830 Warning Codes
A Warning message alerts the operator that a problem exists, but that the
problem will not prevent the instrument from executing the run. The 6890
GC emits one beep and a Warning message appears on the display. The 6890

warning is not recorded in the run log.
The tables present the messages numerically according to the popup message
number. Warning conditions generate additional information that appears in

Warning 100—Oven sensor missing
Status message: Oven sensor missing
The oven sensor is not being detected because it is unconnected or is
malfunctioning. The oven will be shut off, and the GC will be not ready.
Connect or replace the oven sensor.
Warning 101—Invalid heater power for front detector, inlet, and aux 1
Warning 102—Invalid heater power for back detector, inlet, and aux 2
Status message: Invalid heater power
The total wattage for the front or back detector, front or back inlet, and aux
1 or aux 2 heated zones exceeds the maximum wattage allowed (220 Watts).
This is only checked at power on. Either there is an invalid heater wattage
combination or the wattage sense circuit on the main board is defective.
It is unlikely that this error will occur unless a mass selective detector or
other add-on instrument is being used with the 6890 GC.
A warning is issued and the three heated zones are set to not installed.
