WRENCH-SET 3863239 - Caterpillar

On-line Modes
Illustration 1 g00989862
On-line Mode"Online" - The "Online" mode is the standard operating mode for the system. When the system is in this mode, the load is protected. The system is capable of discharging in order to support the load."Online Charging" - The system enters this state when the flywheel reaches 4000 RPM. The system is charging in this state. The system can sustain discharge in this state."Online Standby" - When the speed of the flywheel reaches 7700 RPM, the system is in the "Online standby" state. This is rated idle speed for the flywheel.

On-line DischargingOn-line Discharging - The system is in this state when the unit is supplying power to the load. If there is a disruption in power, the system will change to this state.Bypass Modes
Illustration 3 g00990003
Bypass ModeBypass - 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. The system will enter the Automatic Voltage Regulation mode during normal operation. 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 - The system remains in the "AVR" 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 reaches 7700 RPM, the system enters the On-line Standby state. The system enters the On-line Charging state when the flywheel falls below 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. This state is used during the recovery of errors of the flywheel.
