HMI control unit.
The left side of the LCD display is reserved
for the single line diagram. The right side is
for plain text visualization such as measure-
ment and protection events. The LCD back-
light is switched off automatically after 20
minutes of inactivity.
The HMI is a complete system for the local
management of the switchgear. The HMI
allows the operator to set the protection func-
tions, operate the primary objects, visualize
measurements and events, reset alarms and
change the unit working mode.
