QUICK START FOR DEMO
SETUP OF LOOP 3
The following is a typical heat-tracing system for Loop 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�

6 | nVent.com
Step 2: Setting Time and Date
Go to the System|Clock screen and set the time and date�
Step 3: Checking the Network for Device(s)
Go to the Network|Devices screen�
Press “Update Network” and confirm all NGC-30-CRM/-CRMS, RMC and/or RMM2s have been
scanned into the Network database�
At first start-up, the program scans for the Device Addresses for the NGC-30-CRM/-CRMS,
RMC and RMM2, and a database is created� Once the database exists, no further scanning is done�
A device address is the number assigned via the rotary switches on the NGC-30-CRM/-CRMS,
RMC or RMM2 board�

Step 4: Setting up a Loop
Step 4A: Go to the Setup|Loop screen�
At initial start-up, the Setup|Loop screen automatically displays Loop 1�
Step 4B: Press on the Loop field and a pop-up window appears�
• For this example, Loop 3 was entered
• Press Enter when done

8 | nVent.com
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�
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 Loop and hit Enter�

nVent.com | 9
Step 4E: Press on the Relay Number field�
Step 4E continued: This screen shows the pop-up window prior to any Relay assignment�
• Press on the word ‘Available’ to the right of #3 to assign Relay 3 as the output device for Loop
3� NOTE: The screen will always display which Relays are still available on this device for Loop
assignment�
Step 4E continued: Press Enter after Relay assignment to return to the Setup screen�
• Press enter�

10 | nVent.com
Step 4F: Press on the Mode field and a pop-up window appears, showing all available
controlModes.
Step 4F Continued. Pop-up window for control Mode appears�
• This pop-up window allows selection of a Loop’s basic operating mode� The NGC-30-CRM,
used in this example, has available Control modes: On/Off, Proportional, PASC, Always On,
Always Off, and Voltage�
• Press Proportional to select this control mode and return to the Loop setup screen�

nVent.com | 11
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 if the heater should be turned on or off
if all of the RTD(s) for this Loop 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 board, the first RTD input is automatically coupled with the first relay
output; the second RTD is linked with the second output relay, etc�
• Here an RTD has been connected to the RTD 3 terminal block, so the RTD set-up screen
indicates the default assignment is already completed�
• There are three blank slots available so that additional RTDs can be assigned to this
output relay� Additional RTDs may be desired if a more exact temperature sampling for a
temperature-sensitive fluid is needed� If additional RTDs are assigned, the lowest RTD value
from the list will be used for control temperature�

12 | nVent.com
Step 7: Go to the Setup|Temp screen�
• Input the Setpoint, High Temp Alarm and Low Temp Alarm by pressing on each of
the four numeric fields in turn, and enter the values using the pop-up number pad�
Press Enter when done�
• For this example, the Setpoint temperature is 65°C, and high and low temperature alarms at
80°C and 50°C respectively�
Step 8: Go to Setup|G�F� screen
• Input the Ground Fault Alarm and Ground Fault Trip by pressing each of the two numeric fields
in turn, and enter the values using the pop-up number pad� Press Enter when done�
• For this example, the Ground Fault Current Alarm and Ground Fault Current Trip levels are set to
20 mA and 30 mA respectively�
o At less than 20mA, the NGC-30 program takes no action� At 20 mA or more leakage,
an alarm is indicated and logged to the Events List�
o At 30 mA the output relay assigned to this Loop is tripped off�
WARNING: Fire Hazard. 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�

nVent.com | 13
Step 9: Go to Setup|Current screen�
• Input the High Current Alarm and Low Current Alarm by pressing each of the two numeric
fields in turn, and enter the values using the pop-up number pad� Press Enter when done�
For this example, High Current Alarm is set to 10 A, and Low Current Alarm is set to 0 A�
• NOTE: Setting 0 for both High and Low Current Alarms completely deactivates the Current
Alarm function�
• Input Power Limit - This input is enabled only when SSR control devices are detected
(NGC-30CRMS 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 window� This has the effect of
lowering the amount of power that the heater can produce�
• NOTE: Power Limiting is not recommended if self-regulating heaters are installed�
Step 10: Enable or Disable the Loop�
• By default once a Loop is programmed, it immediately begins to control the heater based upon
the input information
• If you do not want this Loop to activate until all Loops are programmed, go to Setup|Loop
screen, and press the Enabled toggle button once, which then takes the Loop Disabled�
To re-Enable, press the Disable button�

14 | nVent.com
Loop 3 Disabled
• On the Main menu screen, any Disabled Loop is grayed out as above
LOOPS 3 SETUP COMPLETE CONFIRMATION
After completing the Setup for Loops 3 and Loops are Enabled, go to the Main screen to confirm all
Loops are activated and working properly�
