Common Faults and Solutions for Quantitative Feeders

In industrial production lines, quantitative feeders are widely used for dynamic measurement, conveyance, and feeding of bulk materials. They play a crucial role in enhancing production efficiency, reducing labor costs, and enabling transparent management of production data. Any fault in the quantitative feeder can easily lead to production halts and losses. To ensure smooth production, it's essential to keep the equipment in good working condition and promptly address any issues that arise.

Here are some common faults of quantitative feeders and their corresponding solutions:

1.Inability to Communicate with Upper Computer

·Possible Cause: Incorrect feeder address setting.

·Solution: Set the feeder parameter R22 to match the upper computer.

2.No Accumulated Pulse Output

·Possible Cause: Output pulse duration too long or too short.

·Solution: Adjust the pulse width appropriately.

3.Control System Failure to Start, No Indicator Light on the Instrument

·Possible Cause: Belt deviation.

·Solution: Switch to manual mode, adjust the tensioning device at the belt's tail to guide the belt back to position, and disengage the proximity switch.

4.No Belt Load Display

·Possible Cause: Issues with sensor connection or parameter settings.

·Solution: Check the feeder's weighing connection and parameter settings.

5.No Belt Speed Display

·Possible Cause: Encoder connection issues or incorrect parameter settings.

·Solution: Check electrical connections and parameter settings for abnormalities.

6.Instantaneous Flow Fluctuations During Initial Startup

·Possible Cause: Excessive PID control coefficient.

·Solution: Reduce the P control coefficient R02.

7.Control System Failure to Start, No Indicator Lights

·Possible Cause: Unconfirmed system fault.

·Solution: Confirm the fault via the feeder control cabinet or central control.

8.Control System Failure to Start, Belt Deviation Indicated on Rear Panel

·Possible Cause: Belt deviation.

·Solution: Switch to manual mode, adjust the tensioning device to guide the belt back to position, and disengage the proximity switch.
