Status indication
The DALI gateway has a 7-segment display on the front of the device, which shows the number of the selected DALI group and the short address of the selected single device during active manual operation. In addition, further operating states of the device are signaled by the 7-segment display (broadcast mode, DALI initialisation, automatic device replacement, DALI system voltage error). The 7-segment display is switched off in normal operation of the gateway.
Other KNX actuators (e.g. dimming actuators, switching / venetian blind actuators) have a status display on the front of the device in the form of LEDs to signal the switching state of the output channels in addition to the keypad for manual operation. This LED status display can indicate the current states of modern actuators either permanently or, alternatively, temporarily.
In order for the DALI gateway to perform the "temporary status indication" function in the same way as comparable KNX actuators, the application program has the same parameters and functions as those on the "Status indication" parameter page.
The status display is either exclusively a normal display or can be supplemented by a temporary indication function. With a temporary status display, the 7-segment display always shows "--". DALI group numbers or short addresses are not indicated in the process.
- Normal indication:
The parameter "Indicate status temporarily" on the "Status indication" parameter page is deactivated. In this case, the 7-segment display only shows the number of the selected DALI group and the short address of the selected single device if a manual operation is active. In addition, the special operating states mentioned in the introduction are signalled. In normal operation, the indication remains switched off. - Temporary status indication:
The parameter "Indicate status temporarily" on the "Status indication" parameter page is activated. During temporary indication, the status indication is activated by pressing the "Manual operation" button. The display length is set in the ETS.
If manual operation is enabled in the ETS, pressing the "Manual operation" button also activates the temporary or permanent manual operation mode. The 7-segment display always remains active during manual operation. At the end of manual operation mode, the display length of the temporary status indication is restarted. The indication "--" goes out after the configured time has elapsed.
If manual operation is not enabled in the ETS, the 7-segment display only shows "--" when the "Manual operation" button is pressed in accordance with the indication duration.
If the parameter "Control via object" is activated, the "Temporary status indication" communication object is available in the ETS. This object is bidirectional and can firstly signal the status of the temporary status indication, and secondly, activate the status display. If a temporary status indication has been activated by pressing the "Manual operation" button, the object transmits the value "ON". If the object receives a telegram with the value "OFF" or "ON", the 7-segment display shows "--" in accordance with the indication duration. Manual operation is not activated in this case.
By linking the "Temporary status indication" objects between the gateway and other actuators using a common group address, the indication functions of the 7-segment display and status LED can be synchronized with one another. It is thus possible to activate the status indications of all devices in a control cabinet at the same time if manual operation is triggered on only one gateway or actuator - e.g. for service or maintenance purposes.
In addition, the "Temporary status indication" object could be controlled, for example, by a magnetic contact connected to the KNX, so that the status indications of all devices are activated by opening the control cabinet door. If the door is closed, the status indications for energy saving remain switched off.
