Specifications

The FLASHER circuit is completely solid state and operates with either AC or DC input power.
Each of the two outputs can handle up to 3 ampere of current so it is possible for the FLASHER to illuminate several
crossing lights at the same time. The FLASHER has an adjustment potentiometer allowing the flash rate to be varied to
suit the users preference. Typical range is from 1 - 3.5 Hz (1 - 0.275 second).
A simple on-off switch in the "INPUT" or "COMMON" connection can be used to manually activate the FLASHER. For
automatic operation with 3 rail track, insulate a section of one outside rail allowing the wheels and track to function as
the switch in the "common" (instructions illustrating this installation included with Flasher). It is also possible to use
TRAK-DT, TRAK-DTT, TRAK-DTT2, TRAK-DTL, OPTO-DT, or similar items as a switch to turn on the FLASHER.
Multiple crossbucks would be wired in parallel to each other. A single crossbuck is shown for ease of wiring instructions.

Crossbuck wiring using LED's
LED's are current type devices, not voltage devices like light
bulbs. Therefore you have to use a limiting resistor to operate
the LED's. Otherwise you will burn out the LED's. Since only
one LED is on at a time, only one limiting resistor is required for
one crossbuck. Values shown are for RED LED, item 532.
The "input Vmax" shown is for the opeating voltage of the
Flasher (item 367), or Grade Crossing Controller with Bell
Sound (item 587) units.
Only 1 resistor is needed per pair of LED's since only one is on
at a time.

Crossbuck shown has the "common" terminal in the center. Some crossbuck's may
have the "common" connection on one end instead of the middle. If the lights don't flash
alternately, then you don't have the common wire connected to the common of the
crossbuck lamps.
Wiring 3-Rail track
for automatic operation
Wiring the Flasher for automatic operatoin with 3-rail track
requires using track that has one outside rail electrically
insulated from the other outside rail. Most modern track with
either wood or plastic ties has the outside running rails
electrically insulated.
Although there is only one connection shown for the "Variable
AC", as well as the "Track common", to the track, it is best to
have more than one power feed for all layouts. It is also a good
practice to wire the track common to the opposite outside rail
for better operation, as shown.
