A failure of this device – for whatever reason -- may leave an operating process without appropriate protection and could result in possible damage to property or injury to persons. To protect against this, you should review the need for additional backup equipment or provide alternate means of protection (such as alarm devices, output limiting, fail-safe valves, relief valves, emergency shutoffs, emergency switches, etc.). Contact Remote Automation Solutions for additional information.

 Returning Equipment

If you need to return any equipment to Remote Automation Solutions, it is your responsibility to ensure that the equipment has been cleaned to safe levels, as defined and/or determined by applicable federal, state and/or local law regulations or codes. You also agree to indemnify Remote Automation Solutions and hold Remote Automation Solutions harmless from any liability or damage which Remote Automation Solutions may incur or suffer due to your failure to ensure device cleanliness.

 Grounding Equipment

Ground metal enclosures and exposed metal parts of electrical instruments in accordance with relevant safety standards. For the USA, refer to OSHA rules and regulations as specified in Design Safety Standards for Electrical Systems, 29 CFR, Part 1910, Subpart S, dated: May 16, 1981 (OSHA rulings are in agreement with the National Electrical Code). For international locations, refer to instruments that include electrically operated devices such as lights, switches, relays, alarms, or chart drives. The FB3000 includes a chassis ground lug. Unless specifically noted, the chassis ground is isolated from ground terminals on individual modules installed in the device to prevent noise. The chassis ground lug provides a path to earth ground for electrical safety, static discharge, and stray voltages. Do not connect the chassis ground lug directly to a lightning arrestor/lightning rod. Important: Complying with the codes and regulations of authorities having jurisdiction is essential to ensuring personnel safety. The guidelines and recommendations in this manual are intended to meet or exceed applicable codes and regulations. If differences occur between this manual and the codes and regulations of authorities having jurisdiction, those codes and regulations must take precedence.

Emerson FB3000 RTU Instruction Manual

D301851X012

May 2022

Each slot includes an upper section and a lower section. The upper section holds the internal logic for the module and the lower section holds the personality module used for wiring.

If your RTU is not fully populated with modules, you can fill the empty slots with slot covers to protect the connectors from dust. These are installed/removed using the same screws used for personality modules.

If you require more than seven I/O slots, you can optionally purchase one, two, or three extension chassis to attach to the base chassis, allowing an additional 8, 16, or 24 I/O slots.

1.4 Central Processing Unit (CPU)

The RTU’s CPU is a Freescale (NXP) SoloX dual-core architecture processor with an Arm® Cortex A9 core, and an Arm Cortex-M4 core. If your RTU includes multiple chassis, there is still only one CPU module in the first slot of the first chassis; all other chassis hold only I/O modules.

There are two CPU versions available:



3CPU16 – FB3000 RTU with full control and I/O capabilities.



3IOCPU – FBxRemote I/O for I/O only with no control, no calculation support, and no application support.

have a wire gauge between 20 and 12 AWG.

10 Installation



To prevent shorts, ensure that no bare wire is exposed. You can also use crimp bootlace ferrules (18 to 24 AWG for I/O; 18 to 20 AWG for power).



Allow some slack in the wire while making terminal connections. Slack makes the wires more manageable and helps minimize mechanical strain on the terminal blocks.

Use twisted pair, shielded and insulated cable for communication and I/O wiring to minimize

signal errors caused by electromagnetic interference (EMI), radio frequency interference (RFI) and transients. When using shielded cable, ground all shields at a suitable Instrument Earth connection point. This prevents circulating ground current loops that can cause signal errors. See the FB3000 product data sheet for information about applicable standards for EMI and RFI emissions and susceptibility.

To avoid damage to terminal blocks, exercise care when unplugging them. Gently pull up on one end, then gently pull up on the other end, then continue alternating this way to gradually work the terminal block out of its socket.

2.5 Grounding

There are four separate and distinct ground references within the FB3000 architecture. The chassis ground lug (also known as Protective Earth or PE), internal system bus ground, isolated ground, and the 24V loop ground.

Emerson FB3000 RTU Instruction Manual

D301851X012

May 2022

Chassis Ground Lug

The RTU includes a chassis ground lug to the left of the power supply modules. In CSA documents, this may be called the Protective earthing (PE) conductor. The chassis ground lug provides a path to earth ground for electrical safety, static discharge, and stray voltage from a lightning strike.

use the chassis ground lug for a direct connection to a lightning arrestor/lightning rod.

The chassis ground lug is completely isolated from the isolated, signal, and loop power ground terminals on I/O modules, or from the 24V loop power ground terminal on some I/O modules. To prevent noise and equipment damage, you should keep these grounds separate from the chassis ground.

Installation 11

Emerson FB3000 RTU Instruction Manual D301851X012 May 2022

Figure 2-4: Chassis Ground Lug Location

 Once you have installed the unit, run a ground wire (14 AWG protective conductor)

between the chassis ground lug and a known good earth ground.

 Use stranded copper wire to earth ground and keep the length as short as possible.

 Clamp or braze the ground wire to the ground bed conductor (typically a stranded

copper AWG 0000 cable installed vertically or horizontally).

 Run the ground wire so that any routing bend in the cable has a minimum radius of 30.48

cm (12 inches) below ground and 20.32 cm (8 inches) above ground.

Note: If your installation includes multiple chassis, you must individually ground each chassis.

For more information on grounding or if your installation uses cathodic protection, refer to Site

Considerations for Equipment Installation, Grounding, and Wiring (D301452X012).

Internal System Bus Ground

The internal system bus ground provides an internal reference to system power negative or ground input. Users cannot access this ground.

12 Installation

Isolated Ground on 3MIX12 Module

The 3MIX12 mixed I/O module includes an isolated ground system (ISOGND) on pins 5, 10, 12, and 14 of TB1. ISOGND provides a low noise return (ground) for analog inputs and outputs. It is completely isolated from the other three ground systems. You can optionally enable grounding for one or both digital outputs on the 3MIX12 through individual settings for each DO in FBxConnect. When enabled, digital output(s) are internally connected to ISOGND.

Table 2-3. Extended Backplane Supported Configurations

The number of mixed I/O modules that can be supported by the FB3000 loop power connectors varies depending upon the RTU’s external power supply.

For example, if you have a 12V installation, you can see by referring to Table 2-3 that although you can install up to 21 mixed I/O modules among the base and extension chassis, only 10 can be powered through the RTU’s loop power connections; you must power the other 11 through a separate external power supply. Similarly, if you have a 24V installation, and you install the maximum of 31 mixed I/O modules; the RTU’s loop power can only power 21 of them; you must power the remaining 10 through a separate external supply.

Note: If your installation includes multiple chassis, wire power only to the left-most (base) chassis.

Note:

If your FB3000 does not power on, check that the polarity of the DC input voltage wiring connections match Figure 2

The FB3000 RTU supports a mixed I/O module which includes eight channels you can individually configure as either analog inputs (AI), digital inputs (DI) or pulse inputs (PI). The number of mixed I/O modules supported depends on the number of I/O slots in the RTU.

Note

No external resistor is required to interface with a current (4-20 mA) device. To convert a current to a voltage to be read by the hardware analog to digital converter, when you configure the AI for current within FBxConnect, the device enables a 250 ohm resistor across the channel input.

3.6 HART® Input/Output Channels (3HRT04)

The FB3000 RTU supports a HART® (Highway Addressable Remote Transducer) module with four (4) channels. This allows the FB3000 to communicate with external HART devices such as transmitters.

Insert the 3HRT04 module in any base chassis slot except slot 1 and insert its corresponding 3HTSG4 module below it.

Note

The 3HRT04 module requires a chassis of Revision H or newer.

The 3HRT04/3HTSG4 modules cannot be used in an extension chassis.

You can configure a channel for point-to-point operation in which case it communicates with a single HART device. Alternatively, you can configure a channel for multi-drop operation in which it communicates with up to five (5) HART devices in parallel.

FBxConnect as either an input or an output, but not both.

A HART input supports either point-to-point or multi-drop mode

A HART output supports only point-to-point mode; in multidrop mode, there is no analog signal output available.

3.6.1 Wiring the 3HRT04 Module

You can wire HART channels for different modes of operation.

3.6.1.1 Point-to-Point Mode

Emerson FB3000 RTU Instruction Manual

D301851X012

May 2022

In Point-to-Point mode, the HART link allows both a 4-20mA analog current mode signal as well as the modulated HART digital signal riding on top of it. Depending upon the HART device connected, you can configure the channel as an AI (which means the 250ohm resistor is enabled) or an AO (which means the 250-ohm resistor is disabled).

Figure 3-10 shows how to wire all four HART channels in point-to-point mode. In this

case, each HART channel only communicates to a single HART device. You choose whether a given channel serves as an input or output in FBxConnect. The 24V internal loop power supply powers the HART devices. The HART interface only sinks current, it cannot source current. As an output, each channel simultaneously provides an analog current signal output (sink current only at 4-20 mA) and a HART signal modulated on top of it.

3.6.1.2 Multi-Drop Mode

In Multi-Drop Mode, only the HART digital signaling (FSK – Frequency Shift Keying) is

present and can support a maximum 4mA bias current. Because the maximum rated output (sink) current of any 3HRT04 Module channel is 20mA, and each device can draw 4mA, a HART channel in multidrop mode supports a total of 5 HART devices. With each of the 5 HART devices permitted to draw 4mA, the sum of the currents is 20mA – the maximum current.

Figure 3-11 shows how to wire a HART channel for multi-drop mode. Multi-drop mode

only supports inputs, you cannot have multi-drop outputs.

You can wire each channel the same way to allow for up to 20 HART devices (5 per channel).

4.2 Establishing Communications

The RTU supports communications through the host SCADA system, or through a local laptop computer running FBxConnect.

4.2.1 Communicating with the SCADA Host

Communication to the RTU through a SCADA host computer requires configuration of the host computer software, which varies depending upon whether you are using OpenEnterprise or another host software package. Much of this configuration is beyond the scope of this topic, but no matter which host you are using, there are certain steps you must take:

1. Decide how the SCADA host should communicate with the RTU. This could be

through connection with one of the communication ports. A serial port connection could be a cable directly connected to the SCADA host or there could be intermediate connections through a radio or modem. An Ethernet port connection must be through an Ethernet switch with an appropriate Category 5 shielded patch cable.

2. Decide which communication protocol you will use. This could be DNP3 or

Modbus. See these documents for more information:

3. Provide the SCADA host with information about the various parameters it needs to extract from the application running in the RTU. Typically, the SCADA host software includes a utility that allows you to identify this information so it can be incorporated into the database at the SCADA host.

4. Using whatever human-machine interface (HMI) tools exist for the SCADA host, create graphical displays or reports that include the parameters from the application required for successful operator interaction (setpoints, flow variables and so on).

4.2.2 Communicating with a Laptop Using a Serial Port



Your laptop must have Field Tools software with FBxConnect software installed.



You must know a valid username/password combination for the RTU.

Upgrading System Firmware



To maintain hazardous location certifications, you can only replace components in the field with the exact same part so that the model string on the data plate remains correct. This means you cannot add any hardware not reflected in the model string or upgrade a hardware component to a newer version; any such upgrades are prohibited and void the hazardous location certification. This chapter describes the service tasks that everyone needs to know such as replacing batteries or installing a firmware upgrade. Any replacement not covered in this chapter can only be performed at an Emerson-authorized repair facility.

Important

Only use batteries supplied with the RTU or sold by Emerson Remote Automation Solutions as spare parts for this RTU. If you substitute a battery you obtain elsewhere you will void your hazardous location certification unless it is the identical part from the same manufacturer as that supplied with the RTU from Emerson.

Ensure the RTU is in a non-hazardous area. Never open the enclosure in a hazardous area.

EXPLOSION HAZARD: Do not disconnect equipment unless power has been removed or the area is known to be non-hazardous.

EXPLOSION HAZARD: Substitution of any components may impair suitability for Class I, Division 2.

EXPLOSION HAZARD: Batteries must only be changed in an area free of ignitable concentrations.

5.4 Removing/Replacing the SRAM Batteries

A 3V lithium coin cell battery in each of the two power supply modules provides backup power for the SRAM and the real time clock. These batteries operate continuously with a typical expected cumulative operation of 4900 hours if only one power module is installed, or 9800 hours if both power modules are installed.

A separate third lithium coin cell battery in the CPU module provides backup power for SRAM and the real time clock only when the CPU module is physically removed from the RTU, or if both power supply modules are physically removed from the RTU. The typical expected cumulative operation for this third backup battery is 1250 hours.

You do not need to power down the unit to replace the SRAM backup batteries.

Important

If the unit is ever powered down without the SRAM batteries installed, SRAM data is lost; this may include configuration data, alarms, events, and history. Always back up your data

before you remove the SRAM batteries if you know that main power will also be off.

Important

Replacement SRAM backup battery for the CPU module must be RENATA CR1632.

Important

Replacement SRAM backup batteries for the power module(s) must be one of the following:
