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.
