      • Cycle timing
      • Phase split timing
      • Phase modes
  • Six Operational Modes can be selected for continual operation or can operate with a specific pattern
    • Permissive Mode provides non-actuated coord phase vehicle and pedestrian modes with permissive windows opened phase-by-phase to the non-coord phases.
    • Yield Mode provides non-actuated coord phase vehicle and pedestrian modes with a single permissive window for all non-coord phases.
    • Permissive Yield Mode provides for actuated coord phase vehicle and pedestrian modes with permissive windows opened phase-by-phase to the non-coord phases. Additionally, the coord phase vehicle can extend its green time at the beginning of the first permissive window.
    • Permissive Omit Mode provides operation similar to Permissive Yield except that the coord phase, once terminated, is prevented from occurring prior to the end of the last permissive.
    • Sequential Omit Mode provides operation similar to Permissive Yield except the permissive is a phase-by-phase sliding window (only one phase in a ring will be allowed service at any time).
    • Full Actuated Modes provides operation similar to Permissive Yield except that any phase can be serviced and re-serviced in the standard sequence following the first permissive and through the last permissive.
  • Four Correction Modes to determine the method in which the coordination will bring the background cycle in sync with the system cycle.
  • Three Maximum Modes to determine whether Maximum 1, Maximum 2, or Maximum Inhibit will be effective when coordination is in control.
  • Two Force Modes to determine whether the non-coord phase force will be based on a position in the background cycle or on the Timing Plan Phase Split Time.
  • Two Offset Modes to determine whether the Offset is calculated based on the Start or End of the first coord phase Green.
  • Local Traffic Responsive Override to enable selection of patterns based on computed volume plus occupancy of selected detectors.
  • Virtual Split Routine on all operational modes, which provides for actuated coord phase vehicle and pedestrian modes. This control provides for a period of time of each cycle, which is distributed to the Coord Phase(s) or non-coord phases, based on Coord Phase vehicle traffic activity.
  • Coordination activity can be monitored on a Coord Active Status display which denotes:
    • Operation, Correction, Maximum, and Force Mode
    • Cycle Time Parameter, Countdown, and Adjustment

  • Included are SIX Preempt routines providing complete signal control. Each routine provides the capability to program the state of the outputs for two Green Intervals. Outputs which are not normally on can be activated during preempt. The capability exists for limited cycling during the preempt dwell. The capability exists to link multiple routines to form more complex routines. Delay, Extend Duration, Max Call, and Lock Out timings exist for each routine.
  • Included are SIX Priority Routines providing complete phase control. Each routine provides the capability to program the phase(s) which are to be active in the dwell state. Delay, Extend Duration, Max Call, and Lock Out timings exist for each routine.
  • Preempt activity can be monitored on a Preempt Status display which denotes:
    • Preempt-In Control, Interval Timing, and Interval Countdown
    • Individual Preempt Status and Timing
    • Individual Priority Status and Timing

Reports - The EPAC300 Series Controller Unit provides an extensive report capability. Each report entry includes the Date and Time of occurrence.

  • Local Alarm Log with the capacity to store 120 events. Over 100 different events can be stored in this log.
  • Comm Fault Log with the capacity to store 60 events. Fourteen different communications type faults can be stored in this log.
  • Detector Fault Log with the capacity to store 60 events. Ten different detector diagnostic type events can be stored in this log.
  • System Detector Log with the capacity to store 96 events. Each event will note the raw volume, raw occupancy, average volume, and average occupancy on up to 8 detectors.
  • MOE Log with the capacity to store 24 events. Each event will note the Volume, Stops, Delay, and Green utilization on each phase for the active pattern.
  • Speed Log with the capacity to store 24 events. Each event will note the percentage for vehicles below, within, and above a user-defined speed for the active pattern.
  • Volume Count Log with the capacity to store 72 events. Each event will note the volume counts recorded by up to 24 detectors.

Diagnostics - A Resident Diagnostic Program is standard in the EPAC300 Series Controller Unit. In addition to the extensive displays to aid in intersection setup, monitoring, and operation, the resident diagnostic program enhances maintenance and troubleshooting. Many of the diagnostic routines execute automatically and continually, verifying unit integrity. Diagnostic analysis is displayed or logged in English.

  • Automatic Diagnostics begin at power up and continue as long as the unit is operating.
  • Power Up Diagnostics include PROM, RAM, EEPROM, Real-Time Clock, and Processor checks. Failures will result in the unit not enabling the Fault Monitor or Voltage Monitor outputs while the display shows messages such as "PROM TEST: FAILED".
  • Monitor Compatibility Programming Diagnostics include a verification that the Monitor Program Card Programming is consistent with Controller Unit Sequence.
  • Monitor Field Status Diagnostics include a redundant test for conflicting channels by being active simultaneously.
  • Cycling Diagnostics include a verification that phases with serviceable calls are receiving service in a timely manner.
  • Detector Diagnostics include a verification that detector activity is within thresholds defined by the user.
  • Port 1 Message Display - This status display will indicate the status of each bit in the requested message.
  • Port 2 Comm Status Display -This status display will indicate the port settings (i.e., 1200, 8N1), line status, carrier status, when transmitting, and when receiving.
  • Port 3 Comm Status Display - This display is a duplicate of the Port 3 display.
  • Hardware Input Status Display - This display will indicate the status of every hardware input (i.e., On/Off).
  • Hardware Output Status Display - This display will indicate the status of every hardware output (i.e., On/Off.)
  • Other features of the resident diagnostics program are available on user request, and when combined with an input/output monitor provide total indication of unit operation. For trend analysis, the failures are logged with date and time and remain available for display as needed.

TS 2 Advantages - Controller Assemblies that conform to NEMA TS 2-1992 Standard provide increased capability.

  • Controller Assemblies with TS 2 Detector Racks consume less power and provide additional diagnostic data to the Controller Unit via the SDLC port. The Controller Unit can take corrective action much earlier than it could, based on its own internal diagnostics.
  • Controller Assemblies with TS 2 Monitors provide additional diagnostic data to the Controller Unit via the SDLC port. The Controller Unit can take corrective action for improper Program Cards as well as Monitor failures.

Controller Types - The EPAC300 Series Controller Unit supports both NEMA TS 2 Type 1 and TS 2 Type 2 Actuated Controller Units.

  • The TS 2 Type 1 Actuated Controller Unit is a performance-oriented controller unit using a high speed data channel between all major components within the Terminal and Facilities as follows:
    1. Port 1 Connector -- a High Speed data channel connecting the controller unit, monitor, detectors, and back panel.
    2. Port 2 Connector -- a RS-232 (EIA/TIA Standard DTE Interface) in 25-pin configuration supporting baud rates from 1200 to 19200 bps. Used to interface with a Personal Computer, Printer, or a like controller unit.
    3. Port 3 Connector -- Used for On-Street Communications and available in the following forms:
      • 1200 Baud FSK Modem (2-wire or 4-wire)
      • Fiber Optic Modem with two ports supporting baud rates from 1200 to 19200 bps.
      • Two RS-232 (EIA/TIA Standard DTE Interface) in 9-pin and 25-pin configurations supporting baud rates from 1200 to 19200 bps.
  • The TS 2 Type 2 Actuated Controller Unit includes all the features of the Type 1 and adds the following:
    • MSA, MSB, and MSC connectors for data exchange with the Terminals and Facilities. This provides a degree of downward compatibility with NEMA TS 1 counterparts.
    • 37-pin "D" connector for backward compatibility with TS 1 counterpart.

Security - The EPAC300 Series Controller Unit offers a user specified security code entry before data can be altered. This security code entry is never required in order to view any parameter. The EPAC300 Series Controller Unit can disable security code requirements for perpetual access.

Hardware Design -

  • The EPAC300 Series Controller Unit is designed for efficient operation and ease of maintenance. The metal chassis has easy access to the boards for testing without disassembly. There are minimum components inside the EPAC300 for maximum reliability.
  • EEPROM technology is used to retain all timing and control parameters to insure the accuracy of traffic control parameters, even during power outages. No batteries are required for retention of traffic parameters. Event logging and the Time Base clock use RAM memory for those functions with battery support.

2070-NEMA - Features and Specifications

The initial effort to bridge the gap between CALTRANS and NEMA traffic control equipment was made by EAGLE when the MAGNUM card, with NEMA interface features, was introduced for placement in a CALTRANS Type 170 or Type 170E controller unit.

CALTRANS has now completed specifications for a controller unit to further efforts toward compatibility with NEMA. The basis of the controller unit is the power-enhanced and versatile Model 2070. For NEMA compatibility, the Model 2070 unit allows the attachment of a lower section which contains the NEMA TS1 "A," "B," and "C" connectors, a "D" connector, and an RS232 communications port.

The addition of the lower NEMA compatible section to the Model 2070 and the replacement of the 2070-2 module with a 2070-2A module creates the CALTRANS specified Model 2070N controller unit, which is specifically designed to function in a NEMA TS1 cabinet.

The Model 2070N allows NEMA equipment users to capitalize upon the Model 2070's open VME bus architecture features. For instance, the control of a variable message sign can be added by a module installation.
