Lenz Elektronik Digital plus BM1 Owner's manual

Information BM1
Not suitable for children under three because of
the danger of their swallowing the small
constituent pieces. Improper use can result in
injury from functionally necessary points and
edges. For use in dry areas only. We reserve the
right to make changes in line with technical
progress, product maintenance or changes in
production methods. We accept no responsibility
for direct or indirect damages resulting from
improper use, non-observance of instructions,
use of transformers or other electrical equipment
which is not authorised for use with model
railways, or transformers or other electrical
equipment which has been altered or adapted or
which is faulty. Furthermore, we accept no
responsibility for damages resulting from
unsupervised modifications to equipment or acts
of violence or overheating or effects of moisture
etc. In all such cases, guarantees shall become
void.

technology
To combine ABC technology with the
BM1, BM2 and BM3 block section
modules, you will need to use Digital
plus GOLD series locomotive decoders
or other decoders that support the ABC
technology.
3 How does the BM1 work?
With little effort, ABC manages to
accomplish just what model railway
enthusiasts crave:
Exact stopping in front of signals and
passage in the opposite direction. By
means of simple modules which supply
the braking section in front of a signal,
the locomotive decoder receives the
signal status information: if the signal is
"red", the train will stop, if the signal is

"green", the train will continue
unimpeded.
Technically, this is realised as follows:
if the signal is "red", the BM1 module
creates an asymmetrical DCC signal
in the braking section. This is detected
by the new GOLD series decoders.
The result is a gentle braking of the
train until it comes to a halt, optionally
with the set braking delay or set
braking distance.
If the train is not to stop, but to
continue unimpeded or to start moving
again after the stopping time has
elapsed, the BM1 will simply be
bridged with a switch.

4 Installing the BM1
First, define the length of the braking
section in front of the signal. Keep in
mind that the fastest train on your
layout must be able to come to a
standstill within this section. Use the
feature "constant braking distance" of
the GOLD decoder. This will ensure
that all trains will come to a complete
standstill within the braking distance so
defined.
4.1"On the right means on the
right..."
...was a slogan on a motorway sign at
the end of the 1980s. It was meant to
remind drivers to change back to the
right-hand lane after overtaking a truck.
The same is true when using the ABC:
"on the right means on the right". It is
always the track that is on the right
depending on the direction of travel
that is separated when installing a
braking section.
Separate the right-hand track at the
beginning and at the end of the braking
section. Alternatively, you can use an
insulating track connector if there is a
track joint at the respective point.
Connect terminal "1" of the BM1 with
the right-hand track before the braking
section.
Connect terminal "2" of the BM1 with
the insulated braking section "A".
Use a switch parallel to the terminals 1
and 2 to switch the BM1 on or off. You
can use a signal switch to do this or
use an auxiliary set of contacts of a
switch machine. Many signals with
double-coil drive are also equipped
with a switch like this.
If you wish to use the BM1 in
combination with light signals, you will
have to install a relay parallel to the
green signal bulb. Use the make
contact of the relay to bridge the BM1
when the signal is "green".
