Hi all,

I have a 3M-C controller. It has been idling for long time and just recently i have it restarted. At this instance, the battery for backup is not installed and parameter are all lost but i have a copy to input so no worries.

Then i on the power from the control panel and it gives me the following message

SYSTEM ALARM : NO. 2

WORK MEMORY : Parity Low


Can anyone advise how to resolve this issue?

Thanks
