Section − 4 nVent RAYCHEM NGC-UIT Software Upgrade
Process
The nVent RAYCHEM NGC-30 UIT Software can be upgraded using a memory stick and
the USB Port on the NGC-UIT.
4.1 Upgrade Process
Step 1
Copy the entire folder labeled “Setup”, where the new NGC software version is saved, to
the USB memory stick.
Step 2
Insert the USB flash drive with the new software into the USB port on the front of the NGC
Demo Unit.
Step 3A (For UIT Software versions 1.17.34 and lower, running on a NGC-UIT)
For UIT Software versions 1.17.34 and lower, the User Interface Terminal must have
power cycled to recognize a USB memory stick. Recycle power to the NGC-UIT. This can
be accomplished by turning off and then on the power switch button on the right side of
the Demo Unit. Once the NGC-UIT program has rebooted with the flash drive in the USB
port, the program will automatically display a screen with three options as indicated below.
Step 3B (For UIT Software version 1.17.35 and higher, running on a NGC-UIT)
UIT Software versions 1.17.35 and higher do not require power cycle, the NGC-UIT can
recognize the USB stick with or without power cycling.
While NGC-UIT Program is running, insert the USB flash drive with the new software
version into the USB port in front of the Demo Unit. Wait approximately one minute until
the program displays the selection screen. This screen will indicate four options, as shown
below:
Step 4
Choose the Update NGC-UIT from USB Drive option by pressing that button on the
screen.

nVent.com | 8
Step 5
The program will prompt you to confirm whether overwrite the current program is
acceptable, See below. Press “Yes” button.
Step 6
Wait till the load process is completed.
Step 7
If the Demo Unit has not been set to the Demo Mode yet, please proceed to the Section 5
“Setting NGC-UIT Program to Demo Mode”.

Section − 5 Setting NGC-UIT Program to Demo Mode
This step needs to be completed just once on each Demo Unit in order to be used with
PLI module and standard operation. The PLI module works only with CRM boards. Since
the Demo Unit is configured as a CRMS board, this step is required to allow the PLI
module operation with the Demo Unit. We recommend that all Demo Units are set to the
Demo Mode since this step would not have any impact on the standard operation of the
Demo Unit.
5.1 Demo Mode Configuration Process
Step 1: Go to System|Password Screen
While the program is running, go to the System|Password screen and press “OK” for
entering a password.
Step 2: Enter Password
Select Level 1 Access. Enter the Password “DEMO”. Save the new password and confirm
the saved password.

nVent.com | 10
Step 3: Demo Mode Verification
Go to the System|Misc. screen. On the Top of the screen, the word “DEMO” is now added
after the software version. See Figure below.

Section − 6 Quick Start for Demo
6.1 Setup of Circuit 3
The following is a typical heat-tracing system for Circuit 3 Setup.
This is the first screen that appears when the program loads.
Step 1: Setting up Units and Language
Go to the System|Misc screen and enter the appropriate Units and Language.
Step 2: Setting Time and Date
Go to the System|Clock screen and set the time and date.

nVent.com | 12
Step 3: Setting the Network for Device(s)
Go to the Network|Device screen.
For the very first time, the Network screen will be blank. See below.
Press “Update Network” and scan all NGC-30-CRM/-CRMS (5GF-C) boards, RMM2
and/or PLI modules into the network database. The Device Addresses for the NGC-30-
CRM/-CRMS (5GF-C), RMM2 and PLI module will be scanned and a database will be
created. A device address is the number assigned via the rotary switches on the NGC-30-
CRM/-CRMS (5GF-C) board, RMM2, PLI module.
Once the database exists, no further scanning is done unless the system is forced to
update the network by activating the “Update Network” button.
If a PLI (Power Line Carrier Interface) module is detected in the scanning process, a pop-
up window will open, asking whether the PLI Mode should be changed from the default
mode of PLI-SES/SPC to the PLI-TT. Since the PLI Module Demo Unit includes a SES
and SPC Transmitter, the option “NO” should be selected.
IMPORTANT: The NGC-30 Control System can support up to 4 PLI modules. Each
PLI module can support up to 127 SES or SPC transmitters and up to 255 700-TT
transmitters. The SES/SPC and 700-TT transmitters cannot be connected to the same PLI
module.

nVent.com | 13
The Network will then be updated with the connected devices, in this case with one NGC-
30-CRMS board, one RMM2 and one PLI-SES/SPC module.
When a PLI module is detected in the Update Network process, the PLI tab will be added
to the Network and Setup Sub-Menus.
IMPORTANT: For CRM/CRMS boards and RMM2 modules, the Resources Column
indicates the RTDs that are available for use in the Setup|RTD Screen. However, the
Resources Column for PLI-SES/SPC or PLI-TT indicates the maximum number of RTDs
that could be used. Please refer to heater isometric drawings for each circuit for the
assigned transmitters/RTD addresses to each circuit.
Step 4: Setting up a Circuit
Step 4A: Go to the Setup|Circuit screen.
At initial start-up, the Setup|Circuit screen automatically displays Circuit 1.

nVent.com | 14
Step 4B: Press on the Circuit field and a pop-up window appears.
For this example, Circuit 3 was entered.
Press Enter when done.
Step 4C: Press on the ID field and a pop-up window appears.
The pop-up window is a text-editing screen that works similar to cell phone text
messaging. There are selection keys for Upper Case Letters, Lower Case Letters, and
Special Characters. The keypad portion allows text to be entered by pushing the
appropriate keys.
For this example, Pipe #3 was entered for the ID tag.
Press Enter when done.

nVent.com | 15
Step 4D: Press on the Device Address window.
A numeric entry pop-up window appears. Type in the device address (in this case, 1) for this
Circuit and hit Enter.
Step 4E: Press on the relay Number field.
Step 4E continued: This screen shows the pop-up window prior to any relay
assignment.

nVent.com | 16
Press on the word ‘Available’ to the right of #3 to assign Relay 3 as the output device for
Circuit 3.
IMPORTANT: The screen will always display which Relays are still available on this
device for Circuit assignment.
Step 4E continued: Press Enter after Relay assignment to return to the Setup
screen.
Press enter.
Step 4F: Press on the Mode field and a pop-up window appears, showing all
available control modes.

nVent.com | 17
Step 4F: Continued. Pop-up window for control Mode appears.
This pop-up window allows selection of a Circuit’s basic operating mode. The NGC-30-
CRM (5GF-C), used in this example, has available Control modes: On/Off, Always On,
Voltage, Always Off, PASC and Proportional.
Press Proportional to select this control mode and return to the Circuit setup screen.

nVent.com | 18
Step 5: Review the Fail Safe setting.
Pressing the Fail Safe toggle button alternates the Fail Safe mode between Power Off and
Power On. This selection tells the NGC-30-CRM/-CRMS (5GF-C) if the heater should be
turned on or off if all of the RTD(s) for this Circuit fail.
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.
Step 6: Go to Setup|RTDs screen.
The NGC-30 program first checks to see if the default RTD is available. On any NGC-30-
CRM/-CRMS (5GF-C) board, the first RTD input is automatically coupled with the first relay
output; the second RTD is linked with the second output relay, etc.
