    1. Complete?, and present to the customer for signature.

      Currently TP-00473-F2

    2. Create a Service Report

      This would already have been created prior to getting onsite.

    3. any draws

      Regarding Candida, you should also make certain to use drawer 7 as well to get the ramp rate values for TC2B2.

    4. Perform a Stress Test

      Currently it is only Bacteria

    5. make sure belt tensions

      Belt tensioning should be performed before alignments.

    6. Determine if Technical Service Bulletins (TSBs) are applicable to the instrument

      This really needs to be done before you even get onsite so you can order the parts you would need to complete the TSB. We don't carry everything all the time.

    7. Restart the instrument computer

      Before you restart the instrument, this would be a good time to Configure the T2 for testing. Otherwise you'll be waiting for ever for the instrument to come to a ready state.

    8. compliance mounts

      I've have yet to find a damaged Gripper compliance mount and the movement is not as easy to verify as the Pipettor. Do you think we could add pictures of what a damaged mount looks like?

    9. axis rails

      In some cases the rails themselves aren't aligned correctly and need to be loosened, realigned and then tightened to correct improper movement. There isn't a procedure for this that I am aware of.

    10. mounted properly

      Mounted properly means what? I think all we really try to verify is that the sensor and flag are not damaged and they engage each other correctly (flag is centered).

    11. Ensure all ports for the cables are correct

      Is the intent to verify all external ports are functional? 4 USB ports (can be verified with Barcode scanner or flash drives or the printer). The Ethernet connections can be verified with the laptop though I've never tried plugging into the rear port.

    12. Install the printer

      Can we reference the "current" printer used here? We actually don't have a true procedure for installing a printer and it can be ever changing as printer models are obsoleted. Perhaps there are generic steps for Windows (either 7 or 10) that can be referenced?

    13. MR Reader module

      I've had oil tubes left in this module from Manufacturing. Could we mention to check for this, just in case?

    14. External Printer

      Should we also mention the Standard T2Dx Service Kit (BOM) that needs to be ordered here?

    15. T2Candida 1.1 Cartridges

      We currently order the following:

      • 3-Candida cartridges
      • 3-Candida reagents
      • 4-Candida QCheck Pos
      • 2-Candida Qcheck Neg
      • 2-Bacteria cartridges
      • 1-Bacteria reagents
      • 1-Bacteria QCheck Neg
    16. T2Bacteria Cartridges

      Quantity is missing and what about Bacteria reagents and controls that may need to be cycled for customers interested in processing Bacteria samples?

    17. Decontaminate Tools and Teach Tools

      We also need to include Test Equipment (Voltmeter, Temp meter, etc.).

    18. five days

      Does this mean 5 full business days? I don't know if this information is necessary. I would hate to imply it's better to finish in 5 days then being thorough and taking as long as it takes to complete the install.

    1. Thermocycler Tuning

      What conditions (including specific errors) other than temperature instability warrant performing this procedure?

    2. there are ways to control which bank gets used

      What are the ways to control which bank is used?

    1. RampOverheadSecondsPerCycleForBacteria

      If the customer is not processing Bacteria tests, what is the recommended value for the Bacteria ramp rate?

    2. table below

      Again it's just easier to show (and use) the actual Search window data.

    3. Confirm that all banks pass

      What do we do if a bank(s) does not pass the criteria?

    4. table below

      Is there any chance to get a picture that actually shows the values in the Search area as we taught to locate it on our laptop?

    5. profile

      Since 1.5 software (and possibly before), this seems to be the default profile but it is always good to verify.

    6. Update the P and I values using the values recorded on the blue tag that shipped with the module.

      I don't think this information is on the blue tag but I could be wrong.

    7. BEFORE powering on the instrument

      Since the instrument is already powered off, I'm not clear how we are going to follow these instructions at this time.

    8. calibration values

      If you are referring to the P&I values, they should be defaulted to 11.0 and 0.75. What actually needs to be changed are the values in the Configurations folder for that particular bank. If not, whatever value is in the file will over right the value on board the module. As long as these values are correct before any verification other than temperature checks, it will be okay.

    9. T2Candida 1.1 Cartridges

      Regarding the quantity for Consumables, am I correct in assuming we are processing 5 controls now for Thermocycler verification? And yet only 4 cartridges and reagent trays are called out.

    1. For Service Procedures, I would like to see a Purpose statement (why and when you are using this procedure) and Tools/Supplies (specific to that procedure) where not already stated. I would also like to see a reference to placing the instrument into "Development mode" prior to performing the procedure and a reminder to take the instrument out of "Development mode". In addition, are we recommending to disable the upper enclosure fans/heaters when servicing the instrument with the power on? Also in some cases after replacing a module, the first time you power on a Communication error occurs for that module. The reason is the IP address for that module is incorrect. Can we add a statement to the beginning of the Service Procedures section on how to correct this in the event it occurs? Regarding Instrument Verification after module replacement(s), typically we are only required to process 4 controls (2-Neg, 2-Pos).. The PMT is solely for the Pipettor pump and Stress tests are usually used to validate any repair that doesn't influence result recovery.

    1. Record the following configuration values

      Just a reminder that this has to be done for all 4 banks.

    2. THIS MUST BE DONE BEFORE THE MAINCONTROLLER APPLICATION STARTS

      At what point does this actually occur during the power up sequence? Since the new Thermocycler should come with all the banks P&I values defaulted to 11.0/0.75, I don't think this procedure is necessary.

    1. Quantity

      Where do the quantity values come from for the Consumables? Does the 1-6 reference how many I might use per a specific procedure?

    1. The autotune sequence test will most likely fail. Allow the instrument to continue the autotuning until it passes. If the autotune takes longer than 12 hours to pass, contact T2 Support

      We should be waiting at least 12 hours for temperature equilibration before any attempt to Autotune. I think this should be performed during the Test the MR Reader section.

    2. Restart the Main Controller application

      This isn't necessary at this time until all settings have been properly updated, including gripper alignment. Assuming you are in Development mode, you wouldn't have to worry about the autotune sequence test failing either.

    3. Remove the MR Reader

      You would not have to remove the Right End Cap cover if you can access the NDX connector from the rear. This would be noticeable after removing the back panel.

    4. carefully lower the module into the T2Dx instrument.

      You need a reminder to feed the 5V power cable and NDX cable into the entry hole before lowering the module in place.

    5. Do not damage the thermistor when installing the MR Reader!

      Better to mention this before you start replacing the module. It could also be mentioned at the beginning of the entire procedure.

    1. Perform the following tests

      I believe controls are all that is required unless this is new.

    2. 37°C Incubator

      HVO

    3. 37C Incubator

      HVO

    4. 37°C Incubator

      You mean HVO.

    5. Update the HVO Configuration Values

      Updates would also include:

      • IP address (communication error if not correct)
      • Firmware
      • Offsets (Angle and Field Degrees)
    6. Once the modules warm up, a Self Test will occur.

      This would actually not be an issue in Development mode. Having to wait for the self testing to complete can be very time consuming and should be part of Verification.

    7. Lift the module up

      You have to be very careful not to damage the wiring for the belt break sensor and LED, located near the top and opposite of each other.

    8. four (4) screws

      Could be Hex or Philips. Probably just have to state "Remove 4 screws..."

    9. Manually move the Pipettor

      Simply reminding us to move the Pipettor should be good enough. To the right or left depends on the HVO.

    1. Change all settings back to the default:

      Same as I stated for Bacteria stress tests.

    2. set the following parameters

      Same as I stated for Bacteria stress tests.

    1. Change all settings back to the default

      And restart the application. Allow self-tests to complete.

    2. set the following parameters:

      This can also be done on the touchscreen. You need to restart the application either way for the changes to take affect.

    1. The number of required draws to run depends on the preceding service procedure

      Perhaps this could be mentioned in the beginning so you know how many test panels you need. I believe the installation requires 7 and a pump replacement requires 4.

    2. If bleach tubes are not present, place a 0.2mL tube into each bleach tube well and push both tubes fully down into the cartridge base

      What happens if we don't add these tubes?

    1. manually calculate

      I think all the current software out in the field gives you the value without needing to calculate it?

    2. From Baretail

      The picture should be the search window not the line by line log data.

    3. Using a service laptop, navigate to C://192.168.1.100/T2BiosystemsLogs

      Baretail should automatically take you to the most recent log file assuming you're attached to an instrument.

    1. Tilt case assembly to rest at an angle on designated cleaning area.

      It seems we have already removed the Lid at this point but I'm curious as to how I got it off? A picture and a suggestion would be useful. I also wonder if we should mark both the Case and Lid so we orient them back together correctly?

    2. Centrifuge Lid Removal

      When removing the Centrifuge, I have always left the Lid attached. Is the goal of this procedure to remove the Lid for cleaning purposes or to repair a Lid component?

    1. Gripper Assembly Replacement

      Gripper Robot v. Gripper Head. I only have replaced the Gripper Head so I can't really comment on the usefulness of this section. What does the part we are replacing here actually look like?

    1. As part of Pre-Maintenance Setup, I would suggest placing the instrument in "Development mode".

    2. Diagnose the instrument log files using the T2Dx Log Search Tool

      This section assumes I am well versed in log interpretation. I can't speak for everyone else but "logs analysis" continues to be an area I need improvement. Will there be a section in the new FSM to guide us in interpreting and resolving errors?

    3. Perform a Level 2 cleaning

      A level 2 cleaning includes all of a level 1 and the centrifuge. I understand why to do it now but remove the Level 2 reference. Otherwise, I tend to perform the Centrifuge first and then the rest of the instrument. By the time i'm done with the Centrifuge, the other modules are cold enough to clean.

    4. T2Dx 1.1 Instruments

      What are we doing about 1.0 instruments?

    5. Without removing draws

      I think the general consensus is to remove the drawers to clean all relevant sensors and guides. We can certainly help you with the procedure.

    6. Install the reassembled filter housing onto the top back of the instrument and secure with the two (2) mounting screws.

      Since we are going to verify heater function after the UV bulb replacement, perhaps we could wait to replace the cover until after the heater verification?

    7. The PM typically takes two days to perform

      Our goal is to complete the entire PM on day 1 and load controls. With the possible addition of TSBs and software upgrades, 2 full days + controls is not out of the question.

    1. Two things. I don't see the verification steps (perhaps they are somewhere else) and since there isn't power supplied to the lamp (lamp is off), do we really have to power off to replace it? I also prefer to use the Service UI to move the drawers.

  3. portal.t2biosystems.com portal.t2biosystems.com
    1. T2 Biosystems employs a B-3-IW method when cleaning.

      Later in the procedure the words "Dampen and Saturate" are used. How to we distinguish between the two? Also should there be a reference to swabs and their use?

    2. Decontaminate Tools and Teach Tools

      Is this new to use bleach on the teach tools? Last word was to only use alcohol.

    3. Use direct wetting (spray on) of 10% Bleach on solid surfaces

      Does this include prep areas and around the instrument? I was not aware we could do this.

    1. A suggestion to be completed before starting TSBs (or Robot Hardware verification) is to "Configure T2Dx Instrument for Testing" by updating the following: EnableDevelopmentMode, AutotuneDurationInHours, DesiredUvSoakTimeMinutes, EnableSelfTest. We would also want a reminder to set these back to their "normal" values. This can be done either via editing the MainController or on board.

    1. Perform the following tests

      Unless this is a new requirement, stress test and PMT are not required. Only controls.

    2. Check that all wells are within specification

      What is do be done if all the wells are not in spec?

    3. Remove the 37°C Incubator

      This procedure is only for 1.1 instruments. 1.0 instruments do not have the extra HVO and a different incubator module.

    4. 2.5mm Hex wrench

      Could be Philips screws

    5. Manually

      Perhaps it's me but it seems redundant to use "Manually" when there is no other option with the power off.

    1. install the 5 hex head screws

      Again, only 4 circles. How tight do we want to make these screws?

    2. remove the 5 hex

      I only see four orange circles.

    3. remove all 2mm hex head screws

      I've often wondered if there is a "best" manner in which to remove these screws? Where is the best starting and end point? We should also mention to make certain the Gripper is moved forward to avoid hitting the upper fan cover area of the panel?

    1. the bucket is centered with opening

      What do we do if the bucket is not centered?

    2. Update the Centrifuge Firmware and Settings

      As with all module replacements, there are times after powering on that a communication error occurs (20006) due to an incorrect IP address. Do we want to mention this here and with all module replacements?

    3. locate the blue tag that shipped with the replacement centrifuge

      Perhaps this would be better to state after removing the new centrifuge from the box?

    4. Should there be another step to instruct you to power on the instrument?

    5. visually inspect

      Inspect all wiring connections and conditions of hardware as Mark mentioned, not necessarily shipping related.

    6. Step 1.5, these screws may be Philips. Depends on age of instrument.

    7. two 3mm hex head screws.

      It seems newer instruments are now coming with 2.5mm screws.

    8. When powering off instrument, why was the "customer" option used instead of the "service" option?
