S600+ Instruction Manual 
7-2  Startup  Revised July-2017 
7.3  Cold Start 
During a cold start, the S600+ copies the configuration file from flash 
memory and replaces any online changes that have been made to the 
configuration files either since the last ones downloaded from a PC 
running Config600 software or since the last backup. During a cold 
start, you have the option of keeping or resetting the cumulative totals. 
You can only keep totals if the structure of the database has not been 
changed.  
Use a cold start after you send a new configuration to the S600+ or to 
recover from extreme situations, such as a corrupted database. A cold 
start builds a new metering database, using the configuration data 
stored in the S600+’s flash memory.  
Note:  You must perform a cold start if you update or otherwise 
change the firmware.  
7.3.1  Initiating a Cold Start 
You initiate a cold start using either of two methods:  
  Unpowered.  
  Powered with operating S600+. 
If the S600+ is not powered up, you may set bit link P2 on the CPU 
module to the closed (cold start) position and then apply power to the 
S600+. This displays the Startup menu.  
Exercise caution if you set the jumper. When you set the cold start 
jumper, remember that the S600+ also uses this setting if it self-starts 
for any reason, such as a low-voltage shutdown or recovery from a 
malfunction. Remove the cold start jumper setting when you do not 
need it. Otherwise, an unplanned restart could result in lost data. 
 
1.  Select COLD START from the Startup menu (see Figure 7-1).  
2.  Press 1 (to keep) or 2 (to reset) the totals.  
3.  Press 1 to confirm the selection. The S600+ displays the message 
CONFIGURING – PLEASE WAIT.   
The S600+ builds a new database using the configuration files held 
in flash memory. When completed, the S600+ Main menu displays.  
If the S600+ is currently running, you must first set the run mode to 
Cold Start.  
Note:  The key sequence you use to access the System Status page 
may vary, based on the displays for your application.  
1.  From the S600+ Startup menu, select SYSTEM SETTINGS.  
2.  Select SYSTEM STATUS.  
3.  Press CHNG.
