SECTION 1 - OIW-EX SERIES USER HANDBOOK

1.1 - 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.

SECTION 3 - BASIC SOFTWARE INTERFACE

3.1 - 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.

3.2 - 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



U S E R M A N U A L


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



U S E R M A N U A L


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.

Figure 6: Exit Confirmation box

This box will prompt the user for the admin password.

• 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.

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.

3.5.1 - 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:

Figure 7: Feedback Display Area

Details are shown below:

1 PPM

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.

2 Status display

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.

3 Alarm

Indicators

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 21 – 25.

4 System

Data Display

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.

5 PPM

Average Display

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 3.9.2 for more details.

3.5.1.1 - 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.

3.5.1.1.1 - 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



U S E R M A N U A L


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



U S E R M A N U A L


3.5.1.1.2 - 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.

3.5.1.1.3 - 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



U S E R M A N U A L


3.5.1.1.4 - 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.

3.5.1.1.5 - 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.

3.5.2 - 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

3.5.3 - 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 3.5.3.2 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.

3.6 - CONTROL OPTIONS

This dialog box allows users to set display and activation parameters as detailed in the table underneath.

Figure 21: Control Options dialog box (OIW EX1000P2)

The options available are as follows:

Graph Display Settings

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.

Simulation Enabled

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.

Probe Display Toggle This allows users to select which probe or combination of probe information is to be

displayed on the Middle Panel.

Trigger Tune Cycle This allows users to carry out an Auto Tune at the end of a measurement cycle.

Display

Averaging

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.

Custom Tag Allows a user to insert a custom text file which will be displayed on the Main Window underneath the serial number and software information.

3.14.1 - 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).

3.14.2 - 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

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.:

3.14.3 - 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:
