Animal Blood Chemistry Analyzer
BS-200 Chemistry Analyzer Preventive Maintenance ManualGlobal Technical Support Department For Bio-ChemistryDear Service Engineer, It is well known fact that instrumentation which is well taken care of will out perform and out last than which is not. The Mindray BS-200 Automatic Chemistry Analyzer is no exception to this rule. Chemistry systems that are well taken care of by their users and service personnel will have many fewer problems than those which are not. Fewer problems mean fewer service calls, and happier customers. The preventive maintenance (PM) manual is offered as a standard guide to follow. You will find that, depending on the quality of care which an instrument receives, 12 months preventive maintenance visits will require varying degrees of thoroughness. The important point here is that the reliability of the Mindray BS-200 is somewhat dependant on the quality and quantity of attention it receives during its 12 months preventive maintenance visit. The service engineer has a substantial amount of influence on the call rate of each system. Taking a little extra time to educate users as to the proper way of caring for an instrument will, on most cases, increase the instruments reliability, and the customer’s satisfaction. This manual is intended for use only by Service Engineers who are trained by Mindray and do not replace or reduce the operator maintenance recommended in the BS-200 Operator’s Manual. Unauthorized use of these procedures can damage the analyzer and void the warranty of contract. The PM kit contains the parts needed for the preventive maintenance. Other parts can be replaced at additional cost. If you have any questions or suggestions, please email us at [email protected] Sincerely, Mindray Service TeamCatalog 1Part list of Preventive Maintenance Kit .................................................................... 3Replacement ................................................................................................................ 52.1Replacing Halogen Lamp(50W) ........................................................................ 52.2Replacing Sample Probe And Washer&Uncloging Probe............................. 72.3Replacing Syringe Plunger ............................................................................... 112.4Replacing Mixing Bar and Retaining Nut ....................................................... 132.5Replacing Filter Assembly ................................................................................ 142.6Replacing Check Valve ..................................................................................... 16Chemistry Maintenance schedule………………………………………….181 Part list of Preventive Maintenance Kit FRU801-BA20-00186-00DefinitionBS-200 Preventive Maintenance KitPart NoNameBA30-10-06365Halogen Lamp(50W)BA40-30-61525Sample probe0040-10-32307Washer for Probe115-003182-00Probe Unclog Tool0000-10-10916Acupuncture Needle10082-000731-00Syringe Plunger (500ul, zero dead volume)0040-10-32303Washer for SyringeBA31-20-41651 +Mixing Bar + RetainingBA30-20-06774 BA31-30-56750 M6Y-020003---Nut Filter Assembly (2 Pcs, 1pkg) Check ValveTime: The average time to complete this preventive maintenance procedure is 4 hours, it depends on the on-site engineer experience and analyzer condition.Qty1 2 1 1 42 Replacement 2.1 Replacing Halogen Lamp(50W) 2.1.1 Part Number BA30-10-06365Halogen Lamp(50W)2.1.2 Purpose For sufficient lamp intensity and reliable testing results 2.1.3 Interval Every 6 months Every 1000 hours When the machine reminds you to do so 2.1.4 Procedures 2.1.4.1 Place the Main Power to OFF.

Gently push the probe 2.2.4.13 upward and then release the probe to see if the spring can move freely. If yes, proceed to the next step. If not, check for errors and try again after removing the errors. 2.2.4.14 Connect the probe’ s circuit connector back to the circuit board2.2.4.15 Ensure the gasket is inside the probe2.2.4.16 Exercise caution when connecting the probe. Excessive force may bend the probe. Screw (clockwise) the probe’ s fluid connector back to the tubing connector.2.2.4.17 Add deionized water to a clean cup. Immerse the probe tip into the water by about 3mm and the LED on the circuit board will be lighted. Take the probe tip out of water, and the LED will be off. If the test succeeds, proceed to the next step.2.2.4.18 Check the marks inside the probe arm cover to see the orientation of the cover. Install the cover back to the probe arm.The marks inside the probe arm cover are shown in the figure below.102.2.4.19 Pull the probe arm to its highest point and rotate it to move the probe to a position above the wash well. 2.2.4.20 Load the sample/reagent disk.2.2.5 Verification Run the machine if no leakage around the connector，the replacement is OK.2.3 Replacing Syringe Plunger 2.3.1 Part Number 082-000731-00Syringe Plunger (500ul, zero dead volume)0040-10-32303Washer for Syringe2.3.2 Purpose For reliable aspiration 2.3.3 Interval Every year Every 100000 movements 2.3.4 Procedures 2.3.4.1 Place the Power to OFF2.3.4.2 Unscrew the screws on the syringe cover and remove the cover.
