Back View - Agilent Technologies Graphite Tube Atomizer GTA 120 User Manual

Getting Started
If the circuit breaker trips open during normal operation, this
indicates an over-current fault condition. Wait for at least 20 seconds
before attempting to close the circuit breaker again. If the circuit
breaker will not remain closed, call your Agilent field service
engineer.
Programmable Sample Dispenser Connections
The Programmable Sample Dispenser (PSD) is used with the GTA to
dispense solutions into the furnace. The inert gas supply connector
and control plug connector for the PSD are located in the power
supply compartment. See Figure 1 above.
The gas supply connector is a quick-connect automatic seal-off type
connector. This provides inert gas to pressurize the sampler rinse
system.
The control connector is a 25-way 'D' connector, which provides
drive and control signals for the PSD and power for the dispenser
actuator system.
For more details about the PSD and its installation refer to the PSD
User's Guide.

Back View

The back of the GTA control unit contains the appropriate inlets for
the power, water and gas supplies. A communications cable connects
the GTA to the computer IEEE card via the spectrometer.
The GTA will be set up, ready for use by a field service engineer
during installation. However, you can also refer to sections on the
Pages 26 and 27 for more information on the water and gas supplies.
