BenchCel Microplate Handler 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. An
8-mm offset works 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
for detailed
instructions.
The sensor intensity and threshold
require adjustment.
See
“Setting sensor thresholds” on page 99
for detailed instructions.
No plate in stack
The plate-presence sensor does
not detect a microplate in the stack
because of one or more of the
following:
•
No microplate is in the stack.
•
Plate presence threshold is not
set correctly.
•
The plate-presence sensor is
not working properly.
Verify microplates are loaded in the correct
stack.
If the problem persists, contact Agilent
Technical Support.
Operation timed out
The robot was unable to execute a
command.
In the error message dialog box, click
Retry
. If
clicking Retry does not resolve the problem,
restart the BenchCel Microplate Handler.
If the problem persists, contact Agilent
Technical Support.
Plate in grippers
The robot senses a microplate in
its grippers, but it does not expect
to have the microplate for the
specified command or action.
In BenchCel Diagnostics, use commands to
move and place the microplate at an available
teachpoint. Retry the intended command.
