KNX switching actuator 2-gang / blind actuator 1-gang 16 A with 3-gang binary input

Features

Inputs

• Depending on the ETS parameterisation in the application for switches, buttons or contacts, inputs 1 and 2 either act internally on the relay output or separately on the KNX. Input 3 always acts on the KNX.
• Functions for the inputs when acting on the KNX (switching, dimming, blind, value transmitter, scene auxiliary unit, 2-channel operation, controller auxiliary unit, no function).
• Switching: Command for closing and opening of the contact adjustable (no reaction, ON, OFF, TOGGLE).
• Dimming: Dimming of brightness and/or colour temperature. Command for closing the contact, time between switching and dimming, dimming in different steps, telegram repetition in case of long signal at the input, and sending of a stop telegram at the end of the dimming process all configurable.
• Blinds: Command for closing the contact and the operating concept can be parameterised. Times for short and long signal at input and slat adjustment are adjustable.
• Value transmitter: Functionality as 1-byte, 2-byte, 3-byte or 6-byte value transmitter including colour temperature and colour value transmitter possible. Individually configurable values. Value adjustment is optionally possible with a long signal at the input (not with the 6-byte value transmitter).
• Scene auxiliary unit: Mode of operation (with or without memory function) and the scene number are adjustable.
• 2-channel operation: When the contact at the input closes, up to two telegrams can be sent out on the KNX. Operating concept adjustable (only channel 1 or channel 2/both channels). The mode of operation of the channels (1-bit, 1-byte, 2-byte, 3-byte, 6-byte) can be configured separately.
• Controller auxiliary unit: Mode of operation (operating mode switching, forced operating mode switching, presence function and target value adjustment) configurable.
• Disabling of all or individual inputs via a 1-bit object possible. Polarity of the blocking object, behaviour at the beginning and end of blocking, and behaviour during an active blocking can be adjusted.

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.
• Blind or switching operation can be parametrised. In blind operation, both outputs (A1/A2) are combined into one blind output.
• Device has three inputs with a common reference potential.
• Read-in of switching states of installation switches or buttons and other zero-voltage contacts at inputs 1 to 3.
• Signal analysis of dew and leakage sensors (see accessories) at inputs 1 to 3.
• Recording of temperature values via remote sensors (see accessories) at input 3.
• Up to 8 independent logic functions for implementing simple or complex logical operations.
• Actively transmitting feedback or status messages can be delayed after a bus voltage recovery or ETS programming mode.
• Bistable relay.

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 in case of bus voltage recovery can be set following an ETS programming process.
• Central control 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 five different safety functions (3 wind alarms, 1 rain alarm, 1 frost alarm), with cyclical monitoring as an option.
• Comprehensive sun protection function with fixed and variable curtain or slat positions at the beginning or end of the function can be activated. 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 automatic heating/cooling and presence function.
• Fabric tensioning 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.
• Up to 64 internal scenes can be parametrised.
• 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).
• Feedback on switching: Active or passive feedback function.
• Reaction in case of bus voltage failure or bus voltage recovery can be set following an ETS programming process.
• 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.
