energy used so far is shown. After a firing the total energy used for
the firing is shown. This information is stored while power is off and is
only reset to zero when a new firing is started. If the value displayed
is always 0.0 then the kiln power rating has not been configured (see

Keyboard Lock Facility
The keys on the ST 630 can be locked so that pressing them has no effect. This is
an anti-tamper feature used to ensure that the operation of the controller or the
program data cannot be altered by unauthorised people. The ST 630 can be locked
when it is idle (not firing) or while it is firing. It cannot be locked while it is being
programmed.

Power Failure Recovery
If power fails during firing, then the controller recovers as follows: for power failure
during start delay the controller times off the remaining start delay when power
returns. For power failure during ramping the controller continues the ramp it was
previously executing. For power failure during soaking the controller 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 – the controller will then
lock up with FAIL displayed and kiln off in the event of power failure.
