Alarm
•
Supported alarms are different depending on the model.
•
When several alarms occur at same time, the highest priority error is displayed based
on priority.

• SCR error alarm
Even though output is 0%, if the current of 10% or more of the rated load current flows for
over 3 sec continuously, SCR error alarm occurs.
•
Over current alarm
This function protects the load from over current. If the current flows over the P2-7 over
current alarm value and P2-8 over current alarm delay time, over current alarm occurs.
• Heatsink over heat alarm
When the temperature of a heatsink is over 85 ℃, heatsink over heat alarm occurs.
•
Over voltage alarm
This function protects the load from over voltage. If the current flows over the P2-9 over
voltage alarm value and P2-10 over voltage alarm delay time, over voltage alarm occurs.
• Fuse break alarm
When breaking fuse, not suppling load power, breaking load (single load), fuse brake alarm
occurs. In the case of normal control model, real-time fuse break alarm is not available during
output, and fuse break alarm operates at 0% output such as RESET.
• Heater break alarm
Comparing the full load resistance value and the current load resistance value, if the current
load resistivity is maintained under the P2-12 heater break alarm value for over 3 sec
continuously, heater break alarm occurs. This alarm operates when control output is over
10% and load current is over 10% of the rated current. Output does not stop and operates
normally.
