is happened for presetting time

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)
