Changing the Flash Pattern

LIGHT HAZARD: To be an effective warning device, the beacon produces
bright light that can be hazardous to your eyesight when viewed at close
range. Do not stare directly into the light at close range or permanent
damage to your eyesight may occur.
EXPLOSION HAZARD: To prevent ignition of hazardous atmosphere,
disconnect the device from the supply circuit before opening it. Do not
open the device in the presence of explosive gases in the atmosphere.
BURN HAZARD: The LED emitter gets hot enough to burn you. Always
allow the emitter to cool before handling it.
The Model G-LED Series beacon has eight flash patterns that are selected by
setting a DIP switch on the PCB. See Figures 9 and 10 on page 19.
Tools needed:
• 1.5 mm A/F hexagon key
• 2 mm blade-tip screwdriver
• No. 1 Phillips screwdriver
To select a pattern:
1.
Disconnect power to the beacon.
2.
Unscrew the M3 set screw on the side of the housing one full turn.
3.
Remove the lens cover from the housing by turning the cover counter-
clockwise. Three 120-degree spaced reliefs are provided for a spanner
wrench if needed. If the cover assembly will not unscrew, back out the set
screw a few additional turns
4.
Loosen the captive Phillips screw retaining the printed circuit board (PCB),
and slide out the PCB until DIP switch SW1 is accessible.
5.
Select a flash pattern by setting the DIP switches on SW1. Steady On is
the default.
6.
Insert the PCB assembly into the enclosure and fully tighten the captive
screw.
