KILN OPERATION DURING A FIRING
At the start of a firing, the controller sets its traveling set point to the current
temperature in the kiln. The traveling set point is where the controller wants the kiln
temperature to be. The controller will then move the traveling set point up at the
programmed rate and cycle power to the elements to make the temperature follow the
traveling set point. You will hear the relays clicking to regulate the kiln temperature. The
elements will receive power when the temperature is below the traveling set point. The
relays will click off when the temperature is above the traveling set point. The current
segment and traveling set point can be viewed by pressing the up arrow during a firing.
Options During Firing

a firing the current ramp or hold is displayed followed by the current or traveling set-point, then
"SStP" is displayed. If you do not press a key within several seconds the display will return to
showing the current temperature in the kiln.

Add Time to Hold Period
Available only during a hold period This option allows you to add time
in 5 minute increments to a hold (soak) period. When in a hold period (during a hold or soak, the
temperature in the kiln will be alternating in the display with the remaining hold time), press the
UP key. When "SStP" is displayed press the UP key again and "tME" will be displayed. Press
ENTER and 5 minutes will be added to the hold time. You may use this procedure as many
times as necessary to get the hold time that you want.
