142 Running PowerLine Methods
7.3.3 Running a Method
Note: The 600 controller examines the status of the 490E detector before initiating a run.
If the detector is in the standby state, the controller automatically turns on the lamp.
Using the Rheodyne 7725i Manual Injector
To begin a run with the Rheodyne 7725i manual injector:
1. Load the injector loop with sample. See Section 7.1.1, Using the Rheodyne 7725i
Manual Injector.
2. Turn the injector handle to the Inject position to make the injection. The injector
sends an Inject signal to the controller.
Using a PowerLine Autosampler
To begin a run with a PowerLine autosampler (717plus):
1. Load the sample vials into the autosampler.
2. Press the Start Run screen key. The 600 controller automatically starts the
autosampler. The system status changes from Initial to Inject Wait.
3. The autosampler draws the sample and makes the injection. The controller receives
the Inject signal through the IEEE-488 bus.
Using a Non-PowerLine Autoinjector
Note: If you are using an autoinjector, see the documentation provided with that product
for information on sample loading.
To begin a run with an external, non-PowerLine autoinjector:
1. Load the sample vials into the autoinjector.
2. Program and start the autoinjector. See the autoinjector operating instructions.
When the autoinjector makes the injection, it sends a contact closure signal to the
Inject input terminal on the rear panel of the controller.
Using the Start Run Screen Key with a Non-PowerLine Autoinjector
For methods development and for runs that are not time-sensitive, you may also use the
Start Run screen key to start a run with a non-PowerLine autoinjector.
To start a run with an autoinjector using the Start Run key:
1. Load the sample vials into the autoinjector.
