== Kiln Trained Users ==<br />
<br />

<br />
== KilnZone Rules ==<br />
<br />
1) I3 KilnZone training is required to operate KilnZone equipment. A list of Trained Users is below.<br />
<br />
2) When not firing, all private materials and components need to be removed to member's storage. The metal rack is for PUBLIC materials only.<br />
<br />
3) Use Boron Nitride for public molds. Use Kiln paper for Kiln floor.<br />
<br />
4) Clean or apply KilnWash or Boron Nitride OUTSIDE. No Exceptions. ALWAYS use a mask. <br />
<br />
5) When using glass powder and other materials of 100 Micron or less, use a mask. And don't work near other people. (Farther than 20' and near ventilation if possible).<br />
<br />
6) Do Not open a working Kiln unless you are the current user or there is an emergency.<br />
<br />
6) If you are using a Kiln and need to leave the building, Make sure Your name and cell # is on the KILN IN USE Whiteboard and the Kiln In Use Side is outward.<br />
<br />
7) Do not put cardboard or paper in the cage. Plastic is OK if more than 18" from the Kiln.<br />
<br />
8) ABSOLUTELY NO FLAMMABLES OR PRESSURIZED CONTAINERS IN THE CAGE.<br />
<br />
<br />
<br />
== IN CASE OF EMERGENCY ==<br />
<br />
1) If needed call 911.<br />
<br />
2) If possible and effective, turn off Programmable Controller with green switch.<br />
<br />
3) Else, if possible turn OFF Kiln 1 by turning all 3 knobs on Kiln 1 to ZERO. You should hear a click and see the red light go out.<br />
<br />
3) To contain fire, if necessary, use the fire extinguisher located at KilnZone.<br />
<br />
4) Call current user at the cell number located on the clip board on the gate of the KilnZone.<br />
<br />

==How to Program the Kiln Controller==<br />
<br />
Ver 1.0<br />
<br />
by Terry W.<br />
<br />
<br />
<br />
Step 1) Turn ON controller with Green button. You should see the current temp in PV display.<br />
<br />
Step 2) Push the SET button. You should see PASS in the PV display and 0000 in the SV display.<br />
<br />
Step 3) Our convention will be > for the rightward arrow button, ^ for the upward and v for the downward, since I can't type that one. Use >, ^, and v to type in 2000 and hit SET.<br />
<br />
<br />
<br />
Firing Schedules.<br />
<br />
You will see in books on glass, things called firing schedules. They look like this:<br />
<br />
<br />
<br />
<br />
You read that as a set of instructions:<br />
<br />
Ramp up the temperature from room temp to 1250F at a rate of 300F per hour.<br />
<br />
THEN hold 1250F for 30 minutes.<br />
<br />
THEN ramp from there to 1420F at a rate of 300F per hour.<br />
<br />
THEN hold it for 30-60 minutes.<br />
<br />
THEN ramp as fast as you can from there to 960F<br />
<br />
THEN hold it for 90 minutes<br />
<br />
THEN ramp at 50F/hr to 800F<br />
<br />
SKIP holding it.<br />
<br />
THEN ramp at 100F/hr to 600F<br />
<br />
THEN turn it OFF and don't open the kiln until Room Temp (No Venting).<br />
<br />
<br />
Your Kiln Controller needs to be programmed in a series of steps. Each steps has 3 attributes, C,T,Sv.<br />
So your list of instructions will look like<br />
<br />
C1,T1,Sv1<br />
<br />
C2,T2,Sv2<br />
<br />
C3,T3,Sv3<br />
<br />
.<br />
<br />
.<br />
<br />
.<br />
<br />
<br />
Let me define what each of those are.<br />
<br />
C is the PID setting we use. We always use PID#1, which I have preprogrammed into the controller. Please do NOT change PID#1.<br />
<br />
T is time, in minutes. More later.<br />
<br />
Sv is a target temperature in F. I believe Sv is short for “Set Value”. And Pv is Present Value....of what you are trying to control, in our case Temp F.<br />
<br />
<br />
So from our example<br />
<br />
C1=0001, T1, Sv1=0070 (room temp)<br />
<br />
C2=0001, T2, Sv2=1250<br />
<br />
Now Let me explain what T is. T1 is supposed to be the time (in minutes) we are telling the controller to get from Sv1 to Sv2.<br />
<br />
So our programming looks like this:<br />
<br />
C1=0001, T1=240, Sv1=0070 (room temp)<br />
<br />
C2=0001, T2=30, Sv2=1250<br />
<br />
C3=0001, T3= 60 , Sv3=1250<br />
<br />
.<br />
<br />
.<br />
<br />
.<br />
<br />
Note that I am rounding to the nearest half hour because kiln work isn't that fussy<br />
...until you get to Pate de Verre, which is not covered in this lesson.<br />
<br />
Once you have put in all steps, scroll up to END and hit SET. This enters your program. The controller will keep it, even if switched off.<br />
<br />
<br />
Once programmed, you can <br />
<br />
1) Make sure the Thermocouple (yellow plug) is plugged into the yellow socket (check polarity).<br />
<br />
2) Make sure the data signal (blue cat5e wire) is plugged into the Controller and the Relay Box.<br />
<br />
3) Make sure the Relay box is plugged into the wall and the circuit breaker is set to ON.<br />
<br />
4) Roll the cart OUT of the cage.<br />
<br />
5) Make sure the top of the kiln is plugged into the bottom.<br />
<br />
6) Make sure all 3 knobs are set to 10 (or to 11 if you are a Spinal Tap fan).<br />
<br />
7) Make sure the Kiln is plugged into the Relay Box.<br />
<br />
8) Turn on the Controller with the Green Switch.<br />
<br />
9) Hit the > key and you ???<br />
