[Cause]
An attempt was made to set a parameter that cannot be set in the timer.
[Countermeasure]
An unsupported welding timer may be connected. Before performing other operations (power-off or jogging) after the alarm occurs, use the abnormal-state recording function (‘Abnormal State Record’ in the auxiliary menu) to obtain an image backup and contact the service center. If the abnormal-state recording function cannot be used, record the conditions and operating steps up to the alarm, obtain an image backup, and contact the service center.
