Digital centre
2.3 Power Supply for the
z
21
start digital centre
As a power supply for the
z
21
start digital centre, please use exclusively the supplied AC adaptor or
the AC adaptor Art. No. 10851. Positively do not use a wound-core transformer!
The
z
21
start digital centre is designed for loads of up to 3.2 A. If frequent power cuts occur in the
system due to overloads, please install a booster (see Page 44).
Note: To find out the current power consumption of your system, check the menu point “Power
Centre” in the “Z21 Settings” menu of the Z21 mobile app*.
2.4 Operation of Digital Locomotives
The
z
21
Digital System is suitable for the control of all locomotives using Roco loco decoders or any
DCC-compatible decoders. Your
z
21
Digital System can administer up to 9,999 loco decoders.
The preconfiguration by the factory of all Roco and Fleischmann locos is decoder address 3. If you
use several locos on your system simultaneously, you need to assign a separate decoder address to
each one. Further information is available in the multiMAUS handbook.
With the
Z
21 mobile app*
, this is very simple: put the locomotive as the only loco onto the track.
Select the locomotive on Z21 mobile app* and give it a name and decoder address not yet assigned
in the programming mode. That’s it!
All magnetic items (switches, decoupling tracks, signal decoders) equipped with a digital decoder
can be programmed and controlled with the Z21 mobile app* just as easily.
Note: How to compute the power
consumption of an H system:
Stationary locos with light:
approx. 100 mA
Travelling locos depending on
size and load: 300 – 600 mA
Illuminated coaches: approx. 30
mA per minibulb (expect consi-
derable fluctuations!)
Digital coupling or smoke gene-
rator: approx. 100 mA
Digital switch drive or switch
decoder: approx. 500 mA as
reserve
Warning: Positively do not con-
nect the
z
21
start digital centre
to Roco amplifiers Art. Nos.
10761 and 10764! Use these
components only on electrically
separate layout parts connected
only by transition tracks.
