Assembly of LEDs: Insert LED cables from
above into pole. Press LEDs into cover (1)
so that cables extend to either side of cover.
Fix LED and cover to top and adjust if nec-
essary (pull cables slightly). When all parts
are adjusted, remove cover and apply some
glue. Then press back into position. Finally
glue bow (6) to cross from underneath.
Soldering of switch
Picture 4 indicates individual positions of
electronic parts. Start with resistors and
diodes by bending wires to fit into drilled
holes of base and apply resistors and di-
odes according to pic. 4.
Caution! Diodes are marked on one end
(black marking). Make sure to place items
in proper direction following layout (pic. 4).
Solder all inserted parts from rear side of
base, cut away remaining wires. Apply
transistors (13) in same manner before
putting elkos in position. These parts are
also marked appropriately and the shorter
wire is your negative pole. Regard proper
polarity.
Finally place power connecting cables
(brown/yellow) into position and solder to
copper plating on rear side of base.
Connection of blinkers to switch
Caution! Never place base on tracks or
other circuit lines - danger of hazard!

Picture 5 indicates proper connection of
blinkers and switch unit. Both blinkers must
be connected simultaneously. If no func-
tion is achieved, power connecting wires
must be exchanged. Since heat is generated
during operation, sufficient air ventilation
should be provided.
Switching -off and -on of blinkers
Continuous function of blinkers is achieved
when switch is connected to power unit.
Crossing blinkers may be switched off and
on manually by use of contact switches
(Busch #5706) or automatically by use of
a relay operated by two track contacts. For
remote control function it is necessary to
connect the brown cable directly to power
unit while yellow cable must hold a switch
or relay.
A more comfortable and convenient
method is achieved by use of Busch IR-
units in connection with a timer (Busch
#5961). When IR-beam is interrupted by a
passing train a timer receives an impulse
activating the crossing blinkers. The timer
de-activates blinkers after a certain unit of
time (ranging from 2 - 24 seconds). If a train
stops between IR-transmitter and IR-re-
ceiver, blinkers will remain active until train
departs.
