6.3.3 Overvoltage alarm [
OV-A
]
When overvoltage alarm occurs, output stops and alarm maintains.
[
O-V
] ashes for 0.5 sec in the display part and the EVT indicator ashes for 0.5 sec.
Alarm clears when re-supplying power, reset, or stop the unit.
(1) Overvoltage alarm value setting [
OV-V
]
Set overvoltage alarm value within the range from 0 to 120% of the rated voltege for single-phase
model, and from 0 to 300% of the rated voltage for 3-phase model.
(2) Overvoltage alarm delay time [
OV-T
]
Set overvoltage alarm delay time within 0 to 100 sec range. After the set time, overvoltage alarm
occurs.
6.3.4 Fuse disconnection alarm [
FUSE
]
For single-phase model, when fuse disconnection alarm occurs, output stops.
For 3-phase model,
when single-phase break, it maintains output and when 2-phase break,
it stops output.
[
FUSE
] ashes for 0.5 sec in the display part and the EVT indicator ashes for 0.5 sec.
Alarm clears when re-supplying power, reset, or stop the unit.
6.3.5 Heatsink overheating alarm [
HEAT
]
When the temperature of a heat sink is over 75°C, heat sink overheating alarm occurs. [
TEMP
]
ashes for 0.5 sec in the display part and AL1 or AL2 indicator turn ON. When heatsink
overheating alarm occurs, output stops and alarm maintains. Alarm clears when re-supplying
power, reset, or stop the unit after cooling a heatsink.
6.3.6 Element error alarm [
SCR
]
Even though output is 0% and 10% of rated current or over current ows for over 3 sec (or over 5
cycle) continuously, element error alarm occurs.
When element error alarm occurs, output stops and alarm maintains. [
SCR
] ashes for 0.5 sec in
the display part and the EVT indicator ashes for 0.5 sec.
Alarm clears when re-supplying power, reset, or stop the unit.
