“If you touch the flashing red area, the NGC-30 system will take you directly to the circuit 1
Status screen. The Alarm Reset button is highlighted in red and you can only re-energize the
circuit by pressing that button.”
•
Instruct the user to press the Alarm Reset button if they have not already done so.

Circuit 1 should turn back on.
“Let’s go back and look at the Events list. The Events list stores up to 2,000 entries. Once it
exceeds that number, it drops out the first entry and adds the most recent event. The entries
are all in plain language, easy to understand and any fault values have associated numbers
displayed, like we saw for the ground-fault event. Also, each event has a time and date
stamp assigned and the circuit number is referenced. So no secret codes to decipher,
everything is straightforward.”
“You can scroll up and down using the arrows at the bottom of the screen. Also, there is a
built in sorting function. If you touch the “Event, Press for Alarms” button, the various fault
types will be sorted and displayed. Touch once and all the active alarms are displayed. This
is very useful when working in the panel so that you don’t have to scroll around the full list of
2,000 events to see what you want.”
“The Events list can also be downloaded either to a USB stick or via RAYCHEM Supervisor so
you can keep a history or archive if you like.”

The Network Tab
The Network tab is a great asset when commissioning a system because it allows the heat-
tracing documentation to be compared directly to how the NGC-30 system thinks it is set up.
The value of this is that connections, addressing, relay and RTD assignments can be
checked prior to reviewing alarms. This significantly reduces the troubleshooting time,
especially with wiring.
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.”
•
Instruct the user to touch the “Update Network” button. The UIT shows a search
progress bar.
“When the NGC-30 system is first powered on, the commissioning engineer can come to this
screen, hit the Update Network button and the NGC-UIT will go out and search its network to
see what is connected to it. Then it will display a list of the devices it sees, the address of
those devices and the resources associated with them. This is really powerful because
nothing ever gets wired up correctly the first time and you can spend a lot of time trying to
