Bartlett GENESIS SPARK Technical Manual

The Genesis Spark controllers regulate the temperatures in a kiln according to the program set by
the artist. It has two different programming modes, Cone Fire, Glass, PMC, Heat Treat, Custom and
Library. It is a single zone controller (one thermocouple input) with Safety output. This controller can
only use a Type K thermocouple.
The Genesis Spark requires a 24V center-tap transformer. It connects to quick connects, labeled
AC1, CENTER TAP, and AC2. The VA rating of the transformer is dependent on the electrical load of
the board and relays. The board requires approximately 80mA at 12V DC and a relay typically requires
approximately 140mA at 12V DC. Therefore, a three-relay system will require a transformer with a
minimum rating of 6VA (500mA X 12V DC = 6 VA). (Note all 3 relays would wire to the single output)
The Genesis Spark board has two 12V DC outputs. The output is given power by a safety
transistor. The safety transistor is capacitor coupled to the microprocessor so it only powers the output
transistors when the microprocessor is operating correctly. The output responds to thermocouple input.
The Output and Safety can drive a 500mA 12 V DC load max. The maximum combined output of all
outputs is 1 Amp. The safety output powers on at the beginning of a firing and off at the end of the firing.
It is used to drive a safety relay that sends line power to the switching relays on the output.
FACTORY PROTECTED - "HIDDEN MENU"
The "hidden" menu allows programming of options that are normally set at the factory. The
options are listed in the order they appear in the menu with a description. The "hidden" menu can be
entered by pressing "MENU", scroll down to "Factory Protected", and selecting "Factory Protected".
Then, type in the sequence 4, 4, 3, and the Factory Protected options will be displayed. Use the scroll bar
on the right to scroll through the options found below: Rotate Display, Max Program Temperature,
SSR Mode, Cycle Time, and Run Factory Diag.
Rotate Display
When set to on, the display will rotate 180 degrees. To rotate the screen, press "On" and then
press "Save".
Max Program Temperature
Enter the top temperature the kiln is rated for. Set the Max Program Temperature to the maximum
temperature rating for the kiln. Check the side of the kiln or the kiln's manual for its temperature rating.
The max setting is 2400°F (1316°C).
SSR Mode
SSR Mode can be turned on when solid state relays are being used on the kiln. When SSR mode
is turned on, it cycles the relays at 500 millisecond intervals. This works the same with either 60hz or
50hz systems.
