Comparing Controller Types 23
PowerLine Operation
The PowerLine controller provides product-specific setup and operating parameters for
PowerLine detectors and autoinjectors.
Detector parameters inlude:
• Detector filter constant
• Autozero (except for 431/432 detector)
•Polarity
• Absorbance Units Full Scale (AUFS)
• UV wavelength (λ)
• Sensitivity
•Lamp On/Off
• Filter
• Cell temperature
Injector parameters include:
• Syringe draw rate
• Inject delay
• Standards (how many and how often)
• Methods specifying vial numbers
• Number of injections from each vial
• Injection volume
Storage for Tables
The controller provides storage for 15 sets of tables. Each set of tables can include a:
• Gradient table - Contains a maximum of 15 operational steps that define the
varying eluent composition, flow rate, time range, and rate of change for each phase
of the gradient.
• Event table - Contains a maximum of 15 operational steps to control output signals
to external devices, internal alarms, sparge rate, column heater temperature, detector
lamp On/Off, and linking operation to other tables.
• Detector table - Contains a maximum of 15 operational steps to change wavelength
and attenuation during a run.
