10. Alarm function
When the state of the device becomes abnormal, the condition is displayed by alarm code by LED digit (red) on the left side of key sequence ‘0-0. Output
monitor (basic screen),’ and the decimal point of the digit starts flashing to alert the operator. The alarm function consists of power failure, overcurrent,
hardware error, heater break error and input error.
For alarms other than input error, you can select to output each of the alarm contents to alarm contact output (AL) by key sequence ‘1-3 to 1-6 ･･･ alarm.’
Alarms are not displayed when other than key sequence ‘0-0. Output monitor (basic screen)’ is displayed, but the decimal point of the left side LED digit
(red) flashes.
 CAUTION
When an alarm occurs, we recommend you turn off the power, remove the cause, and then turn the power back on.
Alarms
*If multiple alarm causes occur at once, display is as follows:
” ”  ” ”  ” ”  ” ”  ” ” 
The alarm function contents are indicated in the following:
10-1. Power failure (Power error)
A power failure alarm occurs when power supply frequency exceeds the 40 – 70 Hz range or when power supply frequency is unstable.
When the alarm occurs, output stops and an alarm is displayed.
At this time,

is displayed in the alarm display of the left LED digit, and

is displayed in the data display.
(Output standby status, key sequence ‘0-0. Output monitor [basic screen]’ only displayed)
Output is automatically reset if abnormal state is eliminated.
Set key sequence ‘1-3. Power failure alarm’ when outputting power failure alarm to optional alarm contact output (AL).
10-2. Overcurrent (Current error) / (optional)
The built-in overcurrent circuit is triggered when the output current value exceeds 130% of the rating and an overcurrent alarm occurs.
When the alarm occurs, output stops and an alarm is displayed.
At this time,

is displayed in the alarm display of the left LED digit, and

is displayed in the data display.
(Output standby status, key sequence ‘0-0. Output monitor [basic screen]’ only displayed)
Operation remains stopped. To reboot, turn off the power once.
Set key sequence ‘1-4. Overcurrent alarm’ when outputting an overcurrent alarm to alarm contact output (AL).
10-3. Hardware error (optional)
A hardware error alarm occurs when a thyristor error occurs (current continues to flow even if the thyristor device shorts and output is 0%).
When the alarm occurs, output stops and an alarm is displayed.
At this time,

is displayed in the alarm display of the left LED digit, and

is displayed in the data display.
(Output standby status, key sequence
‘0-0. Output monitor [basic screen]’ only displayed)
Operation remains stopped. To reboot, turn off the power once.
Set key sequence ‘1-5. Hardware error alarm’ when outputting hardware error alarm to alarm contact output (AL).

CAUTION
Do not apply the power to the device with no load. If a hardware error alarm occurs even if a load is connected, repair is required.
