CHAPTER SEVEN – CONVEYING SYSTEM MALFUNCTIONS

What to do if a relay protection device malfunctions

This guide provides a step-by-step approach to relay circuit troubleshooting, covering everything from identifying relay failure analysis to relay coil testing and addressing relay contact problems. In this blog, we review typical failures witnessed with these relays and the best possible diagnostic strategies to ensure they serve safely. General Purpose Relays are multipurpose and commonly found in several areas like automotive industry or home automation systems among others. If the contact does not operate (conduct electricity) even though voltage is applied to the coil, it is possible that the relay drive system (coil) is defective or the contact that opens and closes the load is defective.

Reasons for fiber optic patch cord malfunctions

In fact, contamination—including dust, fingerprints, and oily residues—is the leading cause of fiber failures, as it can lead to excessive signal loss or even permanent damage to the connector end faces. Fiber optic patch cords are often treated as low-risk consumables, yet a large percentage of optical link failures originate at the patch cord level. While this was only a minor issue, it greatly affected both the optical alignment and, as indicated by test results in the field, return loss, which ideally should be approximately -65 dB, increased to 20 dB or more because of light reflecting into transceiver modules. If your internet keeps cutting out or slows down unexpectedly, the culprit might be closer than you think — your fiber optic patch cords. Fiber optic troubleshooting is an essential skill for network administrators, technicians, and engineers responsible for maintaining and repairing fiber optic systems.
