The Omni eX® controller is a traffic management device designed for efficient and reliable control of intersections. It supports various cabinet types, including NEMA TS2 Type 1, NEMA TS2 Type 2, and ATC (SIU), offering flexibility for different infrastructure setups. The controller facilitates the management of traffic signals, pedestrian crossings, and other intersection components, aiming to optimize traffic flow and enhance safety.
The Omni eX controller serves as the central processing unit for an intersection, managing all aspects of traffic signal operation. Its core function is to execute timing plans and control signal indications based on real-time traffic conditions, pre-programmed schedules, and detector inputs. The device supports a standard 8-phase, 2-ring configuration, which is a common setup for managing traffic movements at intersections.
The controller's software allows for comprehensive programming of various operational parameters. This includes defining unit control operation modes, setting up startup sequences, configuring channel assignments, and mapping input/output (I/O) signals. It also handles logic gates, which are essential for implementing complex control strategies. Specific setups for NEMA TS2 and ATC/ITS environments are integrated, ensuring compatibility and optimal performance within these standards.
Phase timing and options are critical functions, allowing users to precisely control the duration of green, yellow, and red intervals for each traffic phase. This includes setting minimum and maximum green times, pedestrian clearance intervals, and detector recall options. The controller also manages overlaps, which are used to provide simultaneous green indications for certain movements, such as protected left turns or pedestrian crossings, without conflicting with other traffic flows.
Detector management is another key function. The Omni eX processes inputs from various types of vehicle and pedestrian detectors, using this information to dynamically adjust signal timing. This adaptive control helps reduce delays and improve efficiency by extending green times for active phases or skipping phases with no demand. Attributes for each detector, such as presence detection, pulse detection, and call types, can be configured.
For coordinated traffic systems, the controller supports coordination functions, including constants, patterns, and split tables. These features enable multiple intersections to operate in a synchronized manner, facilitating smooth traffic progression along a corridor. Time base functions allow for the creation of schedules, day plans, and actions, enabling the controller to automatically adjust its operation based on time of day, day of week, or special events.
The Omni eX also incorporates preemption capabilities, which are crucial for emergency vehicle priority or railroad preemption. It supports up to 8 preemption sequences, allowing for rapid and safe clearance of intersections when emergency vehicles approach or trains are present. Transit priority (TSP) functions are also available, offering global options, strategies, and timing parameters to give priority to public transit vehicles, further enhancing public transportation efficiency.
Logging functions are integrated to record operational data, events, and alarms. Users can view, clear, set up, and enable logs, which are invaluable for troubleshooting, performance analysis, and compliance reporting. The controller also provides network connectivity through IP addresses, supporting NTCIP and AB3418 protocols for remote monitoring, configuration, and data exchange with central traffic management systems.
The Omni eX controller is designed for ease of use, featuring a clear display and intuitive menu navigation. Upon initial power-up, the controller displays a Main Menu, which serves as the primary interface for configuration and monitoring. For FLeX and eX2 models, a 16-line display shows both Status and Main Menu screens, while the 2070 model uses an 8-line x 40-column LCD. Users can toggle between these screens using the "ESC" key.
Bench testing is a crucial usage feature, allowing technicians to configure and verify the controller's functionality before installation in a cabinet. During bench testing, specific serial communications for Terminal Facilities (TF), Detection (Det), and Monitors (CMU or MMU) may need to be disabled to prevent the controller from entering a stop time state, ensuring proper operation. The manual provides clear instructions for disabling these communications for NEMA TS2 Type 1, NEMA TS2 Type 2, and ATC (SIU) configurations.
Initializing the database is a fundamental step in setting up the controller. This process involves clearing the existing database and selecting the appropriate cabinet type and pedestrian/overlaps channel options. The system then requires confirmation before proceeding, ensuring that critical data is not accidentally erased.
Setting the system ID is an important usage feature, as it provides a unique 10-digit numeric identifier for each intersection. This ID is also used for naming locations when importing or exporting database files via the USB utility, streamlining data management.
The controller supports flexible network configuration, allowing users to input IP addresses, subnet masks, and gateways for both Port 1 and Port 2. Default values for NTCIP and AB3418 ports are provided, simplifying initial network setup.
Time zone and date/time settings are essential for accurate scheduling and logging. The controller allows users to set the local time offset from GMT, with predefined US time zones provided for convenience. The date and time can be precisely entered, ensuring that all time-based operations are correctly synchronized.
The customer support features include dedicated phone numbers for order status and technical services, ensuring that users can quickly get assistance when needed. The inclusion of a USB utility for importing/exporting database files further enhances usability by simplifying configuration backups and transfers.
The Omni eX controller is designed with maintenance in mind, starting with initial visual inspections. Before applying electrical power, users are instructed to visually inspect the controller's exterior for any shipping damage. This includes checking for loose or missing screws, shaking the unit to test for loose hardware, and ensuring the AC and +24VDC fuse holders are secure. These preventative checks help identify potential issues before they escalate.
The ability to clear the database is a powerful maintenance feature. If a controller needs to be reconfigured from scratch or if there are persistent software issues, initializing the database provides a clean slate. This process allows users to choose the cabinet type and pedestrian/overlaps channel options, ensuring the controller is set up correctly for its specific environment.
The logging functions are crucial for ongoing maintenance and troubleshooting. By viewing and analyzing logs, technicians can identify operational anomalies, diagnose faults, and track system performance over time. The ability to clear logs helps manage storage space and ensures that new data can be recorded efficiently.
The controller's modular design, supporting various cabinet types and communication interfaces, simplifies component replacement and upgrades. For instance, the ability to turn off specific SDLC communications during bench testing or troubleshooting helps isolate issues to particular modules or connections.
The comprehensive customer support system, including technical services, provides a direct channel for maintenance assistance. If issues cannot be resolved through on-site troubleshooting, expert support is available to guide users through complex diagnostics or provide solutions.
The use of standard communication protocols like NTCIP and AB3418 facilitates integration with central traffic management systems, which often include remote diagnostic and maintenance capabilities. This allows for proactive monitoring and remote resolution of certain issues, reducing the need for on-site visits.
Overall, the Omni eX controller is built for reliable, long-term operation with features that support both preventive and corrective maintenance, ensuring continuous and efficient traffic control.
