1. Touch screen prompts: System is in emergency stop state

Cause:

1) Press emergency stop button is pressed

2) Master control system emergency stop button is pressed

Solution:

1) Rotate and reset the emergency stop button on the press

2) Rotate and reset the master control system emergency stop button

2. The power cabinet cannot be powered on

Cause:

1) The air switch of the control cabinet main power supply is not closed

2) Incoming power supply problem

Solution:

1) Check whether the air switch of the control cabinet main power supply is closed

2) Check the incoming power supply

3. Touch screen prompts: Striking is limited

Cause: The limited number of strikes has been reached

Solution: Please contact our after-sales service department

4. Touch screen prompts: The actual ejection stroke exceeds 5mm, and striking is prohibited

Cause: The initial displacement deviation of the ejector rod exceeds 5mm

Solution: Check the actual ejection displacement and zero offset in the ejection setting, and add the actual value to the zero offset

5. Touch screen fault prompt: Motor winding temperature is too high alarm

Cause: Motor winding temperature is too high, or detection probe is damaged

Solution: Check the motor winding temperature and the quality of the temperature probe

6. Touch screen prompt: Encoder error, no hitting, please contact the equipment manufacturer

Cause:

1) Encoder is damaged

2) Interference, failure or damage of the middle limit proximity switch

Solution:

1) Check the encoder and encoder device

2) Check the encoder circuit

3) Adjust the distance between the upper limit and middle limit proximity switches or replace the middle limit proximity switch

7. Touch screen prompt: Driver fault alarm

Cause: Driver failure

Solution: Please contact our after-sales service department

8. Driver RDCU main control board terminal is burned

Cause: Poor grounding of the fuselage and power cabinet

Solution: Reprocess the grounding wire, and the power must be turned off before welding near the equipment, and the ground wire of the welding must be grounded nearby

9. There is striking energy, the striking action is normal, and there is no return

Cause: Q0.2 return signal line is disconnected

Solution: Just reconnect it

10. Touch screen prompt: Tonnage detection device is abnormal, please check whether it is installed and connected correctly

Cause: Tonnage detection device is abnormal

Solution: Check whether the tonnage detection device is installed and connected correctly

11. The strike start button is pressed, but the press does not strike

Cause:

1) The "mold zeroing" operation is not completed

2) The "adjustment" mode knob is set to "single mode or automatic mode"

3) There is an alarm message prohibiting striking on the "alarm information" page

4) 4. PLC is broken, there is input but no output or no input

Solution:

1) Move the downward slider to complete the "mold zeroing" operation

2) Adjust the "mode knob" to the corresponding strike mode

3) Enter the "alarm information" interface, check what alarm information causes the failure to strike, and then solve the corresponding alarm according to the instructions

4) Check whether there is input at the input point corresponding to the PLC strike, and if there is input, check whether there is output

12. Touch screen fault prompt: PLC communication connection error

Cause: The touch screen and PLC communication cable are in poor contact or disconnected

Solution: Check whether the touch screen and PLC communication cable are loose or disconnected

13. Touch screen is black or flickers

Cause:

1) Touch screen is damaged or fuse is burnt

2) 24V DC voltage is unstable, external wiring 24V may have ground short circuit

Solution:

1) Replace touch screen or touch screen fuse

2) Check whether external wiring causes 24V ground short circuit

14. Control system cannot be powered on

Cause:

1) 24V DC power supply is damaged

2) System 24V fuse is broken, no 24V

Solution:

1) Check whether DC power supply has 220V input and 24V output

2) Check whether the fuse in the fuse is intact

15. The oil distributor does not work and alarm

Cause:

1) Pointer detection proximity switch is broken

2) PLC corresponding point (I3.0) has no signal input

Solution:

1) Check the proximity switch, including the line

2) Check whether the PLC point is intact and whether there is input
