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 0.0 to 120.0% of rated voltage.
(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
]
When fuse disconnection alarm occurs, output stops. [
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.
