LS GIPAM 2000 User Manual

Fault display (at relay operation)
■ Basic CODE interpretation
* - The fault display on the screen about operated relay elements will disappear by pressing the Reset button ( ).
- The information disappeared from the screen will be automatically recorded/saved in the FAULT HISTORY.
* Can move to previous or next page by using .

the screen when fault occurred.
※ Basic structure
 The CODE and VALUE in the FAULT HISTORY is
same with the content displayed when the fault
occurred, and the TIME (Fault occurrence time) will
be additionally recorded.
