BLOCKsignalling Simple Shuttle Train Controller with Adjustable Delay SS1
The BLOCKsignalling Simple Shuttle is designed to automate a DC model train running backwards and forwards along a single length of track, providing a waiting time at each end of the line which is slightly randomised to provide a more realistic operation.
At each end of the track, a diode is fixed across an insulated rail gap to stop the train until the track current is automatically reversed by the module and the train will start traveling in the opposite direction.
The time between each change in current direction can be changed by a simple screwdriver adjustment. The delay time for each direction is adjustable between 1 second and 10 minutes.
Each of the relays are rated at 10A for long life (traction current is typically 0.5A to 1A).
The required diodes are included
Power Supply:
The module operates from any DC supply in the range 8V DC to 25V DC, or any AC supply in the range 8V AC to 16V AC. If the track voltage is above 8V DC, then the module can be connected to the track power supply.
DCC track power can also be used to feed the module.
Timing Adjustment:
The timing is adjusted with a small screwdriver, which fits into a slot in the adjuster mounted on the PCB. The adjustment is very fine for the first half of the rotation, setting the timing between 1 second and 90 seconds, then becomes more coarse up to the maximum setting of 10 minutes.The module reads the setting when the power is applied, and each time the relays are switched. Generally, it is easiest to set the approximate time using the diagram above, then switch off the power for 10 seconds or so. When the module is re-powered, it will read the setting and commence its operation. Minor adjustments can be made whilst the unit is running, and they will be used at the next opportunity.
Other Ideas (see instructions below):
You can use one low cost speed controller to run several shuttle units, providing they are within the capacity of the controller.
Trains can be operated at different speeds by inserting one or more diodes in the feed to the track. Each diode has an approximate 0.7V voltage drop.
Use a different number of diodes in each direction to create different speeds in each direction. You need at least one diode for each direction.
Creating additional track gaps, with associated diodes, allows differing voltages along a length of track, and so different operating speeds in each section.
Use one diode in each direction to drop the speed in the following section by equal amounts.
Use a different number of diodes in each direction to create different speeds in each direction. You need at least one diode for each direction.
Speed reductions can be removed by shorting across the diodes with a switch.
Different stop points can be created by inserting additional single diodes, and shorting across them when they are not required.
