PhAS/
1P/3P
to select
phase of power
line
*1P:single phase motor/disable for phase loss & reverse
phase, voltage unbalance /voltage must be loaded
between L1 and L2
*3P:3 phase motor protection
3P
trAn/L/A
to select a base
to display
incoming
voltage
*L : to show line voltage
*A : to show average voltage
L
dt/OFF/setting
value
to preset a time
to stop
protection
function
*OFF : disable
*1~60sec/definite,adjustable
*all protective function except reverse state is stopped
during “dt”,but detected voltage is shown
OFF
ov/OFF/setting
value
to protect over
voltage
*OFF : disable
*to protect over voltage according to preset value in
"LInE" mode
*protection range : under 20% based on line input
voltage
*Auto reset is possible only after a sensed voltage
is dropped under preset valued voltage after a time
of “AUo” mode is elapsed continuously
*Auto reset is done in case line voltage is not loaded
*This mode is not available in case initial PL(phase loss)
is happened
OFF
Otc/dEF/Inv
to define
voltage-trip
time
charateristics
*dEF : definite
*Inv : Inverse
dEF
ovt/setting
value
to preset trip
delay time to
protect over
voltage
*to preset trip delay time after sensed voltage is over
preset value
*definite : 0.2∼20sec/adjustable
*inverse : 1~10 Class
1
uv/OFF/
setting
value
to preset trip
delay time to
protect ubder
voltage
*OFF : disable
*to protect under voltage according to preset value in
"LInE" mode
*protection range:over 20% based on line input voltage
*Auto reset is possible only after a sensed voltage is
risen over preset valued voltage after a time of “AUo”
mode is elapsed continuously
*This mode is not available in case initial PL(phase loss)
is happened
OFF
uvt/setting
value
to preset trip
delay time to
