4.3 Reset Failure and Position Overranging of Lifting Motor
Fault description:
The lifting motor is at the abnormal position and cannot run to the designated position.
Troubleshooting:
1. Check whether the motor shading plate and lifting photoelectric switch can sense each other.
2. Insert and extract the power cord of lifting motor and photoelectric switch wire of lifting motor again,
restart the instrument (the shading plate must be lower than the photoelectric switch position before the
instrument is restarted) to check whether the lifting motor runs (whether the rotating sleeve frame moves
up and down normally) and check whether 2 red indicators of lifting photoelectric switch wire are
normally on and whether the fault exists.
3. When the instrument is powered on, gently pull the belt above the running top plate with the hand and
check whether the belt has a small amount of displacement. If so, it proves that the connection between
the lifting motor and the motor synchronous belt pulley is loose.
4. If all above items are normal, replace the main control panel. Before replacing the main control panel,
you need to enter the commissioning mode to record all motor parameters. After replacement, enter all
parameters manually and check the loading position of the stirring sleeve and the magnetic absorption
position.
Maintenance Method:
1.
If the shading plate and photoelectric switch cannot sense each other, re-adjust the position of the
shading plate, place the shading plate at the central position of 2 corners of the photoelectric switch, and
the distance between the shading plate and the photoelectric switch shall be appropriate (it can shield the
photoelectric switch signal without contact).
