6.1 Traffic light function with STA 11
Traffic light control unit STA 11
Function
At the terminals of the traffic light controller separate impulse generators can be connected for „inside“ and „outside“.
The programming of the traffic light control is done in the progrmming menu of the connected operator control board.
These relate to the function of the duration of the green phase and the clearance time, the traffic light at the door position
„closed“ (whether or continuous red) and the traffic light system logic.
Depending on how the „traffic light logic“ was adjusted, after completion of command processing and gate opening, either the
side, which has given the order, or both sides receive the green light. Vehicles can therefore only drive in one direction or both
directions entering the gate area. Furthermore, the traffic light controller has the capacity to store incoming transit needs and
to work at the end of the current cycle.

•
if during the closing procedure an impulse is generated, so the gate opens
immediately, and the green phase begins when the opening is completed.
•
If a further order from one side is given with traffic light logic „both sides Green“ during the green phase/clea
-
rance time is given, then the green phase is restarted.
•
If a further order from the same side
is given with traffic light logic „one side Green“ during the green phase/
clearance time, then a restart of the green phase
for this side is effected.
•
If a further order from the counter side
is given with traffic light logic „one side Green“during the green phase/
clearance time, then the barrier remains after the green phase/clearance time open and the Green display
changes to the counter side.
When the stop button is triggered, the gate stops moving and only opens again with command by either side.
