Device Control
You have access to precise Echo device control. The ability to command internal mechanism movement is useful during
maintenance, troubleshooting, and diagnostic procedures. Access to device control is found in several areas of the Echo Liquid
Handler software:
l The Device Control and Status section of the Diagnostics window uses eleven sets of checkboxes and status indicators
that allow you to control the Echo Liquid Handler. They are discussed below.
l The Miscellaneous section of the Diagnostics window uses the diagnostic procedures drop-down list and Launch button.
For more information, see Diagnostic Procedures.
l The Motion section of the Calibration window uses the Home and Register buttons.
Note: The Echo Liquid Handler will not allow device movement that would cause damage to itself. For example, if the
door is closed when the source plate gripper stage is commanded to extend outside, the Echo Liquid Handler opens the
door first.

Door Open/Close
The Echo door can be manually opened and closed by selecting the appropriate checkbox.
If either the source or destination plate gripper stage is extended outside of the Echo Liquid Handler when the door is
commanded to close, a Close Door Error dialog box is displayed.

The associated indicator lights report the current position of the door.
