Dionex DP/SP Pumps
In addition to the standard pump commands (see Dionex Pumps), the DP/SP pumps support the following commands and properties (please note that the display Filter level determines which commands and properties are displayed):
Command/Property |
Description |
CamRevolutionsLeft |
Indicates the number of revolutions of the camshaft of the left or right pump block. |
Degasser |
Turns the integrated vacuum degassing module on or off. The degassing module normally remains on at all times. |
HeadType |
Indicates the head type of the pump: Analytical or Semi-Prep (read-only). |
Leak |
Indicates the status of the main leak sensor: OK or Leak (read-only). |
MaximumFlowRamp |
Upper limit for the flow rate acceleration: |
ModelVariant |
Indicates the variant: Isocratic or Gradient (read-only). |
Motor |
Indicates whether the pump is delivering: On or Off (read-only). |
RearSealLeakCounter |
Indicates the number of drops that passed the piston seal in the past hour. |
RearSealLeakLimit |
Specifies the leak detection threshold for the rear seal wash system. If the limit is reached, a message is displayed in the Audit Trail. |
RearSealWashPump |
Indicates whether the peristaltic pump of the rear seal wash system is running (Active) or not running (Idle) (read-only). |
RearSealWashSystem |
Turns the rear seal wash system on (Interval or Automatic) or Off. Interval activates rear-seal washing for 5 minutes every hour. During this time, the drop sensor on the liquid reservoir is not active, i.e., the pistons seals are not monitored for tightness. Automatic periodically activates rear-seal washing once per hour until the drop sensor has counted 50 drops. During this time, the drop sensor is active, i.e., the piston seals are monitored for tightness. Off turns off the rear-seal wash system. |
WorkLoadLeft |
Indicates the workload of the left pump block in MJ (read-only). |
WorkLoadRight |
Indicates the workload of the right pump block in MJ (read-only). |
ER Controller Commands (RFIC-ER systems only)
The controller commands are described in Dionex ER Controller.
Equilibration Commands and Properties
Tip:
Use the equilibration commands and properties only for the SmartStartup feature.
Equilibration |
Reports the equilibration status (OK or Not OK). |
|
Ripple.UpperLimit |
Sets the upper limit for the ripple of the pressure signal in [%]. The upper limit can be any value between 1.0% and 5.0%. The default setting is 3.0%. |
|
Ripple.Value |
Reports the actual value. The value is calculated as soon as at least a one-minute segment was measured. It is updated with each new recorded segment and averaged over the last 5 minutes. If the average pressure is below 10 bar, the ripple measurement is started again. The value of the property does not change after the measurement and is displayed under Preconditions. |
|
RippleStatus |
Reports the ripple equilibration status of the pump pressure (read-only). |
|
N/A |
Equilibration has not started. |
|
Measuring |
Equilibration is running, but the amount of data is not yet sufficient to report a result. |
|
Good |
Equilibration is running or has finished. The values are within the specified limits. |
|
NotReady |
Equilibration is running. The current data is outside the specified limits. |
|
Failed |
Equilibration is completed. The result is outside the specified limits. |
|
NotTested |
The limit was set to 0, thus disabling ripple checking. |
|
StartEquilibration |
Starts equilibration. For more information, refer to How to ...: Equilibrating the Chromatography System. |
