Universal Digital Controller
Overview
The UDC3000 Universal Digital Controller is Honeywell’s general purpose microprocessor-based, stand alone digital controller. It combines the highest degree of functionality and operating sim­plicity offered in a 1/4 DIN size. The bright dual displays with multi­language prompts make the operator interface easy to read, understand, and operate.
Programmed sequences of dis­plays assure quick and accurate entry of all configurable parame­ters. Simple keystrokes let you select input and range configura­tion, set the operating parameters that meet your process control needs now, and change them later to meet new ones.
Features
Dual Displays -
cent alphanumeric displays and indicators with dedicated PV display.
Deviation Bargraph -

Accutune II
truly plug and play tuning algorithm, which will, at the touch of a button or through a digital input, accurately identify and tune any process including those with deadtime and integrating processes. This speeds­up and simplifies startup plus allows retuning at any setpoint. Also included is the original Accutune SP Adaptive tuning that can automatically retune whenever a SP step change is implemented.
Fuzzy Logic -
uses fuzzy logic to suppress process variable overshoot due to SP changes or externally induced process disturbance. It operates independently from Accutune tuning. It does not change the PID constants, but temporarily modifies the internal controller response to suppress overshoot. This allows more aggressive tuning to co-exist with smooth PV response. It can be enabled or disabled depending on the application or the control criteria.

Optional Features continued
Auto/Manual Station Plus Backup Control - You can use a single
UDC3000 to act as both an Auto/Manual Station PLUS a back­up PID Controller, should the primary loop controller fail. Since the PID control is sometimes implemented in the PLC, this feature provides a very cost­effective way to insure the process does not have to shutdown or remain in manual mode if the PLC should fail. Switching from the Auto/Manual Station to the back-up control mode is accomplished using the Digital Input option.
Setpoint Ramp/Soak Programming - Enables you to
program and store 6 Ramp and 6 Soak segments for setpoint programming. Run or Hold of program is keyboard or remote switch selectable.
Physical Description
The controller is housed in a 5.8 inch deep, black metal case with a dark gray elastomer bezel, that can be panel mounted in a 1/4 DIN cutout, (see Figure 5.) The plug-in chassis allows easy access to the controller board and its various option boards. All power, input, and output wiring are connected to screw terminals on the rear panel, (see Fig 6.) Blue and tan elastomer bezels are optionally available.
Inputs
Each analog input is sampled 3 times a second, amplified and then converted to a digital signal which is isolated and passed to the microprocessor. The primary input can be one of various Thermocouple, Radiamatic, or Linear actuations, (see Table 1.) A second input provides a remote setpoint function and accepts a 4 to 20 mA or 1 to 5 Vdc range that can be characterized. All ranges are keyboard selectable. External cold junction compensation is provided. You can select upscale downscale, or failsafe sensor break protection. A configurable digital filter of 0 to 120 seconds for each Input provides input signal smoothing, if required.

Output Algorithms
The UDC3000 is available with one or more of the following output algorithms:
Time Proportional - provides On­Off or Time Proportional (Relay) output.
Current Proportional - supplies proportional direct current output for final control elements which require a 4-20 mA signal.
Position Proportional - positions a reversible motor with a feedback slidewire in proportion to the output of the control algorithm. Requires 2 output relays.
Time Proportional Duplex - depending on which control algorithm you select, this duplex output algorithm can provide On­Off Duplex, Time Proportional Duplex, or 3 Position Step Control. The time proportional duplex output provides independent PID tuning constants and two time proportional outputs; one for heat zone above the 50% output, and one for cool zone below 50% output.
Current Proportional Duplex - similar to current proportional but provides a second set of tuning parameters and a split range current output or a second current output via the Auxiliary output option, for the heat and cool zones.
Output Algorithms, cont
Current/Relay Duplex (Relay = Heat) - a variation of Duplex with
Current active for 0 to 50% output (Tuning Set 2) and Relay active 50 to 100% output (Tuning Set 1).
Current/Relay Duplex (Relay = Cool) - a variation of Duplex with
Current active for 50 to 100% output and Relay is active for 0 to 50% output.
“Universal” Output Model ­Flexibility of the Output Algorithms allows the Current Output Model with 2 Alarms (DC300K-E) to be also configured for time simplex, time duplex, or three position step control plus, of course, the original capability of current simplex and current/time duplex control. A Relay Output Model with Auxiliary Output can also be configured for these output algorithms.
Control Algorithms
Depending on the output algorithms specified, the controller can be configured for the following control algorithms:
On-Off
PID-A
PID-B
PD with Manual Reset
Three Position Step Control
The Three Position Step Control algorithm allows the control of a valve (or other actu­ator), with an electric motor driven by two controller output relays; one to move the motor upscale, the other downscale without a feedback slidewire linked to the motor shaft. Accutune does not apply to this algorithm. Features of this algorithm are:
1. The controller can use all three modes of control (PID) instead of PI only.
2. Three Position Step is an automatic backup mode to Position Proportional Control if the feedback slidewire signal should fail.
Configuration
You decide how the controller is to interact with the process by select­ing, through simple keystrokes, the functions you want.
Multi-language prompts guide the operator step-by-step through the configuration process assuring quick and accurate entry of all configurable parameters. There are no internal jumpers, all configu­ration is via the keyboard. Five languages are available via configuration; English, French, German, Spanish and Italian.
Control Modes
Manual or Automatic control with bumpless, balanceless transfer between modes is a standard feature. In the manual mode, the operator directly controls the controller output level. In the automatic mode, the controller will operate from a local setpoint, or a remote setpoint provided at the second input or via communications.
Alarms
Alarm output terminals are located at the rear terminal panel. One or two electromechanical alarm relays are available to activate external equipment when preset alarm set points are reached. Each of the two alarms can be set to monitor two independent set points. Each alarm setpoint can be either high or low alarm. The alarm type can be selected to be either of the inputs, the Process Variable, Deviation, Output, Shed from communications or to alarm on manual mode. It can also be used as an On or Off event at the beginning or end of a Ramp/Soak segment. The alarm hysteresis is configurable from 0 to 100% of range.

Indicators - They provide alarm,
control mode, and temperature units indication. There is also indication of when Remote Setpoint is active, the status of the control relays, and whether a setpoint program is in Run or Hold mode.
A 21-segment bargraph displays deviation to ±10% of span and an “On-Control” indicator.
Displays - A 4-digit upper display is dedicated to the process vari­able during normal operation with alternate 6-character information displayed when in the configure mode.
During normal operation, the lower display shows key-selected operat­ing parameters such as Output, Setpoints, Inputs, Deviation, active Tuning Parameter Set, Timer Status, or minutes remaining in a setpoint ramp (4 digits). It also provides guidance, through prompts, for the operator during controller configuration (8-characters).
