Dividing the layout
8.6. RailCom®
If the ECoSBoost is used as described in section 8.4., the detection
and generation of the RailCom® cutout gap can be activated on
request. Here, remove the transparent cover as shown in Fig. 10
and insert the left jumper if the RailCom® cutout gap is to be
used.
8.7. current limit
If command stations with CDE interface are connected, the maxi-
mum current can be limited to 4A by removing the right jumper
shown in Fig. 11. This setting is ignored when operating on an
ECoS control center, where the maximum current can be set on
the software side.
9. Dividing the layout
To ensure a trouble-free operation of your layout, proper planning
of the track sections is essential. We are glad to assist you here
with some ideas.
9.1. Power section
Please consider the arrangement of the power sections very ca-
refully! Assign the transitions between each of the single booster
sections in a way they are rarely passed by trains.
The following divisions are useful:
• Station / Depot
• Mainline (probably divided in several sections)
• Side/branch-line (probably divided in several sections)
Regardless of the size of each single circuit, there should be a cur-
rent supply from the booster to the tracks every 1.5 – 2 metres: as
the transition resistance of the track sections is not negligible, the
omission to feed the tracks every 1.5 – 2 metres may lead to a fai-
ling short-circuit detection due to voltage drops within the tracks.
If vehicles, which are far away from the feeding point slow down,
it is – in most cases - a sign of insufficient power supply.
Each circuit needs to be separated by a single-pole isolation. This
means to disrupt the contact studs of three-conductor tracks and
at least one of the two-conductor tracks.
We recommend only using boosters of the same type. In a mixed
operation it is likely that problems may occur whenever a loco-
motive crosses a district boundary due to a greatly varying time
related behaviour and track voltage.
If a mixed operation is, however, unavoidable, it must be noted
that a rocker contact for separating the centre rail is required at
the district boundaries.
Furthermore, the track voltage of every district boundary should
be as high as possible and at the same level.
Please make sure that locomotives or trains do not stop directly
on a joint and bridge two district boundaries. Hereby, the outputs
of both boosters will be electrically connected. Depending on the
layout of the boosters and, respectively, their supply voltage equa-
lizing currents might flow which will lead to the destruction of the
booster after some time.
9.2. Separate circuit for magnetic accessories
For larger layouts we recommend to use another booster to switch
all the magnet accessories separately. In this way it will be still
possible to switch magnetic accessories, if the track is powered
off, e.g. by a short circuit. This will increase the operating safety
significantly.
9.3. Transition from digital into analog sections
With a transition from a digital section into an analogue supplied
section there are certain things you must pay attention to. The
track separation as explained in chapter 8.3. will not be sufficient
here.
You have to isolate the digital part of your layout from the ana-
logue on both sides at the transition points in order to avoid an
electrical contact. To do so, please either use isolating track con-
nectors or saw the track profiles.
