delay time to preset time to make a trip when Load(KW) or C
exceeds preset value

on to protect
Locked Rotor
*OFF:disable for this mode
*ON
-Otc=Def/Inv:dt+0.1sec if starting current
exceeds 300% to oc during dt, Lc is shown in
trip
*In case Load is selected ,this protection is done by
imaginary oc value calculated internally by the
relationship of V,I,PF,Effeciency.

SS/oFF/on To protect Short
circuit *oFF:This function is disable only for starting
time(dt),After dt is elapsed,this function is able
*on:This function is able from starting point

Setting
Value To preset short
protection % to
OC *Preset % to “OC” is 800%~2000%
*If KW is selected, the imaginary "OC" value
such as a case of "Lc" is adopted to execute short
protection
*OFF:this mode is disable
*Available current range for 70 type is 0.2A~
10A ,so if the current over 10A for “OC”
protection value is preset, this mode is displayed
like “SS—“”
*In case of the usage with external CT is naturally
based on 0.2A~6A
*AUX(07-08) output is available to operate
MCCB with enough current capacity as SS-
tr is selected in “Auo” mode
OFF

/Setting
Value To protect
mechanical shock
during motor is
working *to preset a value in each current range
*Preset range is 180% ~700% to OC setting value
*In case of 70 type , this upper level % must be
limited by this formular as {(200/OC preset
value) *100[%]
*OFF:This mode is disable
*If KW is selected, OC value above formular is
still applied for this protection. oFF
st /setting
value To preset a time
for shock
protection *0.05/instant,0.1~3 sec/definite
*If "Shoc" mode is oFF, this mode is displayed
like a image of "st --",it means that user is not able
to input a value anymore “—“

current *ON:to make a trip to protect phase loss based on
load current:1~5sec/adjustable
*OFF:to make this mode disable
*Auto reset is not possible,but manual reset.

on to protect reverse
phase by load
current *OFF:not to protect reverse phase
*ON:to make a trip to protect reverse phase based
on load current within 0.5 sec
