The 10765 Booster - Roco multiMAUS Manuel

The 10765 Booster

You require a booster if the system often switches off without the occurrence of a short circuit, i.e. no locomotive
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
or 10718), 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 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
▪
Digital coupling or smoke generator, approximately 100 mA
▪
If the power consumption exceeds 2.5 A, the section will be overloaded and will need to be divided up. You must
also make sure there are large tolerances in the current consumption, especially for light bulbs. Use the 42624
digital turnout drive or connect another turnout decoder directly to the drive circuit. You will then have to calculate
approximately 500 mA reserve for the switching current of the turnout.
If you have ensured that the system has a sufficient supply of power, the division of the booster sections is of no
significance 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 ROCO insulating rail connectors
42611 or 61192, insulated track or by sawing the rail profiles. Install a section of power track (e.g. 61190) in the new
supply section and connect it to the "Track Out" socket on the booster. Connect the booster to its transformer. Then
connect 10765 booster to amplifier 10764 with the special cable included in the box by plugging it into the socket
marked "Booster Out" on amplifier 10764 and the socket marked "Booster In" on 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
10765 boosters can be connected to the 10764 amplifier.
However, for large systems more than four 10765 boosters can be connected in conjunction with a 10779 braking
generator. The 10764 amplifier, 10765 booster and braking generator have to be connected in the following sequence:
10764 (or 10761) – 3 x 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 180°.
It is imperative that you make sure that the power track does not contain any capacitors.
