PRODUCT DESCRIPTION

For medium voltage systems it is common to use two or three autoreclose shots, and, for specific applications, four shots. Using four shots, final dead time can be set for a time long enough to allow thunderstorms to stop before definitive final reclose. This scheme prevents unnecessary lockout caused by consecutive transient faults.

Description:

The ACX controller supports 32 MB of Flash memory; 12 MB are 

reserved for the OMS database and the rest is reserved for the 

operating system (Boot Loader and Application).

Note: When using the Backup to Flash command, only the OMS 

database is loaded into the Flash memory.

Advantages of Having Flash Memory

Initially it may seem redundant to include a flash memory along with 

battery-backed memory to hold application data. However, it is this 

redundancy that makes its addition attractive.

Although it is unlikely that the battery will fail or that the data in 

memory will become corrupted, there is an extra layer of protection for 

your configuration data if you can periodically lock it into flash.

Flash Files

Periodically, newer versions of the operating system are released. You 

can find and download the latest version from the Schneider Electric 

Technical Support web site. These new versions consist of one or more 

“flash files”. Workstation software (CyberStation 1.8 or higher) 

includes provisions to upload these flash files directly to the controller.

Limitations of Flash Memory

Flash memory circuits are rated for a limited number of write 

operations (minimum of 10,000 to an average expected lifetime of 

100,000). In the ACX controller, flash memory is used for storing 

completed configurations and a snapshot of data at a particular time. 

When used in this manner, the memory should last the lifetime of the 

product. To give you an idea of how many operations are available, see 

the following table.
