Error message
Deadlock detected

found
Flash operation not
successful
The gripper positions
are too close
140
Cause
The microplate is assigned to the
wrong labware class.
The protocol run is unable to
continue. Some or all of the target
locations are unavailable, so the
microplates cannot be moved to
those locations.
The BenchCel device is not
connected to the controlling
computer, or the incorrect profile is
used.
The robot could not write to its
flash memory.
The Gripper open position
parameter value is less than the
Gripper holding plate position
parameter value.
Solution
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
Control Setup Guide.
Review the protocol and the run log. Run the
simulator to determine the reason for the
deadlock. In addition, check that the number
of simultaneous microplates is not too high.
See the VWorks Automation Control User
Guide.
To connect the device:
1
Turn off the BenchCel Microplate Handler
and exit the VWorks software.
2
Ensure the BenchCel Microplate Handler
is connected to the controlling computer.
See "Connecting the computer" on
page 57.
3
Wait 10 seconds, and then turn on the
BenchCel Microplate Handler.
4
Wait for the BenchCel Microplate Handler
to finish its homing routine, and then start
the VWorks software.
To check the profile:
1
In BenchCel Diagnostics, click the Profiles
tab.
2
Check or select the correct profile. Verify
that the profile uses the correct the COM
port number (serial) or Ethernet ID.
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.
In the labware definition, make sure the
Gripper open position value is 3 mm or greater
than the Gripper holding plate position value.
You can change the parameters in the
Labware Editor or in BenchCel Diagnostics.
