Combining the track outputs of the MX10,
or
a number of MX10s in a Master-Booster arrangement
SW July 2018 - SW 01.24 and higher
If the “normal” track output of the MX10 (“Schiene 1” (track 1) or “S1” with 12 A traction current) is not
enough to supply the layout, frankly, there are two possibilities: interconnecting the two track outputs
(“S1” and “S2” with configuring “SYNC” in “MX10 CONFIG”) to a power circuit of about 20 A, or the us-
age of booster devices (specially configured MX10).
Interconnecting the MX10’s outputs (picture on the right):
The outputs “S1” and “S2” are interconnected (caution with N-P polarity), and together form the con-
nection point for the layout. In the menu “MX10 CONFIG”, -> “SYS MODE”,
“SYNC”
is set. This
means that all running voltages (only adjustable in combination) and “STOP & OFF” states are auto-
matically set on the same level.
But the track outputs shall not be connected directly, the connecting cable has to have a
MINIMUM RESISTANCE of
0.01 Ohm.
This can be guaranteed by a certain cable-length.
0.5 m stranded wire with a 0.75 mm
2
cross-section correspond to about 0.01 Ohm
1.5 m stranded wire with a 2.5 mm
2
cross-section correspond to about 0.01 Ohm
2.5 m stranded wire with a 4.0 mm
2
cross-section correspond to about 0.01 Ohm
Attention: the MAXIMUM resistance shall be
0.1 Ohm
because otherwise the cur-
rent equalization between the two outputs would no be possible due to the auto-
matic voltage variation. This leads to the recommendation:
Typical cable between “S1” and “S2”: 1 - 2 m long
Master-Booster operation:
Up to 16 MX10 (or MX10EC) can work together as boosters with one MX10 (or MX10EC) as
digital command station.
Each MX10, both master (digital command station) and booster, has to be supplied by a po-
tential-free power supply unit. We recommend ZIMO’s power supply units of 240 W or 600 W
(with real booster operation usually the more powerful one).
In the booster’s menu “MX10 CONFIG”, -> “SYS MODE”,
“B1”...”B16”
is configured. Each
booster device gets its own number. The system central command station keeps the configu-
ration “MASTER”.
The boosters are automatically synchronised with track output S1 of the central device;
thereby also BCS (broadcast stop) and OFF states are synchronised. As service mode pro-
gramming track, exclusively track output S2 of the central MX10 (Master) can be used.
Note: due to the fact that track 1 and track 2 are equivalent, modules like the StEin can also
be supplied by the track voltage of track 2. Still, you have to take the programming track func-
tion into account.
