Introduction
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 instruments 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 controllers key. You can now communicate. After 4 minutes, the port will be shut down again. Also, in the Communications Group IR ENABLE may be disabled to prohibit IR communications.

2.4 Control and Alarm Relay Contact Information

Control Relays ATTENTION
Control relays operate in the standard control mode (that is, energized when output state is on).

Alarm Relays 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.

Figure 2-3 Mounting Methods Mounting Procedure Table 2-4 Mounting Procedure
Step 1 2 3 Action Mark and cut out the controller hole in the panel according to the dimension information in Figure 2-2. Orient the case properly and slide it through the panel hole from the front. Remove the mounting kit from the shipping container and install the kit as follows: For normal installation two mounting clips are required. Insert the prongs of the clips into the two holes in the top and bottom center of the case (Figure 2-3). For water-protected installation four mounting clips are required. There are two options of where to install the mounting clips: 1) Insert the prongs of the clips into the two holes on the left and right side of the top and bottom of the case or 2) on the center on each of the four sides (Figure 2-3). Tighten screws to 2 lb-inch (22 Ncm) to secure the case against the panel. CAUTION: Over tightening will cause distortion and the unit may not seal properly.
For water-protected installation, install four screws with washers into the four recessed areas in the corners of the front bezel (Figure 2-3). Push the point of the screw through the center piercing the elastomeric material and then tighten screws to 5 lb-in (56 Ncm).

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 users 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 circuitbreaker 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 2-5.

Installation
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: Separate External WiringSeparate connecting wires into bundles (See Permissible Wiring Bundling - Table 2-5) and route the individual bundles through separate conduit metal trays. Use Suppression DevicesFor 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.
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 (requires auxiliary output); 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 2-6 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, SolidState Relay or Open Collector Output.

Supply
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 450F / 232C.

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 25C and derated linearly to 0.5 Amp at 55C. Customer should size fuse accordingly. Use Fast Blo fuses only. Electromechanical relays are rated at 5 Amps @ 120 Vac or 240 Vac or 30 Vdc. Customer should size fuses accordingly. Use Fast Blo fuses only.

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 3-15 that follow this procedure. 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 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.

3.4 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.
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.
Function Prompts Table 3-4 TUNING Group (Numeric Code 100) Function Prompts
Function Prompt Lower Display English Numeric Code 101 Selection or Range of Setting Upper Display English Numeric Code 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.

I MIN = Reset in Minutes per Repeat I RPM = Reset in Repeats per Minute Integral Time (or Reset) adjusts the controller's output in accordance with both the size of the deviation (SPPV) 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.

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.

3.5 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 12 segments can be configured. For more information on Set Point Rate, Ramp and Programming, see Sections 4.18 through 4.21. 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.

3.6 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. 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: 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: 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. 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 3.11.

3.7 Algorithm Set Up Group

Introduction This data deals with various algorithms in the controller and Timer functions.
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 TREM) or elapsed time (see ET). 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 relayany previous alarm 1 configuration is ignored. At time-out, the timer is ready to be activated again by whatever action has been configured.

The CONTROL ALGORITHM lets you select the type of control that is best for your process. ONOF 0
CTRALG
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 = PVSP). 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: OUTHYS
8/05
45
Configuration
DUPLEX ON/OFF is an extension of this algorithm when the output is configured for Duplex. 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: OUTHYS and DEADBD
PIDA 1
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 controllers output in proportion to the error signal (the difference between Process Variable and Setpoint). Integral (Reset)Regulates the controllers 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 controllers output in proportion to the rate of change of the error. (The amount of corrective action depends on the value of proportional Gain.)
PIDB
PID BUnlike 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.

PDMR
PD WITH MANUAL RESET is used whenever integral action is not wanted for automatic control. The equation is computed with no integral contribution. The MANUAL RESET, which is operator adjustable, is then added to the present output to form the controller output.
Switching between manual and automatic mode will be bumpless. 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.

TPSC 4
THREE POSITION STEP CONTROL (TPSC)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). 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. Calibrate the slidewire.

CURRENT DUPLEX RANGE (SPLIT)This setting should be used for Relay/Current and Current/Relay Duplex Outputs. It can also be used for Current Duplex when an Auxiliary Output board is present. This enables the normal control current output to provide heat control and the auxiliary current output to provide cool control. To enable this:
AUX OUT in the Options Set Up group must be selected for Output. The Auxiliary Current Output is scaled as desired for 0-50 % controller output. Deadband for this configuration only applies to the Current Output. The Auxiliary Output must have the Deadband scaled in. FOR EXAMPLE: 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 Current Output. In the Options group, set the Auxiliary Output LOW VAL selection to 49.0 and the HIGH VAL selection to 0.0.

Introduction
The Communications group lets you configure the controller to be connected to a host computer via Modbus or Ethernet TCP/IP protocol. . Two parameters in this Group, Communications Station Address and TX Delay, are also used for IR communications. No other parameters affect IR communications.
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.

3.14 Alarms Set Up Group

Introduction
An alarm is an indication that an event that you have configured (for exampleProcess Variable) has exceeded one or more alarm limits. There are two 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, High and Low. You can configure each setpoint to alarm either High or Low. These are called single alarms. You can also configure the two setpoints to alarm on the same event and to alarm both high and low. A single adjustable Hysteresis of 0 % to 100 % is configurable for the alarm setpoint. See Table 2-3 in the Installation section for Alarm relay contact information. The prompts for the Alarm Outputs appear whether or not the alarm relays are physically present. This allows the Alarm status to be shown on the display and/or sent via communications to a host computer.

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 the 2nd Local Setpoint or Remote SP regardless of whichever SP is active. 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 pre-determined 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.

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.

4.6 Single Display Functionality

Introduction
This means that the displayed value of PV, Setpoint, Setpoint2, Remote Setpoint, Input 2, Output, Bias, Aux Out, and Deviation will appear on the top display and a prompt identifying the value will appear on the bottom display.
Access the Values
Pressing the LOWER DISPLAY key will cycle through all applicable values (configuration dependent). One minute after the last press of the display key, the display will revert back to a configured default display. The default display is configured in the Input 1 Setup Group, and has three selections:

Active Setpoint (SP) Process Variable (PR Y) Process Variable with no bottom display prompt (PR n).
Exceptions
There are three exceptions to the above rules. The displays for PID SET, Timer and Setpoint Ramp will appear the same as on a dual display model and, when displaying Timer or Ramp values, the default display switchover feature is disabled.
Auto-only Mode
The single display model is Auto only mode. The Auto/Manual key has no effect on controller mode. As a result of this, the failsafe mode is always non-latching. While a failsafe condition exists, the controller output will assume the failsafe value. When the failsafe condition goes away, normal automatic operation continues.

4.8 Control Modes

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.
4.8.1 Mode Definitions

Table 4-7 Control Mode Definitions
Control Mode AUTOMATIC with LOCAL SETPOINT AUTOMATIC with REMOTE SETPOINT (optional) MANUAL (optional) Definition
In automatic local mode, the controller operates from the local setpoints and automatically adjusts the output to maintain the PV at the desired value. In this mode you can adjust the setpoint. See Subsection 4.9 - Setpoints. 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 3.9 or 3.10, Input 1 or Input 2. 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).

4.8.2 What happens when you change modes

Table 4-8 Changing Control Modes (Dual Display Only)
Control Mode Manual to Automatic Local Setpoint Manual or Auto Local to Automatic Remote SP Automatic Remote Setpoint to Manual or Auto Local Setpoint Definition
The Local Setpoint is usually the value previously stored as the Local Setpoint. PV tracking is a configurable feature which modifies this. For this configuration, when the controller is in manual mode, the local setpoint value tracks the process variable value continuously. The Remote Setpoint uses the stored ratio and bias to calculate the control setpoint. If configured for local setpoint tracking, RSP, when the controller transfers out of remote setpoint the last value of the remote setpoint is inserted into the local setpoint. If LSP tracking is not configured, the local setpoint will not be altered when the transfer is made.

4.11 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 3.6 - Accutune Set Up Group for details.
Tuning indicators
TUNE will flash in the upper display until tuning is completed.

Operation
The TUNE (Accutune II) 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 applications, as it reduces any hunt problems for the motor. 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 4.12. 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. The TUNE process will cycle the controllers 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. TUNE flashes in the upper display until tuning is completed.
100
8/05
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 3.11- 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.

4.12 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 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 TUNE (On-Demand) Accutune III tuning algorithm.

4.14 Alarm Setpoints

Introduction
An alarm consists of a relay contact and an operator interface indication. The alarm relay is de-energized if setpoint 1 or setpoint 2 is exceeded. The alarm relay is energized when the monitored value goes into the allowed region by more than the hysteresis. The relay contacts can be wired for normally open (NO) energized or normally closed (NC) de-energized using internal jumper placement. See Table 2-3 in the Section 2 Installation for alarm relay contact information. There are four alarm setpoints, two for each alarm. The type and state (High or Low) is selected during configuration. See Subsection 3.13 Configuration for details.

4.15 Three Position Step Control Algorithm

Introduction
The Three Position Step Control algorithm allows the control of a valve (or other actuator) with an electric motor driven by two controller output relays; one to move the motor upscale, the other 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 (OT) which is an estimated motor position since the motor is not using any 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 estimated OT display is shown to the nearest percent (that is, no decimal). See Motor Travel Time (the time it takes the motor to travel from 0 % to 100 %) in section 3.8.

4.18 Setpoint Rate/Ramp/Program Overview

Introduction
The Setpoint Ramp configuration group lets you enable and configure any of the following:
SPRATE a specific rate of change for any local setpoint change. (Subsection 4.20) SPRAMP 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 4.19) SPPROG a ramp/soak profile in a 12-segment program. (Subsection 4.21)
This section explains the operation of each selection and configuration reference where necessary.
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.
4.19 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.
Configuration Check Make sure SPRAMP is enabled A Ramp Time (TIMIN) in minutes has been configured A final setpoint value (FINLSP) has been configured. See Subsection 3.5 Configuration group SPRAMP for details. Operation
Running a Setpoint Ramp includes starting, holding, viewing the ramp, ending the ramp and disabling it. See Table 4-24.

Power Outage
If power is lost during a ramp, upon power-up the controller will be in HOLD and the setpoint value will be the setpoint value prior to the beginning of the setpoint ramp. The ramp is placed in hold at the beginning. Configure the mode at Set Up Group CONTROL, function prompt PWRUP. See Subsection 3.11 CONTRL GROUP FUNCTION Prompts.
4.20 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 SP RATE and SPPROG are not running. 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 3.5 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 can be viewed at Sn 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.
4.21 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). A segment is a ramp or soak function which together make up a setpoint program. Setpoint Ramp/Soak Programming lets you configure six ramp and six 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 4-25 lists the program contents and an explanation of each to aid you in configuration. Then refer to Subsection 4.21 Configuration to do the setpoint program. Make sure SPRATE and SPRAMP are disabled.
Fill out the worksheet
Refer to the example in Figure 4-3 and draw a Ramp/Soak Profile on the worksheet provided (Figure 4-4) and fill in the information for each segment. This will give you a record of how the program was developed.
Operation
Refer to Table 4-26 Run/Monitor the program.

Program Contents
Table 4-25 lists all the program contents and a description of each.
Table 4-25 Program Contents
Contents Ramp time or rate segments Definition
A ramp segment is the time or rate of change it takes to change the setpoint to the next setpoint value in the program. Ramps are odd number segments. Segment #1 will be the initial ramp time. Ramp time is determined in either: TIME* - Hours:Minutes Range = 0-99 hr.:59 min. or EU-M* - Degrees/Minute Range = 0 to 999 EU-H* - Degrees/Hour *The selection of time or rate is made at prompt RP UNIT - Set this prompt before entering any Ramp information.
114
8/05
Contents
Definition ATTENTION Entering 0 will imply an immediate step change in setpoint to the next soak.
Ramp unit
The ramp unit selection determines the engineering units for the ramp segments. The selections are: TIME = Hours:Minutes (XX:XX) Range: 0-99 hr.:0-59 min EU-H = Degrees/Hour OR EU-M = Degrees/Minute (Range 0-999)
Soak segments
A soak segment is a combination of soak setpoint (value) and a soak duration (time). Soaks are even number segments. 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 Range = 0-99 hr.:59 min.
Start segment number
The start segment number designates the number of the first segment. Range = 1 to 11
End segment number The end segment number designates the number of the last segment, it must be a soak segment (even number). Range = 2 to 12 Recycle number Guaranteed soak
The recycle number allows the program to recycle a specified number of times from beginning to end. Range = 0 to 99 All soak segments can have a deviation value of from 0 to 99 (specified by SOK DEV) which guarantees the value for that segment.
Guaranteed soak deviation values >0 guarantee that the soak segments process variable is within the deviation for the configured soak time. Whenever the deviation is exceeded, soak timing is frozen.
There are no guaranteed soaks whenever the deviation value is configured to 0, (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 soak deviation value is the number in engineering units, above or below the setpoint, outside of which the timer halts. The range is 0 to 99. The decimal location corresponds to input 1 decimal selection.
PV 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:
DISABL = 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.
8/05
115
Contents
Definition ENABL = 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.
Program state
The program state selection determines the program state after completion. The selections are: DIS = program is disabled (so program value changed to DIS) HOLD = program on hold
Program termination state
The program termination state function determines the status of the controller upon completion of the program. The selections are: LAST = controls to last setpoint FSAF = manual mode and failsafe output.
Reset Program to Beginning
When enabled, this selection allows you to reset the program to the beginning from the keyboard. A SP program can be reset to the beginning by using the Display key until "To Begn" appears in the display. If the up (^) arrow is used, the program will go to the beginning (segment 0) and the SetPoint (SP) used at the start the last time the program was RUN. If the program is in RUN, it will go to HOLD when the (^) up arrow is used.
Ramp/soak profile example
Before you perform the actual configuration, we recommend that you draw a Ramp/Soak profile in the space provided on the Program Record Sheet (Figure 4-4) and fill in the associated information. An example of a Ramp-Soak Profile is shown in Figure 4-3. Start setpoint is at 200 degrees F.

5.1 Overview
Introduction
This section describes the field calibration procedures for Input 1 and Input 2.

All input actuations in every UDC2500 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 subsection 0 if you want to restore factory calibration values.

Calibration Steps
Use the following steps when calibrating an input.

Step 1 2 3 4 Action
Find the minimum and maximum range values for your PV input range from Table 5-1. Disconnect the field wiring and find out what equipment you will need to calibrate. Wire the calibrating device to your controller according to the set up wiring instructions for your particular input (Subsection 5.4 or 5.6). Follow the calibration procedure given for Input #1 or Input #2 (Subsection 5.5 or 5.7).
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. Two input controllers 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 and Table 5-2. Use these values when calibrating your controller.

5.8 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 5-14 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. See Section 3 - Configuration for specific instructions to set the lockout.

6.2 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 an output current range of from 0 to 21 milliamperes and is usually calibrated at 4 mA for 0 % of output and 20 mA for 100 % of output, or 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 in Sub-section 3.8 for details.
Equipment Needed
You will need a standard shop type milliammeter, with whatever accuracy is required, capable of measuring 0 to 20 milliamps.

6.3 Auxiliary Output Calibration

Introduction
Calibrate the controller so that the auxiliary output provides the proper amount of current over the desired range. The controller can provide an auxiliary current output range of from 0 mA to 21 mA and is usually calibrated at 4 mA for 0 % of output and 20 mA for 100 % of output or any other values between 0 mA and 21 mA. It is not necessary to recalibrate 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 AO RANGE configuration in Sub-section 3.12 for details.

Installation related problems
Read the Installation section in this manual to make sure the UDC2500 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.
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, which 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.
Controller failure symptoms
Other failures may occur that deal with the Power, Output, or Alarms. Refer to the controller failure symptom in Table 7-4 to determine what is wrong and the troubleshooting procedures to use to correct the problem.

General Information
Non-volatile Memory Retention
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 which change rapidly such as Computer Setpoint use the Override feature which does not affect non-volatile memory.
8/05
173
Analog Parameters
Whenever analog register addresses 0001 through 0074 (those that can be changed via communications) are changed, a Write cycle occurs after receipt of the message and the response is returned. Override analog register address 007D (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. Whenever digital configuration register addresses 0080 through 00FA are updated via communications, the non-volatile memory is updated as soon as the message is received. Reads minimum 20mS and writes minimum 200mS IR port 20 and 21 RS485 and Ethernet ports 1,2,3,4,6,16,17,20,21 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 controllers shed state. While in Slave Mode pushing the MAN/AUTO 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.

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 is written using function code 6 or register address 7F using function code 21. Any data value can be written because it is ignored.
When SP is overridden, the upper display becomes COM momentarily, and the lower display shows the CSP value as CSXXXX.

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 masters 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 codes MSB set, the masters 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.

Query
Example: Internal slave error reading 2 registers starting at address 1820h from slave at slave address 02. 02 03 18 20 00 02 CRC CRC
Response
Example: Return MSB in Function Code byte set with Slave Device Failure (04) in the data field. 02 83 04 CRC CRC
Table 10-21 Modbus RTU Data Layer Status Exception Codes

Exception Code 01 02 Definition Illegal Function Illegal Data Address Description The message received is not an allowable action for the addressed device. The address referenced in the function-dependent data section of the message is not valid in the addressed device. The value referenced at the addressed device location is no within range. The addressed device has not been able to process a valid message due to a bad device state. The addressed device has ejected a message due to a busy state. Retry later. The addressed device cannot process the current message. Issue a PROGRAM POLL to obtain devicedependent error data. The data to be returned for the requested number of registers is greater than the available buffer space. Function Code 20 only.

Ethernet TCP/IP
11 Ethernet TCP/IP
11.1 Overview
Ethernet parameters can only be configured via the Process Instrument Explorer software. Ethernet IP Address is 10.0.0.2 as shipped from the Factory. The MAC address is printed on the case label of each instrument. When constructing a network, it is recommended that a Switch be used to connect UDCs to a LAN rather than using a Hub. This is because a Switch passes only those messages for IP addresses that are connected to the Switch while a Hub passes all message traffic. Using a Switch thus improves the overall throughput of the traffic to and from the UDCs.
