Other Features
Energy Used & Setpoint Displays
Press and hold down the
function
key then
press
the ◄ key at any time to show the
amount of electrical energy used in kWh.
During a firing the energy used so far is
shown. After a firing the total energy used for the firing is shown. This infor-
mation 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 Installation section.
Operating the ◄ key a second time shows the current set
-
point (the temper-
ature which the ST535C is currently trying to achieve).
Keyboard Lock Facility
The keys on the ST535C can be locked so that pressing them has no effect.
This is an anti
-
tamper feature used to ensure that the operation of the
ST535C or the program data cannot be altered by un
-
authorised people.
The ST535C 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 ST535C recovers as follows:
-
For power failure during start delay the ST535C times off the remaining start
delay when power returns. For power failure during ramping the ST535C
continues the ramp it was previously executing. For power failure during
soaking the ST535C 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 section)
-
the ST535C will then lock up
with FAIL displayed and kiln off in the event of power failure.
Press and hold the
function
key down for 5
seconds to lock or to unlock.
