Stand-by current:	<0.1W
Trigger voltage positive:	6-30V DC
Trigger voltage ground:	Min. 6V DC below supply
Trigger current:	Max. 6mA
Cable diameter	0.25mm2 to 3.0 mm2 (12 to 24AWG)
Relay voltage:	Max. 24V DC
Relay current:	2A Max.

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 first remove the hexagon m3 bolt, then unscrew the glass top of the housing. To wire, the ATEX Beacon removes the LED insert by removing the 3 Nylon screws and disconnecting 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 analog or controlled by Modbus.

Analogue Controlled

Select if the trigger is a positive or negative trigger by setting the Jumper to the right position. Select the mode and patterns for each used color by according to the DIP switch settings figure. Connect the trigger wires to the correct terminal. NOTE: Colours are prioritized Lowest blue>green>yellow>Red Highest, so if you trigger green and red you get a red light.

When connections are made reconnect the LED PCB to J3 and fix it with the 3 nylon screws. Carefully screw back glass to ensure that there are no cable obstructions during the closing, place back the hexagon bolt.

Modbus Controlled

4.1 SETTINGS
The following configuration options are available with the dip switches.

Option| Default value| Valid range| Description| DIP Switch
---|---|---|---|---
Modbus ID| 0 (disabled)| 1-255| Select Modbus address| 5/12
Baudrate| 9600| 9600-19200| Baudrate in symbols per second| 2

4.2 SUPPORTED CODES

Function code	Function name	Used for
3	Reading holding register(s)	Reading registers ( up to 8 registers per

command)
6| Write single register| The setting of a register
16| Write multiple registers| The setting of multiple registers

Register Map

Data can be read using the Read Holding Registers command. A memory map de- tailing all useful locations is listed below:

Address	Content	Unit
Ox0000	Light effect type	View note [1]; 16-bit unsigned integer
Ox0001	Red value	View note [2]; 16-bit unsigned integer
0x0002	Green value	View note [2]; 16-bit unsigned integer
0x0003	Blue value	View note [2]; 16-bit unsigned integer
0x0004	Relay control	Zero: disabled, non-zero: energized
0x0005	Input status	View note [3]; 16-bit unsigned integer
0x0006	Firmware version

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 larger than 255 is internally set to 255. [3] This register reflects the status of the input pins. The pins do not control anything but can be used to read the status of external equipment.
5.1 PIN NUMBERS
The input status register reflects the value of the input pins. Toggling these pins while the unit is configured as a Modbus device does not affect the operating behavior.

Bit	Decimal value	Pin
Bit 3	8	Red
Bit 2	4	Green
Bit 1	2	Blue
Bit 0	1	Yellow

5.2 LIGHT EFFECT TYPES
The input status register reflects the value of the input pins. Toggling these pins while the unit is configured as a Modbus device does not affect the operating behavior.

ID	Effect
0	Slow flashing (3Hz 50% duty)
1	Looping effect 1
2	Looping effect 2
3	All leds continuously on
4	Looping effect 3
5	Flashing (2Hz 10% duty)
6	Flashing (10Hz 50% duty)

Troubleshooting

Error	Solution
The beacon will not turn on	Check power supply

Check trigger input
Check connection cable from letting insert to J3 to ensure is connected
Check if the trigger jumper is installed correctly
Wrong color| Check if the correct trigger is pulsed
Is there a higher priority trigger active ( Blue>Green>Yellow>Red)
Beacon runs color pattern automatically| Disable demo mode
No response on triggers| Check if the beacon is set to analog mode
