The battery should be replaced in any of the following three cases:

 

1. Clock Data displays as Letters (A, B, C, D, E, F, etc.)
- If the letters appear instead of the correct time, you can temporarily resolve this by resetting the time from the Main Menu.

 

2. Message appears after power reset: [Changed Logging, Recipe. Do you want to initialize?]
- This message appears after turning the power OFF and then ON.
- Press the [Yes] button to proceed with initialization, and it initializes (delete) only the Logging and Recipe data.

 

3. Device resets when moving to an Alarm Screen
- If the device resets when accessing an alarm-related screen, you can execute the [Backup Memory Initialization] from the Main Menu.
- Backup Memory stores Logging, Alarm, and Recipe data. (*Note: Only the Backup Memory should be initialized. Do not reset other settings.)

 

While the device can still be used after performing the steps above, these are signs that the battery is failing.
To prevent recurring issues, the battery should be replaced.

 

How to check and replace the battery
- Check the CR2032 battery located on the back of the device.
- If the voltage is below 2.8V, the battery should be replaced.
- Power OFF the device before replacing the battery.
*Note: Replacing the battery does not affect the screen program (project/design), as it is stored in Flash memory and will remain intact.

 

If the new battery drains within a month
- If a new CR2032 battery is discharged within one month, you need to exchange the rechargeable battery (MS621) on the mainboard from customer service.
- The typical lifespan of a CR2032 battery is at least one year, but battery life may be shortened depending on the installation environment. 
- The replacement cycle is based on the battery’s lifespan under the product’s rated operating conditions.
*Note: The battery-related issues can often occur in environments with corrosive gases.
