[NOTE]
When parameter setting of the dip switches, other than dip switch-A

completion of the parameter setting.
[NOTE]
If any warning or alarm occurs during the parameter setting, the
setting session will be stopped automatically and the display will be
changed to the warning & alarm display screen.
