1 Operating the machine
1.1 General information
The loader is supplied after testing without being completely dismantled. It is only
detached from the analyser and the arm (3) with the fingers (6) (See figure arm
installation) are removed for safety reasons. Therefore, an adjustment after
installation may not be needed however the adjustments are described below.
They may be necessary for accurate readjustment.
1.1.1 Loader models
There are 3 standard loader models available:
130-crucibles version, 104-crucibles version and 36-crucibles version.
The difference between these models is the form of the loader’s platform, i.e. the
size of the loader. There is no difference with regard to loader arm, arm support
and drive, lasers/sensors, chain drive, pneumatics and electronics. Therefore the
adjustments, described in this manual are valid for all models.
1.1.2 Space requirements
Fig. 1: Loader positioning
Keep sufficient space to the right of the analyzer (minimum 86 cm) to place the
loader.
It is suggested to place the analyser in a position where the front end of the
furnace cover (1) aligns with the front end of the desk (2).
NOTICE
Under no conditions should the analyser and loader be placed in direct sunlight or
be exposed to the wind of air conditioners or to the wind blowing through open
windows and doors.

1.1.3 Connecting and disconnecting plastic tubes
To connect the tube, simply push it into the fitting as far as it would go.
Fig. 2: Plastic tube connecting
To disconnect the tube, first press the plastic ring of the fitting up to the metal ring,
keep it properly pressed and pull the tube.
Fig. 3: Plastic tube disconnecting
To reinstall the loader do this:
•The analyzer is switched off (Mains power switch on position 0).
There is no compressed air supply to the analyser.

1.2 Mechanical connection to the analyzer
Fig. 4: Autoloader reinstallation (Top view)
•Before starting reinstallation take a look at the plastic tubes and bear in mind
the way they are supported with the screw (7). Make sure to lay them the
same way during reinstallation.
•Place the loader to the right of the analyzer. The part (1) is the vertical bar
(profile) of the front right corner of the analyzer’s cabinet (top view of cross
section). For further orientation: The round part (2) is the left front foot of the
loader.
•The loader is positioned in a way that the vertical rod (3) is pushed towards
the cabinet so that the cabinet’s corner rod (1) is inside the vertical rod (3).
•The blade (4) is inserted between the rod (3) and the cabinet rod (1).
•The angle rod (5) is installed and fixed with the screws (6).
•Then the screws (7) are fixed so that a solid, stable mechanical connection
between analyzer and loader is made.

1.3 Chain motor belt adjustment
Fig. 5: Belt tension check
The toothed belt of the chain motor is located underneath the left-hand section of
the loader’s platform. The mechanical tension of the toothed belt (1) can be
checked by applying the force to the belt, as shown on the picture by the red arrow.
If an adjustment is necessary, loose the two screws (2) push the plate (3) to the
back in order to create an appropriate tension of the belt (1) and drive the screws.
After fixing the screws, check the tension of the belt (1) again.
In case of replacing the belt, the adjustment is made the same way.

Fig. 7: Chain tension adjustment (Bottom view)
The loader is supplied with the adjusted chain tension. If necessary, check the
tension of the chain as follows:
•Press and hold several crucible trays (1) of the rear row on the platform so
that they cannot move.
•Move a few trays (2) of the front row to the left and to the right.
They should move for about 1 mm. If not, loose the screw underneath the
toothed wheel (3) and adjust by moving it back and for.
•Fix the screw (3) and check again.
NOTICE
A too strong tension can lead to a blockage when the crucibles are moved by the
motor. If the chain plays too much, bent elements of the chain can block at the
indicated point (4). Therefore keep about 1 mm play as described above.
•Pull the front part (5) for about one or two millimetres.
The turning point is (6). When you release it, it should return back pressing
the crucible tray, which is at pick up position, to the wheel (7) behind the
tray. This is to make sure that each crucible when at pick up position is
always at the same place.

1.5 Finger adjustment
Fig. 9: Finger adjustment
The maximum distance inside the fingers (1) should be about 36 mm.
For adjusting:
•Loose the screw (2).
•Move the assembly (E) down to take it off the shaft (9) of the motor resp. off
the gear box (10).
•Unscrew the four screws (3).
•Remove the piston (4) with the plunger (5).
•Loose the nut (6).
•Screw the plunger (5) to the piston (4) clockwise for making the finger (1)
distance bigger.
•Fix the nut (6) again.
•Unscrew the plunger (5) from the piston (4) (counter clockwise) for reducing
the distance between the fingers (1).
•Fix the nut (6) again.
•Make sure that the plunger (5) is clean.
•Make sure that also the inside surface of the arm (8) is clean from dust,
grease etc.
