Screen 15：Lower voltage alarm parameters.
The word "w-lv" is displayed on the top of the screen,
indicating that the lower voltage alarm parameter.
When the lower voltage alarm is not allowed, the screen
is shown in fig. 3-2-38: 'OFF' indicates that the lower voltage
alarm is not allowed.
When the low voltage alarm is allowed, the screen is
shown as shown in fig. 3-2-38:
The "1" indicates that the lower voltage alarm
associated relay 1.
The '190.0V' indicates primary side limit value
of the lower voltage .
"200.0v" indicates primary side return value of
the lower voltage.
The '60.0' indicates that the lower voltage alarm
delay time is 60s.
Note: the lower voltage alarm allows the default value to be not allowed; The
default value of the correlation relay is not associated; The default value is 0V; The
default value of the return value is 50V; The default value for delay time is 1800s.
Screen 16：Over voltage alarm parameter.
The word "w-ov" on the top of the screen indicates that
the over voltage alarm parameter.
When the over voltage alarm is not allowed, the screen
is shown in fig. 3-2-39: 'OFF' indicates that the over voltage
alarm is not allowed.
When the over voltage alarm is allowed, the
screen is shown in fig. 3-2-39:
The "1" indicates that the over voltage alarm
relays 1.
"200.0v" indicates the primary side limit value
