8) Flash Pattern Settings
8.1. Flash Rate Setting
The STExB2 beacons can produce different flash patterns as
shown in Table 3. The flash patterns are selected by operation
of the flash setting DIP switch on the PCBA (See Fig 6).

9) End of Line Monitoring (DC Units)
All DC units have a blocking diode fitted in their supply input
lines. An end of line monitoring diode or an end of line
monitoring resistor can be connected across the +ve and –ve
terminals in the flameproof chamber. If an end of line resistor
is used it must have a minimum resistance value of 3k3 ohms
and a minimum wattage of 0.5W or a minimum resistance
value of 500 ohms and a minimum wattage of 2W.
The resistor must be connected directly across the +ve and -
ve terminals as shown in the following drawing. The resistor
leads should be kept as short as possible.
Figure 7: End of Line Resistor Placement.
10) Interchangeable & Spare Parts
The beacon lens is interchangeable, contact European Safety
Systems Ltd for a replacement lens available in various
colours.
The guard is an integral part of the protection and must be
reassembled exactly the same way as it was disassembled.
To change the lens, unscrew the M5 socket head screws and
remove the M5 screws, M5 spring & flat washers.
Figure 8: Removal of Lens.
Remove the guard and replace the old lens with the new lens.
Warning – Hot surfaces. External surfaces
and internal components may be hot after
operation, take care when handling the
equipment.
Warning – high-intensity light source.
Avoid looking directly at the light source for
extended periods of time.
