Coupling Fluid Temperature and Indicator
The coupling fluid temperature inside the Echo Liquid Handler is reported in degrees Celsius. The operating range for the
coupling fluid temperature is 22.1°C ± 0.9°C. The coupling fluid controls the temperature of the acoustic transducer. A correct and
stable acoustic transducer temperature is required to maintain accurate and precise liquid transfers.
The coupling fluid temperature indicator reports three states:
Green. Coupling fluid temperature is OK.
Yellow. Coupling fluid temperature warning: The coupling fluid temperature is outside of the normal range: 21.2°C–23.0°C.
Red. Coupling fluid temperature fault: The coupling fluid temperature is outside of the warning range: 20.2°C – 24.0°C.
RF Temp 1 Temperature
The temperature inside the Echo controller is reported in degrees Celsius. Normal RF Temp 1 temperature is between 35–55°C.
As the reported temperature exceeds 55°C, performance could occur.
Maintenance Mode
Maintenance mode disables Echo motor control from the client software to allow you to perform maintenance procedures, such as
changing fluid.
Select the Maintenance Mode checkbox to inhibit the execution of the following Echo processes and functions from the Echo
Liquid Handler software:
l Executing fluid transfer protocols
l Door open/close
l Source microplate extend/retract
l Destination microplate extend/retract/flip
l Source microplate dryer up/down/on/off
l Anti-static bars up/down/on/off
l Coupling nozzle up/down
l Executing the dry plate diagnostic procedure
l Executing the move to well diagnostic procedure
l Executing the perform survey diagnostic procedure
l Homing the stages
l RF Power calibration
l Acoustic transducer calibration
l Barcode scanner calibration
The following Echo functions continue to be available during maintenance mode:
l Creating, editing, or deleting fluid transfer protocol definitions
l Creating, editing, or deleting destination plate definitions
l Turning the coupling pump on or off, or changing its pumping direction to normal or reverse
l Executing either a hard or soft reset of the Echo controller
Always clear the Maintenance Mode checkbox when returning the Echo Liquid Handler to normal operation.
