Software problems
Error message Cause Solution
Deadlock The microplate is assigned to the
wrong labware class. Check that the labware belongs to the
correct labware class in the Labware
Editor. Most microplates should
belong to the Uses Standard Plate Pad
class. If you created a special class for
a particular microplate, make sure it
belongs to the special class.
For more information about setting up
labware classes, see the
BenchWorks
Automation Control User Guide .
No plate in grippers The Orientation threshold was used
to detect microplate presence, and
the sensor readings from all four
corners are below the threshold.
Note: The software always uses the
Orientation threshold as a
secondary check, even if the Check
Orientation option is not selected.
Reduce the Orientation threshold
value.
The Robot gripper offset parameter
value is incorrect. Correct the Robot gripper offset value
in the Labware Editor or in BenchCel
Diagnostics. Velocity11 recommends
an 8 mm offset for most labware.
No microplate is available at the
pickup location. Make sure you load or place labware
at the target location.
The Orientation sensor offset
parameter value is incorrect. Adjust the Orientation sensor offset
value in BenchCel Diagnostics. See
“Setting sensor thresholds” on page 1
for detailed instructions.
The sensor intensity and threshold
need adjusting. See “Setting sensor thresholds” on
page 1 for detailed instructions.
