Figure 26. Example of configuration override: a failure detected during Cell Terminal diagnostics (yellow

background) causes the following two steps (red background) to be executed

4.12.3

Routine steps

The following paragraph will cover the functionality of each step embedded in the voltage conversion routine.

4.12.3.1

Cell conversion

Cell conversion is the first step of the voltage conversion routine. It is mandatory, meaning that it cannot be

excluded from routine execution, neither in On-Demand Conversions nor in Cyclic Conversions.

During this step, all the enabled cells will be converted and their voltage will be added to obtain the total stack

value.
