The
BLUE
wires of both crossing signals should be connected together. When power is applied, unless the two units have
been positioned as shown below, the lights will start to flash, the units will operate and the bell will sound. This is because the
light SENSOR on the DZ-1012 / 1022 / 1032 SLAVE needs to receive a signal from the IR LED on the DZ-1010 / 1020 / 1030
MASTER. The IR LED is on the back, top of the electrical box on the MASTER unit. If units are aligned as shown below, the
RED indicator lights will go out after a 6-8 second delay, the signal lights will stop flashing and the gates will go up. Breaking
the light beam from the IR LED to the SENSOR by your hand or a train car will trigger the units to operate. They will continue
to operate as long as the beam is blocked. It is also possible to activate the units by connecting the
BLUE,
the
YELLOW
or
the
WHITE
wires to
COMMON
. The DZ-1011 Block Signal Detectors operate this way. The
BLUE
wire will
HOLD
the gates
down and cause the LED(s) to flash. The
YELLOW
and
WHITE
wires will only
TRIGGER
the operation and the LED(s) to
flash, but after 6-8 seconds the operation will stop even if the wires remain connected to
COMMON
. This is so trains, which
are detected but do not enter the crossing, will not cause the continuous operation of the signals.
The two units can be
separated by
about
14 inches
.
DZ-1011 Installation:
The DZ-1011 Block
Signal Detectors add a
wonderful touch of
realism to your layout
and they provide early
detection of trains
approaching the
crossing. You may place
them as far up and down
the tracks as you like. As
shown above, they sense
the passing train on only
one side. Placing them
about ½ inch from the
edge of the track tie
should provide reliable
detection of all your
engines and rolling stock. The GREEN LED will switch to RED as the train passes and return to GREEN about 2-3 seconds
after it is gone. The wire functions of the DZ-1011 are shown in TABLE 1. Connect the RED wire to 12-14VAC and the BLACK
wire to COMMON. The WHITE wire should be connected to either the WHITE or YELLOW wires of the DZ-1010 or DZ-1012.
Since the DZ-1010 and DZ-1012
are connected together by the
BLUE wires, it is only necessary to
connect to one of the units. By
connecting the two DZ-1011
WHITE wires together, when one
changes, the other will also
change to indicate that the track is
occupied.
The Block Signal Detectors may
also be used separately to detect
trains or just as signals. If the
WHITE wire is connected to
COMMON, the GREEN LED will
go out and the RED LED will light.
