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. This helps to avoid costly downtime. Dry 

contact relays are provided for alarm annunciation back to a Distributed Control System (DCS).

1.1.4  Ground-FauLt ProteCtion aCCordinG to north ameriCan eLeCtriCaL 

Code (neC) standard

National electrical codes require ground-fault equipment protection on all heat-tracing circuits. 

Heat-tracing circuits equipped with Raychem NGC-30 controllers do not require additional 

ground-fault detection equipment, simplifying installation and reducing costs. When applying the 

IEC standards, additional RCD circuit breaker is required.

1.1.5  instaLLation 

The Raychem NGC-30 system is configured with a User Interface Terminal (NGC-UIT2-EX) that has 

LCD color touch-screen display technology. The NGC-UIT2-EX provides a user interface for easy 

and efficient programming without keyboards or cryptic labels. The NGC-UIT2-EX model used 

depends on the location of Raychem NGC-30 panel and the local environment. 

Common nGC-uit2 interface and Programming

The term “NGC-UIT2” in this document refers to any of the available NGC-UIT2 models, regardless 

of which model is actually installed. All NGC-UIT2s interface to the NGC-30-CRM, NGC-30-CRMS 

(Card Rack Relay Control Modules), PLI (Power Line carrier Interface), and the RMM2 module 

(Remote Monitoring Module). The three NGC-UIT2 versions described in Table 1.1 on page 5 

all use the same wiring, system interface, and programming. The NGC-UIT2s differ only in the 

environments in which they can be installed. 

nGC-uit2 installed in hazardous and non-hazardous indoor or outdoor Panel Locations

If the panel is located in a hazardous/non-hazardous indoor or outdoor location, the NGC-UIT2-EX 

model is required. This NGC-UIT2-EX model is specifically designed for these environments and 

meets all applicable standards. The NGC-UIT2-EX model is installed locally on the Raychem NGC-

30 panel door.

nGC-uit2 installed separately from the Panel Locations

If the user interface terminal needs to be mounted separately from the Raychem NGC-30 control 

panel, such as when the panel is in a hazardous or difficult to access location, the NGC-UIT2-

ORD-R provides a wall-mount alternative for remote mounting in a nonhazardous (unclassified) 

indoor or outdoor location.

Nonhazardous (Unclassified) Locations
•  The NGC-UIT2-ORD-R must be 

installed in a nonhazardous, indoor 

or outdoor location.

•  The NGC-UIT2-ORD-R connects 

to NGC-30 panels using RS-485 

communication wiring.
