HOUSING GP-FLYWHEEL 8N2322 - Caterpillar

Bypass
Bypass mode directly connects the incoming utility to the system load. When the system is in the bypass mode, the load is not protected. The load can be affected by a disruption of incoming power. The Bypass mode is entered by one of the following events:
Start-up
The Keyswitch (Manual)
Failure to Recover From a FaultRepeated errors that cause the system to oscillate between the bypass mode and On-line 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. Use the keyswitch in order to change the mode of the system."Bypassed-Verify" Signals - When the system is in this state, the system verifies that the correct system telemetry is present. This state is used when you are starting the system and the state is used during the recovery of errors."Bypassed-Auto Start" - This is the default state at start-up. The system cannot immediately protect the load after the system is started. During the normal operation, the system will enter Automatic Voltage Regulation mode.Automatic Voltage Regulation Mode
The Automatic Voltage Regulation Mode can be entered by one of the following events:
Start-up
Error (Flywheel)Automatic Voltage Regulation Auto Start State
The system remains in the Automatic Voltage Regulation Mode until the system is charged and until the system is able to sustain discharge. During the Automatic Voltage Regulation Auto Start State, the flywheel must achieve a rate of 45 RPM before changing to the Automatic Voltage Regulation Charging state.Automatic Voltage Regulation Charging
The system enters this state when the system starts to charge the flywheel. When the speed of the flywheel is greater than 7700 RPM, the system enters the On-line Standby state. Normally, the system enters the On-line Charging state when the flywheel reaches 4000 RPM.Automatic Voltage Regulation Verify Signals
When the system is in this state, the system verifies that the correct system telemetry is present. This state is used when you are starting the system and the state is used during the recovery of flywheels errors.Manual Mode
The manual mode is intended to be used by service technicians. When the system is in the manual mode, a technician can conduct diagnostic tests of the subsystems. This mode is only accessible to qualified service personnel.Calibration Mode
Calibration Mode is used in the factory during the initial calibration."Calibration - Calibration Point" - The system uses this state to calibrate a telemetry channel.Calibration-Energizing - This state is used during sensor calibration. This state energizes the flywheel. The flywheel spins to several hundred RPM.Calibration-Auto Adjusting - This state adjusts the commutation of the flywheel in order to maximize charging.Redundant (N+1) Option
A redundant (N+1) system is sized with an additional Multiple Module Unit. In this configuration, the loss of one MMU will not cause the system to drop the critical load. The malfunction of one of the Multiple Module Units will cause the Multiple Module Unit with the fault to be disconnected from the critical load. The remaining Multiple Module Units will continue to carry
