Use with Kiln Wash. Remove any cardboard/plastic boxes from cage area during use.
Expect to change heating elements every 100-300 firings.

How to Plug in the Large Ceramic Kiln
1) The kiln you wish to use probably has this type of plug pattern in the end of the cord (Type 2).
The sockets on the wall have this type of pattern (Type 1)
So we have built an extension cord with a Built In Adapter. Socket for Type 2 leading to plug of Type 1.
Plug the kiln into this extension cord.
There are 2 places to plug in the Type 1 plug of the extension cord. The socket on the East wall of the Kiln Zone and the Switch Box on the fence on the South side of the zone. If you are using the KilnSitter, then plug the extension cord directly into the wall. If you are using the computer, plug the extension cord into the Switch Box.

How to Program the Kiln Controller
by Terry W.
Step 1) Turn ON controller with Green button. You should see the current temp in PV display.
Step 2) Push the SET button. You should see PASS in the PV display and 0000 in the SV display.
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.
You will see in books on glass, things called firing schedules. They look like this:
You read that as a set of instructions:
Ramp up the temperature from room temp to 1250F at a rate of 300F per hour.
THEN hold 1250F for 30 minutes.
THEN ramp from there to 1420F at a rate of 300F per hour.
THEN hold it for 30-60 minutes.
THEN ramp as fast as you can from there to 960F
THEN hold it for 90 minutes
THEN ramp at 50F/hr to 800F
SKIP holding it.
THEN ramp at 100F/hr to 600F
THEN turn it OFF and don't open the kiln until Room Temp (No Venting).
Your Kiln Controller needs to be programmed in a series of steps. Each steps has 3 attributes, C,T,Sv. So your list of instructions will look like
Let me define what each of those are.
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.
T is time, in minutes. More later.
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.
So from our example
C1=0001, T1, Sv1=0070 (room temp)
C2=0001, T2, Sv2=1250
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.
So our programming looks like this:
C1=0001, T1=240, Sv1=0070 (room temp)
C2=0001, T2=30, Sv2=1250
C3=0001, T3= 60 , Sv3=1250
Note that I am rounding to the nearest half hour because kiln work isn't that fussy ...until you get to Pate de Verre, which is not covered in this lesson.
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.
Once programmed, you can
1) Make sure the Thermocouple (yellow plug) is plugged into the yellow socket (check polarity).
2) Make sure the data signal (blue cat5e wire) is plugged into the Controller and the Relay Box.
3) Make sure the Relay box is plugged into the wall and the circuit breaker is set to ON.
4) Roll the cart OUT of the cage.
5) Make sure the top of the kiln is plugged into the bottom.
6) Make sure algnore formattingl 3 knobs are set to 10 (or to 11 if you are a Spinal Tap fan).
7) Make sure the Kiln is plugged into the Relay Box.
8) Turn on the Controller with the Green Switch.
9) Hit the > key.
1) Within 3 seconds of turning controller ON duty cycle goes to 100% and Sv reads LARGE value. Your T1 should be set to room temp or slightly below. If set to HIGH VALUE controller will immediately strive to take kiln UP to HIGH VALUE with 100% duty cycle.

Pyrometer gnore formatting Kiln Sitter (Not Installed)
July 1, 2013 - About 25 people have taken Kiln Training and are authorized to run the kiln solo. We have about 10 public casting molds of various shapes. These are on loan. There are about 3 dozen Glass Frit colors. These are owned by i3. We will start a cash box soon for their use. Each small jar costs about 8 dollars, so the costs will be prorated, probably like $2 per casting, including Boron Nitride use.
If your glass sticks in a mold, I now know new ways of recovery, please email me.
Remember we have Standardized on COE 96. Please contact me if you are going to use a non-standard COE.
Remember to change the kiln paper about once every 2-4 firings. Change it carefully because it gets powdery when used up.
We are petitioning the Membership in the July meeting to extend the fence by about 3 feet to accomodate Kiln 2.
With the addition, Kiln 2 is planned to be operational in Sept.
As of July 1, all items in the Kiln Zone which have not been ID'd and inventoried on this page as belonging to a member and on loan, will be ID'd and inventoried as belonging to i3. See me before July 15 if this presents any problems.
As of July 1, we should have all items in the KZ with either a Donation Log entry or a Loaner Form on file with the Board and me.
Damage lower wall and heating element, left side of kiln1. Reset brick for temporary fix. Should be good for July.
Need to get HEPA shopvac for removal of Kiln Paper.

-END JULY 2013-
August 1, 2013 This report will have all info that happened after July 1, but on or before Aug 1, 2013. I will accumulate information as the month goes and present the report in the first Member Meeting of August.
Kiln lower wall has some damage. Kiln good to go, but eventually will need maintenance. Thermocouple had problem. Replaced same.
Need to add time lapse camera to check if the kiln cycle is operating as expected over a day's worth of pictures.
-END AUGUST 2013-
Kiln Zone Expansion is 1/2 complete.
Waiting for parts shipment.
Expected completion date 9/30.
Kiln #1 is fully operational.
Kiln #2 will go ONLINE in October '13.
-END SEPT 2013-
