Parameters for device reset

The configured behaviour will be executed after every application or parameter download by the ETS. A simple download of the physical address alone or partial programming of only the group addresses has the effect that this parameter is disregarded and that the configured "Behaviour after bus voltage return" will be executed instead.

Brightness value: The DALI operating devices are set to the value specified by the "Brightness value" parameter via the DALI line after an ETS programming operation.

Switch off: The DALI operating devices are switched off by the ETS after an ETS programming operation.

No reaction: After an ETS programming operation, the gateway does not transmit any commands to the DALI operating devices. The assigned DALI operating devices show no response and remain in the brightness state that was last set. In this state, no colour temperature control or colour control is possible after an ETS programming operation of the operating devices concerned even if the devices are still switched on due to the last brightness state. In this case, the group or single device concerned must either be switched off and switched on again after the ETS programming operation or must be preset to a brightness value unequal "0%" by a new telegram. Only in this way does the gateway evaluate the state "ON" for the operating devices and permits a control of the colour temperature or colour by new commands.

As with bus/mains voltage return: In this setting, the gateway shows the same behaviour after an ETS programming operation as with a bus or mains voltage return. The behaviour is specified by the parameter "After bus/mains voltage return".

At this point, the brightness value to be set after an ETS programming operation is specified.

The selection of the configurable value is not limited at the limits by the specified minimum and maximum brightness. If brightness values lower than the minimum brightness or higher than the maximum brightness are set, the gateway sets the brightness to the configured minimum and maximum limit values.

This parameter is available only with "After ETS programming operation = brightness value".

The behaviour parameterised at this point is executed in the event of a bus or mains voltage failure (mains voltage of the gateway). If there is a voltage failure on the DALI cable (e.g. due to short-circuit, cable break, mains voltage failure on gateway), then the assigned DALI operating devices will also show the configured behaviour in the event of a bus voltage failure. This is guaranteed because the parameter setting in the DALI operating devices is applied as the "System Failure Level" for the brightness after an ETS programming operation.

Brightness value: The DALI operating devices are set to the value specified by the "Brightness value" parameter via the DALI line in the event of a bus voltage failure at the gateway, provided the mains voltage supply of the gateway is still switched on. If the mains voltage fails at the gateway, this command can no longer be issued. In this case, the DALI operating devices set themselves to the programmed system failure level corresponding to this parameter, provided their mains voltage supply is still switched on.

Switch off: The DALI operating devices are switched off via the DALI cable in the case of a bus voltage failure if the mains voltage supply of the gateway is still switched on. If the mains voltage fails at the gateway, this command can no longer be issued. Here, too, the DALI operating devices set themselves to the programmed system failure level that corresponds to this parameter, provided their mains voltage supply is still switched on.

No reaction: The gateway does not send any commands to the DALI operating devices in the event of a bus or mains voltage failure. The assigned DALI operating devices, provided their mains voltage supply is still switched on, show no response and remain in the brightness state that was last set.

At this point, the brightness value to be set in the event of a bus or mains voltage failure is specified.

The selection of the configurable value is not limited at the limits by the specified minimum and maximum brightness. If brightness values lower than the minimum brightness or higher than the maximum brightness are set, the gateway sets the brightness to the configured minimum and maximum limit values.

This parameter is available only with "at bus/mains voltage failure = brightness value".

The behaviour configured at this point is executed after the bus or mains voltage returns (mains voltage of the gateway). If mains voltage only on the connected DALI operating devices (e.g. supply from an external mains conductor) is switched on or the gateway is also switched on again and the response is configured to "no reaction", the operating devices set themselves to the brightness specified in their "Power-On level". After an ETS programming operation, this value is programmed into the operating devices by the gateway and corresponds to the setting of this parameter. In the settings "Brightness before bus/mains voltage failure" and "Activate staircase function", the command "no reaction" is programmed as a power-on level into the operating devices. In the case of all other settings, the configured commands are applied directly in the operating devices. If the mains voltage of the gateway is switched on, the device executes the parameter only after initialisation. It may occur that the DALI operating devices react more quickly after bus voltage return and set themselves to the power-on level before the gateway can transmit individual commands on the DALI line. This may result in short brightness jumps. If KNX telegrams for groups or single devices are received during the initialisation of the gateway, the device will perform the most recently specified command and not the configured behaviour after the bus voltage returns.

When using standby switch-off and the delay until start-up of the DALI devices, ensure that this parameter is configured to "Switch off". This means that the affected devices do not switch on directly when the mains voltage returns but only after they have received an appropriate DALI command from the gateway via the DALI cable.

Brightness value: The DALI operating devices are set to the value specified by the "Brightness value" parameter over the DALI line after the bus or mains voltage returns at the gateway.

Switch off: The DALI operating devices are switched off when the bus/mains voltage returns via the DALI line.

Brightness before bus/mains voltage failure: After the bus or mains voltage returns, the brightness value set most recently before the bus or mains voltage failure and saved internally on bus/mains voltage failure is tracked. An ETS programming operation of the application or the parameter resets the internally stored brightness state to "OFF".

No reaction: After the bus or mains voltage returns, the gateway does not transmit any commands to the DALI operating devices. The assigned operating devices do not respond and remain in the brightness state that was last set. In this state, no colour temperature control or colour control is possible after bus or mains voltage return even if the devices are still switched on due to the last brightness state. In this case, the group or single device concerned must either be switched off and switched on again after bus or mains voltage return or must be preset to a brightness value unequal "0%" by a new telegram. Only in this way does the gateway evaluate the state "ON" for the operating devices and permits a control of the colour temperature or colour by new commands.

Activate staircase function: The staircase function is activated - independently of the object "Staircase function - Start/Stop" - after the bus or mains voltage returns. This setting is available only when the staircase function is enabled for the affected group or single device.

At this point, the brightness value to be set after the bus or mains voltage returns is specified.

The selection of the configurable value is not limited at the limits by the specified minimum and maximum brightness. If brightness values lower than the minimum brightness or higher than the maximum brightness are set, the gateway sets the brightness to the configured minimum and maximum limit values.

This parameter is available only with "After bus/mains voltage return = brightness value".

The behaviour of the colour temperature after an ETS programming operation is permanently set to "no change". After an ETS programming operation, the gateway does not transmit any colour temperatures to the DALI operating devices. This means that the assigned DALI operating devices remain in the colour temperature most recently specified.

The behaviour of the colour temperature in case of bus voltage failure, just like the behaviour after an ETS programming operation, is permanently preset to "no change". In the case of a bus voltage failure, the gateway does not transmit any commands to the DALI operating devices. The assigned DALI operating devices remain at the colour temperature most recently set provided that the mains voltage supply of the operating devices is still guaranteed. After bus voltage failure, it is no longer possible to control the colour temperature.

The behaviour of the colour temperature after the bus or mains voltage returns is set permanently to "Colour temperature before bus/mains voltage failure". After the bus or mains voltage returns, the colour temperature set most recently before the bus/mains voltage failure by relative or absolute dimming and stored internally in the event of a bus/mains voltage failure is tracked.

The behaviour of the colour after an ETS programming operation is permanently set to "no change". After an ETS programming operation, the gateway does not transmit any colours to the DALI operating devices. This means that the assigned DALI operating devices remain in the colour most recently specified.

The behaviour of the colour in case of bus voltage failure, just like the behaviour after an ETS programming operation, is permanently preset to "no change". In the case of a bus voltage failure, the gateway does not transmit any commands to the DALI operating devices. The assigned DALI operating devices remain in the colour most recently set, provided that the mains voltage supply of the operating devices is still guaranteed.
