6 SECTION 1 - OIW-EX SERIES USER HANDBOOK INTRODUCTION This User handbook provides user information on how to use and configure the Advanced Sensors Ltd OIW-EX Series of Oil in Water Monitor Probe Systems. NOTE: This handbook as description of both describes both single and dual probe systems The system is designed to monitor the residual hydrocarbon content of pipelines carrying produced water at oil processing facilities etc. The OIW-EX Series of Oil in Water Monitor Systems uses laser radiation to energise the contents of the measurement chamber with an incident optical wavelength. A sensitive tuned detector at a different wavelength is then used to measure the stimulated fluorescence value. This fluorescence value is used to determine the proportion of hydrocarbons within the chamber. To overcome the problem of contamination of the optical path a proprietary self-cleaning technique has been incorporated. The cleaning process is user-configurable to accommodate a wide variation of environmental conditions. The equipment has a user friendly windows based display providing a wealth of information. Industry standard outputs include a 4-20 ma output as a measurement of oil content over a provisionable range, an RS-232 data output and an Ethernet port over which the user can either receive data, or remotely control the unit. The equipment is designed for installation in potentially explosive atmospheres and is certified to ATEX Directive (94/9/EC) Ex ll 2 G Ex d/de llb T4. CAUTION: This manual describes the operation and use of the unit NOT the installation. Ensure that the unit has been correctly installed in line with the In-Line Probe Installation Handbook (OIW-HBO-0012) prior to use.

9 Explosion Safety 1. The equipment is contained within a flameproof enclosure. To maintain the certification of this unit, the enclosure must not be damaged and the integrity of this is only intact if the status of the equipment as manufactured is maintained. No parts must be replaced, modified or substituted without reference to the manufacturer or their representative. 2. If any physical damage occurs to the sealed enclosure, glazed window or connection glands, then the power must be removed immediately and the manufacturer or their representative contacted for servicing. 3. The enclosure must be grounded via the external earth point provided, using an earth conductor meeting the local authority electrical regulations. 4. There are no user-serviceable parts within the unit; there should be no requirement for the door to be opened with power applied other than for installation and servicing. All servicing, installation and repairs must be carried out by the manufacturer or their representative. Any unauthorized repairs or modifications will not be under-written by the manufacturer. In certain environments the equipment may present a potential source of ignition when the enclosure is opened whilst powered; procedures appropriate to local site hot working must be adhered to. When closed, all 14 of the cap-head bolts around the periphery of the door must be set to a torque of 30 Nm. 5. All unused ports in the base of the enclosure must have an EExd approved brass M25 plug fitted. The torque setting for these plugs is 33 Nm Electrical Safety There are two variants of the system which are designed to operate off either a nominal 110VAC or 220VAC supply. These conform to EN Part 1. It is the responsibility of the installer to ensure compliance with the regional requirements for electrical safety regarding the provision of a compliant earth, earth bonding, adjacent electrical isolation and circuit protection. NOTE: Ensure the correct voltage supply is available on site before commencing installation Optical Safety The system uses a Class 3R laser as part of its measurement process. The light from this source is contained within the measurement chamber and is safe during normal operation. WARNING: Power should not be applied when the unit is in a disassembled state Audio Safety The system uses ultrasonic cleaning technology, which will operate periodically and conforms to EN Part 1. WARNING: When the ultrasonic device is in operation the average sound level may exceed safe levels, therefore suitable ear defenders must be worn and recognised signs posted to identify the potential hazard.

10 SECTION 2 - OVERVIEW OF OPERATION The OIW User Handbook OIW-HBO-0002, with the Measurement Cycle with the standard side-stream Configuration. Figure 1 below shows the Measurement Cycle of the OIW In-Line Probe. The Measurement Cycle with the OIW In-Line Probe is greatly simplified compared with the Standard OIW-EX Series as there are no valves to control as there would be in a Side-Stream configuration. Figure 1: OIW-EX100P and 1000P In-Line Probe Measurement Cycle Page 9 of 41

11 2.1 - MAIN WINDOW In Figure 2 below the Main Window is shown with a representation of the measurement cycle of an OIW-EX1000P. In this example, the Measurement Cycle field shows that OIW-EX1000P will measure for 1 hr, ( ) then clean for 20 seconds ( ): Figure 2: OIW-EX Main Window Page 10 of 41

12 2.2 - DISPLAY PREFERENCES Users can change screen configurations to suit their own requirement using the circled buttons in the examples below: Page 11 of 41

13 SECTION 3 - BASIC SOFTWARE INTERFACE OIW-EX SERIES OPERATING SYSTEM The OIW-EX Series of monitors runs on a standard Windows XP Pro user operating system. This manual assumes that users have a basic competence in using Windows XP. In everyday use the system requires minimal access to Windows XP. It is primarily used to gain access to the data logs stored on the hard drive STARTING THE OIW-EX SERIES On completion of the installation the system is ready to be turned on. The power up sequence takes approximately 3 minutes. During this time a variety of system level message are displayed on the screen (no user action is required). The Windows XP operating system starting message will appear, followed by the OIW-EX unit s start-up window, e.g.: Figure 3: OIW-EX Start-up Window NOTE: During power-up some information will be displayed rotated through 90o. This is normal operation and will orientate correctly on completion. When the OIW software starts it will automatically detect the hardware configuration and will indicate the model type in the header bar of the window, as highlighted in the example below: Page 12 of 41

14 3.3 - CONTROLLING THE OIW SOFTWARE WINDOW As can be seen the OIW control software is based on a standard Windows XP interface and the following control buttons are available in the upper right-hand corner: = Minimize = Reduce in size = Maximize = Exit The software starts up in full screen and should be left that way for standard operation. It can be minimised or reduced in size when the user wishes to perform routine admin tasks such as backing up the data log files etc. The software will continue to function during reduced or minimised states. To prevent the user from accidentally minimising or exiting the unit while the measurement cycle is running the control buttons are hidden as shown below in Figures 4 and 5: Figure 4: Control Buttons (Application Stopped) Figure 5: Control Buttons (Application Running) NOTE: When the unit in running the OIW software window can still be dragged across the screen. Page 13 of 41

15 3.4 - EXITING THE OIW SOFTWARE WINDOW When the measurement cycle is stopped and the control icons are visible the user can exit the OIW software by clicking the exit button. To avoid accidental and/or unauthorised exiting of the software, a warning box will appear in the centre of the screen when the exit button is clicked, as shown below in Figure 6. This box will prompt the user for the admin password. Figure 6: Exit Confirmation box If the incorrect password is entered then a system log will be generated highlighting an exit attempt has failed. If the correct password is entered then a system log will be generated highlighting that the OIW software has shutdown normally. While the OIW unit has been designed to handle sudden shutdown i.e. the unit is powered down immediately, exiting the software in this way ensures that there is traceability of the user s actions. CAUTION: 1. Unless maintenance is being carried out by authorized personnel there is no requirement for the software to be exited. 2. If there is any concern about normal operation of the unit, the window should be shut down and the unit powered down at the main power isolation point. Page 14 of 41

16 3.5 - SOFTWARE PANEL DESCRIPTIONS As can be seen in Figure 2 on page 14, the software is split into three screen panels. This section provides details on each panel. It also describes the admin panel which is visible when a user logs in via the admin password Feedback Display Area (Top Panel) This panel provides the user with feedback on the operation of the system and an example can be seen below in Figure 7: Details are shown below: Figure 7: Feedback Display Area PPM display Status display Alarm Indicators System Data Display PPM Average Display This large blue window area provides the user with the PPM reading. For readings from 0 ppm to 49999, the display will be to one decimal place and for readings from 100 to the upper limit the display will be a whole number. The PPM reading will normally be displayed in black text. However, at the end of the measuring cycle it will turn blue for three seconds to highlight that the new average measured value has been calculated. If the PPM level exceeds the upper calibrated PPM limit then the PPM reading will turn red and display only the upper limit. This smaller blue window area provides details of the current state and operation of the system. NOTE: In normal operation the text in this area will be in BLACK, however when the unit has been manually stopped the text will alternately flash red and white. These indicators display the alarm status summary and for the Syslog function also provide a means or acknowledging and clearing the alarms. For more details on alarms, please refer to pages This area is known as the System Data area. The system clock is displayed as standard. NOTE: The time displayed in the system display area is the time set in the Windows XP operating system. This boxed section provides the user with some level of at a glance historical data, e.g. the average PPM values for today and yesterday. Please refer to Section for more details. Page 15 of 41

17 User Alarms There are two types of alarm condition: Alarms generated as a result of PPM thresholds being exceeded. Alarms generated as a result of System Logs being generated. Each of these alarm conditions is represented by a multi-function button on the top panel just below the PPM legend PPM Alarms With no alarm conditions met, the ppm Alarm button will be displayed as shown below in Figure 12, i.e. with a grey background and the text No PPM Alarms on the button. When in this state moving the mouse over or selecting this button will have no effect. Figure 8: No PPM alarm For explanation purposes th ppm alarm trigger for Probe 1 has be set to 20 ppm. As can be seen above in Figure 12, with the ppm level below this trigger valve the ppm alarm button continues to display No PPM Alarms. However, if the ppm level rises above 20 ppm then the button will turn red and the text will highlight the alarm condition by changing to read PPM Alarm Probe 1 as shown below in Figure 9: Figure 9: PPM Alarm Level Exceeded Page 16 of 41

18 Should the ppm level exceed the maximum calibrated ppm limit for the current oil type (the number next to the heading Limit in this case 500 ppm) then the button below the graph display will change to red and the text will read ppm Out Of Range as shown in the example below (for 2x probes) in Figure 10: Figure 10: PPM Alarm Out Of Range Indications NOTE: As can be seen above when the ppm Out of Range alarm is raised the PPM reading will change to red and will continue to display the maximum calibrated limit even if the florescence value continues to rise this is done as any reading beyond this calibrated limit is not accurate. If the ppm alarm trigger level is set to zero then the No ppm > xx alarm will be raised. Only ppm Out of Range will be raised. Page 17 of 41

19 System Log Alarms System logs (SysLog for short) represent a record of events that have occurred during the operation of the unit. For information on system logs, please refer to the Data Logging Handbook (OIW-HBO-0003). As with the ppm alarms with no alarm conditions met the SysLog Alarm button will be displayed as shown below in Figure 11, below left, i.e. with a grey background and the text No SysLog Alarm on the button. When in this state moving the mouse over or selecting this button will have no effect. However, once a system log has been recorded the button will turn red, as shown below in Figure 11, below right, and the text will change to SysLog Updated highlighted in red, to indicate to the user that a new system log has been added to the system log file. Figure 11: SysLog alarms (No alarm on left, alarm on right) NOTE: The SysLog may have been updated as a result of one or more alarms Acknowledging and Clearing Alarms As mentioned previously, when either of the alarm buttons below the graph display is alarm free they have no function. However, when an alarm has been raised the button associated with that alarm will turn red (see Figure 12, left below). A red alarm button represents an unacknowledged alarm condition. If the user now clicks on the red button the button will change to amber see Figure 12, right below). An amber button represents an acknowledged alarm. If the user clicks on an amber alarm button the alarm button will be cleared and will return to the no alarm state. Figure 12: Alarm states (Unacknowledged on left, Acknowledged on right) If an alarm is acknowledged (amber) and continues to occur then it will not return to the unacknowledged (red) state. However, if the alarm is cleared (clicked while amber) and the alarm condition is still present then a fresh alarm will be raised returning to the unacknowledged (red) state. It is therefore advisable to acknowledge an alarm as soon as one is noticed, but not to clear an alarm until the alarm condition is clear. SysLog alarms operate differently in that if in the acknowledged (amber) state a different system log is raised then the button will return to the unacknowledged state to indicate that a new type of alarm has occurred. Page 18 of 41

20 Alarm Details Every time an alarm is raised, acknowledged or cleared this information is stored in the data log (please refer to the Data Logging Handbook (OIW-HBO-0003) for more information. In this way there is complete traceability of what is happening. In addition to this long term traceability the user can place the mouse over the button (without clicking the button) and a message box will appear between the upper and middle panels. This message box will provide the user with quick reference to when and what alarm was raised. Figure 14 below shows an example of this. When the user returns to the OIW at 15:41:25 they notice that a PPM alarm has been raised for Probe 1. When they place the mouse over the ppm alarm button the alarm message box appears. The message box indicates that at 12:41:55 the ppm level exceeded 15 ppm. Having seen the alarm the user can acknowledge the alarm by now clicking the alarm button and the button will now turn to amber. With the button in the acknowledged (amber) state if a second user were to view the screen they would be aware that this alarm has been seen. If the mouse is now placed over alarm button (see Figure 15 below) additional information is available, indicating not only what time the alarm was raised (i.e. 15:41:25), but also what time the alarm was acknowledged ( i.e.15:42:06). In the example below, the ppm value is still above 20 ppm so if the user clears this alarm (clicks on the amber alarm button) a fresh alarm will be raised. It is therefore best to leave the alarm at acknowledged (amber) until action has been taken to reduce the ppm level below the trigger level. System logs differ in that if other alarms are raised before the first is cleared then the alarm details box will indicate that other logs have been made by displaying Other Logs in the message text. Figure 13: Alarm Raised display Figure 14: Alarm Acknowledged display Page 19 of 41

21 Laser Life Warning The system monitors the life of the internal laser and when the laser life drops below 28 days of useful life the system displays a message in the black background area between the lower panel and the graph, as shown below in Figure 15: Figure 15: Display as laser nears end of life This display will count down as the laser is used until the lasers life expectancy has expired. At this point the message will change to that shown below in Figure 16. NOTE: The unit will continue to operate, but the user is advised to contact the manufacturer for a service check. Figure 16: Display when Lasers recommended life has expired NOTE: The laser life count is based on the number of days the laser has been in use, which is not necessarily the same period the system has been in use. Page 20 of 41

22 Graph Display Area (Middle Panel) The graph panel is the central panel on the screen and an example is shown below in Figure 17. This panel provides a graphical display of the PPM readings. The PPM Reading scale can be changed when the user is logged in for values in the range 1 ppm to 50,000 ppm. The time scale can also be changed when the user is logged in for the following values: 9 minutes 1.5 hours 6 hours 24 hours Figure 17: Graph Display Panel Area Page 21 of 41

23 Configuration Settings and Login Area (Lower Panel) This lower panel allows the user to view key configuration data (the details of this information as well as details on how to change them is explained in the following sections). In addition to displaying information, users can manually Start & Stop the measurement cycle ( ). Please refer to Section for further inf Figure 18: Lower Configuration and Login Panel (shown in Operating View) The lower panel also displays the Serial Number of the unit for data logging referencing ( ). This is factory configured to coincide with the hardware serial number of the system and correlates to the number of the door of the OIW unit. The current software version is displayed at ( ) and it is also recorded in the data logs. During normal operation none of the configuration settings are available. The Take Spectra button ( 5) is used to obtain a spectral representation of the PPM measurements which will be displayed on the Middle Panel. NOTE: The Take Spectra button can be found on the bottom left of all dialog boxes. To change any values the user must login by entering the Admin Password in the white box on the lower panel ( ), then clicking the Login button below the box. For security, as the password is entered * is displayed in place of each character typed. NOTE: If an incorrect password is entered more than three times then a log will be written to the system log file and (if enabled) an alarm will be raised. When the user is logged-in, all data fields can be seen. These are organised into the functional groups of Control Options, Ultrasonic Interface, Oil Calibration Settings and Configuration Options, e.g. Figure 19: Configuration Panel in Admin view (OIW EX1000P2) Page 22 of 41

24 Measurement Cycle Timing Configuration The measurement cycle data can be found on the left-hand side of the Lower Panel when in normal operational mode, e.g.: Figure 20: Measurement Cycle (Flow in Progress) NOTE: The display will change based on individual configurations. Page 23 of 41

25 Manual Control Manual control enables a user to start and stop the measurement cycle. It is accessible to all users and does not require a login access Start and Stop At power up the Manual Control button will appear in the bottom-right of the bottom panel, e.g.: When the Start button is clicked, the unit will start from the measurement cycle as defined in Section and the button changes to Stop, e.g.: Clicking on Stop will halt the current measurement cycle; the display will return to the start state and will indicate CYCLE STOPPED (see NOTE below). NOTE: In normal operation the text in the display area is BLACK, however when the unit has been manually stopped the text will flash RED and WHITE Saving Changes Any changes made in this view will take effect immediately and allow the user to see the result of these changes. However, these changes will not be stored for later use until the Save Changes & Logout button shown below is clicked: NOTE: If the unit is powered down or the OIW Software shutdown after changes have been made, but before the changes have been saved then these changes will be lost. Page 24 of 41

26 3.6 - CONTROL OPTIONS This dialog box allows users to set display and activation parameters as detailed in the table underneath. The options available are as follows: Figure 21: Control Options dialog box (OIW EX1000P2) Graph Display Settings Simulation Enabled Probe Display Toggle Trigger Tune Cycle This allows you to plot either the Trending or the Measured value and to change the axes of the Graph. In addition guidelines, in purple or green, may be drawn on the graph as a visual guide. This option facilitates commissioning and diagnostics and allows the user to set the PPM value, temperature or florescence settings. This selection can only be used while in the admin view. The default state at login is Simulation Enabled not checked meaning the actual values are being used and simulation is off. If the user has Simulation Enabled checked and logs-out, the simulation will revert to actual; i.e. simulation settings are not saved and only remain in force while a maintenance user is logged-in. This can be useful in calibrating the 4-2 0mA e.g. the user can set the PPM value to 0 and then to 100 ppm and ensure that 4 ma and 20 ma respectively are displayed. This feature is used during test and setup and only permits whole numbers to be entered. NOTE: When the PPM is simulated the displayed Flu value should be ignored as the system does not re-calculate the Flu value. However when Flu or Temp are simulated the displayed PPM value will be the calculated value resulting from the simulated value set. This allows users to select which probe or combination of probe information is to be displayed on the Middle Panel. This allows users to carry out an Auto Tune at the end of a measurement cycle. Page 25 of 41

27 3.7 - ULTRASONIC INTERFACE NOTE: The information in this section is for reference only. The control and configuration of the ultrasonic unit is only to be undertaken by or supervised by Advanced Sensors Ltd. Figure 22: Ultrasonic Interface dialog box This dialog box allows you to view the current status of the Ultrasonics. These controls will assist with the remote diagnosis of the Ultrasonics under the close guidance of Advanced Sensors. Page 26 of 41

28 3.8 - OIL CALIBRATION SETTINGS The options available are as follows: Gain Control Offset Control Flu Reading Spectrometer Standard Creation This allows you set the gain of the Sensor in the OIW Monitor. This is not normally changed after calibration has been completed This allows you set the offset of the Sensor in the OIW Monitor. This is not normally changed after calibration has been completed. This show the current Flu, Fluorescence which is also displayed in the top right hand part of the Top Panel of the Main Window. Please refer to the Spectrometer Handbook (OIW-HBO-0005) for further details. Page 27 of 41

29 3.9 - GENERAL CONFIGURATION OPTIONS SOFTWARE INTERFACE The following relates to OIW-EX Series of systems with software version The bottom third of the OIW monitor software is given over to the Configuration Tabs when you are logged in (please refer to Section for details on how to log in). When you log in for the first time the OIW monitor software shows the General Settings tab. Subsequent logins will show the last tab that was used. The tabs use the standard Windows tab convention for operation and each dialog box will be described as shown to a logged in user. NOTE: The current user is identified by a number displayed at the bottom-left of each dialog box General Configuration Options (System Settings) The System Settings dialog box is shown below in Figure 23 and the options are described in the table underneath: Figure 23: General Configuration System Settings dialog box 20mA Value Network Controller Access Active Probes Display Averaging Custom Tag Allows the user to select the PPM reading which will give full range at 20mA. As can be seen above in Figure 23, the default is set to 50ppm for 20mA but it can be adjusted via the drop down box. This allows the OIW Monitor, in conjunction with other Advanced Sensors technologies, e.g. to send SMS text messages and eimails, Please refer to the Advanced Sensors Remote Access Handbook (OIW-HBO-0004) for further information. Selects which probe(s) are to be used for measurement. The PPM reading by default is not averaged and will be displayed on a second by second basis. However this can lead to distracting jumps in readings from time to time. To avoid this, the Display Average selection can be set to display the average PPM value over a selection of time periods as below. This selection is made in the Admin view. NOTE: Display Averaging affects the PPM reading on the screen and on the 4-20 ma line, but does not affect the PPM reading sent to the data log file and does not alter the Flu reading on the system display area or the Flu reading within the file. Allows a user to insert a custom text file which will be displayed on the Main Window underneath the serial number and software information. Page 28 of 41

30 General Configuration Options (Display) The Display dialog allows the user to select the Temperature to be displayed on the as either C or F, e.g.: Figure 24: General Configuration Display dialog box There are also an option to show average readings of PPM over a 24 hr period and this is selected from the drop-down menu in the Additional Data Displayed section, e.g.: The average readings will then be displayed on the top panel, e.g.: General Configuration (Power Up) This dialog box allows users to set the OIW monitor to be re-started in a specified state after power has been re-stored following a power failure. Page 29 of 41

31 General Configuration (Custom Log Files) The Custom Log Files dialog box allows users to choose whether to write a custom log file in addition to the standard OIW data file and to choose the content of those Custom Log Files, e.g.: To enable the saving of Custom data, simply check the Enable Custom Log Files box and the boxes for those data parameters you wish to record. The Data Log Frequency selection allows you to choose to save a day s data in one or two files. A single OIW data file will save a data entry for each of the 86,400 seconds in day. Two files may be useful if you are running older versions of Excel and other mathematical analyses programs that are limited to 65,000 data points General Configuration (Password Control) This allows the configuration of up to seven unique passwords (User No. 0 through to User No. 6): NOTE: This dialog box cannot be accessed in Limited User mode.

32 SCHEDULE CONFIGURATION Measurement Cycle This allows you set the duration of each of the phases of operation of the OIW Monitor. Figure 25: Measurement Cycle dialog box Spectrometer This allows control of the Spectrometer. Please refer to the Spectrometer Handbook (OIW-HBO-0005) for details of the Spectrometer. Page 31 of 41

33 ALARM CONFIGURATION PPM Alarms The options available for users to change are as follows: Figure 26: PPM Alarms dialog box Enable Alarm Threshold 1 Enable Alarm Threshold 2 Enable Alarm Clearing Alarm Persistance Trigger External (H/W) Alarm for Probe 1 Trigger External (H/W) Alarm for Probe 2 Allows the user to select a PPM reading at which the alarm will indicate on the Main Window. Allows the user to select another PPM reading at which the alarm will indicate on the Main Window this figure must be higher than Threshold 1. When the PPM drops below the figures set in the PPM Alarm Clearing Threshold section for the period of time shown in he Clearing Persistence section, he alarm will be cleared. Allows users to set a time period before alarms are raised. When the PPM goes above the level set for PPM Alarm Threshold 1, a dry contact in the analyser will close if this is selected. This can be used to activate an external device, e.g. light bulb, valve, etc. When the PPM goes above the level set for PPM Alarm Threshold 2, a dry contact in the analyser will close if this is selected. This can be used to activate an external device, e.g. light bulb, valve, etc. Page 32 of 41

34 System Alarms The options available for users to change are as follows: Figure 27: System Alarms dialog box Enable System Log Alarms Exclude File System Alarms Trigger External (H/W) Alarm Output Enable System Log Alarms controls whether System Alarms are registered or not. Once the Enable System Log Alarms has been checked the System Log Alarms controls become available to you to adjust. When this option is selected, any file system errors will not be created. This allows files to be moved off the system without raising alarms. When a system alarm is present, a dry contact in the analyser will close if this is selected. This can be used to activate an external device, e.g. light bulb, valve, etc. Page 33 of 41

35 CONFIGURATION Figure 28: The Tab The 1+1 configuration consists of two OIW analyzers working in conjunction. One analyzer acts as the Master and the other as a Slave or Back-up. Should there be a failure with the Master analyzer, e.g. power failure, the Slave or Back-up OIW analyzer will start to monitor. Enable 1+1 Protection This Unit is Master Master and Slave IP Addressees Port Min - Recovery Time Allows users to disable 1+1 protection at any time. Only one of the two can act as the Master and the checkbox This Unit is Master should only be checked on the Master unit. The IP Address for the Master and Slave must be unique with respect to each other and with respect to other computers on the network. The Port number must be set as instructed by Advanced Sensors. The Min - Recovery Time is the number of minutes after a failure when the Slave analyzer takes over. Page 34 of 41

36 ULTRASONIC CONFIGURATION Ultrasonic Settings This dialog box allows users to set-up certain parameters for the Ultrasonic cleaing system. Figure 29: Ultrasonic Settings dialog box The options are described below: Ultrasonic Disable Probe Cleaning Frequency Cleaning Settings This allows the automatically disabling of the ultrasonics when the water temperature is at a specified threshold. This is automatically selected by the Auto Tuning feature (see next page for details) to ensure optimum frequency for the Ultrasonics cleaning. This allows users to fine-tune power levels and timings for the Ultrasonic cleaning cycle. NOTE: Cleaning Settings cannot be accessed in Limited or Standard User modes. Page 35 of 41

37 Auto Tuning This dialog box allows additional parameters to be set-up for the Ultrasonic cleaning system. The options are described below: Figure 30: Auto Tuning dialog box Probe Auto Tuning Settings (Probe 1 & 2) Percentage Sensitivity Frequency Offset This is the range of frequencies used during the Auto Tune cycle (normally set at the factory). This is factory preset. This is factory preset. NOTE: This dialog cannot be accessed in Limited or Standard User modes Factory US Settings These are preset in the factory and cannot be altered NOTE: This dialog cannot be accessed in Limited or Standard User modes.

38 OIL TYPE CONFIGURATION The options are described below: Figure 31: Oil Type Configuration(Oil Settings) window Set 1 Set 4 (Coefficient data) Threshold Load Oil Type File Create New These are the coefficients that map between the Fluorescence and the PPM reading. These values are read from the Oil Type File. Calibration curve limit values. This allows users to load the definition of an Oil Type from a list. Please refer to the next 2 pages for details of Oil Types Selection The current oil type is displayed in the area at the bottom entitled Current Oil Type File. This allows you to load the definition of an Oil Type. NOTE: For details of the Spectrometer Settings & Spectrometer Mask Settings, please refer to the Spectrometer Handbook (OIW-HBO-0005).

39 Oil Type General Information The system measures the fluorescence of oil however, each oil source will fluoresce with varying characteristics; consequently the system must be calibrated for each oil species. The primary characteristics of each oil type can however be captured in a series of settings. These settings are stored within a file in a folder named OIWOilTypes on the OIW s hard drive. Each oil type, and in turn each oil type file, is characterised by four main areas of data: Oil coefficients (not to be altered once generated by Advanced Sensors Ltd). Temperature coefficients. Offset values. Offset values. These will now be described in some detail, starting with how to select an oil type (which includes the fixed oil coefficients) Oil Type Selection The location of the OIWOilTypes folder is at the top level of the main hard drive, is shown below. Note that the hard drive letter may vary from system to system (in the example shown below in Figure 32 it is C :): Figure 32: Location of OIWOilTypes directory typical on hard drive Within this directory is a file for each of the different oil species specified. The standard library of oil species files will be supplied by Advanced Sensors Ltd following calibration. Any oil species not in the library can be characterised and added to the library upon supply of a customer sample Page 38 of 41

40 Figure 33: View of OilType files NOTE: As shown above, each oil type file is a standard Comma Separated Values (CSV) file, but neither the file name nor the contents should be altered by the user from the windows interface. If the OIW software cannot find the configured oil type file or if it cannot read it then the OIW software will log an error to the system log and shut down. Oil Type selection is be accessed from the admin view, e.g.: Figure 34: Admin View showing Oil Type button Click on the Oil Type button then the Load Oil Type File button on the Oil Settings dialog box and list of all oil types on the system should appear, e.g.: To change the oil type simple double click on an oil type listed (or click once on the oil type name and then click the Load button. The system is now ready to measure that type of oil. The bottom panel will display the oil type being monitored, e.g.: Page 39 of 41

41 Integration Time Offset Control Overview The offset value enables an offset to be applied to the PPM output. For example looking at the results in the graph shown below in Figure 35, if the lab results are reading consistently higher than the system results then an offset can be applied to the system output to compensate for this. Figure 35: Offset Graph Similarly, the fine gain can be applied if it is identified that as the fluorescence increases so does the PPM value, as shown below in Figure 36: Figure 36: Gain Graph Page 40 of 41
