The LED control gear is designed for a life-time stated above under reference conditions and with a failure probability of less than 10 %.
The relation of tc to ta temperature depends also on the luminaire design.
If the measured tc temperature is approx. 5 K below tc max., ta temperature should be checked and eventually critical components
(e.g. ELCAP) measured. Detailed information on request.

•The 48 V cables should be run separately from the mains connections and
mains cables to ensure good EMC conditions.
•The 48 V DC output wiring should be kept as short as possible to ensure good
EMC.
The max. secondary cable length is 30 m (60 m circuit) till beginning
of a grounded metal track light. If track light is not grounded or made of
plastic, cable length including track light is 30 m. Inside the track light cable
length is limited by voltage drop that last LMI 48V in the track light is still
supplied with minimum 46 V.
•Secondary switching is not permitted. It is allowed to add or remove one DC/DC-LED Driver during operation.
Hot plug-in is supported for one DC/DC-LED Driver.

4.8 Dimming
Dimming range 70 mA to 100 % of nominal current
Digital control with:
Programmable parameter:
Minimum dimming level
Maximum dimming level
Default minimum = depending on nominal current level
Default maximum = 100 %
Dimming curve is adapted to the eye sensitiveness.
Dimming is realized by amplitude dimming.
5.1 Control input (DA/N, DA/L)
Digital DALI signal or switchDIM can be wired on the same terminals
(DA/N and DA/L).
The control input is non-polar for digital control signals (DALI, DSI). The control signal is not SELV. Control cable has to be installed in accordance to the
requirements of low voltage installations.
Different functions depending on each module.
5.2 switchDIM
4.9 Dimming characteristics
Integrated switchDIM function allows a direct connection of a pushbutton for
dimming and switching.
Brief push (< 0.6 s) switches LED control gear ON and OFF. The dimm level is
saved at power-down and restored at power-up.
When the pushbutton is held, LED modules are dimmed. After repush the LED
modules are dimmed in the opposite direction.
In installations with LED control gears with different dimming levels or opposite
dimming directions (e.g. after a system extension), all LED control gears can be
synchronized to 50 % dimming level by a 10 s push.
Use of pushbutton with indicator lamp is not permitted.

Dimming characteristics as seen by the human eye
The communication between the LED control gear and the DC/DC-LED Driver is
done over power line. The DALI signal will be modulated by the LED control gear
and will be sent over the 48 V DC signal to the DC/DC-LED Driver.
5.4 DC operation
The DC power supply is designed for operation on DC voltage and
pulsed DC voltage.
Behaviour in DC operation mode is the same as in AC operating mode.

6. Functions
7. Miscellaneous
6.1 Short-circuit behaviour
7.1 Isolation and electric strength testing of luminaires
In case of a short-circuit at the output the output is switched off. After restart of the
DC power supply the output will be activated again. The restart can be done via
mains reset.
Electronic devices can be damaged by high voltage. This has to be considered
during the routine testing of the luminaires in production.
According to IEC 60598-1 Annex Q (informative only!) or ENEC 303-Annex A, each
luminaire should be submitted to an isolation test with 500 V DC for 1 second. This
test voltage should be connected between the interconnected phase and neutral
terminals and the earth terminal.
The isolation resistance must be at least 2 MΩ.
6.2 No-load operation
The DC power supply will not be damaged in no-load operation.
6.3 Overload protection
If the output power range is exceeded by more than 10 % the DC power supply
gives a blinking signal to the DC/DC-LED Driver.
The DC power supply will blink 5 times, after 30 s break, it checks again, if:
•there is no overload, then the device will go in normal operation.
•there is still overload, the device will blink again 5 times.
6.4 Overtemperature protection
The DC power supply will blink 3 times, after 30 s break, it checks again, if:
•there is no overtemperature, then the device will go in normal operation.
•there is still overtemperature, then the device will blink again 3 times.
6.5 corridorFUNCTION
As an alternative, IEC 60598-1 Annex Q describes a test of the electrical strength
with 1500 V AC (or 1.414 x 1500 V DC). To avoid damage to the electronic devices this
test must not be conducted.
7.2 Conditions of use and storage
Enviromental conditions: 5 % up to max. 85 %,
not condensed
(max. 56 days/year at 85 %)
Storage temperature:
-40 °C up to max. +80 °C
The devices have to be acclimatised to the specified temperature range (ta)
before they can be operated.
7.3 Additional information
Is set in the DC/DC-LED Driver.

6.6 Light level in DC operation

Guarantee conditions at

6.7 Software / programming
No warranty if device was opened.
With appropriate software and a interface different functions can be
activated and various parameters can be configured in the LED control gear.
To do so, a DALI-USB and the software (masterCONFIGURATOR) are required.
6.8 masterCONFIGURATOR
From version 2.8:
For programming functions (power-up fading, corridorFUNCTION) and device
settings (fade time, ePowerOnLevel, DC level, etc.). For further information see
masterCONFIGURATOR manual.
