(3) Replacement procedure of the MES interface module battery
When the MES interface module battery has been exhausted, replace the battery with
a new one according to the procedure shown in Figure 4.20.
The programmable controller must be powered ON for 10 minutes or more before
removing the battery.
Even if the battery is removed, the memory is backed up by the capacitor for a while.
However, if the replacement time exceeds the guaranteed value in the table below,
data stored in the memory may be erased. To prevent this, replace the battery quickly.
