Honeywell UDC2000 Controller Details

The Honeywell UDC2000 Digital Controller is designed to offer precise control over furnace and kiln operations, making complex firing schedules manageable. While initially requiring some study, its interface aims for ease of use comparable to a digital watch, unlocking significant power and convenience for various applications. It comes with a robust two-year warranty, including immediate technical assistance.

Safety is paramount when operating equipment with the UDC2000. Users are reminded to never touch hot surfaces, keep children away, and ensure proper installation on a stand with at least 12 inches clearance from combustible materials. It's crucial not to open a hot lid without protective gear and to always fire in a well-ventilated area.

For P 2000 portable units, correct thermocouple installation is vital to prevent overfiring. This involves choosing a suitable 1/2-inch vent hole, bending the thermocouple to extend 1-1.5 inches into the chamber, and securing it with a hold-down bracket. All kiln switches should be set to ON or High when using the controller.

The controller utilizes distinct segments for firing: Ramps, which are stages of temperature change (increase or decrease), and Soaks, where the temperature is held steady for a specified duration. These segments form the building blocks of programmed firings.

The UDC2000 offers three primary firing methods. The Single Set Point mode maintains a constant temperature indefinitely, serving as the default when no program is active. For more complex needs, the SPRAMP program provides a single-ramp firing, allowing users to define a target temperature and the time to reach it.

The most versatile method is the SPPROG, a 12-segment program incorporating six ramps and six soaks. This method allows for intricate, multi-stage firing schedules, which can be either factory-preset or entirely user-defined. This flexibility makes it suitable for diverse industrial and artistic applications.

Understanding the display messages is key. During firing, the lower display cycles through operational messages like the current segment and time left (e.g., 1 1.29 for SPPROG), total program time (RP 1.20M for SPRAMP), heating element output percentage (OT 100.0), the active set point (SP 502), and temperature deviation (DE-420).

Key operation involves SET UP for accessing adjusting modes, FUNC for function messages within those modes, and arrow keys for value changes. The DISP key cycles through operational messages and exits set-up displays. RUN/HOLD starts or pauses a program, but critically, it *does not* turn off the furnace; only the main on/off switch does.

The AUTO TUNE feature is a self-optimization process where the controller runs a trial to learn the furnace's heating properties, though it's rarely needed for factory-calibrated units. A RESET key allows users to cancel adjustments made with arrow keys before exiting a function message.

Specialized programming includes Delay Fire, which schedules a program to begin at a later time. This requires careful attention, especially for processes like wax elimination, where wax must be removed before temperatures exceed 350°F to prevent furnace damage. Users must always be present at the end of firing.

The controller also supports storing multiple firing schedules within the SPPROG program by utilizing different segment ranges. If a power failure occurs, the controller will automatically exit any active firing program and revert to the normal temperature display, running at the previously set Single Set Point.

Troubleshooting guidance addresses common issues. A KEYERR when pressing RUN/HOLD indicates that both SPRAMP and SPPROG firing schedules are disabled. Fluctuating temperature readings, often caused by radio-frequency noise, can be resolved by adjusting the FILTH 1 setting in the INPUT 1 Set-Up Mode.

Frequently Asked Questions (FAQs)

Can't find the answer you need? Here are some frequently asked questions about the Honeywell UDC2000 Digital Controller, and we answer them below.

What is the UDC 2000 controller's warranty period and technical support number?

The Honeywell UDC2000 Digital Controller comes with a two-year warranty. For immediate technical assistance, you can call 1-800-423-9883.

How do I remove the controller from my kiln if I need to send it for service?

To remove the controller, first loosen the screw on its face. Then, gently pull the controller straight out. When reinstalling, ensure it slides under the guide clip at the bottom and is pushed in all the way.

What are the basic safety rules for operating an electric kiln with the UDC 2000 controller?

Always place the kiln on a stand, maintain at least 12 inches clearance from walls/combustible surfaces, and operate in a well-ventilated area. Do not touch hot sides, keep unsupervised children away, and never open the lid while hot without appropriate protective gear. Disconnect the kiln before servicing and never leave it unattended while firing. Always turn the on/off switch to OFF after firing.

What is the difference between a 'Ramp' and a 'Soak' segment in a firing program?

A 'Ramp' is a stage where the furnace temperature is actively changed, either raised or lowered. A 'Soak' is a stage where the temperature is held steady for a specific length of time. Programs are built from a combination of these segments.

How do the RUN/HOLD key and the main on/off switch differ in function?

The `RUN/HOLD` key starts or pauses a programmed firing. When paused (HOLD), the furnace maintains its current temperature. However, it does *not* turn off the furnace's elements. To completely shut off power to the elements, you must use the physical on/off switch for the furnace.

What does 'Single Set Point' firing mean?

Single Set Point is the default mode when no firing program (SPPROG or SPRAMP) is active or after a program completes. In this mode, the controller will indefinitely maintain the furnace at a single, user-defined temperature. You can set it to room temperature to effectively keep the elements shut off.

How can I tell if there was a power failure during a firing program?

If there is a power failure while a program is running, the controller will exit the program and return to the normal temperature display (where the bottom display is blank). If you return to the furnace and see the normal temperature display, it indicates either a power failure occurred or the firing program completed.

What is Auto-Tune and when should I use it?

Auto-Tune is a test program that fine-tunes the controller's firing cycles by learning your specific furnace's heating properties. While it optimizes efficiency, it's rarely needed for controllers pre-configured at the factory. You would typically only run it if the controller's performance seems suboptimal or after significant changes to the furnace.

Why does my temperature read-out fluctuate, and how can I fix it?

Temperature read-out fluctuations are often caused by radio-frequency (RF) noise from other equipment (e.g., blowers, ultrasonic cleaners). To filter this noise, go to the INPUT 1 Set-Up Mode, find the `FILTH 1` Function Message, and use the arrow keys to enter a value like 15. If fluctuations persist, try a higher number; if stable, you might try lowering it slightly.

What does 'KEYERR' mean when I press RUN/HOLD?

A `KEYERR` message when pressing `RUN/HOLD` indicates that both firing schedules, the 12-segment SPPROG and the single-ramp SPRAMP, are currently closed (disabled). You need to enable one of these programs via the Set-Up Mode before you can start a firing.

Can I change a firing schedule while the furnace is actively firing?

No, the controller will not allow you to change the firing schedule while it is actively in the RUN state. To make changes, you must first press the `RUN/HOLD` key to put the furnace on HOLD. Changes made while on HOLD will apply to subsequent segments of the program, but the segment that was active when HOLD was engaged will fire with its original settings once resumed.

How do I program a delay fire, and what are the key warnings?

To program a delay, start your firing schedule with segment two. Set the temperature of segment two (SG2 SP) to the desired temperature during the delay (e.g., 0 for cold) and its soak time (SG 2 TI) for the delay duration. Important warnings: For wax elimination, you *must* remove the wax before the temperature exceeds 350°F. Always be present near the furnace at the end of any firing to ensure it shuts off correctly; overfire is not covered under warranty.
