PCA EXCEL one4all ballasts provides eye sensitive
dimming over a wide range, from 1 % or 3 % to 100 %
and a programmed lamp start feature, which saves on
lamp wear. In digital DSI and DALI mode, various
operating parameters can be changed and stored
dynamically within the ballasts memory. In the event
of a lamp failure, the ballast can report an error mes-
sage. The integration of this information in control
networks (e.g. Lonwork based systems) means that
completely new service concepts can be realized.
switchDIM, digital DSI and digital addressable DALI
controls, universal input voltage (120277 V)
and excellent dimming performance are all standard
features of the PCA EXCEL one4all. All the standard-
ized functions such as individual programming
(64 addresses), group programming (16 groups),
scenes (16 scene values), fade time and fade rate
are, of course, available in the DALI operating mode.
PCA EXCEL one4all
Lighting control for the future
The 4th generation of digital dimmable ballasts from TridonicAtco PCA EXCEL
one4all combines three unique functions in a single device: simple switch control
using switchDIM, the tried and tested flexible system using digital DSI or individually
programmable solutions using digital DALI. PCA EXCEL one4all adapts easily and
automatically to the relevant lighting management solution.
PCA EXCEL one4all communicates with the relevant control
system via two control wires regardless of whether you are
using the switchDIM, DSI or DALI system. The wiring is always
the same and the device recognizes the correct control signal
automatically and makes the necessary intelligent adjustments.
Thus the PCA EXCEL one4all guarantees extraordinary flexibility
and the capability for expansion. 3

The concept for innovative digital lighting solutions
Digital dimmable ballasts, digital lighting control sys-
tems and software for virtually all current and future
standards. In addition to TridonicAtcos digital control
components, Lonworks, DMX512 and EIB converter
modules are available to integrate digital PCA EXCEL
one4all ballasts into innovative lighting management
systems.
The PCA EXCEL one4all digital ballast provides dim-
ming solutions for the future.
The fourth generation of digital PCA EXCEL one4all
ballasts from TridonicAtco was developed after ten
years experience in the field of digital lighting solutions,
and millions of installed digital dimmable ballasts. It
gives the user a range of dimming solutions for the
T5 high output and high efficiency lamps, T8, BIAX
and CFL lamps; tried and tested, simple single pole
momentary switch controls with switchDIM, flexible
systems with DSI (digital serial interface, licence free
protocol supported by many controls companies
globally) and individually addressable solutions with
DALI (digital addressable lighting interface) the new
standardized interface protocol.
The motto for the series of PCA EXCEL one4all digital
dimmable ballasts is lighting control for the future,
which describes it perfectly.

PCA EXCEL one4all
combines three unique control features
switchDIM
Digital tunning for your light switch
switchDIM offers the most simple and cost-effective
possibility to switch and control TridonicAtco dimmable
ballasts. All you need is a standard momentary switch
and a dimmable ballast from TridonicAtco.
As conventional as this solution appears, when it
comes to functionality, with switchDIM there is no
need to compromise. Advantages such as control
from several remote-points, powerless switching via
control-wire are just some of the features.
DSI technology
The digital DSI signal is used for communication between
DSI control modules and digital dimmable DSI control devices.
The dimming commands consist of 8-bit information, which
corresponds to a precise dimmed value.
Economical dimming with finger tip control
Cost effective dimming and switching
Multi point control
Power-free switching
Polarity free wiring
Eye sensitive dimming characteristics
DSI
A proven technology. Millions in use
TridonicAtcos digital DSI-protocol (Digital Serial Interface) stands
for precise, interference free and well proven control technology.
With DSI, TridonicAtco built the basis for the now standardized
DALI-protocol.
switchDIM technology
The switchDIM control-signal corresponds to the
line voltage. Depending on how long the connected
momentary switch is pressed the PCA EXCEL one4all
interpretes this signal either as a dimming or a
switching command. 5

All luminaires receive precisely the same interference free
digital signal and therefore the same dimming value
Polarity-free control lines make wiring easier and
thus eliminate a source of error
Simple wiring class I or class II
Status information can be obtained by guerying
the DALI devices
Programmable parameters (min-, max-level, DC-level)
Individual addresses up to 64 DALI devices
16 freely definable lighting groups and 16 freely
definable lighting scenes
Additional programmable parameters
(fade rate and fade time)
DALI
What is DALI?
The DALI interface standard is a protocol for digital
communication between lighting control devices. DALI
enables 64 control devices to be addressed individually
and freely divided into 16 lighting groups and 16 light-
ing scenes. TridonicAtco has developed the DALI stan-
dard in conjunction with other leading ballasts manu-
facturers. This unified standard guarantees compati-
bility and provides for the future expansion of lighting
control.
Technical specification for a DALI line:
DALI voltage 9.522.4 V DC
DALI control current 250 mA max.
Data transfer rate 1 200 baud
Maximum single line length 300 m (at 1.5 mm
2
)
Possible to run power and control wires together
in the same line or conduit
Different wiring options (star, series and combined
networking)
The DALI control wires to the ballasts, along with those from the
control devices, which could be powered by the DALI control line,
can be run parallel to the mains or within the same conduit as the
mains. Identification of the DALI pair is not as critical as analog
circuits as the DALI control signal has no polarity. The functional
assignment of luminaires to lighting groups (with PCA EXCEL one4all)
and to the control switches is not defined until after installation,
guaranteeing maximum design freedom and flexibility even after
commissioning.
DALI technology
The DALI protocol consists of 19 bits of data that al-
lows up to 64 devices or luminaires to be individually
addressed as well as providing status information
and a variety of adjustable parameters (fade time,
fade rate ) etc.
Advantages of digital DALI/DSI systems:
DSI and DALI features
Additional DALI features 6
