Introduction
Analog Inputs
The UDC3500 has three universal analog inputs with a typical accuracy of ±0.10% of
full-scale input and a typical resolution of 16 bits. These can be configured to act as one
Universal and four High Level Inputs for a total of five analog inputs. All analog inputs
are sampled six times per second (every 166 ms).
The Process Variable input can be one of the various thermocouple, RTD, Radiamatic or
linear actuations. Linear actuations have thermocouple, RTD, and Radiamatic transmitter
characterization capability as a standard feature. Linear actuations also have square root
capability.
The optional second and third inputs are isolated from each other and all other inputs and
outputs and accept the same actuations as input one. Input 3 provides the Slidewire input
for Position Proportional control. These optional inputs can each be split into two high
level inputs. The fourth input is enabled by first configuring Input 2 as a 20 mA or 5 Vdc
type (high level) input and moving a jumper on the Second Optional Input Board. Input 4
will then be available as a high level input. The fifth input is enabled by first configuring
Input 3 as a 20 mA or 5 Vdc type (high level) and moving a jumper on the Third Optional
Input Board. Input 5 will then be available as a high level input.
All actuations and characterizations are keyboard configurable. Cold junction
compensation is provided for thermocouple type inputs. Upscale, downscale or failsafe
sensor break protection is keyboard configurable. A configurable digital filter of 0 to 120
seconds provides input signal damping.
Thermocouple Health—In addition to the standard configurable upscale, downscale or
failsafe output burnout selections, the condition of the thermocouple can be monitored to
determine if it is good, failing or in danger of imminent failure.
Math Functions
Algorithm—Two pre-configured algorithms are available for easy implementation. This
includes the capability of using a Ratio and Bias with any input. You can select from the
following menu:
Feedforward Summer—Uses any input, followed by a Ratio/Bias calculation, summed
directly with the computed PID output value to provide a resultant output to the final
control element (standard feature).
Weighted Average —Computes the weighted average of a PV or SP for the control
algorithm from two inputs (standard feature).
Feedforward Multiplier—Uses any input, multiplied by the calculated PID output to
provide a resultant output, which is sent to the final control element (standard feature).
Summer/Subtractor—Will add or subtract inputs with the result used as the derived PV.
Multiplier/Divider—Uses the analog inputs to calculate a derived PV. It is available
with or without Square Root.
Input High/Low Select—Specifies the PV input as the higher or lower of two inputs.

Introduction
8 Segment Characterizers—Two characterizers are available that can be applied to any
Analog Input, to Loop 1 Output or to Loop 2 Output. The Characterizers can be
combined to produce a single 16-segment characterizer.
Totalizer—Calculates and displays the total flow volume as measured by any of the
analog inputs or as derived by either Math algorithm. Displayed value is eight digits with
a configurable scaling factor. The totalizer value may be reset.
Combinational Inputs—Inputs can be combined for use with Relative Humidity, %
Oxygen, Carbon Potential, Dewpoint or Math Algorithms. This controller can accept
carbon probes from Cambridge, Marathon Monitors, Corning, A.A.A.C, Barber
Coleman, MacDhui, Bricesco or Furnace Controls.
Polynomial Curve Characterizer—A fifth order polynomial equation can be used on
any one of the analog inputs.
Logic Gates—Five Logic Gates configurable as OR, NOR, AND, NAND, XOR, XNOR,
or COMPARATOR. Each Gate has two inputs and one output. The Gates may be linked
together to perform more complex functions.
Digital Inputs
Four isolated digital inputs are provided for remote dry contact closure to select one of 25
actions. Also, two of these digital inputs can allow one of six additional selections to be
combined with one of the above selections.
Outputs
Output Types - The UDC3500 may have up to seven of the following outputs:
•
Current Outputs (4-20 or 0-20 mA)
•
Electromechanical Relays (5 amps)
•
Solid State Relay (1 amp)
•
Dual Electromechanical Relays (2 amps)
•
Open Collector Output (+30 VDC @ 20 mA)
Alarms
Up to four electromechanical alarm relays are available to activate external equipment
when preset alarm setpoints are reached. Each of the four alarms can be set to monitor
two independent setpoints. 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, PV rate of change, or to alarm on manual mode
activation or a Current Output Open failure. It can also be used as an On or Off event at
the beginning or end of a Ramp/Soak segment. An individual alarm hysteresis setting is
provided for each relay and these are configurable from 0 to 100% of range.
• Alarms can be configured as latching or non-latching.

A communications link is provided between the UDC3500 and a host computer or PLC
via the RS422/485 Modbus® RTU or Ethernet TCP/IP * communications option. An
infrared communication link is also available allowing a non-intrusive configuration of
the instrument.
Miscellaneous Features
Auxiliary Output * (optional)—All of the three current outputs can function as Auxiliary
Outputs which can be scaled from 4-20 ma for 0 to 100% for any range. These can be
configured to represent any analog input, PV, active Setpoint, Local SP1, Deviation, or
the Control Output for either control loop.
Transmitter Power—This feature provides up to 30 volts dc to power a 2-wire transmitter (requires the use of open collector output selection or one of the current outputs).
Four Local and one Remote Setpoints—Can be configured to provide four Local and
one Remote Setpoints, which are selectable either via the keyboard or by Digital Input.
Universal Switching Power—Operates on any line voltage from 90 to 264 Vac 50/60 Hz
without jumpers. 24 Vac/dc instrument power is available as an option.
Timer—This standard feature provides a configurable time period of 0 to 99 hours, 59
minutes or units of minutes and seconds. It can be started via the keyboard, alarm 2, or by
a digital input. The timer output is Alarm 1, which energizes at the end of the Timer
Period. Alarm 1 can be automatically reset. The Timer Period can be changed between
each batch. Status is shown on the lower display.
Healthwatch—Consists of three timers and three counters, which can each be assigned to
track UDC3500 controller functions. Selected Maintenance & Diagnostic data can be
accessed from the front panel or via communications. Alarms can be configured to
activate when a desired threshold is reached. A security code is required to perform
resetting of any of the above listed counter or timer functions.
Real Time Clock—An optional battery-backed clock feature that allows the user to
perform such things as starting an SP Program on a specific date and time.
Auto/Manual Station Plus Back-up Control—A UDC3500 can act as both an
Auto/Manual Station PLUS as a back-up PID Controller, should the primary loop
controller fail. Since the PID control is sometimes implemented via a PLC, this feature
provides a very cost-effective way to insure the process does not have to shutdown or

Introduction
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.
Moisture Protection—The NEMA4X and IP66 rated front face permits use in
applications where it may be subjected to moisture, dust, or hose-down conditions. UL
and CSA approved as Type 4 protection.
Setpoint Ramp/Soak Programming (Optional)—Enables you to program and store ten
Ramp and ten Soak segments (total of twenty segments) for setpoint programming. Run
or Hold of program is keyboard or remote digital switch selectable.
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.
Output Rate Limiter—A maximum output rate may be configured for both the upscale
and the downscale output directions.
CE Mark—Conformity with 73/23/EEC, Low Voltage Directive and 89/336/EEC, the
EMC Directive as a standard feature.
Approval Body Options—CSA certification and UL listing are available as an option.
Four Sets of Tuning Constants—Four sets of PID parameters can be configured for each
loop and automatically or keyboard selected.
Data Security—Five levels of keyboard security protect tuning, configuration, and
calibration data, accessed by a configurable 4-digit code. Nonvolatile EEPROM memory
assures data integrity during loss of power.
Diagnostic/Failsafe Outputs—Continuous diagnostic routines detect failure modes,
trigger a failsafe output value and identify the failure to minimize troubleshooting time.
High Noise Immunity—The controller is designed to provide reliable, error-free
performance in industrial environments that often affect highly noise-sensitive digital
equipment.
Accutune III™ —This standard feature provides a 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 speeds up and
simplifies start-up plus allows retuning at any setpoint. The algorithm used is an
improved version of the Accutune IITM algorithm found on earlier controllers. Two
possibilities are now offered when tuning your process: Fast Tune and Slow Tune.
Fast Tune will tune the process in such a way that the temp is reached faster, a
slight overshoot will be allowed.
Slowtune will minimize overshoot, but it will take more time for the process
temperature to reach the target setpoint.
Heat/Cool (Duplex Tune) will automatically tune both the heating and cooling
sides of the process.

Introduction
Fuzzy Logic—This standard feature uses fuzzy logic to suppress process variable
overshoot due to SP changes or externally induced process disturbances. It
operates independently from Accutune III 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.
* The Second Current Output option is mutually exclusive with the Ethernet
Communications option.

Introduction
Infrared communications
The infrared connection provides a non-intrusive wireless connection with the instrument
and maintains NEMA4X AND IP66 integrity.
No need to get access to the back of the controller to communicate with the instrument,
no need to take your screw driver to wire the communication cable, no wiring mistake
possible. You can now duplicate an instrument’s configuration, upload or download a
new configuration in a matter of seconds, just by pointing your Pocket PC in the direction
of the instrument.
It takes just a few seconds to upload a configuration from an instrument. You can then
save the configuration file onto your PC or pocket PC for review, modification or
archiving. Furthermore, this software also gives you important maintenance information
on the controller: instantly, get information on the current operating parameters, digital
inputs and alarm status, identify internal or analog input problems.
Question: What if I have several controllers on the same panel? How can I be sure I am
communicating with the correct one?
Answer: The infrared port of the controller is normally “off”. You activate the infrared
port by pressing any controller’s key. You can now communicate. After 4 minutes, the
port will be shut down again. Each controller may also be assigned a different
communications address.

2.6 Wiring
2.6.1 Electrical Considerations
Line voltage wiring
This controller is considered “rack and panel mounted equipment” per EN61010-1,
Safety Requirements for Electrical Equipment for Measurement, Control, and Laboratory
Use, Part 1: General Requirements. Conformity with 72/23/EEC, the Low Voltage
Directive requires the user to provide adequate protection against a shock hazard. The
user shall install this controller in an enclosure that limits OPERATOR access to the rear
terminals.
Mains Power Supply
This equipment is suitable for connection to 90 to 264 Vac or to 24 Vac/dc 50/60 Hz,
power supply mains. It is the user’s responsibility to provide a switch and non-time delay
(North America), quick-acting, high breaking capacity, Type F (Europe), 1/2A, 250V
fuse(s), or circuit breaker for 90-264 Vac applications; or 2 A, 125 V fuse or circuit
breaker for 24 Vac/dc applications, as part of the installation. The switch or circuit
breaker shall be located in close proximity to the controller, within easy reach of the
OPERATOR. The switch or circuit breaker shall be marked as the disconnecting device
for the controller.
Applying 90-264 Vac to an instrument rated for 24 Vac/dc will severely
damage the instrument and is a fire and smoke hazard.
When applying power to multiple instruments, make certain that sufficient current is
supplied. Otherwise, the instruments may not start up normally due to the voltage drop
caused by the in-rush current.
Controller Grounding
PROTECTIVE BONDING (grounding) of this controller and the enclosure in which it is
installed shall be in accordance with National and Local electrical codes. To minimize
electrical noise and transients that may adversely affect the system, supplementary
bonding of the controller enclosure to a local ground, using a No. 12 (4 mm2) copper
conductor, is recommended.
Control/Alarm Circuit Wiring
The insulation of wires connected to the Control/Alarm terminals shall be rated for the
highest voltage involved. Extra Low Voltage (ELV) wiring (input, current output, and
low voltage Control/Alarm circuits) shall be separated from HAZARDOUS LIVE (>30
Vac, 42.4 Vpeak, or 60 Vdc) wiring per Permissible Wiring Bundling, Table 2-5.
Electrical Noise Precautions
Electrical noise is composed of unabated electrical signals, which produce undesirable
effects in measurements and control circuits.
22
UDC3500 Universal Digital Controller Product Manual
10/05
Installation
Digital equipment is especially sensitive to the effects of electrical noise. Your controller
has built-in circuits to reduce the effect of electrical noise from various sources. If there
is a need to further reduce these effects:
•
Separate External Wiring—Separate connecting wires into bundles
(See Permissible Wiring Bundling - Table 2-5) and route the individual bundles
through separate conduit metal trays.
Use Suppression Devices—For additional noise protection, you may want to add
suppression devices at the external source. Appropriate suppression devices are
commercially available.
ATTENTION
For additional noise information, refer to document number 51-52-05-01, How to Apply Digital
Instrumentation in Severe Electrical Noise Environments.

2.7 Wiring Diagrams
Identify Your Wiring Requirements
To determine the appropriate diagrams for wiring your controller, refer to the model
number interpretation in this section. The model number of the controller is on the
outside of the case.
Output Functionality and Restrictions
Table 2-6 and Table 2-7 show the control functionality and number of alarms that are
available based upon the installed outputs quantity and type. First, use the left-most
column to find the Control Output Algorithm desired for your instrument. Then use the
second column to find the Output 2 Option selection installed in your instrument. The
rest of the columns will then show how the instrument delivers your desired Output
functionality and the quantity of alarms available.
In Table 2-6, “HEAT” is used as meaning Loop 1 Control Output #1 and “COOL” is
used as meaning Loop 1 Control Output #2. When Position Proportional or Three
Position Step Control (TPSC) is configured, then “HEAT” means OPEN while “COOL”
means CLOSE.
In Table 2-7, “Loop 2 HEAT” is used as meaning Loop 2 Control Output #1 and “Loop 2
COOL” is used as meaning Loop 2 Control Output #2.
See Figure 2-4 Composite Wiring Diagram, for information on where the customer
terminals are for all of these outputs and alarms.
ATTENTION
The selection for Loop 1 Output takes precedence over the selection for Loop 2 Output.
For example, if you select the Loop 1 Output Algorithm as Current Duplex 50%, then
you cannot have Current Duplex 50% as the Output Algorithm for Loop 2.
The Output 2 option shown in these tables as “Single Relay” can be any of the
following selections: Electro-Mechanical Relay, Solid-State Relay or Open Collector
Output.
If the controller is configured to use the same relay for more than one function, then the
following priority is used to determine how the relay functions: Control Outputs take
precedence over Alarms, which in turn take precedence over Time/Events, which in turn
take precedence over Logic Gate Outputs.
For example, if you select the Loop 2 Output Algorithm as Time Simplex (which uses
Relay 3), enable Alarm 3 (which also uses Relay 3) and configure a Logic Gate to use
Relay 3, then the instrument will use Relay #3 to perform the Time Simplex output and
ignore the Alarm and Logic Gate functions.

1 PROTECTIVE BONDING (grounding) of this controller and the enclosure in which it is
installed, shall be in accordance with National and local electrical codes. To minimize
electrical noise and transients that may adversely affect the system, supplementary
bonding of the controller enclosure to local ground using a No. 12 (4 mm 2) copper
conductor is recommended. Before powering the controller, see “Prelimnary Checks” in
this section of the Product Manual.
2 It is the user’s responsibility to provide a switch and non -time delay (North America),
quick-acting, high breaking capacity, Type F (Europe), 1/2A, 250V fuse(s), or circuit breaker for 90-264 Vac applications; or 2 A, 125 V fuse or circuit breaker for 2 4 Vac/dc
applications, as part of the installation.
3
Applying 90-264 Vac to an instrument rated for 24 Vac/dc will severely
damage the instrument and is a fire and smoke hazard.

This controller does not produce a steady current for burnout detection. For that reason, when a
thermocouple is used in parallel with another instrument, it may be desirable to configure the burnout
selection for this controller to “NOFS” and use the burnout current from the other instrument to also drive
this controller. The Failsafe Output must be set to ensure proper operation when the thermocouple fails.
3
The 250 ohm resistor for milliamp inputs or the voltage divider for 0 to10 Volt or –1 to 1Volt inputs are
supplied with the controller when those inputs are specified. These items must be installed prior to start up
when the controller is wired. For 0-20 mA, -1 to 1 Volt and 0-10 Volt applications, the resistor should be
located at the transmitter terminals if Burnout detection is desired.
4
Splice and tape this junction between the two thermocouples. This junction may be located anywhere
between the thermocouples and the instrument terminals, it does not need to be close to the other
thermocouple junctions. Both thermocouples must be of the same type. For the highest accuracy, the
thermocouples should be matched or, preferably, made from the same batch of wire.
5
The millivolt values for the Thermocouple Differential Input are for a pair of J thermocouples at an ambient
temperature mean of 450°F / 232°C. Cold Junction Compensation is not required for this input type.

Instruments equipped with the Ethernet Communications Option come with an Ethernet
Adaptor Kit. To use this kit, first remove the four screws on your instrument from
Terminal Block positions 24 through 27. Place the Ethernet Adaptor Board on to the
terminal block as shown and then secure it in place with the four long screws provided in
the kit. Route the long wire on the Ethernet Adaptor Board over to Terminal #4 on your

instrument. The RJ-45 connector on the Ethernet Adaptor Board will allow you to use a
straight-through cable to connect the controller to a MDI Compliant Hub or Switch.
Alternatively, you may use a crossover cable to connect your controller directly to a PC,
which is useful for commissioning purposes. Use only Category 5 (STP CAT5) shielded
twisted-pair Ethernet cables. For strain relief, secure your Ethernet cable to the controller
with the tie wraps included in the kit using the holes in the bottom controller flange.

3.1 Overview
Introduction
Configuration is a dedicated operation where you use straightforward keystroke
sequences to select and establish (configure) pertinent control data best suited for your
application.
To assist you in the configuration process, there are prompts that appear in the upper and
lower displays. These prompts let you know what group of configuration data (Set Up
prompts) you are working with and also, the specific parameters (Function prompts)
associated with each group.
Table 3-1 shows an overview of the prompt hierarchy as it appears in the controller.

3.3 Configuration Procedure
Introduction
Each of the Set Up groups and their functions are pre-configured at the factory.
The factory settings are shown in Table 3-4 through Table 3-21. If you want to change
any of these selections or values, follow the procedure in Table 3-3. This procedure tells
you the keys to press to get to any Set Up group and any associated Function prompt.
Procedure
ATTENTION
The prompting scrolls at a rate of one group every 2/3 seconds when the SET UP or FUNC/LOOP 1/2 key
or
is held in. Also,
keys will move group prompts forward or backward twice as fast.

3.4 Loop 1 Tuning Set Up Group
Introduction
Tuning consists of establishing the appropriate values for the tuning constants you are
using so that your controller responds correctly to changes in process variable and
setpoint. You can start with predetermined values but you will have to watch the system
to see how to modify them. The Accutune feature automatically selects Gain, Rate, and
Reset on demand.
There can be as many as four PID sets available for Loop 1.
ATTENTION
Because this group contains functions that have to do with security and lockout, we recommend
that you configure this group last, after all other configuration data has been loaded.

Parameter
Definition
PROPORTIONAL BAND (simplex) is the percent of
the range of the measured variable for which a
proportional controller will produce a 100 % change
in its output.
GAIN is the ratio of output change (%) over the
measured variable change (%) that caused it.
100%
G = PB%
where PB is the proportional band (in %)
If the PB is 20 %, then the Gain is 5. And, at those
settings, a 3 % change in the error signal (SP-PV)
will result in a 15 % change in the controller’s output
due to proportional action. If the Gain is 2, then the
PB is 50 %.
Also defined as “HEAT” Gain on Duplex models for
variations of Heat/Cool applications.
The selection of Proportional Band or Gain is made
in the CONTROL parameter group under prompt
PBorGAIN.
RATE MIN
0.00 to 10.00 minutes
RATE action, in minutes, affects the controller’s
output whenever the deviation is changing; and
affects it more when the deviation is changing faster.
Also defined as “HEAT” Rate on Duplex models for
variations of Heat/Cool applications.

RSET MIN = Reset in Minutes per Repeat
RSET RPM = Reset in Repeats per Minute
RESET (or Integral Time) adjusts the controller’s
output in accordance with both the size of the
deviation (SP–PV) and the time that it lasts. The
amount of the corrective action depends on the
value of Gain. The Reset adjustment is measured as
how many times proportional action is repeated per
minute or how many minutes before one repeat of
the proportional action occurs.
Used with control algorithm PID-A or PID-B.
Also defined as “HEAT” Reset on Duplex models for
variations of Heat/Cool applications.
ATTENTION The selection of whether Minutes per
Repeat or Repeats per Minute is used is made in the
CONTROL parameters group under the prompt
MINorRPM.
MAN RSET

MANUAL RESET is only applicable if you use
control algorithm PD WITH MANUAL RESET in the
Algorithm Set Up group. Because a proportional
controller will not necessarily line out at setpoint,
there will be a deviation (offset) from setpoint. This
eliminates the offset and lets the PV line out at
setpoint.
ATTENTION Bias is shown on the lower display.

3.5 Loop 2 Tuning Set Up Group
Introduction
Tuning consists of establishing the appropriate values for the tuning constants you are
using so that your controller responds correctly to changes in process variable and
setpoint. You can start with predetermined values but you will have to watch the system
to see how to modify them. The Accutune feature automatically selects Gain, Rate, and
Reset on demand.
There can be as many as four PID sets available for Loop 2.

PROPORTIONAL BAND (simplex) is the percent of
the range of the measured variable for which a
proportional controller will produce a 100 % change
in its output.
GAIN is the ratio of output change (%) over the
measured variable change (%) that caused it.
100%
G = PB%
where PB is the proportional band (in %)
If the PB is 20 %, then the Gain is 5. And, at those
settings, a 3 % change in the error signal (SP-PV)
will result in a 15 % change in the controller’s output
due to proportional action. If the Gain is 2, then the
PB is 50 %.
Also defined as “HEAT” Gain on Duplex models for
variations of Heat/Cool applications.
The selection of Proportional Band or Gain is made
in the CONTROL parameter group under prompt
PBorGAIN.
RATE5MIN
0.00 to 10.00 minutes
RATE action, in minutes, affects the controller’s
output whenever the deviation is changing; and
affects it more when the deviation is changing faster.

RESET (or Integral Time) adjusts the controller’s
output in accordance with both the size of the
deviation (SP–PV) and the time that it lasts. The
amount of the corrective action depends on the
value of Gain. The Reset adjustment is measured as
how many times proportional action is repeated per
minute or how many minutes before one repeat of
the proportional action occurs.
Used with control algorithm PID-A or PID-B.
Also defined as “HEAT” Reset on Duplex models for

3.6 SP Ramp Set Up Group
Introduction
Set Point Ramp, Set Point Programs and Set Point Rates can be configured in this group.
A single Setpoint Ramp [SP RAMP] can be configured to occur between the current local
setpoint and a final local setpoint over a time interval of from 1 to 255 minutes.
A Set Point Rate [SPRATE] lets you configure a specific rate of change for any local
setpoint change.
A single Set Point Program [SP PROG] with up to 20 segments can be configured.
For more information on Set Point Rate, Ramp and Programming, see Sections 4.27
through 4.30.
You can start and stop the ramp/program using the RUN/HOLD key.
PV Hot Start is a configurable feature and means that, at initialization, the setpoint is set
to the current PV value and the Ramp or Rate or Program then starts from this value.
Added Features not found in other UDC products:
•
20 segments instead of 12
•
10 Guaranteed Soak Settings (one for each Soak Segment)
•

3.7 Accutune Set Up Group
Introduction
Accutune III automatically calculates GAIN, RATE, and RESET TIME (PID) tuning
constants for your control loop. When initiated on demand, the Accutune algorithm
measures a process step response and automatically generates the PID tuning constants
needed for no overshoot on your process.
The Accutune III set up group offers these selections:
Fuzzy, Fuzzy Overshoot Suppression: When enabled, this configuration will suppress
or eliminate any overshoot that may occur as a result of the existing tuning
parameters, as the PV approaches the setpoint.
Tune, Demand Tuning: This tuning cycles the output to the output limits causing the
PV to oscillate around the SP value. This tuning does not require the process to be at
lineout (stabilized) and may be moving. The tuning process is initiated through the
operator interface keys or via a digital input (if configured). The algorithm then
calculates new tuning parameters and enters them in the tuning group. Tune will
operate with PIDA, PIDB, PD+MR and Three Position Step Control algorithms.
SP, SP Tuning: When activated in automatic control, the output makes an output step
in the direction of the SP and starts measurement activities to calculate the tuning
parameters based on the PV response. In order to work properly, this tuning requires
that the process be at lineout (stabilized) for a period before SP Tune is initiated.
SP tuning continuously adjusts the PID parameters in response to setpoint changes.
You can select tuning on minimum setpoint changes of 5 % up to 15 % span.
Perform SP tuning after you have configured the controller. SP Tuning does not
operate with the Three Position Step Control algorithm.
Tune + PV or SP + PV, PV Tuning: The (TUNE) Demand Tuning or the (SP) Setpoint
Tuning portions of these selections work as stated above. PV Adapt will occur during
Process Variable (PV) disturbances (0.3% span or larger) which result from nonlinearities, process dynamics, load changes, or other operating conditions. When this
condition exists, the controller monitors the process response for 1 and 1/2 process
cycles around the setpoint to determine whether there has been a true process change
or a momentary upset.
Process retuning occurs as the process dynamics are learned. When the process is
being learned with possible retune, a “t” is shown in the upper left display digit.
Simplex Tuning is used when a Simplex Control Algorithm is configured and uses the
current SP value and alters the output over the Output Limit Range.
Duplex Tuning is used when a Duplex Control Algorithm is configured. To perform a
Duplex Tune, Two Local Setpoints must be configured per the Control Group in
Section 3.17.
See Section 4.10 for additional information.

TUNE is the recommended start-up mode—to be
used when no knowledge of the process tuning
values is available. In the Start-up mode, after
enabling ACCUTUNE, the operator simply
configures the desired SP value and enables the
ACCUTUNE process via the keyboard.

The Timer section allows you to configure a time-out period and to select the timer start
by either the keyboard (RUN/HOLD key) or Alarm 2. An optional digital input can also be
configured to the start the timer. The timer display is selectable as either “time
remaining” (see TI REM) or “elapsed time” (see E TIME).
Alarm 1 is activated at the end of the time-out period. When the timer is enabled, it has
exclusive control of the alarm 1 relay—any previous alarm 1 configuration is ignored. At
time-out, the timer is ready to be activated again by whatever action has been configured.

CONTROL ALGORITHM FOR LOOP 1—The
Control Algorithm lets you select the type of control
that is best for your process.
ON-OFF
ON/OFF—The simplest control type. The output can
be either ON (100 %) or OFF (0 %). The Process
Variable (PV) is compared with the setpoint (SP) to
determine the sign of the error (ERROR = PV–SP).
The ON/OFF algorithm operates on the sign of the
error signal.
In Direct Acting Control, when the error signal is
positive, the output is 100 %; and when the error
signal is negative, the output is 0 %. If the control
action is reverse, the opposite is true. An adjustable
overlap (Hysteresis Band) is provided between the
on and off states.
ATTENTION Other prompts affected: OUT HYST
DUPLEX ON/OFF—This is an extension of the ONOFF algorithm when the output is configured for a
Duplex control algorithm. It allows the operation of a
second ON/OFF output. There is a deadband
between the operating ranges of the two inputs and
an adjustable overlap (hysteresis) of the on and off
states of each output. Both Deadband and
Hysteresis are separately adjustable. With no relay
action the controller will read 50 %.

PID A
ATTENTION PID A
should not be used for
Proportional only action;
i.e., no integral (reset)
action. Instead, use
PD+MR with rate set to 0.
Parameter
Definition
PID A—This normally used for three-mode control.
Three mode control means that the output can be
adjusted to be at any point between 0 % and 100 %.
It applies all three control actions—Proportional (P),
Integral (I), and Derivative (D)—to the error signal.
Proportional (Gain)—Regulates the controller’s
output in proportion to the error signal (the difference
between Process Variable and Setpoint).
Integral (Reset)—Regulates the controller’s output
to the size of the error and the time the error has
existed. (The amount of corrective action depends
on the value of proportional Gain.)
Derivative (Rate)—Regulates the controller’s output
in proportion to the rate of change of the error. (The
amount of corrective action depends on the value of
proportional Gain.)
PID B
PID B—Unlike the PID A equation, the controller
gives only an integral response to a setpoint change,
with no effect on the output due to the gain or rate
action, and it gives full response to PV changes.
Otherwise controller action is as described for the
PID A equation. See note on PID A.
PD+MR
PD WITH MANUAL RESET—This is used whenever
integral action is not wanted for automatic control
action. The equation is computed with no integral
contribution. The MANUAL RESET value, which is
operator adjustable, is then added to the present
output to form the controller output.
Switching between manual and automatic mode is
bumpless (output does not change value).
If you select PD with Manual Reset you can also
configure the following variations:
• PD (Two Mode) control,
• P (Single Mode) control.
Set Rate (D) to 0.

THREE POSITION STEP—The Three Position Step
Control algorithm allows the control of a valve (or
other actuator) with an electric motor driven by two
controller relay outputs; one to move the motor
upscale, the other downscale without a feedback
slidewire linked to the motor shaft. The deadband is
adjustable in the same manner as the duplex output
algorithm.
The Three Position Step Control algorithm provides
an output display (OUT), which is an estimated
motor position, since the motor is not using any
slidewire feedback. Although this output indication is
only an approximation, it is “corrected” each time the
controller drives the motor to one of its stops (0 % or
100 %). It avoids all the control problems associated
with the feedback slidewire (wear, dirt, noise). When
operating in this algorithm, the estimated OUT
display is shown to the nearest percent (i.e., no
decimal). This selection forces the Output Algorithm
selection to “POSPROP”. See Subsection 3.11.
Refer to the Operation section for motor position
displays.
As a customer configurable option, when a third
input board is installed, the motor slidewire can be
connected to the controller. The actual slidewire
position is then shown on the lower display as POS.
This value is used for display only. It is NOT
used in the Three Position Step algorithm. To
configure this option, set Input 3 actuation to
SLIDEW and then calibrate Input 3 per Subsection
6.5.

•
The Carbon and Dewpoint selections will automatically set Input 1 actuation to CARBON.
The Oxygen selection will automatically set Input 1 actuation to OXYGEN.
•
Input 2 can be any input actuation, but it is normally a type K, R or S thermocouple input,
depending upon the probe type selected.
•
All calculations are performed by the Controller, with Percent Carbon, Percent Oxygen or
Dewpoint shown as the PV display. The actual value of each analog input may be viewed via the
lower display.
•
For all Carbon Types, if the value of Percent Carbon falls below 0.1% - such as can happen when
the Carbon Probe voltage output falls below 900 mVdc – then the Controller will continue to
update the PV display, but the accuracy is unspecified. Likewise, if the measured temperature falls
outside of the specified ranges as noted above for the Carbon, Oxygen and Dewpoint input types,
then the Controller will continue to update the PV display, but the accuracy is unspecified.
•
For the Dewpoint algorithm, if the Carbon Sensor voltage falls below 800 mVdc, then the Dewpoint
is calculated as if the sensor voltage was at 800 mVdc.
•
If the Ratio for Input 2 is set to 0.0, then a constant value may be used for the Input 2 value via the
Input 2 Bias setting. When Input 2 Ratio is set to 0.0, the Input 2 low range and Sooting diagnostic
messages are disabled.

3.10 Logic Gates Set Up Group
Introduction
This Set Up Group is provided only as part of the Math Options package.
This group deals with various Logic Gates that are available for use in the controller. Up
to five different gates can be configured.
ATTENTION
If the controller is configured to use the same relay for more than one function, then the
following priority is used to determine how the relay functions: Control Outputs take
precedence over Alarms, which in turn take precedence over Time/Events, which in turn
take precedence over Logic Gate Outputs. For example, if you select the Loop 2 Output
Algorithm as Time Simplex (which uses Relay 3), enable Alarm 3 (which also uses
Relay 3) and configure a Logic Gate to use Relay 3, then the instrument will use Relay
#3 to perform the Time Simplex output and ignore the Alarm and Logic Gate functions.
Logic Gates are processed in numerical order. For example, if Logic Gate 2 and Logic
Gate 4 are configured in a contradictory manner, then Logic Gate 2 will take precedence
and Logic Gate 4 will be ignored.
Logic Gate Outputs configured for Relays will light an annunciator when active.
Outputs for Relay 1 through Relay 4 will light annunciators OUT 1 through 4. Logic
Gate Outputs for Relay 5 will light annunciator ALM 1.

ATTENTION
If the controller is configured to use the same relay for more than one function, then the
following priority is used to determine how the relay functions: Control Outputs take
precedence over Alarms, which in turn take precedence over Time/Events, which in turn
take precedence over Logic Gate Outputs. For example, if you select the Loop 2 Output
Algorithm as Time Simplex (which uses Relay 3), enable Alarm 3 (which also uses
Relay 3) and configure a Logic Gate to use Relay 3, then the instrument will use Relay
#3 to perform the Time Simplex output and ignore the Alarm and Logic Gate functions.
The Tuning Group is automatically configured to have two PID sets when a Duplex
Control Algorithm is selected.

configured for 4-20 mA or 0-20 mA operation via the
C1 RANGE configuration, below.
POSPROP
POSITION PROPORTIONAL—Type of output using
two relays to control a motor with a feedback
slidewire.
This output algorithm selection forces Input 3 to the
SLIDEW selection when the Control Algorithm is any
selection other than 3PSTEP.
ATTENTION Other prompts affected: DEADBAND.

CUR D
CURRENT DUPLEX—Similar to current simplex but
uses a second current output. The second output is
usually scaled so that zero and span correspond
with 0 % and 50 % output (cool zone). When the
output is 0 % to 50 %, the controller uses tuning
parameter set #2. When the output is 50 % to 100 %

CURRENT DUPLEX RANGE (SPLIT)—Split the
Control Output across two physical outputs. This
setting should be used for Relay/Current and
Current/Relay Duplex Outputs.
This setting should also be used when
Current/Current Duplex operation is desired. This
enables one current output to provide heat control
and another current output to provide cool control.
To enable Current/Current Duplex (split) operation:
• The Second Current Output or the Third Current in
the Options Set Up group must be selected for
Output.
• The Current Output selected (Second or Third) is
scaled as desired for 0-50 % controller output.
• Deadband for this configuration only applies to the
First Current Output. The other Current Output
must have the Deadband scaled in.
FOR EXAMPLE:
Current Duplex (split) using the First and Second
Current Outputs. If a 2 % Deadband is desired, then
enter 2.0 for the Deadband selection in the Control
Algorithm group. This will apply Deadband to the
First Current Output. In the Options group, set
Second Current Output actuation to OUTPUT, the
Second Current Output LOW VAL to 49.0 and the

Zero deviation will produce a center scale (12 mA or
50 %) output. A negative deviation equal in
magnitude to the Output High Scaling Factor will
produce a low-end output (4 mA or 0 %) output. A
positive deviation equal in magnitude to the Output
High Scaling Factor will produce a high-end output
(20 mA or 100 %).
FOR EXAMPLE: Configuration is as follows:
Input 1 = Type T High Thermocouple
PV range = –300 °F to +700 °F
PV span = 1000 °F
Deviation Range = –1000 to +1000 °F = 2000 °F
Second Current Output Low Scale Value = 0.0
Second Current Output High Scale Value = 1000
C2 Range = 4-20 mA
If PV = 500 °F and SP = 650 °F
then Deviation Display = –150 °F, which is
–150 / 2000 = –7.5% of the Deviation Range, so
Second Current Output = 50% – 7.5% = 42.5%

TRANSMITTER CHARACTERIZATION—This
selection lets you instruct the controller to
characterize a linear input to represent a non-linear
one. If characterization is performed by the
transmitter itself, then select LINEAR.
ATTENTION Prompt only appears when a linear
actuation is selected at prompt IN1 TYPE.
FOR EXAMPLE:
If Input 2 is a 4 to 20 mA signal, but the signal
represents a type K H thermocouple, then configure
K TC H and the controller will characterize the 4 to
20 mA signal so that it is treated as a type K
thermocouple input (high range).
Parameter definitions are the same as in IN2 TYPE.

ATTENTION For Burnout to function properly on 020 mA, 0-10 Volt or –1 to +1 Volt input types (or a 05V type that uses a dropping resistor), the dropping
resistor must be remotely located (across the
transmitter terminals). Otherwise, the input at the

CB OUT
CONTROL BLOCK OUTPUT—Output as calculated
by the control block (such as PID A). When using
one of the characterizers, OUTPUT is the output
value after it passes through the characterizer. CB
OUT is the control block output before it passes
through the characterizer.
ATTENTION CB OUT should not be used for Three

Control applications.
PV
PROCESS VARIABLE—Represents the value of
the Process Variable.
DEV
DEVIATION (PROCESS VARIABLE MINUS
SETPOINT)—Represents –100 % to +100 % of the
selected PV span in engineering units.
Zero deviation will produce a center scale (12 mA or
50 %) output. A negative deviation equal in
magnitude to the Output High Scaling Factor will
produce a low end output (4 mA or 0 %) output. A
positive deviation equal in magnitude to the Output
High Scaling Factor will produce a high end output
(20 mA or 100 %).
FOR EXAMPLE: Configuration is as follows:
Input 1 = Type T High Thermocouple
PV range = –300 °F to +700 °F
PV span = 1000 °F
Deviation Range = –1000 to +1000 °F = 2000 °F
Second Current Output Low Scale Value = 0.0
Second Current Output High Scale Value = 1000
CO Range = 4-20 mA
If PV = 500 °F and SP = 650 °F
then Deviation Display = –150 °F, which is
–150 / 2000 = –7.5% of the Deviation Range, so
Second Current Output = 50% – 7.5% = 42.5%
which is 0.425 X 16 mA + 4 mA = 10.8 mA

Introduction
The Communications group lets you configure the controller to be connected to a host
computer via Modbus® or Ethernet TCP/IP protocol.
Introduction
A controller with a communications option looks for messages from the host computer. If
these messages are not received within the configured shed time, the controller will
SHED from the communications link and return to stand-alone operation. You can also
set the SHED output mode and setpoint recall, and communication units.
Up to 99 addresses can be configured over this link. The number of units that can be
configured depends on the link length, with 31 being the maximum for short link lengths
and 15 drops being the maximum at the maximum link length.

3.21 Alarms Set Up Group
Introduction
The UDC3500 has four alarms and eight alarm setpoints. Each alarm has its own
hysteresis configuration.
An alarm is an indication that an event that you have configured (for example—Process
Variable) has exceeded one or more alarm limits. There are up to four alarms available.
Each alarm has two setpoints. You can configure each of these two setpoints to alarm on
various controller parameters.
There are two alarm output selections for each alarm setpoint, High and Low. These
allow you to choose whether the alarm activates when the measured value is above
(High) or below (Low) the alarm setpoint. You can also configure the two setpoints to
alarm on the same event and to alarm for both high and low conditions.
An adjustable Hysteresis of 0 % to 100 % is provided for each alarm.
Alarms may be conveniently broken up into four types:
1. Analog – These are alarms, which monitor selections that use analog values,
such as Process Variable, Set Points or analog inputs. These alarms require a
hysteresis value.
2. Digital – These are alarms which monitor status that are either ON or OFF,
such as Mode (e.g., Manual), Digital Input status. These alarms do not use a
hysteresis value.
3. Events – The alarms are only used with Set Point Programming and may be
configured to operate at the beginning or end of a particular segment.
4. Loop Break – Loop Break is a special kind of alarm, which monitors the
control loop. Although this is a digital alarm (i.e., the alarm is either broken or
it is not), it requires that an analog value to be configured in order to operate
properly.
See Table 2-3 in the Installation section for Alarm relay contact information.
ATTENTION
If the controller is configured to use the same relay for more than one function, then the
following priority is used to determine how the relay functions: Control Outputs take
precedence over Alarms, which in turn take precedence over Time/Events, which in turn
take precedence over Logic Gate Outputs. For example, if you select the Loop 2 Output
Algorithm as Time Simplex (which uses Relay 3), enable Alarm 3 (which also uses
Relay 3) and configure a Logic Gate to use Relay 3, then the instrument will use Relay
#3 to perform the Time Simplex output and ignore the Alarm and Logic Gate functions.
The prompts for the Alarm Outputs appear whether or not the alarm relays are
physically present or used for some other function. This allows the Alarm status to be
shown on the display and/or sent via communications to a host computer.

ATTENTION See NOTE 9 and NOTE 10.
ATTENTION
NOTE 1: When the controller is configured for Three Position Step Control, alarms set for Output will not
function.
NOTE 2: Alarm 1 is not available if the Timer is enabled because Alarm 1 is dedicated to Timer output.
NOTE 3: This Deviation Alarm is based upon deviation from whichever Local or Remote SP is active.
NOTE 4: Loop Break alarms monitor the selected control loop to determine if it is working. When enabled,
the control output is checked against the minimum and maximum output limit settings. When the output
reaches one of these limits, a timer begins. If the timer expires and the output has not caused the PV to
move by a pre-determined amount, then the alarm activates, thus signaling that the loop is broken. The
loop break timer value must be configured by the operator as the AxSx VAL entry. This value is in
seconds with a range of 0 to 3600 seconds. A setting of 0 is equivalent to an instantaneous loop break
when the output reaches one of its limit values.
The amount of PV Movement required is determined by the “UNIT” setting in the Display Setup Group.
For the Degrees F configuration, the PV must move by 3° in the time allowed. For the Degrees C
configuration, the PV must move by 2°in the time allowed. For the “NONE” selection, the PV must move
1% of the PV range in the time allowed.
Loop Break alarms do not have a HIGH/LOW State configuration, they are always assumed to be a HIGH
state alarm.
Only one alarm setpoint should be configured for Loop Break. If more than one is assigned, only one will
function as intended and the others will not operate.
NOTE 5: Thermocouple Warning means that the instrument has detected that a Thermocouple input is
starting to fail. This alarm also triggers if the Thermocouple further degrades to the Thermocouple Fail
stage or if the input fails. Not valid for input types other than Thermocouple types.
NOTE 6: Thermocouple Failing means that the instrument has detected that a Thermocouple input is in
imminent danger of failing. This alarm also triggers if the input fails. Not valid for input types other than
Thermocouple types.
NOTE 7: For Totalizer Alarms, the Alarm Setpoint value is based upon the configured Totalizer Scale
Factor (See Section 3.9).
For example:
Totalizer Scale Factor: *E4 = 1 x 104 = 10,000
Alarm Type: Totalizer
Alarm SP: 400
Alarm High / Low: HIGH
Alarm will activate when the Totalizer Value exceeds 400 x 104 = 4,000,000.

NOTE 8: The PV HOLD alarm will turn on whenever the instrument is put into the PV HOLD mode. The
Alarm Setpoint Value for this alarm is the number of seconds before the alarm turns on after the PV
HOLD mode starts.
NOTE 9: The setpoint values for Healthwatch Timer Alarms are in Hours and fractions of an hour. For
example, a setpoint value of 20.10 would be for twenty hours and six minutes.
NOTE 10: When both alarm setpoints for a particular alarm are configured for the same Healthwatch
timer or counter, then the first configured value turns on the alarm while the second value resets the timer
or counter and turns off the alarm. For example:
If:
Alarm 1 Setpoint 1 (AL1 SP1) is configured for TIMER 2
Alarm 1 Setpoint 2 (AL1 SP2) is configured for TIMER 2
Alarm 1 Setpoint 1 Value (A1S1 VAL) is configured for 10.00 (ten hours)
Alarm 1 Setpoint 2 Value (A1S2 VAL) is configured for 11.00 (eleven hours)
Then:
When Timer 2 reaches 10.00 hours, Alarm 1 will turn on
When Timer 2 reaches 11.00 hours, Alarm 1 will turn off and Timer 2 will be reset to 0.00
NOTE 11: The setpoint value for PV Rate alarms is in Engineering Units (EU) per minute.

Event setting is in addition to whatever the Alarm X Setpoint 2 Type (where X = 1, 2, 3 or 4) is configured
for and effectively acts as an OR condition. See Section 3.21.
NOTE 2: These prompts are loop dependent. When only one loop is configured, then both EVENT 1 and
EVENT 2 operate on Loop 1. When Two Loops or Cascade are configured, then these prompts for
EVENT 1 operate only on Loop 1, while these prompts for EVENT 2 operate only on Loop 2.
NOTE 3: These prompts appear only when the TIME 1 or TIME 2 configuration is “CALENDR”.
NOTE 4: These prompts appear only when the TIME 1 or TIME 2 configuration is “CALENDR” or

3.27 P.I.E. Tool Ethernet and Email Configuration Screens
Introduction
These screens only appear in instruments that have Ethernet Communications. Ethernet
and Email parameters can only be configured via the Process Instrument Explorer (P.I.E.
Tool®). The figures in this section show screen-shots of the Configuration Screens from
the PC version of the P.I.E. Tool®. Pocket PC Configuration Screens are generally
similar in format but smaller.
Ethernet Configuration Screen
This controller is shipped from the factory with the IP Address set to 10.0.0.2, the Subnet
Mask set to 255.255.255.0 and the Default Gateway set to 0.0.0.0. Consult your
Information Technologies (IT) representative as to how these should be configured for
your installation. The MAC address is printed on the product label located on the
instrument’s case.
These settings can be changed via the Ethernet Configuration Screen as shown in Figure
3-3.
See Section 4.32 – Configuring your Ethernet Connection for more information.
Figure 3-3 Ethernet Configuration Screen
10/05
UDC3500 Universal Digital Controller Product Manual
171
Configuration
WARNING
If you change the IP Address, you will no longer be able to communicate with the instrument via
Ethernet until you change the P.I.E. Tool’s IP Address setting in the “PC COMM SETUP” to
match the setting that is now in your controller.
Email Configuration Screen
This controller may be configured to support up to two Emails. Each Email can be sent to
a different address. Emails are sent only when the selected alarm transitions from the
OFF to the ON state.
Figure 3-4 Email Configuration Screen
This controller cannot receive Emails, so it is suggested that you configure the “From
Email:” window with a non-Email style address that will make it easy for you to
determine which controller sent the Email. For Email technical reasons, the entry in the
“From Email:” window cannot have spaces. See Figure 3-4.
If you do not know your SMTP IP Address for outgoing Email, then contact your
Information Technologies (IT) representative. If your PC is on the same LAN that will be
used by the controller and which also connects to the Email server, then the SMTP IP
Address may generally be found by opening a DOS shell and typing:
ping smtp.[your domain name and extension, i.e., “yourisp.com”]
172
UDC3500 Universal Digital Controller Product Manual
10/05
Configuration
The content of the Emails sent by this controller contains the Alarm that triggered the
Email, its settings and the current value (if applicable) of the monitored variable. For
example, the content of an Email triggered by Alarm 1 Setpoint 1 that is configured to
monitor Input 1 would look something like this:
Name: Alarm 1 SP1, Type: INPUT1, Event: HIGH/END, Value = 500.00,
Actual = 712.69
The content of an Email triggered by Alarm 2 Setpoint 1 that is configured to monitor
Digital Input 1 would look something like this:
Name: Alarm 2 SP1, Type: DIG IN1, Event: HIGH/END, Value = 0.00,
Actual = 0.00
ATTENTION
Instruments that do not have the Real Time Clock option will always send Email time-stamped
with the date that the Ethernet Software in the instrument was last modified. Instruments with
the Real Time Clock option will send Email time-stamped with the current time in the controller.
If the SMTP address on your network is changed, such as can happen when a server is
replaced, then you must reconfigure the Email SMTP IP address in this instrument to match.

4.3 Entering a Security Code
Introduction
The level of keyboard lockout may be changed in the Set Up mode. However, knowledge
of a security code number (0 to 9999) may be required to change from one level of
lockout to another. When a controller leaves the factory, it has a security code of 0 which
permits changing from one lockout level to another without entering any other code
number.
Procedure
If you require the use of a security code, select a number from 0001 to 9999 and enter it
when the lockout level is configured as NONE. Thereafter, that selected number must be
used to change the lockout level from something other than NONE.
ATTENTION Write the number on the Configuration Record Sheet in the configuration
section so you will have a permanent record.

ATTENTION
After changing a Local Setpoint value, if no other key is pressed, it then takes a minimum of thirty (30)
seconds elapsed time before the new value is stored in non-volatile memory. If controller power is
removed before this time, the new setpoint value is lost and the previous setpoint value is used at
power-up. If, after changing the LSP value, another key is pressed, then the value is stored
immediately.

SETPOINT
In automatic remote mode, the controller operates from the setpoint measured at the
remote setpoint input. Adjustments are available to ratio this input and add a
constant bias before it is applied to the control equation.
See Subsection 3.12 Input 1 or 3.14 Input 2.
MANUAL
In the manual mode, the operator directly controls the controller output level. The
process variable and the percent output are displayed. The configured High and
Low Output Limits are disregarded and the operator can change the output value,
using the increment and decrement keys, to the limits allowed by the output type
(0 % to 100 % for a time proportioning output or –5 % to 105 % for a current output).
MANUAL
CASCADE
In the manual cascade mode, both control loops are in manual although there is still only one
output active. This mode is used to bring both loops into a reasonable operation area, at
which point the unit is placed into the automatic cascade mode.
If Loop 1 is placed in Manual control mode, then Loop 2, if in auto, is then placed in a pseudomanual mode thereby eliminating output bumps when Loop 1 is returned to Automatic control
mode.

4.10 Accutune III
Introduction
Accutune III (TUNE) may be used for self-regulating and single integrating processes.
This autotuning method is initiated on-demand, typically at initial start-up.
There are no other requirements necessary, such as prior knowledge to the process
dynamics or initial or post tune process line-out to setpoint or manual output.
Also, the setpoint value is not required to change in order to initiate the tuning process,
but the controller must be in the Automatic mode to start tuning. The process need not be
in a static (lined out) state and may be dynamic (changing with a steady output).
Configuration check
Make sure:
• TUNE has been enabled see to Subsection 3.7 – Accutune Set Up Group for details.
Tuning indicators
A “T” will show in the leftmost alphanumeric of the upper display until tuning is
completed.
Operation
The Accutune III algorithm provides user-friendly, on-demand tuning in this controller.
No knowledge of the process is required at start-up. The operator simply initiates the
tuning while in the automatic mode.
Once Accutune III has been enabled in the TUNE setup group, either “SLOW” or
“FAST” tuning may be used. Which one is used is selected via the lower display during
normal operation.
For the SLOW selection, the controller calculates conservative tuning constants with the
objective of minimizing overshoot. If the controller determines that the process has
appreciable dead time, it will automatically default to use Dahlin Tuning, which produces
very conservative tuning constants. The SLOW selection may be useful for TPSC and
Position Proportional applications, as it reduces “hunt” problems for the motor. This
selection is also recommended for applications that have significant deadtimes.
10/05
UDC3500 Universal Digital Controller Product Manual
193
Monitoring and Operating the Controller
For the FAST selection, the controller calculates aggressive tuning constants with the
objective of producing quarter-damped response. Depending upon the process, this
selection will usually result in some overshoot. For this reason, it may be desirable to
enable the FUZZY tune selection. See Section 4.11. When Fuzzy tune is enabled, it will
work to suppress or eliminate any overshoot that may occur as a result of the calculated
tuning parameters as the PV approaches the setpoint. This selection is best suited for
processes with a single lag or for those that do not have any appreciable deadtime.
FUZZY tuning does not work well for processes that have appreciable deadtime.
The Accutune III tuning process will cycle the controller’s output two full cycles
between the low and high output limits while allowing only a very small Process
Variable change above and below the SP during each cycle. A “T” shows in the upper
display until tuning is completed.
At the end of the tuning process, the controller immediately calculates the tuning
constants and enters them into the Tuning group, and begins PID control with the correct
tuning parameters. This works with any process, including integrating type processes,
and allows retuning at a fixed setpoint.

Tune for Duplex (Heat/Cool)
Accutune for applications using Duplex (Heat/Cool) control.
The controller must be configured to have two local setpoints unless Blended Tuning is
desired (see below). See Subsection 3.17- Control Set Up Group for details on
configuring two local setpoints. During tuning, the Accutune III process assumes that
Local Setpoint 1 will cause a Heating demand (output above 50%), and the tuning
parameters calculated for that setpoint are automatically entered as PID SET 1. Likewise,
Accutune III assumes that Local Setpoint 2 will cause a Cooling demand (output less
than 50%), and the tuning parameters calculated for that setpoint are automatically
entered as PID SET 2.

To abort Accutune and return to the last previous operation (SP or output level), press
MAN-AUTO key to abort the Accutune process or increment from the “DO SLOW” or
“DO FAST” prompt to the “TUNE OFF” prompt.
Completing Accutune
When Accutune is complete, the calculated tuning parameters are stored in their proper
memory location and can be viewed in the TUNING Set up Group, and the controller
will control at the local setpoint using these newly calculated tuning constants.
4.11 Fuzzy Overshoot Suppression
Introduction
Fuzzy Overshoot Suppression minimizes Process Variable overshoot following a setpoint
change or a process disturbance. This is especially useful in processes that experience
load changes or where even a small overshoot beyond the setpoint may result in damage
or lost product.
How it works
The Fuzzy Logic in the controller observes the speed and direction of the PV signal as it
approaches the setpoint and temporarily modifies the internal controller response action
as necessary to avoid an overshoot. There is no change to the PID algorithm, and the
fuzzy logic does not alter the PID tuning parameters. This feature can be independently
Enabled or Disabled as required by the application to work with the Accutune algorithm.
Fuzzy Tune should not be enabled for processes that have an appreciable amount of
deadtime.

4.12 Using Two Sets of Tuning Constants
Introduction
You can use two sets of tuning constants for single output types and choose the way they
are to be switched. (this does not apply for Duplex control, which always uses two PID
sets).
The sets can be:
• keyboard selected,
• automatically switched when a predetermined process variable value is reached,
• automatically switched when a predetermined setpoint value is reached.
Set up Procedure

• select two sets,
• set the switch-over value,
• set tuning constant value for each set.

4.13 Input Math Algorithms
Introduction
If selected via Math options, this controller has two input algorithms available. Each
algorithm can be configured to provide a derived (calculated) PV or a derived Remote
Setpoint. Up to three inputs may be applied to the calculation. In addition, the two
algorithms may be “linked” to combine two calculations by configuring one algorithm to
be an input to the other algorithm.
Standard functionality
The following algorithms are provided as standard on all instruments with two or three
analog inputs: Weighted Average, Feedforward Summer, Feedforward Multiplier, or
Relative Humidity.
Math Options
The Math option provides additional algorithms plus two Characterizers, Totalizer, and
Polynomial functions.
Input algorithm selections
Algorithm selections are made in Section 3 – Configuration. The following function
prompts can be found in the Algorithm Set Up group:
IN ALG1
IN ALG2
These selections include the following algorithms:
Weighted Average
Feedforward Summer
Relative Humidity
Summer

8 Segment Characterizers
Characterizers are available as part of the Math Algorithm option. See Section 3.9.
8SEG CH1
Xn VALUE
Yn VALUE
8SEG CH2
Xn VALU2
Yn VALU2
An 8-segment characterizer can be applied to any Analog Input, Output 1, or Output 2.
When an Analog Input is used, the selected input’s Ratio and Bias are applied to the Xn
values. The characterizers can be linked in order to provide a single 16-segment
characterizer.
When one of the loop outputs is selected, the Xn Values are the output from the control
algorithm, and the Yn Output is the final control element action.
An example of an 8-segment characterizer can be found in Figure 3-2.
Totalizer
A Flow Totalizer is available as part of the Math Algorithm option. See Section 3.9..
This calculates and displays the total flow volume being measured by one of the analog
inputs. Alternatively, it can be applied to either Input Algorithm 1 or Input Algorithm 2
to totalize the compensated flow rate as being calculated by the selected algorithm.
The totalizer displays the current totalized flow value (up to seven digits maximum).
Seven scaling factors are available (from one to one million). The desired scaling factor
is applied to the calculated value to extend the maximum total flow range that can be
displayed.
Five integration rates are available to match the totalizer rate to the rate of flow being
measured. The rates are:
Engineering units (EU) per second
EU per minute
EU per hour
EU per day
Millions of units per day
The totalizer value is stored in nonvolatile memory once every eight hours. If power is
lost while the totalizer is in operation, the current value of the totalizer will be lost. When
power is restored, the totalizer will start operation for the last value stored in nonvolatile
memory. The Σ (Sigma) display will blink to indicate this condition. Reset the totalizer.
The totalizer can be reset from the keyboard whenever desired. The totalizer should
always be reset to initialize the counters whenever it is enabled.
Alarm on totalizer value
The alarm type configuration includes an Alarm on Totalizer value. This allows an alarm
setpoint value to be used to cause an alarm when exceeded. The alarm setpoint represents

the lowest four digits of the selected Totalizer Scale Factor and has a range from 0 to

Totalizer reset via Digital Input
Any of the Digital Inputs may be configured to reset the totalizer value.
4.14 Logic Gate Operation

The Logic Gate function lets you configure up to five Dual-Input Logic Gates.
The following gates have two Digital input sources and one Digital output.
OR
NOR
AND

The following comparator gates have two Analog input sources and one Digital output.
These comparator gates are used with Input B having a fixed hysteresis band of 0.1% of
the Input B span.

Gate configuration
Refer to Section 3.10 to make your configuration choices for the following function
prompts for each gate you want to configure:

INPUT B SOURCE
OUTPUT USE
Gate Operation
Section 3.10 contains information defining how the different gates operate. In Digital
(Binary) Logic, there are only two states that can be present; “0” meaning OFF and “1” –
meaning ON.
Section 3.10 also lists the types of gates available along with their truth tables. These
tables indicate what happens to the output of each gate with regard to the state of the
inputs.
The rules and regulations regarding the use of the logic gates are listed in Table 4-18.

Monitoring and Operating the Controller
Function
Alarms
Rules and Regulations
Alarms take precedent over gate outputs. For example,
no gate output will occur if the Logic Gate Output is
directed to Relay 5 if the Alarm 1 is also configured.
Output Algorithms
Output algorithms that use Relay outputs take
precedence over gate outputs. For example, no gate
output will occur if the Logic Gate Output is directed to
Relay 1 when a conflicting Loop 1 output algorithm is also
configured (for example: Time Simplex, Time Duplex,
etc.).
Communications
Communications takes priority over gate output as
follows:
• No Gate Output will occur if directed to Manual/Auto
and the Host computer places the unit (loop) into
Manual or Automatic mode.
• No Gate Output will occur if directed to
Local/Remote and the Host computer selects either
Local or Remote setpoint.
Gate output will resume when the Host computer puts the
unit (loop) into the monitor state or the unit sheds from the
Host.
Mode or Setpoint

Introduction
When you select “AM STA” (auto manual station) for one of the Digital Inputs, contact
closure on the selected Digital Input causes the controller to switch to Auto/Manual
Station mode. See Section 3.19.
Function
As shown in Figure 4-2, State 2 is the “A/M Station mode” where the programmable
logic controller (PLC) output is sent through the Auto/Manual Station. You can switch to
manual and change the output at the controller. (It uses PID set 2.)
State 1 is the “Backup PID mode” which is triggered by opening the digital input. (It uses
PID set 1.)

Monitoring and Operating the Controller
Description
The “AM STA” selection of digital input creates a repeater station when the digital input
is closed. This is accomplished by a multi-selection from the digital input menu.
• “ACTION” is forced as “DIRECT”.
• “CONT ALG” is forced as “PD+MR”.
• Active setpoint is forced to 2SP.
• The PV is switched to “PV 2IN”.
• The tuning parameters used are the second set of parameters.
When the switch is open the unit becomes a normal controller with “CONT ALG” of
“PID A”, using tuning parameters set 1, SP, PV as IN1 and “DIRECT” or “REVERSE”
as selected by customer configuration.
Input 1 is typically the PV of some upper controller and Input 2 is typically that
controller’s output. If the upper control fails, the upper device or some watchdog opens
the digital input switch and UDC3500 back-up PID A control is active.
When the upper control reactivates, the digital input switch is closed and the
Auto/Manual Station becomes a repeater station and allows the upper control output
signal to pass through.
Configuration
There are some things to consider when configuring the controller.
The PV range stays as the IN1 range, even while IN2 is the PV when the switch is
closed; therefore:
• The IN2 HI must be less than or equal to the IN1 HI.
(Suggest: IN2 HI = 100.0)
• The IN2 LO must be greater than or equal to the IN1 LO.
(Suggest: IN2 LO = 0.0)
• The TUNING GAIN2 must be equal to (IN1 HI – IN1 LO) / (IN2 HI – IN2 LO).

Output Override
This instrument allows override of the Loop 1 output with the Loop 2 output based upon
which is larger or smaller. This can be accomplished by configuration (See Section 3.8)
or by Digital Input actuation (see Section 3.19).
The following rules apply for high/low override:
•
Only one physical output is required when override is enabled. It is the output
from Loop 1 because Loop 2’s internal output is routed through the selector.
•
Loop 2 output can also be available at all times if desired.
•
In Manual mode, the Output may be overridden.
•
Does not apply for Three Position Step Control.

Introduction
Operation of two individual loops of control is identical to operating a single loop of
control except that TUNING 2 group applies to Loop 2 only and four PID sets, 5 through
8, are available. TUNING group applies to Loop 1 with PID sets 1 through 4 applicable.
Operating modes and setpoint source
The rules for Auto/Manual modes and changing setpoint sources are the same as single
loop operation.
Keyboard operation
Note that the loop being displayed is the only loop affected by normal keyboard
operation. However, either loop can be reconfigured when in the Set Up mode regardless
of which is being displayed during normal operation.
Accutune III
Two independent loops or cascaded loops can be tuned at the same time, if so configured.
Setpoint Ramp or SP Programming
Either loop or both loops can be configured for a single setpoint ramp operation by
enabling the desired loop or loops (see Section 3 – Configuration)
An “H” or “R” will appear in the upper display when applicable, depending upon which
loop is being displayed.
Digital Inputs (remote mode switching)
Digital Input 1 is dedicated to Loop 1 when two loops or Cascade control is configured.
The other digital inputs may be configured to work on either loop.
Output Override Hi/Lo select
Output Override allows you to select the higher of Output 1 and Output 2 (Hi Select) or

4.21 Alarm Setpoints
Introduction
An alarm consists of a relay contact and an operator interface indication.
222
UDC3500 Universal Digital Controller Product Manual
10/05
Monitoring and Operating the Controller
During normal operation, alarm relays in the inactive state (no alarm condition exists)
will have their Normally Open (NO) contacts closed. Alarm relays in the active state
(alarm condition exists) will have their Normally Closed (NC) contacts closed. See Table
2-3 in the Section 2 – Installation for alarm relay contact information. This means that
the alarm relays are designed to operate in a failsafe mode (that is, the relay coil is deenergized – NC contacts are closed – when an alarm is active). If power is lost to the unit,
the alarms will de-energize and thus the alarm contacts will close.
When power is first applied to the instrument, all alarm relays will remain in the deenergized state until the instrument completes its self-diagnostic routine. The alarms
relays will then energize or remain de-energized, depending upon their configuration and
their monitored parameter.
There are eight alarm setpoints, two for each alarm. The type and state (High or Low) is
selected during configuration. See Subsection 3.21 – Configuration for details.

Setpoint Programming Event Alarms
An alarm setpoint can be configured to turn on or turn off an alarm based upon a
particular segment in a Setpoint Program.
Using Alarm 1 Setpoint 1 as an example:
If Alarm 1 Setpoint1 Value (A1S1 VAL) is configured for Segment 5, Alarm 1 Setpoint
1 Type (A1S1TYPE) is configured for Event On (EV ON) and Alarm 1 Segment 1
Event (A1S1 EV) is configured for BEGIN, then this alarm will activate when the
Setpoint Program reaches the beginning of Segment 5.
ATTENTION If no other alarm configuration turns this alarm off after the above
configuration has turned it on, then when the Setpoint Program is configured to be
disabled when the Setpoint Program ends, this alarm will stay on.
If Alarm 1 Setpoint1 Value (A1S1 VAL) is configured for Segment 5, Alarm 1 Setpoint
1 Type (A1S1TYPE) is configured for Event Off (EV OFF) and Alarm 1 Segment 1
Event (A1S1 EV) is configured for END, then this alarm will deactivate when the
Setpoint Program reaches the end of Segment 5.
ATTENTION Some other alarm configuration must first turn the alarm on before this
configuration can turn it off.

4.22 Three Position Step Control Algorithm
Introduction
The Three Position Step Control (TPSC) 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 to move it downscale, without a feedback slidewire linked to the
motor shaft.
Estimated Motor Position
The Three Position Step control algorithm provides an output display, which is an
estimated motor position since there is no slidewire feedback.
• Although this output indication is only accurate to a few percent, it is corrected each
time the controller drives the motor to one of its stops (0 % or 100 %).
• It avoids all the control problems associated with the feedback slidewire (wear, dirt,
and noise).
• When operating in this algorithm, the output display is shown to the nearest percent
(that is, no decimal).
The Motor Travel Time (the time it takes the motor to travel from 0 % to 100 %) must be
configured in order for TPSC to operate correctly. See Section 3.11.

Accurate Motor Position
In the event that an accurate and repeatable indication of motor position is required, the
instrument’s Third Analog Input may be used to read the motor’s slidewire. The Third
Analog Input must be configured for slidewire operation. Motor position is then shown
on the lower display as POS XX.X. The TPSC algorithm does not use this value; it is
only used for display purposes.
The slidewire must be calibrated for this display to operate correctly. See Section 6.5.

4.25 Carbon Potential, Oxygen and Dewpoint Algorithms
Introduction
Carbon probes can be used to control Carbon Potential, Percent Oxygen or Dewpoint
applications by configuring the Input Algorithm 1 for the desired type.
Most carbon probes consist of a zirconium oxide (ZrO2) sensor and a thermocouple (to
measure the temperature at the ZrO2 sensor). These probes generally have four wires, two
for the ZrO2 sensor and two for the thermocouple. The ZrO2 sensor is connected to Input
1 on this controller while the thermocouple is connected to Input 2. Input 1 actuation is
automatically set to Carbon when any Carbon Potential Algorithm is configured, to
Oxygen when the Oxygen Algorithm is configured, and to Carbon when the Dewpoint
Algorithm is configured. The thermocouple in these probes is normally a K, R or S
thermocouple type. However, Input 2 can be configured for any input actuation for
applications where some other temperature sensor is used. PV Source in the Control Set
Up Group should be configured to IN ALG 1.
Instruments with Two Loops may use Loop 1 to control the Carbon/Oxygen/Dewpoint of
the oven while Loop 2 may use the temperature measured by Input 2 to control the
temperature of the oven. For this application, PV Source in the Control Set Up Group
10/05

should be configured to IN ALG 1 while PV Source in the Control 2 Set Up Group

Carbon Potential
The percent Carbon Monoxide (CO) content of the enriching gas may be entered as a
fixed value or Input 3 on the controller may be used to measure CO content as a live
value provided by a separate sensor.
All calculations are performed by the Controller with Percent Carbon shown as the PV
display. The actual reading of each analog input is available for viewing on the lower
display.
The controller computes the atmosphere’s actual carbon potential from these inputs and
compares the computed value with the desired setpoint. An on-off or PID control
algorithm determines the controller output necessary to keep the actual carbon potential
at the setpoint.
228
UDC3500 Universal Digital Controller Product Manual
10/05
Monitoring and Operating the Controller
Usually only one output is used to add more or less enriching gas (typically natural gas)
to the furnace’s base atmosphere, which has a relatively low carbon potential. The
enriching gas then raises the carbon potential to the desired level. There are occasions
when it is desirable to use dilution air in order to lower the carbon potential instead of
enriching gas to raise it. In those instances, a second output from the controller can
provide this function by configuring duplex control. When duplex proportional control is
used, a different set of PID tuning constants is used for the dilution air than those used for
the enriching gas.
Although the temperature used for these Carbon algorithms is normally a live value read
by Input 2, it may also be configured as a fixed value. The fixed value selection is useful
for when an Automotive Sensor is used, as these do not contain a thermocouple sensor.

Dewpoint
The Dewpoint Algorithm is used for controlling the Dewpoint in endothermic
atmospheres. Furnace Control’s Accucarb ZrO2 sensor is used on Input 1. Input 1
actuation is automatically set to Carbon when the Dew Point Algorithm is configured.
Input 2 may be any input actuation, but it is normally a type K, R or S thermocouple
input.
The percent Hydrogen (H2) atmospheric content is entered as a fixed value.
All calculations are performed by the Controller with the Dewpoint temperature shown as
the PV display. The actual reading of each analog input is available for viewing on the
lower display.
The availability of Dewpoint on Input Algorithm 2 provides the capability of controlling
Carbon Potential on Loop 1 while also being able to calculate the Dewpoint value from
the same probe. For this configuration, “DEW XX.X” may be viewed on the lower
display, where “XX.X” is the Dewpoint temperature.
4.26 Healthwatch
Introduction
The Healthwatch feature puts diagnostic data at your fingertips so you can monitor vital
performance status to improve your process, predict failures, and minimize downtime.
Valuable data regarding maintenance and diagnostic selections can be read by operatoraccessed displays. Alarms can be configured to activate when the desired threshold is
reached.
See Section 4.18 Maintenance for details on using the various Healthwatch timers and
counters. See Section 4.15 Alarms for details on Healthwatch maintenance alarms.
4.27 Setpoint Rate/Ramp/Program Overview
Introduction
The Setpoint Ramp configuration group lets you enable and configure any of the
following:
•
SP RATE – a specific rate of change for any local setpoint change. (Subsection 4.28)
•
SP RAMP – a single setpoint ramp that occurs between the current local setpoint and
a final local setpoint over a time interval of 1 to 255 minutes. (Subsection 4.29)
•
SP PROG – a ramp/soak profile in a 20-segment program. (Subsection 4.30)
This section explains the operation of each selection and configuration reference where
necessary.

Monitoring and Operating the Controller
PV Hot Start
This is a standard feature. At power-up, the setpoint is set to the current PV value and the
Rate or Ramp or Program then starts from this value.
RUN/HOLD key
You can start or stop the Ramp or Program using the RUN/HOLD key.
4.28 Setpoint Rate
Introduction
When you have configured a SETPOINT RATE, it will apply immediately to local
setpoint change.
Configuration check
Make sure:
•
SPRATE is enabled
•
A Rate Up (EUHRUP) or Rate Down (EUHRDN) value has been configured in
Engineering units per hour.
ATTENTION
A value of 0 will imply an immediate change in setpoint, that is, NO RATE applies. See
Subsection 3.6 – Configuration group “SPRAMP” for details.)
Operation
When a change to local setpoint is made, this controller will ramp from the original
setpoint to the “target” setpoint at the rate specified.
The current setpoint value is shown as SPn XXXX on the lower display while the
“target” setpoint is shown as SP XXXX on the lower display.
Power outages
If power is lost before the “target” setpoint is reached, upon power recovery, the
controller powers up with Sn = Current PV value and it automatically “Restarts” from Sn
= current PV value up to the original “target” setpoint.
4.29 Setpoint Ramp
Introduction
When you have configured a SETPOINT RAMP, the ramp will occur between the
current local setpoint and a final local setpoint over a time interval of from 1 to 255
minutes. You can RUN or HOLD the ramp at any time.

4.30 Setpoint Ramp/Soak Programming
Introduction
The term “programming” is used here to identify the process for selecting and entering
the individual ramp and soak segment data needed to generate the required setpoint
versus time profile (also called a program).
There are new features in this group that do not appear in previous NGC products:
•
20 segments instead of 12
•
10 Guaranteed Soak Settings (one for each Soak Segment)
•
PID Set selection for each Segment
A segment is a ramp or soak function which together make up a setpoint program.
Setpoint Ramp/Soak Programming lets you configure 10 ramp and 10 soak segments to
be stored for use as one program or several small programs. You designate the beginning
and end segments to determine where the program is to start and stop.
Review program data and configuration
While the procedure for programming is straightforward, and aided by prompts, we
suggest you read “Program Contents”. Table 4-30 lists the program contents and an
explanation of each to aid you in configuration. Then refer to Subsection 3.6–
Configuration to do the setpoint program.
Make sure SPRAMP is disabled.
Fill out the worksheet
Refer to the example in Figure 4-7 and draw a Ramp/Soak Profile on the worksheet
provided (Figure 4-8) and fill in the information for each segment. This will give you a
record of how the program was developed.

Recycle value to 0. The program mode is placed in HOLD.
If the current Local Setpoint 1 value is at any value other than
that Setpoint value used in the first Soak segment in the
program, then the program will restart at the current Local
Setpoint 1 value and at the beginning of the first Ramp
segment in the program.
If the current Local Setpoint 1 value is at the same Setpoint
value as that used for the first Soak segment in the program,
then the first Ramp segment is skipped and the program will
restart at the beginning of the first Soak segment in the

HOTSTART
Hot Start
This function determines whether LSP1 or PV is used as the
setpoint when the program is initially changed from HOLD to
RUN. The selections are:
DISABLE = When the program is initially changed from HOLD
to RUN the present LSP1 value is captured as
the default setpoint. If the program is terminated
or the power cycled before the program has
completed, the LSP1 is used as the control
setpoint. The beginning segment uses this value
as the initial ramp setpoint.
ENABLE = When the program is initially changed from HOLD
to RUN the present PV value is captured and
used as the beginning setpoint value for the ramp
segment. If the program is terminated before
completion, the setpoint value will revert back to
the PV value captured at the initial HOLD to RUN
transition. If the power is cycled before program
completion, upon power-up the setpoint is set to
the PV value at power-up and when the program
is restarted that setpoint value is used initially.
RAMPUNIT
SEGxRAMP or
SEGxRATE
Ramp time or
rate segments
A ramp segment is the time it will take to change the setpoint
to the next setpoint value in the program.
Ramps are odd number segments (1, 3, . . . 19). Segment #1
will be the initial ramp time.
Ramp time is determined in either:
TIME - Hours.Minutes
Range = 0-99hr.59 min.
or
RATE - EU/MIN or EU/HR Range = 0 to 999
This selection of time or rate is made at prompt “RAMPUNIT”.
Set this prompt before entering any Ramp values.
ATTENTION Entering “0” implies an immediate step change
in setpoint to the next soak.
SEGx SP
SEGxTIME
Soak segments
A soak segment is a combination of soak setpoint (value) and
a soak duration (time).
• Soaks are even number segments (2, 4, . . . 20).
• Segment 2 will be the initial soak value and soak time.
• The soak setpoint range value must be within the setpoint
high and low range limits in engineering units.
• Soak time is the duration of the soak and is determined in:
TIME – Hours:Minutes
10/05
Range = 0-99 hr:59 min.

Guaranteed Soak Each individual soak segment can have a unique guaranteed
deviation value of from 0.000 to ±99.99 in engineering units.
Deviation Value
Guaranteed Soak deviation values greater than zero ensure
that the soak segment’s process variable is within the ±
deviation value for the configured soak time. Whenever the ±
deviation value is exceeded, the soak timer stops until the
process variable gets within the ± deviation value. While the
soak timer is halted, “R” and “H” will alternate in the upper
display. When the PV gets within the ± deviation value, the
timer will resume and a steady “R” will appear in the upper
display.
There are no guaranteed soaks whenever the deviation value
is configured to 0.00 (that is, soak segments start timing soak
duration as soon as the soak setpoint is first reached,
regardless of where the process variable remains relative to
the soak segment).
The decimal location used here corresponds decimal
configuration chosen in the Display Set up group.

setpoint program. The program is placed in hold at the beginning. The mode will be as
configured under “PWR UP” in the “CONTROL” group.
Digital Input (remote switch) operation
Program can be placed in RUN, HOLD, RERUN, or BEGIN state through a remote dry
contact connected to optional digital input terminals, as follows:
RUN—contact closure places Program in RUN state, OR
HOLD—contact closure places Program in HOLD state
RERUN—contact closure allows the Setpoint Programmer to be reset to the initial
segment of its current cycle, unit stays in previous mode.
Opening the contact will cause the Controller to revert to its original state.
BEGIN— Contact closure resets the SP Program back to the beginning of the first
segment in the program and puts the program in the HOLD mode. Program cycle number
is not affected. Reopening the switch has no effect.
Opening the contact will cause the Controller to revert to its original state.

Connecting to the Controller via Ethernet Communications
WARNING
Connecting to the Controller via Ethernet Communications requires that you change your PC’s
IP settings. If you have never done this before, then it is strongly recommended that you
consult with your Information Technologies (IT) representative before proceeding.
First, write down the current IP Address, Subnet Mask and Default Gateway settings on
your PC. Put these someplace that you can find them later.
Connecting to the Ethernet Port requires that you have either an Ethernet crossover cable
or a MDI-compliant Switch or Hub available with a straight-through cable. The crossover
cable can be used to directly connect your PC to the controller while the Switch or Hub
can be used to connect your PC and Controller to the Hub or Switch via straight-through
cables.
Once you have made an Ethernet connection between your PC and the controller, then
change the Local Area Network (LAN) settings on your PC to be as follows:
IP Address:
10.0.0.3
Subnet Mask:
255.255.255.0
Default Gateway: 10.0.0.1

5 Input Calibration
WARNING—SHOCK HAZARD
INPUT CALIBRATION MAY REQUIRE ACCESS TO HAZARDOUS LIVE CIRCUITS, AND
SHOULD ONLY BE PERFORMED BY QUALIFIED SERVICE PERSONNEL. MORE THAN
ONE SWITCH MAY BE REQUIRED TO DE-ENERGIZE UNIT BEFORE CALIBRATION.
5.1 Overview
Introduction
This section describes the field calibration procedures for Analog Inputs 1 through 5.
•
All input actuations in every controller are fully factory-calibrated and are ready for
configuration by the user.
•
Field Calibration can improve the accuracy of the Controller if necessary for a
particular application.
CAUTION
The field calibration will be lost if a change in input type configuration is implemented at a later
time. The original factory calibration data remains available for later use after a field calibration
is done. See Section 5.6 if you want to restore factory calibration values.

Calibration Steps
Use the following steps when calibrating an input.
Step
Action
1
Find the minimum and maximum range values for your PV input range from Table 5-1.
2
Disconnect the field wiring and find out what equipment you will need to calibrate.
3
Wire the calibrating device to your controller according to the set up wiring instructions
for your particular input (Subsection 5.4)
4
Follow the calibration procedure given for Input #1 or Input #2 (Subsection 5.5).
5.2 Minimum and Maximum Range Values
Select the Range Values
Calibrate the controller for the minimum (0 %) and maximum (100 %) range values of
your particular input type. Instruments with two or more analog inputs will need to have
each input calibrated separately.
Select the Voltage, Current or Resistance equivalents for 0 % and 100 % range values
from Table 5-1. Use these values when calibrating your controller.

Decade Resistance Boxes are usually not accurate enough to meet the 0.02% accuracy
requirement noted in Table 5-2. This can be overcome by performing a four-wire resistance
measurement with a precision DMM and then adjusting the Decade Box to the correct zero and
span resistance values as given in Table 5-1. Determine the proper zero and span resistance
settings prior to attaching the Decade Box to the instrument. For best accuracy, measure with
the DMM connected to the wire ends rather than directly to the Decade Box.

Table 5-7 Procedure to determine calibration voltages for Thermocouple
Differential input types other than the Factory Setting
Step
Action
1
Obtain a copy of the ITS-90 Standard for the Thermocouple Type you will be using.
2
Find the thermoelectric voltage for the desired operating temperature.
3
Find the thermoelectric voltages for the temperatures –50°F and +150°F away from the
desired operating temperature.
4
The zero calibration voltage will be thermoelectric voltage for the –50°F temperature
minus the thermoelectric voltage for the desired operating temperature. This will be a
negative voltage.
5
The span calibration voltage will be thermoelectric voltage for the +150°F temperature
minus the thermoelectric voltage for the desired operating temperature. This will be a
positive voltage.
For example: Determine the calibration voltage values for a pair of J-type thermocouples
at an operating temperature of 450°F (this is equivalent to the Factory setting).
266
•
The ITS-90 standard for the J thermocouple shows that the thermoelectric
voltage for 450°F is 12.568 millivolts.
•
The –50°F point would be 400°F. The ITS-90 standard shows that the
thermoelectric voltage for 400°F is 11.025 millivolts.
•
The +150°F point would be 600°F. The ITS-90 standard shows that the
thermoelectric voltage for 600°F is 17.188 millivolts.
•
The zero calibration voltage is thus 11.025 minus 12.568 millivolts or –1.543
millivolts (this can be rounded off to –1.54 millivolts without significant loss of
accuracy).
•
The span calibration voltage is thus 17.188 minus 12.568 millivolts or +4.62
millivolts.
•
Use –1.54 millivolts for the Zero calibration value and +4.62 millivolts for the
Span calibration value.

5.6 Restore Input Factory Calibration
Introduction
The factory calibration constants for all the input actuation types that can be used with
the controller are stored in its non-volatile memory. Thus, you can quickly restore the
“Factory Calibration” for a given input actuation type by simply changing the actuation
type to another type and then changing it back to the original type.
Refer to Table 5-13 Restore Factory Calibration for procedure
ATTENTION
A restored factory calibration overwrites any previous field calibration done for the input and
may change the High and Low Range Limits.
Protect your field calibration from accidental overwrites by configuring the appropriate
LOCKOUT selection after calibration.

6.2 First Current Output Calibration
Introduction
Calibrate the controller so that the output provides the proper amount of current over the
desired range. The controller can provide a current output range of from 0 mA to 21 mA.
The controller is usually calibrated at 4 mA for 0 % of output and 20 mA for 100 % of
output, but it may be calibrated for any other values between 0 mA and 21 mA. It is not
necessary to re-calibrate the controller in order to change from 4 to 20 mA operation over
to 0 to 20 mA operation, a simple configuration change is all that is required. See the CO
RANGE configuration for First Current Output in Sub-section 3.11 for details.
Equipment Needed
You will need a standard shop type milliammeter, with whatever accuracy is required,
capable of measuring 0 to 20 milliamps.
Calibrator Connections
Refer to Figure 6-1 and wire the controller according to the procedure given in Table 6-1.

6.3 Second Current Output Calibration
Introduction
Calibrate the controller so that the output provides the proper amount of current over the
desired range. The controller can provide a current output range of from 0 mA to 21 mA.
The controller is usually calibrated at 4 mA for 0 % of output and 20 mA for 100 % of
output, but it may be calibrated for any other values between 0 mA and 21 mA. It is not
necessary to re-calibrate the controller in order to change from 4 to 20 mA operation over
to 0 to 20 mA operation, a simple configuration change is all that is required. See the CO
RANGE configuration for Second Current Output in Sub-section 3.19 for details.
Equipment Needed
You will need a calibrating device with whatever accuracy is required, capable of
measuring 0 to 20 mA.
Calibrator Connections
Refer to Figure 6-2 and wire the controller according to the procedure given in Table 6-3.

6.6 Restore Factory Output Calibration
Introduction
The factory calibration constants for the Current Outputs are stored in its non-volatile
memory. Thus, you can quickly restore the “Factory Calibration” for those outputs by
simply changing the CO RANGE setting for that output to the other setting and then
changing it back to the original type.
Refer to Table 6-8 Restore Factory Calibration for procedure
ATTENTION
A restored factory calibration overwrites any previous field calibration done for the output.
Protect your field calibration from accidental overwrites by configuring the appropriate

Installation related problems
Read the Installation section in this manual to make sure the instrument has been
properly installed. The installation section provides information on protection against
electrical noise, connecting external equipment to the controller, and shielding and
routing external wiring.
ATTENTION System noise induced into the controller will result in diagnostic error
messages recurring. If the diagnostic error messages can be cleared, it indicates a “soft”
failure and is probably noise related.
If system noise is suspected, completely isolate the controller from all field wiring.
Use calibration sources to simulate PV and check all controller functions; i.e. Gain, Rate,
Reset, Output, Alarms, etc.
See Section 11.3 for further information.
Application related problems
Review the application of the controller; then, if necessary, direct your questions to the
local sales office.
Hardware and software related problems
Use the troubleshooting error message prompts and controller failure symptoms to
identify typical failures that may occur in the controller. Follow the troubleshooting
procedures to correct them.
7.2 Troubleshooting Aids
Overall error messages
An error message can occur:
• At power-up. See Subsection 7.3.
• When the Status Tests are requested. See Subsection 7.4.
• During continuous background tests while in normal operation. See Subsection 7.5.

7.3 Power-up Tests
What happens at power-up
When power is applied, the controller will run three diagnostic tests – Memory (RAM),
Calibration and Configuration. After these tests are completed, “TEST DONE” is
displayed.
Failsafe Failures
If one or more of these tests fail, the controller will go to the Failsafe Manual Mode, and
“FAILSAFE” and one or more diagnostic messages will appear in the lower display. See
Section 7.5 – Background Tests and Diagnostic Messages for diagnostic procedures.
Position Proportional and Three Position Step test failures
If Auto-calibration has never been performed on a controller configured for Position
Proportional or Three Position Step Control with motor position indication, then the
diagnostic CAL MTR will appear on the lower display. Refer to Section 6.5 – Position
Proportional and Three Position Step Output Calibration. This error message is cleared
once the slidewire input has been calibrated.

Background Tests and Diagnostic Messages
Introduction
This instrument performs ongoing background tests to verify data and memory integrity.
If there is a malfunction, a diagnostic message will be displayed (blinking) in the lower
display.
In the case of simultaneous malfunctions, the messages will appear in sequence in the
lower display. Table 7-3 lists these background tests in order by their priority, the reason
for their failure, and how to correct the problem.
Diagnostic messages may be suppressed (stop the blinking) by pressing the RUN/HOLD
key. The messages will still be available for viewing by pressing the LOWER DISPLAY
key. If the underlying condition has not been corrected, then the next time the instrument
is powered-down/powered-up, the diagnostic message will return.

7.6.6 Procedure #6 – Alarm Relays
ATTENTION
If the controller is configured to use the same relay for more than one function, then the
following priority is used to determine how the relay functions: Control Outputs take
precedence over Alarms, which in turn take precedence over Time/Events, which in turn
take precedence over Logic Gate Outputs. For example, if you select the Loop 2 Output
Algorithm as Time Simplex (which uses Relay 3), enable Alarm 3 (which also uses
Relay 3) and configure a Logic Gate to use Relay 3, then the instrument will use Relay
#3 to perform the Time Simplex output and ignore the Alarm and Logic Gate functions.
The prompts for the Alarm Outputs appear whether or not the alarm relays are
physically present or used for some other function. This allows the Alarm status to be
shown on the display and/or sent via communications to a host computer.

9.2 General Information
This instrument uses a subset of the standard Modbus RTU function codes to provide
access to process-related information. Several MODICON function codes are
implemented. It is appropriate to define instrument-specific "user-defined" function
codes. Where differences occur between the two protocols it will be noted. Several
standard Modbus RTU function codes are supported.
Configuration ID Tags
Function codes 20 and 21 use the RS422/485 tag IDs for accessing configuration and
process-related data. These tags are fully explained in Section 10.
The tag IDs represent the register addresses used in the Request Message.

General Information
Non-volatile Memory Retention
•
328
This controller uses non-volatile memory to store configuration data. These memories
are guaranteed to retain data for a minimum of ten years as long as the data is not
written and erased more than 10,000 times. In order not to exceed this number, it is
strongly recommended that configurations that change rapidly such as Computer
Setpoint use the Override feature, which does not affect non-volatile memory.
UDC3500 Universal Digital Controller Product Manual
10/05
Modbus Read, Write and Override Parameters plus Exception Codes
Analog Parameters
•
Whenever analog register addresses xx01 through xx7F (those that can be
changed via communications) are changed, a Write cycle occurs after receipt of
the message and the response is returned.
Override Parameters
•
Override analog register address xx7D (computer setpoint) is not stored in nonvolatile memory. It can be changed as frequently as desired with no effect on nonvolatile memory retentivity, but the controller must remain in the slave mode.
Digital Parameters
•
Whenever digital configuration register addresses xx80 through xxFF are updated
via communications, the non-volatile memory is updated as soon as the message
is received.
Communications Transfer Rates
•
Reads minimum 20 milliseconds and writes minimum 200 milliseconds.
Supported Function Codes
•
IR port 20 and 21
•
RS485 and Ethernet ports 1,2,3,4,6,8,16,17,20,21
Communications Modes of Operation
•
When the Shed Timer is enabled and a write or override occurs the controller will
enter Slave Mode. The keypad is locked from the operator. The purpose of this
mode is that if communications is lost and the shed timer times out then the
controller will enter a known state of operation. The configuration of the “Shed
Mode and Output” and Shed Setpoint Recall are used to configure the controller’s
shed state. While in Slave Mode pushing the
key enters Emergency Manual
mode. The local operator then has control of the output. The controller is in
Monitor Mode if the Shed timer is disabled.

10.5 Setpoints
Overview
You can use four separate local setpoints in the controller. The identifying register
addresses listed in Table 10-5 allow you to select which setpoint you want to use and to
enter a value in Engineering Units or Percent (whichever is selected at register address
00A1) for that setpoint via communications.
Register Addresses
Make your selection using register address 00AD and enter the value for the setpoint
chosen using register address in Table 10-5.

10.6 Using a Computer Setpoint (Overriding Controller Setpoint)
Overview
You can use a setpoint generated from the computer to override the setpoint being used
by the controller. The value generated by the computer will have ratio and bias applied
by the controller.
Register Addresses
Use the identifying code in Table 10-7 to enter the computer setpoint.

Shed
The computer setpoint override will continue until SHED from communications occurs
or the controller is placed into monitor mode through communications. Doing periodic
SLAVE READS within the shed time will allow the override to continue until
communication is stopped and shed time elapses. Does not apply to IR communications.
ATTENTION
0 Shed (code 79) allows the override to continue indefinitely or until the reset shed timer
register address 1B90 and 1B91 is written using function code 6 or parameter ID 127
using function code 21. Any data value can be written because it is ignored.
When SP is overridden, the upper display becomes “C” momentarily, and the lower
display shows the CSP value as CSP XXXX.

Modbus Read, Write and Override Parameters plus Exception Codes
10.8 Modbus RTU Exception Codes
Introduction
When a master device sends a query to a slave device it expects a normal response. One
of four possible events can occur from the master’s query:
•
Slave device receives the query without a communication error and can handle the
query normally.
It returns a normal response.
•
Slave does not receive the query due to a communication error.
No response is returned. The master program will eventually process a time-out
condition for the query.
•
Slave receives the query but detects a communication error (parity, LRC or CRC).
No response is returned. The master program will eventually process a time-out
condition for the query.
•
Slave receives the query without a communication error but cannot handle it (i.e.,
request is to a non-existent coil or register).
The slave will return with an exception response informing the master of the nature of
the error (Illegal Data Address.)
The exception response message has two fields that differentiate it from a normal
response:
Function Code Field:
In a normal response, the slave echoes the function code of the original query in the
function code field of the response. All function codes have a most-significant bit
(MSB) of 0 (their values are below 80 hex). In an exception response, the slave sets
the MSB of the function code to 1. This makes the function code value in an
exception response exactly 80 hex higher than the value would be for a normal
response.
With the function code’s MSB set, the master’s application program can recognize
the exception response and can examine the data field for the exception code.
Data Field:
In a normal response, the slave may return data or statistics in the data field. In an
exception response, the slave returns an exception code in the data field. This defines
the slave condition that caused the exception.

01
Illegal Function
The message received is not an allowable action for
the addressed device.
02
Illegal Data Address
The address referenced in the function-dependent data
section of the message is not valid in the addressed
device.
03
Illegal Data Value
The value referenced at the addressed device location
is no within range.
04
Slave Device Failure
The addressed device has not been able to process a
valid message due to a bad device state.
06
Slave Device Busy
The addressed device has ejected a message due to a
busy state. Retry later.
07
NAK,
Negative Acknowledge
The addressed device cannot process the current
message. Issue a PROGRAM POLL to obtain devicedependent error data.
09
Buffer Overflow
The data to be returned for the requested number of
registers is greater than the available buffer space.
