MSA 2040 C8R09A Battery

[IgorStarostov]

I have a MSA2040. In SMU An error occured on both controllers. (The coin battery in this controller module either is not present, is not properly seated, or has reached end-of-life). What type of battery does the C8R09A controller use? What is its purpose?

Hi Igor,

The battery provides backup power for the real-time (date/time) clock.

To fix the alert,I would recommend you to follow the below action.

Warning

The coin battery is not present, is not properly seated, or has reached end-of-life

 The battery provides backup power for the real-time (date/time) clock. In the event of a power failure, the date and time will revert to 1980-01-01 00:00:00.

Recommended actions

•Replace the controller module that logged this event.

Regarding what type of battery used,I am trying to get that information.Since this is an embedded part in the controller I do not have much information on it.

Also we replace the entire controller module for warnings related to coin battery.

You can also check all the events and its description in this guide https://support.hpe.com/hpesc/public/docDisplay?docId=emr_na-c03791995.

Hope this was helpful!

The battery is embedded into the controller and, as far as I know, they replace the controller itself.
