Power Failure Recovery
If power fails during firing then the ST535 recovers as follows:
For power failure during start delay the ST535 times off the
remaining start delay when power returns.
For power failure during ramping the ST535 continues the ramp it
was previously executing.
For power failure during soaking the ST535 ramps back up to soak
temperature at the correct ramp rate then applies the remaining
soak period.
This recovery scheme can be disabled if required (see installation
handbook) - the ST535 will then lock up with FAIL displayed and
kiln off in the event of power failure.
6.14 Error Messages
If the ST535 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
◄
key. The
first press will display the maximum temperature reached in the
firing. The second press will display the length of time that the

Please keep a note of the above mentioned information as it will be
needed in case you contact our technicians.
