7. Alarm
Type of alarm Description How to reset
Abnormal high voltage Notifies when overcurrent such as high voltage
leakage occurs. The ion-discharge-output is
stopped, HV ALRM sets off and output the
signal for failure.
Turn off the power supply to solve the problem.
Once it’s solved, apply the power supply again.
Or turn on and off the discharge-stop signal.
CPU failure Notifies that CPU fails due to noise. All LEDs
Flashes, and the signal for CPU failure is
output.
