Position beaker / Swing robotic

arm

parameter: tower

(Tower 2 not possible)

parameter: position

With the MOVE command rack positions are moved to, i.e. the turnta-

ble rotates until the sample rack is positioned so that the selected rack

position is placed in front of Tower 1 or 2 (if present). If no 786 Swing

Head is mounted then only the rack positions of a 1-row rack can be

accessed.
With 786 Swing Head
If a 786 Swing Head is mounted then any rack positions can be moved

to. The angle of rotation of the rack is then compared with the swing

angle of the robotic arm and corrected accordingly.
In addition to a rack position, the robotic arm of a 786 Swing Head can

also be swung to any external position. The selectable external posi-

tions ext.1 to ext.4 can be defined in the whole swing range from 0° up

to the maximum swing angle of the robotic arm. For example, this

means that it is possible to move to a titration cell located beside the

sample rack.

Beispiele:

MOVE 1 sample

MOVE 1 ext.1

MOVE 1 spec.1

MOVE 1 5

MOVE 1 next

MOVE 1 +2

Moves sample beaker (defined by SAMPLE variable) in front of the tower

Moves robotic arm to external position 1

Moves special beaker 1 in front of the tower

Moves rack position 5 in front of the tower (absolute positioning)

Moves next highest rack position in front of the tower

Depending on the current sample position (SAMPLE variable), moves the next position

but one in front of the tower (relative positioning)

Parameters

sample – rack position corresponding to the current value of the SAM-

PLE variable, see also p. Fehler! Textmarke nicht definiert..
ext.1 to 4 – predefined angle positions of the robotic arm. These are

defined in the configuration of a tower, see also p. 17.
next, prev. – from the current rack position the next highest (next) or

the next lowest (prev.) will be moved to. Special beaker positions will be

skipped. If MOVE next is used at the highest rack position then the

move will be made to position 1. If MOVE prev. is used at rack position

1 then the highest possible position will be moved to.
spec.1 bis 16 – reserved special beaker positions on the sample rack.

These are defined in the rack configuration, see also p. 20.
