- Bateria: The internal lithium battery has a power reserve of approximately 3 years. It is not user-replaceable. If the display remains blank after prolonged power connection, the unit may need servicing or replacement.
- Inspecció: Comproveu periòdicament les connexions del cablejat per comprovar si estan ben ajustades i si hi ha signes de desgast o danys.
8. Solució De Problemes
- La pantalla està en blanc: Ensure the device is properly powered. The internal lithium battery may need charging; leave the device connected to power for a few hours. If still blank, the battery may be depleted or the unit faulty.
- El temporitzador no s'encén/apaga segons la programació:
- Comproveu si el temporitzador està en mode 'AUTO' (no en mode manual 'ON' o 'OFF').
- Verify that the programmed times and days are correctly set.
- Ensure any unused program slots are cleared (displaying '--:--').
- Confirm the current time and day are accurately set on the timer.
- Visualització de l'hora incorrecta: Recalibrate the time as described in Section 6.2. The device has an auto time error correction of ±30 seconds weekly, but significant drift may indicate an issue.
- Device not responding to button presses: Try performing a 'RESET' using a thin object. If the issue persists, the device may be faulty.
- Vol d'entrada/sortidatage Compatibilitat: Ensure that both the input and output voltages are compatible with the specific model of the timer switch you are using. For example, if you have a 220V AC model, ensure both input power and the connected load are rated for 220V AC.
9. Consells d'usuari
- Voltage Verificació: Comproveu sempre el voltage rating of your specific timer model and ensure it matches your application's input and output requirements to prevent damage.
- Program Clearing: When setting programs, make sure to clear any unused program slots by pressing the 'RESET' button on that specific program. This prevents unintended operations from default '00:00' settings.
- Convex Buttons: The timer features convex buttons designed to prevent accidental operation. Use firm, deliberate presses when setting programs or adjusting time.
- LCD Readability: The LCD display provides clear and intuitive data. Ensure good lighting conditions for optimal readability during programming.
