Helvar 478 8 Channel DALI Controller: Installation and User Guide
Power on level
Set the level each channel will go to when the unit is powered on, with DALI connected.
Note: Power-on levels for SDIM are set in the router, and not using the control panel.
Options:
Channel: 1–8;
ALL
Power on level: 0 % – 100 %;
Last
(Default in DALI mode:100 %)
Failure level
Set channel levels for situations where the DALI bus goes low, such as when it is short-circuited or the DALI PSU is turned
off.
Options:
Channel: 1–8;
ALL
Failure level:
0 % 100 %;
**** (= do not apply Failure level);
(Default: 100 %)
Override level
If the override input connection is short-circuited, e.g. by contact closure on an alarm system, all channels are set to their
override level, regardless of external control signals.
Options:
Channel: 1–8;
ALL
Override level: 0 % 100 %;
**** (= do not apply override level);
(Default: 100 %)
Minimum level
Set the minimum DALI lighting level that the channel will achieve when turned on, no matter what scene is called or level
is set.
For example, if you set a minimum level of 50 % and call scene 4 (at 25 % level), the channel output level will be 50 %.
For SDIM/DMX, the level set here is actually the switch-on level, and the channel will not turn on unless it receives a
command to go to or above this level. See ‘Switch-on level’ (below).
The minimum level is 1 % by default. If you set the minimum level to 100 %, this forces the dimming curve into switch
mode. When using SDIM or DMX control, in switch mode, the ‘Switch-on level’ will apply. When using DALI control, in
switch mode, 0 % = OFF, and 1 % or more = ‘Loads at 100 %’.
Options:
Channel: 1–8;
ALL
Minimum level: 0.1 %;
1 % – 100 %;
(Default: 0.1 %)
