The checkweigherhttps://www.btpackmachine.com/checkweigher/ shows that the detected product is unqualified, but the rejecting device does not reject or rejects not in place, what may cause this problem and what we should do?

1. If the rejection is not in place, check whether the system's rejection output delay and rejection hold time are set accurately.

2. Check whether the air pressure of the air compressor is normal, and check the pressure gauge.

3. Check whether the solenoid valve is faulty, test the solenoid valve by hand to see if there is any response.

4. Check whether the cylinder is malfunctioning.

5. Test whether the solid state relay reacts normally.

6. Check whether the IO controller part of the checkweigher is burned out.
