This nVent manual describes how both the nVent RAYCHEM Elexant 5010i, nVent RAYCHEM NGC-20 and nVent RAYCHEM NGC-30
can be programmed via the User Interface Terminal (nVent RAYCHEM NGC-UIT3-EX). The Elexant 5010i, NGC-20 and NGC-30 are part
of the same family of controllers.
The Elexant 5010i and NGC-20 is a compact networked single point heat-trace controller with an approved integral safety temperature
limiter (SIL 2). The controllers are approved for use in Zone 1 and Zone 2 hazardous areas and can be mounted directly on the
heat-traced pipe. Up to 247 individual controllers can be connected in a single RS-485 multi drop “daisy chained” network and
communicate to a central user interface, the NGC-UIT3-EX. Up to two temperature sensors can be connected directly to the controller.
The limiter has its own temperature sensor.
The NGC-30 is a multipoint electronic control, monitoring and power distribution system for heat-tracing used in process-temperature
maintenance and freeze-protection applications. The NGC-30 system can control up to 260 heat-tracing circuits with multiple
networked panels. Each panel can control up to 40 individual heat-tracing circuits and monitor up to 128 temperature inputs, with
optional power distribution. The NGC-30 is available with two output types: Electromechanical Relays (EMRs) or Solid-State Relays
(SSRs). Both types allow switching up to 60 amps at 600 Vac with single or three-phase power. Up to four Resistance Temperature
Detector (RTD) sensor inputs for each heat-tracing circuit allows for a variety of combinations of temperature control, monitoring, and
alarming. Systems can be configured for nonhazardous and hazardous locations. The ability to monitor and configure the controller
is available both locally and remotely with the nVent RAYCHEM Supervisor software.

The NGC-30 measures temperatures with 3-wire, 100-ohm platinum RTDs connected directly to the unit, or through optional Remote
Monitoring Modules (RMM2 module). Each RMM2 module accepts up to eight RTDs. The RMM2 modules are typically located near
the desired measurement location (RTDs). Multiple RMM2 modules are networked over a single cable to the
NGC-30, significantly reducing the cost of RTD field wiring. The NGC-30 system supports 260 temperature inputs via the CRM/
CRMS boards. Using RMM2 modules, an additional 128 temperature inputs can be supported for a maximum of 388 temperature
inputs. With EMRs and SSRs, the NGC-30 can be configured for On/Off, ambient sensing, and proportional ambient sensing modes.
Additionally, with SSRs, the panel can be configured for proportional, power limiting, and soft start modes.

The controllers can monitor multiple independent Electrical Heat-Tracing (EHT) parameters. The controllers 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).

National electrical codes (NEC - North America) require ground-fault equipment protection on all heat-tracing circuits. Heat-tracing
circuits equipped with 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.

The NGC-30 system is configured with a User Interface Terminal (NGC-UIT3-EX) that has LCD color touch-screen display technology.
The NGC-UIT3-EX provides a user interface for easy and efficient programming without keyboards or cryptic labels. The NGC-UIT3-EX
model used depends on the location of NGC-30 panel and the local environment.

The term “NGC-UIT3” in this document refers to any of the available NGC-UIT3 models, regardless of which model is actually installed.
All NGC-UIT3s 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-UIT3 versions described in Table 1.1 on page 5 all use the same
wiring, system interface, and programming. The NGC-UIT3s differ only in the environments in which they can be installed.

The performance, reliability and safety of your heat-tracing system depend on proper design, selection, and installation. The NGC-
UIT3-EX Software will help you configure and monitor a system that meets your requirements, but it is only a tool. It assumes
that your input is accurate, that you are familiar with heat-tracing system design and configuration, and that you will ensure that
all components of the heat-tracing system are installed, maintained and used as intended. The configuration of the NGC-UIT3-EX
Software should be reviewed by a knowledgeable engineer to ensure it is appropriate for your application. Additional information
relating to safety, design, and installation is contained in Design Guides, Installation Manuals, Data Sheets, and other literature
available from nVent. Be sure to consult these documents as needed.

Under certain conditions, the NGC-30 program will alert the user with a warning or an error message. These are typically either
because the program cannot find an acceptable answer based on user input, or because the user may need to take some additional
action to ensure the design requirements are completely met. These warnings and error messages are detailed on page 52.

If the main concern is to prevent pipes from freezing, then Power On is a good choice. However, ifthe heater is oversized and
overheating is a concern, then Power Off could be a better choice.

• The NGC-30 program first checks to see if the default RTD is available. On any NGC-30-CRM/-CRMS board, the first RTD input is
automatically coupled with the first relay output; the second RTD is linked with the second output relay, etc. (In the case an RMC -
RMM2 combination is chosen, then the user must define himself which RTD Device address is coupled with the RMC output.)
• Here an RTD has been connected to the RTD 1 terminal block, so the RTD set-up window indicates the default assignment is
already completed

• There are three blank slots available so you can assign additional RTDs to this output relay. You may desire additional RTDs if you
need a more exact temperature sampling for a temperature-sensitive fluid. If you assign additional RTDs, the lowest RTD value from
the list will be used for control temperature
• Each of the four RTDs can be independently set as Control or Monitoring only sensor. If you are using a PLI module with SES-CONT
sensors, an additional Continuity mode will be available. SeeSection 3 for more details
• See page 33 for information on how to set up additional RTDs. For this simple Circuit Quick Start example, the default set-up RTD is
used

• Input the Setpoint, Dead Band, High Temp Alarm, and Low Temp Alarm by pressing on each of the four numeric fields in turn
• For this example, the Setpoint temperature is 10°C, a dead band of 3°C and high and low temperature alarms at 149°C and –12°C
respectively
• Use the default value of 900 seconds (15 minutes) for the Temperature Alarm Filter (time delay before the NGC-30 reports any
temperature alarm) and the default value of Disable for the High Temp Cut-Out. To implement the High Temp Cut-Out feature.

WARNING:
 A ground-fault alarm means the heating cable has been damaged or improperly installed and must not be ignored.
Disabling the ground-fault trip function reduces safety and could result in sustained electrical arcing or fire. To minimize the risk of fire
if the alarm activates, shut off the power and repair the system immediately
 Setting 0 for both High and Low Current Alarms completely deactivates the Current Alarm function.
• Power Limit – This is enabled only when SSR control devices are detected (NGC-30-CRMS panel). A Power Limit setting less
than 100% will limit the “on-time” of a constant wattage heater to the percentage indicated in the entry field. This has the effect of
lowering the amount of power that the heater can produce
 Power Limiting is not recommended if self-regulating heaters are installed

The software is designed to run only on the NGC-UIT3 hardware platform. Prior to shipment, the software is installed into a
nonvolatile area of the NGC-UIT3 memory. During the initial power-up, you will see a blue background “splash” window for
approximately 30 seconds as the system software is loaded and initializes.
