Introduction This manual is designed to provide an experienced flow meter technician with the requirements necessary to install, set up and operate a Totalflow XFCG4 6200/6201EX. Organization & style Each of the chapters in this manual presents information in an organized and concise manner.
Page 11: Safety Practices And Precautions
Intended to draw attention to a statement that might keep the user from making a mistake, keep them from destroying equipment or parts, or keep them from creating a situation that could cause personal injury if caution is not used. Please refer to the Safety Practices and Precaution section for additional information.
Page 12: Safety Guidelines
Additionally, it should be pointed out that the following instructions are neither part of nor provided for changing a previous existing agreement, promise or legal relationship. The obligations adhered to by ABB Totalflow result from the respective sales contract which also comprises the complete and solely valid warranty clauses.
Page 13: Equipment Markings
STOP. Do not proceed without first verifying that a hazardous condition does not exist. This task may not be undertaken until proper protection has been accomplished, or the hazardous condition has been removed. Personal injury or fatality could result. Examples of these warnings include: Removal of enclosure cover(s) in a hazardous location must follow guidelines stipulated in the Certification Drawings shipped with this unit.
Page 14: Safe Equipment
Compliance EU Directive 2012/19/EU - Waste Electrical and Electronic Equipment (WEEE) ABB Industrial Automation, Measurement and Analytics, is committed to actively protecting the environment. Do not dispose of WEEE as unsorted municipal waste. Collect WEEE separately. Participation in the management of WEEE is critical to the success of WEEE collection.
Page 15: System Description
1 System description Overview The XFC 6200/6201EX (G4 EX) is a next generation solution for the pre-existing generation 3 XFC6200/6201EX. The G4 EX now incorporates the same 32-bit technology currently used by the G4 XSeries products. By using 32-bit technology, ®...
Page 16: Capabilities
1.1.1 Capabilities The G4 EX is packaged in a small, explosion-proof cast aluminum enclosure which accommodates the processor board, termination board and display. The power supply, charging source and radio communication applications must be housed in separate accommodations. See Figure 1–1. For the G4 EX, the integral multivariable transducer (EXIMV) is a separate unit with no internal electronics and is attached to the bottom of the enclosure via a threaded neck.

Sample set of most recent calculations allowing subsequent verification. Monitoring of the operational limits, minimums and maximums to ensure detection and reporting of malfunctions or abnormal site conditions. Acceptance and storage of system constants from the PCCU32 or remote communications protocols. Storage of data records and operational events is determined by user (based on available memory).
Page 19: Display Function
Choosing a log period of less than 60 minutes will result in additional records being logged. As a result, this requires more storage space to hold a full day’s data. The log period must never be less than the volume calculation period. 1.1.4.2 Volume calculation period entries Volume calculation period entries are made every second, by default.
Page 20: Figure 1-2 Liquid Crystal Display (Lcd) And Indicators
In the G4 EX computer, the status and alarm indicators are user programmable. Table 1–3 identifies the default annunciator locations. Please consult the PCCU32 Help Files for additional instructions on programming the annunciators. Whenever an alarm is indicated, the G4 EX records it in the appropriate log period flow record.

Page 35: Solar Panel
The battery compartment shelf houses various optional battery packs that are available for the OEU, from eight (8) ampere hours up to 26 ampere hours. Installation of the battery is discussed later in the manual. The 6270 OEU system with battery and solar panel is rated for Class I, Division 2 locations only or can be installed in non- hazardous locations.
Page 36: Lithium Battery
Figure 1–19 Solar panel – typical installation 1.2.9 Lithium battery The following information displays the technical information regarding the lithium battery housed within the G4 EX. When the G4 EX is in storage, it is recommended that the lithium battery be disabled (unplugged from J5 connector) to prevent power drainage.
Page 37 From the factory, the G4 EX has four general credits installed. Several system configurations are possible with these four general credits: AGA-3 with Plunger Lift and Trending (uses 3 general credits) Two AGA-3 (or AGA-7) tubes with Trending (uses 3 general credits) AGA-3 with Pad Control and Plunger Lift (uses 3 general credits) Applications are divided into categories: standard, general, IEC and CO2.
Page 38: Credit Key (Usb)
1.3.1 Credit Key (USB) The G4 EX comes with four general credits installed in the unit. If the system configuration requires more application credits, they can be purchased from Totalflow’s Order Entry (1-800-442-3097). Credits (standard, general, IEC and CO2) are maintained on the credit key. Credits can be purchased and kept on the USB credit key.

Page 104: Changing The G4 Ex Clock
Changing the G4 EX Clock When any measurement applications are instantiated on the G4 EX, changing the clock could affect the time when log period entries are made. To protect the integrity of the accounting audit trails, the G4 EX handles these types of clock changes as follows: 4.6.1 Clock Change Not Crossing an Hour Boundary When the next log period entry is made, the clock is not altered.
Page 105: Step-By-Step Instructions
To extend the lift of the battery pack, fully charge the battery prior to installation. A system using solar panels may not fully charge the battery. Additionally, a fast charge, which the solar panel cannot provide, improves the life of the battery. To recharge a battery, a quick charge will remove buildup in the battery much more effectively than a trickle charge.

If a method other than compressed nitrogen/deadweight tester is used to calibrate the static pressure cell, the user must ensure that the prescribed flange type valves are blocked to prevent false differential pressure from being applied to the DP cell. Additionally, ensure that both high and low sides are pressured up during SP calibration.
Page 119 2) Select SP from the Calibration drop-down menu to the left of the Pressure Marker table. 3) Select the SP type: Absolute or Gauge. Absolute will display values with the barometric pressure added in. Additionally, entered values will need the barometric pressure added.
Page 120: Differential Pressure (Dp) Calibration Checks
Figure 4–12 Calibration diagram 4.13.4 Differential pressure (DP) calibration checks As discussed in section 4.13.3, it is recommended that checks of the differential pressure (DP) be performed prior to and directly following calibration. A minimum of three differential pressure markers should be set; however, the user may enter as many DP pressure markers as they prefer.
