Genesis Control Instructions

Operation Manual

Genesis 2.0 & Genesis Mini - Model LT1120

INTRODUCTION

This manual covers the operation of the Genesis 2.0 & Genesis Mini LT1120 kiln controllers. The Genesis is a versatile touchscreen controller that regulates the temperature in your kiln so you can fire various products like ceramics, glass, jewelry, and more. The Genesis has preset ceramic programs with cone fire programming, preset glass firing profiles, 30 custom programs, Wi-Fi capabilities for software updating, built-in diagnostics, and maintenance logging, among other new features.

PRECAUTIONS

The controller is used to control temperature; it is not a safety device.
Do not operate the controller in temperatures above 160 ̊ F.
Always supervise your kiln during a firing.
The controller contains electronic components which are sensitive to static electricity. Before handling the controller, dissipate any static charge you may have by touching metal or a screw on the controller panel, the electrical box, the kiln lid, or some other grounded object.
Always check the position of the thermocouple probe before starting a firing. The current temperature displayed on the controller is measured at the end of the thermocouple, which must protrude about 1” to 1-1/2” into the firing chamber. If necessary, seal the opening around the thermocouple with kaowool or similar material.
Always review the current program before firing to ensure the correct profile is programmed.
Ensure the kiln and the areas around the kiln are clear of combustible material. See hotkilns.com/cautions/clearances-flamable-surfaces

Quick Start

First Firing Of The Kiln

See https://www.youtube.com/video/TMpWNf1tGjY

The purpose of the first firing is to put a protective oxide layer on the elements and thermocouple. The first firing is done without ware in the kiln that might give off fumes that contaminate the elements. This first firing should have shelves and witness cones. The witness cones should be on the middle of the shelf nearest the center of the kiln. If your kiln is supplied with cones, the programmed cone number should match the cones provided, or you may use a cone of your own choice for the first firing. The example below is for a cone 04 firing, but if you use a cone other than 04, substitute that cone number in the programming.

Program the Controller

This example is for a Fast Glaze to cone 04 with no hold time at the end of the firing. The example below is for programming in Novice Mode.

Review the Results

A properly bent cone indicates that the kiln is functioning properly and accurately. The tip of the cone will be level with the top of the cone’s base when fired properly. The diagram below will give you an idea of a properly fired, under fired, and over fired cone. Some variations from a proper bend is expected and can be compensated for with the cone offset adjustment for each particular cone number based on test firings.

Figure 7: Samples of under fired, properly fired, and over fired cones.

Ceramics Programming (Bisc Or Glaze)

Programming in Novice mode is the easiest method to program the controller to fire ceramics. Programming consists of choosing a cone number, firing speed, and a preheat time. The firing speed is chosen by the type of firing and thickness of the clay used. All 4 speeds below will calculate the firing rate at the end of a firing and adjust the final temperature for correct heat-work.

Step	Display Shows	Key Press	What This Selection Means
1	Home Screen	Load	You’re ready to load a different program into the controller memory.
2	What are you firing?	Ceramics	Choose from Ceramics, Glass, and Other. Choose Ceramics for a bisc or glaze firing.
3	Cone Number XX Temperature XXXX	Next	Use the scroll bar to choose the desired cone number for the firing. Remember, cone numbers starting with a 0 are a lower temperature than cone numbers not starting with a 0. For example, don’t mistake a cone 6 for a cone 06!
4	What Speed?		Choose the firing speed either Fast, Medium, MedSlo, or Slow.
		Fast	Fast is the fastest firing speed and is used for glaze firings on thin ware, china paint firings, and decal firings. Firing times range from 4 to 5 hours.
		Or Medium	Medium is used for firing glaze on thicker ware or for bisque firing very thin ware. Typical firing time is 6-8 hours depending on the cone number.
		Or MedSlo	MedSlo is used to bisque medium pieces or thinner ware that requires less time for water smoking and carbon burn-out. Typical firing time is 9-11 hours, depending on cone number.
		Or Slow	Slow is used to bisc thicker, hand thrown ware. The slow speed gives extra time for release of water and carbon burn-out. Typical firing times range from 13-17 hours depending on the cone number. Hand built pieces may need a preheat stage.
5	Preheat Time?		Choose the preheat time, either None, 4 Hr, 8 Hr, or 12 Hr.
		None	No preheat time is needed when the pieces are a thin, bone dry bisc or glaze.

Figure 9: Custom programming sample.

Notes For Custom Programming:

A firing will start in the earliest segment with a temperature greater than the current kiln temperature. If the current kiln temperature exceeds all segment temperatures, the controller will go directly to complete.
To ramp up or down at the maximum rate, enter a rate of 9999.
To program a down ramp, enter the rate/hour then a temperature below the previous segment’s temperature.
It is best to write out the firing profile that you plan to program before you begin programming. A blank form for writing your firing programs can be found in Appendix D: Blank Firing Program. Photo-copy as needed.

Calculating Ramp Rates for Custom Firing

If you want to go from room temperature to 750°F in 3 hours, use this method to calculate the ramp rate. Take the temperature that you want to go to (750°F) minus the starting temperature (70°F – approximate room temperature) to get the number of degrees you want to increase in 3 hours (750 – 70 = 680). Divide this number by the time you want to get to 750 to give you the ramp rate (680°F ÷ 3 hrs = 227°F/hr). If you want to add another segment to go from 750°F to 1000°F in 4 hours, the same procedure is used. Take the end temperature minus the starting temperature (1000 – 750 = 250) and divide this number by the number of hours to reach 1000°F (250°F ÷ 4 hrs = 63°F/hr).

Figure 10: During a Custom Firing, you can enter the desired temperature or press CONE. Choose the desired Cone Number and the controller will enter the corresponding temperature.

Custom Ceramics Program

Writing your own ceramics program combines the versatility of the Custom program and the heat-work calculation of a ceramics firing. It is a great way to get custom heating and cooling rates and still have the controller do the heat-work calculation to get the correct cone bend regardless of firing rate. The steps to write your own cone fire are the same as entering a Custom program except when programming the top temperatures, press the “CONE” button, scroll until the desired cone number is displayed, and press “SAVE”. The selected cone’s top temperature will be displayed under Temp for that segment. The cone temperature can be entered into any segment so you can also have cool down segments in the program. For blank tables to write down your custom programs, see Appendix D.

Start A Firing

Press “Start” to open the Start Firing Screen. There are 3 options as to how you’d like to begin the firing. To start the kiln immediately, press “1-Start Now”, enter the start code (Default = 1), and press “Start”. To program the kiln to start in a set amount of time press “2-Start Later”, enter the start code, press “Start”, enter a delay start time of up to 4 hours, and press “SAVE”. CAUTION: Make sure the kiln area will stay clear and safe throughout the delay time and firing time. To arm the controller for a remote start via the KISS program, press “3-Remote Start”, enter the start code, and press “Start”. The controller will now read “REMOTE” at the top. This means the area around the kiln is clear, it’s loaded, and it can be fired at any time from the KISS program.

Operation of the Controller During A Firing

The Genesis controller eliminates much of the “babysitting” that is required with a manual kiln. To ensure the most consistent results from one firing to the next, you should understand how the controller operates and monitor the firing to ensure proper operation. The following diagram and flow chart show the basic components of a kiln’s control system.

Figure 11: Kiln Operation

Figure 12: Shows a flow chart of the control algorithm in its simplest form. Like your home thermostat.

The diagram and flow chart show that the kiln control system, in its simplest form, works like your thermostat at home – when the temperature is too cool the heater comes on; when the temperature is too hot the heater turns off. The major components of the control system are the Genesis controller, thermocouple temperature sensor, relay switch, power source, and heating elements. The controller is the brain of the operation; the controller adjusts the traveling set point according to your program, reads the temperature in the kiln, cycles the relay on or off and determines when to end the program.

The thermocouple (T/C) sensor is the first part to inspect when loading the kiln. The tip of the T/C should protrude approximately 1- 1/2” into the firing chamber. Next, “START” is pressed, the controller reads the kiln temperature and uses that temperature as a starting point for a traveling setpoint (also called the local set point). The displayed temperature is the temperature inside the kiln. You should then hear the relay(s) start cycling on and off to keep the temperature near the traveling set point. As the firing progresses the controller moves the traveling set-point according to the programmed firing rate. The displayed temperature should increase with the traveling set-point and the relay will be “on” longer. This sequence continues until the final temperature is reached and the controller turns off the kiln. The display reads “COMPLETE”.

Figure 13: Sample graph of program during a firing

Adjustments During a Firing

Once a firing has been started, the screen will change to the Firing Screen.
You can still view the program and make adjustments to the firing.

See https://www.youtube.com/video/LT6VAD7em_0

Stop

Press STOP at any point in the firing to immediately stop the firing. The controller will return to the Home Screen. To start the program again, simply restart the kiln. The controller will start in the segment with an up-ramp equal to the kilns current temperature. If the kiln does not restart in the segment it was stopped in, press the Adjust button and skip to the desired segment.

View (Applies to Novice Mode)

View the setting for the firing. For a ceramic firing, the preheat time, cone #, speed, and hold time will be displayed. Press the “Graph” button to view the firing as a graph. This includes time, temperature, and segments. To see each individual segment, press the “TABLE” button. Changes or adjustments to the firing can’t be made here once the firing has started. To make adjustments, press the Adjust button.

Graphing Key:

Item On Graph	Meaning
Orange Vertical Line W/ Number	Segment of the firing
Green Vertical Line W/ Time	Current firing time. Represents where the firing is currently, compared to the graph
Gray Vertical Line W/ Time Below	Time at various points throughout the firing
Yellow Graphing Line	Projected path of the firing
Green Graphing Line	Firing’s actual path
Red Graphing Line	Firing’s supposed path (Shown only when actual path and supposed path are not the same)
Horizontal Gray Line W/ Temperature	Kiln Temperature

Edit (Applies to when Novice Mode is Off)

“Edit-on-the-fly”. Pressing the Edit key while firing a custom program will present the table view. Gray segments have already been fired and cannot be changed. All edit features listed on page 12 are available to segments that have not been completed.

Adjust

Press Adjust to make adjustments to the firing while a firing is in progress. Pressing “Add Time” during a hold segment of the firing will add 5 minutes to the hold. It has no effect if the firing is not in a hold when pressed. Pressing “Add Temperature” during a hold segment will increase the hold temperature by 5°F. It has no effect if the firing is not in a hold when pressed. Pressing “Skip Step” will skip the current segment and move to the next in the firing. This feature is used when enough heat work has been done at the current segment and you want to immediately go to the next ramp rate. Pressing “Alarm Temp” allows you to adjust the alarm temperature for the firing. A temperature of 9999 shuts the alarm off.

The firing menu allows for viewing of statistics and mid-firing diagnostics. By pressing “Diagnostics”, the controller runs a manual diagnostics test during the firing. Pressing “TC Offsets” allows the user to change the temperature offsets for each thermocouple. Minimum: -99°F Maximum: 99°F.

End of Firing – COMPLETE

When the firing is complete, an alarm will sound and the controller will display COMPLETE with the current temperature and firing time. To return to IDLE, press “Clear”. You may open the kiln when the temperature has cooled to 150°F.

Care of Thermocouples

The small metal rods protruding into the firing chamber are the temperature sensors, or thermocouples. Do not let shelves, posts, or ware touch the thermocouples; this could affect the temperature reading. The number of thermocouples will depend on the model of kiln.

The protection tubes covering the thermocouples will help prevent some damage, but make sure to avoid bumping them when loading and unloading as this can still harm the thermocouples or bump them out of the firing chamber.

The thermocouples should protrude into the firing chamber between 1 1/8" - 1 1/2".

Avoid firing clay with high sulfur content. The sulfur erodes the thermocouples making them brittle and easy to break.

Main Menu

By pressing the Menu button on the Home Screen, you’ll be taken to the Menu Screen. The Menu Screen is a list of various options from checking your last firing status, diagnostics, offsets, and controller configuration among other things. To navigate through the Menu options, slide the green scroll bar on the right side of the screen up or down for more options. For more information on each option in the Menu, see the descriptions below:

Output 4 Options – (Usually set as a factory option)

Output 4 has 3 modes for running vent fans (Options A, B, & C), one mode that uses Output 4 to indicate the alarm has triggered (Alarm), and one mode for running elements in the lid or floor of the kiln (Percent).

See https://www.youtube.com/video/nfyz8djCn74

Option A
Used to control a vent. Output 4 can be programmed to be on or off during each segment of a Custom program.During a Ceramic or Glass program, output 4 come on at the beginning of the firing and turns off after the kiln has cooled to 150°F.
Option B
Used to control a vent. Output 4 can be programmed to be on or off during each segment of a Custom program. Output 4 comes on at the beginning of a Ceramic or Glass program, off at 1450°F, back on after the firing is complete and the kiln has cooled to 1000°F and finally off again when the temperature is below 150°F.
Option C
Used to control a vent, an alarm, or other atmospheric control. Output 4 can be programmed to be on or off during each segment of a Custom program. Output 4 is off during Ceramic and Glass programs.
Alarm
When this option is selected, Output 4 comes on when the alarm is triggered or an error code is encountered.
Percent
Output 4 can be programmed to be on for a percent of the time Output 3 is on. This option is used when Output 4 controls floor or lid elements. To ensure Output 4 stays off at all times, use this option and set the percentage to zero.

Factory Configuration - "Hidden Menu"

Factory Configuration, or the "Hidden Menu", is used by L&L Kilns to set kiln specific parameters for the controller such as thermocouple type, top temperature, and board temperature.

Contact service@hotkilns.com before making any changes that might damage the kiln.

To access the Hidden Menu, select "Factory Config", enter the code number 443 and press "Save".

TC Type

Change the thermocouple type used with the controller from Type K, Type S, or Type R. To change thermocouple type in Factory Configuration, select the thermocouple type being used with the controller and press “Save”. When changing from a Type K to a Type S or Type R, you must change the software setting as well as placing a jumper on the circuit board. To change from a Type S or Type R to a Type K requires changing the software setting and removing a jumper from the circuit board.

WARNING: Using a Type S thermocouple and a controller set for Type K will cause serious over-fire. Using a Type K thermocouple and a controller set for Type S will cause an under-fire. Type S thermocouples must use Type S extension wire. Type K thermocouples must use Type K extension wire. If changing thermocouple type be sure to change the extension wire. Make sure the software and jumper settings match the type of thermocouple and extension wire you are using.

See https://www.youtube.com/video/uU4QlWWve2k

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).

Max Board Temperature

Set the maximum temperature the circuit board can reach. Valid temperature are 0 - 250°F. If the board reached a temperature higher than 250°F, it can cause serious damage to the circuit board

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.

Cycle Time

Sets the output cycle time. The cycle time is the length of time between an output coming on two consecutive times. If the cycle time is set for 14 seconds the output will come on every 14 seconds as needed. Cycle time can be set from 10 seconds to 60 seconds. To change the cycle time in the Factory Configuration Menu, press “5-Cycle Time”, type in the new time, and press “SAVE”.

Current Sensor Rating

The Current Sensor Rating is used to set the number of Amps that will generate a 5V output from a current sensor. Factory default is 50 Amps.

Run Factory Diag.

This is used by L&L Kilns when manufacturing. The factory diagnostics can be used for comparison when future diagnostics tests are ran. To view the amperages and voltages from the Factory Diagnostics test, press the “MENU” button, “1-Data Menu”, then “3-Factory Diagnostic” to view the results.

Rotate Display

When set to on, the display will rotate 180 degrees. To rotate the screen, press “On” and then press “Save”.

Output Config.

This setting should always be set on Standard, unless prior approval from L&L Kilns.

Mini Version

Use to switch screen formatting from larger Genesis screen to the smaller Genesis Mini screen. This setting should remain set to off for the 2.0 version.

Lid Switch

The Genesis 2.0 has connections for a lid switch. When a lid is connected and the lid switch setting is set to on, the controller will shut power off to the elements, sound an alarm, and give a LID OPEN message when the lid is opened during a firing. When a lid is connected and this is set to off, the controller will continue to fire as scheduled, even when the lid is opened.

Output 3 Alarm

The Genesis 2.0, when in single zone mode and Output 3 Alarm is enabled, output 3 will turn on and off with the alarm. It is used by some to run a louder alarm.

Appendix A: Error Codes

If you get an error code, it is important to note the error letter or number. It will help you in diagnosing any problem with the kiln. When an error code is displayed, it will give a short description of the error. Press “Clear” to clear an error code.

List of error codes:

NOTE: THESE ERRORS WILL ONLY BE DETECTED IF THE ERROR CODES ARE TURNED ON:

Error Code	Description	Possible Causes
ERROR 1	Kiln temperature increasing slower than 12o F per hour when ramping up	This is a kiln heating problem, not a controller problem. Do the Full Power Test to check elements and relays Low or dropping voltage to the kiln could also be the cause. A thermocouple reading incorrectly or improperly placed may also be the cause.
ERROR 2	Kiln temperature 50o F above hold temperature	A relay latched in the “on” position may cause this error. Another possible cause is if the kiln lid is opened for rapid cooling, then closed, such as for glass firings.
ERROR 3	Kiln temperature 50o F below hold temperature	Relay failure.
ERROR 4	Kiln temperature 50o F above previous hold when ramping down	Same causes as for E-2.
ERROR 5	Kiln temperature 50o F below traveling set point when ramping down	Relay failure.
ERROR D	Kiln temperature 50o F above traveling set point	Stuck relay or stuck output. If using zone control, then the outputs or t/c’s may be in the wrong zones.

NOTE: THE ERROR CODE SETTING DOES NOT AFFECT THESE ERRORS:

Error Code	Description	Possible Causes
ERROR 0	Software error	Check the selected program and reprogram, if necessary. If error persists or program does not hold in memory, controller may need to be returned to factory for service.
ERROR 6	Problem with thermocouple leads	This generally indicates the thermocouple is connected incorrectly, possibly reversed. Ensure the thermocouple extension wires are connected correctly to the controller and at all connection blocks back to the thermocouple.
ERROR 8	In cone fire mode, temperature decreasing in last segment	If the kiln has a kiln-sitter, it may have turned the kiln off before the controller did. Other possible causes are broken element or relay failure.
ERROR 9	Software thermocouple selection does not match the hardware thermocouple jumper selection	The jumper on the circuit board and the setting for thermocouple TYPE in the software do not match.
E--	Power loss during EEprom write	Turn the controller off and back on. Recheck the selected program and reprogram, if necessary.
ERROR A	Invalid program variable	Reprogram all segments of the program being fired. If error persists, controller may need to be returned to factory for service.
ERROR bd	Board temperature too high	The control box temperature may be too hot or the limit temperature may need to be reset. If the room temperature is very hot, aiming a fan at the control box may decrease the temperature.
ERROR E	Hardware error	Controller will need to be returned to the factory for service.
ERROR R	Microprocessor memory does not match program storage memory (EEprom)	Reprogram and try to fire again. If error persists, controller may need to be returned to factory for service.
ERRP	ERRP will display. To clear the display, press “Clear”. The firing in progress will continue.	Power outage; kiln is still firing.
Thermocouple FAIL	Thermocouple FAIL indicates one or more t/c’s have failed. If more than one thermocouple is connected, the controller will indicate which thermocouple has failed.	Check the board temperature under Diagnostics under Menu. If the board temperature is approximately room temperature, then the t/c is defective. If the board temperature shows a high temperature the circuit board is defective.
PF	Power failure. Firing has stopped.	Power was lost during a firing and the kiln temperature was below 140o F or the kiln temperature dropped more than 250 degrees during the power outage.

Full Power Test

The full power test is used to check the relays and elements of the kiln. To set the controller for a full power test, simply load the User12 program and turn the alarm to 9999. With the kiln empty and the lid open, start the firing Visually inspect the elements after the kiln has fired for 20 – 25 minutes. Observe each element from where it comes into the kiln all the way around to see that it is equally bright throughout. The following observations are possible:

One section of the kiln is dark and not coming on.
This could indicates a defective relay since there is usually one relay per section.

One element is not glowing at all.
This indicates a broken or bad element.

There are darker (Cool) spots along the elements.
This indicates worn elements.

The top and bottom elements appear brighter.
This is normal for many kilns that have hotter elements in the top and bottom.

After you’ve made your observations, turn off the kiln. Contact service@hotkilns.com for kiln replacement parts (relays and elements). If there is an issue with your controller, please contact us.

Appendix E: Common Questions And Situations

Q. How do I clear an error message?
A. To stop the sounding alarm, press anywhere on the screen. Then to clear the message, press “Clear” and the controller will return to the IDLE screen.

Q. What is a segment?
A. A segment is the basic building block of a program. Each segment consists of a ramp rate in degrees per hour, a temperature you want to achieve, and whether you want to hold there or not. For example, a program for drying ware going at 60°F/hour to 200°F and holding for 2 hours would be a one segment firing, the ramp is 60, the temperature is 200, and the hold is 2.00.

Q. Do I need to use witness cones for each firing?
A. After checking your kiln with witness cones for the first few firings, if you are satisfied with the results you are getting and how even the kiln is from top to bottom, then you do not need to use cones in each firing. It is a good practice to periodically place witness cones in the kiln to check for proper firing. If you suspect a problem or your results have changed, then it is a good idea to check the operation of the kiln with witness cones.

Q. Who do I contact for parts for my kiln?
A. For replacement parts for your kiln (relays, elements, etc.), contact L&L Kilns Mfg. (hotkilns.com/parts) or your local distributer.

Appendix F: Zone Control

Your kiln must have multiple thermocouples and be wired for multiple zones to take advantage of these features.

1. Features and Enhancements

3 separately controlled zones (3 T/C inputs, 3 outputs)
Adjustable offsets for each thermocouple (T/C)
Continues to fire with 1 or 2 failed thermocouples (T/C’s)
Slows ramping when any zone lags the set-point
Reset function which zeros the TC offsets and turns the errors on

2. General Description

The Genesis advanced 3-zone control system is programmed the same as the single zone control but it ensures an even firing from the top to the bottom of the kiln. A 3-zone control has 3 temperature sensor inputs (thermocouples) and 3 independent outputs so the kiln can have 3 separately controlled sections (zones). The controller senses the temperature in each section of the kiln, compares the temperature to the desired temperature (traveling set-point) and adjusts the power going to each section separately giving each just the right amount of power to keep the temperature at the correct setting. The single zone controller only measures the temperature at the center of the kiln and gives all sections the same amount of power.

3. Automatic Lag Function

Lag refers to when the temperature of a kiln’s section “lags” behind the traveling set point because the programmed ramp rate is faster than the kiln’s temperature can rise. The Genesis will slow the ramp rate when a section of the kiln lags. The ramp rate determines the amount of “lagging” that is allowed before the firing rate is slowed. Fast ramp rates (>500 °F/hr) will allow the greatest temperature difference between sections. Slow ramp rates (<70 °F/hr) will have the smallest temperature differences between sections. Therefore, when the controller is programmed to go fast it will sacrifice evenness to obtain speed. Likewise, when the controller is programmed to go slow, the controller will maintain tighter control. The controller will try to balance speed and tight control when a medium speed is programmed.

4. Thermocouple Offsets

Normal variation in thermocouples can cause a section to fire too hot or too cold. The zone control has an offset feature to adjust the reading of each thermocouple to compensate for any error. For example, if shelf cones indicate that the bottom section is under firing, it means that the controller thinks the bottom section actually reached the ending temperature when it really was below the ending temperature. To correct this problem, a negative thermocouple offset is required. This offset will be subtracted from the actual reading and will lower the temperature reading in that section. A negative offset will cause a section to fire to a higher temperature increasing the heat-work for that section. A positive offset will cause a section to fire to a lower temperature decreasing the heat-work for that section. To return all TC offsets to zero, press “Menu”, scroll down and press “5-Restore Presets”, press “2-Reset TC Offsets”, and press “RESTORE”.

5. Three Thermocouples

Besides better measuring of the temperature, the zone control also offers security through its three thermocouples. With a single zone controller, a firing will be stopped if the thermocouple fails. The zone control with 3 T/C’s will continue to fire if one or two of its thermocouples fail during a firing. If the top or bottom thermocouple fails, that section will be controlled by the top T/C. If the controller is at IDLE and a T/C fails, “Error Thermocouple Failed” will appear on the screen.

When using three thermocouples, thermocouple 2’s temperature is displayed under current temperature. The temperature of each zone can be viewed during the firing. To view the other thermocouple temperatures, press the screen where the current temperature is displayed. The temperatures for all three T/Cs, percentage of power to the elements, and the current Set Point will appear.

6. Programming Number of Thermocouples

Selecting the number of thermocouples is set up in the regular Menu. This allows one controller board to be used for single or multi-zone kilns (Genesis 2.0 Only). To program the number of thermocouples, press “MENU”, scroll down to “4-Configuration”, and select it. Scroll down to “5- Number of Zones” and select it. The Genesis Mini only has the option to be set to 1 zone. When using the Genesis, type in the desired number of zones (1, 2, or 3) and press “SAVE”. When programmed as a single zone board, TC1, TC2, and TC3 will all read the same temperature on the Home Screen. When in multi-zone mode, they will read the temperature for the corresponding thermocouple

SINGLE ZONE (NUMBER OF THERMOCOUPLES IS ONE)
On the Genesis 2.0, the input T/C 2 is used when it is programmed for single zone control. All three outputs work in unison so there are two alternatives for connecting the output. All relays can be connected to output 2 or one relay could be connected to each output. The first method allows direct replacement of the current single zone controller without changing wiring. The second method would allow an easy upgrade to a multi-zone kiln in the future by just adding thermocouples and reprogramming the number of T/C’s. The second method also allows for better use of the diagnostic routines. On the Genesis Mini LT1120, there is only one thermocouple input on the controller

3-ZONE (NUMBER OF THERMOCOUPLES IS THREE) – Genesis 2.0 Only**
T/C 1 is the top thermocouple, T/C 2 is the middle, and T/C3 is the bottom. Likewise, output 1 drives the top relay, output 2 the middle, and output 3 the bottom. For taller kilns, output 2 can control several middle sections.

2-ZONE (NUMBER OF THERMOCOUPLES IS TWO) - Genesis 2.0 Only**
When two thermocouples are selected, use inputs T/C1 and T/C2 and outputs 1 and 2.

Appendix G: Technical Information

Power Supply

The Genesis 2.0 board requires a 24V center-tap transformer. It connects to the board’s bottom three 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 8 0mA 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).

The Genesis Mini LT1120 board requires a 24V center-tap transformer. It connects to the board’s 5 pin friction lock connector or to the left three quick connects, labeled AC1, CENTER TAP, and AC2 if the adapter board is installed. 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.

Outputs

The Genesis 2.0 board has five 12V DC outputs. Four outputs are given power by a safety transistor, outputs 1, 2, 3, and safety. The safety transistor is capacitor coupled to the microprocessor so it only powers the output transistors when the microprocessor is operating correctly. Outputs 1, 2, and 3 respond to their respective thermocouple inputs. All outputs are capable of driving a 500mA 12 V DC load. Output 4 is an extra output that can be programmed to run a fan, alarm, or extra kiln section. 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 outputs 1, 2, and 3. When using the optional current sensor, wiring one section to each output will give an Amp reading per section for better diagnostics. See Configuration in the controllers Menu for details on the output 4 options.

Full Diagnostic Routine

The full diagnostic routine checks all the output voltages, the amperage or current draw of each section of the kiln, as well as the no load and full load kiln voltages. The amperage or current draw is used to measure the current draw of each section of the kiln. The diagnostic routines can only control each section separately if the outputs are wired for zone control. When checking the output voltages, the controller will turn on each section, starting with the top, for a few seconds. This allows checking to see if all elements are heating. The kiln voltages during load and without load are also measured. This helps to diagnose firing problems when the kiln is not able to reach a programmed temperature. First, it will read the voltages with the elements off, then the elements will come on momentarily and read the voltages again. To run a full diagnostics routine, follow these steps:

Press the “MENU” button.
Press the “2-Diagnostics” button.
Press the “2-Run Manual Diag.” button and the controller will begin the diagnostics routine.
The controller will flash to the home screen and “CHK ALL” will be displayed across the firing banner. When the test is complete, it will return to IDLE.
To view the results, press the “MENU” button.
Press the “1-Data Menu” button.
Scroll down to “5-Last Manual Diag.” and select it.
Use the scroll bar to observe the results. You can use the Factory Diagnostics for comparison with your results. When you are finished press the “BACK” button.
To return to the Home Screen, press “HOME”.

Voltage Calibration

To display voltage using the Genesis controller, a calibration must be done. Before calibration, make sure the relays and elements are connected. To run the voltage calibration follow these steps:

Press the “MENU” button
Scroll down to the “6-Factory Config” button and select it.
Type in the sequence “4”, “4”, “0”, and press the “SAVE” button.
The screen will read, “Are you sure you want to calibrate the voltages?” If you are ready, press the “START” button to begin or “CANCEL” to return to the menu.
After the “START” button has been pushed you’ll be asked to enter the no load voltage. The No Load voltage will need to be measured and entered into the controller. Min: 0 Max: 999.
Once you’ve typed in the No Load voltage, press the “SAVE” button and the screen will change to the Full Load voltage screen, and the power to the elements will be turned on.
Measure the Full Load voltage and enter the value into the controller and press the “SAVE” button.
The screen will read Voltage calibration is complete. Press the “HOME” button to return to the home screen.
