DESCRIPTION OF THE PRODUCT
The electronic control unit is used to co-ordinate the two-light traffic lights in car parks, residences and wherever orderly access management
is needed (for example, along a single lane with alternating traffic, or at a simple junction). This control unit has two possible operating logics:
1. time operating logic. The red and green times that will be connected to the control unit are set by adjusting the respective trimmers. This
logic does not use photocells or other sensor devices since the system is controlled solely by the times set for the two traffic lights.
2. operating logic with sensor devices (for example, photocells). The red and green times that will be connected to the control unit are de-
termined by the signals from the photocells or from other sensor devices. Subsequently the operating logics will be explained in greater
detail along with the directions on how to set the two different modes.
MAIN TECHNICAL SPECIFICATIONS
Power supply 230 V, 50 Hz, 5 VA. 1 auxiliary output voltage 24 Vac, 130 mA max (for photocells, magnetic coils, etc.)
1 fuse to protect the line 160 mA.
1 fuse to protect the auxiliary output 160 mA
4 relay outputs with clean contact on switchover (230 V, 2 A max).
2 N.O. or N.C. settable control device inputs (photocells, etc.) 1 microswitch (Dip 2) to select N.O. or N.C. inputs.
1 microswitch (Dip 1) to select operation with sensor device or by time.
1 trimmer (T1) to adjust red light time (range from 5 to 120 seconds).
1 trimmer (T2) to adjust green light time (range from 5 to 120 seconds).
1 trimmer (T3) to adjust priority time (range from 5 to 120 seconds).
5 LEDs to signal input and output statuses. Here we show the wiring diagram for the main components of the electronic control unit.
The electronic control unit has two microswitches (Dip) that enable selecting the operating mode of the control unit and the type of contact
for the input control devices. Here we show the possible combinations:
