 POWER LED···Indicates the state of power input and sensor connection.
 ION LED···Indicates the polarity of ions being emitted.
Illuminates when power is supplied (Green).
(Blinks when the power supply is irregular.)
 ALARM LED···Indicates abnormal states of the ionizer.
Alarm item Description Corrective actions
Gives notification of the occurrence of an abnormal current,
such as high-voltage leakage. The ionizer stops discharging,
turns on the HV ALARM display, and outputs a fault signal.
Turn off the power, solve the problem, then turn the power
on again. Alternatively, turn the discharge stop signal off,
then on.
Turn off the power, solve the problem, then turn the power
on again. Alternatively, turn the discharge stop signal off,
then on.
Gives notification of the occurrence of a failure in the CPU
due to noise, etc. All of the LED displays blink and a fault
signal is output.
