GENERAL DESCRIPTION

1? Using the Manual

1-1-1 This service manual provides service information for the CLINITEK?ATLAS?Rack Sample Handler,

model 5023 and the CLINITEK?ATLAS?Rack Sample Handler Bar Code Reader, model 5258.

1-1-2 Throughout this book, this symbol may be found:

 Use this 揵ook?to locate more information on the same subject.

 To locate specific servicing information, refer to the Table of Contents on page iii.

1-1-3 The CLINITEK ATLAS Rack Sample Handler (also known as the Rack Sample Handler) is mounted

to, and used with, a CLINITEK?ATLAS?Automated Urine Chemistry Analyzer, models 5001C, 5001L

or 5011. Using retrofits, It may also be added to models 5001B and 5001X.

 See Service Bulletins ATLAS-101 and ATLAS-102 for more information regarding retrofitting

model 5001B and 5001X units to accommodate the Clinitek Atlas Rack Sample Handler.

 To service the Clinitek Atlas Analyzer, refer to the Clinitek Atlas Service Manual, part number

99A50018.

 For information on Clinitek Atlas operation, refer to the Clinitek Atlas Operating Manual with

Rack Sample Handler, part number 99950239.

1-1-4 This manual is current as of the copyright date (June 1998). Any future revisions or additional

servicing information will be covered by Service Bulletins.

1-1

1? Instrument Description

1-2-1 Together, the Rack Sample Handler and Clinitek Atlas Analyzer become an automated system for

the analysis of CLINITEK?ATLAS?Reagent Pak, product code 5017. Each pak contains 490 +10/-0

reagent strips. Each strip contains ten pads used to provide nine different reagents and one

characteristic (colour). Two additional tests (Specific Gravity and Clarity) are done by this sys-tem.

1-2-2 The Rack Sample Handler plugs into the Clinitek Atlas analyzer through connector J1401 on the

Clinitek Atlas unit. In doing this, it replaces the CLINITEK?ATLAS?Sample Handler, part number

5003A.

1-2-3 The CLINITEK?ATLAS?Rack Sample Handler Fixed Bar Code Reader, model 5258 is an optional

addition to the Rack Sample Handler. This bar code reader reads sample tube bar code labels for

positive sample identification, collated with the urine results obtained on the Clinitek Atlas analyzer.

1-2-4 Urine specimen tubes are loaded into Clinitek?Atlas?Specimen Tube Racks, product code 5262 (ten

to a pack-age). Each rack holds ten tubes. Racks are placed into the Rack Sample Handler load

area. Each rack is transported in, across, and out of the Rack Sample Handler to analyze the urine

specimens. Test results are displayed and may be sent to an external printer and computer. The

rack is then moved into the unloading area, where it can be removed and new specimens added. Up

to 20 racks of ten tubes each can be loaded at one time (200 tubes); a full run of 200 tubes can be

tested in about one hour.

1-2-5 A Clinitek?Atlas?Stat Rack, product code 5263, may also be used to run STAT samples.

1-2-6 A Stop Marker (part number 50361095) may be inserted into a rack to stop operation once the

marker is identified by the system.

INSTALLATION

3-1 Introduction

3-1-1 This chapter explains how to locate information regarding installation of the CLINITEK?ATLAS?Rack

Sample Handler.

3-2 Installation



Refer to the Clinitek Atlas Automated Urine Chemistry Analyzer with Rack Sample Handler

Operating Manual, part number 99950239, Section 2, for instructions on installing this system.

3-2-1 In addition to the instructions in the operating manual, the following should be checked during the

installation:

1.

the waste tubing from the Clinitek Atlas system Rinse Well to the waste bottle must be fixed to

the rear wall without any sag. If there is a sag or stagnation of waste water in the waste tubing,

waste water may over-flow from the Rinse Well and electrical problems may then occur with the

Rack Sample Handler unit.

2.

The waste tubing must have a little slope towards the left side wall of the Atlas unit. The tube

end of the waste tubing must be cut so as to not touch the surface of the waste container, even

if this waste container becomes full.

3.

the system must be placed on a flat, stable and level surface for optimum performance.

NOTE:

If problems are seen during an initial installation, the Mother PC Board connectors

may have come loose. See paragraph 9-6 on page 9.13 to access these connectors.

Then reseat all the connectors, using the paper guide printed on top of the card cage

and Figure 6-7 on page 6.9

CHAPTER SIX

FUNCTIONAL BLOCK DIAGRAMS AND THEORY

Figure 6-1 Rack Feed Assembly (In Feed and Out Feed Assembly)

6-1

6-1 Introduction

6-1-1 This chapter describes basic theory of operation for the CLINITEK?ATLAS?Rack Sample Handler.

6-2 Set-Up and Use

6-2-1 Prior to instrument operation, the Rack Sample Handler must be connected to the Clinitek?Atlas?

Analyzer.

6-2-2 The Rack Sample Handler and Clinitek Atlas unit must be installed on a level, flat, stable surface.

 See the Clinitek Atlas Automated Urine Chemistry Analyzer with Rack Sample Handler

Operating Manual (part number 99950239), Section 4, for setup instructions.

6-3 Instrument Modules

6-3-1 The Rack Sample Handler consists of the following major modules:

1.

Rack Feed Assembly (paragraph 6-3-2)

2.

Cross Feed Assembly (paragraph 6-3-3)

3

Return Feed Assembly (paragraph 6-3-4)

4.

Power Module, Atlas Joint PC Board and Power Supply (paragraph 6-3-5)

5.

Display Assembly (paragraph 6-3-6)

6.

Card Cage Assembly (paragraph 6-3-7)

7.

Driver Assembly (paragraph 6-3-8)

8.

Stat Tube Holder (paragraph 6-3-9)

9.

Barcode Reader (paragraph 6-3-10)

10.

The Instrument Sensors (paragraph 6-3-11)

6-3-2 The Rack Feed Assembly

6-3-2-1

Each Rack Sample Handler instrument contains two nearly identical Rack Feed Assemblies (see

Figure 6-1):

1.

an Infeed Assembly to move a tube rack towards the pipette for sample testing

2.

an Outfeed Assembly to move the tube rack away after specimen sampling is completed.

The sole difference between the two units are the ID tags for motors and sensors, which are

different on each unit.

6-3-2-2

Using steel cables (items 36 and 37 on Figure 6-1) and plastic pulleys (16 and 50), the In Feed /

Out Feed Units move the trays with two levers (5 and 44) that contact the racks. These levers are

pressed down by the tube racks when their motions are reversed.

6-3-2-3

On the In Feed Assembly, a 24 VDC PF55-48K1 1/5 PM1 Stepper Motor (item 29), rotates a

Winding Drum (31) which moves the steel cables. This motor is homed using ORG1 (搊rigin sensor

1?, a 5VDC EE-SX153 photodiode / phototransistor sensor (item 26).

6-3-2-4

The same 24 VDC Stepper Motor is used by the Out Feed Assembly: it is called the PM3 Out Feed

Motor (item 29). On the Out Feed Assembly, this motor is homed using ORG3, a photodiode /

photo-transistor sensor (26)
