INSTALLATION
Do not handle internal electronical components whilst wiring up. Environmental
exposure during installation should be under dry circumstances, avoid heavy moist
and wet conditions.
To open the Housing please rst remove the hexagon m3 bolt, then unscrew the
glass top of the housing. To wire the ATEX Beacon remove LED insert by removing
the 3 Nylon screws, and disconnect the LED PCB from connector J3.
Connect Power Supply and signal or Modbus cables to the J9 or J4 connector. Se-
lect if you want to use the beacon analogue or controlled by Modbus.
ANALOGUE CONTROLLED
Select the if the trigger is positive or negative trigger by setting the Jumper to the
right position. Select the mode and patterns for each used colour by according the
DIP switch settings gure. Connect the trigger wires to the correct terminal.
NOTE: Colours are prioritised Lowest blue>green>yellow>Red Highest, so if you
trigger green and red you get a red light.
When connections are made reconnect LED PCB to J3 and x it with the 3 nylon
screws. Carefully screw back glass to ensure that there’s no cable obstructions
during closing, place back the hexagon bolt.

REGISTER MAP
Data can be read using the Read Holding Registers command. A memory map de-
tailing all useful locations is listed below:
Notes: [1] See table in next section for possible values in this register. [2] A value
0-255 will result in zero brightness (0) to maximum brightness (255). Any value lar-
ger than 255 is internally set to 255. [3] This register reects the status of the input
pins. The pins do not control anything, but can be used to read the status of exter-
nal equipment.
Pin numbers
The input status register reects the value of the input pins. Toggling these pins
while the unit is congured as a Modbus device does not aect the operating
behavior.
Light eect types
The input status register reects the value of the input pins. Toggling these pins
while the unit is congured as a Modbus device does not aect the operating be-
havior.
