Modifying Gradient, Event, And Detector Tables - Waters 600e User Manual

Flow causes switch S4 to default to the Off position. This action provides an additional
level of control for non-IEEE devices.
Note: The receipt of the Stop Flow signal (at the 600 controller's Stop Flow rear panel
terminal) suspends the controller's run, gradient, and event clocks. The three clocks
resume operation when the Stop Flow signal terminates.
To stop flow:
1. Press the Stop Flow screen key. This key acts as a toggle and changes to Resume
when you press it.
2. When you press Stop Flow:
• Flow rate is set to zero
• Gradient clock stops
• Run-time clock continues
3. To continue running the method, press the Resume screen key. This key changes
back to Stop Flow again.
4. When you press Resume, the pump ramps up to the flow rate at which it was
running when you pressed Stop Flow, and the method continues.
