Data logging

Data logging commences when a firing is started. Datalogging finishes when the
firing is complete and when the kiln has cooled to 100°C. A file: LOGnnn.CSV is
created on the FLASH drive. The first file to be created will be LOG000.CSV. Sub-
sequent firings will generate LOG001.CSV ... up to LOG999.CSV. Only 1000 log
files are allowed. It is best to move the LOG files to another storage disk after just
a few firings—because it takes about 1 second to index each existing file on disk
before a new file can be created. So for example if there are files LOG000.CSV to
LOG100.CSV on disk there would be a delay of just over 100 seconds before
LOG101.CSV could be created and logging could be commenced.
The files created are in "Comma Separated Variable" (CSV) ASCII format and can
be directly imported into Microsoft Excel Spreadsheets.

Logging Interval

This can be adjusted over the range 5 to 300 seconds (default 60 seconds) using
parameter P50 with the controller in configuration mode (see page 39, Parameter
Configuration).

13. Error Messages

If the ST 410 detects a problem the buzzer will sound and an error message will be
displayed. This error message will alternate with a display of kiln temperature.
The segment number display will show where the error occurred.
To obtain more information on the error operate the
display the maximum temperature reached in the firing. The second press will display
the length of time that the error has been present. The buzzer will mute.
E r r. 1 Heating error. The kiln temperature is not increasing as required. The
kiln has been on full power for 15 minutes but the temperature has
not increased by at least 2°C.
Possible causes: Kiln door or lid are not closed properly or door switch faulty or
needs adjusting. Heater element open circuit or elements too old. Electrical power
phase failure or contactor failure.
Thermocouple or thermocouple wiring open circuit. Get thermocouple
E r r. 2
and wiring checked. Replace thermocouple if necessary.
Thermocouple reversed (kiln temperature apparently less than -40°C).
E r r. 3
This is an installation fault. Get wiring checked.
E r r. 4 Cooling error. The kiln has been on zero power for 30 minutes but the
kiln temperature has not fallen by at least 1°C.
Possible causes: kiln room vent fan failure, kiln room too small, ventilation grills
blocked, damper or bung left open, controller mounted too close to kiln.
