Once triggered by the train, the module runs built-programs. ( black surface will absorb most IR light, you may stick white tape under the train or use track side sensors ) 1, to simulate the operation of 2-, 3- or 4-aspect signals. signals normally show green. When the train passes the detector, the signal switches to red and keep red. Once the train has fully cleared the detector, the module switches the signal back to green (via delay red, yellow and double yellow if appropriate). 2, stop and restart train before the rail spur. When the train passes the detector, the signal switches to red and keep red, the slave board will cut off power to the near tracks so that no train can get through the near tracks, Once the train has fully cleared the detector, the module switches the signal back to green (via delay red, yellow and double yellow if appropriate), and slave board power the near tracks again so that the near train can restart. 3, stop the train and restart it at station or let the train run back. When the train trigger the detector, the slave board will cut off the power to the tracks and stop the train, after the set time, it will power the tracks again and the train will restart. Or run to another direction under shuttle mode. 4, trigger the crossing signals’ sound effect board, flasher board, servo for gates or other devices When the train passes the detector, the master board provide power to the sound board/flasher board, Once the train has fully cleared the detector, wait for delay time if appropriate, then it cut off the power to them, work for both directions.
