Disabling function

During an active disabling function, the KNX operation of the groups or single devices is overridden and locked. Continuous light switching, for example, can also be overridden. The deactivation of the disabling function can optionally take place using an additional 1-bit acknowledgement object. This prevents the deactivation of the disabling function by the disabling object. Optionally, a 1-bit status object can also be activated.

  1. On the parameter page "DALI system... -> Configuration groups -> [x] Group name -> Enabled functions" or "DALI system... -> Configuration single devices -> [x] Device name -> Enabled functions", set the parameter "Disabling function / Forced position" to "Disabling function".
  • The disabling function is enabled. The communication object "Disabling function - Activate/ Deactivate" and the parameters of the disabling function become visible.

The parameters for configuring the disabling function are available on the parameter page "DALI system... -> Configuration groups -> [x] Group name -> Disabling function" or "DALI system... -> Configuration single devices -> [x] Device name -> Disabling function".

The behaviour at the beginning of the disabling function can be specified separately for the brightness control and optionally - if the groups and single devices have this range of functions - also for the colour temperature control and colour control.

  1. Configure the "Object polarity" parameter to the desired polarity for activating and deactivating the disabling function.
  1. Set the parameter "At beginning of brightness" to the required behaviour.
  • At the beginning of the disabling function, the configured behaviour will be executed and the bus control of the group or single device locked.
  • Switch-off: A group or single device switches off at the beginning of the disabling function.
  • Preset: The brightness specified by the "Brightness value" parameter is set at the beginning of the disabling function.
  • Memory value (brightness before last switch-off): The brightness value is set that was active before the last switch-off and stored internally in the device. This memory value is stored in a non-volatile manner in the gateway so that the value is retained after the bus or mains voltage returns. After an ETS programming operation, the memory value is predefined to "100%". This value is optionally limited by the maximum brightness.
  • No reaction: The operating devices of the disabled group or the single device do not react. The devices remain in the most recently set brightness state.
  • Flashing: The affected devices are switched on and off cyclically during disabling. The "Time for flashing of the disabling functions" is generally configured on the parameter page "DALI System... -> General". During flashing, the logical switching state is fed back as "Switched on" and the brightness value as "Switch-on brightness". A soft ON/OFF function is not executed during flashing.
  1. Set the parameter "At beginning of colour temperature" to the required behaviour.
  • At the beginning of the disabling function, the configured behaviour will be executed and the bus control of the group or single device locked.
  • Preset: The colour temperature specified by the "Colour temperature" parameter is set at the beginning of the disabling function.
  • Memory value (colour temperature before last switch-off): The colour temperature value is set that was active before the last switch-off and stored internally in the device. This memory value is stored in a non-volatile manner in the gateway so that the value is retained after the bus or mains voltage returns. After ETS programming, the memory value is predefined to "minimum colour temperature".
  • No reaction: The operating devices of the disabled group or the single device do not react. The devices remain in the colour temperature state last set.
  1. Set the parameter "At beginning of colour" to the required behaviour.
  • At the beginning of the disabling function, the configured behaviour will be executed and the bus control of the group or single device locked.
  • Preset: The colour specified by the parameter "Colour (RGB)" and optionally "White value (W)" is set at the beginning of the disabling function.
  • Memory value (colour before last switch-off): The colour is set that was active before the last switch-off and stored internally in the device. This memory value is stored in a non-volatile manner in the gateway so that the value is retained after the bus or mains voltage returns. After an ETS programming operation, the memory colour value is predefined at "#FFFFFF" and the optional white value at "#FF".
  • No reaction: The operating devices of the disabled group or the single device do not react. The devices remain in the colour state last set.

The behaviour at the end of the disabling function can also be specified separately for the brightness control and optionally also for the colour temperature control and colour control. The behaviour is influenced by the acknowledgement object.

For disabling function without acknowledgement object...

  1. Deactivate the parameter "Confirmation".
  • No additional acknowledgement object is available. The disabling function is deactivated by the disabling object according to the set polarity.

For disabling function with acknowledgement object...

  1. Activate the parameter "Acknowledgement".
  • The acknowledgement object is available. The disabling function can only be deactivated using the acknowledgement object by an "ON telegram". Telegrams to the disabling object according to the "Deactivate disabling" polarity are ignored by the gateway.

OFF telegrams to the acknowledgement object do not product a reaction.

  1. Set the parameter "At the end... brightness" to the required behaviour.
  • At the end of the disabling function, the configured behaviour will be executed and the bus control of the group or the single device enabled again.
  • Switch-off: A group or single device switches off at the end of the disabling function.
  • Track: The set state received during the disabling function or adjusted before the disabling function can be tracked at the end of the disabling with the appropriate brightness value.
  • Preset: The brightness specified by the "Brightness value" parameter is set at the end of the disabling function.
  • Memory value (brightness before last switch-off). The brightness value is set that was active before the last switch-off and stored internally in the device. This memory value is stored in a non-volatile manner in the gateway so that the value is retained after the bus or mains voltage returns. After an ETS programming operation, the memory value is predefined to "100%". This value is optionally limited by the maximum brightness.
  • No reaction: The operating devices of the disabled group or the single device do not react. The devices remain in the state most recently set by the disabling function.
  • Flashing: The affected devices are switched on and off cyclically after disabling. The flashing time is generally configured on the parameter page "DALI System... -> General". During flashing, the logical switching state is fed back as "Switched on" and the brightness value as "Switch-on brightness". A soft ON/OFF function is not executed during flashing. The flashing status remains active until another bus command is received or manual operation specifies another brightness value.
  1. Set the parameter "At the end... colour temperature" to the required behaviour.
  • At the beginning of the disabling function, the configured behaviour will be executed and the bus control of the group or single device locked.
  • Track: The set state received during the disabling function or adjusted before the disabling function can be tracked at the end of the disabling with the appropriate colour temperature value.
  • Preset: The colour temperature specified by the "Colour temperature" parameter is set at the beginning of the disabling function.
  • Memory value (colour temperature before last switch-off): The colour temperature value is set that was active before the last switch-off and stored internally in the device. This memory value is stored in a non-volatile manner in the gateway so that the value is retained after the bus or mains voltage returns. After ETS programming, the memory value is predefined to "minimum colour temperature".
  • No reaction: The operating devices of the disabled group or the single device do not react. The devices remain in the colour temperature state last set.
  1. Set the parameter "At the end... colour" to the required behaviour.
  • At the beginning of the disabling function, the configured behaviour will be executed and the bus control of the group or single device locked.
  • Track: The set state received during the disabling function or adjusted before the disabling function can be tracked at the end of the disabling with the appropriate colour value.
  • Preset: The colour specified by the parameter "Colour (RGB)" and optionally "White value (W)" is set at the beginning of the disabling function.
  • Memory value (colour before last switch-off): The colour is set that was active before the last switch-off and stored internally in the device. This memory value is stored in a non-volatile manner in the gateway so that the value is retained after the bus or mains voltage returns. After an ETS programming operation, the memory colour value is predefined at "#FFFFFF" and the optional white value at "#FF".
  • No reaction: The operating devices of the disabled group or the single device do not react. The devices remain in the colour state last set.

In the "track" setting: During disabling, the overridden functions of the gateway (switching, dimming, value specifications) continue to be processed internally in the device. Consequently, newly received KNX telegrams are evaluated and time functions are triggered as well. At the end of the disabling, the tracked states are set. A scene recall (low priority) is not tracked.

After a bus failure or mains voltage failure or programming the application or the parameters with the ETS, the disabling function is always deactivated (object value "0"). With the inverted setting ("1 = enabled / 0 = disabled"), a telegram update "0" must first be carried out after the initialisation until the disabling is activated.

When tracking blocking functions at the end of a manual operation: If a disabling function was activated via the KNX before or during temporary or permanent manual operation, the gateway always executes this higher-priority function for the affected groups and single devices at the end of the manual operation (disabling of bus operation). Only in the setting "At end of permanent manual operation = Track outputs" does the gateway perform the behaviour at the beginning of the disabling function again. Bus operation by switching, dimming, value, scene, central is then disabled.

Updates of the disabling object from "activated" to "deactivated do not produce a reaction. Exception: If the behaviour is set to "no change" at the end of a manual operation, the gateway subsequently performs active disabling functions (locking of bus operation). If a "Disabling function activated" telegram is received again in this state, the gateway carries out the behaviour at the beginning of the disabling function again.
