Introduction The Model XGS868 flow transmitter must be properly installed and

programmed, as described in the Startup Guide, before it can provide
accurate flow rate measurements. After completing the installation
and initial setup, use this chapter to program the advanced features of
the Model XGS868’s User Program.

Step-by-step programming instructions are presented in this chapter.
Also, as a programming aid, a complete set of menu maps for the SITE
EDIT MENU are included in Appendix A, Menu Maps for IDM. The
specific figure numbers will be referenced throughout this chapter, as
required.

Refer to the appropriate section for a discussion of the following SITE
EDIT MENU features.

• Channelx-Status - activate one or both channels and select the

desired measurement method.

• Channelx-System - enter the individual channel parameters.

• Channelx-Pipe Parameters - enter the pipe geometry and other

parameters.

• Channelx-Input/Output - set up the inputs and outputs.

• Channelx-Setup - set the signal limits, response times and mass

flow status.

• Global-System - select system units (English and metrics).

• Global-Input/Output - set up error handling, option cards and

display.

• Global-Comm Port - set the serial port parameters.

Note: The “x” in CHx represents the channel number. If you are

using a 1-Channel meter, only Channel 1will appear.

To get the XGS868 up and running as quickly as possible you must,
as a minimum, activate the channel(s), enter channel and global
system data and pipe parameters. The Procedure Options sections at
the end of each menu will help you in programming the required
(quick startup) and optional data.

Note: In this manual, only the programming of Channel 1 will be

described. T o pr ogram Channel 2 of a 2-channel meter , simply
repeat the same procedure presented for Channel 1.

Programming Methods There are three methods for programming the XGS868 flowmeter:

• Instrument Data Manager (IDM) - a PC-based, non-resident

software program that communicates with the XGS868 via its
RS232 serial port.

• PanaView™ - a Windows-based, non-resident software program

that communicates with the XGM868 via its RS232 serial port.

• Remote Control Communications Unit (RCCU) - a hand-held

device that communicates with the XGM868 through wireless,
infrared transmissions.

Note: The XGM868 cannot be programmed at the electronics

enclosure. One of the above methods must be used.

Although the actual displays differ somewhat, the general procedures
are the same for all three programming methods. This chapter
provides detailed IDM programming instructions. If you are using
PanaView™, see Appendix D, PanaView™ for IDM-Compatible
Meters and/or the PanaView™ User’s Manual (910-211) for detailed
instructions. If you are using the RCCU, refer to Appendix C, Remote
Control Communications Unit, for specific instructions.

Note: This manual is for instruments using software verion Y3DS or

later.

Activating a Channel The Channelx-Status submenu permits selection of the desired

measurement method. In addition, it is used to activate/deactivate one
or both of the channels in a 2-Channel Model XGS868.

While following the programming instructions, refer to Figure A-1 in
Appendix A.

To access the Channelx-Status submenu:

1. Open the SITE EDIT MENU from the Edit Functions menu.

2. Select Channelx.

3. Select Status.

4. Select Burst to activate the channel/path and press Next Item/

Enter.

Note: Burst is automatically selected for a 1-Channel meter.

5. Use the pull-down menu to select one of the measurement

methods described below and press Next Item/Enter.

• 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

Signal submenu section on page 1-15 of this chapter.

the

Procedure Options After completing the above step, IDM returns to the Channel

PROGRAM window. Do one of the following:

• To continue entering “quick startup” data, proceed to Step 3 in

the following section.

• To continue regular programming, refer to Appendix A, Menu

Maps, to navigate to the desired menu.

• To leave the User Program, press Exit Page twice.

An offset between the upstream and downstream transit

At this prompt, specify a time measurement offset that
compensates for a shift resulting from cross-correlation.

The percentage of peak used to calculate the transit times
and Delta T is specified at this prompt.

Both the upstream and downstream transducers transmit
ultrasonic pulses in bursts, which consist of a series of

8

transmit pulses. XMIT SAMPLE SIZE determines how many
bursts are sent in one direction before sending in the other
direction.

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 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.

The Divisor used to calculate the Measure Mode
integrated threshold level 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.

Adjusting LCD Contrast and Brightness

Both the contrast and the brightness of the optional LCD may be
adjusted to suit individual needs. As shown in the upper right view of
Figure 4-1 on page 4-12 of the Service Manual, there are two 3/4-turn
adjustment potentiometers located on the LCD circuit board. Using
these pots for the LCD adjustment, complete the following steps:

!WARNING!

Never remove the covers from the XGS868 in a hazardous

environment while the line power is on.

1. Make sure the XGS868 is in a safe environment, and loosen the

set screw to remove the front cover (see Chapter 4, Parts
Replacement, in the Service Manual for details, if necessary).

IMPORTANT: If the XGS868 is to be installed in a hazardous

environment, adjust the LCD brightness and contrast
in a safe area, before mounting the enclosure.

2. With power still applied to the meter, carefully use a small
screwdriver to adjust the LCD brightness. Turning the

BKLT

(backlight) pot fully clockwise yields maximum brightness.

3. In a similar manner, adjust the
contrast as desired. At either extreme of the

CONT (contrast) pot to set the LCD

CONT pot, the display

is unreadable; turn the pot fully counterclockwise and then turn it
clockwise very slowly until the display is clear.

4. Readjust the

BKLT control, as desired.

5. Replace the front cover on the XGS868, and secure it in place with
the set screw.

The meter may now be placed back into service.

XGS868 must be linked to the computer terminal with the optional
Instrument Data Manager (IDM) software.

Note: See Chapter 1, Installation, of the Startup Guide for

instructions on wiring the RS232 serial port. For more
information on serial communications refer to your EIA-RS

Serial Communications manual (916-054).

After making the hardware connections and installing the IDM
software, the following data may be output to a printer connected to
the personal computer:

• live data in numeric or graphical format

• log file in numeric or graphical format

• site file in tabular format

• transducer signal array data in tabular format

Introduction In order to log data to the Model XGS868 it must be fitted with an

optional data logging option card in Slot 2. See Chapter 4, Parts
Replacement, of the Service Manual for instructions on installing the

card. After the option card has been installed, further memory
expansion is possible by plugging an industry-standard PCMCIA
memory card into a connector on the data logging option card.

If you do not have the data logging option card, you can log data on a
remote computer terminal via the meter’s RS232 serial port. This
requires the use of the optional Instrument Data Manager (IDM)
software. Refer to the IDM User’s Manual in the chapter discussing
the Real Time Menu.

This chapter explains how to log data to the Model XGS868’s using
the optional data logging card and IDM. Also refer Appendix A,
Menu Maps.

Note: After the specified data has been logged, the log file may be

uploaded to the Remote Control Communications Unit
(RCCU) via an infrared transmission. See Appendix C,
Remote Control Communications Unit.

Setting Up a Standard Log

Using the RCCU (cont.) To energize the RCCU, press the [ON] key on its keypad. The

RCCU’s LCD display, which consists of 4 lines x 20 characters, will
be activated. See Figure C-2 on page C-2 for the layout of the RCCU
keypad and display.

For reliable RCCU communications, the infrared receiver in the
window of the XGS868 should have a clear line of sight to the RCCU
and should be located within 8 ft (2.5 m) of the RCCU with an angle
of incidence of no more than 15°.

Immediately upon activation, the RCCU will perform its normal
startup routine. This results in a display of the GE Panametrics logo,
followed by these informational displays:

Communications Failure If an attempt to communicate with the XGS868 does not result in a

proper connection with the RCCU, an error message such as the
following appears:

8C or Communicating
NO Packet Rcvd ce2
Retry/Abort Commlink

RETRY ABORT

F1 F2 F3

At this display, press [F1] to
try again or press [F2] to quit.

Make sure that the RCCU battery is not weak, the windows on both
the RCCU and the XGS868 are clean, the transmission distance does
not exceed 8 ft (2.5 m), the angle of incidence does not exceed 15°
and there is an unobstructed line of sight between the two devices.
Then, carefully aim the RCCU and try again. If this fails to resolve
the problem, see Replacing the RCCU Battery on page C-14 for
instructions on RCCU battery replacement. If a fresh battery does not
solve the problem, contact GE Panametrics for help.

The User Program Use the RCCU keypad (see Table C-4 on page C-3) to navigate

through the PROG menu of the User Program. The menu map may be
followed in sequence, or the [↑] and [↓] keys may be used to scroll
through the prompt screens. The [←] key may be used to delete the
last alphanumeric character that was entered from the keypad.

Note: Be sure to record all the programming data entered in this

chapter in Appendix B, Data Records.

Programming of the CHx-ACTIV, CHx-SYSTM, CHx-PIPE, and
GLOBL-SYSTM submenus is required for basic operation of the

Model XGS868. Failure to accurately enter all of the necessary
information will result in unreliable flow rate data. Therefore, be sure
to complete at least the sections of this chapter pertaining to those
three submenus. Refer to Figures C-7 through C-12 on pages C-16
through C-21.

Except for the three submenus noted above, it is not necessary to
program the Model XGS868 flowmeter in any particular order.

C-6 Remote Control Communications Unit

November 2004

Accessing the User Program

To access the XGS868’s User Program, the RCCU must be pointed
directly at the receiver in the window on the electronics enclosure
whenever data is being sent or received (see Figure C-3 below).

Optional Display

Receiver

Green Power LightRed Fault Light

Figure C-3: XGS868 Front Window

The green light in the window glows continuously to indicate that the
XGS868 is receiving power, while the red light should glow for more
than two seconds whenever a signal from the RCCU is initiated. If the
red light blinks repeatedly, the XGS868 is not

receiving the RCCU
signal correctly. The Send/Receive lights on the RCCU blink once to
indicate the sending/receiving of a signal.
