Recovering from an emergency stop
After you press the button on the emergency-stop pendant, the robot stops. One of the
following occurs:
•
If you stopped a protocol run, a dialog box opens in the VWorks software.
•
If you stopped the robot while diagnosing problems in BenchCel Diagnostics, a
motor-disable message appears on the screen.
Use the following procedure to recover in either case.
To recover the BenchCel device after an emergency stop:
1
If the robot dropped labware before or during the emergency stop, remove labware
that was dropped. Also remove labware at teachpoints or other locations.
2
If the BenchCel robot attempted to place labware at a location that was not free, a
collision might have occurred resulting in misalignment of the robot gripper. Check
the robot gripper alignment:
a
Move the robot arms so that they are perpendicular to the
x
-axis.
b
Make sure the bottom of the robot gripper pads are perpendicular to the robot
arms. If they are not, contact Agilent Technical Support.
