7.2 Temperature Control
The temperature does not rise, or does not agree with the setting.
Cause Countermeasure
Overheating was detected and an error
was generated.
Check for burnout in, and check the EMF of, the oven
thermocouple. If either of these is the cause of the error, replace
the oven thermocouple.
The EMF at both ends of the thermocouple connector is equal to
40 V multiplied by the difference, measured in C, between the
local temperature and the ambient temperature.
The column's set temperature is higher
than the detector's set temperature.
The software automatically ensures that the column temperature
does not exceed the detector temperature.
Set the detector's set temperature higher than the column's set
temperature.
The sample injection unit or the detector is
not set to line configuration.
Temperature control is not possible for units not set to line
configuration.
Set the corresponding unit to line configuration.
7.3 Detector
7.3.1 FID
1. Ignition is not possible.
Cause Countermeasure
The igniter filament has burnt out.
Replace the igniter. (Refer to 4.11.2 Maintenance Procedures in
the Operation Manual.)
There is a fault in the igniter circuit.
Check the voltage at both ends of the connector (between 1 (+)
and 2 (-) of CN2) at ignition with the igniter filament connected.
If a DC voltage of approx. 2 V is not output approx. 10 s after
"Ignition started" or "Ignition is retried" is displayed, then there is
a fault in the ignition circuit. Replace the FID control board.
The nozzle is clogged with the sample or
the graphite ferrule residue.
Clean (using, for example, CLEANING WIRE, 201-79229-01) or
replace the nozzle. (Refer to 4.11.2 Maintenance Procedures in
the Operation Manual for details on mounting and removing the
nozzle.)
2. There is a lot, or a high level, of noise.
Cause Countermeasure
The collector is dirty.
After removing the igniter, clean the metal portion of the collector
in a liquid such as hexane. (Refer to 4.11.2 Maintenance
Procedures in the Operation Manual for details on mounting and
removing the collector.)
The H
2
flowrate is fluctuating. Replace the APC.
