max. stroke path 125

mm

Max. lift range for Lift 1

0…125…235 mm

This max. stroke path setting is important for safety reasons. Correct entry

of this value can prevent, that i. e. an injection needle or tubing will be bent.

The working head cannot move any lower than the position entered here

(0 mm = upper stop of lift). Make these settings before you edit the rack

definitions.

>tower 1

min. beak. radius

* mm

Sets the minimum required beaker ra-

dius for processing a sample

*,

1…100 mm

* = any value

This is also a safety setting. In order to prevent a fully equipped, wide titration

head from trying to enter a narrow sample beaker a limit for the minimum

necessary beaker radius can be entered here. During a method sequence

the value entered here will be compared with the value given for the effective

beaker radius in the rack table before the lift is lowered and, if necessary, an

error message will be produced.

Entering * prevents a comparison from being made.

Submenu Swing Head

Open with <ENTER>

If a 786 Swing Head equipped with a robotic arm is mounted on the Sample

Processor then it is essential that the correct settings for the mounted robotic

arm are entered, as otherwise the instrument will not be able to position it

exactly.

Each of the following settings can be interactively defined with the LEARN

function. Press the <LEARN> key and then move the lift or robotic arm

with the arrow keys < > and < > or < > and < >. The set values

can be accepted with <ENTER> and corrected later.

For further explanations of the LEARN mode, see section 2.3.8.
