LEDS

Each SCiB ESS cabinet has three LEDS which is controlled by each system host controller. The three LED indicators are:
1. Battery Ready (Green) – The light will come on when the batteries have reached certain State of Charge (SOC) set-
point. The light will blink if the batteries are charging but have not reached the pre-determined SOC setpoint. (See
table for more information.)
2. Discharging (Amber) – The light will come on when the UPS system is in discharge mode and the batteries are pro-
viding power to the UPS. The light will start to blink when the battery voltage has reached 98% of the cutoff voltage to
indicate the UPS system is fixing to shutdown. (See table for more information.)
3. Fault (Red) – The fault light will come on if the host controller determines there is an issue with the system. The light
will come on initially when the system is started up and turn off when the battery breaker is closed if there are no other
faults present. The light will be steady for any fault that the system can't recover from but will blink if the system can
recover from the fault. For example, loss of communication will cause the light to blink but will go off if communication
recovers. (See table for more information.)
The following table describes the front panel LED behaviors and the associated meaning.
