System Requirements The B‐Series use the XMODEM communication protocol via USB port, or the MODBUS protocol via RS‐485 port or MODBUS TCP/IP. The Kurz USB device driver or FTDI USB device driver must be installed before attempting to connect a computer with a B‐Series device via a USB cable. The B‐Series devices require: A two‐wire shielded cable for Modbus RTU. • For the XMODEM protocol, a USB Type A‐to‐mini B cable. • The Kurz USB device driver or FTDI USB device driver must be installed Note before attempting to connect a computer with a B‐Series device via a USB cable. For the Modbus TCP/IP protocol, an Ethernet cable to a Modbus TCP/IP to RS‐485 gateway. • Software Requirements KzComm is supported on Windows XP, Windows Vista, Windows 7, and Windows 8. All platforms require up‐to‐date service packs. On Windows Vista, downloading the Trend Log has infrequently caused Note the operating system to freeze (no screen activity). Restart the computer as described in your computer hardware manual. Basic computer knowledge is necessary for copying and moving files, navigating file structures, identifying file types, and installing applications. You will need a decompression utility to extract files from compressed file packages. The Kurz USB device driver or FTDI USB device driver must be installed before attempting to connect a computer with a B‐Series device via a USB cable. Both drivers are available during the KzComm installation, on the Kurz customer CD in the USB Device Driver folder, and on the Kurz website (kurzinstruments.com).

Page 17: Boot Mode
Table 1‐1. Nominal Boot‐Up Times Settling Time Cold Sensor Hot Sensor (1% Reading, Modbus, 4‐20 mA, or Display) (Power Off) (Power Cycled) 1600 SFPM, velocity, filter TC = 0.5 seconds 15 seconds 17 seconds 1600 SFPM, temperature, filter TC = 0.5 seconds 10 seconds 13 seconds Zero flow, velocity, filter TC = 0.5 seconds 15 seconds 60 seconds Zero flow, temperature, filter TC = 0.5 seconds 10 seconds 55 seconds The B‐Series flow meter can boot‐up and start responding to Modbus communications or updating the 4‐20 mA output and display within one second of restarting/powering up. However, the boot sequence has to complete to guarantee the integrity of the data, and it is generally recommended to wait an additional 20 seconds before issuing any commands. A near zero flow rate can cause a boot delay up to 2 minutes, during which time the velocity sensor must cool off so its resistance value can be checked to ensure there are no sensor faults. A high process velocity during boot‐up reduces the delay because the hot sensor can cool down faster. When the meter is turned on from a power‐off state, the NE‐43 alarm low (3.6 mA or less) is set until the sensor boot process starts. The flow and temperature will then increase to their proper values depending on the process velocity meter filter settings. Firmware version 1.10 and later hold the NE‐43 alarm until boot‐up and Note sensor stabilization complete. Kurz B‐Series Operations Guide 1–5...

Page 45: Totalizing Volume Or Mass Flow
Determining Accuracy Limits Data for the flow totalizer is retained in less than eight digits. Round‐off errors cause mistracking to occur when the data has been accumulating for extended periods (more than two years). To maintain mistracking below one percent, select an automatic roll‐over value that occurs within two years as a point for resetting the flow totalizer. This value is independent of the flow rate. See “Resetting the Flow Totalizer Value” on page 2‐10 for additional information. For example, a typical flow rate of 100 SCFM that occurs for 10 hours per day results in a total flow per day of 100 x 10 x 60 = 60,000 CF. In one year this accumulates 60,000 x 365 = 21,900,000 or 21.9 MCF per year. Configuring the flow totalizer to automatically reset at 10 MCF would force it to reset about every 6 months.

Page 83: Cleaning A Sensor
Using the Integrated Purge Controller The B‐Series is available for single‐point or multi‐point applications with a purge version that incorporates a purge control timer and data‐hold function built into the flow transmitter. The cleaning sequence can be initiated from: Internal flow meter timer • External contact closure • Write Coil command via Modbus • HART command • The Purge version of the flow meter provides an automated cleaning method to remove as much dirt buildup as possible using high velocity gas on the velocity sensor. This purge method is very effective at increasing the intervals between manual cleaning. In many cases it has altogether eliminated the need for manual cleaning, significantly reducing the cost of ownership. The purge gas can be at ambient temperature or heated to the process temperature. The advantage of using heated purge gas is that it does not condense any of the process gas onto the sensor, which could cement the dirt onto the sensor instead of blowing it off. Data is held during the Purge cycle. Implementing the internal timer with the cleaning control makes it easier to be independent of the process operation. The only verification for an active Purge cycle is querying a status register through Modbus (register 1XXXX ‐ coil status #8). The meter’s process variables (flow, velocity, and temperature) are held at their values prior to the start of the Purge cycle. Going from a dirty sensor to a clean sensor will show a spike in the flow rate and velocity after the Purge cycle completes. For applications that need tight control of the operation, the external contact closure offers the best results. Kurz B‐Series Operations Guide 2–47...
Page 84: Wiring For The Purge Controller
Wiring for the Purge Controller The purge controller setup requires connecting a 24 VDC 12 W maximum solenoid to the DO2 or solid state relay channel #2. Pin # TB6‐1 is +24 VDC and TB6‐2 is the GND connection. See the field wiring diagram for an example of the solenoid wiring. The recommended wiring gage is 18 AWG (1.02 mm), although the gage and length are not critical for this connection. This wiring information only applies to the Purge version of Note model 454PFTB‐16. To activate the purge with an external contact closure, the contact closure is on pins TB6‐8 or digital input 1 (DI1) and GND, TB6‐5. The width of the activation pulse must be at least 25 ms long, and the purge will start on the leading edge (or falling from logic high to low). Assigning a Relay to the Purge Function To use the sensor purge cleaning feature of the meter, relay #2 must be assigned to PURGE OUTPUT. To set the purge relay assignment in Program mode: Press P. 1> Enter your advanced access password, and then press E. 2> Press 2 to invoke the Quick Jump option. 3> Press 8 for the Relay Output Setup menu, and then press E. 4> 2–48 Kurz B‐Series Operations Guide...

The previously assigned function is now unassigned and turned off, when applicable. The user interface advances to the Setup Sensor Purge function (menu option 12). Changing the Purge Controller Configuration The first parameter in the Setup Sensor Purge menu turns the Purge Timer ON or OFF. When set to ON, the sensor purge cleaning sequence is initiated by an internal timer in the flow meter. The PURGE TIMER does not need to be ON for the purge to be initiated Note via Modbus, HART, or the external contact closure. PURGE TIMER >ON ^v Press the arrows keys to set the parameter to ON, and then press E. 1> If Relay #2 is used by another function, the following prompt appears: DO2 IS USED CHANGE IT>NO Press the arrow keys to change the response to YES, and then press E. 2> Kurz B‐Series Operations Guide 2–49...
Page 86 After the PURGE TIMER is turned on, the menu confirms the relay assignment with the following prompt: PURGE OUTPUT ASSIGNED to DO2 Press E or P to continue. 3> The PURGE TIME prompt appears. This is the length of time the purge solenoid is held open. PURGE TIME MSEC >500 Use the numeric keys and type in the number of milliseconds to hold the purge solenoid 4> open during the purge, and then press E. (A short blast generally works best.) The HOLD TIME prompt appears. The HOLD TIME allows the sensor to recover from the purge by masking off the large flow spike following the purge. It can be a function of the purge gas temperature compared with the temperature of the process gas being measured. A longer HOLD TIME may be needed if there is a large temperature difference between these two variables. Following a purge, lower flow rates typically need more recovery time than higher flow rates. A cleaned sensor changes the flow readings following a purge regardless Note of the specified hold time. Additionally, the rate at which the shift occurs is filtered by the meter time constant setting. The HOLD TIME applies to the update of the flow rate, velocity, and temperature values with respect to the 4‐20mA output, Modbus output, and display. The HOLD TIME is the total time for the entire purge cycle. For example, a HOLD TIME of 2000 milliseconds with a PURGE TIME of 500 milliseconds means that the Purge Relay will be pulsed for 500 milliseconds, followed by an additional 1500 milliseconds of idle time to allow for sensor recovery. The HOLD TIME value must be greater than or equal to the PURGE TIME Note value. 2–50 Kurz B‐Series Operations Guide...
Page 87: Operating And Monitoring Purge Cleaning Using Modbus
> 60 The PURGE INTERVAL can be from 1 and 1440 minutes. Use the numeric keypad and type the number of minutes for the desired PURGE INTERVAL, 6> and then press E. Operating and Monitoring Purge Cleaning Using Modbus The purge sequence can be triggered by writing a 1 to the Modbus coil #8 (Register 0X). This operation does not require the purge timer to be ON; however, Relay #2 must be assigned to the PURGE OUT function. Once started, the Modbus purge operation ignores Program mode purge commands. The Modbus purge trigger is independent of the internal timer. For example, if the Program mode purge interval is configured for 60 minutes, any Modbus purge commands are performed without affecting the internal timer purge sequence. The status of the purge via Modbus is provided at coil status #8, (Register 1X). A value of 1 indicates it is in the middle of a purge cycle, and a 0 indicates the cycle is idle. An in‐process purge sequence initiated through HART takes precedence Note over a purge sequence initiated through Modbus and causes the purge sequence initiated through Modbus to be ignored. Operating and Monitoring Purge Cleaning Using HART The parameters for setting up the purge sequence can be changed through the HART interface. Device‐specific commands 137, 138, and 139 are used for the B‐Series purge cleaning through the HART Master. The B‐Series Field Device Specification describes the format of these commands. For HART Masters using the B‐Series Device Descriptor (DD) files, the Purge Setup menu and purge method are available, as shown in Figure 2‐4. Refer to the HART Interface Guide for information about the B‐Series DD menu organization. Kurz B‐Series Operations Guide 2–51...

An in‐process purge sequence initiated through Modbus takes Note precedence over a purge sequence initiated through HART and causes the purge sequence initiated through HART to be ignored. Automatically Triggering Drift Check and Purge The Sensor Purge and the Drift Check zero, mid, and span parameters are two flow meter functions that can be configured to automatically trigger on a user configured interval. If both timers for these functions are turned ON and scheduled to initiate at the same time, the meter will run the activities consecutively (not concurrently). 2–52 Kurz B‐Series Operations Guide...
