1. Preventive Maintenance Schedule
The preventive maintenance program requires the application of the following maintenance procedure
(see chapter 2) with the following interval:
Each 25000 tests executed or (if the number of tests is less) each 4 months
2. Periodical Maintenance Procedure
To start the procedure power on the instrument and enter in the Service Menu as described in the
Service Manual.
2.1. Internal Bus Connection Checks
To test the quality of the internal bus connection verify the +5V power supply voltage on the two
boards that are located at the end points of the two longest bus sections, that are the Analysis
Module Bus Section (7 boards cascaded) and the Loader Module Bus Section (up to 8 boards
cascaded).
The last board of the Analysis Module is the Positioner (addr. 0x01) Motor Driver board; the last
board of the Loader Module is the Horizontal Clamp (addr. 0x10) Motor Driver Board.
On these boards measure the +5V power supply voltage between pin 1 and pin 4 of JP2 vertical
strip connector of the Motor Driver Board (see Figure below).
The minimum voltage admitted voltage in quiet conditions is 4.9V.
If the measured voltage is below this value execute the following checks:
-Check all the connections of the internal bus, starting from the Power Supply Unit to the
motor Driver Board under test (see chapter 6 – Electronics interconnections layout of the
Service Manual).
-Increase the 5V power supply voltage from the Power Supply board that is inside the
Power Supply Unit. Following the instructions of paragraph 4.3.1 – Power Supply Unit of
the Service Manual set the 5V output to a voltage between 5.3V and 5.4V.
GND
+5V

2.2. Sample-Holder Chain Checks
2.2.1. Sample-Holder Chain Positioning check
a) Manually insert 3 tubes in the Sample Holder Chain: the first in the position immediately
before the Reader 1; the second in the position immediately before the Reader 2 and the
third in the position immediately before the Ejector.
b) From the Service Menu execute the Single Step function of the Sample Holder Chain.
c) Activate the reading function of the Reader 1 and check that the tube is centered respect
to the Reader Unit during the whole movement of the reading Sensor. Also Check that
the White Led has been activated for the whole movement of the sensor.
d) Activate the reading function of the Reader 2 and check that the tube is centered respect
to the Reader Unit during the whole movement of the reading Sensor. Also Check that
the White Led has been activated for the whole movement of the sensor.
e) Manually move the Sorter Unit to the most external position, in order to have access to
the tube that is located over the Ejector.
f) Activate the expulsion function of the Ejector, and manually take the tube when it
reaches the End-Run position. Now check that the Ejector is centered respect to the
Chain loop.
Notations:
If observe the same misplacement on all the three units (Reader1, Reader2 and Ejector), adjust
the End Offset of the Positioner Module.
If the misplacement regards only one or two unit, perform a mechanical adjustment on the
misaligned units.
2.2.2. Sample-Holder Chain Tensioning check
Repeat the procedure of paragraph 2.1.1 for 3 times total, with 30 chain single-step after each
procedure execution, and make the following check:
If there are positioning differences between the three executions check the tensioning of the
sample-holder Chain and that of the transmission belt located inside the Analysis Module Base.
If you alter one of the two tensioning you have to recalibrate the End offset of the Positioner
Module.
2.2.3. Sample-Holder Chain Integrity check
Make a visual check of all the 89 elements of the Sample Holder Chain and replace those that
exhibit some damage especially to one of the two lower arms.

2.3. Functional Check of Electromagnets
Check the Sorter and the Insertion electromagnets, following the Service manual instructions.
Repeat the activation/deactivation sequences 10 times with 5 seconds interval between them.
2.4. Functional Check of Critical Sensors
Following the Service Manual instructions check the following sensors:
-Clamp Barrier Photo Sensor: Module Horizontal Clamp, address 0x10.
-Sorter Tube Reflective Sensor: Module Sorter, address 0x07.
-Insertion Tube Barrier Sensors (Upper and Lower): Module Insertion, address 0x16.
-Tube Sensor under chain: Module Positioner, address 0x01.
-Tube Sensor under Ejector: Module Mixer address 0x04.
2.5. Cleaning
Remove dust and paper powder from the parts near the Insertion Point of the Sample Holder
Chain, and near the Ejector.
Using an air blow remove dust or paper powder from the tooth optical sensor (PH1) of the
Positioner Module.
2.6. Lubrication
Apply over the whole guide lenght the grease MOLYKOTE G-4500 supplied into a 5ml siringe
(CODE 30212260) of the following modules: Reader 1, Reader 2, Ejector, Ejector Clamp (for
Bayer configuration), Ejector Barcode (for Beckman-Coulter configuration). See figure below.

Lubricate, using Silicon Grease type CFG L00501 (Code 12400030), the coupling point
between the cam and the actuator of the Clamp (1), and the Clamp-Arms fulcrum points (2).
2.6.1. Rail Guides Lubrication
Recommended for:
-Transfer left motor
-Transfer right motor
-Horizontal Clamp motor
-Sorter Motor
1. Spray a small quantity of WD-40 lubricant (Code 12400040) in both the lubrication holes at
the faces of the carriage. Please pay attention to avoid to spray on “sensible” parts such as
sensors, solenoids, electronics boards, etc.
2. Manually move the carriage along the whole rail for at least 4-5 times.
3. Remove the lubricant in excess.

2.7. Readers Check
Using the Reading Sensor Test Tube (Code 19900900) insert them in one rack and start a fast
mode analysis cycle (Setting the Delay Time = 1). Follow the tube in the analysis module by
watching the proper window in the main menu. Immediately after the tube has passed the
Reader 2, press STOP, and from the DATA View menu look at the values read. They has to be
the same that is printed on the Label of the TEST TUBE. A tolerance of +/- 3 point is accepted.
2.8. Final Checks
Start an Analysis Cycle with at least 9 racks full with 10 tubes each. One of the Tube will be the
Check Device Test Tube (cod. 30003660).
Check the rack exchange in the Loader Module is correctly performed for all the 9 racks.
Check the integrity of the hooks of the 20 moving rack-holders in the Loader Module.
During the analysis cycle check the correct acquisition of the Check Device Test Tube.
Complete the Analysis cycle verifying that all the tubes are correctly managed and classified.
