13 Section 2 Installation

14 Universal IV CM Density Compensated Model Section 2: Installation 2.1 Mounting the Unit There are 2 electronic units for the Density Compensation Cut Monitor. The DCM is a remote mounted unit. This module has connections for 24 VDC power, a 4 20 ma signal loop, Modbus digital output and a relay (SPST). The Cut Monitor Transmitter is either mounted integral to the probe or remote mounted. This unit is connected to the probe and power is provided by the Density Compensation Module. Reference the Universal IV Cut Monitor manual for mounting of this module Remote electronic units are designed for field mounting, but should be mounted in a location as free as possible from vibration, corrosive atmospheres, and any possibility of mechanical damage. For convenience at start-up, mount the instrument in a reasonably accessible location. Ambient temperatures should be between -40 F and 167 F (-40 C and 75 C) Spool Probe Cut Monitor (CM) Density Compensation Module (DCM) 7

15 Installation 2.2 Wiring the Electronic Unit Direct Connection to Coriolis DIrect Connection to a PLC 8

16 Universal IV CM Density Compensated Model Power Wiring to Universal IV CM to the DCM Module The DCM backboard wiring to the CM must go through the bottom of the DCM housing or else the transmitter will not secure properly. Due to the potential for switching interference on the relay it is recommended the relay wires exit the housing via the opposite port of the other wiring entering the housing. If trying to communicate via HART on the 4-20 Loop, you must have a 250Ω Resistor. 9

17 Installation Universal IV CM Wiring Due to the low power consumption of the instrument, the wiring need only be light gauge (e.g. 20 AWG) between the Density Compensation Module and Cut Monitor Module. Remove the DCM electronic unit to access the Customer Wiring Terminal Board. This is accomplished by unscrewing the 2 screws at the 3 o clock and 9 o clock positions. The captive screws can then be used to lift the electronics from the housing Density Compensation Module Wiring The signal connections are made to the terminal block on the front of the Density Compensation Module chassis Power Wiring Due to the low power consumption of the instrument, the wiring need only be light gauge (e.g. 20 AWG). Shielded twisted pair cables are recommended Supply Voltage requirement is 19-30VDC. *Shield wire may be Grounded at the identified housing screw or cut depending on the power configuration. Ground Screw 10

18 Universal IV CM Density Compensated Model (4-20mA) HART 7.0 Signal Loop Wiring Due to the low power consumption of the instrument, the wiring need only be light gauge (e.g. 20 AWG) for the 4 20 ma signal loop. Shielded twisted pair cables are recommended. Supply Voltage requirement is 19-30VDC. Minimum loop resistance for HART communications is 250 Ω. Minimum 22mA is required at the 4-20mA input terminals. *Shield wire may be Grounded at the identified housing screw or cut depending on the power configuration Ground Screw 11

19 Modbus Communications Wiring Installation Due to the low power consumption of the instrument, the wiring need only be light gauge (e.g. 20 AWG) for the Modbus digital output. Shielded 3 wire cable is recommended. 12

20 Universal IV CM Density Compensated Model Master & Slave Wiring Configurations Master In the Master configuration the DCM is the Modbus master and requests density, temperature and flow rate data from the connected slave device (Coriolis, PLC, etc.). The corrected Water cut is transmitted to the control system from the DCM via the 4 20 ma loop and all other parameters via HART Slave In the Slave configuration the external Modbus master, typically a PLC, is writing density, temperature and flow data to the DCM slave. The corrected Water cut is transmitted back to the control system from the DCM via the 4 20 ma loop and all other parameters via HART SPST Relay Wiring Selection of the wire size should be based on the power that will be switched. Due to the potential for switching interference on the relay it is recommended the relay wires exit the housing via the left port and all other wiring exit the housing via the right port. 13

21 Installation 2.3 Initial Start Up Verify wiring configuration per section Power up the Cut Monitor (CM) and the Density Compensation Module (DCM) 1. If both units power up properly then skip #2 below 2. If both units fail to power up properly then verify the following voltage levels Minimum voltage at any of these points should be 19VDC. If not check the power supply to ensure sufficient output rating. 3. After obtaining proper voltages wait 60 seconds for full power up, proceed to next step 4. If the display shows a CRITICAL COMM LOSS error, verify the 4-20mA loop wiring 5. If the display shows a MB Master Invalid Response Failure the you may have an incorrect Modbus register address, this will be corrected later. 6. Confirm the Modbus wires are correct. Measure from A to B, voltage should be approximately 2.5 VDC. If it is negative, swap the Modbus wires. 7. Verify the loop current output matches at the PLC and DCM You may have to enable the 4-20mA Loop Display on the DCM. If so, proceed to Section 3.4. The displayed value of current does not matter at this point, only that they match. If they differ slightly, you can correct this later by performing a trim and calibration. 8. If they do not match, check wiring. If they do match, proceed to the next section. Validate CM Operation. 14

22 Universal IV CM Density Compensated Model 2.4 Validate CM Operation Verify the capacitance values on the CM and DCM match. 1. If they do not match, you shoul dsee a "HART 5 CRITICAL COMM LOSS FAILURE "on the DCM. To clear this, power cycle the CM only bu removing the 4-20mA leads on the CM for 10 seconds then replace them. If the capacitance values are still mismatched, it is likely a faulty cut monitor (CM) transmitter. Contact Drexelbrook Service department Verify matching capacitance values are appropriate for the application. <14pF pf >40 pf Problem Confirm Scenario Problem (A) While powered, remove CM transmitter from back board. If the CAP value changes on the tramsitter the transmitter is fine., go to (B). If the CAP value remains fixed, power cycle the CM transmitter and restart the CAP check. If the value continues to remain locked, replace the Cm transmitter. (B) While connected, remove the probe from the system. Touch the outside of the probe, if the CAP value doesn't change on the CM, replace the probe and the cable. (A) Remove CM transmitter. Liftprobe leads from the backboard. Ohm check probe ground (GND) and verify it is not shorted. If it is not OPEN, verify probe install. (Insure probe is plumb and not angled and hitting the wall of the pipe. (B) While connected, remove probe from the install; if CAP value drops sharply, then the probe was shorted. Check the probe installation If you have an expected value from the center column, the CM is operating normally in current conditions. Proceed ro the next section 2.5 Modbus Validation 15

23 Installation 2.5 Modbus Validation Establish Modbus communication. Note: The Coriolis provides a Density, Temperature and Flow output Insure that your Modbus wires are installed correctly. Using a voltmeter, measure between A & B terminals. Measurement should be approximately +2.5VDC Determine appropriate Modbus operatiung mode (either Master or Slave) in menu 5.1. Complete the worksheet at the end of this section to use as a reference. Function control of the PLC must be be in mode 4 [read/write] regardless of Master/Slave setting. If you ssee the following locked into the DCM then Modbus is NOT communicating with the DCM. Density --KG/M3-- Temperature --DEGC-- Flow --L/MIN When using the DCM as a Master: If possible, confirm these settings in a workshop prior to site installation with a Modbus simulator on a computer (in Master mode) with the PLC/Flow computer set up used. In our exaples to follow we are using "Simply Modbus" as our simulator. This will enable you to verify Function Control is correct, what Address format (see tabe below) is required for proper communication, as well as verifying hex values sent and received are appropriate. If using a MicroLink RS-485 Converter, ensure the red lead is connected to "B" on the DCM. Address Formt Chart Big Endian Low Byte 1st, High Word 1st Big Endian Swap High Byte 1st, High Word 1st Little Endian Swap Low Word 1st, High Byte 1st Littel Endian Low Word 1st, Low Byte 1st 16

24 Universal IV CM Density Compensated Model 2.5 Modbus Validation (Continued) The following image depicts data simulated as a Coriolis using "Simply Modbus" software. Your settings will likely differ. This is an example of good communicatons 17

25 2.5 Modbus Validation (Continued) In this instance, the green LEDs are lit signifying slave ID and Function Code (fc) match. The data is found and displayed properly, and the cyclic redundancy check (CRC) or checksum was completed successfully. The circled section in the log shows >>> Question from DCM and < Response from simulator/ PLC This is an example of bad communicatons Installation In this instance, the Modbus wires are incorrect, and must be swapped. The first 2 pairs of Hex values should match Slave ID (01) and function code (04) of the DCM. The LEDs are out signifying it is not set up correct, as can be seen with no response given. The circled section in the log shows >>> Question from DCM. There is no response from simulator/ PLC 18

26 Universal IV CM Density Compensated Model 2.5 Modbus Validation (Continued) Again, if you see the following locked into the DCM, Modbus is not communicating with the DCM Density --KG/M3-- Temperature --DEGC-- Flow --L/MIN If you see a density value on the DCM other than 830 KG/M3, data has been received. If the received data does not match the Coriolis, check your address format! Verify DCM density value matches Coriolis. If Coriolis is set to API and DCM is set to Density the measurements may be correct you must ensure the PLC is providing the correct unit conversion. If the DCM willdo do all the conversions, look at the settings for the scalers in STExplorer. Do not change the DCM to output API until the DCM is set up and the first calibration has been performed with oil flow in the system. This can be adjusted through Menu item 1.2 If they do not match, ensure the PLC is converting API to density. By default, the DCM is set to density, but may be changed to API through menu When using the DCM as a Slave: This method is not recommended unless you have a dedicated PLC technician or programer available. Refer to Modbus Register Maps, Section 3.6. Determine appropriate Slave Register Address to write to. Record units and values below.utilize these register addresses when programing your PLC Data Register Density API Density [ / ] Temperature [ Deg ] Volume Flowrate [ / min] Ensure the the DCM menu 5.1 is set to slave Calibrate. Once the system is communicating, prepare system for calibration. Proceed to section and pefrform 1st calibration point. A scond calibration point should be performed once you have a known deviation in API of product of at least 5 API. The greater the chnage the better the DCM can compensate. 19

31 Configuration and Calibration 3.3 Calibration Modes & Field Calibration Overview There are two different calibration and calculation modes supported by the CM-DC, Two Point and Multi-Cal calculation modes. Each mode is meant to address the different calibration needs of the various processes throughout the handling of crude oil in the oil and gas industry. In general, Two Point calibration is best suited for single stream crude oil handling application like wellhead LACTs. Under typical wellhead LACT applications, changes in oil density are small over time, typically 2-3 API max. Under these conditions, it is recommended that the DCM be configured for Two Point calibration mode and field calibrated per the corresponding calibration process indicated in this section. In oil handling application where it is common for oil API variation to be greater than 3 API or in application where multiple oil streams are processed through the same LACT system, MultiCal calibration mode can provide superior measurement performance. This material variation is typical in Truck Unloading and Rail Car collection stations. Under these conditions, it is recommended that the DCM be configured for MultiCal calibration mode and field calibrated per the corresponding calibration process indicated in this section Setting the Calibtration Mode Use the following procedure to configure the DCM calibration mode. 1. Navigate to the CAL MOD menu at address 2.4 and press ENTER to access menu. a. At his point, the DCM will be displaying the current calibration mode. 2. To change the calibration mode, press ENTER to edit the value, then press UP or DOWN to selected the desired calibration mode and accept the change by pressing ENTER. a. The new calibration mode is now active. 3. Press and hold the BACK button for 5 seconds to return to the meter display Adding a Calibration Point The procedure for adding a calibration point is the same whether the calibration point is for CUTCAL1 (menu address 2.1), CUTCAL2 (menu address 2.2), or MULTCAL (menu address 2.3). CUTCAL1 and CUTCAL2 are used when the DCM is in TWO POINT calibration mode and the MULTCAL menu is used when the DCM is in MULTCAL mode. Please see section for instructions on how to set the calibration mode. 24

32 Universal IV CM Density Compensated Model 3.3 Calibration Modes & Field Calibration (continued) Adding a Calibration Point (continued) Use the following procedure to add a calibration point to the DMC. 1. Navigate to the sub-menu for the calibration point to be added. Use menu address 2.1 for CUTCAL1, menu address 2.2 for CUTCAL2 or menu address 2.3 for MULTICAL and enter the sub-menu. a. NOTE: the X in the following menu address would be determined based on the calibration point being calibrated. 2. Store the required calibration data into the DCM by selecting the STORE function at menu item 2.X.1 and change the value from NO to YES and accept the change by pressing ENTER. a. This stores all the required calibration information into the DCM. 3. Retrieve a sample of the oil being processed and perform a Water Content Test to determine the true percentage of water in the process flow. a. The sample should be collected at the same time that step 2 was completed. This ensures the stored calibration data is representative of the collected sample. b. Either a centripetal or titration testing methods can be used. Which method to use is generally indicated by the site managing contractor. 4. Once the true water content of the collected sample is determined, store the actual water percent into the DCM by selecting the ACT CAL function at menu item 2.X.2. Enter the actual water percent of the sample and accept the change by pressing ENTER. a. This completes the calibration process. 5. Press and hold the BACK button for 5 seconds to return to the meter display. a. The H2O cut should read the entered water cut percentage Clearing a Calibration Point User calibration data can be cleared and reset to default values for either calibration points 1 and 2 as well as all multi point calibration data. This data is independently reset through a dedicated menu in each of the CUTCAL1 (menu address 2.1), CUTCAL2 (menu address 2.2), or MULTCAL (menu address 2.3) menus. To clear the user calibration data, complete the following procedure. 1. Navigate to the sub-menu for the calibration data to be cleared. Use menu address 2.1 for CUTCAL1, menu address 2.2 for CUTCAL2 or menu address 2.3 for MULTCAL and enter the sub-menu. a. NOTE: the X in the following menu address would be determined based on the calibration data to be cleared. 2. Clear the calibration data in the DCM by selecting the CLEAR function at menu item 2.X.3 and change the value from NO to YES and accept the change by pressing ENTER. a. This clears the calibration information in the DCM. 3. Press and hold the BACK button for 5 seconds to return to the meter display. 25

33 Configuration and Calibration 3.3 Calibration Modes & Field Calibration (continued) Two Point Calibration Two point calibration mode uses two fixed material calibrations to model the behavior of the process material being measured. Calibration of the DCM while in Two Point calibration mode involves teaching the DCM the electrical properties over a span of process temperature to ensure the proper correction due to temperature affects. Density correction factors are also calculated during this process. To perform a Two Point Calibration, complete the following calibration process Calibration Procedure for Point 1 1. Complete the initial commissioning process and insure the UIV CM-DC system is properly install and configured. Refer to section 2.0 for details on initial setup and commissioning. 2. Navigate the DCM to the CAL MOD menu at address 2.4 and verify the unit is set to TWO PT to activate the Two Point calibration mode. a. See section 3.2 Operating the User Interface for details on navigating the DCM menu system. b. See section Setting the Calibration Mode for details on verifying and changing the calibration mode. 3. Place the oil processing system into Normal Operating Mode. a. For LACT applications this means actively pumping oil through the wellhead LACT and allowing roughly 1-2 minutes for the system to stabilize and all air/gas to be removed from the system. b. For Truck/Rail Car unloading stations this means actively transferring oil through the unloading LACT and allowing roughly 1-2 minutes for the system to stabilize and all air/gas to be removed from the system. 4. Navigate to the CUTCAL1 sub-menu at menu address 2.1 and enter the sub-menu by pressing ENTER. 5. Add the new calibration point by following the procedure indicated in section Adding a Calibration Point. 6. Press and hold the BACK button for 5 seconds to return to the meter display. a. The H2O cut should read the entered water cut percentage Calibration Procedure for Point 2 1. Calibration of point 2 should be complete after point 1 is calibrated. For the best results, perform calibration of point 2 when the process conditions are at least 10 F different in temperature or 2 API different in density from point Navigate the DCM to the CAL MOD menu at address 2.4 and verify the unit is set to TWO PT to activate the Two Point calibration mode. a. See section 3.2 Operating the User Interface for details on navigating the DCM menu system. b. See section Setting the Calibration Mode for details on verifying and changing the calibration mode. 26

34 Universal IV CM Density Compensated Model Calibration Procedure for Point 2 (continued) 1. Place the oil processing system into Normal Operating Mode. a. For LACT applications this means actively pumping oil through the wellhead LACT and allowing roughly 1-2 minutes for the system to stabilize and all air/gas to be removed from the system. b. For Truck/Rail Car unloading stations this means actively transferring oil through the unloading LACT and allowing roughly 1-2 minutes for the system to stabilize and all air/gas to be removed from the system. 4. Navigate to the CUTCAL2 sub-menu at menu address 2.3 and enter the sub-menu by pressing ENTER. 5. Add the new calibration point by following the procedure indicated in section Adding a Calibration Point. 6. Press and hold the BACK button for 5 seconds to return to the meter display. The H2O cut should read the entered water cut percentage MultiCal - Multi Point Calibration MultiCal is used in applications where the process material is regularly changing. This is typical in truck and rail unloading stations as well as custom processes where batches of material are processed. This calibration and calculation mode holds up to 10 separate calibration points used to profile the material being presented to the CM-DC system. Once calibrated, the DCM will actively determine the calibration values to uses by searching all available calibration points and selecting the best match to the material currently being processed. When the next load/batch of oil is processed, the system will automatically reselect the best calibration settings. New calibration data can be added at any time and will automatically be managed by the DCM. For best results, at least 2 calibration data points should be added for each different material presented to the system. These 2 calibration points are recommended to be at least 10 F different in material temperature if possible. This can be done over the course of several hours or days as the availability of the material and its temperature allow. Other material calibration points may also be added between the time point 1 and point 2 of a given material are calibrated. Once all 10 calibration positions are filled, the DCM will begin overwriting the oldest calibration point. It is also recommended that if the DCM is indicating an accurate density corrected water cut percentage that the system NOT be calibrated as this may cause undesirable results. 27

35 Configuration and Calibration Calibration Procedure for MultiCal 1. Complete the initial commissioning process and insure the UIV CM-DC system is properly install and configured. Refer to section 2.0 for details on initial setup and commissioning. 2. Place the oil processing system into Normal Operating Mode. a. For LACT applications this means actively pumping oil through the wellhead LACT and allowing roughly 1-2 minutes for the system to stabilize and all air/gas to be removed from the system. b. For Truck/Rail Car unloading stations this means actively transferring oil through the unloading LACT and allowing roughly 1-2 minutes for the system to stabilize and all air/gas to be removed from the system. 3. Navigate the DCM to the CAL MOD menu at address 2.4 and verify the unit is set to MULTCAL to activate the Multi Point calibration mode. a. See section 3.2 Operating the User Interface for details on navigating the DCM menu system. b. See section Setting the Calibration Mode for details on verifying and changing the calibration mode. 4. Navigate to the MULTCAL sub-menu at menu address 2.3 and enter the sub-menu by pressing ENTER. 5. Add the new calibration point by following the procedure indicated in section Adding a Calibration Point. 6. Press and hold the BACK button for 5 seconds to return to the meter display. The H2O cut should read the entered water cut percentage. 28
