    seCtion 1 – introduCtion 1.1 rayChem nGC-30 1.1.1 ProduCt oVerVieW This manual describes how both the Raychem NGC-20 and Raychem NGC-30 can be programmed via the User Interface Terminal (NGC-UIT2-EX). The Raychem NGC-20 and Raychem NGC-30 are part of the same family of controllers. The Raychem NGC-20 is a compact networked single point heat-trace controller with an approved integral safety temperature limiter (SIL 2).

  • Page 5: Monitoring

    1.1.3 monitorinG Both Raychem NGC-20 and Raychem NGC-30 can monitor multiple independent Electrical Heat- Tracing (EHT) parameters. The Raychem NGC-20 and Raychem NGC-30 monitor continuously temperature, voltage, current and ground fault current leakage and report the values including alarms to the UIT. An automated self-check feature is available where the systems periodically checks the heating cables for faults and report the result to the UIT.
