2 DATA EXCHANGE The default setting of the digital dimming interface is set to DEXAL that delivers power to sensors and the following data: o Input Power Consumption: 2% accuracy above 10W threshold. o Operating Time: Updated rate 1 min o Max. Case Temperature: ± 5 C accuracy o Current Case Temperature: ± 5 C accuracy When using DALI 1.0 systems, choose the DALI option in the programming software. This will turn off the power delivery on the DEXAL interface. The interface is non-polarized in this mode. WIRING DIAGRAM Note 1: Maximum suggested remote mounting distance is 16 feet.

9 % Of Output Current LED THERMAL PROTECTION (NTC) CHARACTERISTIC The LED thermal protection feature of the OTi 50W helps reduce the temperature of the LED module by reducing the output current in case of abnormal temperature conditions. To use this feature, a third party NTC thermistor should be connected to the LED power supply as shown in the wiring diagram below. In the end application, care must be taken to place the NTC thermistor close to the hottest spot on the LED module. If LED thermal protection is not required the NTC port on the LED power supply connector can be left open. Vishay, EPCOS, Murata, Panasonic are some of the manufacturers of NTC thermistor. EPCOS part number for reference only B57164K153J 25 C). Murata part number for reference only - NCP03XH223J05RL 25 C) Note 3: Graphs for reference. The derating limits can be programmed using the OT Programmer 100 Derating start = 6.3kΩ; Derating end = 4.3kΩ; Min output level = 10% R NTC in kω CONSTANT LUMEN MAINTENANCE The Constant Lumen Maintenance feature of the OTi 50W helps to maintain the required lumen output of the fixture at a constant level throughout its lifetime. In general LED s lumen output will depreciate over time and in order to maintain sufficient light level towards the end of lifetime, the LED s are driven at high current initially and will result in more energy consumption. The constant lumen maintenance will give the flexibility to drive the LEDs at optimal driving current throughout its lifetime. This helps in energy savings, constant light output and enhanced reliability of the system. END-OF-LIFE INDICATOR The End-of-Life indicator helps the end user to receive a signal from the fixture indicating that it has reached its programmed life-time. After the LED driver reaches the programmed life-time, whenever it is turned ON, it stays at Dim level (10%) for 10 minutes and reaches its appropriate level. ECS301 6/2017 9
