SW900 Display Failure Due to Incorrect P03 Voltage Configuration

The SW900 display requires the internal P03 parameter setting to match the nominal voltage of the connected battery pack (e.g., 36V, 48V, or 52V). If the P03 setting is configured incorrectly, the display's internal logic may detect a voltage discrepancy during the boot sequence. This mismatch can cause the display to fail to initialize or trigger an immediate shutdown to protect the electronics, even if the physical power delivery from the battery and controller is otherwise stable.
