9.7 Adjustment of the up/down speed of the arm
The downwards speed of the fingers can be adjusted by the left hand adjustable restrictor (7),
see image pneumatic connections. The upwards speed of the fingers can be adjusted with the
restrictor (8). After adjusting, fix the knurled nuts.
1. Fingers close and take the crucible. If the adjustment of the fingers position is coaxial to
the pedestal resp. to the crucible, the crucible will not move in horizontal direction when
the fingers close.
The closing speed of the fingers can be adjusted with the adjustable restrictor (9) see
image pneumatic connections.
2. Fingers up.
3. Fingers turn to the disposal position.
4. The fingers open and the crucible is dropped.
5. The arm goes first to the home position and then it turns back to the pick-up position
6. Fingers down.
9.8 Repeating the single step cycle
It is advisable to make a couple of cycles with single step to make sure that the mechanical
adjustments, described before, are accurate. Continue pressing the adjustment button shortly to
advance to the next steps of the sequence. Check all adjustments.
When the adjustments are finished, fix the screws ensuring mechanical connection of the loader
to the analyser, see chapter 6 “Mechanical connection to the analyser”.
9.9 Non-stop cycle
In some cases the automatic repetition of complete cycles is required. For example, in case of a
continuous test of the loader by placing 130 empty crucibles for the loader to run 130 cycles in
unattended operation. Also at exhibitions the non stop mode without combustion is required.
This is obtained by keeping the switch pressed already before switching on the power, and by
keeping it pressed as long as the cycles have to run.
To do this:
1. Place the required number of crucibles on the loader.
2. In order to avoid the need of continuous manual pressing of the button, it can be
mechanically fixed in pressed position before switching on the analyser, by mechanically
connecting the button (4) with the connector (9) using a rubber ring.
3. The analyser is switched from position 0 to position 1 of the mains power switch.
4. After the last crucible is taken from the platform, the loader will turn the chain for a while,
looking for any more crucibles. If no crucible is found, the chain will stop turning. The
loader electronics will signalise the missing crucibles by triple beeping. See ERROR
