: Either ON or OFF depending on the situation.
· A signal indicating static electricity removal completion is output when the detection of electrode needle dirt is in progress.
Ions are emitted from the ionizer to detect electrode needle dirt and the workpiece may therefore be electrostatically charged. Perform this detection
procedure in the absence of workpieces.

output signal
Ionizer Series IZS31
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.
Turn off the power, solve the problem, then turn the power
on again. Alternatively, turn the discharge stop signal off,
then on.
Gives notification that the autobalance sensor is unable to
operate normally. The ionizer turns on the SNSR ALARM
display and outputs a fault signal.
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.
Gives notification that electrode needle maintenance is
necessary. The NDL CHECK ALARM display comes on and
a maintenance output signal is output.
Turn off the power, clean the electrode needles, and turn
the power on again.
