4.5.2 DALI Mode Button
L-DALI without LCD display are equipped with a DALI mode button (“ON/OFF/AUTO”,
see Figure 37). It is used to manually override the dim values of the attached DALI devices
and constant light controller instances. Press it once and all DALI devices on the selected
channels are switched on (“on mode”), press it again and all DALI devices on the selected
channels are switched off (“off mode”), press it a third time and the selected channels go
back to “auto mode”.
In the “on mode” and “off mode” the dim levels of the DALI devices and constant light
controller instance cannot be changed via the CEA-709 or BACnet interface (“manual
override”). In the “auto mode” the dim level of the DALI devices is controlled via the
CEA-709 or BACnet interface respectively.
Channels are selected via the DALI Channel button (see Section 4.5.3). The current state of
a DALI channel can be determined based on the corresponding DALI Activity LED (see
Section 4.4.1.9).
The main purpose of the mode button is to test the wiring during installation of the DALI
system.
4.5.3 DALI Channel Button
L-DALI without LCD display are equipped with a DALI Channel button (“CHANNEL”,
see Figure 37). It is used to select a specific channel. All other functions which can be
performed via the DALI button interface (e.g. select DALI mode, see Section 4.5.2) are
applied only to the selected DALI channel(s).
By default all DALI channels are selected. If the DALI Channel button is pressed once the
first channel is selected and the corresponding DALI Activity LED lights up orange. Now
each time the button is pressed the next channel is selected. If the last DALI channel is
selected and the button is pressed once again, all DALI channels are selected. If no button is
pressed for more than 15 seconds, the current selection is canceled.
4.5.4 DALI Program Button
L-DALI without LCD display are equipped with a DALI Program button (“PROG”, see
Figure 37). It is used to replace a broken ballast. When the button is pressed, the L-DALI
scans the selected DALI channel for missing and unconfigured ballasts. If exactly one
missing ballast and one unconfigured ballast are found on a channel, the unconfigured
ballast is used to replace the missing ballast. That is, the unconfigured ballast is configured
with the address and the configuration parameters of the missing ballast. If multiple missing
ballasts or multiple unconfigured ballasts are found, the Web UI or LINX Configurator
software must be used to replace the missing ballast(s) (see Section 5.3.2 and 7.5.1).
During the replace operation, the DALI Activity LED of the corresponding channel lights
up orange. If the operation was successful, the LED lights up green for 0.5 seconds, if it
failed, the LED lights up red for 0.5 seconds.
Which channels are selected can be controlled via the DALI Channel button (see Section
4.5.3).
4.6 LCD Display and Jog Dial
Device models with an LCD display can also be configured to their basic settings through
jog dial navigation on the LCD UI. The main page of the LCD UI is shown in Figure 39. It
displays the device’s IP address, hostname and CPU load.
