FE #
- Fatal software Errors, FE Alarms indicate a hardware failure or software
problem with the controller. These alarms will disable the normal controller
operation and require corrective action. If a Fatal Error occurs during an active
firing, the firing is terminated. These alarms include;
FE 1
– Failed to read or write to memory device
FE 2
– Failed memory test during power on
FE 3
– Corrupt data found in memory
FE 4
– Errors detecting thermocouple input signal
FE 5
– Software Execution failed
Turn the controller off and back on, then press any button to try and clear the
alarm. If the alarm reoccurs immediately or frequently, the controller may require
service or replacement.
FE 4
alarms can often be solved by correcting problems with the system thermocouple.
Loose connections or faulty thermocouple wiring or a faulty thermocouple can result in
this alarm.

Special Note
If your kiln is set up in an unheated area, and is left idling overnight, and the
room temperature has dropped to, say, 20 degrees, you may see an alarm code
TcR
(thermocouple reversed) when you attempt to run a new firing in the
morning. Merely shut off the kiln and re-start. Things should then function
normally.
