Page 5: Getting Started
Getting Started Demonstration Flow The recommended flow of the NGC-30 demonstration is as follows. You can experiment or adjust based on the audience questions or your read on their interest level. Set the Stage • Explain what it is that their looking at. Many people think this is an actual panel and not a demonstration unit. -
Page 6: Set The Stage
Set the Stage Explain that this is a demonstration model of the NGC-30 platform and not a real panel. Go through the elements of the demo unit and point out the following: Touch screen interface – revolutionizes interaction with the system and makes it •... - Page 7 Touch Screen Demonstration Panel CRMS Control Board nVent.com...

Page 8: The Main Screen
The Main Screen The Main screen displays the summarized information for each circuit. Point out: Full text circuit ID for easy identification of the circuit. • Measured pipe temperature so that you know what the present status is of the pipe •... -
Page 9: Get Someone Involved
Get Someone Involved At this point you should get someone from the audience up to actually use the touch screen for the rest of the demonstration. Good candidates are usually young engineers. They are more familiar with this type of interface. •... -
Page 10: Program A Circuit
Program a Circuit Now it’s time to have your assistant program a circuit. The approach is to provide guidance to the person operating the demo unit and letting them figure out how to accomplish what you’ve asked them to do. The real power of this exercise is in the audience seeing how little guidance is needed to actually use our system. - Page 11 Step 2: Navigate to the Setup Screen “OK, user, we want to set up a circuit, what is the first thing you think you’d do from this screen?” The user should choose the Setup tab on the top of the screen. •...
- Page 12 Figure 4: Entering the Circuit ID “Most panels will have multiple control cards so you have to define the address for the control board which you want to assign the circuit to. Where would you start?” User should touch the white box next to the words “Device Address”. •...
- Page 13 Figure 5: Assigning a Relay Number “Next we need to select a control mode.” User should touch the white box next to the word “Mode”. • Advise the user to select On/Off mode for simplicity. • Figure 6: Select a Control Mode “Now RTD’s must be assigned to this circuit.”...
- Page 14 Figure 7: Assigning RTD’s “The NGC-30 can have up to 4 RTD’s assigned as control points for the circuit. The system will control (decide whether to turn on or off) based on the lowest measured temperature value. “RTD’s can be assigned from two different sources; hardwired into the CRM Control boards or from an RMM2.
- Page 15 “The temperature set points and alarm thresholds are set in the Temp menu.” The user usually goes to the Temp menu and may begin making changes, • I usually only point out that this is where the data is entered for temperature and •...

Page 16: Alarms And The Events Lists
UIT screen should illuminate. “What we just did was to induce a ground current fault in circuit 1. The NGC-30 system responds by first disabling the circuit and then posting the red fault indicator with the word “Aknowledge”... -
Page 17: The Network Tab
The goal here is to show that the NGC-30 has built in tools that support the commissioning of the panel and assist in troubleshooting. “Let’s look at the Network tab next. This is a really powerful tool that is built into the NGC-30 system.”... - Page 18 guess what is causing an alarm when the information on these screens can tell you directly. Using this screen, the commissioning engineer can take his paperwork and go through all of the devices that are supposed to be in the system and compare that to what is listed on the NGC-UIT screen.

Page 19: Security
“The RTD menu tab shows which circuits are using which RTD’s. Because the NGC-30 system is so flexible, an RTD may be assigned to more than one circuit. This would be the case for freeze protection for example where multiple circuits can control off one ambient temperature RTD. - Page 20 Figure 14: The System/Password Screen At this point I ask if there are any questions as an hour has usually passed and the meeting will begin breaking up. Anything you get asked that you don’t know the answer to, write down and call product marketing.
