Test "Devices (DALI)"

As soon as a DALI commissioning has been carried out and operating devices have been found in the course of this, these devices can be tested for correct function in the device-oriented test "Devices (DALI)". It is not necessary that the devices found have also been assigned to configured groups or single devices.

The operating device to be tested must first be selected in the "Select device" selection field. All DALI operating devices found in the course of a DALI device search - identified by the device name - are available for selection here. Only one device can be tested at a time. The selected operating device can then be switched on or off individually and independently of group or single device assignments. In addition, it is possible to specify an absolute brightness value, a colour temperature value or a colour, provided that the operating device supports this function.

When the "Set" button in the "Luminous flux" area is pressed, the brightness value selected in the selection field is transmitted as a DALI Arc-Power-Level to the corresponding operating device, which should then immediately adjust to this brightness value. The brightness value specified at this point is independent of a parameterisation for minimum or maximum brightness. The whole brightness range can thus be set in the device-orientated DALI test. Similarly, the currently set brightness value of the DALI operating device can be requested by pressing the "Read" button. The read-out value is displayed in the selection box.

When testing a DALI operating device of the device type "DT8 - Tunable White (TW)", pressing the "Set" button in the "Colour temperature" area transmits the colour temperature value selected in the selection field to the corresponding operating device. The device should then adjust itself immediately to the specified colour temperature, but only if the lamp is also switched on. The colour temperature value is independent of a configuration for the minimum or maximum colour temperature. Thus, the entire colour temperature range can also be set here in the device-orientated DALI test. Similarly, the currently set colour temperature value of the DALI operating device can be requested by pressing the "Read" button. The read-out value is displayed in the selection box.

If the DALI operating device to be tested is of the device type "DT8 - Colour Control", a test of the colour setting can be carried out. When the "Set" button in the "Colour" area is pressed, the colour value selected in the selection field is transmitted to the corresponding operating device. If the operating device corresponds to the "RGBW" colour space, the white value can be tested in addition to the colour. When a value is set, the device immediately adjusts to the specified colour, but only if the lamp is also switched on. Similarly, the currently set colour/white value of the DALI operating device can be requested by pressing the "Read" button. The read value is displayed in the selection field or in the slider of the white value.

When specifying a colour temperature or colour value, the brightness value set in the test environment for the operating device is always also transmitted to the assigned operating device. During the transmission of a colour temperature or colour with the brightness value "0 %", the operating device does not normally show any reaction.

The values read in by the "Read" function may deviate from the default values due to rounding.

Specifying or reading out a colour temperature or colour is only possible with operating devices that support the DALI device type "DT8" in either the specific "Tunable White (TW)" or "Colour Control (RGBWAF)" version. During a device search in the course of a DALI commissioning, the DCA determines the type of device supported by the operating device and only offers the settings supported by the device in the DALI test environment.

By pressing the "Read" button in the "Device status" category, it is possible to display the internal states of the selected operating device. In this way, the general device status (operating device error, e.g. internal electronic ballast error), the lamp status (e.g. defective lamp, line break to the lamp socket), the current switching status, information on whether projected brightness limit values have been violated or whether the operating device is in a fading dimming process, the reset status, information on the validity of the short address and the status of the mains voltage supply can be evaluated and displayed.

Some status information depends on the DALI operating device used. Not all devices track these states.

During the test "Devices (DALI)", the commands are transmitted to the operating devices directly via the DALI cable. No group assignments or assignments to single-addressed devices are taken into account, which means that group/device objects cannot be tracked during the test and thus differences may occur between the KNX status objects and the actual states of the operating devices.
