Section 1: Overview

The Dialight OEM Dual Red Beacon White Strobe Driver and Flash Head is
designed to be incorporated into Medium Intensity L865 systems for the lighting
of radio towers, wind generators and other obstructions to aerial navigation, as
specified by the FAA and FCC.

This design uses LED technology for light output both from the Beacon and
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.

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.

Note:
1: If conductor thickness is reduced the maximum permissible distance between

Flash Head and power supply will be reduced.
2: For maximum immunity to the effects of radiated interference and lightning, the

cable from the Control Box to Power Supply Cabinet must be shielded with the
shield bonded to ground at both ends.

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.

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

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.

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

Section 10: Mounting the Flash Head

Dialight recommends the installation of one or more lightning rods near the
installed Flash Head. 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

No regular scheduled maintenance is required for the Driver module or Flash
Head.

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.

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 18: Serial Port Specification

Overview

The serial port on the microcontroller is accessible through the J7 connector
located on the microcontroller board. 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.
