ATTENTION
Alarm relays are designed to operate in a failsafe mode (that is, de-energized during alarm
sate). This results in alarm actuation when power is OFF or when initially applied, until the unit
completes self-diagnostics. If power is lost to the unit, the alarms will de-energize and thus the
alarm contacts will close.

2.5 Wiring
2.5.1 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 1 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.
CAUTION

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
2-4.
Electrical Noise Precautions
Electrical noise is composed of unabated electrical signals which produce undesirable
effects in measurements and control circuits.
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:

04/08

UDC3200 Universal Digital Controller Operator Manual

•

Separate External Wiring—Separate connecting wires into bundles
(See Permissible Wiring Bundling - Table 2-4) 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.

• Input signal wire (thermocouple, 4 to 20 mA, etc.)
• 4-20 mA output signal wiring
Digital input signals
• Low voltage alarm relay output wiring
• Low voltage wiring to solid state type control circuits
• Low voltage wiring to open collector type control circuits

2.6 Wiring Diagrams
Universal Output Functionality and Restrictions
Instruments with multiple outputs can be configured to perform a variety of output
types and alarms. For example, an instrument with a current output and two relays
can be configured to perform any of the following:
1) Current Simplex with two alarm relays;
2) Current Duplex 100% with two alarm relays;
3) Time Simplex with one alarm relay;
4) Time Duplex with no alarm relays; or
5) Three Position Step Control with no alarm relays.
These selections may all be made via the keyboard and by wiring to the appropriate
output terminals; there are no internal jumpers or switches to change. This flexibility
allows a customer to stock a single instrument which is able to handle a variety of
applications.
Table 2-5 shows what control types and alarms are available based upon the installed
outputs. In this table, when Duplex Control and Reverse Action are configured,
“Output 1” is HEAT while “Output 2” is COOL. When Three Position Step Control
is configured, “Output 1” is OPEN while “Output 2” is CLOSE. The Output 1/2
option “Single Relay” can be any of the following selections: Electro-Mechanical
Relay, Solid-State Relay or Open Collector Output.

The 250 ohm resistor for milliamp inputs or the voltage divider for 0-10 Volt 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 applications, the resistor should be located at the
transmitter terminals if Burnout detection is desired.

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 best
accuracy, the two thermocouples should be matched or, preferably, made from the same batch
of wire.

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 millivolt values for the Thermocouple Differential Input are for a pair of J thermocouples at
an ambient temperature mean of 450°F / 232°C.

If the load current is less than the minimum rated value of 20 mA, then there may be residual voltage across both
ends of the load even if the relay is turned off. Use a dummy resistor as shown to counteract this. The total
current through the resistor and the the load must exceed 20 mA. Solid State Relays are zero-crossing type.

Solid State relays are rated at 1 Amp at 25°C and derated linearly to 0.5 Amp at 55°C. Customer should size

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

directions. Stop at the Set Up group title that describes the group of
parameters you want to configure. Then proceed to the next step.
Upper Display = the current value or selection for the first function
prompt of the selected Set Up group.
Lower Display = the first Function prompt within that Set Up group.
Sequentially displays the other function prompts of the Set Up
group you have selected. Stop at the function prompt that you want
to change, then proceed to the next step.

of a parameter while in Set Up mode but then decide not to enter it,
press the MAN/AUTO key once. This will recall the original
configuration. This “recall” procedure does not work for a Field
Calibration process. Field Calibration is a one-way operation.
Enters value or selection made into memory after another key is
pressed.
Exits configuration mode and returns controller to the same state it
was in immediately preceding entry into the Set Up mode. It stores
any changes you have made.
If you do not press any keys for 30 seconds, the controller times out
and reverts to the mode and associated display used prior to entry
into Set Up mode.

GAIN

0.1 to 9999 %
or
0.001 to 1000

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.
G = 100 / %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.

RSET MIN
or
RSET RPM

0.02 to 50.00

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

–100 to +100
(in % output)

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.

that they refer to the cool zone tuning constants on duplex models
or the second set of PID constants, whichever is pertinent.

CONT ALG

Parameter Definition

The CONTROL ALGORITHM lets you select the type of control
that is best for your process.
ON-OFF

ON/OFF is 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 is an extension of this 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 %.
ATTENTION Other prompts affected: OUT HYST and
DEADBAND

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.

PID A is normally used for three-mode control. This means that the
output can be adjusted somewhere between 100 % and 0 %. 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

04/08

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.

3PSTEP

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
“POSITON”.
Refer to the Operation section for motor position displays.
As a customer configurable option, when a second 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
2 actuation to SLIDEW and then calibrate Input 2.

timer is ready to be re-activated by whatever action has been
configured. Alarm 1 is activated at the end of the timeout period.

itself, then select LINEAR.
ATTENTION Prompt only appears when a linear actuation is

FOR EXAMPLE:
If input 1 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 Definition

BURNOUT PROTECTION (SENSOR BREAK) provides most input
types with upscale or downscale protection if the input fails.
NONE

NO BURNOUT—Pre-configured Failsafe output (selected in the
CONTROL Set up Group) applied if failed input is detected (does
not apply for an input out of range). Diagnostic message IN1 FAIL
is intermittently flashed on the lower display.

UPSCALE BURNOUT will force the Input 1 signal to the full scale
value when the sensor fails. Diagnostic message IN1 FAIL
intermittently flashed on the lower display.
The controller remains in Automatic control mode and adjusts the
controller output signal in response to the full scale Input 1 signal
developed by the Burnout circuitry.

DOWN

DOWNSCALE BURNOUT will force the Input 1 signal to the lower
range value when the sensor fails. Diagnostic message IN1 FAIL
intermittently flashed on the lower display.
The controller remains in Automatic control mode and adjusts the
controller output signal in response to the lower range Input 1
signal developed by the Burnout circuitry.

NO FS

NO FAILSAFE— This selection does not provide input failure
detection and should only be used when a thermocouple input is
connected to another instrument which supplies the Burnout
current. (For this selection, no burnout signal is sent to the sensor.)
ATTENTION For Burnout to function properly on a 0-20 mA input
type (or a 0-5V type that uses a dropping resistor), the dropping
resistor must be remotely located (across the transmitter
terminals). Otherwise, the input at the instrument terminals will
always be 0 mA (i.e., within the normal operating range) when the
0-20 mA line is opened.

EMISSIV1

Parameter Definition

NOTE 4. Loop Break monitors the 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 predetermined amount, then the alarm activates, thus signalling 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 “UNITS” setting in the Display Setup Group.
For the Degrees F configuration, the PV must move by 3° in the desired direction in the time allowed. For
the Degrees C configuration, the PV must move by 2° in the desired direction 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.
NOTE 5. Thermocouple Warning means that the instrument has detected that the Thermocouple Input is
starting to fail. Not valid for other input types.
NOTE 6. Thermocouple Failing means that the instrument has detected that the Thermocouple Input is in
imminent danger of failing. Not valid for other input types.
NOTE 7: For the Digital Input selections, DIG INP1 can be either enabled or disabled in the Options

4.2 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.

4.5 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 3.5 - Accutune Set Up Group for
details.

Tuning indicators
A “T” will show in the leftmost alphanumeric of the upper display until tuning is
completed.

04/08

UDC3200 Universal Digital Controller Operator Manual

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.
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 desireable
to enable the FUZZY tune selection. See Section 4.6. 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.

4.5.2 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). 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.

Configuration Check for Duplex
See Subsection 3.5 - Accutune Set Up Group for details.

4.5.4 Using BLENDED TUNE at start-up for Duplex (Heat/Cool)
When DUPLEX has been configured for DISABLE. This is the preferred selection
for Heat/Cool applications which use a highly insulated chamber (a chamber which
will lose heat very slowly unless a cooling device is applied). Only one local setpoint
(LSP 1) is needed for this selection.
This selection results in performance tuning over the full range utilizing both Heat
and Cool outputs to acquire blended tune values that are then applied to both Heat and
Cool tuning parameters. Both PID sets are set to the same values.

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 which
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.
