DZ-1040/
1050/ 1060/ 1080 Instructions
The signal only needs the RED wire connected to power (12-18V
AC or DC) and the BLACK wire connected to common. Place the signal next to the
track about ¾” away from the outside rail. Facing the front of the signal,
the train is detected on the LEFT side. The sensor will not reach across more
than one track. If more sensitivity is needed to detect black rolling stock, try
rotating the sensitivity adjustment clockwise.
When the train passes the signal, the indication will change to RED or
stop and hold until the train has passed. 4 seconds after the train passes, the
signal will change to YELLOW or caution. Then, after 2-3 more seconds, it will
change back to GREEN or go.
The signal only needs power to operate, but it does have an
input (YELLOW) and an output (WHITE) for additional possibilities.
OPTION A – If the WHITE wire of a signal down-track is
connected to the YELLOW wire of an up-track signal, the up-track signal will
hold on caution (YELLOW) until the down-track signal goes off stop (RED).
 OPTION
B
– The WHITE wire can be connected to the GREEN wire of a DZ-1008 relay module.
The RED wire of the DZ-1008 should be connected to the same power as the signal
and the BLACK wire connected to common. The signal will then cause the relay to
change when the signal goes to stop (RED) and the relay will change back when
the signal goes off stop to caution (YELLOW).
OPTION C – If the sensor is covered with black tape,
then the input (YELLOW) wire can be used to control the sensor. Connecting the
input wire to common will cause the signal to indicate stop (RED).
With the wire not connected, the signal will time-out and go to yellow,
then green.
