Software Status Bulletin
78xx Driver Software 7890A
Known Problem Report as of Oct 26 2011 11:08AM
Preface
-------------------------
This Software Status Bulletin (SSB) documents all known problems in the software
product designated above. The SSB is derived from Known Problem Reports (KPR)
which result from user problems that have been classified as documentation
problems or software defects. When a KPR is written, an identifying number is
assigned to it, and the KPR is added to the next edition of the SSB.
User inputs that have been classified as Enhancement Requests are not documented in the SSB. User problems that have been submitted, but that have not been classified by the time the SSB is generated are not included in the SSB.
How to use the SSB
-------------------------
When you experience a problem with a product, first check this SSB to see if the
problem has been reported already, and if there is a temporary workaround
available for the problem, or if the problem has already been fixed by a new
revision. If the problem is not listed in this SSB then you may wish to report
it to the Response Center or to your field support representative.
To determine if your problem is documented in this SSB, first look in the "Keyword Index" section of the SSB. Under each keyword is a listing of one-line descriptions of related KPRs. If any of these sound like yours, locate the KPR # in the "Known Problem Reports" section of the SSB, and read the full KPR. The KPRs in the "Known Problem Reports" section are sorted by KPR #.
There are two sections in the SSB:
Keyword Index: This index is categorized by keyword. For each KPR there is a
brief description and a KPR #. A KPR may be associated with more than one
keyword.
Known Problem Reports: This section contains KPRs, with all the available information relevant to the problem. KPRs in this section are sorted by KPR #.

The GC status and instrument actuals list the signal value as 0.0 but does not provide feedback if the flame is out.Temporary Solution:
n/aFix Information:
Fixed in 78xx driver revision 4.02[001].
If PCM is configured with the inlet heater as PCM A or PCM B controlling the column flows/pressures, the temperature and pressure/flow setpoints cannot be set. CS shows a septum purge value and the instrument goes into shutdown, due to "septum purge not ready".Temporary Solution:
n/aFix Information:
Fixed in 78xx driver revision 4.02[007].
A sequence was run using auto zero at the beginning of each run. At run 4 in the sequence, autozero did not occur. This is due to a firmware issue wherein only 15 signal events (including auto-zero) would be processed before failure. The number 15 is cumulative since the last reboot which means that after 15 runs, the signal event will not be done.Temporary Solution:
n/aFix Information:
This issue is fixed in 7890A firmware revision A.01.12.1.
Barcode heater range is 0 - 80 °C. Software tooltip shows range of 0-400°C, and software accepts values up to 400 °C.Temporary Solution:
n/aFix Information:
Fixed in driver revision 4.02[008].
User makes a manual injection and waits until the peaks of interest elute, then hits the STOP on the 7820 front panel the GC stops (and resets the initial GC settings) but the chemstation continues and reports the system is running data analysis but does not go into data analysis. System appears to hang up waiting on the expected run time and report is generated at that point rather than directly after STOP is pressed.Temporary Solution:
Use STOP run from the software.Fix Information:
Fixed in driver revision 4.02[11]
Run Log entries (i.e. oven door opened) occurring during a run remain in the logbook until the restart of the GC.Temporary Solution:
n/aFix Information:
Fixed in GC FW A.01.12.1.
Saved a method. Open the GC edit parameters to review a setpoint and made no changes or changed the view. Selected OK and the method modification flag indicates a change was made. No changes were made.Temporary Solution:
n/aFix Information:
Fixed in 78xx driver revision 4.02[019].
In the BF Wizard at the Perform Preliminary Run page the acceptable vial range is stated as 1-100. The correct vial range is actually between 1-150.Temporary Solution:
n/aFix Information:
Fixed in 78xx driver revision 4.02[007]
The LTM column's equilibration time is shown as 0. Change the equilibration time by entering 0.5 and downloading the method. This does not change the value at the GC.Temporary Solution:
n/aFix Information:
Fixed in 78xx driver revision 4.02[005] and GC FW revision A.01.13.
The diagnostic signal can be selected for the LTM actual temperature. Upon download and upload it is returned as oven temperature.Temporary Solution:
n/aFix Information:
Fixed in 78xx driver revision 4.02[007].
Open the instrument parameter from GC Instrument Diagram and confirm sample prep is off. Set inlet heater - save changes. Open the instrument parameter from the GC Instrument Diagram and confirm sample prep is off. Change the inlet heater temp and save as a new method. Load the new method - a configuration mismatch message is displayed. Requires Easy Sample PrepTemporary Solution:
n/aFix Information:
Fixed in 78xx driver revision 4.02[004].
After modifying and saving the method the injector screen will not accept the syringe size of 10 uL. The menu will pull down and 10uL is accepted but when the screen is OK'ed the size changes to blank.Temporary Solution:
Enter the syringe size from the GC front panel, upload the configuration and save the method.Fix Information:
Fixed in 78xx driver revision 4.02[019].
After making a change to an LTM ramp, switch to a different LTM subtab or oven subtab. When user goes back to the original LTM subtab the change is gone and everything has reverted to the initial settings.Temporary Solution:
Make a change to an LTM ramp; and then switch to a different main tab (signals for example).Fix Information:
Fixed in driver revision 4.02[001].
The monitoring of the GC realtime plots will show signal events defined in the method even if the method is not running.Temporary Solution:
n/aFix Information:
Fixed in 78xx driver revision 4.02[005].
Create a method with more than 15 digital signal events. Error message notifies user that there are too many events, but events cannot be deleted. Method with too many events can be saved, but then cannot be loaded into the method editor. Loading a new method results in an error message asking to save the invalid method and notes that there are too many signal events.Temporary Solution:
n/aFix Information:
Fixed in 78xx driver revision 4.02 [004].
Enter a new pressure on the PTV inlet. The number is not accepted, the value reverts back to the existing value.Temporary Solution:

When the outlet of the column configuration is set as "Other", there is no backflush icon displayed in the 7890 Edit Parameter Screen.Temporary Solution:
n/aFix Information:
Fixed in 78xx driver revision 4.02[009]. When the configuration is changed from backflush not available to backflush available, the user must exit the method editor and begin the edit a second time in order for the backflush icon to be shown.
With the GC in shutdown mode method download is not allowed. If OK or apply are selected when the GC is in shutdown mode, method download begins, the driver disconnects, and then reconnects causing the GC to go offline.Temporary Solution:
n/aFix Information:
This is fixed in driver revision 4.02[009].
If you run Backflush from Chemstation with segmented columns (usually associated with LTM), only the in-segment portion of the configuration is used in the backflush flow rate and void volume calculations. This leaves the user unable to calculate the backflush time.Temporary Solution:
n/aFix Information:
Fixed in driver revision 4.02[023].
In the Edit Parameter screen for the oven and the inlets, the display of this screen is small. Adjusting the method setup screen will not resize this screen.Temporary Solution:
Right click on parameter setting screen, and go to "show graphical plots". The display will resize to a normal size.Fix Information:
Fixed in 78xx driver revision 4.02[006].
After editing the GC method and selecting ok, a "Validation Error" error message flashes in the left hand corner of the screen. User must select cancel to exit the GC parameter screen.
