  • Page 5: Section 1 General

    Auxiliary Monitor Unit (AMU) located in each Output Assembly via Serial Bus #3. The role of the CMU-212 is to query various cabinet conditions and, if the application requires action, the CMU-212 will transfer control from the Advanced Traffic Controller (ATC) to a flashing control mode.

  • Page 6: Cmu-212 Programming

    Datakey replaces the mechanical jumper or diode based program card used in conventional signal monitors and provides an electronic method of programming the CMU- 212. The Datakey contains a nonvolatile prom device that is read by the CMU-212. The Datakey itself is programmed by a separate programming device using a Personal Computer program such as the Eberle Design MonitorKey product.

  • Page 7: Serial Bus #1

    Messages are defined that allow the ATC and the CMU-212 to perform redundant checks on each other. The ATC has access to all CMU-212 information including field signal input status, permissive programming, and fault status. This gives the ATC the capability to provide a backup monitoring function and make enhanced event logging, remote intersection monitoring, and remote diagnostics feasible.

  • Page 8: Exit From Fsa

    Fault state, a transition period of 500 milliseconds will occur. During the transition period the OUTPUT NO contacts will be in the FSA state and the CMU-212 will set the Start-Up Flash Call bit in the Type 189 Frame to 1. At all other times the Start-Up Flash Call bit of the Type 189 Frame will be set to 0.

  • Page 9: Section 2 Monitor Functions

    ATC for greater than 1000 milliseconds. The first and second failures in a 24-hour period will be a NFSA. The third failure in a 24-hour period will be a LFSA-R. If a CMU-212 Power Fail resets the LFSA-R, the SB #1 failure count will be reset to two, such that the next SB #1 timeout results in a LFSA-R.

  • Page 10: Type 62 Fsa Message

    2.4 TYPE 62 FSA MESSAGE If the “N” bit is set in a Type 62 message, the CMU-212 will react by causing a NFSA. The NFSA will remain until the receipt of a Message 62 with the “N” bit cleared or until the CMU-212 is reset by a Unit Reset or CMU-212 Power Fail.

  • Page 11: Yellow Plus Red Clearance Monitor

    Yellow Change plus Red Clearance interval monitoring on a per channel basis. 2.9 LOCAL FLASH STATUS The CMU-212 will monitor the LF STATUS input. This input is used to indicate to the CMU- 212 that the cabinet should be placed into NFSA as a result of the AUTO/FLASH switch being transferred to the FLASH postion.

  • Page 12: Ac+ Raw Level Sense

    AMU-214. When any AC+ RAW voltage is less than the AC Line Dropout voltage (section 5.1) for greater than AC Line Level Sense timing (section 5.2) the CMU-212 will cause a NFSA. Once NFSA has been set, the POWERDOWN and NRESET signals will not be monitored until all AC+ RAW voltages have exceeded the AC Line Restore voltage (section 5.1).

  • Page 13: Field Check Status

    CMU-212 will not cause a LFSA. When a mismatch is detected for 1000 milliseconds or more, the CMU-212 will cause a LFSA. When a mismatch is detected for more than 700 milliseconds but less than 1000 milliseconds, the CMU-212 may or may not cause a LFSA.

  • Page 14: Internal Mpu Monitor

    FRONT input is sensed as active (door open). 2.14.4 INTERNAL MPU MONITOR The CMU-212 will monitor the operation of its microprocessor with an independent circuit. At a minimum, the monitoring circuit will receive logic state transitions at least once every 50 milliseconds from the microprocessor.

  • Page 15: Flashing Yellow Arrow (Fya) Protected-Permissive Monitoring

    Operations Manual 2.16 FLASHING YELLOW ARROW (FYA) PROTECTED-PERMISSIVE MONITORING The CMU-212 is designed to monitor an intersection with up to six approaches using the four section Flashing Yellow Arrow (FYA) movement outlined by the NCHRP Research Project 3-54 on Protected/Permissive signal displays with Flashing Yellow Arrows, and complies with all requirements of NEMA Standard TS-2 Amendment 4-2012 Flashing Yellow Arrow.

  • Page 16: Conflict

    INPUT Enable option is Enabled for that channel. 2.16.2.1 CONFLICT The CMU-212 will verify that no conflicting channels to the solid Yellow arrow channel (clearance) are active as determined by the Program Card compatibility programming of the solid Yellow arrow channel of the pair except during the following sequences: 2.16.2.1.1 PROTECTED YELLOW CHANGE INTERVAL CONFLICT...

  • Page 17: Dual Indication

    In these cases the Red and Yellow inputs for the sparse FYA channels can be forced to the Off state in the CMU-212 by default. This simplifies the cabinet wiring such that the use of dummy cabinet loads or modifications to the Output harness are not necessary.

  • Page 18: Fya Yellow Trap Conflict Detection

    When the FYA Yellow Trap Conflict condition is detected, the CMU-212 will enter the fault mode, transfer the OUTPUT relay contacts to the Fault position, and display the “CONFtrap” fault status screen. The CMU-212 will remain in the fault mode until the unit is reset by the RESET button.

  • Page 19: Section 3 Input Signals

    89 Vrms. This input will not be considered active when the input voltage is less than 70 Vrms. Signals between 89 Vrms and 70 Vrms may or may not be considered active. The CMU-212 will report the state of this input in the Type 189 frame.

  • Page 20: Ftr Coil Drive Status

    CMU-212 Cabinet Monitor Unit Operations Manual may not be considered active. The CMU-212 will report the state of this input in the Type 189 frame. 3.3.4 FTR COIL DRIVE STATUS The cabinet should be wired such that the FTR COIL DRIVE STATUS input is connected to the FTR COIL DRIVE signal in the AC SIGNAL POWER BUS.

  • Page 21: Serial Bus #1 Disable Input

    VDC GROUND (True) The CMU-212 will not communicate on Serial Bus #1 or set a FSA condition if communications from the ATC is not present. See section 2.3.1. The SERIAL BUS #1 DISABLE input is intended for use in testing the CMU-212 and should not be connected in the cabinet.

  • Page 22: Section 4 Front Panel Description

    2.12. 4.1.2 24VDC FAIL INDICATOR A red 24VDC FAIL indicator will illuminate when the CMU-212 is in FSA as a result of a 24VDC cabinet power supply fault. The 24VDC FAIL indicator will pulse at a 2 Hz rate when the 24VDC monitor function is disabled.

  • Page 23: Sb #1 Error Indicator

    4.1.10 SB #1 ERROR INDICATOR A red SB #1 ERROR indicator will illuminate when the CMU-212 is in FSA as a result of a Serial Bus #1 fault. See section 2.3.1. The SB #1 ERROR indicator will pulse at a 2 Hz rate when the SERIAL BUS #1 DISABLE input is True.
