o
Either the temperature read from the safety sensor is higher than the maximum
permissible setpoint temperature and the deviation exceeds the safety threshold.
o
Or the difference between the temperature read from the oven sensor and the
temperature read from the safety sensor is above or below the safety threshold.
-
Position fault message: This message appears if the multi-position valve is not recognized (loss of
ID, power off or faulty) or if it fails to move to the requested position.
-
Isol.valve default message: This message appears if the isolation valve is not recognized (loss of ID,

Maintenance operations

Maintenance schedule
10.1.1
After each experiment
➢
Clean the TGA furnace with air flow about 200 mL/min.: TGA heating rate at 50 °C/min. to 1000 °C
for 30 min.
TGA must not be coupled to IST16 at this time.
➢
Clean the 1/8" stainless steel union between PTFE tube and IST16 input transfer line with solvent.
➢
Replace the Teflon
protective tube if necessary.
10.1.2
Every week
➢
Check air and water levels using the MSD signal with carrier gas flowing through IST16, in standby
mode. If the level is too high, check for leaks throughout the entire configuration.
➢
Clean the sample path of the IST16 with a
solvent (≈ 20
mL) if you don't use a Teflon
protective
tube.
10.1.3
Every month
➢
Check the glass liner state in the GC injector.
