Energy Used Display
Pressing the
§
button at any time shows the amount of electrical energy used
in kW hours. If pressed during a firing it shows the energy used so far. After
a firing it shows the total energy used for that firing. 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 into the ST315—see installation handbook.

The keys on the ST315 can be locked so that pressing them has no effect.
This is an anti-tamper feature used to ensure that the operation of the ST315
or the program data cannot be altered by un-authorised people. The ST315
can be locked when it is idle (not firing) or while it is firing. It cannot be
locked while it is being programmed.
If the left-hand decimal point in the
display is lit then the ST315 is locked.

Power Failure Recovery
If power fails during firing then the ST315 recovers as follows:-
For power failure during start delay the ST315 commences firing immedi-
ately when power returns. For power failure during ramping the ST315 con-
tinues the ramp it was previously executing. For power failure during soak-
ing the ST315 ramps back up to soak temperature at the correct ramp rate
then applies the full soak period. This recovery scheme can be disabled if
required (see installation handbook) - the ST315 will then lock up with
FAIL
displayed and kiln off in the event of power failure.
