3.1. About the device
The rapid growth of LED technology within the lighting sector has created a need for suitable emergency lighting systems for
luminaires. Thanks to power control in emergency operation, the slim, transparent range of the EM converterLED product group offers
utmost flexibility for a number of combinations of LED light sources with LED Drivers by Tridonic and other renowned manufacturers.
As an LED Driver for non-maintained mode, EM converterLED is used in combination with standard and dimmable LED Drivers. It is
available as SELV and Non-SELV versions and with different functions. According to SELV classification, versions with a maximum
output voltage of 52V, 97V and 200V are available.
Available are versions for manual testing (BASIC), for selftests (ST) and DALI addressable devices (PRO) for automatically controlled
and monitored testing.
This document covers the selftest version (ST) of the portfolio. The PRO version is covered in a separate documentation (see
).Reference list, p. 38
3.2. Testing of emergency systems
There are statutory requirements covering the testing of emergency systems in buildings accessible to the public. This includes that
testing must be carried out at a time of minimum risk, normally during unsocial hours, and must allow time for the batteries to be
recharged before the next expected occupancy of the building.
Without automated test systems all steps must be performed manually. This includes the initiation of the test by interrupting the
power supply, the visual inspection of each luminaire and the logging of all test results.
The emergency LED Driver EM converterLED ST enables automated selftesting with a number of advantages:
...
The EM converterLED ST covers the complete test procedure including error indication. This is possible without any
expensive, time-consuming testing procedures. Tests are therefore more reliable and cheaper.
_
The EM converterLED ST devices are designed to meet the requirements of IEC 62034 (Automatic test systems for battery
powered emergency escape lighting).

5.1. Adjustable output current
5.1.1. Description
If the EM converterLED ST switches to emergency operation in case of a power failure, the device will detect the forward voltage of
the connected LED modules and set the correct LED current. Setting a constant output power ensures maximum light output in
emergency mode for the specified operating time.
An EM converterLED ST with approx. 3, 4 or 5 watts output power operates the connected LED modules with the output power
mentioned before. For this purpose, the device detects the connected LED forward voltage, and adjusts the LED forward current to
the appropriate value, resulting in an output power of approx. 3, 4 or 5 watts.
...
INOTICE
At the lowest range of permissible forward voltage, the efficiency may be slightly lower. In this case the output power is also
slightly lower.

5.2. Intelligent multilevel charging system
The multilevel charging system is used for minimising charging times while maximising battery life. During normal functional mains
operation the module charges the batteries using a specially developed charging algorithm.
When the permanent power supply is switched on for the first time the EM converterLED ST starts to charge the batteries for 20
hours in fast charge mode. This 20-hour preparatory charge ensures that the new batteries are completely charged before being used.
The 20-hour recharge is also used if a new battery is connected or if the device leaves the Rest mode (see Rest mode, Inhibit mode
).and Relight command, p. 14
At the end of the 20-hour charge the module automatically switches to trickle charge mode. This ensures that the batteries remain at
optimum charge levels and avoids any overheating due to overcharging.
After a power outage and subsequent emergency mode the EM converterLED ST recharges the batteries in fast charge mode.
However, the charge time is set so that only the power consumed during emergency mode is replaced. If emergency mode did not last
as long as the prescribed operating time the charging time will be reduced. If emergency mode extended for the full operating time
the charging time will be 10 hours for modules with an operating time of 1 hour, and 15 hours for modules with an operating time of 2
and 3 hours. Once the batteries are fully charged again the module automatically switches to trickle charge mode.
In trickle charge mode the battery status is continually monitored to ensure that the charging currents and battery voltages remain
within the specified limits. The status LED also shows such faults locally.
If a duration test is required while the battery is not yet fully charged the test will be postponed until charging is complete. This
prevents a duration test from being carried out with a battery that is not fully charged.
If the power supply fails during rapid charging the module will power the lamp immediately in emergency mode for as long as the
charge in the batteries will allow.
Initial charge mode:
20 hours of high charging current at the start to prepare the new battery cells and fully charge them.
_
Trickle charge mode:
Continuous low charge to maintain battery output and reduce battery temperature.
_
Fast charge mode:
Automatic adjustment of the charge time ensures minimal overcharging:
_
10 or 15 hours of rapid charge after a full discharge._
Shorter charge time after only a partial discharge._
NiCd batteries are charged with a constant charging current in trickle charge mode_
Special NiMH devices charge with a pulsed charging current in trickle charge mode_
INOTICE
A partially charged battery is defined as one for which the charger is operating in fast charge mode.
A fully charged battery is defined as one for which the charger is operating in trickle charge mode.

5.3. Rest mode, Inhibit mode and Relight command
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.
Rest mode can be used during short periods of time when a building is completely unoccupied and the mains supply is to be switched
off intentionally, for example during a holiday period. Using Rest mode prevents a full discharge and possible damages to the
batteries during these times.
Rest mode has to be activated by a competent person. Activation is only possible after the mains supply has been switched off.
Contrary to this, if the Inhibit mode has been activated in advance, Rest mode will be automatically switched on if the mains supply is
switched off.
By sending the Relight command both modes, Rest mode and Inhibit mode, will be deactivated. The emergency unit will switch back
to the previous operating mode. If it has been in Rest mode, it will switch back to emergency mode, if it has been in Inhibit mode, it will
switch back to charging mode.
For all the different changes, activating Rest mode and Inhibit mode and sending the Relight command, DC voltage pulses of different
lengths are used. The table at gives an overview of all the operating modes.Switching between operating modes, p. 16
5.3.1. Activate Rest mode
Rest mode is activated as follows:
5.3.2. Deactivate Rest mode via Relight command
By sending the Relight command the Rest mode is deactivated. The emergency unit will switch back to emergency mode.
To deactivate Rest mode via Relight command, proceed as follows:
½CAUTION!
Even in Rest mode there is self discharge current and an extremely small level of discharge current flowing from the batteries. If the
batteries remain in Rest mode for prolonged periods of time this can lead to deep discharge and potential damage. Further
information can be found in the data sheet of the batteries (see ).Reference list, p. 38
Disconnect power supply_
Apply DC voltage pulse at the two terminal points "REST/L" and "REST/N"_
The signal ofmust have an amplitude 9.5 - 22.5 V with a pulse length of 150 - 1,000 ms_
The polarity of the voltage pulse does not matter_
INOTICE
Rest mode cannot be activated as long as the power supply hasn't been disconnected.
The maximum number of emergency units on one bus is 100 pieces with a maximum recommended cable length of 1,000 metres.
Rest mode voltage can be applied across all emergency modules (parallel connection).

5.3.7. Switching between operating modes
The device has four different operating modes (Standby/Charge mode, Emergency mode, Rest mode and Inhibit mode). Depending on
the initial mode and the length of the applied DC voltage pulse the device switches between these operating modes. The following
table gives an overview:

Inhibit mode is
activated
The Inhibit mode makes it possible to set the emergency mode to "inhibited"; in this
mode, the power can be turned off without switching to emergency mode.
The Inhibit mode is activated by sending the inhibit signal, while the modules are still
connected to mains. Just as in Rest mode, the device supports the Relight functions.
After a break of 15 minutes, the inhibit mode is automatically reset.

After an exchange of the LED module, the indicator LED remains permanent
RED. The lamp failure indication remains set until a function test has been
successfully completed (automatically with the weekly function test or
immediately by briefly interrupting the power supply or by manually starting
the function test with a test switch (see )).Starting the function test, p. 23
The LED module's mains operation does not reset the lamp failure indication.
INOTICE
While the battery is in trickle charge mode and the mains supply is connected,
the micro controller in the emergency unit monitors the charging parameters. If
an error is detected or a parameter is out of tolerance, the indicator LED
switches to fast flashing RED. If the error has been corrected, the indicator LED
immediately switches back to GREEN and continues the charging operation of
the battery.

6.1. Test times and test intervals
Devices of the EM converterLED ST series are tested via selftest function. The following table gives an overview of the parameters:
Test trigger Test times Test intervals
Test
triggered by
emergency
lighting unit
There are two variants for setting the test time. In some cases different rules apply for the
setting of the day and the time:
To prevent that the emergency lighting tests of all luminaires are carried out at the same time,
each luminaire has a pre-programmed code which delays the test time for a specified time (see
).Commissioning test, p. 20
Test time intervals
between the tests
are fixed:
6.2. Commissioning test
The commissioning test is a first duration test. The relevant standard (IEC 62034: Automatic test systems for battery powered
emergency escape lighting) requires that such a test is carried out after the installation.
The commissioning test is often made more difficult because the power supply is switched on and off during the installation phase.
This is the case, for example, if the site is powered off at night for security reasons. To address this problem, the EM converterLED ST
monitors the power supply and will only start with the commissioning test if the power supply hasn't been interrupted for 5 days.
To prevent that all the luminaires perform the emergency test at the same time, each luminaire has a pre-programmed code with a
value of 1-28, which delays the test time of that luminaire for a specified time.
28 days after the start of the commissioning all devices will have completed the required commissioning test.
The day of the commissioning test serves as a reference point for all further function and duration tests (see Test times and test
Automatic setting of the function test:
The time of the function test is the same as the time when the device was first
connected to the power supply (see (1) in above diagram), the day of the function test
is the same as the day when the commissioning test was carried out (see (5) in above
