TECHNICAL SERVICE BULLETIN: TSB2015-007

1 TSB2015-007 Rev AA TECHNICAL SERVICE bulletin : TSB2015-007 To: Global SERVICE Organization, iChem VELOCITY and iRICELL Distributors From: Iris Diagnostics SERVICE and Support Date: 10 June 2015 Subject: STRIP PROVIDER MODULE (SPM) PART NUMBERS B39124 / 700-7200 / 700-7200S Instruments Affected: iChemVELOCITY Automated Urine Chemistry Analyzers and iRICELL Systems Purpose: Provide Global SERVICE Organization and distributor partners with information about how to resolve SPM related issues with lower cost repair parts instead of replacing the entire module. Discussion: The SPM is a high cost module in the iChemVELOCITY Analyzer. In order to reduce costs associated with servicing this analyzer, information pertaining to resolving SPM related problems with lower cost repair parts instead of replacing the entire module is provided in this TECHNICAL bulletin .

2 IMPORTANT NOTES: 1. Certain repair parts are backwards compatible to specific revision levels of the SPM. For these repair parts, the information will be documented below the section and replacement part number in this bulletin . 2. There will be situations when the entire Strip Provider Module will require replacement; however, this TECHNICAL bulletin provides multiple examples of how the SPM can be repaired at a lower level instead of replacing the entire module. 2 1. Strip Load Cylinder, Spare (P/N 700-7250S) Movement or rotation problems related to the Strip Load Cylinder are issues that can many times be resolved by the customer. Replacing the Strip Load Cylinder normally does not require an on-site SERVICE visit.

3 This part can be shipped directly to the customer for replacement. 2. PCBA, SPM Strip Loading Cylinder Sensor (P/N 101-7025) This sensor on the back of the SPM for the Strip Load Cylinder can be replaced by unplugging the connector from the sensor, removing the screws/ fasteners holding the sensor in place, removing the old sensor, installing the new sensor and plugging in the connector. The symptoms of this sensor going bad will be the instrument will remain in constant measure mode and will not process samples. 3. SPM Magnet Assembly Retrofit Kit (P/N 799-7033) This kit is used if the magnet on the back of the Strip Loader Module needs to be replaced. The magnet is secured to the Strip Load Cylinder by one screw. If this magnet falls off the back of the strip loader module, the SPM strip loading cylinder sensor will not be able to determine when the Strip Loader Cylinder is in the correct locked position.

4 This will result in the instrument remaining in constant measure mode and the instrument will not process samples. 4. SPM Home Sensor Replacement Kit P/N (799-7029) This kit contains one pre-assembled cable, connector and home sensor that will work for the wiper, extractor, feeder, or flipper. The SPM home sensor replacement procedure can be done with the SPM installed or with the SPM removed from the instrument. The instructions below document how to replace an SPM home sensor with the SPM removed from the instrument. Step a: Turn off all electrical power to the Instrument. Remove the SPM from the Instrument. Step b: Remove the Sensor: Remove the malfunctioning sensor and cable. Discard the screws and washers. Notice how the cable was routed and tied so the pattern can be repeated when installing the replacement cable and sensor.

5 3 Step c: To Install the Wiper, Flipper or Extractor Sensor: Use the short Screws provided. Washers are not to be used. Route the cable along the same path as the cable just removed. To install the feeder home sensor, Use the white Spacers and the long Screws provided. Washers are not to be used. Route the cable along the same path as the cable just removed. 4 Step d: Secure the cable. Use cable ties provided in the kit to secure the new cable. Step e: Use markers provided to properly identify the new cable. Step f: Before re-installing the SPM, check that the Strip Provider Housing opens and closes freely without pulling on the Cables. Step g: Re-install the SPM, verify the SPM calibrations in accordance with the SERVICE Manual, and conduct the Performance Verification.

6 5 5. SPM Strip Loading Housing Cover (P/N B39121) This top cover was modified and implemented in instrument serial number V02140. Instruments that experience issues with strips jams when loading strips should be checked to determine if this top cover is installed on the SPM. The Strip Loading Housing Cover (P/N B39121) is backwards compatible from the current SPM P/N B39124 to SPM 700-7200 Revision AD. 6. SPM Cover Crossbar Kit (P/N 800-7023) This part is replaced if the SPM has problems associated with opening and closing the SPM cover. Instrument S/N VO1224 is the first instrument that was manufactured with the SPM Cover Crossbar Kit. All Strip Provider Modules P/N 700-7200 Revision AD and later and Strip Provider Modules P/N B39124 are manufactured with the SPM Cover-Crossbar Kit.

7 This kit contains the following parts: Replacing the captive SPM cover screws, springs, washers, crossbar and crossbar retaining screws enable the SPM cover to securely closed and this make it easier for the operator to open and close the SPM. The SPM cover-crossbar kit can be used with SPMs P/N 700-7200 Revision V and later and all SPMs P/N B39124. Captive SPM cover screws 2 EA P/N 690-7117 Springs 2 EA P/N 692-7156 Retainer washers 3 EA P/N 690-7119 Crossbar 1 EA P/N 661-7286 Crossbar retaining screws 2 EA P/N 690-3012 Instructions 1 EA P/N 300-5432 6 7. Extractor presence sensor (P/N 101-7008) Extractor presence sensor flat cable (P/N 101-7028) Extractor magnet assembly, spare (P/N 700-7280S) If the SPM wiper is singulating the strip to the extractor but the extractor is ejecting the strip back into the SPM strip housing chamber, the following must be checked: a) Verify the extractor presence sensor flat cable is plugged in at both ends.

8 B) SPM extractor and wiper calibration should be verified. c) If line items 7a and 7b have been verified as correct, verify operation of the extractor presence sensor in chemistry SERVICE mode. Make sure the SPM strip at extractor consistently changes state between 1 and 0 when a chemistry strip is inserted and removed from the extractor. d) Problems associated with the chemistry strip being ejected back into the SPM strip housing chamber are normally resolved by replacing the extractor presence sensor, extractor presence sensor flat cable, and extractor magnet assembly. 7 8. For issues related to the iChemVELOCITY chemistry strip being placed upside down on the Strip Conveyor System, the following items must be checked: a) Make sure the chemistry strips properly loaded into the SPM.

9 If the chemistry strips are loaded with the black marker facing the front of the SPM, the chemistry strips will be placed upside down on the Strip Conveyor System (SCS). This will result in a Chem N/A and Strip Deviate result. b) If the chemistry strips are properly loaded into the SPM but the strips are still being placed upside down onto the SCS, check to ensure the SPM feeder and flipper connectors are properly plugged into the SPM interconnect board (See diagram below - J20 and J21). If the connectors are plugged in properly, verify the SPM feeder and flipper calibration. If the SPM feeder is not stopping at the correct location when the SPM strip presence and orientation sensor is determining the orientation of the chemistry strip, the flipper will fail to rotate the chemistry strip to have the pads facing the upward position.

10 If the feeder calibration is correct, check for proper operation of the SPM flipper. 8 c) If line items 8a and 8b are correct, verify proper operation of the SPM presence and orientation sensor in chemistry SERVICE mode. Make sure the SPM strip presence or orientation sensor changes state between 1 and 0 when a strip is placed in front of and removed away from the sensor. If the sensor is not working correctly, replace the sensor (P/N 101-7009). 9. For strip jams at the extractor gate, check the following: a) Determine if there is any debris in the SPM chamber. Make sure to check the inner and outer grooves of the SPM chamber. b) Determine if there is any debris inside the extractor.
