This design uses LED technology for light output from the White Strobe. Unlike conventional xenon flashtube technology, little or no maintenance is required during its lifetime. Working voltages of less than 200VDC are much lower than those of xenon flashtube designs; therefore, this system represents an advance in safety. Only the Flash Head is Certified to Class I, Division 2 rating. The Power supply and subcomponents are NOT Class I, Division 2 certified. The power supply must be installed in a safe, non-classified location. A high level of functionality and versatility is provided by the Driver module. Not only does it generate the required LED drive currents, but also provides: Timing and synchronization Fault monitoring Dimming features Options for night operation Serial port configuration Data logging The Driver module consists of a plate on which are fixed (See Diagram): (W1 and W2) Two White Strobe Drivers (R) One Red Beacon Driver (M/F) One Microcontroller / Filter / Protection and Interface module (CAP) One Capacitor module (TB) One Terminal Block The system operates from a nominal 48Vdc/100W supply. Switches on the microcontroller board allow various options as to how the system operates to be selected. _____________________________________________________________________________ Dialight Corporation 1501 Route 34 South Farmingdale NJ 07727 Tel: 732.919.3119 Fax: 732.751.5778 Web: www.dialight.com Page 3 of 25 Document No. 9100-127-1383-99 Rev B Release Date: 10/7/2010 _____________________________________________________________________ POWER SUPPLY / HEAT SINK ASSEMBLY DC in EMI Filter, Transient & Reverse Polarity Protection I/O Signal Opto-Isolators White Strobe Driver 1 Microcontroller circuit White Strobe Driver 2 To Light Engine Red Beacon Driver Control Signals DRIVER BLOCK DIAGRAM _____________________________________________________________________________ Dialight Corporation 1501 Route 34 South Farmingdale NJ 07727 Tel: 732.919.3119 Fax: 732.751.5778 Web: www.dialight.com Page 4 of 25 Document No. 9100-127-1383-99 Rev B Release Date: 10/7/2010 _____________________________________________________________________ Section 2: Installation and Wiring The Driver module should be mounted inside a grounded, metal enclosure to provide environmental, electromagnetic interference and safety protection. For safety, an interlock switch should be fitted to the Controller cabinet door such that when opened, power is disconnected from the system. A multi-conductor cable needs to be provided to connect the Driver to the Flash Head.

FLASH HEAD TERMINAL BLOCK CONNECTION The cable connects to the Driver by means of the terminal blocks on the DIN Rail. The conductors connect one to one, to the corresponding terminals in the Flash Head. Warning: Take care to connect correctly, as incorrect operation can cause damage to the driver modules. _____________________________________________________________________________ Dialight Corporation 1501 Route 34 South Farmingdale NJ 07727 Tel: 732.919.3119 Fax: 732.751.5778 Web: www.dialight.com Page 7 of 25 Document No. 9100-127-1383-99 Rev B Release Date: 10/7/2010 _____________________________________________________________________ Section 4: System Installation Recommendations for EMC and Lightning Immunity 1: Electrically bond the shield of the Flash Head cable to ground at both ends. Make 360-degree ground connections around the braid or foil (avoid pigtails). 2: If there is a drain-wire in the cable, connect to ground at both ends 3: Ensure the Flash Head is electrically bonded to the tower 4: Minimize loop areas by tying all cables against the tower or passing through conduit 5: Ensure the power-supply cabinet is electrically bonded to the tower 6: Ground any spare/unused conductors in the Flash Head cable at both ends 7: Keep wiring tidy with cables performing different functions tied up separately. Keep power, control and output cables separate. Tie up wires to minimize loop areas. For a detailed step by step procedure, refer to “Recommendations for Proper Grounding to Minimize Lightning Damage” guide available at http://www.dialight.com/assets/installation_manuals/9100127140699.pdf _____________________________________________________________________________ Dialight Corporation 1501 Route 34 South Farmingdale NJ 07727 Tel: 732.919.3119 Fax: 732.751.5778 Web: www.dialight.com Page 8 of 25 Document No. 9100-127-1383-99 Rev B Release Date: 10/7/2010 _____________________________________________________________________ Section 5: Ferrites Ferrites act to increase the inductance of a conductor and can be effective at reducing or eliminating RF or lightning immunity problems. Some Ferrites are already included in this model, both inside the Flash Head and in the Power Supply as part of lightning protection and RF immunity on the Flash Head cabling. However, since every installation is different and extreme or unusual conditions may be encountered, it may occasionally be prudent or necessary to add more to control or power lines. Different Ferrite materials have different effectiveness depending on the frequency to be attenuated. They should be chosen for maximum attenuation at the frequency of concern. As a general rule, the more material in the ferrite the higher will be the attenuation. For maximum lightning immunity and EMC performance, choose ferrite materials with good broad band attenuation, such as Steward 28B1020-100. Better attenuation will be obtained if the cable can be put through the center more than once. Inductance is proportional to the square of number of turns so twice through is theoretically 4 times the inductance of 1 turn. Multiple ferrites (including different types in combination) can be used on a single cable. Section 6: Flash Rate & Steady Burn Both Red Beacon and White Strobe default to 40 flashes per minute. The flash rate may be adjusted between 20-40 fpm by means of the Sync input. _____________________________________________________________________________ Dialight Corporation 1501 Route 34 South Farmingdale NJ 07727 Tel: 732.919.3119 Fax: 732.751.5778 Web: www.dialight.com Page 9 of 25 Document No. 9100-127-1383-99 Rev B Release Date: 10/7/2010 _____________________________________________________________________ MICROCONTROLLER BOARD (POWER SUPPLY) Section 7: Control Inputs Each input is active when the input terminal is connected to the negative of the supply input (Common). Input/Output Sync Input Synchronizes both White Strobe and Red Beacon. When held steady (connected to Common) the Red Beacon burns constant, and the White Strobe flashes at 40FPM. To synchronize the white and preset red flash rate, a 1 PPM signal may be provided. Alternately, a synchronization pulse may be applied at every flash to alter the flash rate. In both modes, the synchronization signal must be asserted for at least 0.1s to ensure that it is properly detected. Sync Output Independent synchronization signal which may be connected to the Sync input of other supplies when multiple synchronized lights are required (leave all other Sync Outputs unconnected) In Day mode Sync output defaults to 40FPM In Night mode Sync output defaults to 30FPM _____________________________________________________________________________ Dialight Corporation 1501 Route 34 South Farmingdale NJ 07727 Tel: 732.919.3119 Fax: 732.751.5778 Web: www.dialight.com Page 10 of 25 Document No. 9100-127-1383-99 Rev B Release Date: 10/7/2010 _____________________________________________________________________ Master Strobe Sync Out Sync In Slave Strobe Sync In To Sync In of other synchronized strobes DIAGRAM SHOWING HOW TO SYNCHRONIZE FLASH RATES Day/Night contact Connect to Common for Night mode Dim 0 Connect Dim 0 to Common to reduce light output to 30% of maximum Connect Dim 1 to Common to reduce light output to 10% of maximum Note: Dimming affects both White Strobe and Red Beacon Dim 1 Two uncommitted solid-state relay outputs are provided to indicate a fault with the Red or White Beacon; Red Fault A Red Fault B White Fault A White Fault B Each solid state relay is rated for up to 600V/40mA max, 20mA continuous.

The lightning rods should extend a minimum of three feet above the height of the Flash Head. The Flash Head is mounted to the tower pedestal utilizing customer supplied ½” hardware. Six mounting holes are provided on the Flash Head base (Figure 2). These mounting holes will align with most tower pedestals. The Flash Head must be installed level according to the bulls-eye level on the light engine to maintain light output in accordance with FAA requirements. BASE – BOTTOM VIEW Section 11: Maintenance The only regular scheduled maintenance that is required for the system is to check the Lens/ dome of Flash Head is not damaged or cracked. Replace the Flash Head if this is the case. _____________________________________________________________________________ Dialight Corporation 1501 Route 34 South Farmingdale NJ 07727 Tel: 732.919.3119 Fax: 732.751.5778 Web: www.dialight.com Page 13 of 25 Document No. 9100-127-1383-99 Rev B Release Date: 10/7/2010 _____________________________________________________________________ U Section 12: Capacitor Voltage Indication Safety Warning This unit holds a number of large capacitors for storage of the energy required during the Strobe’s flash duration. These capacitors may be charged with voltages up to 185Vdc. Associated with each capacitor is a red indicator LED. When lit, this indicates the capacitor voltage is 50V or higher. When power is removed from the module the capacitors automatically discharge to 50V within 30 seconds. Do not attempt any maintenance or wiring until the capacitors have been allowed time to discharge to a safe level and all the red indicator LEDs have gone out. Section 13: Strobe Driver Diagnostic LEDs The two Strobe Driver modules each have three indicator LEDs. LED 2 and 3: Each is driven from one of the driver’s three outputs. Therefore normally each one should blink at the same rate as the Strobe output. These indicate the driver module is operating. If for some reason some of the White LEDs in the Flash Head do not operate yet these diagnostic LEDs do blink, this would indicate the fault is not with the Driver module. Should one or more of these LEDs be stuck on or not flash at all, this may indicate a fault with the driver module. LED 4: Lights continuously when the Strobe is energized to show that an excess of 50V is present at its output. If this does not light it might indicate either the Driver module is faulty or not receiving any power. Section 14: Red Beacon Driver Diagnostic LED LED 1 on the Red Beacon Driver indicates more than 50V is present on the output and gives a good indication that the Beacon Driver module is working. _____________________________________________________________________________ Dialight Corporation 1501 Route 34 South Farmingdale NJ 07727 Tel: 732.919.3119 Fax: 732.751.5778 Web: www.dialight.com Page 14 of 25 Document No. 9100-127-1383-99 Rev B Release Date: 10/7/2010 _____________________________________________________________________ Section 15: Microcontroller Board Diagnostic LEDs LED 1 (Red) on the microcontroller board shows the status of the Flash Head. In white mode, it will flash the driver number of any white drivers that currently have faulty strings. In red mode, it will flash once every two seconds if the red current is low and twice if the current is too high. It will not flash at all when all drivers are operating properly. LED 2 (Green) on the microcontroller board pulses once every time a flash is initiated in the Flash Head. Section 16: Troubleshooting Refer to the Trouble Shooting Guide.

It can be used to configure the strobe unit, monitor it for status information, or provide override capability for the external control signals. The port itself, as well as the protocol for accessing it, is described below. Connection This port sends and receives raw serial data; it should be noted that there is no level shift performed on the signals from the microcontroller. If the port is to be used to connect to a computer or other device with a full RS232 port, a level shifter will be required. Also, it is good practice to electrically isolate the microcontroller connection from the computer to protect both the strobe unit and computer from dangerous voltages. The serial port connection is through connector J7 on the microcontroller board, with pin 1 marked by a white arrow. The pinout of this port is listed below. Pin 1: Ground Pin 2: +5V (this pin may be used to power an external level shifter, up to 100mA) Pin 3: RX pin (receive to the microcontroller) Pin 4: TX pin (transmit from the microcontroller) Pin 5: No connect The port has the following characteristics: 19200 baud 8 data bits One stop bit No parity bit No flow control While a connection to the port can be made through HyperTerminal or a similar simple serial communication package, it should be noted that the data received from the port is encoded in binary rather than ASCII, and therefore will be unreadable by such software. Protocol There are three sets of data that can be transmitted across the serial connection: Configuration, Status and Override. All “Master” transactions are TO the microcontroller board, and all “Slave” transactions are FROM the microcontroller board. _____________________________________________________________________________ Dialight Corporation 1501 Route 34 South Farmingdale NJ 07727 Tel: 732.919.3119 Fax: 732.751.5778 Web: www.dialight.com Page 17 of 25 Document No. 9100-127-1383-99 Rev B Release Date: 10/7/2010 _____________________________________________________________________ Configuration Configuration information can be read or written to the microcontroller board using the following protocol.
