Type of battery
ER3VC
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 Table 3.1 should be used. As this is an exclusive
battery, contact Toshiba Machine at order entry.
[Battery replacement procedures]
1)
If the battery is kept removed for more than five (5) minutes, save all
programs stored in the SRAM into the personal computer. In the worst case,
all SRAM data are lost.
2)
Set OFF the MAIN POWER switch.
3)
Remove the cover from the controller.
4)
Remove the battery connector from CN2 of the X8HC printed board, then
disconnect the battery from the Tie-wrap securing the battery.
(For the battery position, see Fig. 3.5.)
5)
Set a new battery within five (5) minutes.
The lithium battery capacity decreases by natural discharge even if not used.
Use a lithium battery which is within three (3) years (kept at the room
temperature) from purchasing.
6)
Set the cover to the controller.
7)
If the battery is kept removed for more than five (5) minutes, set ON the main
power switch and load the programs from the personal computer.
If the controller has detected the battery voltage drop alarm even before the five
(5)-year replacement period, replace the battery immediately.
