WARNING
Do not connect/disconnect equipment unless power has been switched off or the area is known to be non-hazardous.
IMPORTANT
- Use appropriately classified and listed Power Supply (Limited Power Source, or LPS). Follow all applicable wiring codes and regulations.
- Peripheral equipment must be suitable for the location in which it is used.
- There are no non-incendive circuits or non-incendive field wiring within or associated with the unit.
- Only technically qualified service personnel are permitted to install or service the equipment.
- Do not disassemble the system – no user-serviceable parts inside.
- Do not operate the equipment if it has been damaged.
Provide a Suitable Panel Enclosure, and Determine Locations for NGC-UIT3-EX Assembly in Panel
- Provide a suitable panel enclosure
To protect its electronic components, the Raychem NGC-UIT3-EX must be mounted in a panel with a minimum IP32 (Type 1) enclosure for non-hazardous indoor locations. An IP52 (Type 12) or better enclosure is recommended. An IP54 (Type 4) or better enclosure is required for hazardous locations. The NGC-UIT3-EX assembly comes with a sealing gasket and hardware to mount the enclosure.
Note: The NGC-UIT3-EX is designed for operation in ambient temperatures from –40°C to 60°C (–40°F to 140°F). If the ambient temperature is outside this range, a space heater and/or cooling fan will be required in the panel.
- Determine locations for the NGC-UIT3-EX assembly in the electrical panel
The NGC-UIT3-EX should be located on the front of the panel near eye level (for convenient viewing). The NGC-UIT3-EX assembly is an electronic unit and must not be located where it will be exposed to strong magnetic fields or excessive vibration.
Conditions of Safe Use in Hazardous (Explosive) Atmospheres: The equipment must be installed in a low-risk mechanical danger environment. The equipment shall only be used in an area of at least pollution degree 2, as defined in IEC/EN 60664-1.
The equipment shall be installed in a back enclosure with tool tool-removable door or cover that provides a degree of protection not less than IP54 in accordance with IEC/EN 60079-0 rated for- Internal and external ambient of: -40ºC to +60ºC
- ATEX / IECEx: Zone 2 or better
- US / CAN: Class I Div 2 or better
Provisions shall be made external to the equipment to provide transient protection at a level not exceeding 140% at the power supply terminals
Cut Opening and Mount NGC-UIT3-EX on Front of Panel
- Locate the NGC-UIT3-EX on the front of panel
Locate the NGC-UIT3-EX assembly on the front of the panel at a level convenient for viewing. Make sure the cover on the back of the assembly will not interfere with existing panel hardware.
Note: Cutting the opening for the display is a craft-sensitive procedure; if it is not done correctly, the panel door can be damaged. The procedure for laying out and cutting the opening for the display must be undertaken with care, and by personnel qualified and experienced in panel construction. - Prepare and mark the position of the display opening and mounting holes
- Use the cut-out directions to lay out the opening for the NGC-UIT3-EX display.
- Apply two layers of masking tape around the outer perimeter of the intended opening to prevent scratching the panel surface with the jigsaw.
- Cut the display opening
Cut the opening for the NGC-UIT3-EX with a jigsaw using a 24 TPI blade. Take care not to damage the panel door. Remove all rough edges and burrs with a metal file before proceeding. - Drill the mounting holes
Drill the 12 holes with a #16 (3/16 in) drill bit to mount the NGC-UIT3-EX assembly in the panel.
Note: The following steps are most easily accomplished if the panel door is on a horizontal surface. - Mount the user interface assembly onto the panel door
- Place the NGC-UIT3-EX assembly in position; the twelve studs go through the twelve holes on the NGC-UIT3-EX assembly mounting plate (see figure below).
- Place the supplied 6/32 in Kep nuts on each of the twelve mounting studs. Fasten only hand tight.
- Look at the front of the panel, and align the NGC-UIT3-EX assembly so it is level (loosen nuts if necessary to reposition the NGC-UIT3-EX assembly).
- After the display is properly positioned, tighten the nuts to 0.62 newton-meters (5.5 inch-pounds) of torque using a 8 mm (5/16 in) in-line torque wrench. Do not overtighten and risk damage to hardware.
- Tighten Kep nuts in the sequence shown for proper sealing.
- Place the NGC-UIT3-EX assembly in position; the twelve studs go through the twelve holes on the NGC-UIT3-EX assembly mounting plate (see figure below).

NGC-UIT3-EX Connection Diagram
Connect Power
Connect 12 Vdc to the male power connection fitting located on the left side of the NGC-UIT3-EX. The “+” lead should go to the terminal marked “9–30 Vdc” and the “–” lead should go to the terminal marked “GND”. Ensure the cables are routed through the cable clamp as shown.
Note: The NGC-UIT3-EX is rated for 9–30 Vdc. Since the NGC-30-CRM modules are rated for 12 Vdc, we have used this voltage to also power the NGC-UIT3-EX. As a result, the recommend alarm relays and lights detailed in the “Additional Materials” are rated for 12 Vdc.
Provision shall be made external to the equipment to provide transient protection at a level not exceeding 140% at the power supply terminals.
Install Common Alarm Light and Alarm Relays
Mount the 3 alarm relays on a DIN rail inside the panel enclosure. Mount the Alarm light on the panel’s door below the touch screen.
Per the below drawing, bring 12 Vdc to the Relay Driver Output at the bottom of the touch screen, to the alarm relays and alarm light.
Per the below drawing, wire between the Relay Driver Output, alarm relays, and alarm light.
Communication
The NGC-UIT3-EX has two isolated RS-485 ports located at the bottom.
Field Side Port (RS-485-1)
The RS-485 port labeled “RS-485-1” is the field side port that is used to communicate with ModBus devices (ie. NGC-30-CRM/S, RMM2 and NGC-20).
Host Port (RS-485-2) – Optional
The RS-485 port labeled “RS-485-2” is the Host side port that is used to communicate with to a host computer (using Raychem Supervisory Software) or to a DCS.
Local Host Port (RS-232) – Optional
The RS-232 port labeled “RS-232 1” is the RS-232 port that can be used as local Host port that is used to communicate with to a host computer (using Raychem Supervisory Software). If the RS-232 port is utilized, the supplied female-to-female, 9-pin null modem adaptor cable must be used.
RS-485 configuration switches
The configuration switches are found on the bottom side of the NGC-UIT3-EX. Refer to the table below for settings.
| Position | |||
| Switch | On | Off | Comments |
| Pull-down | (As-shipped default) RS-485 network “–” signal is forced to a determinate state when idle. | RS-485 network “–” signal is not forced to a determinate state when idle. | One device (typically this NGC-UIT3-EX) on the
RS-485 network should force the network “-“ signal to a determinate state. |
| Pull-up | (As-shipped default) RS-485 network “+” signal is forced to a determinate state when idle. | RS-485 network “+” signal is not forced to a determinate state when idle. | One device (typically this NGC-UIT3-EX) on the
RS-485 network should force the network “+“ signal to a determinate state. |
| Termination | (As-shipped default) RS-485 network is terminated with 120-ohm resistor. | RS-485 network is not termi- nated. | Terminate the device (NGC-UIT3-EX or other) that is at each end of the RS-485 network, for a total of two terminated devices. No other devices on the network should be terminated. |
Reset switch
The Reset switch can be found on the bottom of the NGC-UIT3-EX. A pointed object is required to press the reset switch and restart the NGC-UIT software.
Servicing
The NGC-UIT3-EX contains no user-serviceable parts. Contact your Chemelex representative for service and a return authorization number if required.
Cleaning
The touch screen area of the NGC-UIT3-EX may be cleaned with a damp cloth. Typical window cleaning agents may be applied to aid in the removal of dirt, dust and grease. Do not use abrasive cleaners.
