BTM-SG-G Booster Separation Point Module
from the Digital-Professional-Series!
BTM-SG-G LDT-Part-No.: 780503
> > finished module in a case <<
Suitable for all digital formats, for all Command Stations and all
DigitalBoosters
This module provides a secure electrical separation of booster current
circuits via a switch-over track and two sensor-tracks (three isolated track-
sections).
The switch-over track section between the two sensor-tracks shall have at
least the same length as the longest train on the layout.
This product is not a toy! Not suitable for children under 14 years of age!
The kit contains small parts, which should be kept away from children under 3!
Improper use will imply danger or injuring due to sharp edges and tips! Please
store this instruction carefully.
Introduction / Safety instruction:
You have purchased the Booster Keep Separation Module BTM-SG for your model
railway layout.
The BTM-SG module is a high quality product that is supplied within the
Digital-Professional-Series of Littfinski DatenTechnik (LDT).
We are wishing you having a good time using this product.
- Please read the following instructions carefully. Warranty will expire due to damages caused by disregarding the operating instructions. LDT will also be not liable for any consequential damages caused by improper use or installation.
- We designed our devices for indoor use only.
The BTM-SG module comes as finished module and as finished module in a case with a 24 month warranty.
Connecting the Booster Keep Separation Module BTM-SG to your digital model railway layout:
- Attention: Before starting the installation switch off the voltage supply by pushing the stop button or better disconnect the main supply.
The Booster Keep Separation Module BTM-SG receives the power supply via the clamp KL6. The voltage of 16…18V~ of a model railway transformer (ac output) is cceptable.
Operation mode:
Each booster supplies current for an own rail section. The rail sections have
to be electrically isolated against each other by separation sections.
If a locomotive passes a separation section the electrical isolation will be
temporary cancelled. At the 3-conductor track will this be caused by the
sliding contact of the locomotive. At the 2-conductor track this will happen
if the locomotive has more than one axle with sliding conductor.
During the electrical bypass of a separation section some balance current can
flow over the loc. Through the whole train if the train contains conductive
couplings and sliding
conductors at the train front and end.
Related to the level and duration of the balance current flow it can cause
damage to the boosters, the locomotives, the conductive couplings and the
rails.
The Booster Keep Separation Module BTM-SG provides a secure electrical
separation between the booster current circuits. For this separation will get
the isolated switch- ver track which is situated between the two booster
current circuits the supply from one competent booster only.
Suitable to the drive direction of the train the digital current supply of the
switch-over track will be switched automatically under the travelling train
onto the competent booster.
The Booster Keep Separation Module BTM-SG indicates the travelling direction
of the train within two isolated track sections (so-called sensor-tracks) at a
length 5 to 20 cm
(optimal). Between the sensor tracks shall the switch-over track situated
which has to have at least the length of the longest train on the layout.
Both rails of the sensor tracks 1 and 2 and the switch-over track have to be
isolated and connected to the corresponding marked clamps of the Booster Keep
Separation Module BTMSG.
The digital voltage of both boosters which are competent for the separation
point shall be connected to the clamps booster 1 and booster 2.
The Booster Keep Separation Module BTM-SG is able to switch a digital current
of up to 8 Ampere.
The Booster Keep Separation Module BTM-SG is able to work without any problems
with boosters of various manufacturers and with various electrical
characteristics combined on one model railway layout.
