T3X-1 System STAND ALONE ANALOGTunnel Lighting Control SystemT3X-1 system is a stand-alone based analog control panel. SCOPE APPLICATIONStructureShort tunnelUnidirectionalBidirectionalUnidirectional rampBidirectional underpassInside the T3X-1 System in a NEMA rated enclosure: (Pre-wired and tested to UL508A (CAN/CSA C22.2.0014-M91)Major ComponentsNote: Incoming power of 120 VAC. Other source of power can be converted down by the use of transformer inside the T3X-1 system.Normally closed contactsDip switchTrim potsPanel meterSelector switchesPower distributionMain controller:LC3XThree output channels for night and two daytime light levels.Hold-On timer, (0-160 min)Output channelAdjustable ascending input time delay (0-7 min)Adjustable descending input time delay (0-7 min) Optional programming sequenceAlternation of lights.Night/Day crossoverInput into the LC3X controllerPD sensor24VDC Input PowerReceives 0-10 voltage signal.On setpoint for all levels.10% fixed deadband.PD-SimSensor simulator tool for easy dial setup and recording of setpoints.Type of Tunnel light sourcesFluorescent (FL)Low Pressure Sodium (LPS)High Pressure Sodium (HPS)Metal Halide (MH)Light emitting diode (LED)
