6.3 Alarm
※
1: When it cannot return by re-supplying power because fuse is disconnected or element is
error, refer to ‘8. Maintenance’.
※
2:
For single-phase model, output stops.
For 3-phase model, when 1-phase break, it maintains output and when 2-phase break,
it stops output.
6.3.1 Overcurrent alarm [
OC-A
]
When overcurrent alarm occurs, output stops and alarm maintains. [
O-C
] ashes for 0.5 sec in the
display part and the EVT indicator ashes for 0.5 sec.
When setting as [
NON
], alarm output does not occur but [
O-C
] ashes.
Alarm clears when re-supplying power, reset, or stop the unit.
(1) Overcurrent alarm value setting [
OC-U
]
Set overcurrent alarm value within 0.0 to 120.0% of rated current range.
(2) Overcurrent alarm delay time [
OC-T
]
Set overcurrent alarm delay time within 0 to 100 sec range. After the set time, over current alarm
occurs.
6.3.2 Current limit [
C-LM
]
This function limits current when using big inrush load to protect thyristor.
Especially for voltage feedback, current for load resistance value ows and it may over the rated
thyristor only voltage control. Therefore, it limits current to prevent over the rated current.
