11.Trip indication
Trip cause and caused value is appeared alternatively
Trip
Display
Cause
Over voltage
*trip caused by over voltage in phase
L1-L2
Under
voltage
*trip caused by under voltage in phase
L1-L2
Reverse
phase
* trip caused initially by reverse phase of
incoming power line
Phase loss
*trip caused by phase loss of incoming power
line, phase L2
*Indication is shown based on “RP” condition if
phase loss is occurred under “RP” state
Volarge
unbalance
*trip caused by voltage unbalance in L1-L2
*The difference value of [max-min] and “vub” is
shown anlternatively
Zero voltage
*to show that voltage is not sensed
*The operation voltage is dropped under 35V
while normal operation is done or zero(0)
initially
