Simple wiring and operation
The BLOCKsignalling Simple Shuttle is designed to automate a DC model train running backwards and forwards along a single length of track.
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).
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 7V DC, then the module can be connected to the track power supply.
Please see pdf file below for the full wiring diagrams.
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.
PLEASE NOT THIS MODULE IS NOT SUITABLE FOR DCC OPERATION.
