  • Page 5: Introduction

    APPLICATION The D-1LVS L-865 Controller is for use on lighting structures or towers that are approved to be lighted with Medium Intensity Strobes in accordance with the FAA’s Advisory Circular 70/7460-1K.

  • Page 6: Installation

    D-1LVS CONTROLLER INSTALLATION POWER SUPPLY CONTROL CABINET MOUNTING The power supply control cabinet can be located at the base of the structure or in an equipment building. Mounting Dimensions can be found in Section 1.2, on page 1. Pay particular attention when choosing your controller mounting location to ensure proper door opening and room for service personnel.

  • Page 7: Power Wiring

    D-1LVS CONTROLLER 2.3.4 Install the photocell into the receptacle and twist to the right while depressing to lock into place. POWER WIRING (Refer to Drawing H40-283) Power wiring to the control cabinet should be in accordance with local methods and the National Electric Code (NEC).

  • Page 8: Lighting Kit Wiring

    D-1LVS CONTROLLER 2.5.2 Lighting Kit Wiring Install wiring between the controller and the beacon utilizing strobe cable (TWR LIGHTING CANNOT WARRANTY SYSTEMS THAT method. EMPLOY SPLICING CABLE.) Refer to drawings HDO-283 and 500-12 for install of lighting kits. Follow these minimum guidelines as well as any local or end user addition requirements.

  • Page 9: Power Failure (Pf)

    D-1LVS CONTROLLER 2.6.3 Power Failure (PF) While the controller is in normal operation, shut off power to the controller at the breaker panel. Alarm should be prompt. Reset breaker to resume normal operation. 2.6.4 Photocell (PC) Controller should be in the daymode of operation when performing this test.

  • Page 10: Theory Of Operation

    D-1LVS CONTROLLER THEORY OF OPERATION THE POWER SUPPLY The AC line is sent to transformer T1 through fuse F1 and relay K1. In order for K1 to energize and complete the circuit to T1, the safety interlock switch CSS, BSS, must be closed.

  • Page 11: Timing Circuit

    D-1LVS CONTROLLER The flashtube contains a gas called Xenon. When the high voltage energy in the storage capacitors is connected to the flashtube, nothing will happen since Xenon in its natural state is not a conductor of electricity. However, when a very short duration...

  • Page 12: Photocell (Pc)

    D-1LVS CONTROLLER The power failure alarm relay is energized during normal operation. Should the power be removed for any reason, then relay K6 would drop, creating an alarm for the customer alarm transmitting device. 3.5.2 Photocell (PC) The photocell alarm relay is energized whenever the photocell or SW3 is on.

  • Page 13: High Voltage

    D-1LVS CONTROLLER 3.7.2 High Voltage The Cathode side of the high voltage HV is routed through current limiting resistor. When the unit is in daymode, D14 will be at full brightness when the capacitors are at full charge, but dims with the discharging of the storage capacitors.

  • Page 14: Flash Verified

    D-1LVS CONTROLLER 3.7.7 Flash Verified Current from the Cathode side of the flashtube (FTC) is sent through the current sensing transformer T1 on PCB #1. T1 will send a pulse to the gate of the SCR’s Q2 and turns it on. Capacitor C11 via Q2 will send voltage to LED5 (D8).

  • Page 15: Troubleshooting

    D-1LVS CONTROLLER TROUBLESHOOTING Much of the troubleshooting of this system will consist of correcting a “beacon out” situation. There may also be a failure mode where the flashtube is still flashing, but at the wrong rate or the wrong intensity.
