Diagnostic report for Cubic Relay Box persistent clicking noise. Covers symptoms, causes, solutions, and preventative measures in a retail environment.
This information is usually found on the device label. Ensure the power supply matches.
If so, the terminal may be sending errant data. Try another terminal if possible.
Shared power supplies can lead to voltage fluctuations. Dedicated is preferred.
Relay boxes typically contain electromechanical relays that switch circuits. Clicking noises usually indicate the relay armature is repeatedly opening and closing. This can result from voltage fluctuations, corrupted control signals, or mechanical wear within the relay itself. Increased baud rate can lead to faster/louder clicking.
Regularly inspect cable connections for tightness and damage. Ensure the power supply provides a stable voltage. Keep the surrounding area free from excessive dust and moisture. Maintain adequate ventilation to prevent overheating. Implement an ESD control program, particularly during dry winter months, including grounding straps for staff.
Try applying a ferrite choke to the power or signal cable of the relay box. This can help to suppress high-frequency noise that may be triggering the relay. Also, if a specific device or action consistently precedes the clicking, carefully document it. This can aid in identifying the source of interference.
