Grade Crossing Pro (GCP) Features:
Prototypical control of grade crossing signals (common anode/positive LED or bulbs) and gates
bullet An eastbound (left to right) train will cause the signals to begin flashing when sensor WF is covered. Approximately 1-2 seconds later the gate motor output will turn on and the gates will move down (if present). The signals will continue to flash even if it uncovers sensor WF as long as the train reaches sensor WN within 35 seconds. Assuming the train does this and then subsequently covers sensor EN the signals will continue flashing. Approximately 2 seconds after the last car of the train uncovers sensor EN the gate motor output will shut off and approximately 3 seconds later the signals will stop flashing. If the train had not covered sensor WN within 35 seconds of uncovering sensor WF then the GCP will assume the train has reversed. This “timeout” will cause the gate motor output to shut off and the signals will stop flashing (~3 seconds after gate motor shut off). Similar behavior exists for a westbound train with respect to sensor EF, EN and WN (shut off occurs after the last car uncovers sensor WN).
"TrueLamp" feature gives realistic flashing lamp persistence; the lamps (common anode/positive LED or bulbs) appear to fade out rather than simply turn on and off
Uses 4 sensors (included) for proper bi-directional behavior; each sensor has its own sensitivity adjustment and the GCP provides a setup mode for making the adjustment process easier
Adjustable gate motor speed
Cascade multiple GCP units for multi-track crossing arrangements. NOTE: Although it may be tempting to simply add additional sensors to handle a multi-track crossing, this will not yield correct behavior! The GCP would not be able to properly sense the direction of travel on different tracks!
Can also be triggered by other electronic circuits; trigger output can also be used to turn on a bell circuit (see below)
It is also possible to use current-sensing detectors rather than optical sensors; you can download an application note from our Documents section.
Works with all scales; signals and gates not included (use with products made by Tomar, Oregon Rail Supply, Walthers, NJ International, etc)
Photocell version powered from AC or DC; current draw is ~90mA with dual LED signals
