Errors in detector
Current over
Flame error in detector
Errors related to TCD
Error related to ignition in detector
Message Meaning Solution
DET #n TCD cell error
DET #n FTD current error
(n = 1 to 4)
The current of detector is abnormal. If
the value of resistance of firmament
becomes unusually high when using
TCD or FTD, the protection circuit is
activated to prevent the filament
damage, and alarm beep sounds
continuously.
Select "Ignore Error" at first.
The following may be the reasons
why the protection circuit has been
activated.
• Set current value exceeds the
maximum operating current.
• Makeup gas is not being supplied.
• Gas is leaking.
• There has been a lot of air in the
flow line (If using TCD).
Remove these causes and select
"Reset Error" to recover the system.
In case the system is not recovered
even though you have tried quite a
few times, and you don't know the
reason, contact your Shimadzu
representative.
Message Meaning Solution
DET #n flame went out
(n = 1 to 4)
The flame in detectors (e.g. FID, etc.)
is extinguished.
Verify that gas is flowing, and re-
ignite detectors. When this error
occurs repeatedly, it is due to
hardware malfunction. You can't use
the GC as it is. Turn off the power of
the instrument, and contact your
Shimadzu representative.
Message Meaning Solution
TCD signal is out of range
TCD signal zero error
The difference of filament resistance
between TCD cells is large, which
disables zero-adjustment.
The detector control unit may have
failed. You can't use the GC as it is.
Turn off the power of the instrument,
and contact your Shimadzu
representative.
Message Meaning Solution
DET #n ignition failed
(n = 1 to 4)
This appears when the FID cannot be
ignited. Be careful, in this case, if
using manual flow controller.
Hydrogen gas will not be shut off
automatically.
Shut off Hydrogen gas for safety, and
ALWAYS observe the following.
(1) Columns are connected.
(2) Hydrogen is supplied at
appropriate flow rate.
(3) Air is supplied at appropriate flow
rate.
(4) The filament of igniter is not cut.
(5) The FID jet is not clogged.
(6) The unused hydrogen detectors
are OFF.
H2, AIR APC are not ready This appears when the APC of H2
and AIR are not turned to "Ready" at
ignition.
Verify that the gas supply pressure is
stable, and there is no leakage. If no
problem in gas supply, it indicates
that hardware is damaged. You can't
use the GC as it is. Turn off the power
of the instrument, and contact your
Shimadzu representative.
