Pulse dimming installation
and operation
Introduction
With Pulse dimming it is possible to create lighting systems that can be easily switched and smoothly
dimmed from multiple control points at low cost. Pulse dimming uses standard push to make
(momentary) mains voltage switches for lighting control. The different switching and dimming
functions are initiated by pressing and holding the momentary switch for varying lengths of time. A
short press on the switch turns the connected LED drivers on or off while holding down the switch will
fade the connected LED drivers up or down.
Installation requirements for Pulse dimming control
1. Pulse dimming operates by connecting the mains voltage to the DALI input terminals.
Connecting live via a push to make switch (momentary switch) to the control terminal DA+
and the neutral to the control terminal DA-, offers the on/off function and smooth dimming
control (dim-to-dark with SOLOdrive) without any digital device.
The end-user functionality, synchronization and reset of all drivers in an installation, is
explained in the next chapter of this guide.
2. All the components connected in this line are mains rated and protected accordingto
all applicable safety requirements.
3. The DALI interface is a non-polarity control interface as is Pulse dimming. The
switched Line (Ls) and Neutral (N) can be connected to either DALI terminal.
4. DALI support is disabled while Pulse dimming is operational and can be re-enabled
with a mains reset.
5. If the lighting system is upgraded from Pulse dimming operation to DALI operation,
commissioning of the DALI system is required to ensure all DALI parameters are
properly setup.
6. In an installation using Pulse dimming, LEDcode functionality cannot be used with a
Bluetooth radio, sensor, or other LEDcode devices.
7. Emergency Lighting is not supported during Pulse dimming operation.
8. The maximum number of drivers per switch is 25.
9. All drivers and other loads are connected to the same mains phase.
10. The maximum wire length from the switch to the driver is 25 meters.

Duration
Function
1
Button push-on
60 to 640ms
Switch-on time
2
Partial fade-out
Button push-and-hold
0.64 to < 6.4s
Time during which the luminous intensity
faded from 100% to certain luminous
intensity higher than minimum level.
3
Partial fade-on
Button push-and-hold
0.64 to < 6.4s
Push-and-hold again, after partial fade-
out to maximum level (when light level
< 50%), or to minimum level (when
light level > 50%).
4
Maximum fade-out
Button push-and-hold
0.64 to 6.4s
Time during which the luminous intensity
is faded from maximum level to minimum.
5
Maximum fade-out and
remaining at minimum level
0.64 to > 6.4s
Push-and-hold > 6.4s during fade-out
remains at minimum level until button is
released.
6
Maximum fade-on
Button push-and-hold
0.64 to 6.4s
Push-and-hold again, after button-release
starts fade-on to maximum level.
7
Maximum fade-on and
remaining at maximum level
0.64 to > 6.4s
Push-and-hold again, after button-
release, starts fade-on to maximum level
and remains at maximum level until
button is released.
8
Button push-off
60 to 640ms
Switch-off time.
9
Button push-on
60 to 640ms
Switch-on time; luminous intensity same
as before switching off

A
Small delays at maximum
and minimum levels
300ms
Small delays allow user to release the
button when targeting maximum or
minimum intensity.
B
Synchronization
with long button push-
end-hold at minimum and
maximum levels
> 10s
With a push-and-hold longer than 10
seconds, all LED drivers connected to
the same push button switch will
synchronize at a uniform
(minimum/maximum) light level, when
having the same direction of fading.
This process can be applied at any
time during normal operation if any
individual driver is unsynchronized.
C
Reset
with long button push-
end-hold at minimum and
maximum levels
> 25s
With a push-and-hold longer than 25
seconds, all LED drivers connected to
the same push button switch will reset to
factory settings.
This may be required when the
direction of fading is not the same
after synchronization.
Power-up conditions:
•During power-up with mains-switch connected to DALI-input, Pulse dimming commands are
not accepted.
•During power-up with DALI control-lines connected to DALI-input, DALI-commands are
accepted.
•After power cycle: power on level will be the last light level before power cycle.
Power on level will be the last light level before power cycle.
