• The terminals labeled Trafo supply energy to the decoder. These
terminals are either connected to the digital signal as well (as
shown on the right) or to an external AC or DC voltage between 12
and 18 V (left).
• Connect the turnout drives to the terminals labeled "Weiche 1" to
"Weiche 4".The turnout drives are connected as follows:
Motors are connected to terminals
and
.
Turnout drives of LGB or Piko are wired the same way.
Using a Conrad motoric turnout driver connect both brown cables to one terminal
of the decoder and the red one to the other terminal.
Connect both the yellow and pink cable of Tillig turnout drivers together to one
terminal of the decoder and the red cable to the other terminal.

There is no short circuit protection between the decoder outputs
and the track signal! Short circuits can destroy the decoder.
Switching of motoric drives with only one decoder output and the track
signal is not possible with a Z2-8N. Use an Z2-8 (continous mode) or a
Z2-8+ (also in pulse mode) instead. Switching of turnouts with an extra
key button in parallel to the decoder output is not possible with a Z2-8N.

5. If the decoder accepted a valid digital command the LED will
switch off. The decoder is now in the normal operation mode.
The Z2-8N is factory programmed to accept DCC commands and
switches the outputs with the addresses 1-4 with a duration of

Overload and short circuits
Qdecoder are protected against short circuit and over current
at the outputs. If the current rises above 2 A the outputs of the
decoder will be switched off and can only be reactivated after
resetting the decoder.
In case of an over current the LED flashes once for each function
output (A0 to A7) and afterwards stops flashing. Short flash
pulses show non-critical outputs, while long flash pulses indicate
an output, which should be checked.
In this case do the following:
1. Check and remove the cause of the short circuit.
2. Press the programming button briefly or use the stop button
on your digital control to restart it. The configuration of the
decoder will not be changed.
