I have the OLD DZ 1010 crossing gates and the DZ 1011 Block Signal Detectors. They work precisely as the directions indicate. The Block Signal Detectors "trigger" the gates to go down but they do not and are not delivered to hold the gates down. Here is an excerpt from the directions...
The BLUE wires of both crossing gates (or 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 gates will go down and the bell will sound.
This is because the light SENSOR on the DZ-1012 (DZ-1022) needs to receive a signal from the IR LED on the DZ-1010 (DZ-
1020). The IR LED is on the back, top of the electrical box on the DZ-1010 (DZ-1020) 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 operate the units by connecting the BLUE wire or the
YELLOW or WHITE wirs to COMMON. The DZ-1011 Block Signal Detectors operate this way. The BLUE wire will HOLD the
gates down and cause the LEDs to flash. The YELLOW and WHITE wires will only TRIGGER the gates to go down and the
LEDs to flash, but after 6-8 seconds the gates will go up and the LEDS will stop flashing 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.
I would like block signal detectors to trigger and hold the gates down as long as the beam of light leaving the block signal detector is interrupted by an engine or rolling stock. Has anyone figured out a way for the detectors to trigger AND hold the gates down as long as its light is hitting a train?
thanks!
