GE MM-II Relay

[burntcoil]

Greetings,
Can anyone confirm if there is clock function in GE MM-II relay. We have this relay on a motor feeder and it store just one last event but there is no time for the event. Also in the manual i could not find date and time. The software have for MM-II has installation problems.

Thanks

No. Plenty of timers, but no Real Time Clock, nor does it have a fault buffer. It only shows the current fault. You would have to move up to a Motir Protection Relay (MPR) like the 369 (I believe) before you get those features. RTCs are expensive and require s battery, so then also battery alarm processing etc. The MM2 was meant to be an entry level product, like a smart OL relay, not an MPR.
