Command/Property

Description

AnalogOut

Determines whether the pressure of the left or right pump is monitored via the Analog Out port on the pump (available for pumps with firmware 2.50.05 or higher).

CamRevolutionsRight
CamRevolutionsLeft

Indicates the number of revolutions of the camshaft of the right or left pump block. The CamRevolutionsLeft command is available for HPG pumps only.

Curve

Determines the curvature for flow gradients (see Gradient Curves).

Degasser

Turns the solvent rack degasser On or Off (P680A LPG-4, SOR-100, or SRD-3x00 only). The integrated degasser should always be on.

DegasserVacuum

Reports the status of the solvent rack degasser (P680A LPG-4, SOR-100, or SRD-3x00 only): OK or NotOK (read-only; available for pumps with firmware 2.03 or higher).

HeadType

Indicates the head type of the pump: Analytical or Semi-Prep (read-only).

Leak

Indicates the status of the central leak sensor: OK or Leak (read-only).

LeakAlarm

On indicates that there is a leak alarm (read-only; available for pumps with firmware 2.50.05 or higher).

LeakAlarmOff

Turns off the acoustic beep for the current alarm (available for pumps with firmware 2.50.05 or higher).

LeakDelay

Specifies how much time elapses between the detection of a leak and the pump shutdown (available for pumps with firmware 2.50.05 or higher).

LeakSensorMode

Specifies how leak detection is performed:
Enabled-Enables leak detection; an acoustic beep sounds when the leak sensor is activated.
Silent-Enables leak detection; no beep sounds when the leak sensor is activated.
Disabled-Disables leak detection.

MaximumFlowRamp

Specifies the upper limit for the flow rate acceleration
(0.1 - 10,000.00 ml/min²).

ModelVariant

Indicates the variant: Isocratic, LPG, or HPG (read-only).

Motor

Indicates whether the pump is delivering: On or Off (read-only).

Pump_Pressure

Commands and properties for the pressure signal (see below).

Purge

Enables purging when set to On (available for pumps with firmware 2.50.06 or higher).

PurgeFlow

Enter the flow [in mL/min] to be delivered by the pump during purging (range: 0.000 to 10.000 ml/min or 20.000 ml/min for HPG pumps with enabled Double Flow option; available for pumps with firmware 2.50.05 or higher).

PurgeTime

Specifies for how long purging is performed (0 - 1000 s) (available for pumps with firmware 2.50.05 or higher).

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 met, a message is displayed in the Audit Trail and on the pump.

RearSealWashPump

Indicates whether the peristaltic pump of the rear seal wash system is running (Active) or not (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. However, the drop sensor on the liquid reservoir is not active, i.e., the piston seals are not monitored for tightness.

Automatic-Periodically activates rear-seal washing once per hour until the drop sensor has counted 50 drops. The drop sensor is active, i.e., the piston seals are monitored for tightness.

Off-Turns the rear-seal wash system off.

SelfTest

Performs a self-test to check that all main components are functioning correctly.

SelfTestPassed

Reports the results of the self-test (read-only). If the pump fails the test, eliminate the cause of the error and/or fault. For troubleshooting help, refer to the operator's manual for the pump.

SolventRackLeak

Reports whether the leak sensor in the solvent rack detected a leak: Leak or NoLeak (read-only; available for pumps with firmware 2.03 or higher).

WorkLoadLeft

Indicates the workload of the left pump block in [MJ] (read-only). The WorkLoadLeft command is available for HPG pumps only.

WorkLoadRight

Indicates the workload of the right pump block in [MJ] (read-only).

AcqOn/AcqOff

AcqOn starts data acquisition. AcqOff terminates data acquisition.

Average

Averages all measured values.

Delta

Reports the signal's slope, i.e., the difference between the value and the value 1 second ago (read-only). This is useful for Triggers.

MaxAutoStep

Sets the maximum step rate for Step = Auto.

Retention

Indicates the retention time for the signal.

Step

Sets the step for data acquisition.

Equilibration

Reports the equilibration status.

Ripple

Reports the ripple of the pump pressure.

UpperLimit

Determines 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%.

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.
