Exhaustive Discharge Configurations
These states are the System Auto Load and Start Configurations.Auto Power Load and Start
Auto Load and Start is a software configuration operating parameter. Auto Load and Start parameters are used to determine UPS behavior when power is first applied to the input. Auto Load and Start parameters are used following an exhaustive discharge of stored electrical energy.Note: Auto Power Load and Start configurations can only be changed by qualified service personnel.

0 Manual Load on Manual Start UPS remains in Shutdown Mode when power is first applied to the input. The load will not be automatically powered. Manual operation is required to power the load and bring the UPS online.
1 (Default) Auto Load On Manual Start UPS automatically goes into Bypass mode when power is first applied to the input. Manual operation is not required to bring the UPS online. Bypass Mode
CAUTION: The load is not protected when the system is in Bypass Mode, and can be affected by a disruption of the incoming power.

"Bypass" mode power flow
Bypass Mode directly connects the incoming utility power to the critical load while bypassing the UPS system. Reference Illustration 3.Note: The load is not protected when the system is in Bypass Mode and can be affected by a disruption of the incoming power.The system enters Bypass Mode at system start-up by an operator command via the display, from maintenance monitoring software, failure to recover from a fault, or the "Keyswitch" (manual).Repeated errors that cause the system to move between the Bypass Mode and Online Mode can lock the system into the bypass mode. When the system is locked in the Bypass Mode, the user must change the mode of the system via the "Keyswitch" or UPS View.The UPS output bypass switch isolates the UPS module outputs. The System bypass circuit breaker works in parallel with the optional static bypass switch. The static bypass switch is a solid-state device that can instantaneously connect the alternate AC source to the load.Offline Modes
Verify Signals - In this mode state, the system is verifying that the correct system telemetry is present. This state is used when starting the system or when recovering from system errors.Auto Start - The default state at start-up. The system cannot immediately protect the load after the system is started. During normal operation, the system will enter Automatic Voltage Regulation (AVR) mode.Automatic Voltage Regulation Mode
CAUTION: The load is not protected when the system is in AVR mode.The AVR mode is an operating mode where output voltage is regulated to the nominal setpoint. The power factor and harmonic benefits of the UPS are also still present in this mode. However, the load is not protected when the system is in AVR mode.The Automatic Voltage Regulation Mode can be entered into by any one of the following events:
System start-up
Auto Start
Charging
Verify SignalsSystem start-up - The UPS remains in bypass until the flywheel is in standby at full speed. When
