DALI test

Starting DALI test

The DCA of the gateway offers various options for carrying out a comprehensive test of the DALI installation. Thus, after a DALI commissioning in the DALI test, it is possible to control individual operating devices, switch them, read out or preset brightness values or colour temperature or colour values. The single device status can also be displayed. In another test environment, all projected groups (1...32) or single devices (1...64) can be switched separately, changed in brightness value or in colour temperature or colour (if supported by the control gear). In addition, it is possible to check the function of the configured scenes (1...16).

The DALI test can only be performed complete if the device, group and scene configuration in the gateway remains current after DALI commissioning or parameters are changed. For this reason, it is necessary to program the gateway with the ETS before a DALI test if changes were previously made to the device configuration . Only the "All devices (broadcast)" test can be carried out without previous DALI commissioning and without ETS programming after a change in the configuration.

If the described prerequisites are fulfilled, the "DALI Test" can be called up via the tab of the same name or the button in the welcome window of the DCA. After the call, the DALI test environment is visible in the DCA window.

The DALI test is available for each DALI system and is carried out separately. Switching between the DALI systems is possible in the test environment via the "DALI System 1" and "DALI System 2" tabs.

When configuring the "Central" addressing type, only broadcast commands (switch all operating devices) can be executed in the DALI test.

The DALI test requires a functional programming connection from the ETS to the affected gateway in the KNX installation. Before running the test, the DCA first checks whether the ETS can communicate with the gateway via the KNX programming connection (status message " Connection check active"). If this is not the case, no DALI test can be carried out. The DCA then displays a status message in the display area (A).
For an interference-free DALI test, the gateway must be connected to the KNX line and the bus and mains voltage supply must be switched on without interruption. In addition, the ETS must have a functioning communications interface to the KNX (e.g. USB or IP).

If it is not possible to establish a connection to the gateway via the KNX programming interface, the cause must be identified. Reasons for a faulty connection and the appropriate remedies are listed below:

• Cause: No functioning ETS communication interface to the KNX.
  Remedy: Check, and if necessary, setup the connection in the ETS.
• Cause: Physical address and application program not previously programmed by the ETS.
  Remedy: Exit DCA and then program the physical address and the application program with the ETS.
• Cause: KNX bus voltage at the gateway or at the ETS communication interface not connected or ready for operation.
  Remedy: Connect and switch on the bus voltage.
• Cause: Mains voltage supply on the gateway not switched on.
  Remedy: Switch on the mains supply at the gateway.

The gateway detects physical transmission errors on the DALI line (e.g. short circuit) when a test is to be carried out. The DCA then displays an error. Test access to the operating devices is only possible if the DALI system concerned is in undisturbed normal operation. An interrupted DALI line is not detected during the test.
