Overview
The Dialight Medium Intensity White Strobe and Red Beacon is designed for the
lighting of radio towers, wind generators and other obstructions to aerial
navigation.
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. With output magnitudes of less than
200VDC, working voltages are much lower than with xenon flashtube designs;
therefore, this system represents an advance in safety.
The light operates from a 100/230VAC 50/60 Hz supply. It consists of a White
Strobe section and a Red Beacon section controlled and monitored by a
microcontroller circuit. The red beacon type is determined by the top level part
number selection, either 2,000cd red or 170cd red to meet the Specific
requirements of the German “Wred” specification.
The system consists of a light engine and a power supply box joined by a multi-
way cable. The White Strobe section of the light engine consists of three layers
of white LEDs each driven from its own driver module contained in the power
supply enclosure. The Beacon section consists of 36 high-performance LEDs
driven by another module in the power supply enclosure. In addition, a control
box that may be located a considerable distance away from the light engine and
power supply, such as at the base of the tower, allows the system to be
controlled and monitored.
Options
See section on Switch Settings for additional information
Dimming
The light output can be dimmed to 30% and 10% of full output by means of two
control inputs (DIM0 and DIM1). For 30% dimming connect DIM0 to the Live
input terminal. For 10% dimming connect both DIM0 and DIM1 to the live
terminal. Note that the dimming feature affects both the Red Beacon and White
Strobe.

Night Mode
A number of options may be selected to determine how the light behaves when
in night mode. Either the Red Beacon or White Strobe can be chosen to come on
at night by means of the switches on the microcontroller board. When White at
night is chosen, it operates at 2000cd. The brightness when in White night mode
is not affected by the dimming inputs.
Red Beacon Flash Rate and Synchronization
The Red Beacon may either be flashed or steady burned. For steady burning
hold the Sync input terminal to the live terminal. For flashing either do nothing
with the Sync input (in which case the Beacon will flash at a default 20FPM) or
pulse the Sync input with 100-230Vac at the desired flash rate. The flashing will
synchronize to this pulsing. The flashing duty cycle is 50/50.
WRED Flashing Mode
The Wred flashing rate is; 1s light, 0.5s dark, 1s light and 1.5s dark. This may be
selected by means of a DIP-switch on the microcontroller board
White Strobe Flash Rate and Synchronization
Either do nothing with the Sync. input (in which case the White Strobe will flash
at a default 20FPM) or pulse the Sync input with 100-230Vac at the desired flash
rate. The flashing will synchronize to this pulsing.
Fault Signals
A fault is indicated if the microcontroller has detected a fault for 20 consecutive
flashes.
Two uncommitted solid-state relays provide indication of faults. One allows the
Red Beacon to be monitored and the other the White Strobe. The behavior of the
relays can be programmed using the DIP switch on the microcontroller board.
The relays can either be closed when a fault is detected, open on a fault or
pulsing when all is well. The latter mode is a fail-safe mode of operation.
If the fault clears, the fault signal will remain until power to the unit is cycled.

Notes:
1: After initial power up there may be a few seconds of delay before flashing
begins.
2: The default red Beacon and White Strobe flash rate is 20 flashes per minute.
3: The sync signal is not required if there is no need to synchronize with another
strobe. In the absence of a sync signal, the Strobe and Red Beacon will default
to 20 FPM.
4: For maximum immunity from the effects of radiated interference, the cable
from the Control Box to Power Supply Cabinet should be shielded with the
screen grounded at both ends.

Switch Settings
The microcontroller board has a switch block allowing a number of options to be
set up as follows:
1 2 3 4
ON
ON OFF
1 White at night Red at night
2 WRED pattern for red 50% duty cycle for red

consecutive faulty flashes.
2: When the fault relays are in pulse mode and their respective light is OK, they
pulse at 0.5 seconds off and 0.5 seconds on.

Mounting the Light Engine
Dialight recommends the installation of one or more lightning rods near the
installed Light Engine. The lightning rods should extend a minimum of three feet
above the height of the Beacon.
The Light Engine is mounted to the tower pedestal utilizing customer supplied ½”
hardware. Six mounting holes are provided on the Light Engine base (Figure 2).
These mounting holes will align with most tower pedestals. The Light Engine
must be installed level to maintain correct light output.

Operation and Initial Test
Warning: The power supply must be earthed
Prior to installation, it is recommended that the unit be tested to ensure no
damage was incurred during shipping.
1: Connect the multi-way cable between the light engine and power supply. Do
not force the connectors into their mating halves. Carefully align the mating
halves of the polarized connectors before tightening the locking ring.
2: Connect the power supply either to the Controller or to a mains supply in
accordance with the wiring table in section 2, using the connection terminals
located towards the bottom of the power supply cabinet.
Figure 4: Power/Signal Terminal Arrangement
Lightning Protection
The light incorporates protection against voltage surges that may be induced by
into the mains supply by nearby lightning strikes by means of MOVs and Gas
Discharge Tubes (GDTs). It is designed to withstand 6kV/3kA, 1.2/50us, 8/20us
Combination Wave Transients as described in IEC61000-4-5.

Maintenance and Troubleshooting
No regular scheduled maintenance is required for the light.
Warning:
Remove power from all wiring and circuitry before installing or working on the
light.
Each driver module has a red indicator light to indicate more than 50VDC present
on its output. In addition, the capacitor board has red indicator lights (one for
each of the large energy storage capacitors) to show the capacitor is charged to
at least 50V.
For safety, when the Power supply cabinet door is opened, an interlock switch
disconnects power from all the driver modules. If the unit has just been running, a
number of driver module indicators lights will be lit. These should go out within
about 30 seconds to indicate voltages on capacitors have been discharged to
less than 50V.
