Workstation Front Panel Controls
Description
Turns power on/off to the Workstation and to the components connected to it.
Stops the Workstation pumps and pauses a running method. When it is pressed, the
status LEDs for pumps A and B change from green to flashing red. To resume the
run,
• Press the button again, to restarts the pumps and the method, or
• Press the Continue button in the Run screen, or
• Press the START button in the Manual screen.
Before you press either purge button switch the AVR7-3 inject valve to the Purge
position in the Manual screen, so that the column is not exposed to high pressures
and flow rates.
The purge buttons flush the tubing lines with the solution connected to pumps A and
B. When the buttons are pressed, the green LEDs for pumps A and B flash. To stop
the flow, press the purge buttons again and the LEDs go off. These buttons do not
operate when the system is running a method.
When the purge buttons are pressed, the pumpheads run at their (default)
maximum flow (F10 purge rate is 10.0 ml/min or 20 ml/min when used with the
Maximizer; F40 purge rate is 40 ml/min or 80 ml/min when used with the
Maximizer.) To alter the default purge flow rate, select Manual Setup from the
Options drop-down menu.
This LED serves two functions:
a.
Constant red: Indicates that the pump has shut down due to a mechanical or
electrical problem. This includes a shutdown due to a high or low pressure
limit being exceeded. Pressure limits are set in the Manual and Run screens.
b. Flashing red: Occurs during a method run and indicates that a pre-programmed
ALARM step has been reached. The system operator must respond before the
method continues. Also, the Controller emits an audible tone.
c. Constant green: Indicates the pump is running.
