3 Known issues
Configuration￭￭

Metrohm IC modules cannot be combined with Agilent LC modules. For
example, an Agilent HPLC cannot be combined with a conductivity detector.
Metrohm IC Driver for OpenLab cannot detect, whether an
858 Professional Sample Processor contains a stirrer. The stirrer can be activated or deactivated in manual configuration.
It is possible to configure a stirrer even though the instrument does notcontain a stirrer. It is possible to define parameters for the configured but
inexistent stirrer in the method or in manual control. It is possible to run amethod with these parameters or to switch the stirrer on in manual control.

Status panels
￭

￭

￭

￭

The instrument status is displayed in the status panels and at the bottom of
the dashboard. During initialization, the status panels display Not Readybut the dashboard already displays Instrument Idle. If the status panels
and the dashboard display a different status, then the status of the status
panels is relevant.
An [On] button is located at the bottom of the Dashboard. This button
has no functionality for Metrohm instruments. You cannot start the instrument with [On]. To start the instrument, send a method to the instrument
or start units in manual control.
The same applies for the [On] and [Off] buttons on each status panel.
The status Injecting is not available for the858 Professional Sample Processor and the 889 IC Sample Center. In aninstrument that contains an IC and an autosampler, the autosampler is instatus Run while the IC is in status Injecting.
In the MSM start parameters, the dosing rate for dosino regeneration iscalculated from the parameters Volume and Time.
If you send the current method to the instrument to equilibrate the instrument, then the default dosing rate of 1.0 mL/min is applied for the first
MSM step. For all following MSM steps, the dosing rate from the method isapplied.

Data acquisition￭

2

The moment when a time program starts measuring is displayed with a redline in Online Signals. If 2 detectors of a 2-channel instrument startmeasuring at a different time, then the following behavior applies: In thecharts for the conductivity detectors, both of these moments are recordedat the same time. Actually, only the measurement for the first detector
starts at the recorded time. The measurement for the second detector starts
later.

In the display of live data is sometimes interrupted while the instrument is in
the status Injecting. As soon as the instrument enters the Run status, live
data is displayed correctly again. This behavior does not affect the measurement.
In Online Signals, it is possible that the time axes of different signals donot coincide.
The combination of Dose-in gradient and Dosino regeneration MSM leads
to random aborts. An error with the message Executing Dosino command “Dose-in gradient” during execution of time program failedoccurs. Data acquisition stops. The next line in the sequence is executed.

8.0102.8007EN / v7 / 2024-07-31

If the configured instrument contains fewer modules than the instrumentfrom the loaded method, then the entire modules are removed from themethod without notification.
If you use a method with time program as a shutdown method, then thetime program is executed in the shutdown method. Time program commands that use information from the sequence cannot be used in the time
program of a shutdown method.
Do not use the following commands in the time program of a shutdown
method:– Dosing unit commands – Volume mode: Injection volume– Dosing unit commands – Volume mode: Injection volume next sample– Move – Position type: Vial from Sequence– Move – Position type: Next Vial from Sequence– Move – Position type: Vial from Sequence +1– Event Wait
With the command Parallel it is possible to execute several time programcommands at the same time. If the same unit is used for several commands
at the same time, an error is generated, but not all units are stopped.
The position type Next Vial from Sequence of the 889 IC Sample Centercan only be used if the next sample uses the same acquisition method as
the current sample. Ensure that the sequences in the sequence table meetthe requirements for the Next Vial from Sequence command.
The position type Next Vial from Sequence cannot be used with the858 Professional Sample Processor. An instrument error occurs and thesequence is aborted.
With instruments with a detector, it is not possible to execute a run without
data acquisition. Always add a measure command to the time program.
Otherwise, the instrument stays in the state Injecting and does never enter
the state Run.
If you do not want to acquire data during the run, then add a time programcommand Measure Conductivity at the end of the time program anddefine a recording time of 0 minutes. As different detectors in an instrument can have different recording times, ensure that the recording time foreach detector is properly adapted.
If an instrument does not contain a conductivity detector, then the instrument enters the Run state with the first acquisition command. In this case,the command Measure Conductivity is not needed.

The translation is incomplete. If you create a time program and delete multiple lines, the appearing window contains the keys [Ja] and [Nein].
The input range of the intensity level for the 947 Professional UV/VIS Detector Vario is 2 … 12.
If you enter a value that is > 8, a warning icon is displayed. Despite thewarning icon, it is possible to set intensity level values up to 12. Ignore thewarning icon.
In an instrument with a 944/947 Professional UV/VIS Detector Vario and an
858 Professional Sample Processor, connection problems may occur.
If you close the instrument connection, update the firmware revision andlaunch the instrument again, the firmware of the instrument modules is not
displayed under Report ▶ Instrument Information ▶ Instrument
Modules.
The reason for this behavior is an OpenLab bug (Tracking Number:
CDS2ACQ-14753 306156).
If a module is in Error state and you send a method to the instrument, itmay occur that the module remains in Error state, but some units of themodule work correctly.
