Connection of accessory devices to the Z1
Î Light 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
conductor for the Z1 series. For ZH1 decoder the common return is applied
to the brown
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
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.

The two coils of magnetic drives are attached to the terminals

-output. If the turnout switches not as expected, change the terminals
accordingly. With semaphore signal drives the wire for the „stop" signal
