The Roco 10765 Booster - FLEISCHMANN multiMAUS 990001 Kurzanleitung

You can prevent this unwanted effect using a change-over section of track ( see fi g. 4 on page 63). It needs
to be as long as the longest train. It is double-pole insulated on both sides. The change-over section of
track is now monitored and changed accordingly by the separator module when the train passes over the
separating point. Drive operation on the rest of the system remains unaffected.

You require a booster if the system often switches off without the occurrence of a short circuit, i.e. no loco-
motive or carriages have derailed and there are no faults in the wiring. In this case, there is an overload
due to too many consumers (locomotives, illuminated carriages etc.). The booster connects an additional
transformer (Roco 10725), provides more energy and thus clears the overload.
Two boosters must not be connected to the same transformer! Each of these devices requires its own
voltage supply.
Connecting one or more Roco boosters 10765
Divide up the system into separate supply sections so that the number of consumers in each supply section
is as evenly distributed as possible. You calculate the power consumption in a section as follows:
• Stationary locomotives with light, approximately 100 mA
• Travelling locomotives from approximately 300 to 600 mA depending on size and load
• Illuminated carriages, approximately 30 mA depending on the bulb
• Smoke generator, approximately 100 mA
If the total power consumption exceeds 2.5 A, the section will be overloaded and will need to be divided
up. Notice also that there are large tolerances in the current consumption, especially for light bulbs. If you
connect the Fleischmann Receiver Module 6852 as a decoder for turnouts directly to the drive circuit, you
will then have to calculate approximately 600 mA reserve for the switching current of the turnout.
For more information on how to connect the Fleischmann 6852 Receiver Module, please see in the
appendix, section 'Hints, Tips and Help' on page 58.
If you have ensured that the system has a suffi cient supply of power, the division of the booster sections is
of no signifi cance to the reliability of commands, for drive operation or for switching turnouts.
Switch off the system before installing a booster. Divide the system into supply sections. Disconnect the
tracks electrically from each other in the respective places (on both sides!) wether using Fleischmann insu-
lating rail connectors 6433 (H0) or 9403 (N). Install a either a feed track (or connector clips, that come with
the start-sets) in the new supply section and connect the leads to the "Track Out" socket on the booster.
Connect the booster to its transformer. Then connect Roco 10765 booster to amplifi er 680801 with the
special cable included in the box by plugging it into the socket marked "Booster Out" on amplifi er 680801
and the socket marked "Booster In" on Roco booster 10765. Fig. 3 on page 62 shows the complete wiring.
If required, you can connect further boosters to the "Booster Out" socket of the 10765 booster. A maximum
of four Roco 10765 boosters can be connected to the 680801 amplifi er.
However, for large systems more than four boosters can be connected in conjunction with a Roco 10779
braking generator. The amplifi er, booster and braking generator have to be connected in the following
sequence:
680801 – 3 x (Roco)10765 – 10779 – 3 x 10765 – 10779 etc.
Make sure that the tracks have the same polarity at the change-over turnout so that short circuits are
not caused when a train passes over the separating turnout. If a short circuit occurs, turn the power
track plug (or leads) by 180°.
It is imperative that you make sure that the power track does not contain any capacitors.
