Data system startup sequence
This sequence requires you to start all devices in your data system
Tip:
operating before you start the computer. As you start each component, wait
briefly to allow its internal diagnostic tests to run. This ensures each module
functions and quickly identifies failures.
Perform the following startup sequence when you use the Prep system with
a data system:
1. Start all equipment not controlled by the data system.
2. Start equipment controlled by the data system that is not under direct
IEEE-488 control:
• Empower workstation – All equipment controlled through the I/O
distribution box (busSAT/IN modules and connected analog
detectors).
• Client/Server – All equipment controlled through the busLAC/E
module (SAT/IN modules and connected analog detectors).
3. Start the pump, establishing eluent flow. Then start all other devices
controlled through the IEEE-488 bus.
You cannot use the Run Samples window, nor run methods or
Tip:
method sets, until all devices on an Empower system's IEEE-488 bus are
calibrated and operating. However, you need not start instruments not
assigned to a system or assigned to one you do not intend to use.
4. Start the printer and monitor.
5. Start the computer.
PowerLine controller startup sequence
1. Start all equipment not controlled through the IEEE-488 interface.
2. Start all equipment controlled through the IEEE-488 bus.
3. Start the PrepLC controller.
Shutdown sequence for IEEE-488 devices
If you do not expect to use the Prep system overnight, or for longer periods,
shut down the system observing this sequence:
1. Ensure the system is purged of salts.
