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
• – Current Meter with CT:0.5A~3600A(Auto range for dcimal point)
• – KW Meter:0.01~66535 KW(Auto range for dcimal point)
• – Power factor Meter:+,-,0%~100%
• – Meter:0.1KWH~66535 KWH
• – Temperature Meter:0 ~150 degree C
• – Auto ramge:to indicate decimal point in conjunction with "K/Test" LED in Loader and DM
• ▪ To cover a wide current range
• – 70 Type : 0.2 ~70A/ 0.2A~6A with an external CT(“5t” must be selected in “cto”mode)
• – With external CT:0.5A ~ 3000A
• ▪ To realize Short,Ground fault protection by instant time:within 0.05sec
• ▪ 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
• ▪ 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

Remote Control through RS 485/422, Ethernet Communication

• ▪ Remote Control through RS 485/422 Digital Communicatio
• ▪ Basically 4~20mA Output:max curremnt of 3 phase
• ▪ To realize effective system for digital communication:posible to combine a module simply if neccessary
• ▪ To response for RS 485/422, Modbus
• ▪ CM-44E Model : Ethernet, Modbus TCP
• ▪ To select one of RS485 and 422:Simply selectable in DIP SW inside communication module
• ▪ To put easily termination resistance in extreme end unit:Simply selectable in DIP SW inside communication module
• ▪ To monitor and input a data in the field:Note PC converter<>in DSP
