SEED 01

Accuracy Declines

Machine deterioration is unavoidable over time. Accuracy will gradually decrease. To maintain performance, regular maintenance, measurement, and corrective actions are required to restore normal operating conditions. If left unattended, machine components may suffer damage. Accuracy is a barometer of machine health.

Machine Stopped

A machine stops when an alarm is triggered, but the machine itself is not yet broken. An alarm is a warning that component deterioration or abnormal wear has reached a critical level. Continuing operation may lead to serious machine failure. The entire machine should be inspected promptly, and the root cause must be removed.

SEED 04

It Stops Again

Machines are designed to restart after an alarm reset. However, repeated resets allow damage to accumulate until the machine reaches a point where it can no longer be restarted. At this stage, repair costs and downtime increase significantly, and the service life of the machine is reduced. Alarm codes indicate the abnormal movement and the location where the alarm occurred. However, they do not identify the actual cause of the problem. As a result, resets are often repeated while the root cause remains unknown.
