Ground Fault Trip is done if a current
greater than preset zero
phase current is kept for
Eot(earth operating time) *according to selection of DIP SW:ZCT
rating is used for 200mA/1.5mA or
200mA/100mV
Over
temperature *Trip is done if the
temperature sensed by
PT100 greater than preset
temperature is kept over 8
sec
* If sensed temperature is
greater than preset value,
motor can not start
Phase Loss by
line voltage *This protection is identified
by line voltage
*Trip time is within 0.5 sec.
*"OFF" is possible in this
mode *If each of 3 phase is a state of phase loss
in the same time,which means normal
"power off", this mode does not response
to such state
*If phase loss is happened, auto reset is
not possible,but manual reset.
Phase Loss by
load current *This protection is identified
by load current
*Trip time:1~5 sec/definite.
*"OFF" is possible in this
mode
*If phase loss is happened,auto reset is
not possible,but manual reset.
Reverse Phase by
line voltage *This protection is identified
by line voltage
*Trip time is within 0.5 sec.
*"OFF" is possible in this
mode *If reverse phase is happened ,auto reset
is not possible ,but manual reset.
Reverse Phase by
load current *This protection is identified
by load current
*Trip time is within 0.5 sec.
*"OFF" is possible in this
mode *If reverse phase is happened, auto reset
is not possible,but manual reset.

Item Description Remarks
Line Voltage Incoming Line/V1,V2,V3 or Average
voltage(selected in "trans" mode of
"cab" mode group) *110V is based on a
secondary voltage of PT
*In case incoming voltage is
zero in the same time:OFF
is shown
