6.3 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.
The DELAY and INTERVAL time values must be re-set when the emergency
system test times are to be scheduled by a DALI control and monitoring
system.
Note that once the default values have been set to Zero, tests will only be
conducted following a command from the control system. If the DALI bus is
disconnected the EM converterLED PRO does not revert to self-testing
mode.
Note: If the battery is connected the DALI communication is only possible
after power reset.
Addressing
The EM converterLED PRO includes the EZ easy addressing system which
allows addressing and identification by using the bi-colour LED. Binary
address codes given by the LED can be simply converted to the DALI
addresses 0 to 63. For single handed addressing using this method it is
necessary to send a broadcast ident command every 3 to 9 seconds. During
this command the LEDs will be switched off and the indication LED will flash
the 6 bit binary address preceded by a 3 second start indication period.
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 of the associated LED Driver applied to
the EM converterLED output is 450V (voltage withstand between adja-
cent 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.
6. Functions
6.1 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.
