3.2.2 Tower settings
Sample Processor models with two towers can have each tower separately
equipped and separately configured. For models with a single tower only the
configuration menu for Tower 1 can be accessed.

max. stroke path 235 mm
Max. lift range for Lift 1
0…235 mm
This max. stroke path setting is important for safety reasons. Correct entry
of this value can prevent electrode breakage, as the titration head cannot
move any lower than the position entered here (0 mm = lower stop of lift).
>tower 1

Sets the minimum required beaker ra-
dius for processing at Tower 1
*, 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.

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 key and then move the lift or robotic arm
with the arrow keys < > and < > or < > and < >. The set values
can be accepted with and corrected later.
