Inspect the explosion-proof seals quarterly to ensure they are intact, and replace any worn seals to maintain IP protection.

Field Fault Repair Cases

Below are three real-world, short fault repair cases to help maintenance teams quickly diagnose and resolve common issues with the listed spares, minimizing downtime and ensuring the safe operation of critical systems. Each case focuses on common problems, practical diagnosis, and simple repairs—aligned with the products we supply.

Case 1: ST40-IP PTZ Camera Station Illumination Failure in Oil Refinery Zone 1 Area

Problem: An ST40-IP Explosion Protected IP PTZ Camera Station with Illumination in a Zone 1 oil refinery failed to activate its LED illumination at night, resulting in poor low-visibility surveillance. Diagnosis: The illumination wiring was loose due to constant vibration in the refinery, and the LED array had accumulated dust and oil residue, reducing functionality. Repair: Disconnected the camera power, reconnected and secured the loose illumination wiring, cleaned the LED array with a specialized industrial degreaser, and tested the illumination (120m range) in low-light conditions. Result: The ST40-IP’s illumination resumed normal operation, providing clear night vision for 24/7 surveillance in the Zone 1 area. Preventive Measure: Added quarterly inspection of illumination wiring and monthly cleaning of the LED array to the maintenance schedule, and installed a vibration-dampening mount (YHZ-B5) to reduce wiring strain.

Case 2: YHIP-800B Digital Telephone Station Audio Failure in Mining Tunnel

Problem: A YHIP-800B digital wall-mounted telephone station in a mining tunnel failed to transmit clear audio, with background noise overwhelming communication. Diagnosis: The microphone was clogged with dust, and the noise cancellation feature was disabled due to a loose wiring connection. Repair: Cleaned the microphone with a compressed air can to remove dust, reconnected and secured the loose wiring, and re-enabled the noise cancellation feature via the telephone’s control panel. Tested the telephone with the control room to verify clear audio transmission. Result: The YHIP-800B resumed clear two-way communication, with noise cancellation effectively reducing background mining machinery noise (85dB). Preventive Measure: Added monthly cleaning of the microphone and quarterly inspection of wiring connections to the maintenance schedule, and installed a dust cover over the microphone to prevent debris buildup.

Case 3: Explosionproof Strobe Light dSLB20 Malfunction in Marine Offshore Platform

Problem: An Explosionproof Strobe Light dSLB20 (GOST approved) on a marine offshore platform failed to emit flashes, risking aviation safety. Diagnosis: The strobe light’s bulb was burned out, and the enclosure had accumulated salt spray, causing a short circuit in the wiring. Repair: Replaced the burned-out bulb with a compatible 15J xenon bulb, cleaned the enclosure with fresh water to remove salt residue, and inspected and repaired the shorted wiring. Tested the strobe light to ensure bright, consistent flashes (visible up to 1.5km). Result: The dSLB20 strobe light resumed normal operation, ensuring aviation safety for the offshore platform. Preventive Measure: Added bi-annual bulb replacement and monthly rinsing of the enclosure with fresh water to the maintenance schedule, and applied an anti-corrosion coating to the wiring to prevent salt-induced short circuits.
