Introduction
This startup guide is to assist in the startup of the XFC6200EX flow
computer. It is hoped that this guide in conjunction with other drawings
and documentation that accompanies your order will result in a smooth
installation. If for some reason, you have questions that are not
answered in this guide or your other documentation, call your local
Totalflow representative or call the number listed on the back page of
this guide.
Installation & Start-Up Sequence
HINT: Step 1 thru 25 is a recommended start-up sequence and some of
the steps do not go into any great detail. Some steps because detail is
not required and some because more information is available later in the
Start-Up Guide. For example there are later topics such as installing the
RTD, batteries, solar panel etc. So, scan through the guide to see what
information is available before you begin the installation.
1. Unpack the XFC6200EX and 6270 OEU (Optional Equipment Unit) if
purchased. Inspect for damage and missing or incorrect
components.
2. Determine where to mount the 6200EX and OEU. Install the 6200EX
first and the OEU will be covered later. The 6200EX is rated for
Division 1, but the OEU must be installed in a Division 2 or General
Purpose area.
3. Install the support for the 6200EX (pipe saddle, direct mount,
standalone pipe, etc.). If mounting pipe to meter run, use a saddle
mount kit as shown in Fig. 1. Different size Saddle Mount kits are
available based on the meter run size. If mounting the 6200EX to a
pipe, use the 2-piece bracket Mtg. kit (Pt. # 210193) as shown in Fig.
2. Attach the side mount bracket to the 2” pipe with the two U-bolts
and then attach the 6200EX Mtg. bracket with available hardware.
The 6200EX can be on either side of the pipe depending on how the
side mount bracket is mounted (See Fig. 1). Use silicone spray or
Teflon tape to prevent galling of threads.
4. The method of mounting the 6200EX using the bracket mounting kit
depends on whether a discrete or block manifold is used. For
discrete manifolds, mount the 6200EX directly to the bracket as
shown in Figure 1 and then screw the tubing from the discrete
manifold into the bottom of the 6200EX’s transducer. If a block
manifold is used, sandwich the manifold between the 6200EX’s
transducer and the top of the bracket as shown in Figure 3. Block
manifolds as shown in Figure 3 can be mounted with four bolts
inserted up through the bottom of the bracket, through the manifold
and into the threaded holes of the 6200EX transducer. Larger block
manifolds with flanges on top and bottom will require separate
hardware to mount the manifold to the 6200EX’s transducer and then

3
mount the manifold to the mounting bracket. Do not forget to install
the o-ring flange seals in the recessed grooves on the block manifold
flange(s).
To verify direction of flow, look at the (+) and (-) signs on the
transducer tag. Plus(+) indicates high side (upstream) and (-)
indicates the low side (downstream), therefore flow is from (+) to (-).
If this causes the device to face the wrong direction, loosen the Allen
Head set screw on the neck of the device and with the hands turn
the unit clockwise until the unit is facing the correct direction. If the
unit gets tight before achieving the correct position, turn counter-
clockwise (no more than 360 degrees) until the correct position is
obtained; then re-tighten the set screw.

5. Connect stainless steel tubing from manifold to orifice tap valves. For
best measurement, use large bore, short, equal length gage lines
with a downward slope to taps (at least 1" per 3 feet). With the
manifold equalized to avoid damaging the device’s transducer, apply
pressure to the manifold and check for leaks.
6. Assemble and install the RTD using the instructions included with the
RTD kit. Wire RTD to unit per local codes. See page 7 for additional
information. See also Figures 6 & 9 for wiring terminations.
Installing the 6270 Optional Equipment Unit
The 6270 OEU (Optional Equipment Unit) contains the power supply,
battery and any optional communication’s equipment. If the user is
providing their own power and/or communications and not using the
Optional Equipment Unit go to Step 10.
The OEU can only be installed in a Division 2 or General Purpose
area. All wiring between the 6200EX which can be in a Div 1 area
and the OEU must be done per local codes. See pages 12 & 13 for
wiring terminations.
7. Mount the OEU on a 2” pipe or flat surface using the supplied
installation kit. If a solar panel is used and is to be pipe mounted, use
a pipe long enough or be able to add a coupling and pipe joint on top
of the existing pipe.
Figure 4 (6270 OEU Pipe or Panel Mount)

8. Assemble, mount, and run solar panel power cable down to 6270
OEU. If using an external AC power supply, run the DC output wiring
to the OEU. Remove one of the rubber plugs and using an approved
cord connector, run solar panel power cable or DC cable into OEU. If
using Totalflow’s external AC power Supply, it can be connected
directly to the side of the enclosure. Do not connect solar panel
wiring until all other wiring is complete. If using AC, the DC wiring
can be connected as long as the AC power remains off. See “Solar
Panel Installation” on page 9 for more information.
9. Run the appropriate conduit and wiring between the 6200EX and the
6270 OEU or customer supplied equipment. See pages 12 and 13
for terminations.
10. Verify all wiring is correct per drawings. If enclosed Wiring
Interconnect drawings (WIs) or User Drawings (UDs) conflict with
illustrations in this startup guide, the drawings should take
precedence. All wiring must meet local electrical codes.
11. If using the OEU, Mount and connect a fully charged battery to one
of the battery connectors or apply customer supplied power to the
6200EX.
12. The display on the 6200EX should go quickly through the startup
routine then start scrolling through the default display items. (If not,
see Tip on Page 22). This typically insures that the components and
power wiring are good. Refer to “Standard Displays" on page 18 for
typical default displays. Refer to “Visual Alarm & Status Codes" on
page 19 for location, symbols, and descriptions.
14. Connect FS/2 or laptop running PCCU32 to the unit. To use an FS/2,
the 6200EX must have been configured at the factory for FS/2
support. PCCU32 must have software Version 4.3 or higher and the
FS/2 must be 2018583-007 or higher.
15. Configure the 6200EX: Set date/time, ID, location, AGA setup, using
Entry Mode in PCCU32 or an FS/2.
16. If device supports multiple pressure ranges, select the correct Sp &
Dp range from the Range Select tab in Calibration Mode. (PCCU32)
17. In Calibration Mode, verify registers for Static pressure, Differential
pressure and Temperature. (PCCU32)
18. In Calibration Mode, assuming a temperature input device is used,
select TF Device Connected, un-check Use Fixed TF.
19. In Calibration Mode, perform (as found) calibration checks.
20. If calibration is needed or required by company policy, calibrate static
pressure first, then differential pressure, using a deadweight tester or
acceptable standard. Insure that both orifice taps are closed and
bypass valves are open during AP calibration to avoid a false DP.
Make sure there are no leaks in the manifold or test equipment.

7
21. Perform (as left) calibration checks.
22. Place Flow Computer on line: To avoid inducing toggle and/or a
calibration shift, close vent valve, open both bypass valves, then
open orifice tap valves SLOWLY (high pressure side first). Once
both orifice tap valves are fully opened, the bypass valves can be
closed.
23. Verify that the unit is calculating volume correctly. Watch the display
or look at the Current Values in the Entry Mode of PCCU32.
24. Collect data and review the event and characteristic files to insure all
parameters are set properly.
25. Optional: When you are reasonably sure that all setup and
calibration is complete and the unit is on line calculating volume, it is
recommended that a Reset Volume command be sent from the
PCCU32 Entry Mode. This allows the unit to have what might be
considered as an official starting point for good live data. The Reset
Volume will be recorded in the Events file to mark the date and time.
Note: This is the end of the startup sequence, individual topics follow.
Installing and Wiring RTD
If the 6200EX is installed in a Div 1 area, a Div 1 approved RTD
assembly must be used. RTD kits are available from ABB Totalflow. If
the customer orders the RTD kit but provides their own thermowell, the
U-length must be provided. Various sizes of thermowells are available
from Totalflow, but the U-length or insertion depth will be required.
The following procedure assumes a Totalflow kit was provided.
(Reference drawing 2101779-AI provided with the kit.)
1. Install thermowell into meter run and tighten.
2. Install the ½” stainless steel nipple into the thermowell and tighten.
Figure 5 (RTD Probe Assembly)
3. Separate the union and install the female end of the union along with
its nut onto the nipple and tighten. With the RTD Head still loose,
screw the male end of the union into the bottom of the Head and
tighten.

8
4. Insert the RTD sensor probe down through the top of the RTD Head
and holding the sensor probe from underneath the Head, turn the
probe screwing the spring into the threaded hole in the terminal
block. Stop when the top of the spring is flush with the top of the
terminal block. If the probe came with a terminal block, remove it,
since there should be a terminal block already mounted inside the
RTD Head.
5. Guide the sensor probe down through the bottom half of the union.
As the two halves of the union come together, you should feel some
resistance as the sensor probe contacts the bottom of the
thermowell. You should see the top of the probe rise (3/4” max.)
above the terminal block as you push the two halves of the union
together. If the assembly is to long or to short, you may need to
change-out the nipple for a different length.
6. Slide the union nut up and screw on to the top half of the union but
do not tighten.
7. Align the RTD Head such that the connecting conduit or cable will be
pointing in the desired direction and then tighten the union.
8. Install the probe wire spade lugs under the small screw heads per
drawing. One color (typically white) is one side of the RTD and will
go to the RTD (Out & +) connections on the 6200EX and the other
color (typically red) is the other side of the RTD and will go to (In & -).
See Figure 9 on page 12 for a view of the 6200EX RTD terminals.

Procedure:
Note: Step 1 and 2 are not required if pipe is tall enough without the
extension. (Reference Fig. 7 for the following procedure).
1. Attach 2-inch pipe collar to top end of the 6200EX mounting pipe.
Securely tighten.
2. Install a 2-inch pipe extension into collar and securely tighten.
3. Install Solar Panel on mounting bracket with provided hardware.
4. Attach Solar Panel mounting plate to top end of 2-inch pipe with U-
bolts and associated mounting hardware. Do not tighten U-bolts until
Solar Panel has been correctly oriented.
5. If needed, connect Solar Panel power cable to Solar Panel connector
on back of unit. DO NOT connect the other end of Solar Panel
wiring to the OEU (Optional Equipment Unit) until all steps are
complete AND main battery pack has been connected.
6. Position Solar Panel to face south in the northern hemisphere and
north in the southern hemisphere. Tighten U-bolts securely to avoid
movement by wind or vibration.
7. Check solar panel polarity using digital voltmeter to insure (+) and (-)
wires are properly identified.
8. The Solar Panel power cable connects to the Array Input terminals
(See Fig. 10). Remove one of the hole plugs from the OEU and
install cord connector. Remove nut, sealing ring and rubber grommet
from cord connector. Slide nut, sealing ring and grommet over cable
and insert cable through body of cord connector. Allow enough
power cable to extend into the unit for connection to Array Input +/-
terminals.
9. Secure Solar Panel cable using grommet, sealing ring and nut.
Tip: To prevent moisture from entering the enclosure, allow cable to "dip"
below, and then rise to access hole. This will provide a path for
rainwater away from the access hole.

Battery Installation (6270 OEU Only)
1. To extend the life of the 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
can’t provide, improves the life of the battery. (See tip below)
2. Insert the battery pack into the battery compartment with its long
dimension facing outward.
3. Verify that the covers are screwed onto the 6200EX, then
connect the battery to one of the battery connector mates.
4. Observe the LCD on the 6200EX; the display should power up
displaying Warm Start information and begin scrolling through
the default display items.
5. Connect solar panel power cable to the Array inputs of the
charger/regulator inside the OEU.
Tip: To recharge a battery, a quick charge will remove the buildup in the
battery much more effectively than a "trickle charge". A battery
slowly drained by low light conditions on a solar charged system or
setting in storage will be less likely to recover than a battery pack
that was discharged quickly. Store batteries in a cool environment
for less drainage.
Lithium Battery
Verify that the LL (low lithium alarm) is not being displayed on the A7
annunciator (default). This alarm indicates the Lithium battery is not
connected or is below 2.5 volts and should be replaced. To verify the
battery is connected and/or is good, remove the front cover of the
6200EX and look for 4 vertical solder pads behind and to the upper
right side of the display (Fig. 8). This is the back side of the battery
connector. The very bottom pad is the Positive(+) and the very top is
negative(-) side of the battery. This is a confined space, so place the
ground lead of a voltmeter on bare metal such as the plate behind
the display and put the positive lead on the bottom solder pad being
careful not to get the lead against ground.

Radio Communications
The XFC6200EX was designed such that the customer would provide
local power and communications if required. However, in those cases
where power is not available and solar power is required, the Model
6270 Optional Equipment Unit can be used. The 6270 enclosure has a
charger/regulator module designed for solar input power and is typically
fitted with a solar panel and a 26 amp-hour battery. This is ample to
power the 6200EX flow computer and maintain some amount of
autonomy.
In situations where radio communication is required, the power
requirements of some radios might compromise the autonomy of the
system. This problem can be handled in the following ways:
1. Upgrade to the larger Model 6770 Optional Equipment Unit which
can handle a 42 amp-hour battery or two 26 amp-hour batteries.
2. Use low power radios such as the FreeWave® Spread Spectrum
radio.
3. Use radios that have a Sleep feature which lets the radio go to sleep
via a control line going low and then wakes up when the control line
is driven high or allowed to float. Totalflow has a Power Scheduler
application that runs in the 6200EX and switches an output called
COM1SW on COMM 1 and COM2SW on COMM 2. This is a FET
output which when in the OFF condition provides a path to ground
and when turned ON appears as an open. This may sound
backwards, but was designed this way to support radios with the
Sleep function.
4. Switch the radio’s power off when not in use. Since the COM1SW
and COM2SW signal does not provide a switched voltage, the user
will need to provide an interposing relay to switch the radio’s power
on and off. In order to do this, the enclosure is required to be in a
General Purpose area since adding the relay compromises the
enclosure’s Division 2 certification. Below is a simplified drawing of
how this would work. Due to the polarity of the COMSWs, the radio
will need to be connected to a normally closed set of contacts.
Figure 11 (Using Interposing Relay)

15
Remote Communications
The following discussion deals primarily with communications between
the 6200EX and Host (typically WinCCU).
To communicate with the Host, the 6200EX uses the remote
communications port (Comm 1) that can function as RS232 or RS485. If
the 6270 OEU was ordered, the customer had several communications
options to choose from.
After installation of the 6200EX and with the communications path
complete, the user needs to enter the appropriate communications
parameters. The 6200EX was most likely shipped with Comm 1 set up
for Totalflow Remote Protocol. If not, select the protocol using the Entry
mode of PCCU32 as shown below. 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 symbol may not be visible if the
baud rate is above 2400. See Alarm & Status Codes on page 19 for a full
description of alarm characters, locations, and descriptions.
Other Communication Options
After selecting the protocol, verify the other communication parameters.
All communication parameters with the exception of modems are found
on the Setup and Advanced tabs (See Fig. 12). Modem parameters have
there own tab. Systems are shipped with default settings for
communications but may need fine tuning. The Schedule tab parameters
are only required if the user wants to power-up the communication’s port
and communication’s devices on and off at designated times to conserve
power.
Figure 12 (Communications Setup)

16
Communications Troubleshooting
A new radio or modem system that doesn’t communicate is sometimes
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 trouble shooting technique. A checklist follows as
an aid.
•Does the " " symbol flash (Totalflow Remote Protocol only) with the
Listen Cycle time in the A8 display (default position)? If no,
Note: You may not see the " " symbol flashing where baud rates are
set higher than 2400. You may need to set the baud rate to 1200 to
see if port is active and then set it back to the desired baud rate.
1) The protocol needs to be selected in the Entry Mode using
PCCU32.
2) Inadequate DC voltage (9 volts minimum). Or as specified by
user in Station Setup of PCCU Entry mode.
•Insure base radio is working for other locations.
•Verify Station ID and Device ID matches with WinCCU and is the
only device with that ID.
•Verify Baud rate, Stop Bits, Security Code, and Listen Cycle time are
the same as WinCCU.
•Verify WinCCU is using Packet Protocol. The 6200EX only supports
DB2 Packet Protocol.
•Verify wiring from the 6200EX to the 6270 enclosure terminal strip
and terminal strip to radio. Verify cable from the radio to the antenna.
•Verify SW1 or SW2 switches on the 6200EX termination board are in
the proper position. (See Fig. 9 on page 12)
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 device to another. If black and
white wires are to be tested, disconnect both wires at both ends,
put 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 devices are apart.

17
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 that the radio is good,
with the same frequencies used for base radio and remote.
•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 available. Insure phone number is
correct in the 6200EX and WinCCU.
Note: The telephone company uses a 48 volt power supply so the
typical 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.
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.
Wiring Documentation
Specific wiring drawings are sent with each 6200EX based on the
options ordered. Many wiring diagrams, including communications are
available on the web at http://www.abb.com/totalflow. To see if a diagram
is available, go to the web site, Select “Continuing Customer Service and
Support”, and then select “Wiring Instructions”. Communications pin-outs
of the 6200EX are shown on page 12 of this guide.

Standard Displays
Items that appear on the device’s display are programmable by the user,
however based on the measurement application; units will be shipped
with some default display items. The following table is a typical set of
default displays for an AGA-3 application. Engineering units may vary

Visual Alarm & Status Codes
After the 6200EX completes recording 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
6200EX’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 3 will appear on the lower right
side of the LCD screen (see Fig. 13 below). Descriptions of each code
are described in Table 3.
Figure 13 (Annunciator Locations)
Note: Applications in a 6200EX device can be assigned to any
annunciator. To verify the current assignments, see Annunciators
