STANDARD EQUIPMENT ON ALL GAS KILNS

Control System Standard manual control system used on most GEIL KILNS.

Control System Standard manual control system used on most GEIL Kilns.

DD-1 Digital Electronic ControllerThe DD-1 is a high limit, on-off, solid state electronic controller with a digital readout and digital set from 0 to 2500� F. When the controller is set at the "High Limit" position, it will automatically shut the kiln off at the set point temperature. The on-off position functions as a "soaking" controller, holding the temperature at the set point temperature, plus or minus 5�.

Heavy Duty Hinge An exclusive feature on all front loading GEIL Kilns, this hinge is fully greased to prevent rusting and reduce wear.

Burner System Natural draft, high velocity ceramic Venturi burners were specifically created and designed by GEIL Kiln Company for the GEIL Downdraft Design system and have proven to be quite efficient in all applications.

ALL GAS & ELECTRIC KILNS INCLUDE:

The ETL Certification All GEIL GAS KILNS conform to A.G.A. STANDARD 1-94 and certified to CSA STANDARD C22.2 NO.3.

All GEIL Electric kilns conform to UL STANDARD 1-94 and certified to CSA STANDARD C22.2 #221.

NOTE: All individual shelving not ordered with kiln carries a 10% packing charge. Silicon Carbide Shelving -- Quoted upon request.

The microprocessor controller is the main controller of the system, responsible for time, temperature and atmosphere of a kiln firing. It reads the temperature by means of a thermocouple mounted on the back wall protruding into the interior of the kiln. The microprocessor then processes the pre-programmed parameters (i.e.: ramp soak segments) and adjusts the output signal to the proportioning valve located on the valve train. Depending on the call for heat from the microprocessor, the proportioning valve will vary the amount of gas reaching the burners. The kiln is also equipped with an oxygen probe located just below the thermocouple. Reading the atmosphere of the kiln via the oxygen probe, the microprocessor sends a signal to the damper motor which then adjusts the damper automatically to control the atmosphere. By programming the microprocessor's parameters with time and temperature, the kiln can be fired by ramping to a set point within a particular time frame. This ramp time plus a soak time is one segment. The microprocessor contains four ramp soak segments making up what is called a firing profile. This profile is stored in the microprocessor's nonvolatile memory. The microprocessor contains two operating modes, AUTO and MANUAL. These pre-programmed firing profiles can be operated by the AUTO mode. The kiln can also be fired manually by the microprocessor controller.

Our auto-damper system is PC controlled using a windows based program that is very easy to operate and hook up. All the parameters from the controller are displayed on your computer screen, making it easier to update and change your firing profiles. The program takes about 5 megabytes of space on your hard disk. There are no major upgrades needed for you to install and connect the microprocessor program. The microprocessor program offers remote station firing capabilities.

UNDERSTANDING THE PYX MICROPROCESSOR The PYX controller is the main controller of the system, responsible for the time and temperature of a kiln firing. It reads the temperature by means of a thermocouple mounted on the back wall protruding into the interior of the kiln. The PYX reads the temperature via the thermocouple. It then processes the pre-programmed information (ie: ramp/ soak segments) and adjusts the output signal to the proportioning valve. Depending on the call for heat from the PYX, the proportioning valve will vary the amount of gas reaching the burners. The output signal is shown as a percent in the OUT1 parameter. Each parameter is explained in detail in the next section. By programming the PYX parameters with time and temperature, the kiln can be fired by ramping to a set point in a particular time. This ramp time plus a soak time is one segment. The PYX contains four ramp/soak segments making up what is called a firing profile. This profile is stored in the microprocessor's nonvolatile memory. The PYX contains two operating modes, AUTO and MANUAL. This pre-programmed profile is operated by the AUTO mode. The kiln can also be fired manually by the PYX controller. Manual firing can be used to perform a reduction.

The microprocessor controller is equipped with a high-limit alarm. The high-limit alarm will shut the kiln down once the kiln hits the high limit temperature. The damper is automatically closed to prevent any thermal shock. lf there is any disruption of gas or flame failure, the flame safety system will automatically shut the kiln down. Our auto-damper system is backed by an ETL Intertek (Canadian Standard Association) certification, meeting the required safety standards for gas appliances.
