Charger shows E19 and may indicate a time or schedule error; scheduled charging does not start.

Safety first: This is a low-voltage control issue; high-voltage safety is typically unaffected, but always follow normal precautions.

• 1. Disable scheduling: If possible, turn off any delayed or scheduled charging features in the Primecom menu and attempt immediate charging.
• 2. Reset time and date: Manually set the correct time and date on the charger, then reconfigure any schedules.
• 3. Power-cycle: Turn off power for several minutes, then restore and re-enter time settings.
• 4. Firmware update: If Primecom provides a firmware update that addresses RTC issues, apply it according to official instructions.
• 5. Board replacement: If E19 persists and scheduling is required, the RTC circuit on the main control board may be defective and the board should be replaced.
