CHAPTER 1 INTRODUCTION
Introduction
From its surge-resistant power supply to its rugged construction, the 545 process controller is designed to ensure the integrity of your process with maximum reliability — hour after hour, day after day. The isolated inputs and outputs guard against the dangers of electrical interference, the front face meets NEMA 4X standards for watertight operation and exposure to corrosive environments, and the solid metal housing and sturdy rubber keys enhance durability and ESD protection.
The 545 has been engineered to be the industry’s most user–friendly process controller. With three digital display areas — two offering up to 9 characters of true alphanumerics — the 545 effectively eliminates the cryptic messages that could confuse even the most experienced operator. The bright, crisp display is vacuum fluorescent, and offers much better readability than any other display technology. Additional operator–friendly features include: custom programmable alarm messages, illuminated keys, and an easy to use menu system.
The 545 is the most accurate instrument in its class. With a sampling rate of eight times per second, it is ideal for demanding pressure and flow applica­tions. The 545 also offers two universal process inputs and modular, field interchangeable outputs that allow more flexibility than ever before. With two independent full feature control loops, the 545 can take the place of two PID controllers; additionally, preprogrammed functions can be called for cascade, ratio and feed forward applications.
The 545 uses foreground and background loops that facilitate straight forward operator interface in any of the dual loop modes. It also offers sophisticated control algorithms, including heuristic adaptive tuning, split range and duplex outputs (control), and open or closed loop electric actua­tor control (velocity control).
Thank you for selecting the dual loop Process Controller. The 545 is user-configurable for any of the following functions:
• Two independent PID loops
• Single Station Cascade Control
• Single Station Ratio Control
• Feed Forward Control
Specifications and information subject to change without notice.

BASIC OPERATION PROCEDURES
A Quick Explanation of Dual Loop Operation
Upon power up, Loop 1 is in the foreground (displayed), and Loop 2 is in the “background” (hidden). Set up changes only affect the foreground loop; to make changes to the operation of the background loop, it must be brought to the fore­ground.
The controller helps the user identify the foreground and background loops with the following:
When Loop 2 is in foreground DISPLAY key and the PV2 icon are lit
The third display will show a message identifying the foreground loop.
Use the following as a quick guide to key operating functions of your 545. Most of these procedures will affect whichever loop is in the foreground at the time you execute the procedures. Those that are specified by the word GLOBAL will affect both loops (the whole controller).
To switch the foreground and background loops
1. Press FAST+DISPLAY.
To select /change a setpoint
1. Use DISPLAY key to toggle display to Set Point.
2. Use SET PT key to toggle to active setpoint. Before the newly selected setpoint is made active, there is a two-second de-
lay to prevent any disruptive bumps. If the setpoint displayed is ramping, RAMPING will show the 3rd display.
▲▲
3. To change value, press
To change from auto to manual control (bumpless transfer)
1. When in automatic control, press the MANUAL key at any time, except while in the TUNING mode.
2. The MANUAL key will light in red, and the 2nd display will immediately change to indicate current output level.
To change from manual to auto
1. When in manual control, press MANUAL at any time except while in the TUNING or SET UP mode.
2. The 2nd display will not change, and the MANUAL key will no longer be lit once control changes.
To change manual output values
1. Make sure the controller is under manual control.
2. Use the DISPLAY key to toggle 2nd display to output level.
▲▲
3. Use the
or

4. If code is incorrect, INCORRECT appears in the 3rd display. INCORRECT will disappear after two seconds, and a new security code can then be en­tered.
5. The controller will revert back to full security lock after one minute of key in­activity.
To display control output value
1. Toggle DISPLAY key until the 2nd display shows OUT followed by the out- put percentage. This value is the PID output.
In duplex applications, this value does not directly refer to the output
signal (refer to the Chapter 7 section on Duplex Control for details.)
For on/off outputs, the output value shown is either ON or OFF.
For duplex applications with two on/off outputs, the OUT tag is not shown.
In this case, the status of both outputs is shown in the following manner: 1:ON 2:OFF (1 and 2 are the respective outputs).
To display the active PID set
1. Select the desired foreground loop (hold FAST, press DISPLAY).
2. Press MENU to reach Tuning Mode.
3. In TUNING Mode, press MENU to reach the correct Menu parameter.
4. The active PID set will have an asterisk (*) on both sides of the value.
NOTE:
All alarms are software alarms unless tied to an output relay in the SET UP mode. See Chapter 5 and Chapter 7 for more details on alarms.
ALARM OPERATION
Alarms may be used in systems to provide warnings of unsafe conditions. All 545 operators must know how the alarms are configured, the consequences of acknowledging an alarm, and how to react to alarm conditions.
Alarm Indication
Depending on how the system is configured, the 545 indicates an alarm condition(s) for the foreground loop by:
Lit icons ALM 1 and/or ALM 2
Lit ACK key
Displayed alarm message
The 545 indicates an alarm condition(s) for the background loop by:
• Showing the (user defined) message for one or both alarms in the third display
(alternate displays for simultaneous alarms).
To acknowledge an alarm(s):
An acknowledgeable alarm has both a lit icon and a lit ACK key. A non-acknowledgeable alarm has only a lit icon. Figure 2.2 demonstrates acknowledging an alarm.
1. If the alarm is in the background, bring that loop forward using FAST+DISPLAY.
2. To acknowledge Alarm 1, press ACK once.
3. To acknowledge Alarm 2, press ACK twice.
4. If both alarms are activated, press ACK once to acknowledge Alarm 1, then again to acknowledge Alarm 2.
5. The message and alarm icon disappear.

Latching Alarms
If an alarm is set up to be latching (for details, see Chapter 5) then, in general, it must be acknowledged in order to clear the alarm and release the relay (if applicable). A non-latching alarm will clear itself as soon as the process leaves the alarm condition.
Limit Sequence
An alarm can be configured to be both latching and non-acknowledgeable. In this case, the alarm is acknowledgeable only after the process has left the alarm condition. This is similar to the function of a limit controller.
More on Alarms
For more details on how to set up alarms and for examples of various ways alarms can be set up, refer to the section on Alarms in Chapter 7.
NOTE: Powering down the 545 acknowledges/
clears all latched alarms. When powering up, all alarms will be reinitialized.

The enclosure into which the 545 Controller is mounted must be grounded.
WARNING!
Avoid electrical shock. Do not connect AC power wiring at the source distribution panel until all wiring connections are complete.
6. Insert the four mounting collar screws from the rear of the collar. Gradu­ally tighten the screws (using a Phillips #2 screwdriver) to secure the controller against the panel.
7. If there is difficulty with any of the mounting requirements, apply a bead of caulk or silicone sealant behind the panel around the perimeter of the case.
WIRING
Our 545 controllers are thoroughly tested, calibrated and “burned in” at the fac­tory, so the controller is ready to install. Before beginning, read this chapter thor­oughly and take great care in planning a system. A properly designed system can help prevent problems such as electrical noise disturbances and danger­ous extreme conditions.
1. For improved electrical noise immunity, install the 545 as far away as pos­sible from motors, relays and other similar noise generators.
2. Do not run low power (sensor input) lines in the same bundle as AC power lines. Grouping these lines in the same bundle can create electrical noise interference.
3. All wiring and fusing should conform to the National Electric Code and to any locally applicable codes.
4. An excellent resource about good wiring practices is the IEEE Standard No. 518-1982 and is available from IEEE, Inc., 345 East 47th Street, New York, NY 10017, (212) 705-7900.
Diagrams on the next three pages serve as guides for wiring different types of process inputs. The shaded areas on the diagrams show which rear terminals are used for that type of wiring.
Figure 3.3 Terminal Assignments Actual 545 device only has top and bottom numbers of each column of terminals marked.
WARNING!
Electric Shock Hazard! Terminals 1 and 2 carry live power. DO NOT touch these terminals when power is on.
WARNING!
Terminal 9 must be grounded to avoid potential shock hazard, and reduced noise immunity to your system.

OUTPUT MODULES
The 545 output modules are used for control, alarms and retransmission. The four output module types are: Mechanical Relay, Solid State Relay (Triac), DC Logic (SSR Drive) and Analog (Milliamp).
To install these modules, plug them into any of the four output sockets on the printed circuit boards (refer to Chapter 4). The wiring is the same whether the modules are used for control, alarm or retransmission.
The diagrams on the next two pages are a guide for properly connecting the various outputs. To find out which module(s) have been installed in the control­ler, compare the product number on the controller label with the section Order Code in Chapter 1. This section also includes a diagram of how to wire a posi­tion proportioning output, a special application using two mechanical or two solid state relays.
1. Mechanical Relay Output
Output 1 is always Control 1.
Outputs 1, 2 and 3 are jumper selectable for normally open and nor­mally closed on the power supply circuit board.
Output 4 is always configured for normally open and has reduced voltage and current ratings (see Specifications).

Serial Communications
A twisted shielded pair of wires should be used to interconnect the host and field units. Belden #9414 foil shield or #8441 braid shield 22-gauge wire are acceptable for most applications. The foil shielded wire has superior noise rejection characteristics. The braid shielded wire has more flexibility. The maximum recommended length of the RS 485 line is 4000 feet. Termination resistors are required at the host and the last device on the line. Some RS 485 cards/converters already have a terminating resistor. We recommend using RS-232/RS-485 converter (Product #500-485). The communication protocol is asynchronous bidirectional half-duplex, hence the leads are labelled

HARDWARE INPUT TYPES
The Process Variable
The 545 accepts several different types of process variable signals. Set a jumper location to specify the type of input signal. Set the signal range in the software (see Chapter 5 for software menus, or Chapter 7 for applications).
The jumpers for the process variable are located on the Microcontroller Circuit Board (see Figure 4.2). The factory default is Milliamp. Locations are marked as follows:
V Voltage MA Milliamp TC Thermocouple with downscale burnout TC Thermocouple with upscale burnout RTD RTD
Figure 4.1 Location of Printed Circuit Boards for Hardware Configuration
NOTE:
Thermocouple downscale and upscale burnout offers a choice in which direction the controller would react in the event of thermocouple failure. For example, in heat applications, typically, it is desirable to fail upscale (TC ) so that the system does not apply more heat.

NOTE:
Changing the jumpers means moving the jumper connector. The jumper connector slips over the pins, straddling two rows of pins. The printed circuit boards are labeled next to the jumpers.

The Remote Setpoint
Figure 4.2 shows the location of the remote setpoint jumper. The factory de­fault is milliamp. Choose from the following settings:
V Remote setpoint with voltage signal (jumper removed)
mA Remote setpoint with milliamp signal (jumper installed)
Mechanical Relays
There are three output module sockets on the Power Supply Circuit Board, and one output module on the Option Board (see Figure 4.2). The mechanical relay on the Power Supply Board may be configured for either normally open (NO) or normally closed (NC). A jumper located next to each socket determines this con­figuration. All relay output are factory set to NO (normally open).

TUNING
OVERVIEW
The self tune function of the 545 consists of two distinct components — Pretune and Adaptive Tune. In addition, you may choose from three type of Pretune:
TYPE 1 - for slow thermal processes. TYPE 2 - for fast fluid or pressure processes. TYPE 3 - for level control applications.
Choose the type of Pretune in the SELF TUNE menu.
Pretune and Adaptive Tune may be used separately or together. Refer to Chapter 7 for more information.
Each control loop has its own set of TUNING parameters.
On the following pages is the step by step guide to the tuning parameters.

Conclusion/Problem
PRETUNE has generated initial PID and the Dead Time values.
PRETUNE has generated initial PID, Response Time, Noise Band and the Dead Time values.
User has aborted PRETUNE before completion. The Process Variable went beyond the HI LIMIT or LOW
LIMIT. The Process Variable went beyond the HI LIMIT or LOW
LIMIT. The initial Process Variable was near or beyond the HI
LIMIT or LOW LIMIT. TIMEOUT limit was reached before PRETUNE completed.
Too much PV noise was detected.
PV or Cold Junction break detected during PRETUNE.
PV HIGH or PV LOW detected during PRETUNE. SLIDEWIRE break detected during PRETUNE. REMOTE SP break detected during PRETUNE. The initial control output is outside the high and low limits
defined in the Control Menu. The PV moved too quickly to be Analyzed. One or more model parameters are calculated to be zero. The initial PV is too close to the TUNE PT.
The Process Variable went beyond the HI LIMIT or LOW LIMIT.
Corrective Action
Change the HI LIMIT and LOW LIMIT, or the HIGH OUT and LOW OUT, and run PRETUNE again.
Change the HI LIMIT and LOW LIMIT, or the OUT.STEP size, and run PRETUNE again.
Change the manual output percentage, or the HI LIMIT and LOW LIMIT, and run PRETUNE again.
Set a longer TIMEOUT period and/or increase the OUT.STEP size, and run PRETUNE again.
Eliminate the noise source (if possible) or increase the OUT.STEP and run PRETUNE again.
Check the described conditions and make corrections or repairs.
Change the manual output percent and run PRETUNE again.
Increase the OUT.STEP size and run PRETUNE again. Increase the OUT.STEP size and run PRETUNE again. Move Tune PT. (or the set point if TUNE PT. is automatic)
farther from the process variable and run PRETUNE again. Check if any PID values are generated and if they are
acceptable. If not, eliminate noise sources (if possible) and run PRETUNE again.
If Pretune and Adaptive Tune do not generate optimal PID values for control, check the following menu entries:
Message
RESPONSE TIME
NOISE BAND
PRETUNE
Potential Problem
Adaptive Tune cannot run if RESPONSE TIME is inaccurate
Adaptive Tune cannot compensate for PV oscillation due to hysteresis of output device (e.g., a sticky valve).
Pretune does not develop optimum PID parameters.
70 Chapter 6 545 User's Manual
Corrective Action
Run TYPE 2 or TYPE 3 Pretune to obtain the correct value, or enter it manually.
Set NOISE BAND large enough to prevent Adaptive Tune from acting on the oscillation. If oscillation is not acceptable, consider replacing valve.
Wrong Pretune TYPE selected. Refer to Chapter 7, the Section on Self Tune.

A. CONTROL TYPE
Each of the control loops in the 545 can be independently configured.
Software Configuration
1. Go to the CONTROL menu.
2. For the parameter ALGORITHM, select the type of 545 control:
ON-OFF
“Crude” control similar to a household thermostat. Used primarily on slow, stable processes where moderate deviation (cycling) around setpoint is tolerable. Only available with SSR, SSR Drive, and relay outputs.
•P
Proportional only control. Provides much better control than on/off. Used on processes that are less stable or require tighter control, but have few load variations and do not require a wide range of setpoints.
•PI
Proportional plus integral control. In addition to proportional control, it compensates for control errors due to a wide range of setpoints or load requirements. The integral term works to eliminate offsets.
•PD
Proportional plus derivative control. In addition to proportional con­trol, it compensates for control errors due to fast load variations.
•PID
Proportional plus integral plus derivative control. In addition to pro­portional control, it compensates for changes in setpoint, load re­quirements and process variations.
PID/ON-OFF
Only available with Duplex control. First output uses the PID algo­rithm, while second output uses on/off control.

3. For algorithms using the derivative function (D), choose the conditions for the derivative term:
Scroll to parameter D. SOURCE
For derivative action based on error, or deviation from setpoint, choose DEVIATION
For derivative action based on PV changes, choose PV.
B. ALARMS
Each loop of the 545 controller has two extremely flexible and powerful software alarms (4 alarms total). The number of available outputs limits how alarms are linked to relays. A Global Alarm feature allows all alarms to be assigned to the same relay.
The 545 indicates an alarm condition(s) for the foreground loop by:
Lit icons ALM 1 and/or ALM 2
Lit ACK key
Displayed alarm message
The 545 indicates an alarm condition(s) for the background loop by:
• Showing the (user defined) message for one or both alarms in the third dis­play (alternate displays for simultaneous alarms).
NOTE:
The ability to base alarms on parameters other than PV greatly expands the alarm capacity.
Software Configuration
1. Access the ALARM menu.
2. Set values for the following parameters. All possible values are shown.
Remember: there are 2 alarms for each loop (use FAST+DISPLAY to switch loops).
ALM.TYPE:1 and ALM. TYPE:2
Specifies the type of alarm to implement. Selection includes:
HIGH ALARM
High process variable alarm. Occurs when the process variable ex­ceeds the alarm setpoint.
LOW ALARM
Low process variable alarm. Occurs when the process variable goes below the alarm setpoint.
HIGH/LOW
Combination of high and low alarms. Occurs when the PV exceeds the individually set high or low setpoint.
BAND
Creates a band centered around the control setpoint, that is twice the alarm setpoint. Alarm occurs when the process variable travels outside of this band. The alarm is dependent on the control setpoint. As the control setpoint changes, the band adjusts accordingly.
For example, if the control setpoint is 500 and the alarm setpoint is 25, then the band extends from 475 to 525.
DEVIATION
Similar to the band alarm but creates a band only on one side of the control setpoint. Alarm occurs when the process variable deviates from the control setpoint by an amount greater than the alarm set­point. This alarm is dependent on the control setpoint; as the control
72 Chapter 7 545 User's Manual
setpoint changes, the alarm point changes. For example, if the control setpoint is 500 and the alarm setpoint is
+50, then an alarm occurs when the process variable exceeds 550. In order for an alarm to occur when the process variable drops below 450, select an alarm setpoint of –50.
MANUAL
Alarm occurs when the controller is put into manual mode of opera­tion. This may be useful for security purposes or to alert the operator that 545 is no longer under automatic control.
RATE
Alarm occurs when the process variable changes at a rate greater than what is specified by the alarm setpoint and time base. This alarm helps to anticipate problems before the process variable can reach an undesirable level.
For example, if the alarm setpoint is 10 with a time base of 5 seconds, an alarm occurs whenever a change in process variable greater than 10 occurs in 5 seconds.
ALM.SRC.:1 and ALM.SRC.:2
For HIGH , LOW or HIGH/LOW alarms, specifies the variable (source) upon which a selected alarm is based. Selection includes:
•PV
PV2
•SP
RAMP SP
DEVIATION
OUTPUT
ALARM SP:1 and ALARM SP:2
Defines the point at which an alarm occurs. For a RATE (rate of change) alarm, it specifies the amount of change (per RATE TIME period) that must occur before the alarm activates. A negative value specifies a nega­tive rate-of-change. Does not apply to HIGH/LOW alarms.
HIGH SP:1 and HIGH SP:2
For a HIGH/LOW alarm, defines the high setpoint at which an alarm oc­curs.
LOW SP:1 and LOW SP:2
For a HIGH/LOW alarm, defines the low setpoint at which an alarm oc­curs.
DEADBAND:1 and DEADBAND:2
Specifies the range through which the process variable must travel be­fore leaving an alarm condition (see alarm examples at the end of this section). Prevents frequent alarm oscillation or “chattering” if the process variable has stabilized around the alarm point.
ALM.1 OUT and ALM.2 OUT
For any enabled alarm, selects the output number to which the selected alarm will be assigned. It is possible to assign both alarms to the same output relay, thus creating a “global” alarm .

NOTE:
Each of the two loops has two alarms.
LATCHING:1 and LATCHING:2
A latching (YES) alarm will remain active after leaving the alarm condi­tion unless it is acknowledged. A non-latching (NO) alarm will return to the non-alarm state when leaving the alarm condition without being ac­knowledged.
ACK.:1 and ACK.:2
For any enabled alarm, enables or disables operator use of the ACK key to acknowledge an alarm at any time, even if the control process is still in the alarm condition.
A latching alarm can always be acknowledged when it is out of the alarm condition. When either alarm is available to be acknowledged, the ACK key will be illuminated. If both alarms are acknowledgeable, pressing ACK will first acknowledge alarm #1. Pressing ACK a second time will acknowl- edge alarm #2.
POWER UP:1 and POWER UP:2
For any enabled alarm, selects the alarm condition upon power up. Choices are:
NORMAL
Controller will power up in alarm only if it is in alarm condition.
ALARM:
Controller always powers up in alarm regardless of system’s alarm condition. This is an excellent way to activate an alarm if there has been a power failure.
DELAYED
Controller will never power up in alarm, regardless of system’s alarm condition. The system must leave and reenter the alarm condition before the alarm will activate. This is typically used to avoid alarms during start up.
MESSAGE:1 and MESSAGE:2
Allows user to specify a nine-character message to be displayed when the respective alarm is active. If both alarms are active or any other diag­nostic message is present, the messages will alternate.
FAULT
Activates an alarm if the process variable signal is lost. Assign this func­tion to either Alarm 1 or Alarm 2 (not both). This action is in addition the selected alarm type (additive alarm function).
OUTPUT
For a RATE alarm, selects the output action. Use to obtain early indica­tion of a possible break in the process variable signal. Select PV BREAK to have rate-of-change alarm take the same action as a detection of a break in the process variable signal (where it trips to manual control at a predetermined output).
RATE TIME
For RATE alarms, defines the time period over which a discrete change in process variable must occur for the rate alarm to be activated. The amount of change is defined by the alarm setpoint. The rate-of-change is defined as the amount of change divided by the time period.
74 Chapter 7 545 User's Manual
Example A. If the alarm setpoint is set to 10 and the time base is set to 1
second, the rate of change is 10 units per second.
B. If the alarm setpoint is set to 100 and the time base set to 10, the
rate of change is also 10 units per second.
In example A, the process variable would only have to experience a ten unit change over a short period of time, while in Example B, it would require a 100 unit change over a ten second period. Example A is much more sensitive than Example B. In general, for a given rate­of-change, the shorter the time period, the more sensitive the rate

The Duplex control algorithm enables two discrete control outputs for the control loop. Duplex control is commonly used for applications that require both heating and cooling or when 2 control elements are needed to achieve the desired result.
Hardware Configuration
The controller must have two output modules assigned to the loop (any combination of output modules).
Software Configuration
1. Go to the CONFIG. menu. Set LOOP1 OUT or LOOP2 OUT. to DUPLEX.
2. To use different algorithms for each output (PID for the first, and On/Off for the second):
Go to the CONTROL menu. Set ALGORITHM to PID:ON/OFF.
3. To make the control action for each output independent of the other: Go to the CONTROL menu. Set ACTION:1 or ACTION:2 to either DIRECT or REVERSE action based
on the diagrams in the output examples section (Figures 7.2 through 7.8).
4. Go to the TUNING menu. Set values for PID OFST:1 (or ON OFST:1) and PID OFST:2
(or ON OFST:2). These parameters allow the user to independently offset the point at which output 1 and output 2 become active. PID OFSET units are in percent (%) of control output; ON OFST is in engineering units. The settings can be used to make sure there is a dead band, i.e., no controller output around setpoint. They can also be used to overlap output 1 and out­put 2 so that both are “on” in a small band around setpoint.
5. Set MAN. RESET (manual reset) term to 50%. This causes the PID output to be 50% when there is zero error. This term is still active as a “load line” setting when using automatic reset (integral), so set it to 50% whether using automatic reset or not.
6. REL. GAIN (relative gain) changes the gain of Output 2 relative to Output 1. Note that the relative gain can limit the maximum output available for Out­put 2 when using PID control.
7. Go to the CONTROL menu. Set LOW OUT. and HIGH OUT. to limit the maximum or minimum outputs
from Output 1 and Output 2. The actual limitation on the outputs is depen­dent on the offset settings, the relative gain setting and the control action.
76 Chapter 7 545 User's Manual
Duplex Output State Examples
The following Duplex examples represent a variety of ways this function can be set up. PID control examples show the PID output percentage on the horizontal axis, and On/Off control examples show the process variable on the horizontal axis. The vertical axes are the output of each physical output. Most of these examples use the first output as heating and the second output as cooling.
When using PID control, the 545 controller actually displays the PID output. To relate this output to the actual physical output, locate the PID output on the horizontal axis. Draw a vertical line at that point. At the intersection of this vertical
line and the respective output line, draw a horizontal line. The physical output is the value where this horizontal line intersects the respective axis.
The illustrations assume a manual reset/load line term of 50%. Therefore, at zero error (process variable equals setpoint) the PID output is 50%.

Duplex with a overlapping outputs and output limits
A reverse acting output 1 and a direct acting output 2 with: a negative offset for output 1, a positive offset for output 2, and restrictive high and low output limits with PID control.
This combination of offsets results in an overlap where both outputs are active simultaneously when the PID output is around 50%.
The output limits are applied directly to the PID output. This in turn limits the actual output values. In this example, the high output maximum limits the maximum value for output 1, while the low output minimum limits the maximum value for output 2. The value the actual outputs are limited to depends on offset settings, control action and relative gain setting with PID control.

D. SLIDEWIRE POSITION PROPORTIONING CONTROL
Slidewire position proportioning utilizes a slidewire feedback signal to determine the actual position of the actuator being controlled. This option is only
available for one of the two control loops.
Hardware Configuration
The controller must have the Slidewire Feedback option installed. Refer to the order code in Chapter 1 for more information.
The controller must have mechanical relays, solid state relays or DC logic modules installed in the two output sockets corresponding to one control loop (1 or 2).
The Slidewire does NOT have to be wired to the controller in order to set up position proportioning.
Software Configuration
1. To configure the controller before wiring the slidewire feedback signal to the controller, complete these steps:
a. Go to the CONTROL menu. b. Set a value for PV BREAK c. Go to the SPECIAL menu. d. Set a value for DES. OUTPT. e. Set a value for PWR.UP:OUT. f. Go to SER. COMM. menu. g. Set a value for SHED OUT.
2. Place the controller under manual control.
3. Go to the CONFIG. menu.
4. Set either LOOP1 OUT or LOOP2 OUT to POS. PROP (position proportion­ing).
5. Set SLIDEWIRE to LOOP1 or LOOP2.
6. Go to the CONTROL menu.
7. For S/W RANGE, specify the full range resistance of the slidewire from end­to-end. With a 100 ohm slidewire, this parameter should be set to 100.
8. Scroll to OPEN F/B (Open feedback). Enter the ohm value when the actuator is fully open (0 to 1050 ohms).
9. Scroll to CLOSE F/B (Closed feedback). Enter the ohm value when the actuator is fully closed (0 to 1050 ohms).
10. Measure the actual slidewire value at the terminals (10 and 11). As an alternative, set up these two parameters dynamically. Before entering
Set Up set the manual output at 100%. Enter Set Up and change the OPEN F/B value until the actuator just reaches its full open position.
Exit Set Up and set the manual output to 0%. Enter configuration and change the CLOSE F/B value until the actuator just reaches its full closed position.
11. Set the parameter P. PROP. D.B., which is used to eliminate cycling of the motor. A low deadband setting may result in motor overspin or cycling. A high deadband will result in reduction of sensitivity. To set:
a. Go to the TUNING menu. b. Set P. PROP. D.B. to .5%. c. Place controller under Manual control.
CAUTION!
The relay in socket 1 drives the motor counterclockwise and the relay in output socket 2 drives the motor clockwise.
This is important for:
• Wiring the outputs
• Selecting the control ACTION:1 parameter, or
• Determining the normally open or normally closed relays.
The configuration choices influence the way the position proportioning algorithm works.
NOTE: OPEN F/B and CLOSE F/B values are always reference to the CCW end of the Slidewire.
NOTE: P.PROP.D.B. can only be configured if the Slidewire Feedback is wired to the controller.
545 User's Manual Chapter 7 81
Applications
NOTE: Adaptive tuning is not available
with velocity position proportioning control.
d. Change the output percentage and observe if the valve stabilizes at
the new value.
e. If the valve oscillates, increase the P.PROP.D.B. value by 0.5%; re-
peat until oscillation stops.
E. VELOCITY POSITION PROPORTIONING CONTROL
Velocity position proportioning does not utilize direct feedback. It estimates the position of the actuator, based on time and the speed of the actuator.
In automatic control mode, the controller will display “CW” to refer to energizing of the clockwise relay, and “CCW” to refer to energizing of the counterclockwise relay. A blank display means that both relays are de-energized.
In manual control mode, the display is blank unless an output change is being
▲▲
made. Use the while the keys are being pressed. The display indicates the percentage change in valve position in real time. The rate of change is dependent on the values entered for CCW TIME and CW TIME.
The controller will transfer to manual control due to a lost process variable (PV. BREAK), a digital input closure (DES.OUTPT.), a power-up sequence (PWR.UP:OUT.), or lost communications (SHED OUT). In these cases, the output can be set to: remain at its last value with both relays de-energized (OUTS OFF); rotate fully counterclockwise (CCW); or rotate fully clockwise (CW). CCW and CW will energize the respective relay for a period two times that of the CCW TIME or CW TIME.

Hardware Configuration
The controller must have mechanical relay, solid state relay or DC logic modules installed in the first two output sockets.
Refer to the section on Chapter 1 for more information.
Software Configuration
1. Go to CONFIG. menu. Set LOOP1 OUT or LOOP2 OUT to POS. PROP.
2. Go to the CONTROL menu. Set SLIDEWIRE to NONE. Alternatively, set SLIDEWIRE to LOOP1 or
LOOP2, whichever does NOT have velocity position proporioning on it.
3. Set CCW TIME to the amount of time (in seconds) it takes for the actuator to fully rotate in the counterclockwise direction.
Set CW TIME to the amount of time (in seconds) it takes for the actuator to fully rotate in the clockwise direction.
Loads on the valve may affect the time required, therefore, it is best to measure these values when the valve is in service. As an alternative, enter the values specified by the actuator manufacturer and then make adjustments later.
4. Set MIN. TIME to the minimum amount of time the controller must specify for the motor to be on before it takes any action.
5. Set values for PV. BREAK, DES. OUTPT., PWR.UP:OUT. and SHED OUT.

F. STAGED OUTPUTS
t
With staged outputs, one analog output can vary its signal (e.g., 4-20 mA) over a portion of the PID output range. The second analog output then varies its signal over another portion of the PID output range. This is an excellent method to stage two control valves or two pumps using standard control signal ranges.

2. Go to the CONTROL menu.
3. For OUT1 STOP, specify where the first output reaches 100%.
4. For OUT2 START, specify where the second output begins.
G. RETRANSMISSION
The retransmission feature may be used to transmit a milliamp signal corresponding to any of the following values: PV, SP1, Ramp SP1, Out L1, PV2, SP2, Ramp SP2, OUTL2. A common application is to use it to record one of these variables with a recorder.
Hardware Configuration
There must be an analog module installed in output socket 2, 3 or 4.
Software Configuration
Up to two outputs can be configured for retransmission. The menu will scroll through the configuration parameters for specified value “X” (2, 3 or 4).
1. Go to the CONFIG. menu.
2. For OUTPUT:2, OUTPUT:3 and OUTPUT:4 parameters, set one or two of them to RETRANS.
3. Go to the RETRANS. menu.
4. Set the corresponding parameter, TYPE:X, for the first retransmission out­put to define what is being transmitted: the process variable, setpoint, ramping setpoint or output.
NOTE: For an analog output module for
retransmission that was not factory­installed, calibrate the output for maximum accuracy. Refer to Appendix 4 for details on calibration.
545 User's Manual Chapter 7 83
Applications
5. Set parameters LOW RANGE:X and HIGH RANGE:X for the first retrans­mission output, to define the range of the transmitted signal in engineering units. This can be useful in matching the input range of the receiving device.
6. For any other retransmission output, continue to scroll through the this menu and set the TYPE:X, LOW RANGE:X and HIGH RANGE:X for the second retransmission output.
H. DIGITAL INPUTS
Digital inputs can be activated in three ways: A switch (signal type)—the rec­ommended type, a relay, or and open collector transistor
Digital inputs are only functional when that option is installed (via hardware). The controller detects the hardware type, and supplies the appropriate software menus (see the section on parameters in Chapter 5). There are 14 contact types for the five digital inputs.
Hardware Configuration
This optional feature is only available if ordered originally from the factory, Product #545xxxxxxDx00. The five digital inputs share a common ground.
NOTE: To take advantage of multiple setpoints, make sure that the SP NUMBER parameter in the SPECIAL menu is set to a value greater than 1.

Basic Operating Procedures
1. If more than one digital input closes and their actions conflict, the last digital input that closed has priority.
For example, if one digital input closes and selects 2nd setpoint, and then another digital input closes and selects a remote setpoint, the remote setpoint takes precedence.
2. Any digital input can be overridden by: another digital input, a keyboard operation, or an automatic function. If a closed digital input is overridden, then it must be opened in order to be rearmed.
For example, if one digital input closes and selects the 2nd setpoint, and then a different setpoint is selected through the keyboard, the keyboard selection takes precedence.
545 User's Manual Chapter 7 87
Applications
NOTE: There is a one-second delay
before a closed digital input takes action.
I. REMOTE SETPOINT
The Remote Setpoint can be assigned to Loop 1, Loop 2, or both. Remote setpoint limits are the same as setpoint limits.
Hardware Configuration
This optional feature is available only if ordered originally from the factory, Product #545-xxxxxBxx00 or #545-xxxxxExx00). Refer to the order code in Chapter 1.
Before configuring the software, make sure the corresponding jumper is set properly. Refer to Chapter 4 to check or change jumper positions.
Software Configuration
1. Go to the REM. SETPT. menu.
2. Set TYPE V/mA to define the input signal range (e.g. 4-20mA).
3. RSP:LO. RNG. and RSP: HI RNG. define the range of the remote setpoint in engineering units. The correct range will be dependent on the source of the remote setpoint signal.
4. RSP:LOW and RSP:HIGH set limits on the remote setpoint value in engineering units.
5. TRACKING determines whether or not the controller will revert to a local setpoint if the remote setpoint signal is lost. This prevents a process upset due to a sudden change in setpoint.
6. BIAS LOW and BIAS HIGH set limits on an operator entered bias value.
7. RSP FIXED determines the signal to which the controller will revert when a lost RSP is restored (fixed). Options are to stay in local or automatically return to remote setpoint.
8. To bias or ratio the remote setpoint value:
a. Go to the TUNING menu. b. Set RSP BIAS and RSP RATIO values.
88 Chapter 7 545 User's Manual
Basic Operating Procedures
After configuring the hardware and software, select the remote input by:
pressing the SET PT key until RSP shows in the display
using a digital input
J. MULTIPLE SETPOINTS
The 545 can store up to eight local setpoints and use a remote setpoint. One application of this feature is configuring the controller to restrict operators to discrete setpoint choices. The 545 can also store multiple sets of PID parameters (see next section).
Software Configuration
1. Go to the SPECIAL menu.
2. Set NO. OF SP to the number of local setpoints desired.
3. Use the SET PT key to scroll to each local setpoint and set it to the desired value with the or ▼ keys.
4. To link the PID sets to the corresponding local setpoint: Go to the TUNING menu.
Set NO. OF PID to SP NUMBER. For details on multiple sets of PID, refer to the next section in this chapter.
Basic Operating Procedures
To select a set point, toggle the SET PT key to scroll through the setpoints. The displayed setpoint becomes active after two second of key inactivity.
The digital inputs can also be used to select the active setpoints. A single digital input may be used for selecting the seconds setpoint, SP2. A set of two digital inputs per loop may be used, to select up to 4 setpoints per loop (see the section in this Chapter in Digital Inputs).
The SET PT key is lit when a setpoint other than the primary local setpoint is active.
K. MULTIPLE SETS OF PID VALUES
The 545 has the ability to store up to eight sets of PID values. This can be a valuable feature for operating the controller under conditions which require different tuning parameters for optimal control. There are various methods of selecting which set should be active. These methods are explained in this section.
Applications
Software Configuration
1. Go to the TUNING menu.
2. NO.OF PID is the desired number of PID sets to be stored. SP NUMBER automatically sets this value equal to the number of stored local setpoints (each PID set will be active when its respective local setpoint is active).
3. PID TRIP determines which variable selects the various PID sets: process variable, setpoint or deviation from setpoint.
4. TRIP:X defines the point (in the PV range) at which that set of PID values become active.
Basic Operating Procedures
A PID set can be selected in one of four ways.
• For NO. OF PID = SP NUMBER, the active set of PID values is the same as the active setpoint. For example, if SP3 is active, then PID set #3 will be active.
• When using PID trip values, a PID set becomes active when the variable exceeds its trip point.
For example, if PID TRIP = SETPOINT, and TRIP:2 = 500, the second set of PID values becomes active when the setpoint exceeds 500, and remains active until the setpoint drops below 500 or exceeds the next highest trip point. The PID set with the lowest trip point is also active when the trip variable is less than the trip value. (The user can set the lowest trip point = the low end of the process variable range, but this is not required.)
• A digital input can be set to trip to the second set of PID upon closure, which overrides a selection based on trip points.
Using with Adaptive and Pretune
The 545 can be programmed to automatically set the PID values using the Pretune and Adaptive Tuning functions. For both functions, the tuned set of PID is that which is active upon initiation of the tuning function.
The controller cannot trip to other PID sets (based on trip point or the digital input
545 User's Manual Chapter 7 89
Applications
contact) until Adaptive Tuning is disabled. However, if the PID set is tied to the corresponding local setpoint, the active PID set values will change with the local setpoint.
Each PID set has 5 parameters that control its function—proportional band, reset, rate, manual reset (or loadline), and trip point. For each set (2 thru 8), these values have to be manually set.
1. Press MENU to access the TUNING menu.
2. Set values for parameters 1 thru 20 (these include the first PID set)
3. Press MENU to access these parameters for each additional PID set (2 through 8): PROP. BND, RESET, RATE, MAN. RST. and TRIP.
L. POWERBACK
POWERBACK is Moore Industries’ proprietary algorithm which, when invoked by the user, reduces or eliminates setpoint overshoot at power up or after setpoint changes. Powerback monitors the process variable to make predictive adjustments to control parameters, which in turn helps to eliminate overshoot of the Setpoint.
Software Configuration
1. Go to the TUNING menu.
2. Set POWR.BACK parameter to ENABLED.
3. Go to the SELF TUNE menu.
4. The DEAD TIME is the time between initiation of an input change and the start of an observable response in the process variable. Pretune will automatically calculate a value for this parameter. However, if Pretune is not run, or results are poor, value choices are:
R 10 to 3200 seconds D 7200 seconds
M. SELF TUNE—POWERTUNE
The Self Tune function of the 545 consists of two distinct components, Pretune and Adaptive Tune. These components may be used independently or in conjunction with one another. For best results, we recommend using them together.

Pretune
This algorithm has three versions. Choose the type that most closely matches the process to optimize the calculation of the PID parameters. The three Pretune types are:
• TYPE 1 Normally used for slow thermal processes
• TYPE 2 Normally used for fast fluid or pressure processes
• TYPE 3 Normally used for level control applications
Pretune is an on-demand function. Upon initiation, there is a five second period during which the controller monitors the activity of the process variable. Then the control output is manipulated and the response of the process variable is monitored. From this information, the initial Proportional Band, Reset and Rate (P, I and D values) and Dead Time are cal culated. When using TYPE 2 or TYPE 3 Pretune, the Noise Band (NOISE BND.) and Response Time (RESP. TIME) and DEAD TIME will also be calculated.
90 Chapter 7 545 User's Manual
In order to run this algorithm, the process must fulfill these requirements:
• The process must be stable with the output in the manual mode;
• For tuning a non-integrating process, the process must be able to reach a stabilization point after a manual step change; and
• The process should not be subject to load changes while Pretune operates.
If these conditions are not fulfilled, set the Adaptive Tune to run by itself.
Applications
Adaptive Tune
Adaptive Tune continuously monitors the process and natural disturbances and makes adjustments in the tuning parameters to compensate for these changes. In order to make accurate calculations, Adaptive Tune needs noise band and response time values. Pretune TYPE 2 and TYPE 3 automatically calculate these values. These values may also be entered or changed manually in the SELF TUNE menu. For Pretune TYPE 1, Noise Band, Response Time and Dead Time parameters must be entered manually.
Figure 7.12 illustrates the relationship between Pretune and Adaptive Tune
Software Configurations
Pretune by Itself
1. Go to the SELF TUNE menu (press MENU+FAST)
2. Set the TYPE parameter to PRETUNE.
3. Set the PRETUNE type to the one that best matches the process (see above section).
4. The next parameter, TUNE PT., appears only for TYPE 1 pretune. This parameter sets the PV point at which the output will switch off. In thermal processes, this will help prevent overshoot. The default is AUTOMATIC.
5. Set the value for OUT STEP. This parameter defines the size of bump to be used. The resulting disturbance must change the process variable by an amount that significantly exceeds the peak-to-peak process noise, but does not travel beyond the “normal” process variable range.
6. The next two parameters, LOW LIMIT and HI LIMIT, set the process variable boundaries. If these boundaries are exceeded during the Pretune, the pretune cycle will abort and return to manual control at the output level prior to the initiation of pretune.
7. The next parameter, TIMEOUT, defines the maximum time in minutes within which pretune must complete its calculations before it is aborted.
The first time a pretune is performed, set TIMEOUT to its maximum value. Make note of the length of the pretune cycle. Then, adjust TIMEOUT to a value about twice the pretune time.
The purpose of this parameter is to prevent a Pretune cycle from continuing for an excessive period of time if a problem develops. The value has no impact on the PID values being calculated.
8. Next is MODE. This defines what mode the controller will enter when pretune is completed. Select MANUAL if there will be a need to review PID parameters before attempting to control with them; the default is AUTOMATIC.
9. If POWERBACK algorithm is being utilized, set a value for DEAD TIME.
10.Place the controller under manual control.
CAUTION! Disable Adaptive Tuning before
altering process conditions (e.g., for shutdown, tank draining, etc.). Otherwise, the 545 will attempt to adapt the Tuning parameters to the temporary process conditions.
Adaptive Tune can be disabled via digital input (if applicable—see Digital Inputs in this chapter), or via menus:
1. Go to the TUNING menu.
2. Go to parameter ADAPTIVE. Change the value to DISABLED.
