6.4 Connecting the signal inputs

For the BM2 to learn the signal status, the BM2 signal inputs will have to be wired correctly.
The signal inputs are voltage-controlled. If no voltage is applied to the signal input "Stop", the train
will stop before the signal. If voltage is applied to this input, the train can pass, continue after a stop
or slowly approach.
If voltage is applied to the signal input "Slow approach", the train will slowly pass.
The "Clear" input has priority over the "Slow approach" input. Therefore, if no voltage is applied to
the "Clear" input, the train will be stopped in any event, even if voltage is applied to the "Slow
approach" input.
You can use a control voltage between 8(AC)/11(DC) and 24(AC/DC).
6.4.1 Using light signals
Simply connect the BM2 signal inputs to the bulbs of the light signal. When the light signal is set,
the BM2 will know how to react.
Connect the signal input "Clear" to the green bulb of your light signal. This way, the signal input is
self-securing: A train can only pass if voltage is applied. This means that if the power supply of the
signal fails, the train will be stopped.
If you also want to use the signal input "Slow approach", simply connect the respective terminal to
the yellow bulb of the light signal. Note: If voltage is applied to this input, the BM2 will ensure that
the passing train is slowed down to slow approach.
The "Clear" input has priority over the "Slow approach" input. Therefore, if no voltage is applied to
the "Clear" input, the train will be stopped in any event, even if voltage is applied to the "Slow
approach" input.
