Property/Command

Description

ActualSplitRatio

Indicates the actual split ratio of the flow splitter. A value of 1000 means that a master flow of 100 µL/min will result in a nano flow of 100 nL/min.

CardState

Reports whether the flow splitter chip card is present

NoChip

The card is missing.

DoorOpened

The front panel door is open. (The card is not writeable while the door is open.)

UnknownFormat

The card format is unknown.

BusBlocked

One of the cards is not inserted correctly. Thus, it may happen that another card is not readable although it is correctly installed.

Comment

Enter any user-specific comment text.

Description

Describes the flow splitter.

FSColPressDesired

Sets the desired pressure when FSControlMode is set to Pressure. For test purposes only.

FSControlMode

Sets the flow control operation mode. The standard operation mode is Auto. All other modes are for test purposes only.

FSFlowControllerStatus

Reports the flow control status (read-only). This includes the status of the flow sensor (see FSFlowSensorStatus) and the status of the flow splitter valve (see FSValveStatus).

OK

The flow splitter is working correctly.

PressureLow

The necessary pressure is not built up. This can be due to:

a) The flow delivered by the pump is too low.
--Or--

b) Pressure buildup is insufficient due to, e.g., leakage in the system.

Inspect the system for signs of leakage. Verify that the configuration settings match the actual system structure.

PressureHigh

There is too much backpressure, for example, because a capillary or the column is blocked.

Perform a self-test for the valve. Perform a cleaning cycle for the valve if necessary. Exchange the capillaries and/or column if necessary.

ValveFail

The flow control valve is malfunctioning. Check the valve and perform a cleaning cycle if necessary..

ValvePositionLimit

The flow control valve does not build up enough pressure. For remedial actions, refer to PressureLow and ValveFail.

FlowSensorFail

The flow sensor is malfunctioning. Turn the flow manager off and on.

RegulationErrorr

The control accuracy is insufficient. In most cases, this is due to excessive pump pressure pulsation. Make sure that the pump works bubble-free. Check the valves if necessary. .

FSFlowSensorStatus

Reports the status of the flow sensor (read-only):

OK

The flow splitter is working correctly.

SensorNotFound
TimeoutError
DataTransferError
DataIntervalError
InvalidData
DataFrameErrorr

The flow sensor is malfunctioning. (The exact wording is important only for Dionex Service.) Turn the flow manager off and on.

FSValveInit

Resets the flow control actuator; can be used to recover from malfunction (for service purposes only).

FSValveStatus

Reports the status of the flow splitter valve (read-only):

Init

The valve is initializing.

OK

The valve is working correctly.

OutOfRange

The flow splitter valve is malfunctioning. This error can correspond to the errors described in FSFlowControllerStatus. Refer to the section above for information about remedial actions.

PressureLimit

This error is also reported as PressureLow and/or PressureHigh for the FSFlowControllerStatus property. Refer to the sections above for information about remedial actions.

PositionLimit

This error is also reported as ValvePositionLimit for the FSFlowControllerStatus property. Refer to the sections above for information about remedial actions.

InitFlowControlSelfTest

Starting from zero, the flow control actuator runs a linear ramp with the specified step (StepRate; range 10-100 ms). The resulting course of the column pressure allows you to draw conclusions when an error or fault occurs.

ProductId

Indicates the product number of the flow splitter.

SerialNo

Indicates the serial number of the flow splitter.
