5.4.1. Pack Connection/Status

The overall controller operation and connection status is displayed in the upper left corner of the
screen. The behavior of this graphic is the same as described in the dashboard
BMS statuses of the pack or any stack is clickable to navigate to the
warnings and faults for the pack or a specific stack. A connect button is available when automatic
pack connection has been enabled. When manual connection of a pack is configured, this connect
button is removed.

5.4.2. Stack Enable and Connection

The connected and enable state of each stack is displayed in the red/green oval. A grey button
labelled Enable or Disable is located below this status. The button will toggle the enable state of a
stack. When a stack is changed from enabled to disabled state, the stack is immediately disconnected
from the DC bus. When a non-faulted stack is toggled from disabled to enabled, there will be one of
two possible outcomes:
1. If pack auto connection is enabled, the stack is considered a candidate for connecting to the pack.
