9. Alarm
Type of alarm | Description |
Abnormal high voltage | Notifies when overcurrent such as high voltage |
| leakage occurs. The |
| 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. |

ON and OFF status will be changed depending on the situation
・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.
