2.4.7  Temperature Sensor 

The monitor is capable of monitoring the temperature inside of the cabinet.  The temperature sensor is capable of monitoring 
temperatures in the range of -40

 F to +214

 F (-40

 C to +101

 C).  The internal cabinet temperature is included in the data 

logged into the Prior Faults Log when a fault occurs.  If the actual temperature inside the cabinet is below -40

 F (-40

 C) at 

the time the fault occurs, the temperature is logged as -40

 F (-40

 C).  If the actual temperature inside the cabinet is above 

+214

 F (+101

 C) at the time the fault occurs, the temperature is logged as +214

 F (+101

 C). 

2.4.8  Real Time Clock 

The monitor has a Real Time Clock (RTC) that is used as a reference for all date and time stamped events that are logged by 
the monitor.  The Real Time Clock is initialized to local Pacific Standard Time when the unit is undergoing final test.  In 
addition, the Daylight Saving Time user option is set to Off. 

The Real Time Clock is preprogrammed to recognize Leap Years and Daylight Saving Time events through the year 2099.  
Currently, per U.S. Federal standards, Daylight Saving Time is observed in the United States from 2:00 A.M. on the second 
Sunday in March until 2:00 A.M. on the first Sunday in November. 

The update priority of any time setting that affects the Real Time Clock is as follows: 

1.  Controller  Time  -  The  Real  Time  Clock  is  programmed  with  the  time  setting  received  from  the  Controller.    This 

information is received via the PORT 1 SDLC connector on the front of the monitor.  If the Real Time Clock setting 
differs from the Controller Time setting by more than two (2) seconds, The Real Time Clock will be synchronized to 
the Controller clock.  In the event that the Real Time Clock setting differs from the Controller Time setting by five (5) 
or more seconds, the Real Time Clock will be synchronized to the Controller clock and an entry will be made to the 
Time Change Log. 

2.  External Time  Source (i.e. laptop computer)  - The  Real Time  Clock setting can  be  modified through the  use of the 

RaeComM software.  Connection to the laptop computer is made via the COMM PORT serial connector or optional 
Ethernet connector on the front of the monitor.  NOTE:  Whenever the monitor is connected to an operational SDLC 
bus, any time setting entered via the serial port will be overwritten by the Controller Time setting. 

3.  Front Panel - The Real Time Clock setting can be modified through the front panel.  NOTE:  Whenever the monitor is 

connected  to  an  operational  SDLC  bus,  any  time  setting  entered  via  the  front  panel  will  be  overwritten  by  the 
Controller Time setting. 

If it is necessary to change the Real Time Clock setting in a monitor that is being used in a NEMA TS 2 Cabinet Assembly, 
change the time setting on the cabinet controller.  The time change will be broadcast to the monitor through the SDLC port. 

2.4.9  Up Time Accumulator 

The monitor has an Up Time Accumulator that keeps track of the total amount of time that the monitor has been powered up 
since  it  was  manufactured.  It is  saved in the  format of Years, Months, Days, Hours,  Minutes, and Seconds.   The MMU-
1600G warranty coverage is valid for a total accumulated Monitor Up Time of two (2) years.  Tracking and recording the 
total time that the unit was in service provides an accurate means of validating any potential warranty claims. 

2.4.10  Configuration Monitoring (Beeping Monitor) 

The monitor checks all configuration settings for changes once each second.  If a change is found, an audible buzzer will start 
beeping to indicate that a configuration setting has changed except when the monitor is in one of the configuration screens.  
This is to  keep the buzzer from being too annoying  when you know  you are  making changes.  However,  if  you leave the 
configuration  menu  the  monitor  will  start  beeping.    If  the  change  is  undone,  the  beeping  will  stop.    No  fault  monitoring 
configuration changes are implemented until the front panel reset pushbutton is pressed and held for five (5) seconds or the 
changes are saved using the Fault Configuration Menu.  At that time five quick confirmation beeps will be heard, the new 
settings will be implemented, and a Configuration Change log entry made.   

The following configuration settings are monitored: Programming Card jumpers, Type Select input, Factory Options, Dual 
Indication / Field Check, Per Channel Red Enables, Flashing Don’t Walk Monitoring, Flashing Yellow  Arrow Left Turns, 
Co-Channels, Thresholds, Logging Enables, Disable Local Flash, Modified CVM Latch, External Watchdog Enable, Type 16 
Only, and Buzzer Disable. 

On  power  up  and  any  time  the  program  card  is  changed  the  configuration  stored  on  the  program  card  is  compared  to  the 
configuration  stored  in  the  monitor.    If  they  do  not  match  the  user  is  prompted  to  choose  which  data  set  to  use.    If  the 
program card is selected, the configuration settings on the card will be copied into the monitor.  If the monitor is selected, the 
configuration  settings  on  the  program  card  are  overwritten  with  the  current  monitor  configuration.    All  user  information 
(Ethernet settings, Location, Location ID, and Agency ID) as well as fault monitoring settings are copied.  See Section 

4.10 

for front panel display during selection of configuration source.
