Page 18: Boot Mode
The B‐Series flow meter can boot‐up and start responding to host 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 is set until the sensor boot process completes. The flow and temperature will then indicate their proper values. When you boot‐up (power on) the flow meter, the display progresses through a series of initialization indicators: KURZ INSTRUMENTS DISP DRIVER V4.X CHECKING TYPE OF CONNECTED SENSOR WAIT PERFORMING SENSOR LEAK TEST KURZ INSTRUMENTS SERIES MFT-B FIRMWARE VERSION MFT-B VER 2.XX If the device supports Hart communication, an H appears before the Note firmware version number. ...
Page 19: Run Mode
B‐Series Flow Meter Modes & Menus Once bootup completes, the flow meter automatically goes into Run mode. An error message indicates the unit has failed boot‐up testing due to a sensor mismatch, wiring, or other problem. The device will cycle through boot testing again until the issue is resolved • (for firmware 2.03 and earlier). Downloading the Min/Max, Event, and Trend logs is not possible until Note boot testing completes successfully. You can force a boot exit by pressing the C key. • Once bootup completes you can start downloading the Min/Max, Event, and Trend logs. Run Mode Run mode is the normal operational state of the meter after Boot‐Up mode. The default display format in Run mode is “scroll all.’ The following example shows the flow meter’s tag name and flow: TAG NATURAL GAS1 FLOW 0.0000 SCFM Firmware version 2.0 and higher allows you to determine how process variables appear in Run mode. Setting the Run mode display format is available by selecting option 7 in Program mode with the Advanced access code. You can also access the Run mode display format by selecting option 1 in Program mode with the Basic access code, although you must scroll through the entire basic setup. See Option 7 in the Program Mode — Advanced Access chapter for more information. 1–6 Kurz B‐Series Operations Guide...
Page 20: Program Mode
“Program Mode Advanced Setup”) is used for changing advanced flow meter parameters, such as time constants and access codes. Before making any configuration changes in Program mode, it is important to remember: Any configuration changes are automatically saved to EEPROM when the flow meter exits • out of Program mode. There are no prompts to confirm changes. To back out of a series of menus, continue to press H for each level (manual exit). • If there is no menu activity for 3 minutes, the display automatically exits to Run mode. Any • changes made before the auto‐exit are saved to EEPROM. The configuration is retained through flow meter reboots and power cycles. • You should not make any changes to the meter configuration without a Important complete understanding of the flow meter parameters. Changing a setting incorrectly can cause the flow meter to malfunction.

Page 101 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. Lower flow rates typically need more recovery time than higher flow rates following a purge. 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 4‐20 mA 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. Use the numeric keys and type in the number of milliseconds for the desired HOLD TIME, 8> and then press E. PURGE INTV MIN > 60 The PURGE INTERVAL prompt appears. The PURGE INTERVAL is used to set the frequency (in minutes) of the purge cycle when it is triggered by the internal timer.

If the internal timer and the external purge contact closure are used to start the purge, set the internal timer PURGE INTERVAL to a value higher than is specified by the external closure. This will prevent the internal timer from purging too soon after the last externally commanded purge. The PURGE INTERVAL can be from 1 to 1440 minutes.

Page 151: Specifying Drift Check Triggers
Flow Meter Configuration Specifying Drift Check Triggers There are four ways to initiate the zero‐mid‐span drift check: A specified time interval • An external contact closure through digital input #2 • A menu option in Extended Utilities mode • A Modbus command • The duration of the individual zero, mid, or span checks are controlled by user‐specified duration values. Specified-Time Interval Drift Check The zero‐mid‐span check can be triggered by the drift check interval time. To configure this option, turn ON the Auto Drift Check. When it is triggered, it will perform the zero, mid, and span sequence. Change the value of the drift check interval to change the frequency that the drift check starts. See “Option 23 — Drift Check” for information about setting up drift check. External Digital Input The external digital input trigger does not require that Auto Drift Check be turned ON. When the flow meter digital input (DI) channel #2 is grounded, the meter initiates the zero‐mid‐span drift check sequence. While the system is busy performing the drift check sequence, it will not accept another command via the digital input. After the drift check sequence completes, the meter monitors the DI channel for the next request to initiate a drift check. If a specified time internal drift check is underway while an external drift check is triggered, the external drift check will start after the internal drift check completes. 6–2 Kurz B‐Series Operations Guide...

The status register bits are also used to report the diagnostic errors on the flow meter (function code 02). This permits fast status polling along with the principle variable polling. Refer to Chapter 4, Troubleshooting, in the Kurz Hardware Guide for a list of registers. A drift check triggered through Modbus is a bit or coil write command with status. The amplitude values (% 4‐20 mA scale) and the duration (seconds) for each drift check are available as read and write registers. The results from a previous drift check (using volts measured from the internal 3.3 V programmable reference, not 4‐20 mA range) and percentage change are also available as read registers. 6–4 Kurz B‐Series Operations Guide...

RPM. To use the B‐Series as an automatic flow controller, connect one of its 4‐20 mA outputs to the control valve, damper, or motor controller. It will regulate the flow based on a fixed flow set point value or an analog input for the set point. The following example has the B‐Series flow meter actuating a valve based on an external set point of the flow rate. The second 4‐20 mA output channel is sending the flow rate signal elsewhere, although temperature can be specified instead of flow rate. PID control of the process is manually configured. The control output can be controlled manually from the display to verify the range operation of the control loop or to manually set the output (control valve) at a fixed position.

Page 156: Cleaning A Sensor & The Purge Controller
Flow Meter Configuration Cleaning A Sensor & The Purge Controller The sensor was calibrated clean, and operating it clean preserves the best calibration. Any material that builds up on the thermal sensor can insulate it, causing it to lose less heat and read lower than when it was calibrated. Refer to the Kurz Hardware Guide for information for information on manually cleaning a dirty sensor. Operating a dirty sensor that is field‐calibrated with a correction factor for the proper flow rate tends to be unstable. After a process stops and cools down, the dirt buildup frequently flakes off. This causes the sensor to read higher when the process restarts. The absence of the insulating dirt causes the pre‐ and post‐shutdown data from the same operating point to mismatch. This problem can be largely avoided by initiating an automatic cleaning system. 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 through digital input #1 • Write Coil command via Modbus • HART command • The Purge version of the flow meter provides an automated cleaning method to remove as much ...

Purge Time Output Purge Start Contact Closure Interval Interval Internal Purge Timer Hold Time Flow Data Output Figure 6‐1. Masked purge blast 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 the Note Series 454PFTB. The contact closure for activating the purge is on pins TB6‐8 or digital input 1 (DI1) and ground (TB6‐6). 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). 6–8 Kurz B‐Series Operations Guide...
Page 158: Assigning A Relay To The Purge Function
Operating and Monitoring Purge Cleaning Using Modbus The purge sequence can be triggered by writing a 1 to the Modbus coil #8 (function 5). 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, (function 2). 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. Refer to the HART Interface Guide for information about the B‐Series DD menu organization. If the Purge Timer has been turned ON, the purge cycle initiated through the HART interface will not affect the purge sequence controlled by the internal timer. 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.
