Figure 1 - UDC3000 Versa-Pro Controller

Dual Displays - Vacuum fluorescent alphanumeric displays and indicators with dedicated PV display.

Deviation Bargraph - “On Control” indication or up to ± 10% deviation display.

Easy Configuration - Multilanguage prompts, in programmed sequence, provide guidance during configuration. Individual, reliable tactile keys provide positive operator feedback. There are no internal jumpers to set.

Universal Isolated Input -

Input 1 accepts 10 thermocouple types, RTDs, Radiamatic RHs, mA, mV or voltage inputs through keyboard configuration. It is isolated from Input 2 and all other circuits. (See Table 1.)

Thermocouple Failsafe -

Configurable upscale or downscale burnout and failsafe output level.

Decimal Point Location -

Configurable for none, one, or two places.

Accutune IITM - Provides a new, 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 - This new feature 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.

Manual/Automatic Modes -

Bumpless, balanceless transfer between control modes.

Two Local Setpoints - Can be configured to provide two local setpoints, keyboard or optional remote switch selectable.

Universal Switching Power -

Operates on any line voltage from 90 to 264 Vac 50/60 Hz without jumpers. 24V ac/dc instrument power available as an option.

Limit Control - provides a latching relay which is activated whenever the PV goes above or below a preset setpoint value. An alarm indicator will light when the output is activated. Reset is through a key on the front of the controller or an external switch.

Setpoint Rate - Lets you define a ramp rate to be applied to any local setpoint change. A separate upscale or downscale rate is configurable. A single setpoint ramp is also available as an alternative.

Disable adaptive tune

Transmitter Power - Provides up to 30 volts to power a 2 wire transmitter (requires use of alarm 2 open collector output selection or auxiliary output.)

* AuxOut and communications are mutually exclusive (only one may be specified).

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 Types

The following output types are available per the model selection guide:

Current output

Electromechanical relays

Solid state relays

Open collector output

Solid state relay (10 amp) externally mounted (optional)

Auxiliary current output (optional)

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.
