The overtemp message happens when the ANKOM HCl Instrument is heating but there is no solution in the vessel. The quartz heaters will heat the vessel and the ETS (Emergency Temperature Switches) will trip.

Possible Causes:

Instrument was not properly filled- make sure the acid was put in the instrument and that the water supply is on.

There is a filling or draining problem-To investigate, run the following test:

  1. Add 500ml of water to the vessel and run a 60 minute hydrolysis.
  2. Check the water level every 5 minutes during the hydrolysis to make sure that the water has not boiled away or that the water has not drained from the may have a leak.
  3. After the hydrolysis, make sure the solution completely drains and the heat is off.
  4. During the first rinse step, make sure the vessel has been automatically filled with water. If this does not occur, the water valve may not be functioning. Contact ANKOM for assistance.
  5. Check the water level during the rinses and make sure the water only drains during the "Drain Cycle"
  6. If this test does not provide answers, contact ANKOM Tech Support with your results.

To best assist you, it is helpful to know the following:

  • Does this fault occur every time?
  • When does the fault occur?
  • How many minutes into the hydrolysis?
  • How many minutes into the rinse?
