To act as actual complexed meter:V,I,KW,PF,KWH,Temp
*Voltage Select:110V/220V/380V/440V/480V(110V is secondary voltage of PT)
*Current Meter with CT:0.5A~3600A(Auto Range for decimal point)
*KW Meter:0.1~60000KW(Auto Range)
*Power Factor Meter:
±
0%~100%
*KWH Meter:1KWH~99999999KWH(used "K" unit LED)
*Temperature Meter:0
O
C ~ 150
O
C
*Auto Range: to indicate decimal point in conjunction with "K/Test" LED in Loader and DM

To cover a wide current range
*70 Type:0.2A ~70A/0.2A ~ 6A(0.2KW~4.4KW/AC480V) with external CT
*With external CT :0.5~3600A

High sensitive Level and Wide range for ground fault protection:30mA~ 10A
*Standard type/with external ZCT : need to use shield wire for connection between ZCT and
Z1,Z2 terminal of DSP
*Optional type : ZCT embedded
*Alarm to disconnection with ZCT:In case ZCT is disconnected with Z1,Z2 of the
converter after the control power is on,not while operating,the preset process is not
gone ahead anymore as flickering "Ec-ct"/"Off" in "Ec" mode to clear this alarm.

To realize Short,Ground fault protection by instant trip time:0.05 sec

To be acceptable for various rating of ZCT: 200/1.5mA or 200/100mV,selectable in DIP SW

Temperature arising protection of case,winding of motor:sensed by PT100:
0
C~150
O
C
*If sensed temperature is greater than preset value, motor can not start
*if PT100 is not connected and the value except "OFF" in "TEP" mode is preset ,alarm
is shown and motor can not start. hence need to preset "OFF" in "TEP" mode to make
a motor start

Various and multiple trip output of Main and Aux relay
*Main/1a(97-98):energized(trip) with an output of C-SC/F-MC/R together
*AUX/1a(07-08):acts same as main trip or one of Shoc/Ec/Uc/AL/Temp/Ec-tE/SS-tr
/Ec-ta/Ec-tb selected in "Au-o" mode
*1a(27-28):trip for Voltage protection,but possible to change into "ALLc"(lower level
alarm) in "Line" mode

To memorize 8 events of the latest trip : to contribute analyzing trouble cause and motor working
condition in conjunction with a number of lighted LED in bar graph to show a order of tripped event.

Main contactor Auto Close:In case a line power is "on" within a preset time(SDDT) after a line power
is "OFF" during a normal operation,main contactor is closed automatically after another preset time
(DOMT)
*Shut Down Delay Time:1~5sec/Adjustable
*Delay On Make Time:0(instant)~25sec/Adjustable by 5 sec unit
*Expression in mode/eg,2-3:in case power is on within 2sec after power-off,motor starts
after 15sec(3 is matched with 15sec) from the instant of power-on

Self-diagonostics:in case of pressing "test" sw in converter or pressing "CLR" key for 3 sec
or more,main trip output is tripped after counting down o-time of definite T-I characteristic or
a time of 550% to "OC" preset value in Inverse T-I Curve ,hence % of bar graph LED shows how
much time is counted down

To have safe operation ,the alarm and the execution not to start motor is done in case as follows:
*PT100 is not connected in case the value is preset in "tEP' mode
*The latest measured temperature is greater than preset value
