Figure 3.9 Inverting the destination plate
As the destination plate gripper stage retracts into the Echo liquid handler,
a sensor detects whether a plate is or is not present. Normally, a transfer
will not be executed if a destination plate is not detected. The human
operator, or a controlling program, can override the plate presence check,
if necessary.
When the destination plate gripper stage extends out of the Echo liquid
handler, the plate is rotated back to its upright position.
3.2.5 Status indicator lights
There are three status indicator lights on the front of the Echo liquid
handler and a duplicate set on the rear panel.
A quick glance can confirm whether the Echo liquid handler is operating
normally or that it needs operator attention. The
Power light (green) is on
when the instrument on and initialized; the Warning light (yellow) turns
on when a condition is outside of normal limits, but the instrument can
continue to operate; the
Fault light (red) turns on when a condition
exceeds warning conditions and the instrument can no longer operate.

Power light
 Green: Normally the Power/Ready light is turned on, indicating that
the Echo liquid handler is both turned on and that its internal
controller has completed its initialization and is ready.
 Off: When the Power/Ready light is turned off, either the Echo liquid
handler has not been turned on or its internal controller has not
completed initialization.
