SIMPLE STATION STOP

  
       
Products/Index New Products Prices & Sales Home
The SIMPLE STATION STOP is designed to halt a train at a station or any other desired place, where it will wait for an adjustable time and then restart.
The SSS (SIMPLE STATION STOP) switches the track power off and on to stop and start the train. This is realistic for trains running at slow speeds. At high speeds this results in sudden stops and starts. If controlled deceleration and acceleration are required please refer to our SA8 and SA8-S.
The SSS combines an infrared sensor and a circuit for stopping the train and timing the train stop.  The SSS is positioned under the baseboard at the place where you want the train to stop.
Two wires are required to connect power to the circuit board and a further two wires connect the circuit board to the track.
POSITIONING THE SSS
As soon as the infrared detects the train the SSS will switch off the power to the track. The unit will therefore need to be positioned where the leading end of the train is to stop. The leading edge of the train may move a little past the detector due to inertia or effects of flywheels.
The train restarts after the timing interval even though it is still being detected. There is a dead time of 12 seconds before the SSS will operate again. This is to prevent the end of the departing train activating it.
INSTALLATION
The installation of the circuit board on the baseboard is the same as the installation of an IRDOT.
As the name implies connections to the circuit board are simple. Two wires connect the power source to the circuit board; two wires from the circuit board connect to the track
POWER SUPPLY
The SSP can be powered from 12 to 16 volts either AC or DC.
TIMING
Timing of the stop time is adjusted by rotating the “pot” on the SSS board with a small screwdriver. The timing can be adjusted between 12 and 120 seconds.
SIGNALS
There is an option to operate a 2-aspect starter signal provided on the SSS board. The signal will show red for stop, change to green for depart and remains at green 5 seconds after the last part of the train has cleared theSSS unit. A 2-aspect common negative LED signal is suitable.
Full details for this are included in the Instructions.
