SECTION 3 – RAYCHEM NGC-30 COMPONENTS AND OPERATION
The RAYCHEM NGC-30 heat-trace system is comprised of a number of modular components,
allowing the ultimate in design flexibility. This section describes the NGC-30 control and
monitoring components (excluding the optional distribution section). Appendix B, C, and D
includes the specifications for these components.
3.1 USER INTERFACE TERMINAL (NGC-UIT2)
The NGC-UIT2 is a panel mounted color LCD display with touch-screen overlay. The NGC-UIT2
includes software that interfaces with the Card Rack Modules (NGC-30-CRM and NGC-30-CRMS)
and the Remote Monitoring Module for temperatures (RMM2), Remote Monitoring Module for
Digital Inputs (RMM-DI) and Power Line Carrier Interface (PLI) module.
The NGC-UIT2 is used as a control panel, setup device and user display.
3.1.1 MULTIPLE NGC-UIT2 MODELS
There are two versions of User Interface Terminals (UITs) available as specified in Table 2.1,
“NGC-30 User Interface Terminals (UIT2s),” on page 4. The term “NGC-UIT2” in this document
refers to any of the available NGC-UITs, regardless of which model is actually installed.
Fig. 3.1 Typical NGC-UIT2 model showing NGC-UIT2-ORD-R remote user interface terminal
The physical dimensions of each NGC-UIT2 model vary; the dimensions of the
NGC-UIT2-ORD-R shown in the figure are the largest of all NGC-UITs:
• Width: 15.21” (386 mm)
• Height: 13.21” (336 mm)
• Depth: 7.09” (180 mm)
NGC-UIT2 LCD Touch-Screen Display
The NGC-UIT2-EX and NGC-UIT2-ORD-R have a 7 inch wide x 5 ¼ inch high LCD
(17.5 cm X 13.3 cm) LCD color display. All NGC-UIT2 have touch-screen technology that
provides an user interface easy and efficient programming with no keyboards or cryptic labels.
