Short description
The circuit enables the automatic operation of a light barrier and a
lifting barrier on two tracks independent of each other. The track is
passable from both directions; the module gives a "free" signal
only when both tracks are released.
As the vehicle passes the sensors (e.g. TM-73379: Reflective
object sensor) it activates the red blinking signal. Thereafter also
the barrier closes with a delay. As soon as the last carriage has
passed the given sensor, the barrier will be released; the light
signal will be turned off with a delay.
No direction distinction is required at the sensors along the given
track section! Each sensor will automatically obtain a locking or
release function.
Inputs
The module supply voltage is to be connected to the POWER
input.
