•This sets the Auto Restore Local (ARL) time period.
•ARL is an alternate configurations feature that enables a control center to make changes
to the voltage regulator operation settings while actively communicating with the control.
When ARL is active, this parameter establishes the period in which a communications or
heartbeat signal must be received by the control to keep ARL active. If the signal is
not received, the control will revert back to the control settings locally stored.
