AC power and fuse compartment: The AC power and fuse
compartment (also called the power input module) contains the main Echo
liquid handler power on/off switch, AC power outlet, and fuse
compartment. For more information, see “AC power and fuse
compartment” on page 3-14.
Coupling fluid bottle and caddy: The 1000 mL coupling fluid bottle
provides the coupling fluid (distilled water) that is pumped through the
acoustic transducer to maintain constant temperature and transfer acoustic
energy to the well. The coupling fluid bottle caddy contains a sensor that
monitors the fluid level and issues a warning when the fluid level is less
than 250 mL. For more information, see “
Coupling fluid bottle” on
page 3-15.
Status light indicators, LCD screen, and Emergency Off (EMO): Same
as the components on the front panel. Remote EMO cable enables the
customer to set up a remote EMO button more accessible to the operator.
Data connection: RJ-45 Ethernet network port connects the Echo liquid
handler to a PC or to a network. For more information, see “
Data
connection” on page 3-14.
Tubing and hose connections: the Echo liquid handler uses tubing and
hoses to connect to the chiller, house air, surge tank, and vacuum pump.
Waste water bottle (not shown, on older Echo systems only): The 500
mL waste water bottle collects overflow from the catch basin.
