# Text Description Action
371 ! Invalid channel acquisition
overlap on %3
Two channels referencing the same
hardware detector are scheduled to ac‐
quire at the same time.
If multiple application detector channels
are assigned to the same hardware de‐
tector, do not allow their times to over‐
lap.
372 ! Scheduling error %3 scan‐
ning %4 # %5 channel %6
Unable to schedule all event and polling
routines. May indicate a memory or hard‐
ware failure.
If method schedules many events as
well as all 18 detectors, try removing
some of the events or deleting some of
the detectors, then resetting the SNE.
373 ! Module I/O error %3 on %4
# %5 channel %6
Error between module and channel. Indi‐
cates obsolete anayler.
Consider upgrading analyzer.
374 ! Internal communication er‐
ror %3
Software modules inside SNE are failing
to communicate. Usually happens with
out of memory condition resulting from
SYSCON timeout.
Reduce processing requirements on
SYSCON.
375 ! End of cycle missed; stop‐
ping cycle
The message that coordinates the end of
a method around the SNE tasks was lost.
Reset SNE.
Reduce the complexity of the SNE set‐
up.
Replace SNE.
376 + Adjusting cycle clock mas‐
ter
Obsolete software version. Contact Customer Support.
377 ! Error %3 scheduling cycle
clock master adjustment
Resource not found for scheduling ad‐
justment of event clock. SNE may be
overloaded.
Reduce complexity of tasks for
SNE.Reset SNE to prevent event clock
overflow.
378 + %3 samples adjusted on
chrom from channel %4
An excessive number of samples re‐
quired adjustment on chromatogram. Oc‐
curs in conjunction with DPM alarms.
Replace affected DPM.
379 ! Error %3 preparing analy‐
sis for channel %4
EZChrom processing error. Check integration events; modify
events that may cause problems.
380 ! Error %3 finding chrom
peaks for channel %4
EZChrom processing error. Check integration events and peak ta‐
ble; modify events that may cause prob‐
lems.
381 ! Error %3 generating re‐
sults for channel %4
EZChrom processing error. Example er‐
ror: Setting the threshold value too low,
causing many peaks to be detected in
the noise of the chromatogram.
Check method for problems that could
affect results.
382 ! EZChrom server failed er‐
ror %3 on channel %4
Resource problem on SNE. Reduce SNE workload.
Replace SNE.
383 ? Software Watchdog Time‐
out
SNE is running out of processing capaci‐
ty.
Reduce SNE workload.
Replace SNE.
384 ! Method Modification Failed An attempt to modify a running method
failed, most likely due to invalid data.
Verify that modification was valid.
385 ? Event occurred before
modification request
Before a modification of a running meth‐
od was completed, the event occurred.
Contact Customer Support.
386 ! Invalid Cycle Length %3 A cycle length larger than the maximum
size was specified in a method. Usually
caused by a corrupt method. Maximum
cycle length is approximately 2 days.
Verify correct values in method.
387 ! Invalid Sample Rate %3 on
channel %4
Invalid sample rate value chosen for
channel in method.
Verify the methods and use only a sup‐
ported detector sample rate.
