(red/green) at DCC accessory addresses 1 to 4 (8 for Zx-16)
Z1 and ZH1 provide 8 or 16 equal and independently controllable function
outputs. They can be switched on and off with commands from the digital
control unit or with locally connected key buttons.
The decoder uses DC power to switch the connected accessories, regardless
of whether the decoder‘s terminals Trafo are connected to a transformer, a
power supply or the track signal.
The following pictures show the function principle of Z1 and Z1H. On the left
side the power supply and the track terminals and on the other side the
function outputs and the local supply terminals for accessories are depicted.
The Z1 operates a switch between function output and local ground whereas
the ZH1 switches the function output to the local supply. Accessory devices
of the Z1 are connected between function output and local supply, devices
for ZH1 are attached to function output and ground.

Connection of accessory devices to the Z1
ÎLight signals, single bulbs and LEDs
The lamps of a light signal are connected to the function outputs A0 to A7
(A15) of the decoder. The blue terminals are used as common return
conductor for the Z1 series. For ZH1 decoder the common return is applied
to the brown ground terminals. For a group of 4 function outputs a blue
and a brown terminal is provided.
Only every second “center terminal” between two function outputs is a
return conductor. The other ones can be used for applying switches, or
permanently switched on lamps
Using light signals with bulbs
dimming the brightness is possible
via programming CV‘s (CV 112, CV
122, ....) or reduce the brightness by
applying resistors.
It is mandatory to connect light
signals with LEDs using additional
resistors. In some cases these resistors are already included in the
signal socket. Operating LEDs without resistors may lead into immediate
destruction of the LEDs and signals.
For light signals with common anode a Z1 decoder is required. Light signals
with a common cathode are operated with a ZH1 decoder. Many light signal
manufacturers ship their models with a common anode.
ÎPermanently switched on lamps and LEDs

between the blue and brown terminals.
ÎTurnouts, relays and semaphore signals
The two coils of magnetic drives are attached to the terminals and
of output groups A0/A1 to A14/A15. Usually the -output switches the
turning track of the turnout, while the straight track switches with the
-output. If the turnout switches not as expected, change the terminals
accordingly. With semaphore signal drives the wire for the „stop“ signal
aspect is connected to the -output. The common return conductor of the
coils is connected to the -terminal. Two output pairs share one common
return. Using a ZH1 decoder the common return is attached to the brown
gorund terminal .

ÎMotoric turnout drives
Motoric turnout drives can not be controlled by a decoder of the Z1 or ZH1
series. Apply a Z2 series decoder instead.
ÎAdditional key buttons for switching turnouts etc.
Turnouts or semaphore signals can be switched
manually or automatically (train controlled)
by key buttons, reed relays or light barriers
attached in parallel to any function output
terminal. Applying the same principle lamps
or LEDs can be switched on by key buttons
attached in parallel to the function output.
Attach extra key buttons  to the brown ground terminals (Z1) or the
blue terminal (ZH1). Do not attach extra key buttons to the track signal
or other power supplys. You risk the destruction of the decoder.
When using additional key buttons we recommend to use turnouts with
limit stop to prevent excessive loads due to long switching pulses.
ÎEvaluation of key buttons etc
Decoder of the all-in-one class are able
to evaluate key button levels or reed
relays for the signal aspect generator.
The devices have to be attached using

Î Command 3 : Two-Aspect Block Signals (red/green)
The lamps of a block signal are connected to terminals and of an output
pair A0/A1 to A14/A15. The common return conductor of the signal is
attached to the blue terminal of a Z1 or the brown terminal of a ZH1.
The outputs are switched in light signal mode with fading of ¼ second.

for the second output is ignored. Opposing to the default settings the switching pulse
duration, the fade-in and fade-out times must be set for both outputs. This requires a
total of 6 to 8 CV write commands in opposite to the simple usage of the programming
button. This, however, will set up all function outputs of the decoder to identical
values (besides the address), which is not always desired.
