11 MII FAMILY FAQ (FREQUENTLY ASKED QUESTIONS)
Q12
My MIGII unit has tripped clearing a system fault, and I would like to analyze oscillography, should I use
special software?
A12
ENERVISTA MII SETUP software allows saving oscillography in a COMTRADE format file (IEEE C37.111 / IEC
60255-24: Common format for transient data exchange for power systems). As the COMTRADE format chosen
is ASCII, these files can be viewed in any application accepting ASCII format (Microsoft Excel"), as well as
specific applications for viewing oscillography records, as GE Multilin's GE OSC software.
Q13
My MIGII unit has the display off but the Ready LED is ON; does that mean the relay needs to be
repaired?
A13
No, it doesn't. MII relays automatically turn off the display if in 15 minutes no key has been pressed. By pressing
any key the display turns on again.
Q14
I want to pint/view all the relay settings in one window, how can I do it?
A14
In EnerVista MII Setup it is possible to see all the settings in a single window. After the communication with the
relay, from the FILE menu of the program you can PRINT or PREVIEW the settings.
