Battery charger – 8340
Functional description
Once all the changes have been made a copy-over can be made with 
code 22.
• Press * 22 * 2451 *.
2451 is a safety code to avoid data being changed unintentionally. If 
charging is in progress the contactors release during the actual copying 
process.
Reading parameters
The program and component circuit boards have the same design irre-
spective of the charger’s rated voltage or current. Values are set by 
storing parameters concerning the battery and charger in the parame
-
ter memory (EE-prom). These values are written during final testing of 
the device.
NOTE:
There are other parameters that are set at the factory and are not de-
scribed here. Default values are values written during the functions 
basic programming. The significance of the register is shown in the 
following table:
•Press *  register *.
