either timer control or
signal / impulse control
The traffic light controller CTL1
alternatively activates two lights (red and green), usually in car parks, housing developments and everywhere where two-way traffic needs to be controlled.
Timer control:
Duration of the two light phases is governed by two adjustable resistors. In this instance no sensors (optical or electrical) are used.
Signal/impulse control (i.e. optical or electrical sensors):
Duration of the two light phases is governed by optical, electrical oder other sensors.
