Replacing battery in OSAI controller (104 spare alarm)

Modified on Wed, 4 Mar at 8:07 AM

The battery is a CR1220. To take out the battery, follow these instructions attached (OSAI battery change).

Next, follow the 104 alarm instructions (attached) if you still have the 104 spare alarm.

Some notes:

The estop 104 error on the OSAI controller is typically caused by a depleted CMOS battery, which we have successfully resolved by replacing the battery before. Here are the step-by-step instructions:


1. Power off the machine completely and disconnect the main power supply to ensure safety.


2. Locate the OSAI controller unit and open its protective casing.


3. Find the CMOS battery on the controller's motherboard. It is a small, round, silver CR2032 battery.


4. Carefully remove the old battery by gently pressing the retaining clip and lifting it out.


5. Insert the new CR2032 battery, ensuring the positive (+) side is facing up.


6. Close the controller casing and reconnect the power.


7. Power on the machine. You may need to reconfigure the system time and date in the controller's BIOS/setup menu.
