Labcyte Echo 525 - Status Indicator Lights

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.
l The Power light (green) is on when the instrument on and initialized.
l The Warning light (yellow) turns on when a condition is outside of normal limits, but the instrument can continue to
operate.
l The Fault light (red) turns on when a condition exceeds warning conditions and the instrument can no longer operate.

Power Light
The states for the power light are listed below:
l Green: Normally the Power/Ready light is illuminated, indicating that the Echo Liquid Handler is both turned on and that its
internal controller has completed its initialization and is ready.
l 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.
Warning Light
The states for the warning light are listed below:
l Off: Normally the Warning light is turned off, indicating that the Echo Liquid Handler is functioning correctly.
l Yellow: The Warning light is illuminated when any of the following conditions are true:
l The Echo Liquid Handler stages are not homed or are in the process of being homed. For more information, see
Home Calibration.
l The coupling fluid bottle level is low. For more information, see Coupling Fluid Indicator.
Note: When the coupling fluid falls below its recommended minimum level, air bubbles may be introduced
into the coupling fluid, which reduces the accuracy or precision of source plate surveys and fluid transfers.
Labcyte recommends that you refill the coupling fluid bottle as soon as possible after the Warning light
has been turned on. For more information, see Echo Coupling Fluid Maintenance.
l The coupling fluid temperature is outside of the normal range and within the warning range. The normal range is
22.1°C ± 0.9°C. The warning range is 20.2°C – 21.2°C or 23.0°C – 24.0°C.
l The focus calibration check should be performed. For more information, see Focus Calibration Check.
l The door is neither fully open nor fully closed.
l The upper anti-static bar is neither fully up nor fully down.
l The source plate dryer nozzle is neither fully up nor fully down.
