Waters 600e - Setting External Event Switches

170 Running Gradient Controller in Isocratic Mode
Sparge
Determines the rate at which the system sparges the eluent reservoirs.
To set the sparge rate value:
1. Move the cursor to the Sparge field.
2. Type the appropriate sparge rate value (0 to 100 mL/min). Press Enter.
Note: The system uses the same sparge rate for all eluent reservoirs that you enable on
the Pump Setup screen. Use an initial high sparge flow rate and then reduce it to a low
maintenance rate. The sparge method you use depends on your analytical requirements.
See Appendix B, Eluent Considerations, and Chapter 3, Preparing Your 600E System for
Operation, for more information.
Temperature
Controls and maintains a stable column-operating temperature. This value must be less
than or equal to the high-temperature limit programmed on the Pump Setup screen (see
Section 8.2.3, Exiting the Pump Setup Screen). The range of temperature within which the
column heater can operate is listed on the module label.
To set the column heater temperature:
1. At the Temperature field, type the appropriate temperature in °C for the analysis you
want to run.
2. Press Enter.
Note: Verify separation methods requiring elevated temperatures at the elevated
temperatures. If no column heater is installed, the Temperature field contains a value of
None.
9.1.2 Setting External Event Switches
S1, S2, S3, S4
The Isocratic screen (see Figure 9-2) allows you to manually operate external devices by
setting the S1 through S4 external event switch parameters.
Use the S1 through S4 event switch terminals on the controller rear panel to control
devices such as fraction collectors, switching valves, or other non-PowerLine
components.
