I have the same issue, and pushing the white illuminated button didn't fix the issue. instead, whenever I press the button the 20200 limit switch opened by SC is triggered.

This small battery is a "CRXXXX" button type.
It is located on the PCB of DSQC 639 (or previous reference) computer unit. In a standard controller, you'll find this box on the roof of the controller.
If maybe you have a compact controller, it's the same location, but it won't be a DSQC 639 but another reference. In any case, it's inside the computer unit (the box where you insert Compact flash if that helps
)You can change it by yourself, but you'll lose the date and time parameters. That will lead to show a false "maitenance counters" and so on, when you look at that is the SIS datas.
Just reply here if you need more information
Hello there,
if I understood correctly, the only concern about changing the CMOS battery is losing date and time parameters, that means I don't have to worry about anything else correct?
Additionally, how would I resolve the date and time parameters after battery replacement?
Appreciate your time!
