11.4.1
First Damage Limit
The touch down bearing inside the STP pump will be worn out caused by impact
or air in rush from outside. Also, touch down at the power failure causes wear.
The STP control unit adds the damage point at each "Disturbance" and "Mains
Failure" error. "First Damage Limit" is displayed when the accumulation point
attains the prime setting value. "First Damage Limit" cannot be reset. It is
recommended to have the STP pump overhauled as soon as possible.
