Environmental Compliance Waste Electrical and Electronic Equipment (WEEE) Directive Panametrics is an active participant in Europe’s Waste Electrical and Electronic Equipment (WEEE) take-back initiative, directive 2012/19/EU. The equipment that you bought has required the extraction and use of natural resources for its production. It may contain hazardous substances that could impact health and the environment.
To ensure safe and reliable operation of the Model XGS868i Ultrasonic Flow Transmitter, the system must be installed in accordance with the guidelines established by Panametrics engineers. Those guidelines, which are explained in detail in this chapter, include the following specific topics: •...
Chapter 1. Installation Site Considerations Because the relative location of the flowcell and the electronics enclosure is important, use the guidelines in this section to plan the XGS868i installation. Figure 1 shows a typical XGS868i enclosure and spoolpiece ready for insertion into a process line.
Note: When using non-Panametrics cables to connect the flow rate transducers to the Model XGS868i electronics enclosure, the cables must have electrical characteristics identical to the Panametrics cables. Type RG62 a/u coaxial cable should be used, and each cable must be the same length (within ±4 in.).
Figure 1 on page 2 shows a typical Model XGS868i spoolpiece, with a mounting bracket to hold the electronics enclosure. For detailed instructions on installing the transducers and/or spoolpiece, refer to the supplied drawings and the enclosed Panametrics Gas Transducer Installation Guide (916-049). Installing Temperature and Pressure Transmitters Optional temperature and pressure transmitters may be installed near the ultrasonic transducer ports as part of the flowcell.
Chapter 1. Installation Mounting the XGS868i Electronics Enclosure The standard Model XGS868i electronics package is housed in a Type-4X weather-resistant enclosure suitable for indoor or outdoor use. Refer to Figure 8 on page 21 for the mounting dimensions and the weight of this enclosure. The Model XGS868i electronics enclosure is fitted with a mounting boss that has a single 3/4”...

Chapter 1. Installation Making the Electrical Connections (cont.) WARNING! Always disconnect the line power from the Model XGS868i before removing either the front cover or the rear cover. This is especially important in a hazardous environment. Disconnect any existing power line from its source. Loosen the set screw on the rear cover.
Chapter 1. Installation 1.7.1 Wiring the Line Power The Model XGS868i may be ordered for operation with power inputs of 100-120 VAC, 220-240 VAC, or 12-28 VDC. The label on the side of the electronics enclosure lists the meter’s required line voltage and power rating. The fuse size is listed in Chapter 4, Specifications .
Chapter 1. Installation 1.7.2 Wiring the Transducers Before wiring the XGS868i transducers, complete the following steps: • disconnect the main power from the electronics enclosure • remove the rear cover and install all required cable clamps Based on the location of the electronics enclosure, proceed to the appropriate sub-section for detailed instructions. 1.7.2.1 Flowcell-Mounted Enclosure For an electronics enclosure mounted directly on the flowcell, wire the transducers as follows:...
Page 17
Chapter 1. Installation 1.7.2.2 Remote-Mounted Enclosure For a remote mounted enclosure, refer to the wiring diagram in Figure 10 on page 23 and the remote transducer wiring in Figure 12 on page 25, and complete the following steps: WARNING! Before connecting the transducers, take them to a safe area and discharge any static buildup by shorting the center conductor of the transducer cables to the metal shield on the cable connector.
Chapter 1. Installation 1.7.3 Wiring Std 0/4-20 mA Analog Outputs The standard configuration of the Model XGS868i flow transmitter includes two isolated 0/4-20 mA analog outputs (designated as outputs 1 and 2). Connections to these outputs may be made with standard twisted-pair wiring, but the current loop impedance for these circuits must not exceed 600 ohms.
Page 19
Use the serial port to connect the Model XGS868i flow transmitter to a printer, an ANSI terminal or a personal computer. The RS232 interface is wired as Data Terminal Equipment (DTE). Table 1 lists the standard cables available from the factory for this purpose. Table 1: Panametrics Serial Cables Part Number PC Connector...
Page 20
Chapter 1. Installation 1.7.4.2 Wiring the RS485 Interface Use the optional RS485 serial port to network multiple XGS868i flow transmitters to a single control system. As an option, the standard RS232 port on the XGS868i may be configured as a two-wire, half-duplex RS485 interface. IMPORTANT: The Model XGS868i must be configured at the factory for RS485 operation.
Chapter 1. Installation 1.7.5 Wiring the Option Cards The Model XGS868i can accommodate one option card in Slot 1 and one option card in Slot 2. The following option card functions are available only in the combinations listed in Table 14 on page 59: •...
Page 22
Chapter 1. Installation 1.7.5.2 Wiring an Alarms Option Card Each alarms option card includes two or four general-purpose Form C relays (designated as A, B, C and D). The maximum electrical ratings for the relays are listed in Chapter 4, Specifications . Each of the alarm relays can be wired as either Normally Open (NO) or Normally Closed (NC).
Page 23
Chapter 1. Installation 1.7.5.3 Wiring a 0/4-20 mA Analog Inputs Option Card To calculate the standard flow rates, the Model XGS868i requires accurate temperature and pressure data from the measurement site. Transmitters installed in the flowcell can provide this information via an optional 0/4-20 mA analog inputs option card.
Page 24
Chapter 1. Installation 1.7.5.3 Wiring a 0/4-20 mA Analog Inputs Option Card (cont.) Before making any connections, complete the steps in Preparing for Wiring on page 13. Wire the analog inputs as shown on the label in the rear cover (see Figure 11 on page 24). The analog inputs option card can be calibrated with the Model XGS868i’s built-in analog outputs.
Page 25
Chapter 1. Installation 1.7.5.5 Wiring an RTD Inputs Option Card The Model XGS868i RTD (Resistance Temperature Device) inputs option card provides two or four direct RTD inputs (designated as A, B, C and D). Each RTD input requires three wires, and should be connected as shown on the label in the rear cover (see Figure 3 on page 6 and Figure 11 on page 24).
Page 26
Slot 2. The RS485 standard allows up to 32 nodes (drivers and receivers) on one multidrop network, at distances up to 4,000 ft (1,200 m). Panametrics recommends using 24-gauge (24 AWG) twisted-pair wire with a characteristic impedance of 120 ohms and 120-ohm termination at each end of the communications line.
Page 27
Chapter 1. Installation 1.7.5.9 Wiring the MODBUS/TCP Interface Customers can also use a modified XGS868i that provides a MODBUS/TCP interface to communicate to an internal network. An optional MODBUS/TCP card with a unique MAC (IP) address (installed only in slot 2) includes an RJ45 connector.
Page 28
Chapter 1. Installation 1.7.5.11 Wiring the Foundation Fieldbus Interface To connect the Foundation Fieldbus interface to the XGS868i, make the network connections at J8, pins 1 and 2, as shown in drawing Y of Figure 13 on page 26. As an option, you can connect a shield to J8 pin 3, depending on the network wiring.
