KTE UNOSYS Digital and Analog Communication LSU Repair Services

The UNOSYS Control and Monitoring System relies on stable digital and analog communication between Local Signal Units (LSUs), field sensors, actuators, and the central monitoring network. A faulty LSU can lead to communication loss, incorrect sensor readings, alarm failures, or equipment malfunction, affecting the reliability of the entire automation system.

Our marine automation engineers provide onboard fault investigation, troubleshooting, repair, testing, and commissioning for UNOSYS LSU communication failures, minimizing vessel downtime and restoring full operational performance.
