The selected device can then independently be switched on or switched off. In addition, it is possible to
preset an absolute brightness value. When activating the "Set value" button the brightness value
selected in the drop-down menu will be transmitted to the applicable device which should immediately
accept this brightness value. The brightness value that can be set does not depend on the group
parameterization for minimum or maximum brightness. Hence, the entire brightness range is available
for the device-oriented test.
In the same way, the brightness value of the DALI device currently set can be requested by activating
the "Read-out value" button. The read-out value will be displayed in the drop-down menu above.
By activating the "Read-out device status" it is possible to have the internal device states displayed.
This permits to read-out and display the general device status (device error, e.g. internal electronic
ballast error), the lamp status (e.g. defect lamps, cable break to the lamp socket), the current switching
status, the reset status and the status of the mains voltage supply of the device.
The status information of a reset or a mains voltage failure depends on the DALI device in use. Not all
devices will track these states.
The Gateway can detect an error in the DALI line (e.g. short-circuit or interrupted line) during the
device-oriented test only if information is to be read-out by the devices (read-out of value or device
status). The plug-in will then report an error.
The commands during the device-oriented DALI test will be forwarded to the devices directly via the
DALI line. Group assignments will be ignored so that group objects during the test are not tracked
preventing differences between the objects and the actual states of the devices incorporated in the
groups.
DALI test affecting several devices
Once a DALI commissioning has been executed and the devices have been identified, these devices
can be tested for their proper functioning with the DALI test. For that purpose the devices can be
switched on or off altogether via a broadcast switching command (cf. figure 48).
Figure 48: DALI test environment for a test affecting several devices
A DALI test affecting several devices cannot detect an error in the DALI line (e.g. short-circuit or
interrupted line).
The commands during this test will be directly forwarded to the devices via the DALI line. Group
assignments will be ignored so that group objects during the test are not tracked preventing
differences between the objects and the actual states of the devices incorporated into the groups.
