8. 8 I-Test Overview I-Test is suitable for small and large fleet users alike and offers simple gas monitor bump testing and calibration, including full data management. I-Test versions are available for both Gas-Pro and T4. I-Test can quickly and simply undertake testing and store data either locally to the I-Test or allow download to a PC or USB memory stick, including download and storage of gas monitor log files. I-Test provides data management allowing easy reporting of bump test and calibration results across the fleet. I-Test can also offer simple updating of gas monitor details such as alarm levels with updates being managed within the fleet during regular bump tests. Using minimal gas and managing sequencing the I-Test ensures sensors are gassed correctly every time. Suitability I-Test is suitable for testing and calibrating Gas-Pro and T4 units fitted with one or more of the following sensors: Oxygen, Carbon Monoxide, Hydrogen Sulphide, Carbon Dioxide IR or Methane Pellistor. I-Test will be functional with Gas-Pro units configured with firmware versions 1V09 & 2V06 onwards. The firmware version of Gas-Pro can be seen as part of the start up screens when the monitor is powered up. I-Test is functional with firmware versions of T4 from 1V01 upwards. I-Test Functional Overview I-Test offers the following main functions and features for the testing, calibration and management of gas monitors. Speedy bump A speedy bump will test the monitor sensors to the first alarm level. Gas is presented across/over the sensors for a designated time (dependent on sensor gas type) during which alarm level one should be activated. This will be deemed a pass if the monitor goes into alarm or a failure if the monitor does not go into alarm.

9. 9 Smart bump A smart bump will test that the gas monitor responds correctly to a specified level of test gas. Gas is passed over/across the sensors and a predicted response is expected within a time window dependant on the sensor response time. The test is passed if the gas level indicated by the monitor is within pre-specified tolerance limits within this time window. Calibration I-Test can be configured to undertake the routine service calibration of a gas monitor. In this instance a calibration would be completed without a bump test being required. I-Test is suitable for routine service calibration of monitors. If a new sensor has been fitted to the monitor then Portables-Pro should be used to calibrate the monitor not I-Test, otherwise incorrect calibration may occur. Calibration after bump fail If any sensor fails a speedy bump or smart bump, I-Test can be configured to perform a ‘calibration after bump fail, immediately after the bump test failure. Gas Monitor Field Configuration During normal operation, whilst performing gas testing, I-Test can be configured to change aspects of the inserted gas monitor configuration, such as sensor alarm levels as well as other aspects of configuration. Gas Monitor Log Download During normal operation I-Test can be configured to download either event logs and/or data logs from the monitor under test. These log files are stored locally and can be extracted either via PC or USB flash drive. Data Management & Reporting I-Test in conjunction with its PC Application, I-Test Manager, can be utilised for full data management of the bump test and calibration data. I-Test Manager allows the user to specify exception reports to quickly identify instruments, for example, that have not been bump tested or failed bump test. I-Test Manager will also allow a user to upload and view monitor log files from the I-Test. Bump test and calibration reports can also be created, printed and stored.

22. 22 X Click on Next and follow the on-screen instructions and the following installation screen will be shown. Figure 12: ATEX or UL Region screen X I-Test Manager needs to be configured for the type of I-Test purchased, either ATEX region or UL region compatible.

Speedy Bump: Select this option to undertake a speedy bump on all sensors when the gas monitor is inserted into I-Test. A speedy bump will test the gas monitor sensors to the first alarm level. Smart Bump: (Gas-Pro only) Select this option to undertake smart bump on all sensors when the gas monitor is inserted into I-Test. A smart bump will test that the gas monitor responds correctly to a specified level of test gas within a predefined time window. These parameters are set in the Inlet Configuration settings, see page 40 . i Only one type of bump test can be selected, if speedy bump test is selected then smart bump will be disabled and vice versa. I-Test will not check calibration before undertaking a bump test and will continue to bump test a gas monitor if calibration is due on a specific sensor (unless the Calibrate if Expired option is selected). Calibration: I-Test offers thee calibration options dependant upon user requirements, Standalone Calibration, Calibration after Bump Test Fail and Calibrate if Expired.

37. 37 Standalone Calibration: This option should be selected if I-Test is to be configured to undertake only a calibration function, on the gas monitor inserted. This will be indicated in I-Test Manager by the text ‘(Stand alone)’ appearing after the Calibration option when selected. Standalone calibration will calibrate all sensors in the gas monitor, this will occur even if the sensor was not due a calibration. Standalone calibration cannot be selected when a speedy bump is selected. If standalone calibration is selected with smart bump this will change the functionality of the calibration process as described below in Bump Test Fail Calibration. Standalone calibration can be selected with Allow configuration, Download event log, and Download event log. Bump Test Fail Calibration: This option should be selected if there is a requirement to calibrate a sensor, should it fail a speedy bump or a smart bump test. If Calibration and Speedy Bump or Smart Bump are selected together, I-Test will not perform a standalone calibration on any sensor that fails the selected bump test. This will be indicated in I-Test Manager by the text ‘(Bump Test Fail)’ appearing after the Calibration option when speedy bump or speedy bump or smart bump is also selected. Only sensors that fail the selected bump test will be calibrated, this will occur even if the sensor was not due a calibration. Bump Test Fail Calibration can be selected with Speedy Bump, Smart Bump, Calibrate if Expired, Allow configuration, Download monitor event log, and Download monitor data log. Calibrate if Expired: This option should be selected if it is required that a gas monitor whose calibration has expired, when inserted into I-Test should be automatically calibrated if an appropriate cylinder is attached. This will override a bump test action if configured and only a calibration will be undertaken.

Figure 54: Calibration summary report • Event Type • Overall Pass/Fail Result of Calibration • I-Test Serial Number • Print date of report

41. 41 Bump Test Due Increment: If I-Test undertakes a successful bump test on the inserted gas monitor the bump test due date will be incremented within the gas monitor. This will ensure the gas monitor alerts the user when the next bump test is due. Bump Test Due Increment is the increment in days that will be added to the current date in the gas monitor to indicate when the next bump test is due. When entering the actual gas value also enter the bump test due increment then click on update gas value. The entered value will be displayed in the Gases list. This option is only enabled if the selected cylinder is suitable for speedy bump or smart bump. Smart bump tolerance +/-: A smart bump will test that the inserted gas monitor sensors respond correctly to the applied level of gas. Smart bump will be deemed a pass if the sensors reach the applied level of gas with a given tolerance. This tolerance is the Smart bump tolerance and is a percentage band of the applied gas level. The gases previously defined in the cylinder will contain the Crowcon default smart bump tolerance. This can be seen in the Gases list under ‘Bump +/- %‘. If required this tolerance can be increased by entering a value in the Smart bump tolerance +/- field. This will be added to the default value. The minimum and maximum pass values for the smart bump test per sensor can be seen in the Gases list under ‘Min’ and ‘Max’ respectively. This option is only enabled if the selected cylinder is suitable for smart bump. i Actual gas values, expiry date & Lot number, bump test intermittent interval & bump test deviation can only be saved directly to an I-Test via the USB connector or to the database. If this configuration is to be saved to USB memory stick these values are not saved. 3.7.5 Field configuration During normal operation, whilst performing gas testing, I-Test can be configured to change aspects of the inserted gas monitor configuration, such as sensor alarm levels as well as other aspects of configuration. Field configuration defines the functionality of an instrument configuration file that can be uploaded to the gas monitor via the I-Test. There are two main functional areas where gas monitor configuration can be changed; gas monitor and sensors. Gas monitor settings are specific to the specified type of gas monitor and sensor settings relate to specific gas sensors independent of gas monitor type.

44. 44 Action On Startup: This field determines the functionality of the gas monitor when powered up with regard to the built in ‘Clean air’ zero function. If it is required to change the Action on Startup setting on the gas monitor activate the Action on Startup tick box and from the drop down box select one of the following options: No action: No ‘Clean air’ zero action at startup. Confirm zero: This setting allows the ‘Clean air’ zero to be carried out at the user’s discretion. Always zero: This setting means a ‘Clean air’ zero will always be carried out at startup. Logging Interval: This field determines the interval at which the gas monitor will record gas readings to its internal log file. If it is required to change the logging interval activate the logging interval tick box and set the required time interval in seconds. Minimum interval 1 of second and maximum interval of 32400 seconds between log readings. Calibration Due Increment: If a gas monitor is configured to undertake either a Bump Test Fail Calibration or a Stand alone Calibration, and the calibration is successful, the calibration due date will be incremented within the gas monitor. The increment interval (in days) is preconfigured within the gas monitor at factory, typically 30 days. It is possible to change this increment by uploading a new configuration file to the gas monitor. Activate the Calibration Due Increment tick box and set the required interval in days (minimum 1, maximum 720) between calibrating the monitor i Once I-Test has been configured to apply a monitor field configuration file, it will continue to do this to each and every monitor inserted into I-Test. If it is required to stop the configuration update it is necessary to deselect the ‘Apply Changes On’ tick box and save this configuration to I-Test.

100. 100 4.4.1 Speedy bump Select this option to undertake a speedy bump on all sensors when the gas monitor is inserted into I-Test.

If the test is failed I-Test will display the following icon and the LED on the I-Test gas monitor pod will be illuminated red (see below). Figure 8: Result indications I-Test will also display the icon if I-Test was unable to perform the configured test. This may occur for example if a monitor is inserted with an unsupported sensor/gas fitment or if the attached cylinder does not contain a suitable test gas for a specific sensor type in the monitor . If the monitor is not correctly inserted in the gas monitor pod it may not be recognised by I-Test. This will be indicated by the I-Test gas monitor pod LED red and the icon flashing for a period of approximately 30 seconds. The monitor must be removed from the I-Test and reinserted. Note: If a monitor is inserted into I-Test with a specific sensor due bump test (not all sensors may be due a bump test on the same date) and the attached cylinder does not contain the required gas, I-Test will display the icon and not perform a bump test on any sensors. If a monitor is inserted into I-Test with a specific sensor(s) not due a bump test and the attached cylinder does not contain that required gas(s) but the cylinder does contain the gas for remaining sensors due a bump test. I-Test will continue to bump test the sensors due and will not bump test the sensor(s) not due. 1 3 M a y 2 0 1 3 1 1 : 1 8 : 4 2 I-T est 1 3 M a y 2 0 1 3 1 1 : 1 8 : 4 2 I-T est À

19. 19 2.5 Main menu status icons At certain times (e.g. after bump tests) a status icon À is displayed on the Main menu as shown in Figure 9 below. Figure 9: Status Icon These status icons have the following meanings: • Action successful • Action failed 2.6 Replacing an empty gas cylinder If a cylinder connected to the inlet is completely exhausted I-Test will recognised this and the icon will be displayed on the screen. It will be necessary to physically replace the cylinder and enter the new gas concentrations, Cylinder Lot Number, and Cylinder Expiry Date via either I-Test front panel (see page 97 and page 98 ) or via I-Test Manager (see page 40 and page 40 ). i If the cylinder was exhausted during a calibration the monitor may indicate a service fault which must be cleared. Remove the monitor from I-Test and cancel all fault indications. Once the cylinder has been replaced the monitor can then be reinserted and test can be repeated. i If I-Test detects an exhausted cylinder and the cylinder is physically changed, a new Cylinder Lot number and Cylinder Expiry Date must be entered. If this process is not followed, I-Test will not allow gas testing to continue and will indicate this on the screen. 2.7 I-Test Safe Shutdown If it is required to remove power from I-Test either by removing the power lead or switching off via the on/off push button then the safe shutdown process must be followed.

15. 15 2. Operating I-Test This section details how to operate I-Test to perform the desired testing after I-Test has been fully configured via I-Test Manager (see page 25 ) or via I-Test Front panel Keypad (see page 90 ). Ensure I-Test is installed correctly and that the test gas cylinder is attached as detailed on page 12 . i Before operating the I-Test it must be configured via I-Test Manager PC Application and must then be disconnected from the PC USB connection. If I-Test is not disconnected from the PC it will not operate. i Before a test can be undertaken ensure the I-Test display screen is showing the home screen. If the home screen is not shown the configured test will not be initiated. i Ensure the test gas cylinder connected to the inlet, has the same gas mix and concentration as configured in the I-Test (see page 40 or page 94 ). i When manufactured I-Test is configured with a default gas cylinder and a default expiry date. This expiry date must be changed to that of the actual cylinder to be attached or I-Test will not function correctly as it will report that the cylinder has expired. i To ensure accurate bump testing and calibration the purge inlet MUST be connected to fresh air. i When I-Test is initially powered it will perform a purge cycle for approximately 30 seconds, before I-Test can be used. 2.1 Gas Monitor Testing Overview Once I-Test has been configured to carry out a test or a sequence of tests, proceed as follows: X Ensure the I-Test is either fully charged and/or connected to a suitable power source (see page 14 ). X Ensure the I-Test is NOT connected to the PC via the USB socket. X Connect the required gas cylinder to the appropriate inlets (see page 12 ). X Ensure the purge inlet is connected to fresh air. X Ensure a suitable length of pipe that vents to outside air is connected to the exhaust outlet. X Turn the gas monitor on and wait for it to finish its start up routine. X Turn on I-Test and wait for the start up purge sequence to complete X Insert the gas monitor into I-Test (see page 16 ). X The configured test or test sequence will automatically be performed and I-T est will indicate the success or failure of the test (see page 18 ).

104. 104 4.4.4 Gas Monitor Log File Transfer to I-Test As part of a test sequence I-Test can be configured to transfer the gas monitor log files to I-Test. I-Test Manager offers the functionality to select if either the gas monitor event logs or gas monitor data logs are transferred to the I-Test, or both (see page 38 ). Once this selection has been made I-Test can be configured via the I-Test front panel to transfer the selected log files to I-Test. To transfer log files from the gas monitor to I-Test, proceed as follows: X From the Test Sequence screen use the arrow keys to navigate to the Log File Transfer icon then press OK to highlight the Log File Transfer icon À . X A box will now appear around the icon indicating that Log File Transfer function has been selected and this test will be performed if a gas monitor is inserted into the I-Test. I-Test will transfer log files from the monitor to I-Test as the last action of the test sequence. The progress screen Á will be displayed on I-Test as the log files are transferred. X Press to return to Test Settings screen and then press again to return to main menu screen. !

27. 27 Cross Calibration: This option should be selected when all the gas monitors to be bump tested or calibrated by an I-Test are not all configured with the same flammable gas sensor or if the target gas is not available for monitors containing C 5 H 12 , C 3 H 8 , C 4 H 10 sensors. For example if the fleet contains a mixture of monitors with CH 4 and C 3 H 8 sensors both requiring test by I-Test, then the cross calibration option should be selected when configuring the cylinder. This will allow both the CH 4 and C 3 H 8 gas monitors to undergo the desired bump or calibration test in the same I-Test unit. i If the cross calibration option is selected, cylinders must be configured with CH4 as the flammable gas. The concentration of CH4 must be 1.2% volume for ATEX/IECEx monitors and 1.5% volume for UL monitors. For a list of cylinders available from Crowcon please refer to Section 8 . The gas cylinder for cross calibration must have a tolerance no greater than 5%. If the Cross Calibration option is selected this will also allow gas monitors to be bump tested with non target gas in the same manner as described above for calibration. Note: T4 must only be calibrated with a cylinder containing CH4, the cross calibration option is not applicable for T4 and will not operate in a T4 configured I-Test. Gases: Click on a gas in the Gases list and then make a selection from the Gas drop down list, and enter the standard gas value in the Standard Value field. Dependant upon cylinder type selected the gas options are CH 4 , C 5 H 12 , C 3 H 8 , C 4 H 10 , CO, H 2 S, CO 2 & O 2 (see Appendix A: Allowable Cylinder Profiles ). Dependant upon the suitability option chosen, I-Test Manager will restrict the gas value entered to ensure the gas value is appropriate for the Suitability selected. When defining the standard value of the flammable gas selected, t he gas value must be entered in units of %volume. The saved value will be converted to %LEL for internal use in I-Test. Note: T4 must only be bump tested and calibrated with a cylinder containing CH 4 . A T4 configured I-Test will not perform the configured test if any other cylinder is connected to I-Test. X When the alterations have been made, click Update Gas. This will update the entry in the Gases list. X Repeat this process for each gas to be defined in the cylinder profile.
