If it is changed afterwardsboth the battery and mains supply must be disconnected for 10 secondsto enable the EM powerLED EZ-3 to read the new link position on reconnectionof the battery and mains. It will lead to a false battery failure indication if the linkis changed after installation without this reset.Further technical dataThe EM powerLED has a unique power regulation circuit; this is designed to limitthe total power drawn from the battery in the event of using LED’s with a forwardvoltage (Vf) higher than 3.4 V.In such cases the unit will reduce the LED current in order to maintain anacceptable drain current from the battery and hence meet the required durationtime. This feature enables the EM powerLED PRO EZ-3 to have minimum batterycount for a given range of LED’s.Storage• Batteries should be stored within the specified temperature range inlow humidity conditions. Optimal storage conditions are– temperature: +5 °C to +25 °C– humidity: 65 % ±20 %• Avoid atmosphere with corrosive gas• It is recommended to disconnect the battery before store or delivery• Avoid to store the batteries discharged• A long term storage in open circuit leads to battery self discharge anddeactivation of chemical components. It could be required to charge and dischargethe batteries a few times to recover the initial performance.BatteriesConnection method: 4.8 x 0.5 mm spade tag welded to end of cellFor stick packs this connection is accessible after the battery caps have beenfitted.To inhibit inverter operation disconnect the batteries by removing the connectorfrom the battery spade tag.For battery data see separate data sheet.Data sheet 03/15-EM001-11Subject to change without notice.www.tridonic.com 6
Emergency lighting unitsEM powerLEDTesting:DALI ControlA DALI command from a suitable control unit can be used to initiate function andduration tests at individually selected times. Status flags are set for report backand data logging of results.When a DALI bus has not been connected or when a DALI bus is connected butthe DALI default DELAY and INTERVAL times have not been re-set by sendingappropriate DALI commands, then the EM powerLED PRO EZ-3 will conductself-tests in accordance with the default times set within the EEPROM . Thesedefault times are factory pre-set, in accordance with the DALI standard EN62386-202, to conduct an automatic function test every 7 days and a durationtest every 52 weeks. Since the DELAY time is factory pre-set to Zero, all unitsare tested at the same time. Test times can be changed with a command overthe DALI bus.The DELAY and INTERVAL time values must be re-set when the emergency systemtest 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 conductedfollowing a command from the control system. If the DALI bus is disconnectedthe EM powerLED PRO EZ-3 does not revert to self-testing mode.AddressingThe EM powerLED PRO EZ-3 includes the new EZ easy addressing system whichallows addressing and identification by using the bi-colour LED in conjunctionwith the EM PRO addressing tool. Binary address codes given by the LED can besimply converted to the DALI addresses 0 to 63. For single handed addressingusing this method it is necessary to send a broadcast ident command every 3to 9 seconds. During this command the main fluorescent lamp will be switchedoff and the LED will flash the 6 bit binary address preceded by a 3 second startindication period.CommissioningAfter installation of the luminaire and initial connection of the mains supply andbattery supply to the EM powerLED PRO EZ-3 the unit will commence chargingthe batteries for 20 hours (initial charge). Afterwards the module will conduct acommissioning test for the full duration. The 20 hours recharge occurs also if anew battery is connected or the module exits the rest mode condition. The followingautomatic commissioning duration test is only performed when a batteryis replaced and fully charged (after 20 hrs) and the interval time is not set tozero, otherwise the system is expected to perform the testing.Functional testThe time of day and frequency of the 5 seconds function test can be set by theDALI controller. The default setting is a 5 seconds test on a weekly basis.Duration testThe time of day and frequency of the duration test can be set by the DALIcontroller. The default setting is a duration test conducted every 52 weeks.DALI ControllerDALI controllers and hardware/software solutions are available from Tridonic.Please refer to the Lighting controls section.Life-timeAverage life-time 50,000 hours under rated conditions with a failure rate of lessthan 10 %. Average failure rate of 0.2 % per 1000 operating hours.Isolation and electric strength testing of luminairesElectronic LED Drivers can be damaged by high voltage. This has to be consideredduring the routine testing of the luminaires in production.According to IEC 60598-1 Annex Q (informative only!) or ENEC 303-Annex A, eachluminaire should be submitted to an isolation test with 500 VDC for 1 second. Thistest voltage should be connected between the interconnected phase and neutralterminals and the earth terminal. The isolation resistance must be at least 2 MΩ.As an alternative, IEC 60598-1 Annex Q describes a test of the electrical strengthwith 1,500 VAC (or 1,414 x 1,500 VDC). To avoid damage to the electronic devicesthis test must not be conducted.Status indicationSystem status is indicated by a bi-colour LED and by a DALI status flag.LED indiction Status KommentarPermanent green System OK AC modeFast flashing green(0,1 sec on – 0,1 sec off)Slow flashing green(1 sec on – 1 sec off)Function testunderwayDuration testunderwayRed LED on Load failure Open circuit / Short circuit / LED failure 1Slow flashing red(1 sec on – 1 sec off)Fast flashing red(0,1 sec on – 0,1 sec off)Battery failure Battery failed the duration test or function /Battery is defect / Incorrect battery voltageCharging failure Incorrect charging currentDouble pulsing green Inhibit mode Switching into inhibit mode via controllerBinary transmission of addressvia green/red LEDAddressidentificationDuring address identification modeGreen and red off DC mode Battery operation (emergency mode)1 If the EM powerLED is operated in non-maintained mode and an LED fault is detected, the redindicator LED will be illuminated and the output will be stopped. The unswitched mains supplymust be switched off before the LED is changed in order that the new LED can be detected. Afunction or duration test will not reset the fault indication.Prolong timeProlong time can be set by the DALI controller. This is the delay time betweenreturn of the mains supply and the end of the emergency operation. The defaultprolong 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 ModeRest mode can be initiated by the DALI controller. The appropriate commandshould be sent after the mains supply has been disconnected and whilst themodule is in emergency operation. A mains reset is required to exit the restmode. EM powerLED PRO EZ-3 does support the re-light command via the DALIbus.Test switchAn optional test switch can be wired to each EM powerLED PRO EZ-3. This canbe used to initiate a 5 seconds function test by a short press < 1 second.Data sheet 03/15-EM001-11Subject to change without notice.www.tridonic.com 7
