Setting of WNG (warning) output
Select a connector pin to output the warning.
The signal before selection becomes unusable. If
the same connector pin as in the third digit is
selected, a parameter error (AL.37) will be
generated.

BWNG (battery warning) output setting
Select a connector pin to output the battery
warning.
The signal before selection becomes unusable.
The setup contents are the same as in the second
digit of this parameter. If the same connector pin
as the second digit is selected, a parameter error
(AL.37) will be generated.
