Luminaire

>100 mm

>20 mm

>20 mm

3.6 Hot plug-in

Hot plug-in is not supported due to residual output voltage of > 0 V.
If a LED load is connected the device has to be restarted before the output will
be activated again.
This can be done via mains reset or via interface (DALI, DSI, switchDIM).

3.7 Earth connection

The earth connection is conducted as protection earth (PE). The LED Driver
can be earthed via earth terminal. If the LED Driver will be earthed,
protection earth (PE) has to be used. There is no earth connection required
for the functionality of the LED Driver.
Earth connection is recommended to improve following behaviour:

• Electromagnetic interferences (EMI)

• LED glowing at stand-by

• Transmission of mains transients to the LED output

In general it is recommended to earth the LED Driver if the LED module is
mounted on earthed luminaire parts respectively heat sinks and thereby
representing a high capacity against earth.

3.8 I-SELECT 2 resistors connected via cable

For details see:

http://www.tridonic.com/com/en/download/technical/LCA_PRE_LC_EXC_ProductManual_en.pdf.

3.5 Wiring guidelines

• Run the secondary lines separately from the mains connections and lines
to achieve good EMC performance.

• The max. secondary cable length is 2 m (4 m circuit), this applies for LED

output as well as for I-SELECT 2.

• For good EMC performance, keep the LED wiring as short as possible.

• Secondary switching is not permitted.

• The LED Driver has no inverse-polarity protection on the secondary side.

Wrong polarity can damage LED modules with no inverse-polarity protection.

• Wrong wiring of the LED Driver can lead to malfunction or irreparable

damage.

• Through wiring of mains is for connecting additional LED Driver only.

Max. permanent current of 16 A may not be exceeded.

• To avoid the damage of the Driver, the wiring must be protected against

short circuits to earth (sharp edged metal parts, metal cable clips, louver,
etc.).

Make sure that the LED Driver is operated within the given window under all
operating conditions. Special attention needs to be paid at dimming and DC
emergency operation as the forward voltage of the connected LED modules
varies with the dimming level, due to the implemented amplitude dimming
technology. Coming below the specified minimum output voltage of the
LED Driver may cause the device to shut-down.

Minimum dimming level
Maximum dimming level

Default minimum = 1 %

5.2 switchDIM

Integrated switchDIM function allows a direct connection of a pushbutton for
dimming and switching.
Brief push (< 0.6 s) switches LED Driver 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 Drivers with different dimming levels or opposite
dimming directions (e.g. after a system extension), all LED Drivers can be
synchronized to 50 % dimming level by a 10 s push.
Use of pushbutton with indicator lamp is not permitted.

Programmable range 1 % ≤ MIN ≤ 100 %
Default maximum = 100 %
Programmable range 100 % ≥ MAX ≥ 1 %

Dimming curve is adapted to the eye sensitiveness.
Dimming is realized by amplitude dimming.

5.3 proportionSWITCH

A conventional pushbutton can be used to control the system via
proportionSWITCH.
Use of pushbutton with indicator lamp is not permitted.
If the device is controlled via DALI/DSI, proportionSWITCH is not available.

4.8 Dimming characteristics

For control via a pushbutton different settings can be made:

• Short press: Setting of 5 pre-defined light level (variable for each channel
for direct and indirect applications).
10 scens could be max. programmed.

DALI

• Long press (> 1 s): Stepless setting of dimming level.
Both channels running in opposite direction.

DSI

After completition the dimming direction of both channels will be
inverted.

• These values can be changed via masterCONFIGURATOR.

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.

6. Functions

6.1 Function: adjustable current

The output current of the LED Driver can be adjusted in a certain range.
For adjustment there are two options available.

Option 1: DALI
Adjustment is done by masterCONFIGURATOR (see masterCONFIGURATOR
documentation).
Adjustment can be done for each channel individually.

Option 2: I-SELECT 2
By inserting a suitable resistor into the I-SELECT 2 interface, the current
value can be adjusted. The relationship between output current and resistor
value can be found in the chapter “Accessories I-SELECT 2 Plugs”.

Please note that the resistor values for I-SELECT 2 are not compa­tible with I-SELECT (generation 1). Installation of an incorrect resis­tor may cause irreparable damage to the LED module(s).
The I-SELECT 2 adjustment will be taken for all channels.

Resistors for the main output current values can be ordered from Tridonic
(see accessories).

The priority for current adjustment methods is DALI (highest priority),
I-SELECT 2 (lowest priority).

6.2 Short-circuit behaviour

In case of a short-circuit at the LED output the LED output is switched off.
After restart of the LED Driver the output will be activated again.
The restart can either be done via mains reset or via interface (DALI, DSI,
switchDIM).

6.3 No-load operation

The LED Driver will not be damaged in no-load operation. The output will be
deactivated and is therefore free of voltage. If a LED load is connected the
device has to be restarted before the output will be activated again.

6.4 Overload protection

If the output voltage range is exceeded the LED Driver turns off the LED
output. After restart of the LED Driver the output will be activated again.
The restart can either be done via mains reset or via interface (DALI, DSI,
switchDIM).

6.5 Overtemperature protection

The LED Driver is protected against temporary thermal overheating.
If the temperature limit is exceeded the output current of the LED module(s)
is reduced. The temperature protection is activated above tc max.
The activation temperature differs depending on the LED load.
On DC operation this function is deactivated to fulfill emergency
requirements.

6.6 corridorFUNCTION

The corridorFUNCTION can be programmed in two different ways.
To program the corridorFUNCTION by means of software a DALI-USB interface
is needed in combination with a DALI PS. The software can be the
masterCONFIGURATOR.
To activate the corridorFUNCTION without using software a voltage of 230 V
has to be applied for five minutes at the switchDIM connection.
The unit will then switch automatically to the corridorFUNCTION.

Note:
If the corridorFUNCTION is wrongly activated in a switchDIM system (for
example a switch is used instead of pushbutton), there is the option of installing
a pushbutton and deactivating the corridorFUNCTION mode by five short
pushes of the button within three seconds.

switchDIM and corridorFUNCTION are very simple tools for controlling gears
with conventional pushbuttons or motion sensors.
To ensure correct operation a sinusoidal mains voltage with a frequency of
50 Hz or 60 Hz is required at the control input.
Special attention must be paid to achieving clear zero crossings. Serious
mains faults may impair the operation of switchDIM and corridorFUNCTION.

6.7 Constant light output (CLO)

The luminous flux of a LED decreases constantly over the lifetime.
The CLO function ensures that the emitted luminous flux remains stable.
For that purpose the LED current will increase continuously over the LED
lifetime. In masterCONFIGURATOR it is possible to select a start value
(in percent) and an expected lifetime.
The LED Driver adjusts the current afterwards automatically.

6.8 Power-up/-down fading

The power-up/-down function offers the opportunity to modify the on-/off
behavior. The time for fading on or off can be adjusted in a range of 0.2 to
16 seconds. According to this value, the device dims either from 0 % up to
the power-on level or from the current set dim level down to 0 %.
This feature applies while operating via switchDIM and when switching the
mains voltage on or off.
By factory default no fading time is set (= 0 seconds).

6.9 Light level in DC operation

The LED Driver is designed to operate on DC voltage and pulsed DC voltage.
For a reliable operation, make sure that also in DC emergency operation the
LED Driver is run within the specified conditions as stated in chapter
“4.1 operating window”.

Light output level in DC operation: programmable 1 – 100 % (EOFi = 0.13).
Programming by DALI.
In DC operation dimming mode can be activated.

The voltage-dependent input current of Driver incl. LED module is
depending on the used load.

The voltage-dependent no-load current of Driver (without or defect LED
module) is for:
AC: 22 mA (at 230 V, 50 Hz)
DC: 6 – 10 mA (at 275 – 186 V, 0 Hz)

6.10 Intelligent Voltage Guard

Intelligent Voltage Guard is the name of the electronic monitoring of the
mains voltage. It immediately shows if the mains voltage rises above certain
thresholds. Measures can then be taken quickly to prevent damage to the
LED Driver.

• If the mains voltage rises above approx. 280 Vrms (voltage depends on the
LED Driver type), the LED light starts flashing on and off.

• To avoid a damage of the LED Driver the mains supply has to be switched
off at this signal.

6.11 Software / programming

With appropriate software and an interface different functions can be
activated and various parameters can be configured in the LED Driver.
To do so, a DALI-USB and the software (masterCONFIGURATOR) are
required.

6.12 masterCONFIGURATOR

From version 2.8:
For programming functions (CLO, I-SELECT 2, power-up fading,
corridorFUNCTION, proportionSWITCH) and device settings (fade time,
ePowerOnLevel, DC level, etc.). For further information see
masterCONFIGURATOR manual.

6.13 deviceCONFIGURATOR

PC (windows) based software application to transfer parameters into our
drivers.
Workflow optimised for the use in OEM production line.
For further information see deviceCONFIGURATOR manual.

7. Miscellaneous

7.1 Insulation and electric strength testing of luminaires

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 insulation test with 500 V
1 second. This test voltage should be connected between the interconnected
phase and neutral terminals and the earth terminal.
The insulation resistance must be at least 2 MΩ.

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

Humidity: 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.

The LED Driver is declared as inbuilt LED controlgear, meaning it is intended
to be used within a luminaire enclosure.
If the product is used outside a luminaire, the installation must provide
suitable protection for people and environment (e.g. in illuminated ceilings).

7.3 Maximum number of switching cycles

All LED Driver are tested with 50,000 switching cycles.
The actually achieved number of switching cycles is significantly higher.
