Typical Use
: In Type 12 mode of operation, this feature allows vehicle displays to be checked for a dark head even though a
walk for the channel may be active. In Type 16 mode of operation, this feature allows for a longer Yellow + Red dual
indication fault time to deal with some controllers that have a slight overlap between the pedestrian clearance interval and the
don’t walk interval of a pedestrian channel.

EVENT LOGGING
Six different Event Logs provide detailed, date and time stamped documentation of selected events recorded by the monitor.
This data is useful in troubleshooting and provides an accurate historical record of cabinet operation. When the date and time
are not available through Port 1, the monitor will use its internal Real Time Clock as a date / time stamp for events.
2.7.1 Time Change Log
The Time Change Log records the 50 most recent time changes. Data recorded: Original Date / Time Stamp, New Date /
Time Stamp, and Up Time Accumulator.
2.7.2 Monitor Reset Log
The monitor Reset Log records the 20 most recent resets. Data recorded: Date / Time Stamp, Faults at Time of Reset, and
Source of Reset (Front Panel, External, or Power Loss).
2.7.3 Configuration Event Log
The Configuration Event Log records the 10 most recent configuration changes. Data recorded: Date / Time Stamp,
Programming Card Jumpers, Type Select, Factory Options set through RaeComM, and User Options set through RaeComM.
2.7.4 Prior Faults Log
The Prior Faults Log records the 20 most recent faults. Data recorded: Date / Time Stamp; Cabinet Temperature; Faults
Reported; Status of all Greens, Yellows, Reds, and Walks; Status of all DC Inputs; Status of Red Enable; Entire Front Panel
Fault Display; AC Line Voltage; and Red Enable Voltage.
2.7.5 AC Line Log
The AC Line Log records the 50 most recent changes in AC line status. Data recorded: Date / Time Stamp, Event Type
(Power Up / Reset, Low Voltage, Low Voltage Recovery, Shutdown, Low Voltage Alarm, Low Voltage Alarm Recovery,
High Voltage Alarm, and High Voltage Alarm Recovery), and AC Line Voltage.
Through RaeComM, the user can adjust the High Voltage Alarm point and the Low Voltage Alarm point. These alarm points
have a fixed, three volt hysteresis. Therefore, setting the High Voltage Alarm point to 135 volts will cause the recovery point
to be set to 132 volts. Likewise, setting the Low Voltage Alarm point to 105 volts will cause the recovery point to be 108
volts. The factory defaults for these alarm points are 105 volts for the low alarm point and 135 volts for the high alarm point.
NOTE: The log will only record when these points are crossed. The minimum and maximum voltages seen are not recorded.
2.7.6 Signal Sequence Log (Logs last 13 failures)
The Signal Sequence Log can be configured to record events occurring prior to a fault in one of two different modes.
Event Mode
: The Signal Sequence Log records the 60 most recent events preceding the failure. An event is defined as an
instance when any AC or DC signal changes state. The monitor checks all inputs for changes in state every 33 milliseconds
for the purpose of accumulating data for this log. Data recorded: Time Prior to Fault; Status of all Greens, Yellows, Reds,
and Walks; RMS Voltages of all Greens, Yellows, Reds, and Walks; Status of all DC inputs; Status of Red Enable; AC
Line Voltage; Red Enable Voltage; and DC Input Voltages.
Time Mode
: The Signal Sequence Log records the 2 seconds preceding the failure. The monitor records all inputs every 33
milliseconds for the purpose of accumulating data for this log. Data recorded: Time Prior to Fault; Status of all Greens,
Yellows, Reds, and Walks; RMS Voltages of all Greens, Yellows, Reds, and Walks; Status of all DC inputs; Status of Red
Enable; AC Line Voltage; Red Enable Voltage; and DC Input Voltages.
