and allow normal operation of the intersection. With this feature, the start up flash time will be less than one
second.
2.6.3.3
LOW AC POWER THRESHOLDS
Configuration:
This is a factory option and cannot be changed by the user. If this function is required but it is not
active, contact Reno A&E Technical Support for assistance. This feature is set to OFF for all units unless
specifically requested to be turned on when ordered.
Operations Modified:
Monitor Power Up / Power Recovery
: When Low AC Power Thresholds is enabled, the valid AC
voltage threshold is changed from 103V
RMS
to 98V
RMS
.
Monitor Power Failure
: When Low AC Power Thresholds is enabled, the invalid AC voltage
threshold is changed from 98V
RMS
to 92V
RMS
.
Typical Use
: Some agencies prefer the lower AC power thresholds especially in areas with chronic low voltage
issues.
2.6.3.4
DIAGNOSTIC LCD
Configuration:
This is a factory option and cannot be changed by the user. If this function is required but it is not
active, contact Reno A&E Technical Support for assistance. This feature is set to OFF for all units.
Operations Modified:
Diagnostic LCD
: The monitor is capable of driving a special 4 line by 40 character diagnostic display.
This display can display any of over 40 diagnostic screens. The active screen is selected using Option
Switches 3 through 8. When this feature is enabled, any changes to these six Option Switches will not
cause configuration changes, only change the active diagnostic screen. The state of the Option
Switches prior to the activation of this feature will be used until this feature is turned off.
Typical Use
: Troubleshooting of monitor issues by factory personnel.

SOFTWARE OPTIONS
2.6.4.1
LOG FIELD CHANGES
Configuration:
This is a feature that can only be modified through the use of the RaeComM software and a
computer or laptop. In the RaeComM software click on the wrench icon or on the menu choose Config / Monitor
Configuration. This feature is on the Electronic Options tab and in the Software Option box in the lower right.
This feature is set to OFF at the factory.
Operations Modified:
Signal Sequence Log
: When Log Field Changes is enabled, the Signal Sequence log will change from
recording the state and voltage on every input every 33 milliseconds to checking every 33
milliseconds to see if the state of any input changed. The Watchdog input will not be included in the
inputs checked for state changes. If there were no state changes, length of the current log entry is
increased by 33 milliseconds and no new log entry is made. If there were state changes, a new log
entry is made and the voltages are recorded at this point.
Typical Use
: Since the Signal Sequence log has 60 entries, at 33 milliseconds per entry, the log can only record the
events for two seconds prior to the fault. With this feature, the monitor can record the 60 state changes prior to the
fault. How far back in time this will record will depend on how often inputs are changing states. A typical
intersection with pedestrian movements will record about 40 seconds.
2.6.4.2
FYA FOR CHANNELS 1-4 USE YELLOW DRIVERS (FYA 1-4 USES YEL)
Configuration:
This feature is only effective if Flashing Yellow Arrow Enable (Option Switch 2 – FYA EN) is
active. If any of channels 1 through 4 will be a parent (the protected display) channel for a Flashing Yellow Arrow
head, this feature is used to select which driver from the permissive child channel will be used to make up the four
sections of the Flashing Yellow Arrow head. ON (checked) indicates that the Yellow of the child channel will be
used. OFF (unchecked) indicates that the Green of the child channel will be used. This feature can only be
modified through the use of the RaeComM software and a computer or laptop. In the RaeComM software click on
the wrench icon or on the menu choose Config / Monitor Configuration. This feature is on the Electronic Options
tab and in the Software Option box in the lower right. This feature is set to OFF at the factory.
Operations Modified:
Conflict Monitoring
: When Flashing Yellow Arrow Enable and FYA for Channels 1-4 Use Yellow
Drivers are both enabled, the Yellow of the permissive child channel will conflict with the conflicting
child channel if the flashing yellow arrow does not flash. When Flashing Yellow Arrow Enable is
enabled and FYA for Channels 1-4 Use Yellow Drivers is disabled, the Green of the permissive child
channel will conflict with the conflicting child channel if the flashing yellow arrow does not flash.
