7.4 Testing
DALI Control
A DALI command from a suitable control unit can be used to initiate func-
tion and duration tests at individually selected times. Status flags are set for
report back and data logging of results.
When a DALI bus has not been connected or when a DALI bus is connected
but the DALI default DELAY and INTERVAL times have not been re-set
by sending appropriate DALI commands, then the EM converterLED PRO
will conduct self-tests in accordance with the default times set within the
EEPROM.
These default times are factory pre-set, in accordance with the DALI stan-
dard EN 62386-202, to conduct an automatic function test every 7 days and
a duration test every 52 weeks. Since the DELAY time is factory pre-set to
Zero, all units are tested at the same time. Test times can be changed with a
command over the DALI bus.
5.4 LED Driver compatibility
The EM converterLED emergency unit use 3 pole technology and is compa-
tible with most LED Drivers on the market, however it is important to check
that the rating of the LED Driver does not exceed the values specified below:
• The max. allowed output current rating of the associated LED Driver is
2.4 A peak (current rating of switching relays of EM converterLED)
• The max. allowed inrush current rating of the associated LED Driver is
60 A peak for 1 ms or 84 A for 255 μs (inrush current rating of switching
relay of EM converterLED)
• The max. allowed output voltage (U-OUT) of the associated LED Driver
applied to the EM converterLED output is 450V (voltage withstand
between adjacent contact of the single switching relay of the
EM converterLED)
• The max. allowed LED load of the associated LED Driver is 150 W in
operation. The load must be an LED module.
Check compatibility with the carried out function test (duration at least 5
seconds) individually for each device.
7.3 Status indication
System status is indicated by a bi-colour LED and by a DALI status flag.

7. Functions
7.2 Duration link selection
Emergency lighting LED Driver supplied with duration link in 3 hours positi-
on (position A).
The position of the link will only be read on first power up. If it is changed
afterwards both the battery and mains supply must be disconnected for 10
seconds to enable the EM converterLED to read the new link position on
reconnection of the battery and mains. It will lead to a false battery failure
indication if the link is changed after installation without this reset.

6.2 Nearfield communication (NFC)
The NFC Interface allows wireless communication with the LED Driver in
unpowered state. This interface offers the option to write configuration and
to read configuration, errors and events via a suitable NFC antenna and the
companionSUITE software.
Place the NFC antenna directly on the LED Driver to guarantee a correct
communication between the LED Driver and the NFC antenna. Any material
placed between the LED Driver and the NFC antenna can cause a deteriora-
tion of the communication quality. We recommend the use of following NFC
antennas:
www.tridonic.com/nfc-readers.
NFC is complied with ISO/IEC 15963 standard.
After programming the device via NFC power up the device one time for one
second till the deviceANALYSER can read out the parameters.
7.1 Integrated DALI bus power supply voltage (IPS)
This feature can optionally be activated (by default it is disabled).
IPS = 50 mA and IPS_max = 250 mA.
The minimum guaranteed output current is 50 mA.
Imax = 250 mA
Note: The voltage drop in the DALI wires must not exceed 2 V.
No other DALI power supply is allowed to be connected in parallel.
If the IPS function is activated, do not integrate the Driver into an
existing DALI network with active DALI bus power supply.
6. Interfaces / communication
6.1 Control input (DA+, DA–)
The DALI Interface allows communication with the Driver via a suitable DALI
control unit. The DALI interface is not SELV. Install the control cable (DALI
bus) in accordance to the requirements of low voltage installations.
DALI terminals are mains voltage proof.
