Can I disable FC13 on an S811+?

The S811+ user manual MN03900001E states that this FC can be disabled or changed to a warning message. This is in error as this fault code cannot be changed.

Typically this fault occurs when the S811+ receives a Stop command.regardless of how long the unit has been runnning. 

It is possible for an observer to hear the audible noise the contactor(s) make when they close, but the contactor(s) may fail to seal electrically. This can be confirmed by measuring the voltage drop across the power pole when the unit is running. A voltage drop of 1 volt or less should be indicated when the internal bypass contactor is proper sealed.
