Introduction
The following start-up guide is designed to assist the user in the start up
of the XFCG4 (flow computer) or XRCG4 (remote controller) series. The
start-up guide, however, is primarily intended for gas orifice applications.
Using this guide in conjunction with other drawings and documentation
that accompany the user’s order should result in a smooth installation. If
there are additional questions that are not answered by this guide or
other provided documentation, the user needs to call their local Totalflow
representative or call the number listed on the back page of this guide.
If the user is familiar with the XSeries products, the XFCG4 will install in a
similar fashion. While the components on the circuit boards are different,
the pin outs, jumpers and connector placements are identical.
Installation and Start-Up Sequence
HINT: The following steps represent the recommended start-up
sequence. As a result, some of the steps do not go into great
detail either because detail is not needed or because more
information is available later in the guide. As such, the user is
encouraged to scan through the start-up guide before beginning
the installation.
Step 1 Physical Mounting and Piping
1A Unpack the equipment, and inspect for damage and missing or
incorrect components. The user will then need to ascertain
where to mount the unit.

3
1B Install the bracing for the unit (pipe saddle, direct mount or
pipe driven in the ground). Attach the U-bolts to the 2” pipe
using silicone spray or Teflon tape to prevent galling (see
Figure 1).

1D Mount the manifold to the bottom of the unit. The right port of
the unit is normally high pressure (upstream side). Check the
XIMV model number to verify that it is designed for flow from
left to right (4 CYC) or right to left (4 AYC). The user can look
on the transducer for (H or +) for high side and (L or -) for low
side. For direct mount manifolds, the direction is very
important. See Figure 3 for a typical manifold configuration.
1E Connect the stainless steel tubing from the manifold to the
orifice tap valves. With the manifold equalized to avoid
damaging the transducer, apply pressure to the manifold, and
check for leaks. For the best measurement, use large bore,

4
short, equal length gauge lines with a downward slope to the
taps (at least 1” per foot).
Figure 3. Typical Manifold Mount
Step 2 Installing and Wiring RTD and Probe
The RTD measures flowing gas temperature. Procedures presented in
this section enable the user to install the RTD into the meter run and wire
leads to the main electronics board. This procedure is for the XFCG4; the
XRCG4 does not have RTD inputs.
Totalflow
Supplied
Materials
•RTD Probe with 10’ of cable. Optional lengths: 15’,
25’, 30’, 40’ and 50’.
•One (1) Thermowell with ¾” NPT threads.
Optional threads are ½” and 1”.
•Nylon tie wraps
Customer
Materials
Supplied
•Customer must specify or provide Thermowell “U”
length.
•Teflon tape
2A Install the Thermowell into the meter run. Using snap ring
pliers, adjust the probe length so that it is spring loaded
against the bottom of the Thermowell (See Figure 4).
Figure 4. Typical RTD Installation
2B Remove one of the hole plugs, and install the cord connector.
Remove the nut, sealing ring and rubber grommet from the

5
cord connector. Slide the nut, sealing ring and grommet over
the RTD cable. Insert the cable through the body of the cord
connector. Allow enough cable to extend into the unit for
connecting wires to the RTD termination block. Secure the
cable with the grommet, sealing ring and nut.
NOTE: The charging source and power should be removed from the unit
before performing any field wiring.
2C Connect the RTD probe to the XFCG4’s RTD connector as
follows. Before making connections to the terminal block,
remove spade lugs, if attached, and trim the wire ends back
¼”. Remove the J7 terminal block from the XSeriesG4 main
electronic board. Loosen the terminal block securing screws,
insert the wire and then retighten (see Figure 5). Reinstall the
terminal block with the wires attached.
Figure 5. RTD Terminal Block Wiring
Step 3 Battery Installation
3A To extend the life of a battery pack, fully charge the battery
prior to installation. A system using solar panels may not fully
charge the battery. Also, a fast charge, which the solar panel
cannot provide, improves the life of the battery (See Tip
below).
3B Remove the unit’s battery cover plate, and insert the battery
pack (See Figure 6). Insert the battery pack with its long
dimension facing outward. When the cover is reinstalled, it will
fit snugly against some battery packs. The screws can be
loosened to accommodate large batteries.
Figure 6. Battery Compartment

6
3C Connect the battery pack connector to the main electronic
board battery connector J1 on the XFCG4 or J16 on the XRCG4.
This is located in the upper right corner of the board.
3D Observe the LCD. The display should power up displaying
Warm Start information and begin scrolling through the default
display items. If unit display does not display, see display topic
later in this guide.
CAUTION: NEVER connect the solar panel power cable to the unit
unless the main battery pack is connected.
TIP: To recharge a battery, a quick charge will remove the buildup in
the battery more effectively than a “trickle” charge. A battery slowly
drained by the low light conditions on a solar charged system or
setting in storage will be less likely to recover than a battery pack
that was quickly discharged from a short. Store batteries in a cool
environment for less drainage.
Step 4 Lithium Battery Connection
4A G4 units are shipped from the factory with the lithium
battery jumper in the Disabled position. Verify that the
Memory Backup is set to enabled with a jumper on the upper
two pins of J13 on the XFCG4 or J1 on the XRCG4. In Station
Setup, verify that the Lithium Battery Status is OK. If the status
is not OK, the lithium battery is below 2.5 volts and should be
replaced.
Step 5 Solar Panel Installation
Totalflow
Supplied
Materials
•One solar panel and cable
•Two U-bolts and fastening hardware
•One solar panel bracket
Customer
Materials
Supplied
•Cable ties
•One 9-inch or greater extension of 2-inch pipe
•One 2-inch collar
NOTE: Step 5A is not required if the pipe is tall enough without the
extension.
5A Attach the 2-inch pipe to the top end of the XFCG4 or XRCG4
mounting pipe. Securely tighten. Install a 2-inch pipe extension
into the collar, and securely tighten.
5B Install the solar panel on the mounting bracket with the
provided hardware. Attach the solar panel mounting plate to
the top end of the 2-inch pipe with U-bolts and associated

7
mounting hardware. Do not tighten U-bolts until the solar panel
has been correctly oriented.
5C If needed, connect the solar panel power cable to the solar
panel connector on the back of the unit. DO NOT connect the
other end of the cable to the unit until all steps are complete,
and the main battery pack has been connected.
5D Position the solar panel to face south in the northern
hemisphere and north in the southern hemisphere. Tighten the
U-bolts to avoid movement by wind or vibration. Check the
solar panel polarity using the digital voltmeter to insure (+) and
(-) wires are properly identified.
5E Remove one of the hole plugs from the side of the enclosure,
and install the cord connector.
Remove the nut, sealing ring and rubber grommet from the
cord connector. Slide the nut, sealing ring and grommet over
the cable, and insert the cable through the body of the cord
connector. Allow enough cable to extend into the unit for the
connection to the charger input +/- terminals located on the
main electronic board, XFCG4 terminal block J5 or XRCG4
terminal block J17 charger input terminals. Secure the solar
panel cable using the grommet, sealing ring and nut.
TIP: To prevent moisture from entering the unit, allow the cable to dip
below and then rise to the access hole. This will provide a path for
rainwater away from the access hole.
5F Connect solar panel wiring to main electronic board.

Step 6 XFC/XRC Setup
NOTE: Connecting to the G4 meters with PCCU32 will require version
7.05.5 or later.
6A Connect the laptop running PCCU32 to the unit via local serial,
USB or Ethernet. For more information on making a local
connecting to the flow computer, see PCCU32 Connectivity
later in this guide.
6B Set the date/time, ID, location and AGA setup using the Entry
mode in PCCU32.
6C In Calibration mode, verify the registers for static pressure,
differential pressure and temperature. After completing this
task, select RTD Installed, uncheck Use Fixed TF and adjust
RTD Bias if a temperature standard is used. Perform as found
calibration checks.
6D If calibration is needed, calibrate the static pressure first and
then differential pressure using a deadweight tester or
acceptable standard. Insure that both orifice taps are closed
and bypass valves are open during the AP calibration to avoid
a false DP. Make sure there are no leaks in the manifold or
test equipment. Perform as left calibration checks, as needed.
6E Place the unit online. To avoid inducing toggle and/or a
calibration shift, close the vent valve, open the bypass valve
and then open the orifice tap valves slowly (high pressure side
first). Once both orifice tap valves are fully opened, the bypass
valves can be closed.
6F Verify that the unit is calculating volume correctly. Watch the
display or look at the Current Values in Entry mode of
PCCU32. Collect data, and review the event and characteristic
files to insure all parameters are set properly.
6G Optional – When the user has verified that all setup and
calibration is complete and the unit is online calculating
volume, it is recommended that a Reset Volume command be
sent using PCCU. This allows the unit to have what might be
considered an official starting point for good live data. The
Reset Volume will be recorded in the Events file to mark the
date and time.

PCCU32 Connectivity
RS-232 Local Connect
The RS-232 local connection requires a serial port on the host computer
(generally a laptop). A PCCU cable is required to connect the host
computer to the flow meter’s round military connector. Connecting the
PCCU cable to the flow meter will cause an annunciator in the LCD to
display an upper case letter “L” for local connect. To connect PCCU32 to
the meter, click the Connect to Totalflow icon on the toolbar. To connect
and move directly to Entry mode, click on Entry instead of the Connect
icon.
If the meter has been given a security code, the user needs to ensure
that they have entered that code in the PCCU32 System Setup screen.
The factory default for a security code is 0000. Cold starting the meter
re-establishes the 0000 security code; however, cold starting the meter
also deletes historical data.
USB Connectivity
Note: USB connectivity requires PCCU32 version 7.17 or higher.
The first time that the user connects their laptop to a G4 meter using the
USB connectivity, the appropriate drivers need to be installed.
AConnect the G4 meter (XFC/XRC) to the laptop. After a couple
of seconds the “Found New Hardware Wizard” will appear. It
will ask if, “Windows should connect to Windows Update and
search for software?”
Select “No, not this time” and click “Next” to continue.
BThe next dialogue box will ask, “What do you want the wizard
to do?”
Select “Install the software automatically (Recommended)” and
click “Next” to continue.
CAt this point you will get a Microsoft® message warning that
the Totalflow USB driver has “not passed Windows Logo
testing”. If you want to use your laptop’s USB port you will
need to click on “Continue Anyway” and proceed with the
installation.
DThe “Found New Hardware Wizard” has finished. Click
“Finish”. The Totalflow USB driver is now installed.
NOTES: The above procedure creates a virtual com port on the laptop.
The com port disappears when the meter is disconnected.
The com port can be seen to appear and disappear in the
Device Manager whenever the USB cable is connected or
disconnected from the laptop.

12
The user does not need to go through the installation again. If
the user sees the Wizard initiate on subsequent connects to
their meter, click the Cancel button. If connecting to a
different USB port on their laptop, the user needs to go
through the same procedure.
Ethernet Connectivity
ABB Totalflow now supports TCP APIPA functionality. Automatic Private
Internet Protocol Addressing (APIPA) is a common alternative to the user
of the Dynamic Host Configuration Protocol (DHCP) to request and
retrieve an Internet Protocol (IP) address for a host. A Windows-based
computer that is configured to use DHCP can automatically assign itself
an IP address if a DHCP server is not available. For example, this can
occur on a network without a DHCP server or if that server is down for
maintenance.
With the addition of this feature, a computer can assign itself an IP
address in the event that a DHCP server is not available or does not
exist on the network. The feature has been implemented to make
configuring and supporting a Local Area Network (LAN) running TCP/IP
less difficult. After the network adapter has been assigned an IP address,
the computer can use TCP/IP to communicate with any other computer
that is connected to the same LAN and that is also configured for APIPA
or has the IP address manually set to 169.254.x.y (where the x and y are
the client’s unique identifier) address range with a subnet mask of
255.255.0. Additionally, the DNS Server is set to 0.0.0.0, and the Default
Gateway is 0.0.0.0.
AConnect locally to the meter using either RS-232 or USB.
Move into Entry mode within the PCCU application. Select
Communications from the tree-view and then the Network tab.
Within the screen, enter in the network ID, set the Enable
DHCP to Yes and then fill in the remaining fields, as
necessary. Click the Send button.
BSelect Totalflow/TCP from the tree-view. On the Setup screen,
select Totalflow/TCP as the communication protocol. Click
Send.
CClick the Setup icon on the PCCU toolbar. The System Setup
dialog box displays. In the PCCU Com Port drop-down menu,
select Network. Enter in the network ID or IP for the meter that
was established earlier in the meter setup. Click the Close
button. Connect the Ethernet cable between the laptop and the
G4. Press the Reset button on the G4.
NOTE: The user will need to allow for the local area connection to stop
acquiring the network. The progress can be tracked by clicking
the Windows Start button > Settings > Network Connections >
Local Area Connection. Upon completion, continue to step D.

13
DExit PCCU, and reconnect.
Figure 10. Network Tab
Alternate Ethernet Connectivity–Adding a 2nd Ethernet Port to a
Laptop
A second Ethernet connection is easily installed on the laptop using a
USB to Ethernet adaptor (Totalflow recommends TRENDnet USB to
10/100Mbps Adaptor, Part No. TU2-ET100). This configuration allows
the user to keep their current laptop network settings for home or office
networking.
AInsert the USB to Ethernet adaptor in an available USB slot.
Install the software/drivers per adaptor manufacturers’
instructions. Windows generates an IP address for the
Ethernet adaptor using APIPA. Connect to the flow computer
via a crossover cable (or adaptor), and reboot the laptop.
APIPA will assign the laptop an IP address between
169.254.0.1 and 169.254.255.254 (the actual address is not
important).
BGo to the folder where PCCU is installed. Create a
PCCU32.exe shortcut, and drag to the desktop. Right-click the
shortcut, and move to Properties. Under the Shortcut tab, set
the Target to C:\PCCU32\pccu32.exe TCP:169.254.0.11, and
click Apply. Under the General tab, the user can then give the
shortcut a recognizable name (i.e., CrossoverCablePCCU).
Communications
Most wiring diagrams, including communications are available on the
web at http://www.abb.com/totalflow. Communication pin-outs of the
XFCG4 and XRCG4 are shown on pages 8 and 9 of this guide.
The following discussion deals primarily with the unit communicating with
the Host (typically WinCCU).

14
To communicate with the Host, the XFCG4 or XRCG4 has remote
communication’s ports that can function as RS232, RS485 or RS422.
Depending on the customer’s order, most units are shipped with the
appropriate wiring in place for the specified communication’s equipment.
After installation of the unit and with the communications path complete,
the user needs to enter the appropriate communication’s parameters.
The unit was most likely shipped with Comm 1 set up for Totalflow
Remote protocol. If not, select the Protocol using the Entry mode and TF
Remote setup (see Figure 11) of PCCU32. The protocol must be
selected first for the appropriate communications parameters to be
displayed. A blinking telephone pole symbol " " in annunciator position
A8 (default) indicates Comm 1 port is active.
The data bits, stop bits and all required communications parameters can
be modified with PCCU32. Units will typically be shipped with correct
default comm port settings but may need fine tuning for optimum
operation.
Warning: As opposed to the XRCG4, the XFCG4 has only one Switched
V-Batt/Operate line; if it is needed, Enable it only on one
Comm Port even though both ports may require its use. The
V-Batt/Operate line will switch on/off at the Listen Cycle
timing of the port that enabled it.
Figure 11. PCCU32 Remote Communication Setup
Communications Troubleshooting
A new radio or modem system that doesn’t communicate is difficult to
troubleshoot because proper operation has never been proven, and all
the initial hardware and software settings are suspect. More than one
problem can be present, causing component replacement to be an
inadequate troubleshooting technique. Use the following checklist as an
aid.

15
•Does the " " flash (Totalflow Remote Protocol only) in the A8
annunciator position on the display (default position)? If no,
1) The Protocol needs to be selected in the Entry Mode using
PCCU32.
2) The communication’s module in Comm 1 or Comm 2 is missing or
bad or the module is the wrong type (RS232 or RS485).
Note: Comm 1 and Comm 2 are in opposite locations when compared
to older electronics boards (2015333) generation 2 and older.
3) Inadequate 12 VDC battery voltage.
•Insure base radio is working for other locations.
•Verify Station ID and Device ID matches with WinCCU and is the
only Totalflow device with that ID.
•Verify Baud rate, Stop Bits, Security Code, and Link Establishment
time are same as CCU.
•Verify WinCCU is using Packet Protocol. XSeriesG4 devices support
only DB2 Packet Protocol.
•Verify wiring to antenna, to UCI, UCI to Radio for RS485 installation
or to Radio/Modem for RS232 installation.
TIP: To check for wiring shorts or opens with two or more wire
connections, use a multimeter set on continuity (resistance). Check
two wires at a time from one unit to another. If black and white
wires are to be tested, disconnect both wires at both ends, set one
probe on black, the other on white. The meter should read OL or
OFL (over range) if no shorts. Jumper the two wires at the other
end. The meter should read a low resistance if no opens. This
method requires only one end of wiring to be tested, no matter how
far the units are apart.
•If a radio is used, verify directional antenna with correct
frequency range is pointed toward base (±6°). The antenna
should be mounted vertically, with the vanes perpendicular to
the ground. Verify radio is good, with the same frequencies
used.
•If a modem is used, verify dial tone on line at the telephone
company’s termination box by checking Tip and Ring. Check
wiring from phone company’s box to dial-up modem. If cellular,
also check for proper Tip & Ring voltage. Insure that the phone
number is correct in the unit and WinCCU.
NOTE: Telephone companies in the United States typically use a 48 volt
power supply so the on-hook voltage between the Tip and Ring
wires should be something less than 48 volts. Measuring another
way, Tip to ground is approx. zero volts and Ring to ground is
approx. –48 volts.

16
In the off-hook condition; Tip to ground will be approx. –20 volts
while Ring to ground will be approx. –28 volts or approx. 8 volts
between Tip and Ring. Users in other countries will need to
consult with their local telephone company.
Standard Display
Items that appear on the unit’s display are programmable by the user,
however based on the measurement application; units will be shipped
with some default display items. Table 1 is a typical set of default
displays for an AGA-3 application. Engineering units may vary from
those shown if the unit supports the “Selectable Units” feature.

Visual Alarm & Status Codes
After the unit completes recording of Log Period flow and operational
records, the LCD will show any alarm conditions that have occurred.
Also, the date, hour and type of alarm conditions are stored in the
device’s memory. Status codes are also displayed when the conditions
exist. An alarm or status code can be a character, letter or symbol. The
alarm and status codes shown in Table 2 will appear on the right side of
the LCD screen (see Figure 12).

The Display Does Not Scroll As Expected
When power is first applied, the unit should quickly go through startup
and begin cycling through the pre-programmed display items. If the
display does not scroll after startup, disconnect the main power and then
re-connect it. You should see something similar to:
Totalflow 32 Bit XFC
OS Part No. 2102900-001
If the display still doesn’t scroll, try disconnecting the power and re-
connecting it again. If still no success, do the following:
With PCCU32, connect to the unit and establish communications such as
Connect To Totalflow, Entry Mode, etc. Go into Terminal Mode and type
“0.0.0=COLD” (Do not enter quotes). The unit should go through a Cold
Start procedure and begin scrolling. If this does not succeed, call the
number on the back of this guide and talk to a customer service
representative.
