possible.
- Up to 8 independent logic functions for implementing simple or
complex logical operations.
- Actively transmitting feedback or status messages can be
delayed globally after a bus voltage recovery or ETS
programming operation.
- Manual operation of the outputs independent of KNX with
intelligent LED status displays for saving energy.
- Bistable relay.
- Supply from KNX bus, no additional power supply required.
- Simplified terminal connection (no terminal overlapping).
Blind functions
- Operating mode can be parametrised: Control of slat blinds, roller
shutters, awnings, skylights or ventilation flaps.
- Separately parameterisable movement times with movement time
extension for movements into the upper end position.
- For slat blinds, a slat movement time can be parametrised
independently.
- Switchover time for change of direction and times for short and
long-term operation (Step, Move) can be set.
- Reaction on bus voltage recovery and after an ETS programming
operation can be set for each output.
- Central control of all blind outputs via up to 6 long-term objects
possible (UP, DOWN, permanently UP, permanently DOWN).
- Feedback on the curtain or slat position. In addition, feedback on
an invalid curtain position or a drive movement is possible. Active
(send to the bus in case of change or cyclically) or passive (object
can be read out) feedback functions.
- Assignments of up to 5 different safety functions (3 wind alarms,
1 rain alarm, 1 frost alarm), or with cyclical monitoring. The
safety functions (objects, cycle times, priority) are created in a
device-based manner for all outputs. An assignment of individual
outputs to the safety functions and the safety reactions can be
parametrised based on the channel.
- Comprehensive sun protection function with fixed and variable
curtain or slat positions at the beginning or end of the function
can be activated separately for each output. Including dynamic
slat offset for slat blinds. Also with extended sun protection for
integration in more complex shading control systems (has
separate automatic and blocking objects). Optionally also with
heating/cooling automatic and presence function.
- Cloth tightening function for awnings.
- Extended blocking function with acknowledgement option.
- Ventilation function for windows with window contacts.
- Intelligent teaching function for curtain movement.
- Forced setting function or blocking function can be implemented
for each blind output.
- Up to 64 internal scenes can be parametrised per output.
- Scene memory function: Additional visual feedback.
- Extended scene retrieval (toggling of scenes).
Switching functions
- Independent switching of the switching outputs.
- NO contact or NC contact operation.
- Central switching function via up to 6 switch objects (ON, OFF,
permanently ON, permanently OFF) and collective feedback.
- Feedback on switching: Active or passive feedback function.
- Reaction to bus voltage failure or bus voltage recovery and after
an ETS programming operation can be set for each output.
- Logical individual linking function for each output.
- Blocking function can be parametrised for each channel.
Alternative separate forced setting function for each output.
- Extended blocking function with acknowledgement option.
- Time functions (switch-on and switch-off delay, staircase light
function – also with advance warning function).
- Can be integrated into light scenes: Up to 64 internal scenes can
be parametrised per output.
- Scene memory function: Additional visual feedback.
- Extended scene retrieval (toggling of scenes).
- Elapsed operating time meter can be activated individually for
each output.
- Input monitoring for cyclic updating of the switching object with
safety position.
Logic functions
- The device has 8 internal logic functions.
- Logic gate (AND, OR, exclusive AND, exclusive OR, each with up
to 4 inputs).
- 1-bit to 1-byte converter with input filter, blocking object and
specification of output values.
- Blocking element with filter and time functions and blocking
object.
- Comparator for values with 9 different input data formats and
many comparison operations.
- Limit value switch with hysteresis with upper and lower threshold
values for 9 different input data formats. Including specification
of the 1-bit output values.
- The logic functions have their own KNX communication objects
and can process telegrams from the actuator or other bus
devices.
