Installation and Commissioning Guidelines for KTI 300 mm Cross / Arrow Signal

Mechanical Mounting and Overhead Structural Integration

The KTI KTI16022900CR30 300 mm traffic signal is engineered with a compact single-aspect footprint measuring 310 mm x 310 mm x 100 mm. Its unified design houses both the Red Cross and Green Arrow in one 300 mm diameter display aperture, significantly reducing the structural load and clearance profile compared to multi-head signal stacks. Weighing less than 2 kg, the unit minimizes mechanical stress on supporting infrastructure, enabling straightforward installation on toll canopy fascias, overhead gantries, cantilever arms, wall brackets, and vertical or horizontal pole mounts across roadway checkpoints, parking facilities, and weighbridge lanes.

The housing and front lens are constructed from UV-stabilized polycarbonate designed to withstand extreme outdoor conditions. When positioning the signal, ensure the 300 mm optical face is aligned directly with the approaching vehicle driver sightline to maximize the visibility of the 400 cd Red Cross and 400 cd Green Arrow optical outputs. Mounting hardware should firmly anchor the 310 mm x 310 mm enclosure to structural supports to prevent vibration-induced misalignment in high-wind or heavy-traffic environments.

Electrical Wiring and Power Supply Requirements

The KTI16022900CR30 operates across dual standard DC operating voltages, supporting both 12V DC and 24V DC infrastructure. This compatibility allows direct connection to low-voltage industrial DC power distribution buses, uninterruptible power supplies (UPS), or dedicated automation control panels commonly deployed at toll plazas and industrial gate facilities.

With a low power consumption profile between 11 W and 12 W, the signal ensures minimal thermal build-up inside the sealed polycarbonate enclosure and reduces power draw on centralized supply systems. Field technicians should verify voltage polarity and line regulation at the junction terminal before applying power to protect the 625 nm (Red) and 500 nm (Green) LED arrays.

Control Interfacing and Automation Integration

Designed for automated lane control and overhead lane signalling (OHLS) systems, the signal interfaces seamlessly with external control logic:

• Toll Lane Controllers: Connect directly to toll management system (TMS) switching circuits to display lane open (Green Arrow) and lane closed (Red Cross) states.
• PLC and Relay Outputs: Integrate with industrial programmable logic controllers (PLCs), barrier gate controllers, and weighbridge management software via dry contact relays or solid-state switching channels.
• Access Control & Parking Systems: Coordinate signal states with automated boom barriers, vehicle detection loops, and automated payment stations to control traffic sequencing.

Ingress Protection and Environmental Sealing

The unit features an IP65 ingress protection rating, making it completely dust-tight and resistant to low-pressure water jets from any direction. During installation, ensure cable entry glands are securely tightened against the UV-stabilized polycarbonate body to preserve the IP65 environmental seal against moisture, dust ingress, and driving rain.
