Recovering from an emergency stop

About this topic

This topic explains how to recover from an emergency stop after you pressed the red button on the emergency stop pendant.

After you pressed the emergency stop button

After pressing the emergency stop button, you must restore the system for normal operation.

IMPORTANT You cannot resume or recover a protocol run after pressing the emergency stop button. You will need to rerun the protocol after restoring the system for normal operation.

Before you restore the system, make sure you remove labware that might have been dropped during the emergency stop. Also remove labware at teachpoints or other locations.

To restore the Direct Drive Robot after an emergency stop:

1	Restore power to the robot. To do this, turn the red button on the emergency stop pendant clockwise. The spring-loaded button pops up.

 

2	If you stopped a protocol run in an emergency, select one of the following in each of the device dialog boxes to restore the device for normal operation:

 

Selection	Description
Diagnostics	Opens the device diagnostics dialog box. Note: This selection is available only when you are in the middle of a protocol run and not while you are already in the device diagnostics software.
Retry	Attempts to restart the current command or task in the run.
Ignore and continue	Ignores the current command or task and continues to the next command or task in the protocol sequence.
Abort	Aborts the current command or task in the run. Select Abort if you have determined that the protocol run is not recoverable.

3	If there is labware in the Direct Drive Robot robot gripper, release it and move it back to the pickup location. To do this:

a	Determine the location from which the labware was picked up.

b	In the Robot Error dialog box, click Diagnostics.

c	Hold the labware in your hand so that the labware does not drop when you release it from the robot grippers.

d	Click Open in the DDR Diagnostics Jog/Teach tab to release the labware to your hand.

e	Place the labware at the pickup location.

4	Click Abort Process in the Stop dialog box.

5	Exit and restart the VWorks software. Communication with the robot is re-established.
