Main applications
- Traffic regulation and safety in multi-storey and underground car parks: optimized management of ramps and alternating one-way systems
- Industrial safety and logistics: flow control of heavy vehicles in loading/unloading areas and industrial driveways
- Residential access automation: management of apartment building gates with facilitated exits via sensors or timers
- Optical signaling device for construction sites and passages: timed or priority regulation for narrow passages and private roads
Target clients
- Industrial installers: for the simplicity of wiring and the robustness of the DIN rail system
- System integrators: who require a versatile interface with auxiliary outputs (AUX) for complex logic
- Automation maintenance technicians: thanks to real-time diagnostics provided by the integrated display

Product dimensions
Operating logics
- PRIORITY (Reservation): the green light cycle is activated by command devices such as sensors or buttons connected to Input 1 and 2. This is the optimal mode for managing variable traffic flows safely
- TIME-BASED (Timing): cyclical operation based exclusively on the preset times (TV1, TV2, and TSG). It does not require external sensors
- STATE-BASED (State): the traffic light switches to green and remains green for the entire duration of the physical activation of the input, regardless of any timers
- TESTING: A mode reserved exclusively for internal product testing by the manufacturer's personnel
Timing parameters
Installer notes
- Simplified wiring: the common pole of the two traffic light terminal blocks is electrically connected via an internal track; therefore, it is sufficient to connect the common wire to only one of the two blocks
- Diagnostics: by pressing and holding the ESC button for 3 seconds, the firmware version and serial number can be viewed on the display
- Safety: in the event of an alarm (Input 3), the unit can be configured to trigger a "flashing red" state
Case study
Caso Studio: Senso Unico Alternato
Scenario tipico di gestione del traffico in ingresso e uscita da un parcheggio condominiale, mediante logica di senso unico alternato.
Stato di Standby
Il semaforo sulla strada principale è verde di default — il traffico pubblico scorre senza interruzioni. Il semaforo del parcheggio è rosso, impedendo uscite non controllate.
Veicolo Rilevato
Quando il sensore rileva un veicolo in uscita dal parcheggio, il sistema attiva automaticamente la sequenza temporizzata di gestione del traffico — consentendo l'uscita in sicurezza senza intervento manuale.
Traffic Light Configuration
The system uses two traffic lights managed by a single VIACONTROL unit in Reservation (priority) mode.
Main Road
Set to green by default (F3 = V1 R2). Does not interrupt public traffic unless a vehicle requests exit from the parking.
Parking Entrance/Exit
Red by default. Switches to green when the detection sensor at the parking exit is triggered. Connected to Input 1 or Input 2.
Operation Sequence
The Reservation operating mode activates only when a vehicle is detected — minimising disruption to public road traffic.
Standby
Main road: GREEN — Parking exit: RED. The system is idle, awaiting a trigger from the detection sensor.
Area Clearance (TSG)
Both traffic lights switch to RED. The TSG timer runs, ensuring the transit area is fully clear before any green is granted.
Green Phase (TV1/TV2)
The parking exit light turns GREEN for the configured time, allowing the vehicle to exit safely. The main road light is RED, blocking incoming traffic.
Second Area Clearance (TSG)
Both lights return to RED for a second TSG cycle — ensuring the exiting vehicle has fully cleared the transit area before restoring normal flow.
Return to Standby
The system automatically returns to standby: main road GREEN, parking exit RED. Ready for the next vehicle detection.

| TAUX2 AUX2 output time | 10 s | — |
System Advantages
Why the Reservation mode is the optimal choice for asymmetric traffic scenarios like parking access control.
Minimal impact on public traffic
Unlike Time mode, Reservation only activates when a vehicle is actually present — the main road light stays green indefinitely when the parking is idle.
Double safety clearance
The TSG timer fires twice per cycle — before and after the green phase — providing two independent safety windows to ensure the transit zone is clear.
Simplified wiring — single sensor
Setting F3 = V1 R2 or R1 V2 allows a single detection device to control the entire cycle, connected to the input of the resting red light only.
Fully automated — no manual intervention
Once configured and commissioned, the system manages the entire traffic sequence autonomously. The installer simply calibrates the timings to match the physical site dimensions.
