1. System prompt: The set mold life has expired, please replace the mold

Cause: The set mold life has expired

Solution: Replace the mold

2. The slider return displacement deviation is more than 10mm

Cause: The fixed part of the displacement sensor is loose

Solution: Tighten or replace the loose parts

3. The slider can move up and down, but the real-time stroke display value of the slider on the touch screen is abnormal

Cause:

1) Displacement sensor installation problem

2) Abnormal 24V DC power supply voltage

3) PLC, displacement sensor or counting circuit part is faulty

Solution:

1) Check the installation of the displacement sensor and take corresponding measures

2) Please contact our after-sales service department

4. System prompt: The slider is overtraveled, please reduce the set impact stroke appropriately

Cause:

1) Slider overtravel

2) Limit sensor is damaged

Solution:

1) Reduce the set impact stroke appropriately

2) Replace the limit sensor

5. The slider cannot move when moving up and down

Cause:

1) The guide rail gap is too small

2) The control valve does not work properly

Solution:

1) Adjust the guide rail gap

2) Clean or replace the control valve and check the oil cleanliness

3) Check the control circuit

4) Please contact our after-sales service department

6. The slider is weak in striking

Cause:

1) The cylinder piston seal is damaged

2) The hydraulic system pressure is insufficient

3) The guide rail gap is too small

Solution:

1) Replace the piston seal

2) Check the pressure sensor and safety relief valve

3) Adjust the guide rail gap

7. The slider slips

Cause:

1) The back pressure of the lower chamber is too small

2) The return oil valve of the lower chamber is not closed

Solution:

1) Increase the value of the back pressure relief valve

2) Close the return oil valve of the lower chamber

8. The pipeline vibrates strongly

Cause: The pipe clamp is loose

Solution: Tighten the pipe clamp

9. Hydraulic cylinder creeping

Cause:

1) Air in the pipeline

2) Slider speed is too low

Solution:

1) Drain the air in the pipeline

2) Adjust the slider speed to the allowable range

10. Hydraulic cylinder oil leakage

Cause: Damaged cylinder guide sleeve seal

Solution: Replace the seal at the cylinder guide sleeve

11. Pipe joint oil leakage

Cause:

1) Loose pipe joint screws

2) Damaged seal at pipe joint

Solution:

1) Tighten the pipe joint screws

2) Replace the seal at the pipe joint
