Press Limits
Defines the high and low operating-pressure limits of the Waters 600E pumps.
Your system, column, and packing chemistry determine the low- and high-pressure limits.
See the Care and Use Manual supplied with the column to determine the maximum
pressure to which you can expose the column.
You typically set the high-pressure limit to 50 to 100 psi below the normal maximum
operating pressure for the column. For more information, see the Care and Use Manual
for the column.
To prevent damage to the pump or column, the system shuts down when the system
pressure exceeds the high-pressure limit for more than 1.2 seconds or falls below the low
pressure limit for 60 seconds.
