Environmental Compliance

Waste Electrical and Electronic Equipment (WEEE) Directive

GE Measurement & Control 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.

In order to avoid the dissemination of those substances in our environment and to diminish the pressure on the natural resources, we encourage you to use the appropriate take-back systems. Those systems will reuse or recycle most of the materials of your end life equipment in a sound way.

The crossed-out wheeled bin symbol invites you to use those systems.

If you need more information on the collection, reuse and recycling systems, please contact your local or regional waste administration.

DigitalFlow™ XGM868i Programming Manual 1

Chapter 1. Programming Site Data

1.2 Programming Methods

You can program the XGM868i via either the keypad on the lower part of the glass enclosure, or PanaView™, a

PC-based, non-resident software program that communicates with the XGM868i via its RS232 serial port. PanaView supplements basic XGM868i functions with several additional capabilities. With PanaView, you can:

load and save site file data

create and save graph and log files

display text output and graphs of live measurement data

create custom templates for displaying text, graph and log data

interface with multiple GE instruments.

Although the actual displays differ somewhat, the general procedures are the same for all three programming methods.

This chapter provides detailed programming instructions for use with the keypad. If you are using PanaView™, see

Appendix C, Programming the XGM868i via PanaView™, and/or the PanaView™ User’s Manual (910-211) for detailed instructions.

IMPORTANT:

This manual is for instruments using software version Y4AM or later.

1.3 The XGM868i Enclosure Keypad

Keypad Program

Along with the 2-line, 16-character LCD, the XGM868i includes a 6-key magnetic keypad. The decal cutout for each key contains a hall effect sensor, pushbutton switch and visible red LED. The magnetic wand used to activate a magnetic key is found attached to the meter chassis below the front panel. An operator activates the key by pressing the magnetic wand up to the glass lid over the desired key. The LED will light indicating a successful key press.

Note: The pushbutton switch will also act as a key press but is done with the glass lid open. Do not use the pushbutton switch in a hazardous area where the lid needs to be installed.

Use the magnetic keypad to navigate through the user program. The menu map may be followed in sequence, or the four arrow keys may be used to scroll through the prompt screens. Figure 1 shows the front of the XGM868i, with magnetic keypad and magnetic wand.

Skan to Measure Mode when Delta T is less than the M>S_Switch value.

DO NOT change this value unless advised to do so by the factory.

The number of shifts corresponds to the actual number of transmits per cycle (number of signals added together in one direction to produce an averaged signal for one interrogation of the fluid) and need only be changed if the environment is very noisy or the acoustic signal is weak.

A Divisor is used to calculate the Measure Mode integrated threshold level and is not normally changed.

# Transmit Pulses specifies the number of pulses in a burst. For difficult conditions (i.e. long paths, high velocity or high temperature), settings as high as 16 may be necessary.

The XGM868i calculates the size of the transmit window based on pipe size and fluid sound speed. However, for diagnostic purposes, the window size may be reset.

The XGM868i calculates the size of the receive window based on pipe size and fluid soundspeed. However, for diagnostic purposes, the window size may be reset.

1.9.3 Configuring the Communications Port

The Model XGM868i flowmeter is equipped with an RS232 or an RS485 serial interface. An RS485 option is also available with MODBUS capability. When the MODBUS option is installed, the XGM868i may still also have the standard RS232 serial interface.

The meter can be configured with a MODBUS option card for MODBUS communications, a Foundation Fieldbus option card for Foundation Fieldbus communications, an Ethernet option card for Ethernet communications, or with a

MODBUS/TCP option card for MODBUS communication over the Ethernet, if desired.

Note: To set Fieldbus communications parameters, see Appendix E, Foundation Fieldbus Communications.

The serial port is used to transmit stored data and displayed readings to a personal computer by connecting the meter’s serial interface to the serial port of the PC. In addition, the Model XGM868i can receive and execute remote commands, using PanaView software via this link.

Use the

COMM submenu to set the communications port and MODBUS parameters. While programming the meter,

refer to Figure 30 on page 79.

1.9.3b Setting Up MODBUS Communications

When equipped with an optional MODBUS output card, the XGM868i can transmit flow data serially to a flow computer, or SCADA, using a Gould-type RTU protocol. Thus only the MODBUS function command, 3 (read multiple registers), 6 (write multiple registers) is valid. The XGM868i uses the following format for the data exchange:

The Send command (initiated by the host flow computer or controller) comes in the form:

[time delimiter]<Addr><3><First Register MSB>

<First Register LSB> <Register Count MSB>

<Register Count LSB><CRC Low><CRC High>[time delimiter]

The Response (initiated by the host flow computer or controller) comes in the form:

[time delimiter]<Addr><3><Byte count><Data...........>

<CRC Low><CRC High>[time delimiter]

The format for the returned data types is:

Integer (16 bit Integer) <MSB><LSB>

1 Register - 16 bit integer

Integer (32 bit IntegerI) <MSB><LSB><LSB><LSB>

2 Register - 32 bit integer

Floating Point (FP)<EXP><MAN><MAN><MAN>

2 Registers - 32 bit IEEE floating point number

Use the steps below to configure MODBUS communications:

IMPORTANT:

The XGM868i MODBUS communications settings chosen in the next four steps must match those of the

Skan Only is the preferred technique for locating the acoustic signal and for high velocity measurements. It is more robust in a noisy environment than the Measure technique.

Skan/Measure is the preferred technique to use for low velocity measurements.

If

Skan Only is selected at the above prompt, the meter uses this technique exclusively. However, if Skan/Measure is selected, the meter uses

Skan Only to find the acoustic signal and then tries to use the Skan/Measure technique for the actual measurement.

Note: To change the Skan Only and Skan/Measure parameters, see the

Signal

submenu section on page 14.

PanaView returns to the

Channel PROGRAM menu (see Figure 41 on page 95). Proceed to the System option.

Description

If the burst mode is set to Skan/Measure (S/M), the meter switches from Skan to Measure Mode when Delta T is less than the M>S_Switch value. DO NOT change this value unless advised to do so by the factory.

The number of shifts corresponds to the actual number of transmits per cycle (number of signals added together in one direction to produce an averaged signal for one interrogation of the fluid) and need only be changed if the environment is very noisy or the acoustic signal is weak.

A Divisor is used to calculate the Measure Mode integrated threshold level and is not normally changed.

# Transmit Pulses specifies the number of pulses in a burst. For difficult conditions (i.e. long paths, high velocity or high temperature), settings as high as 16 may be necessary.

The XGM868i calculates the size of the transmit window based on pipe size and fluid sound speed. However, for diagnostic purposes, the window size may be reset.

C.6.3c Activating Security in the Global Menu

In order to prevent unauthorized tampering with the flowmeter’s programming, the XGM868i is equipped with a security feature that locks all the keys except [PROG] (which, when pressed, requires the password).

When the system is locked, access to the menus will be denied unless the correct password is entered. The XGM868i is shipped with a default password (2719 and three spaces). For increased security, the default password should be changed.

E.1 Introduction

Foundation Fieldbus provides a means of communicating with the flowmeter. The patent numbers which apply are

5,909,363 and 6,424,872.

This Foundation Fieldbus device supports 6 Analog Input (AI) blocks, which can be configured to supply the following

measurements on the network (see Table 32).

*Metric or English units are determined by the setup of the flowmeter.

**Totalizer digits are available for informational purposes only. Respective totals are automatically scaled by the Tot Digits value selected in the flowmeter setup.

***If the meter is outputting Mole Weight, the unit is “mw”, otherwise it is the programmed pressure unit.

VOL_U, TOT_U, MASS_U, MTOT_U and PRESS_U are determined by the units chosen for these measurements in the flowmeter setup. See the instrument User's Manual for the setup of these parameters.

DigitalFlow™ XGM868i Programming Manual 141

Appendix E. Foundation Fieldbus Communications

E.2 Configuration Utility Setup

The following is an example setup using National Instruments Configuration Utility v3.1.

Figure 56 shows the Configuration Utility with a flowmeter on the network (GE Flow-XGM).

XGM

Figure 56: Configuration Utility Setup Example

Note: The following procedures assume that the device has been placed in the OOS (out-of-service) mode before executing.

E.3 Selecting the Desired Measurements

To set the measurement unit for each AI:

1. Double click on the

FLOW Transducer Block (in the tree under GEFlow-XGM).

2. Select the

Others tab and open the drop down list for the PRIMARY_SELECTOR and SECONDARY_SELECTOR (refer

to Figure 57 on page 143).

3. Choose the unit from the list (see Figure 57 on page 143).

142 DigitalFlow™ XGM868i Programming Manual

Appendix E. Foundation Fieldbus Communications

This unit will correspond to the unit that is available in the AI block for network connection. The PRIMARY_SELECTOR unit will correspond to

ANALOG_INPUT_1 and the SECONDARY_SELECTOR will correspond to ANALOG_INPUT_2.

4. After the desired measurements have been selected for the

PRIMARY and SECONDARY SELECTOR, choose the unit system ( UNIT_SELECTOR above the PRIMARY_SELECTOR) that was programmed in the flowmeter (English or SI).

Figure 57: Primary Selector Drop Down List

DigitalFlow™ XGM868i Programming Manual 143

Appendix E. Foundation Fieldbus Communications

E.4 Selecting Units for AI Blocks

To select the units for the individual AI blocks:

1. Double click on the AI block for which you wish to set the units (

ANALOG_INPUT_1 or ANALOG_INPUT_2 in the tree under

GEFlow-XGM; see Figure 56 on page 142).

2. Select the

Scaling tab and set the unit for the measurement based on the flowmeter settings.

For example, if the flowmeter was set to use the metric unit system and the

PRIMARY_SELECTOR was set to use

VELOCITY you would choose m/s for the unit as shown in Figure 58.

Warranty

Warranty

Each instrument manufactured by GE Sensing is warranted to be free from defects in material and workmanship.

Liability under this warranty is limited to restoring the instrument to normal operation or replacing the instrument, at the sole discretion of GE Sensing. Fuses and batteries are specifically excluded from any liability. This warranty is effective from the date of delivery to the original purchaser. If GE Sensing determines that the equipment was defective, the warranty period is:

one year from delivery for electronic or mechanical failures

one year from delivery for sensor shelf life

If GE Sensing determines that the equipment was damaged by misuse, improper installation, the use of unauthorized replacement parts, or operating conditions outside the guidelines specified by GE Sensing, the repairs are not covered under this warranty.

The warranties set forth herein are exclusive and are in lieu of all other warranties whether statutory, express or implied (including warranties or merchantability and fitness for a particular purpose, and warranties arising from course of dealing or usage or trade).

Return Policy

If a GE Sensing instrument malfunctions within the warranty period, the following procedure must be completed:

1. Notify GE Sensing, giving full details of the problem, and provide the model number and serial number of the instrument. If the nature of the problem indicates the need for factory service, GE Sensing will issue a RETURN

AUTHORIZATION NUMBER (RAN), and shipping instructions for the return of the instrument to a service center will be provided.

2. If GE Sensing instructs you to send your instrument to a service center, it must be shipped prepaid to the authorized repair station indicated in the shipping instructions.

3. Upon receipt, GE Sensing will evaluate the instrument to determine the cause of the malfunction.

Then, one of the following courses of action will then be taken:

If the damage is covered under the terms of the warranty, the instrument will be repaired at no cost to the owner and returned.

If GE Sensing determines that the damage is not covered under the terms of the warranty, or if the warranty has expired, an estimate for the cost of the repairs at standard rates will be provided. Upon receipt of the owner’s approval to proceed, the instrument will be repaired and returned.
