Information

Easy Handling

to realize convenient & various data input
- Display Meter
- Loader
- Note Book PC
Main/Sub/Cab Menu :three seperated menu according to usage and data input frequency
- Main menu :Data input frequency is rather higher
- Sub menu : ratherly common application for all kind of motor
- Cab menu(calibration menu):adjustable for indicating value within narrow range(+,- 12.7%)/this menu is appeared when “SET” key is pressed for 5 sec or more and disappeared right after pressing again
Back lit display:easy handling in dark space of the panel
To indicate a necessary in every 3 sec
- basic factor circulating indication:V,I,KW,GR/”OFF” must be set in “rota” mode
- Basic Factor + PF,temp,KWH,AWT(Accumulated working Time)/”ON” must be set in “rota” mode/Possible to fix one of circulated factor or to release:one touch for “CLR” key
- Possible to check presetting value during operation / “SET” & “MODE” key / Mode and value is shown alternatively / return to operating state without input for 10 sec or pressing “Mode” key/ not possible to preset value
- To show load factor(actual/setting)/65%~100%,Round type
Duplex Alarm : Higher Alarm,Lower Alarm to OC
To secure a safety: Password input for setting a data
ON-OFF switch/DSP-VIP-PM:to save wiring and labor inside panel
Convenient installation:65 Phi circle or rectangular hole/DSP-VIP-PM:Display Meter
To indicate tripped number of main contactor:contributing to check a replacing term and effective maintenance
To call initialized factory setting value:pressing test button before power-on and keeping a press for 3 sec after power-on.
To keep a stable operation under frequency variation of inverter:10 Hz~400Hz

Multi-complexed Function

Power type protection relay based on Voltage and Current
to indicate RMS value/Voltage,Current:RMS chip adopted in every input/to contribute to check an exact condition of motor
Provides actual meter function:V,I,KW,PF,KWH,temp
- -Voltage Select:110V/220V/380V/440V

To be acceptable for various rating of ZCT:200/1.5mA or 200/100mV,selectable in DIP SW
Temperature protection/motor winding:sensed by PT100
- Not posible to start under keeping over temperature than presetted value
- if PT100 is not connected before starting, alarm message is coming out and not allow to start.
- Above all condition can be clear as making temperature mode disable.
various and multiple output of Main and Aux internal relay
Main / 1a-1b(95-96,97-98) :energized with output of internal relay,C-M-D-Y,at same time
AUX : 1C X 1 / 07-08-10 :acts same as main trip or one of Shoc/Ec/AL/Uc/AL/Temp/Ec-tE selected in “Au-o” mode
1C X1 / 27-28-30:trip for voltage protection ,but possible to change into “ALLc”(lower level alarm) in “Line” mode
Y-Delta Starting Timer: not neccessary for additional circuit ,to save labor and space
to memoize latest number of 8 tripped cause:to contribute analysing trouble cause and keeping a data after power-off
main contactor Auto Close:in case a line power is “ON” again within a presetting time(SDDT) after a line power is “OFF” during a normal operation,main contactor is closed automatically after another presetting time(DOMT)
Shut Down delay Time:1~5 sec/Adjustable
delay On make Time:0(Instant)~25sec/Adjustable 5 sec unit
Expression in mode:eg/2-3:in case power is “on” within 2 sec after power-off,motor restarts after 15 sec(3 is matched with 15 sec) from instant of power-on.
Self-diagonostics:main trip output is tripped after counting down o-time of definite T-I or a time of 550% to “OC” Inverse T-I

Protection

Item	Description	remarks
Over Voltage	* 110V : 110~150V * 220V : 220 ~ 290 * 380V : 380 ~ 450 * 440V : 440 ~ 510	The voltage over upper level of each range makes trip of over voltage the trip caused by voltage is resetted automatically after reaching prestting value *Only 110V is based on a secondary voltage of PT
Under Voltage	* 110V : 70~110 * 220V : 150~220 * 380V : 310~380 * 440V : 370~440	The 3 phase voltage of lower level of each range is assumed Zero the trip caused by voltage is resetted automatically after reaching prestting value
Over Load (㎾)	Trip is done if the load(KW) greater than setting value is kept over prset O-time
Over Current	Trip is done if the current greater than setting value is kept over prset O-time
Under Load Under Load(㎾)	Trip is done if the load(KW) smaller than setting value is kept over preset u-time
Under Current	Trip is done if the load current smaller than setting value is kept over prset u-time
Unbalance	* trip is done if the presetted current unbalance rate is kept over 8 sec * rate=[(max. curr.- min. curr.)/max. curr.] * 100 [100%]
Locked Rotor	trip is done if 300% current greater than preset “oc” is kept for d-time plus 0.1 sec
Shock/Stall (instant over current)	* trip is done if a current greater than presetting value during working is happened for presetting time * Presetting range:180% ~ 700% Available for 10 type and 70 typetype,but upper limit for 70 type is based on [(240/OC setting value)100][%]} ,if greater than 700%, assumed 700%
Short	* available for starting instant or after d-time/selectable * Presetting range: 800% of OC~{(240/OC)*100[%]} ,maximum upper level is 2000%, operating time is within 50ms(0.05sec)	* available for 10 Type * short protection over 15A should be external CT
Ground Fault	trip is done if a current greater than preset zero phase current is kept for Eot(earth operating time)	DIP SW Selection/ZCT rating:200㎃/1.5㎃ or 200㎃/100mV
Over Temperature	P trip is done if temperature sensed by PT 100 greater than preset value is kept over 8 sec
Phase Loss by line voltage	* This protection is identified by line voltage within 0.1 sec * “OFF” is posible in the mode	* If there is a state of phase loss in the sametime,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 within 0.1 sec * “OFF” is posible in the 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 within 0.5 sec * “OFF” is posible in the 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 within 0.5 sec “OFF” is possible in the mode	* If reverse phase is happened ,auto reset is not possible,but manual reset
Main contactor Auto Close	In case a line power is “on” again within presetting time(SDDT) after a line power is “off”,main contactor is closed automatically after another presetting time(DOMT) SDDT:1~5 sec/DOMT:0(instant)~25sec/adjustable in 5 sec unit	eg.:if 2-3 is presetted,in case power is “on” within 2 sec after power-off,motor starts after 15 sec(3 is matched with 15 sec)
