Replacement Procedure of System-Memory Backup Battery (CR2032) for K Type (General-Purpose
Type)
Backing up the system memory
If “Other parameter No. 20, System-memory backup battery installation function type” is set to “2”
(installed), the following SRAM data in the X-SEL Controller will be backed up by the system-memory
backup battery on the panel board:
• Position data
• Coordinate system data
• SEL global data (flags, integer/real variables, string variables)
• Error lists
Therefore, the above SRAM data will be destroyed if the system-memory backup battery is removed
when “Other parameter No. 20, System-memory backup battery installation function type” is set to “2”
(installed). For this reason, always follow the procedure below when replacing the system-memory
backup battery:
[1] Turn on the controller power.
[2] Record (write down) the current setting of “Other parameter No. 20, System-memory backup
battery installation function type.” (This will be used when reverting the parameter to its original
setting following the replacement of system-memory backup battery.)
[3] If the PC software is installed in your PC, save the position data to a file using the PC software.
The data will be used as a backup in case the SRAM data saved to the flash ROM fails.
[4] Change “Other parameter No. 20, System-memory backup battery installation function type” to
“1” and transfer the setting to the controller, and then perform a flash ROM write. (The point data
will be saved to the flash ROM.)
* Confirm that the flash ROM writing process has completed.
[5] Perform a software reset (restart) to restart the controller. (The SEL global data and error lists
will be saved to the special area in the flash ROM.)
[6] When the controller has been restarted, turn off the power.
* Once the controller has been restarted, be sure to keep the power on until the initialization
sequence number is no longer displayed on the panel window (while “InXX” is displayed
following “8888”; XX indicates a number).
[7] Replace the system-memory backup battery. The battery is mounted on the panel board and
can be removed using two small screwdrivers or the like. When removing the current battery and
installing a new one, pay due attention to the following points (SRAM data will be destroyed if
steps 1 through 6 are not performed properly):
● Do not damage the board patterns.
● Do not short the circuits.
● Connect the battery in the correct polarities.
