has been reloaded with a newer program revision than the factory
revision, the controller will not allow language files to be downloaded from the application
memory. This is because there is a risk that the language files are not compatible with the new
revision. Therefore, you are limited to the two languages you have downloaded using E tool

18.6 Changing the battery
This procedure requires knowledge of proper ESD protection; i.e. an earthed wristband must be
used!
When the alarm ”Internal Battery” is activated and the battery LED lights up red, the battery for
backup of program memory and real-time clock has become too weak. The battery is replaced as
described below. A backup capacitor saves the memory and keeps the clock running for at least 10
minutes after the power supply is removed. Therefore, if the battery replacement takes less than 10
minutes, there will be no need to reload the program, and the clock will continue to run normally.
The replacement battery must be of the type CR2032.
