Lenz 22620 - Block section module BM3

The BM3 is a block section module that uses ABC technology for braking and stopping. With it a prototypical block route operation is possible. The number of blocks is not limited as a BM3 is used for each block. The BM3 has a connection for light signals * to display the status: red signal = next block occupied, BM3 is switched to "Halt", green signal = next block free, BM3 is switched to "drive". The last block of a non-circular sequence of block sections requires a BM2 instead of a BM3, which releases the last stopping section either manually (signal, button) or automatically. * The BMA adapter is required to control signals with double coils (or motors).
