SPd - Firing Speed Default Setting: Std
The SPd feature adjusts how fast the kiln fires to compensate for the load in the kiln. Adjustments are made to
the normal firing programs (refer to pg. 25 - Preset Cone Firing Programs). Slow settings can be used for heavy
loads and the fast settings for light loads. Speed is applied only to increasing ramps and not to dwells (soaks).
Speed does not apply to the last ramp of a cone firing. Firing Speed can only be modified during program setup,
not during an active firing cycle. The Firing Speed choices are given below:
Display Description
Std Standard cone firing program
S 10 Slow; increase firing time by 10%; decrease firing rate by 10%
S 20 Slow; increase firing time by 20%; decrease firing rate by 20%
S 30 Slow; increase firing time by 30%; decrease firing rate by 30%
S 40 Slow; increase firing time by 40%; decrease firing rate by 40%
F 10 Fast; decrease firing time by 10%; increase firing rate by 10%
F 20 Fast; decrease firing time by 20%; increase firing rate by 20%
F 30 Fast; decrease firing time by 30%; increase firing rate by 30%
F 40 Fast; decrease firing time by 40%; increase firing rate by 40%
NOTE: The Firing Speed adjustment is a permanent change to be applied to all future firings
unless reset by user.
This setting does not automatically reset itself. This feature is different from the earlier
versions (prior to 0030), where Firing Speed Adjustments were reset to Standard after each firing.
ProG - Program Review
The ProG feature enables the user to review the current firing cycle of a preset cone program or a user program.
The user cannot change the program while in this option. When selected, the option defaults to the current
program segment.
For preset cone programs, Program Review alternately displays the preset cone number and the corresponding
cone deformation temperature at the 108
°
F/hr rate (60
°
C/hr).
SStP - Skip Step
The SStP feature allows the user to end a hold or a ramp during an active firing cycle and skip to the next
program ramp. This is useful if a user wants to watch the firing to visually decide when to make a change, such
as when glass is slumped. The Skip Step applies to User programs only and not to the preset cone fire
programs.
If the current step is a ramp then it will skip to the next ramp step and continue to ramp at the new rate.
If the current step is a dwell then it will skip to the next ramp step and continue to ramp to the next temperature.
If the current step is a ramp recovery step (after power loss, recovering to the prior dwell temperature), then it
will skip to the next dwell step and dwell at the current temperature for the remainder of the unfinished dwell
time.
