Emergency lighting units
EM converterLED
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.
Commissioning
After installation of the luminaire and initial connection of the mains supply
and battery supply to the EM converterLED PRO the unit will commence
charging the batteries for 20 hours (initial charge). Afterwards the module
will conduct a commissioning test for the full duration. The 20 hours rechar-
ge occurs also if a new battery is connected or the module exits the rest
mode condition. The following automatic commissioning duration test is only
performed when a battery is replaced and fully charged (after 20 hrs) and
the interval time is not set to zero, otherwise the system is expected to per-
form the testing.
Functional test
The time of day and frequency of the 5 seconds function test can be set by
the DALI controller. The default setting is a 5 seconds test on a weekly basis.
Duration test
The time of day and frequency of the duration test can be set by the DALI
controller. The default setting is a duration test conducted every 52 weeks.
For 2 h operation:
The first commissioning duration test has a time of 120 minutes, subse-
quent through life tests are conducted for 90 minutes. When the battery is
changed or disconnected and re-connected the unit will next conduct a 120
minute test.
Prolong time
Prolong time can be set by the DALI controller. This is the delay time bet-
ween return of the mains supply and the end of the emergency operation.
The default prolong time is set as 0 minutes as specified within the DALI
standard.
Indicator LED will stay off for the duration of the prolong time.
Rest Mode / Inhibit Mode
Emergency operation is automatically started when the mains supply is
switched off. If the Rest Mode is activated, the discharging of the battery will
be minimized by switching off the LED output. If the Inhibit Mode has been
activated before the mains supply is switched off, Rest Mode will be automa-
tically switched on if the mains supply is switched off within 15 minutes.
Rest Mode and Inhibit Mode can be initiated by the DALI controller. The
REST command has to be sent after the mains supply has been discon-
nected and whilst the EM converterLED PRO is in emergency operation.
The INHIBIT command has to be sent while the EM converterLED PRO is
supplied by mains.
After a mains reset the EM converterLED PRO exits the Rest Mode. Rest
Mode and Inhibit Mode can both be disabled by sending the RE-LIGHT/
RESET INHIBIT command.
Test switch
An optional test switch can be wired to each EM converterLED.
This can be used to to:
• Initiate a 5 seconds function test:
press 200 ms < T < 1 s
• Execute function test as long as switch pressed: press > 1 s
• Reset selftest timer (adjust local timing):
press > 10 s
Timer reset functionality
The timer for function and duration test can be set to a particular time of the
day by either pressing the test switch for longer than 10 seconds or cycling
the unswitched line supply 5 times within 1 minute. The timer adjustment
will enable the test start time to be defined manually at time in day when
the timer was reset. It will also disable the adaptive test algorithm thereby
forcing the unit to perform the test at the same time rather than it being
defined by the adaptive algorithm. This function will only work provided the
interval time is greater than zero (automatic test mode enabled). The delay
timer value set when the unit was commissioned will be reloaded in order to
randomise the tests between adjacent units.
BlackBox data recording
Parameters providing information about the application and use are stored
in the EM converterLED PRO. The parameters stored provide information on
the mains, battery, LED output and emergency operation.
The BlackBox can be read out with the masterCONFIGURATOR and
deviceANALYSER.
DALI Controller
DALI controllers and hardware/software solutions are available from Trido-
nic. Please refer to the Lighting controls section.
