Cabinet Indicator Lights
Indicator Light | Status | Description |
Green Light (Blinking) | Standby (UPS Active / Receiving AC Power) | This indicates that the UPS is active or that the cabinet is receiving AC input power. The battery cabinet is in standby mode. There is no output power (contactors are open). The battery cabinet is awaiting the power-on command. |
Green Light (Solid) | Power-on command received. | The control system has sent a power-on command (allowing the contactors to close if all systems are good). Contactors may not close or may open due to a fault (solid amber) or E-Stop condition (solid red). The green light remains solid until the power-off command is received. |
Green Light (Off) | Error exists | The Battery Control Unit (BCU) has no power, or an error occurred on powering up. If the amber indictor light is solid or flashing, the battery cabinet does not accept a power-on command. Diagnosis and corrective action is required. |
Amber Light (Blinking) | Warning (First/Second-Level) | Warning condition present that either requires monitoring or preventive action. If system was previously activated, the green indicator light remains solid, and the contactor remains closed. If system was not previously activated, or if system was deactivated, the battery cabinet may not accept a power-on command until warning is cleared. |
Amber Light (Solid) | Alarm (Third-Level) | Critical fault or condition that requires immediate action or resolution. The contactors are opened; the green indicator light may remain solid. The battery cabinet does not accept a power-on trigger from the control system while in this state. |
Red Light (Solid) | Emergency Stop (Manual Shutdown) | E-Stop was manually triggered. The battery cabinet is turned off, due to a manual shutdown. The red light is solid to signify an emergency stop condition. |
