Flow area
This area of the LCD display provides information about the pump flow rate.
• In Local mode, the display shows the flow rate that was entered for the
Flow parameter. The value is displayed in mL/min.
• In Remote mode, actual flow rate is not displayed. Instead, the display
reads Flow or
No Flow.
Pressure area
This area of the LCD display shows the pump pressure in the units selected in
the Unit parameter (psi, KPa, or bar). When running in Remote mode, the
pressure reading value that appears on the 515 LCD display may differ
slightly from the value that appears on the remote device.

Editing or entering parameters in local or remote modes

1. Press the Up, Down, or Menu key to display the appropriate parameter
in the menu items area.
2. Press the Edit/Enter key to position the blinking cursor within the
parameter.
3-12 Using the Waters 515 Pump
Meaning
Indicates the pump is in the Remote mode (Rem and Run
alternately appear in the Status area). If the flow area of the
display reads Flow, then the pump is running. If the display
reads No Flow, then the pump is waiting for the data system
or external controller to issue a run signal.
Indicates the pump is stopped in the Remote mode (Rem and
Stop alternately appear in the Status area). A Stop could
result from:
• Pressing the Run/Stop key.
• Fluid pressure exceeding the high-pressure limit for the
required time.
• Fluid pressure dropping below the low-pressure limit for
the required time.
