Lockout Condition
Once the EAGLE enters into Lockout mode the breaker is open and the electronics will be
powered up to a maximum of 20s. Once the electronics discharges completely, the Web
HMI will not be accessible. Users will be indicated that the device is in lockout condition
by flashing of the Lockout LED at the bottom of the EAGLE, every 4 to 5s.
Lockout LED can blink only after about 1 hour of charging at the minimum. Once fully
charged the Lockout LED blinks up to around 12 hours. Lock out indicator resets when
EAGLE is closed via mechanical handle and the device is powered up.
