ASC/3 Series NEMA TS2/NTCIP Actuated Controllers
The ASC/3 combines the requirements of NEMA TS2 and NTCIP, along with new hardware and the familiar software features of the ASC/2, allowing a lower cost of ownership and expanded adaptability for developing traffic strategies.
Description
The ASC/3 is the latest in a series of Advanced System Controllers offered by Econolite. It builds on the proven software, design flexibility, and unique feature set of the popular ASC/2 family of controllers.
The ASC/3 has been developed to fully comply with all NEMA TS2 and NTCIP requirements. In addition the design, manufacturing and testing of the ASC/3 have used processes controlled by the latest ISO quality standards.
The ASC/3 provides an updated hardware design that allows it to serve as the traffic control platform for the present and future traffic management environments. This includes NEMA TS2 and NTCIP compliance and compatibility with all existing Econolite systems.
The ASC/3 is designed using the latest electronic technology. This offers the end user a controller that is more reliable, easier to maintain, and interchangeable with TS1 and TS2 controllers while continuing to offer a competitive price.
The majority of the electronic components of the ASC/3 are contained on one easy- to-replace module.
All firmware in the ASC/3 is stored in flash memory. This allows for quick and easy software updates in the field with-out changing hardware.
The ASC/3 firmware is easily updated in the background while the intersection remains in operation. Once updated, the controller only needs to be power cycled for a short amount of time to allow the new firmware to take control.
The ASC/3 uses the largest LCD display module (16 lines x 40 characters) in the industry to simplify the user interface. This display provides improved viewing in all lighting conditions. In addition, an optional display heater is available that enhances the display performance in temperatures below 0° F (-18° C).
Controller Models
The ASC/3 is available in two models. Both share a common enclosure, power supply, processor, keyboard, display and optional data, telemetry and Ethernet modules.
• ASC/3-1000: Dedicated to the TS2 Type 1 environment.
• ASC/3-2100: Can operate in any TS1, TS2 Type 1 and TS2 Type 2 environment.
FEATURES
• Exceeds NEMA TS2 and NTCIP requirements.
• State-of-the-art manufacturing and design for reliability, maintainability and cost effectiveness.
• Designed, manufactured and tested in an ISO certified environment.
• Windows based remote user interface (optional).
• Advanced controller, coordinator and preemptor features.
• Optional Data Key.
• Optional Ethernet support for 10/100 Base T networks.
• 16 x 40 LCD display with adjustable contrast.
• Enhanced transient and environ-mental protection.
• Protocol support for ECPIP, NTCIP, AB3418, Aries® and icons®.
ASC/3-1000: NEMA TS2 Type 1
The ASC/3-1000 meets and exceeds all the requirements of the NEMA TS2 Type 1 Standard. Its interface controls all inputs and outputs over a high-speed RS-485 serial bus (Port 1) with digital addressing that simplifies cabinet wiring. This bus also interfaces directly to a TS2 Malfunction Management Unit (MMU) for enhanced intersection monitoring.
ASC/3-2100: NEMA TS2 Type 2 / TS1
The ASC/3-2100 meets and exceeds all the requirements of the NEMA TS2 Type 2 Standard. It also provides downward compatibility to the Econolite KMC-8000, ASC-8000, ASC/2-2100 and ASC/2S-2100 controllers and other NEMA TS1 controllers. This adds an expansion to the customers inventory, not a replacement of it.
An optional 25-pin telemetry connector matches the KMC-8000 and ASC-8000. This allows the ASC/3-2100 to be used as a direct replacement for these older controllers.
