Note:
The battery life is ten (10) years at the room temperature. As it differs with
the external environment such as operating temperature and humidity, we
recommend to replace the battery every five (5) years.
Only the battery shown in the table above should be used. As this is an exclusive
battery, contact Toshiba Machine at order entry.
[Battery replacement procedures]
1)
If the battery is to be kept removed for more than one (1) minute, copy all
programs and various parameters stored in the internal memory to the personal
computer. In the worst case, all memory data are lost.
2)
Set OFF the main power switch.
3)
Prepare a new battery, then remove the cover from the controller.
4)
Disconnect the battery connector from CN2 of the X8HC printed board, and
remove the battery from the TY-RAP securing the battery.
(For the battery position, see Fig. 3.5.)
5)
Set the new battery immediately. (If the battery is kept removed for more than
one (1) minute, all memory data are lost.)
Even if not used, the lithium battery capacity decreases by natural discharge.
Use a lithium battery which is within three (3) years (kept at the room
temperature) from purchasing.
6)
Mount the cover on the controller.
7)
If the battery is kept removed for more than one (1) minute, turn on the main
power switch and load the programs and various parameters from the floppy
disk unit or personal computer in which the TSPC (option) is already installed.
If the controller has detected the battery voltage drop alarm even before the five
(5)-year replacement period, replace the battery immediately.
