Aut 

to decide auto   
reset time 

*possible to preset auto reset time in case “Er” is preset   

in “rESt” mode 

*1sec~10 sec

 

rotA/ON/OFF 

to decide   
additional 
factor besides   
basic factor to   
indicate value 
in the order   

*OFF/basic factor : line voltage/average voltage   

[L1,L2,L3] to indicate orderly in every 3 sec. 

*ON : frequencty is added to basic factor   
*possible to fix one of rotated factor or to release as   

pressing "CLR" key repeatedly 

OFF 

trIP /8 ~1/trip

orderly 

*to check latest 8 trip cause   
*press "UP" or "DN" in the "trip" mode, then trip cause 

and value is shown alternatively 

*press "CLR" or ""SET" to check next event or previous 

event 

*In order to enter setup state on the way of trip condition 
check, press "DN" or "UP"

“v-oFF’ if 
voltage is not   
detected while 
working 

*oFF : disable for this mode 
*preset time:1sec~10sec 
*”v-ot” is shown initially if voltage is not detected 

during an operation, but finally ”v-oFF’ is shown after 
preset time is elapsed 

*operational condition for “v-oFF” in “out” mode   

shall be applied for this mode as well 

 

Test 

*to check if this relay is ready to work normally or not. 
*"tESt" is appeared in case the operator press "CLR" key for 3 sec or more,   

then release pressed "CLR" key when “tESt” is shown 

*Trip output(95-98) will be energized after counting down preset ovt-time 
*press “CLR” key to reset after test trip
