300A screen printer shows "Ms3-U Off" and alarm!

Fault：Control pannel shows Ms3-U Off and alarm;

As the picture shows.

There is an sensor on the lift device;'

This sensor is for "U",means UP;

300A shows Ms3-U Off;

Means this sensor is wrong;

1. The Inductive position is not up enough; move it a little up;

2. The air pressure is not enough, make the pressure up to 6-7 Bar;

3. The sensor is broken,change it.
