Controller Description
The GlassMaster 33 Controller
The GlassMaster 33 Controller was designed specifically for the needs of the Borosilicate
Flameworker. It is simple to operate yet has the most innovative programming features on the
market. You can use the factory stored programs for Heat up, Annealing. Striking and Repairing
or design your own using the Ramp and Hold programming feature.
Certain features are accessible only when the kiln is in certain stages of programming or opera-
tion. We call these stages MODES. To find out what features are available in each mode consult
the Program Modes Section of the manual.
Key Function
The COE 33 Controller has 4 buttons: UP Arrow, Down Arrow,
GO, and STOP. The arrow keys are used access menus, toggle
between menu options, and adjust temperature, rate and hold
values. When using the arrow keys to adjust values it is helpful
to know that the longer you hold the key down, the faster it will
scroll. If you overshoot your value just use the other arrow to
adjust back to it.
The GO key is used for selecting values and starting and advancing firing programs. The STOP
key is used only to STOP a program.
The Display
The display allows for 4 character prompts to be displayed utilizing 7 segments for each char-
acter. Sometimes it is necessary for us to be creative on the messages and characters we use. A
complete list of display descriptions is available in the Display Message portion of this manual.
Basic Operation
To Heat Up the Kiln
Press
GO
- The kiln will begin climbing in temperature as fast as it can go. The kiln will flash
“HtUP” (heat up) alternately with the rising temperature until it reaches 1100 F. When it reaches
temperature it will flash “AtSP” (at setpoint) alternately with the amount of time it is at setpoint.
Whenever you open the door the temperature will naturally drop. If the temperature drops
more than 8 degrees below set point, the timer will reset itself when it reaches the setpoint
temperature. This is to make sure you know the true amount of time your kiln is at the setpoint
temperature.
When You Are Finished Working
Press
GO -
The display will flash “no Str”(No Strike). Press
GO
again - The display will flash
“Stnd” alternately with “Annl” (Standard Anneal). Press
GO
again - The kiln will cool using the
Standard Annealing program and shut off when it reaches 150 F. It will flash CPLt, the current
temperature, and the total firing time. To return to IdLE, press STOP. (Go to the “Programs” sec-
tion of the manual to see the Standard annealing program values)
