9. Alarm

Type of alarm

Description

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.

Sensor failure

Notifies that the feed back sensor doesn’t work

 

properly. SNSR ALARM lights up, and the

 

signal for sensor failure is output.

CPU failure

Notifies that CPU fails due to noise. All LEDs

 

Flashes, and the signal for CPU failure is

 

output.

Electrode needle

Notifies when the maintenance of the electrode

maintenance

needle is necessary. NDL CHECK ALARM

 

lights up, and the maintenance output signal is

 

output.

How to reset

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.

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.

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.

Turn off the power supply and clean the electrode needle. Then apply the power supply.

The completion signal for static charge elimination is output while the dirt on the electrode needle is being detected

Because ions are discharged from the ionizer when the electrode needle is being detected, the workpiece might be charged. Therefore, the workpieces should not be mounted when the detection is executed.
