Explains the use of Datakey for electronic programming of the CMUip-2212.
Explains the CMUip-2212's response to fault conditions and entry into Failed State Action mode.
Describes the transition period and signaling when exiting the Failed State Action (FSA) state.
Details how the CMUip-2212 senses and monitors cabinet power supply sources (+48VDC, +24VDC, +12VDC).
Explains the detection of concurrently active signals on channel inputs for conflict determination.
Details the conditions that cause a FSA due to Serial Bus #1 communication errors.
Details the conditions that cause a FSA due to Serial Bus #3 communication errors.
Explains how Type 62 messages trigger NFSA or LFSA based on the 'N' or 'L' bit.
Describes the detection of absence of required signal voltage or output load current for a channel.
Explains the detection of active signals on two or more inputs of a channel.
Details the verification of the Yellow Change interval duration for signal sequences.
Verifies the Yellow Change plus Red Clearance interval between signal changes.
Monitors the LF STATUS input to indicate when the cabinet should be placed into NFSA.
Monitors the CB TRIP STATUS input for tripped circuit breakers.
Monitors voltage states of HDFU units for failed output alarms.
Monitors MAINS input and NRESET/POWERDOWN inputs for CMU Power Failure.
Monitors MAINS voltage and LV+/HV+ signals for dropout conditions.
Describes the disabling of +12VDC and +24VDC monitoring during power interrupt.
Continuous verification of field signal output states and their correspondence to ATC commands.
Compares field signals to ATC reported states, triggering LFSA on mismatch.
Compares field signals to CU reported states, indicating fault source.
Describes the CMUip-2212's self-check diagnostic capabilities and LFSA-R setting.
Verifies RAM elements operate correctly at power-up or after a Unit Reset.
Verifies nonvolatile flash ROM and event log eeprom contain proper data.
Verifies the non-volatile Datakey contains valid data and checks for version incompatibility.
Monitors the microprocessor operation and forces LFSA-R if logic state transitions are missed.
Detects intermittent or pulsing faults that normal algorithms may miss.
Monitors intersection approaches using the FYA movement as defined by NCHRP Research Project 3-54.
Defines nomenclature for FYA monitoring as described in NEMA Standard TS2-2016.
Explains automatic configuration of fault parameters for FYA using MonitorKey software.
Verifies no conflicting channels are active during Yellow arrow clearance sequences.
