E2 SYSTEM OVERVIEW
Note - this is a typical installation example. It is possible to feed the input voltage
in and out of the controller box to the additional power supply boxes, i.e. “daisy-
chaining” is acceptable.
Installation Tips and Requirements
Cable Requirements
The power supply only requires 3 wiring connections:
WARNING: Failure to use specified cable will VOID all warranties and could cause
premature failures.
1) Mains connection using a 3 conductor Power Cable (14AWG minimum to 10AWG
maximum).
2) An RS485 communications cable. This is required to be a 3 conductor cable
(18AWG minimum) with a shield or braid as well as a drain wire.
3) The connection between the Flash Head and the Power supply. This is required to
be 8 conductors of 18AWG minimum or 4 conductors of 14AWG minimum, with a
shield or braid as well as a drain. Maximum run distance is 550 feet.
4) Common Ratings for the above cables:
-40ºC to 90ºC temperature rating minimum (stationary use)
Outdoor rated/ wet location
UV resistant
Minimum of 300V rating (if 277Vac is used then a 600V cable is required)
UL, CSA and RoHS complaint

Power Supply Terminal Connection
Located at the bottom right hand side of the enclosure is the terminal block required for
connecting the Positive, Negative and Earth Ground to the power supply.
WARNING: Floating Neutrals are not permissible within the wiring of the system and the
installer must verify the connections. This will “Void” all warranties.
WARNING: Ground connection is required to provide safety and proper operation of the
system.
WARNING: There can be no more than 305Vac measured from Live to Earth ground on
TB1
NOTE: The load and voltage loss of the cable must be quantified before selecting the
cable size requirements.

TRANSLATOR & RS485 JUNCTION BOARD
NOTE: Rotary switch SW1 on the Translator must be set to a unique address for each
Power Supply connected to the Controller.
NOTE: If ordered as a system, typically SW1 will be factory set per this table (i.e. JB4-
xxxxxxxxxx would have SW1 set to Position 3). This should be confirmed by the
installer. Replacement plates will typically have SW1 set to 0; the switch must be set by
the installer to match the address that is being replaced.

RS485 shall be connected throughout the system per the simplified diagram below.
Both the Controller and Power Supply enclosures house the same RS485 junction
board. Beginning at the Controller; it is always connected from the Output (J5) to the
Input (J1) of the next enclosure.
RS485 SYSTEM DIAGRAM
Flash Head Connection
The connection between the Flash Head and the Power Supply requires an 8 conductor
cable.
NOTE: This is the only connection to the Flash Head that is required.
WARNING: If the cable is not color coded or numbered the instructions state the
installer must take notes of wiring to ensure that both the Flash Head and Power supply
get wired the same. If for example wire 1 is inserted in to location 4 by mistake severe
damage could result to the LED’s in the flash head. This will VOID all warranties.
Pin 1 or RED in the flash head must go to Pin1 RED in the power supply and so
on.
NOTE: The installer should provide this information to the site manager upon
completion for future reference when required

System Installation Requirements for EMC and Lightning Immunity:
1: Ensure the shield of the cable that connects the Flash head to the power supply is
grounded at both ends. Make 360-degree ground connections around the braid or foil
(avoid pigtails).
2: For increased lightning protection adding a lightning rod that extends up 3 feet above
the fixture and 18 inches away from the light is recommended.
3: The drain-wire in the Flash Head cable must be connected to ground at both ends.
Ensure that the wire is short as possible and avoid loops.
4: Ensure the Flash Head is electrically bonded to the tower. Scrape away access paint/
powder coating as necessary.
5: Minimize loop areas by tying all cables against the tower or passing through conduit.
6: Ensure the Power Supply enclosure is electrically bonded to the tower. Scrape away
access paint/ powder coating as necessary.
7: Ground any spare/unused conductors in the Flash Head connection cable at both
ends.
8: It is recommended that a minimum of ¾” conduit is used for all wiring ways.
9: RS485 connections must be secure and shield or braiding must be grounded
securely.
Power Supply Specifications & Electrical Parameters:
Flash Rate for L864/L865
The Red Beacon factory setting is 30FPM (Flash per minute).
The White Strobe factory setting is 40 FPM (Flash per minute).
Fault / Alarm Connections
There are NO additional fault connections required in the Power Supply enclosure. All
faults are sent to the Base controller via the RS485 communications.
NOTE: It is vitally important that the RS485 connections are checked and secured.

Configuration Option Switches
NOTE: In previous versions of the Dialight D1RW there were settings required for the
dip switches on the micro board.
This version only requires position 1 of SW1 to be used.
If being used as a Dual red and white beacon the micro board switches SW1 must be
set to the off position.
If being used as a White only system then SW1 position 1 should be set to the on
position.
NOTE: The switches are factory set to the off position and positions 2, 3, & 4 should be
checked that they are set in the off position.

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 red indicator LED’s have gone out.

Strobe White Driver Diagnostic LED’s
The two Strobe White Driver modules each have three indicator LED’s.
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 LED’s in the Flash Head do
not operate yet these diagnostic LED’s do blink, this would indicate the fault is not with
the Driver module. Should one or more of these LED’s 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.
Red Beacon Driver Diagnostic LED
LED 1: Indicates more than 50V is present on the output and gives a good indication
that the Beacon Driver module is working.
Microcontroller Board Diagnostic LED’s
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.
NOTE: Verification of the above may only be required if a communications Alarm is sent
to the Master Controller
Translator Board Diagnostic LED’s
When power is applied to the Power Supply there are 3 LED’s labeled ISO 5V, 12V and
5V that must be solidly lit. The LED labeled Watchdog must be blinking.
Once communications from the Master controller has been established there 3 LED’s
that will Blink in unison.
These are TX_EN, TX 1 and RX 1
NOTE: If these are not blinking then there are no Communications.
NOTE: SW1 must be to set to position 0 when used as an AOL
