Preparation – save SRAM data
As a result of replacing the battery (SRAM not backed up during this time), data loss may occur
in the SRAM of the SIMOTION P320‑4 if the battery replacement takes longer than 30 seconds.
1. To avoid a lengthy repeat of the commissioning procedure, ensure that a backup of the
non-volatile data is available before changing the battery. This is performed, for example,
automatically when Windows is shutdown correctly.
2. Shut down the SIMOTION PP320‑4 or Windows correctly via:
Windows taskbar: Start > Shut down
3. Isolate the device from the power supply and disconnect all connecting cables.
Note
If Windows was not shut down properly before backup battery replacement, loss of bit values
in SRAM memory cells during battery replacement cannot be detected reliably.
SIMOTION P320-4 must then undergo an overall reset.
Tools
You will need a T10 screwdriver to open the battery compartment.
Replacing the battery
NOTICE
Switch off the device before replacing the battery
The battery can also be exchanged when the device is operating. However, we recommend
switching off the device beforehand.
NOTICE
Time setting is lost
If the battery change takes longer than 30 seconds, the time setting is deleted.
The time on the device is no longer synchronized. Time-controlled programs no longer run
or they run at the wrong time.
This can damage the system. Set the device time again.
