12.2 Replacing the Basic Module Battery
The Basic Module has one replaceable built-in battery. This battery is used to back up data
to prevent the data stored in the memory from being lost when power is interrupted (e.g.,
when the power supply to the Basic Module is turned OFF).
The built-in battery can retain the contents of the memory until the total time of power interruptions
reaches one year. The warranty period of the battery is five years from the date of purchase. These
values, however, differ according to the operating conditions, including the ambient temperature.
If the BAT indicator on the Basic Module lights, replace the battery with a replacement battery
(JZSP-BA01) within two weeks. Any delay in battery replacement will result in the data stored in the
memory being lost.
The appearance of the battery is illustrated below.

12.2.1 Procedure
1.
Save the data stored in the Motion Board to a compact flash memory, hard disk on an
external computer, or other media.
This data is used to restore any data accidently lost during battery replacement.

For information on saving methods, refer to the MPE720 Programming Device Software for
MP900/MP2000 Machine Controllers User’s Manual (Manual No. SIEPC88070005

).
2.
Check that the RDY indicator on the MP2300 Basic Module is lit.
3.
Open the battery cover on the unit front surface.
4.
Remove the connector on the end of lead of the built-in battery from the connector on
the MP2300 Basic Module. Then, remove the built-in battery from the battery holder.
5.
Insert securely the connector on the end of the lead of the replacement battery into the
connector on the MP2300. Then, insert the replacement battery into the battery
holder.
6.
Check if the BAT indicator on the MP2300 is unlit.
7.
Close the battery cover. This completes replacing the battery.

There is danger of electric shock if the battery is not replace correctly. Furthermore, machine malfunction may
occur, the operator may be injured, or the machine may be damaged. Allow only a qualified technician trained
in safety procedures to replace the battery.

When replacing the battery, always do so with power supplied to the Basic Module. If power to the Basic
Module is turned OFF when the battery is replaced, data stored in the memory in the Module may be lost.

Do not touch the battery electrodes. The battery may be destroyed by the static electricity.
