1.1.3 CONTROL
Instruments can be programmed for On-Off, Time Proportioning, Current Proportioning, or Position Proportioning control implementations. Selectable direct or reverse control action is also provided. Proportional control implementations are provided with fully programmable PID parameters.
Automatic to Manual switching is easily accomplished via the Standby mode . Switching is bumpless, and while in manual, manipulation of proportional outputs is possible.
Other standard control features include control output limits, setpoint limits, anti-reset windup control, and a unique Automatic Transfer function, which, if configured, allows manual control of the process until setpoint is reached, at which time the unit will automatically transfer from manual to automatic control.
Remote Run-Hold capability can be provided via the Auxiliary Input.
1.1.4 PROGRAMMABLE SETPOINT PROFILES
Up to eight profiles can be programmed on any of these Profile Controllers. Each of the eight profiles can contain up to six segments. Each segment contains a ramp and a soak operation. Profiles can be programmed to run continuously or any number of times up to
9999. A combination of profiles may be combined for back to back execution. This has the affect of acting as a single profile of more than six segments.
Assured Soak is provided with the use of two programmable parameters that will activate an Auto/Hold feature. This feature will place a running profile in the Hold condition and prohibit a Soak operation from starting or completing if an acceptable process value is not reached and then maintained.
Event outputs may also be provided. Up to three events may be assigned and can be turned on or off at the beginning of each ramp and soak.
1.1.5 ALARMS
Alarm settings are fully programmable. Alarm type may be set as Process direct or reverse (High or Low), Deviation direct or reverse (above or below setpoint), or Deviation Band type (closed or open within band).
Alarm outputs can be provided by assigning any specified relays (SPST or SSR driver) to the respective alarm.
1.1.6 DIGITAL COMMUNICATIONS
The instrument can be provided with an RS-422/485 communications port which allows bi-directional multidrop communications with a supervisory computer.
Installation and Wiring 2.1
Read these instructions carefully before proceeding with installation and operation. Electrical code requirements and safety standards should be observed. Installation should be performed by qualified personnel.
CAUTION: The Instrument AC power input is specified in the model number and on the wiring label for either 115VAC or 230VAC. Verfiy the AC power input required by the instrument prior to proceeding with installation.
Unpacking 2.2
Remove the instrument from the carton and inspect it for any damage due to shipment. If any damage is noticed due to transit, report and file a claim with the carrier. Write the model number and serial number of the instrument on the front cover of this Operation Manual for future reference when corresponding with the factory.
Location 2.3
Locate the instrument away from excessive moisture, oil, dust, and vibration. Do not subject the instrument to operating temperatures outside of 0 to 55˚ C (32° to 131° F).

Mounting 2.4
Figure 2-1 (page 8) shows installation view and physical dimensions for the panel mounted instrument.
The electronics can be removed from the housing for installation, if so desired. To remove, loosen the locking screw centered on the bottom face of the unit. The instrument pulls straight out. When installing, be sure that the verically mounted circuit boards are inserted in the correct grooves in the top and bottom of the housing. Also make sure the screw lock is sufficiently tight. When installing multiple instruments, be sure to reinsert the proper instrument into its correct enclosure by matching the serial number with the number inside the housing. This will insure that the accuracy of the control will be within the published specifications. The ambient compensator on the rear of the enclosure is calibrated to the electronics at the factory.
Cut the panel cutout to the dimensions shown in Figure 2-1 (page 8). Insert the instrument housing into the panel cutout and install the mounting bracket. Place the mounting screws on the back of the housing and tighten until the instrument is rigidly mounted. Do not overtighten.
A surface mounting kit is available - part number 64405801. For installation of the instrument in areas subjected to washdowns, a water tight cover option is available (part # 64417801).

Preparation for Wiring 2.5
2.5.1 WIRING GUIDELINES
Electrical noise is a phenomenon typical of industrial environments. The following are guidelines that must be followed to minimize the effect of noise upon any instrumentation.
2.5.1.1 INSTALLATION CONSIDERATIONS
Listed below are some of the common sources of electrical noise in the industrial environment:
• Ignition Transformers
• Arc Welders
• Mechanical contact relay(s)
• Solenoids Before using any instrument near the devices listed, the instructions below should be
followed:
1. If the instrument is to be mounted in the same panel as any of the listed devices, separate them by the largest distance possible. For maximum electrical noise reduction, the noise generating devices should be mounted in a separate enclosure.
2. If possible, eliminate mechanical contact relay(s) and replace with solid state relays. If a mechanical relay being powered by an instrument output device cannot be replaced, a solid state relay can be used to isolate the instrument.
3. A separate isolation transformer to feed only instrumentation should be considered. The transformer can isolate the instrument from noise found on the AC power input.
4. If the instrument is being installed on existing equipment, the wiring in the area should be checked to insure that good wiring practicies have been followed.
2.5.1.2 AC POWER WIRING
Earth Ground The instrument includes noise suppression components that require an earth ground connec­tion to function. To verify that a good earth ground is being attached, make a resistance check from the instrument chassis to the nearest metal water pipe or proven earth ground. This reading should not exceed 100 ohms.
Neutral (For 115VAC) It is good practice to assure that the AC neutral is at or near ground potential. To verify this, a voltmeter check between neutral and ground should be done. On the AC range, the reading should not be more than 50 millivolts. If it is greater than this amount, the secondary of this AC transformer supplying the instrument should be checked by an electrician. A proper neutral will help ensure maximum performance from the instrument.
PAGE 9
2.5.1.3 WIRE ISOLATION
Four voltage levels of input and output wiring may be used with the unit: * Analog input or output (i.e. thermocouple, RTD, VDC, mVDC or mADC) * SPST Relays * SSR driver outputs * AC power
The only wires that should be run together are those of the same category. If they need to be run parallel with any of the other lines, maintain a minimum 6 inch space between the wires. If wires must cross each other, do so at 90 degrees. This will minimize the contact with each other and reduces "cross talk".
emitted by a wire as current passes through it. This EMF can be picked up by other wires running in the same bundle or conduit.
In applications where a High Voltage Transformer is used, (i.e. ignition systems) the secon­dary of the transformer should be isolated from all other cables.
This instrument has been designed to operate in noisy environments, however, in some cases even with proper wiring it may be necessary to suppress the noise at its source.
2.5.1.4 USE OF SHIELDED CABLE
Shielded cable helps eliminate electrical noise being induced on the wires. All analog signals should be run with shielded cable. Connection lead length should be kept as short as possible, keeping the wires protected by the shielding. The shield should be grounded at one end only. The preferred grounding location is at the sensor, transmitter or transducer.
"Cross talk" is due to the EMF (Electro Magnetic Flux)
PAGE 10
2.5.1.5 NOISE SUPPRESSION AT THE SOURCE
Usually when good wiring practices are followed, no further noise protection is necessary. Sometimes in severe electrical environments, the amount of noise is so great that it has to be suppressed at the source. Many manufacturers of relays, contactors, etc. supply "surge suppressors" which mount on the noise source.
For those devices thta do not have surge suppressors supplied, RC (resistance-capacitance) networks and/or MOV (metal oxide varistors) may be added.
Inductive Coils - MOV's are recommended for transient suppression in inductive coils con­nected in parallel and as close as possible to the coil. See Figure 2-2. Additional protection may be provided by adding an RC network across the MOV.
Contacts - Arcing may occur across contacts when the contact opens and closes. This results in electrical noise as well as damage to the contacts. Connecting a RC network properly sized can eliminate this arc.
For circuits up to 3 amps, a combination of a 47 ohm resistor and 0.1 microfarad capacitor (1000 volts) is recommended. For circuits from 3 to 5 amps, connect 2 of these in parallel. See Figure 2-3.

2.5.2 SENSOR PLACEMENT (Thermocouple or RTD)
If the temperature probe is to be sufnected to corrosive or abrasive conditions, it should be protected by the appropriate thermowell. The probe should be positioned to reflect true process temperature:
In liquid media - the most agitated area.
In air - the best circulated area.
THERMOCOUPLE LEAD RESISTANCE
Thermocouple lead length can affect instrument accuracy since the size (gauge) and the length of the wire affect lead resistance.
To determine the temperature error resulting from the lead length resistance, use the follow­ing equation:
Terr = TLe * L where; TLe = value from appropriate table below
L = length of leadwire in thousands of feet

Example: An MIC is to be located in a control room 660 feet away from the process. Using 16 AWG, type J thermocouple, how much error is induced?
Terr = TLe * L
TLe = 2.47 (°F/1000 ft) from Table 2 Terr = 2.47 (°F/1000 ft) * 660 ft Terr = 1.6 °F
PAGE 12
RTD LEAD RESISTANCE
RTD lead length can affect instrument accuracy, since the size (gauge) and length of the wire affect lead resistance.
To determine the temperature error resulting from the lead length resistance, use the following equation:
Terr = TLe * L where; TLe = value from Table 3 if 3 wire RTD or Table 4 if 2 wire RTD
L = length of lead wire in thousands of feet
TABLE 3 - 3 Wire RTD AWG No. Error °C Error °F
10 +/- 0.04 +/- 0.07 12 +/- 0.07 +/- 0.11 14 +/- 0.10 +/- 0.18 16 +/- 0.16 +/- 0.29 18 +/- 0.26 +/- 0.46 20 +/- 0.41 +/- 0.73 24 +/- 0.65 +/- 1.17
TABLE 4 - 2 Wire RTD AWG No. Error °C Error °F
10 +/- 5.32 +/- 9.31 12 +/- 9.31 +/- 14.6 14 +/- 13.3 +/- 23.9 16 +/- 21.3 +/- 38.6 18 +/- 34.6 +/- 61.2 20 +/- 54.5 +/- 97.1 24 +/- 86.5 +/- 155.6
Example: An application uses 2000 feet of 18 AWG copper lead wire for a 3 wire RTD sensor. What is the worst case error due to this leadwire length?
Terr = TLe * L
TLe = +/- .46 (°F/1000 ft) from Table 3 Terr = +/- .46 (°F/1000 ft) * 2000 ft Terr = +/- 0.92°F
Wiring Connections 2.6
All wiring connections are typically made to the instrument with it installed. Terminal connec­tions should be made via the rear panel with 14 gauge wire maximum (see Figure 2-4).

Configuration 3.1
After completing installation of the unit, the configuration procedures contained within this section must be performed to prepare the instrument for operation on the intended application. The procedures include selecting specific parameters, entering data and possible jumper positioning.
Parameter selections and data entry are made via the front keypad. To ease configuration and operation, user entered data has been divided up into several modes. Each mode contains a different type of data or may be used for specific operating functions. These modes are as follows:

(Continued on next page)
PAGE 22
Associated with each mode is a series of unique displays which are accessed via the front keypad.
Prior to first time operation of the instrument, the configuration procedures for the Program, Profile Entry and Tune modes must be performed as applicable. The Control, Off, Standby, Profile Continue and Profile execution (P1 thru P8) modes are discussed in Section
4.1 (page 38) of this manual. Calibration and Test modes are not used as part of instrument configuration or operation.
These are used for service and maintenance functions and are discussed in Section 5.2 (page 47) of this manual.
Shipped Configuration/ Jumper Positioning 3.2
All configuration parameters in each mode are set to default values. These defaults are shown in tabular form under the description for each mode. Instrument AC power input is as specified in the instrument model number and as shown on the instrument ratings label.
3.2.1 JUMPER POSITIONING
Jumpers are used in all instruments to provide a security lockout feature and to condition the process input . All jumpers are typically of the three pin type and have two functions. All jumpers are either located on the Options Board or the Processor Board. Board layouts and jumper locations are shown in Appendix A-2 and A-3 (pages 64 and 65 or 66).
Check the actual jumper position in the instrument to be configured and verify the proper position for the intended application. If the current position is not correct, make changes.
Start up Procedures 3.3
Step by step procedures are provided in Tables 3-1 thru 3-4 . These tables provide the display sequence, parameter adjustment and factory setting for each step.
The instrument is provided with a "time out" feature. If the instrument is in any mode and no keypad activity takes place for 30 seconds, the instrument will "time out" and exit the mode automatically. The instrument will display the code for the respective mode. If a mode code is displayed for 5 seconds with no activity it will then "time out" and proceed to either the Control or Off mode, depending upon which operational state the instrument was in last.
3.3.1 POWER UP PROCEDURE
A. Verify that all electrical connections have been properly made before applying power to the instrument.
If the instrument is being configured for the first time, it may be desirable to disconnect the controller output connections as the instrument may go into the Control mode automatically following the power up sequence. Upon verification, power may be applied.
B. Upon power up, "6XXX" will be displayed (X representing digits), then "XXX-", identifying the seven digit model number as defined in the order matrix. Next, the software revision level will be displayed in the format "rX.XX". Then "tSt1", "tSt2", and "tSt3" will be displayed while Test 1 thru 3 are executed automatically. Upon successful completion of these tests, "Ctrl" (for the Control mode) or "oFF" (for the Off mode) will be displayed for about three seconds. During this time the operator may select another mode prior to the instrument automatically going into the Control mode.
C. If any error messages are displayed, refer to Section 5.4, page 56 for a definition of these error messages and the required action.
D. If the instrument has been configured or operated previously, the mode that the instrument will go into upon power up, depends on what mode the instrument was in on power-down and how it has been programmed.
Front Panel Operation 3.4
3.4.1 DIGITAL DISPLAY AND STATUS LED's
The digital display provided has 4 digits and a decimal point. Each digit has seven segments and is capable of producing numeric characters from 0-9 and certain alpha characters. The digital display is used to provide indication of process variable as well as displaying codes used for configuration and operation of the instrument. The display includes the following Status Indicator LED's:

Operation 4.1
4.1.1 OFF MODE
In the Off Mode, the instrument control, process retransmission signal(s) and alarm function(s) are turned off. The Off mode can be entered by pressing and releasing the SCROLL key until the display reads oFF, then pressing the DOWN key. The display will read oFF and then the current process variable at two second intervals. This sequence will repeat to indicate that the instrument is in the Off mode.
4.1.2 CONTROL MODE
In the Control mode, the instrument control function(s) and alarm(s) are actively responding to the process variable as selected in the Program and Tune modes. The control mode allows setpoint changes from local setpoint (standard) adjustment by an operator at the front keypad. Other operations in the Control mode include a lamp test and proportional output % display.
4.1.2.1 DIRECT/REVERSE OPERATION OF OUTPUTS
Direct operation is typically used with cooling applications. On-Off direct output(s) will turn on when the process variable exceeds setpoint. Proportional direct output(s) will increase the precentage of output as the process value increases within the proportional band.
Reverse operation is typically used with heating applications. On-Off reverse output(s) will turn off when the process variable exceeds setpoint. Proportional reverse output(s) will decrease the percentage of output as the process value increases within the proportional band.
4.1.2.2 LOCAL SETPOINT OPERATION
The instrument must be in the Control mode to allow the setpoint value to be adjusted. In the Control mode, to view the setpoint, press and release the UP or DOWN key. The green LED under the SP label will light to indicate that the displayed value is the setpoint. To change the setpoint value, press and hold the appropriate key. Press and hold the UP key to increase the setpoint or press and hold the DOWN key to decrease the setpoint. The setpoint will change slowly at first then faster as the key is held pressed. If the setpoint will not increase, check the Program mode (page 25) to see that you are not trying to increase the setpoint above the setpoint limit SPL. Check that the Setpoint Change mode is on in the Enable mode.
4.1.2.3 PROFILE OPERATION
To start a profile, press and release the SCROLL key to sequence the display to the profile number display code P1, P2, etc. With the desired profile number displayed, press either the DOWN or the RUN/HOLD to start the profile. run will be displayed for about 2 seconds to indicated that the profile is starting. The status lamps will indicate which segment is active and if the profile is in the ramp or soak portion of the segment.
To stop a profile that is running, press the RUN/HOLD key. The display will show hold for about 2 seconds, then the process value for about 2 seconds and then continue to display this sequence. The profile timer will stop but the control, alarm, and event outputs will remain active. The profile can be restarted by pressing the RUN/HOLD key. To exit the profile, go to hold and then press and release the SCROLL key until the display shows oFF or CtrL, then press the DOWN key. Pressing the DOWN key with oFF displayed will cause the control, alarm, and events to be turned off. (Pressing the DOWN key with CtrL displayed will leave the events as they were, and the control and alarm outputs will remain active). The setpoint will be the last setpoint seen in the profile.
While a profile is running, it is possible to display additional profile status information. To activate the Profile Execution Status Display sequence, hold the DOWN key and press the SCROLL key. This will cause the display to sequence through the following series of display codes and values:
Display Code Description Value
Pn Profile Number Actual Profile Number tr Time remaining in current Ramp or Soak Actual time remaining value
(in whatever units were config ured in the program mode for
Ptb) E1, E2, E3 Event 1-3 status (if applicable) on or oFF SP Current Setpoint Actual Setpoint Value ProC Current Process Value Actual Process Value PLCt Profile Loop Count remaining Profile Loop count Value
Each code or value will only be displayed if they are appropriate. Each code or value will be displayed for one second. This sequence will continue until any key is depressed.
To start a profile running at some point within the profile other than start can be accomplished by using the Profile Continue mode.

4.1.2.4 ON-OFF CONTROL
On-Off control can only be implemented on controllers provided with SPST relay or SSR driver output(s). On-Off operation can be assigned to either or both output 1 and 2. The On-Off control can be selected as direct or reverse acting. Direct action is typically used in cooling applications. The output device will turn on when the process value is greater than the setpoint. Reverse action is typically a heating application. The output device will turn on if the process value is below the setpoint. A hysteresis adjustment is provided for On-Off outputs. This adjustment is in terms of degrees/engineering units and defines the width of the hysteresis bandwidth about the setpoint. This parameter may also be referred to as a dead band. Relay chatter can be eliminated by proper adjustment of this parameter. When operating in On-Off control, the control algorithm will turn the output on or off depending upon the setpoint, the relative position of the process value, and the hysteresis adjustment. The respective OUT1 or OUT2 indicator will illuminate to indicate that the output device is on. The hysteresis will also affect the operation of the alarm output if used.
PAGE 41
4.1.2.5 TIME PROPORTIONING CONTROL
Time Proportioning Control can be implemented on controllers provided with SPST relay or SSR driver output(s). Time proportioning can be programmed for output 1 and/or 2. Time Proportioning control is accomplished by cycling the output on and off when the process value is within the proportional bandwidth selected at a prescribed time period. The time period is selected in the Tune mode by adjusting Ct1 and/or Ct2. The on time is a percent­age of the Cycle Time.
Example: Calculated output % = 40%; Cycle Time adjustment = 20 seconds
Output on time = .4 x 20 = 8 seconds Output off time = .6 x 20 = 12 seconds
4.1.2.6 CURRENT PROPORTIONING CONTROL
Current Proportioning control provides a proportional current output in response to process value and setpoint. The current output can be selected for direct or reverse operation. Direct current output control is typically used for cooling applications. The current output will increase as the process value increases within the proportional bandwidth selected. The reverse current output control is typically used in heating applications. The current output will decrease as the process value increases within the proportional bandwidth selected.
The instrument can be programmed to provide 0 to 20mADC or 4 to 20mADC (if EO option is present) current output(s). The output selected is dependent upon the final control element being used in the process. The output 1 and/or output 2 LED will be lighted whenever the Current Proportional outputs are selected.
PAGE 42

4.1.2.7 POSITION PROPORTIONING CONTROL
Position Proportioning control can be implemented on those controllers provided with two SPST relay outputs or two SSR Driver outputs and Slidewire Feedback option.
Positioning proportioning control permits the use of PID control where the final control element is a modulating device such as a motorized valve. In this form, each of the two required relays or SSR Drivers will be used to control the valve. One output is used to open the valve, the other is used to close the valve. The slidewire feedback is used to provide a signal relative to the valve armature position to the instrument.
As with the other proportioning control forms, the process input, tuning parameters and the setpoint are used by the control algorithm to calculate the output % requried to correct for the deviation between setpoint and process.
With Position Proportioning control, it may be necessary to adjust the Sensitivity (SEnS) Tune mode parameter to reduce or eliminate oscillations of the motor around setpoint. If oscillation occurs, increase the SEnS value until the motor stops oscillating. If the differential between the Open and Closed rotation is too large, then decrease the SEnS value. Also, for proper Position Proportioning operation, it is necessary to specify the actuation time of the valve or damper from full open to full closed. If the motor has a stroke duration of 60 seconds, change the value in the Cycle Time parameter Ct1 to 60. This ensures that the controller will move the motor for the proper amount of time when making adjustments.
4.1.2.8 DUAL OUTPUT CONTROL
Dual output control can be performed when two outputs are specified. The outputs may be programmed for On-Off, Time Proportioning, or Current Proportioning, as applicable.
The output action is dependent upon the setpoint, the process value, and Tune mode parameters. If two proporitonal outputs are selected, both output proportional bands will be biased so that 0% of output is seen when the process value equals setpoint. The output(s) can be biased by the use of the Tune mode parameters FOP and SPrd as shown in Figure 4-1 (below).
The first output is programmed as a proportional reverse output and the second as a propor­tional direct output. (See Glossary, page 67, for definitions of these terms). Dual proportion­ing outputs are provided with separate proportional bands and cycle time adjustments for each output.

4.1.2.9 PROPORTIONAL OUTPUT PERCENTAGE DISPLAY
While in the Control mode, press and hold the UP key and then press the SCROLL key to cause the display to sequence through a series of display codes and values:
Po1 Percent Output 1 (if applicable) Output 1% value Po2 Percent Output 2 (if applicable) Output 2% value Proc Process Value Actual Process Value
Each code and output value will be displayed only if the corresponding proportional output is present. Each code or value will be displayed for 1 second. This sequence of displays will continue until the SCROLL key is pressed, which will then return the display to the normal mode.
4.1.3 MANUAL MODE FOR PROPORTIONAL OUTPUTS
Manual adjustments of the proportional output(s) can be used to test the operation of the output(s), while tuning to establish basic process control, or to provide control of the proportional output(s) during the occurance of certain error conditions.
Note: The proportional output(s) do not change automatically in response to changes in the process while in the Manual mode. Be sure to pay close attention to the process to avoid damage.
To enter the Manual mode, press and release the SCROLL key until you see Stby. Then press the DOWN key . The Manual mode status LED will light to indicate that the Manual mode is in use. Shifting from the Control to the Manual mode is bumpless. The proportional output(s) will stay at the last value(s) calculated by the control algorithm. Po1 will appear on the display if output 1 is a proportional output or Po2 if output 1 is not a proportional control. If no keys are pressed, the display will sequence through the following displays:
PAGE 43
Po1 if output 1 is 3, 4, 5, 6, 7 then the output 1 percentage of output value Po2 if output 2 is 3, 4, 5, 6 then the output 2 percentage of output value. Proc will be displayed, then the current process value.
In order to vary a proportional output percentage value, press and release the SCROLL key until the display code for the output is displayed Po1 or Po2. Press and release the SCROLL key again to see the percentage of output value. Press the UP key to increase the output percentage value. Press the DOWN key to decrease the output percentage value.
To return to the Control mode of operation from the Manual mode, press the SCROLL key until you see Po1 or Po2 then press the UP key. The display will change to Stby. Press the SCROLL key until you see the mode you wish to enter, then press the DOWN key. If the Automatic Transfer feature is selected in the Program mode, the instrument will switch from Manual mode to the Control mode when process value reaches the setpoint value.
4.1.4 PROCESS RE-TRANSMISSION OUTPUT - EO OPTION ONLY
If the instrument is provided with a current output not used for process control, this output may be assigned to provide a linear re-transmission of the process value. This output can be used to provide a process signal to remotely installed recorders, panel meters, or dataloggers. The process output is scaled for the application by using the Program mode parameters process/setpoint value upper Pou and process/setpoint value lower PoL. The current output resolution is @ 200 steps, so for the best re-transmission accuracy, the span between Pou and PoL should be as small as possible. If a current output is used for re-transmisssion, the corresponding control output, out1 or out2, cannot be assigned to it.
Upon an error condition, Process Value output will be set to 0 percent if the 1st output control is direct acting. If the control action is reverse acting, the Process Value output will be set to 100 percent.
PAGE 44
4.1.5 SETPOINT RE-TRANSMISSION OUTPUT - EO OPTION ONLY
If the instrument is provided with a current output not used for process control, this output may be assigned to provide a linear re-transmission of the setpoint value. The setpoint output is scaled for the application by using the Program mode parameters process/setpoint output value upper Pou and process/setpoint output value lower PoL. The current output resolution is @ 200 steps, so for the best re-transmission accuracy, the span between Pou and PoL should be as small as possible. If a current output is used for re-transmission, the corresponding control output, out1 or out2, cannot be assigned to it.
Alarm Operation 4.2
The type of alarm is selected in the Program mode as follows:
1. Process Alarm Direct - the alarm will be on if the process value is greater than the process value selected.
2. Process Alarm Reverse - the alarm will be on if the process value is less then the process value selected.
3. Deviation Alarm Direct - the alarm will be on if the process value is greater than the setpoint plus the deviation value selected.
4. Devation Alarm Reverse - the alarm will be on if the process value is less than the setpoint plus the devation value selected.
5. Deviation Band Alarm Open Within - the alarm will be on if the process value is greater than one half the deviation band alarm values selected above or below the setpoint.
6. Deviation Band Alarm Closed Within - the alarm will be on if the process value is less than one half the deviation band value selected above or below the setpoint.
The alarm will be active while the instrument is in the Control mode or while the profile is running. Relay and solid state relay drivers can be assigned to provide output capability to the alarm function.
The alarm value (Process, deviation or bandwidth) is selected in the Tune mode. Alarm output chatter can be reduced by using the hysteresis parameter in the Program mode
to create a deadband around the alarm point.
Tune Mode Operation 4.3
Proportional output control may require the adjustment (tuning) of the PID and other related parameters. This provides a means for the instrument's control algorithm to be adjusted to meet specific application requirements.
4.3.1 SYSTEMATIC TUNING METHOD
1. Changes in tuning parameters should be made one at a time.
2. After making any changes in tuning parameters, a disturbance should be introduced into the process so that the process reaction may be observed. This process reaction, or recovery, will tell whether the tuning parameters provide the desired control. It is usually easiest to make a step change in setpoint to introduce this disturbance.
3. The change in setpoint, or disturbance, referenced above should be large enough to cause an observable deviation of process from setpoint. However, this change should not be so large that it will cause the controller output to proceed to either extreme limit.
4. Controller tuning for optimal control is not hard and fast, BE PATIENT. The process will take a certain amount of time to react to the setpoint changes during tuning. The amount of time depends upon the specific process, however, a period of 8 to 12 minutes should be allowed between changes. The important point to remember is to allow the process to react completely, do not rush through tuning of the controller. If the complete process reaction is not observed, optimum control may never be achieved.
5. Time Proportioning control output(s) require(s) the cycle time to be adjusted for the application. Short cycle times typically result in the most accurate process control, but will cause the quickest wear out of any mechanical components.
6. Leave all other tuning parameters (except for the alarm settings, if used) at the factory default settings. Obtain the best possible process reaction by adjusting the Proportional Bandwidth parameter. The setting that achieves the best response for the process should be left in the controller programming, and should be noted on the Software Reference Sheet in Appendix E (page 75).
7. If there are to be no setpoint or load changes in the process, the Proportional Band adjustment may be all that is necessary for proper control. If an offset still exists (the process does not settle out at setpoint with the best possible proportional band adjustment) Manual Reset may be added to eliminate this offset.
PAGE 45
8. Auto Reset may be added to eliminate offsets and improve response to setpoint and load changes. Increase Auto Reset from 0 in 0.2 increments. Start with a small amount. Increase this increment if there is no apparent reaction. Remember to allow the process 8 to 12 minutes to react.
9. If necessary, Rate may be added. Rate is a dynamic tuning parameter. Rate may be required to compensate for process lags or to help inhibit reset windup when a large amount of Auto Reset (4 or 5 repeats per minute) is being used.
10. Controller tuning is not hard and fast. It may be necessary to adjust the tuning parameters over a period of time to obtain optimal control of the process.
4.3.2 ZIEGLER NICHOLS TUNING METHOD
This procedure has been determined empirically to yield 1/4 ampitude decay tuning parame­ters that are determined by watching the system in a sustained oscillation (curve C, page 46) the ultimate proportional band and ultimate time period) and then using these values from this sustained oscillation to calculate ideal parameters.
Determining Ultimate Proportional Band and Ultimate Time Period
1. Set Manual Reset rSet to 0.0, set ArSt to 0.0 and set rAtE to 0.0
2. Enter the Control mode of operation, observe the process reaction.
3. Set the Proportional Band (PB) at 100 and upset the process and observe the response. One easy method for imposing the upset is to move the setpoint for a few seconds and then return it to its original value.
(Continued on next page)
PAGE 46
4. Achieve a response curve similiar to the sustained oscillation (curve C), this is the Ultimate Proportional Band (UPB) and Ultimate Time Period (UTP).
a) If the response curve from step 3 does not damp out, as in Curve A from the drawing, the PB is too low. The PB should be increased and step 3 repeated.
b) If the response in step 3 damps out, the PB is too high. The PB should be decreased and step 3 repeated.
These values obtained for Ultimate Proportional Band (UPB) and Ultimate Time Period (UTP) are used to calculate ideal P, PI, PD, PID tuning parameters using the following Ziegler­Nichols equations:
Proportional only control (P) -
P(Pb) = 2 x UPB (degrees or units)
Proportional plus automatic reset (PI) -
P (Pb) = 2.2 x UPB (degrees or units) I (ArSt) = 1.2 / UTP (repeats per minute)
Proportional plus derivative (or rate) (PD) -
P (Pb) = 1.7 x UPB (degrees or units) D (rAtE) = UTP / 8 (minutes)
Proportional plus automatic reset plus derivative (PID)
P (Pb) = 1.7 x UPB (degrees or units) I (ArSt) = 2 / UTP (repeats per minute) D (rAtE) = UTP / 8 (minutes)
If an overdamped response is desired, multiply the proportional band by two.

voltage and millivolt inputs.
CAL 3 Cold Junction Compensation calibration used to correct for component
variation in CJC circuit.
CAL 4 Cold Junction utility. The temperature of the cold junction is displayed. No
adjustment is made with this procedure.
CAL 5 RTD input calibration used to correct for component differences in the RTD
input circuit. CAL 6 CJC turn on/off. CAL 7 Factory Use Only. CAL 8 Re-initialization of all profile information
5.2.1 CAL 1 PARAMETER INITIALIZATION
This procedure is performed to erase the information that was entered in the Program and Tune modes. All parameters will be reset to default values. Prior to beginning this procedure record the Program and Tune mode parameters so that they can be re-entered. No special test equipment is required.
With CAL 1 displayed, depress and hold the DOWN key, then press the SCROLL key. The display will momentarily go blank. Release the keys. CAL 1 will reappear on the display. This calibration can be done again or another may be selected.
5.2.2 CAL 2 MAIN CALIBRATION
This procedure determines and saves calibration values which correct for component variations relating to the input measuring function of the instrument. This is the only calibration required for the volt and millivolt inputs. Additional calibration procedures are required for thermocouple and RTD inputs.
A 50.00 ± .01 mVDC source is required for calibrating. In addition, make sure that JU1 on the Processor board is in the "non volt" position. See Appendix A-2 (page 64).
Make sure all input wiring is disconnected. Short the input terminals 1 and 3 or apply
0.00 ± mV to the input. With CAL2 displayed, press and hold the DOWN key, then press the SCROLL key. Release both keys and the instrument will display hLd1. Depress the DOWN key; dELy will appear for up to ten seconds, then SCAn will appear for up to ten seconds. If the calibration reference number which appears is not between -50 and +50, proceed per note below. Otherwise, connect a 50.00 ± .01 mV source to the input terminals. Press the DOWN key and dELy will be displayed for ten seconds and the SCAn for ten seconds. Then CAL2 will reappear. If there is a problem, the appropriate error code will be displayed. Restore JU1 to the position necessary for the input type.
NOTE: If the calibration reference number falls outside the -50 to +50 range, depress the SCROLL key and CAL2 will be displayed. Depress the DOWN key and perform the calibration once more. Repeat the calibration until the number falls within the toler­ance limits. If the calibration number remains outside these limits, check the connec­tions to the test equipment and try the calibration again. If the number still does not aproach the tolerance limits contact an Applications Service Engineer at the factory or a local representative.
Error Recover - see 5.4 (page 56) for details. However, be sure that the millivolt source is securely connected, functioning properly and the polarity is correct. Press the DOWN key to bring the instrument back to dELy and try the calibration again. The calibration can be exited at anytime. hLd1 or the reference number is displayed by pressing the SCROLL key.
CAL 2 QUICK CALIBRATION
This routine will allow the operator to execute a rough calibration on their unit via the keypad with no other equipment or disturbance to established wiring. It is intended to provide a partial recovery from a calibration corruption where the necessary equipment indicated in Cal 2-5 may not be available. It should be noted that this is not intended as a substitution to the main calibration procedure described earlier and may considerably deter from the accuracy of the instrument.
With CAL2 displayed, press and hold the DOWN ARROW key, then press the SCROLL key. Release both keys and the instrumet will display hLd1. Press and hold the UP ARROW key, then press the SCROLL key. The display will momentarily blank and then CAL1 will be displayed. Release both keys and depress the UP ARROW key. CAL will be displayed.
PAGE 49
5.2.3 CAL 3 COLD JUNCTION COMPENSATION
This procedure determines and saves calibration values which correct for component vari­ations relating to the cold junction compensation. This calibration must be preceded by CAL2 the main calibration, to properly calibrate the instrument. These two calibrations are all that is needed for proper operation with thermocouple inputs.
Test equipment: : one type J thermocouple and one mercury thermometer, accurate to ± .25 degrees C or equivalent are required.
Make sure all input wiring is disconnected and connect the J thermocouple to the input. Place the thermometer next to the thermocouple and allow the controller to warm up for 30 minutes, before proceeding with the calibration.
With CAL3 displayed, press and hold the DOWN key, then press the SCROLL key and the unit will display hoLd. Release both keys. Press the DOWN key and dELy will be displayed for ten seconds, then SCAn for ten seconds. If SCAn remains in the display for much longer than ten seconds, refer to the the note below. The instrument will compute and display the cold junction temperature to the nearest tenth of a degree C. Compare reading with ther­mometer and use the UP and DOWN keys to correct the reading, if necessary. To end procedure, press the SCROLL key and CAL3 will be displayed again.
NOTE: If the instrument continues to display in SCAn, proceed as follows. With SCAn displayed, press the SCROLL key. The instrument will display hoLd. Press the UP key . The instrument will begin the calibration procedure with a default value and proceed to dELy. Complete calibration as described above.
Error recovery - see section 5.4 (page 56) for details on specific errors. The calibration can be exited at any time. hoLd is displayed by pressing the SCROLL key.

5.2.5 CAL5 RTD INPUT
This procedure determines and saves calibration values relating to RTD inputs. This calibration must be preceded by CAL2 to properly calibrate the instrument. A decade resistance substitution box with .01% resolution or equivalent is required.
Processor board jumper JU1 is in the non-volt position (Appendix A-2, page 64) and that the Option board jumpers JU2 and JU3 are in the proper positions (Appendix A-3, page 65).
With CAL5 displayed, press and hold the DOWN key and then press the SCROLL key. The display will now be hLd1 to indicate that the instrument is set to calibrate the RTD input. Connect the decade box at 100 ohm setting across the input terminals 1 and 3 and a jumper wire from terminal 1 to 5. Press the DOWN key and dELy will be displayed for 10 seconds, then SCAn for ten seconds. When hLd2 is displayed, change the decade box setting to 277 ohms to the input terminals (do not disturb the wiring) and press the DOWN key. The display will change to dELy for 10 seconds, followed by SCAn for ten more seconds. CAL5 will be displayed after the calibration is completed.
Make sure that the
Error recovery: See section 5.4 (page 56) for details on specific errors.
The calibration can be exited when the instrument displays hLd1 or hLd2 by pressing the SCROLL key.
5.2.6 CAL6 COLD JUNCTION COMPENSATION
This routine provides selection of operating modes for the cold junction compensation used for thermocouple inputs.
With CAL6 displayed, press and hold the DOWN key, then press the SCROLL key. The instrument will display C6 and the number of the mode in effect. Press the UP or DOWN key to change the mode selection, indicated by the number to the right of the C6. Pressing the SCROLL key will exit the calibration with the last number displayed in effect.
The selected mode will remain in effect if power is interrupted. To return the instrument to normal operation, CAL6 must be exited, with mode zero selected, or CAL1 must be executed to initalize all parameters.
Mode 0: Normal operating mode. Mode 1: Cold Junction Compensation temperature will be internally fixed at 0 degrees C by
the software to facilitate linearization testing when using an uncompensated millivolt source to simulate thermocouple millivolt input signal.
Note: If the Process Value exceeds 999.9, the leftmost digit will be the letter o with a bar over it. The other digits will be valid.
5.2.7 CAL8 PROFILE REINTIALIZATION
This procedure is used to erase all profiles that have been entered in the instrument. Be sure to record any profile information on the Profile Recording Sheets (Appendix F, pages 78 and
79) so that they can be re-entered. With CAL8 displayed, press and hold the DOWN key, then press the SCROLL key. The
display will blank momentarily and then CAL8 will be displayed.

With tSt6 displayed, press and hold the DOWN key, then press the SCROLL key. oFF will be displayed. For SPST Relay outputs, connect the meter across the relay output in the ohm scale. The meter should read continuity with the relay on and infinity when the relay is off. For SSR Driver outputs, connect the meter across the output in the Volt DC scale. The meter should read 5 VDC when the SSR driver is on and 0 VDC when the driver is off. Press and release the DOWN key to advance through the following sequence:
Display Relay On rLYA A Only rLYb B Only rLYC C Only oFF None
To exit, press the SCROLL key and tSt6 will be displayed. The existence of Relay and Solid State Relay Driver output(s) is dependent upon the hardware configuration.
5.3.7 TEST 7 CURRENT 1 OUTPUT TEST
This test allows the operator to verify that the current output(s) are functioning properly or will allow the selection of an output value for testing of associated equipment. A milliamp meter is required for testing.
With tSt7 displayed, press and hold the DOWN key, then press the SCROLL key. The display will indicate 4 milliamps. Use the UP and/or DOWN key to increase or decrease the current output in 1 mADC steps from 4 to 20mADC. The current output reading should be ± 0.5 mADC at any output value. To exit the test, press the SCROLL key and tSt7 will be displayed. The existence of mADC current output is dependent upon the hardware configuration. See Appendix A-3 (page 65 or 66) to make sure hardware is present.
5.3.8 TEST 8 CURRENT OUTPUT 2 TEST
This test is the same as Test 7 except that it is for Output 2.
5.3.9 TEST 9 AUXILIARY INPUT TEST
This test allows the operator to verify that the auxiliary inputs used for motor modulation feedback and remote Run/Hold contact closure are functioning properly. A variable voltage source, 5VDC, is required for testing.
With tSt9 displayed, press and hold the DOWN key, then press the SCROLL key. The Auxiliary input voltage will be displayed to the nearest hundredth of a volt. Connect the +5V source across the Auxiliary input terminals (terminals 8 and 5) and adjust the supply up and down to verify that it changes on the display. The displayed voltage should typically be 0-5VDC +/- 0.3 volts. To terminate the test, press the SCROLL key. The display will show tSt9. Test 9 can be initiated again or another may be selected. The existence of the auxiliary inputs tested in Test 9 depends upon the hardware configuration.
5.3.10 TEST A COMMUNICATION HARDWARE TEST (Communications Option)
This test allows the operator to verfiy that the communications hardware is functioning properly.
PAGE 55
With tStA displayed, press and hold the DOWN key then press the SCROLL key. The display will indicate SEnd. Each time the DOWN key is depressed, the unit will toggle between SEnd and rEC (receive). With the desired function selected, depress the SCROLL key. The unit will perform as described below.
In the SEnd (send or transmit) mode, the unit will repeat the following sequence. First it will enable the transmitter and put a logic 1 on the line for one second. Second, with the transmitter still enabled, it will change the logic level to 0 for one second. Third, it will disable the transmitter for one second. In the rEC mode, the unit will have its transmitter continuously disabled. In either mode, the unit will monitor the line and display rEC1 or rEC0 when it senses a logic 1 or 0 on the line respectively. In the SEnd mode, the unit will display rEC when the transmitter is disabled.
To perform an internal test and verify the basic operation of the hardware, place the unit in the SEnd mode and verify that the display cycles through rEC1, rEC0 and rEC. To verify that the transmitter functions properly, two LED''s, each with a current limiting resistor, can be connected to the communications terminals, with their polarities connected oppositely, and it should be observed that the following states are produced: one LED on, then the other LED on, then both off. Alternately, a load resistor can be placed on the terminals and it can be observed that the voltage generated across the load resistor is as follows : >+3 VDC, then >-3 VDC, and then 0 VDC.
Another method, which would also apply to an applications network, would be to connect one or more units in the Receive mode to a first unit in the Send mode. All of the units in the Receive mode should have their display alternating in sync with the first unit which is in the Send mode. When the sending unit displays rEC, the receiving units should display rEC1. To terminate the test, press the SCROLL key for one second. Upon exit, tStA will be displayed. Test A can now be initiated again or another test selected.

Trouble-shooting and Diagnostics 5.4
This section consists of two columns. The first column is a list of some possible instrument conditions. The second column is a list of steps that should improve the condition. The steps should be performed in order until the condition improves or all the steps have been com­pleted. If the instrument condition has not improved, contact the nearest representative or factory for assistance.
Trouble-shooting should be performed by qualified personnel using the proper equipment and following all safety precautions. Whenever possible, the trouble-shooting should be accomplished with the electrical power disconnected. The instrument contains static sensitive components so care should be taken to observe anti-static procedures.

Appendix B Glossary
Assured Soak
Assured Soak refers to the ability of the instrument to be programmed to interrupt the Soak segment time down if the process value exceeds a deviation value selected in the Profile Entry mode from the setpoint. The Soak timer will restart from where it was stopped when the process value does not exceed the deviation value selected from setpoint.
Automatic Reset (Integral)
This parameter is used so that the instrument will compensate for process variable deviations from setpoint that occur when the process load characteristics change. Instructions for determining the automatic reset settings are given in Section 4.3 (page 44). Factory default is
0.0. Display code ArSt.
Automatic Transfer
This feature, if configured, allows manual control of the process until setpoint is reached, at which point the controller automatically transfers from manual to automatic control. Factory default value is 0 = no auto transfer. Display code AtFr.
Balanceless Transfer
This feature prevents changes in proportional output when changing from the Manual to Control mode of operation. When transferring from the manual mode to the control mode, the proportional outputs will be "Balanceless" regardless of whether the unit is inside or outside the proportional band. This only holds true if the Auto Reset (ArSt) value is greater than 0.
PAGE 67
Bumpless Transfer
This feature prevents step changes in proportional outputs when changing from
manual control only
Control Algorithm
A pre-programmed series of instructions that are used by the instrument when determining the status of the output(s).
Cycle Time
This Tune mode parameter is used to select the on/off cycle time for time proportioning outputs (Ct1 for Output 1 and/or Ct2 for Output 2).
When using the Position Proportioning option, Ct1 must be selected for the stroke time of the motor.
Display Filter Factor
This parameter is adjustable from 1 to 20 which represents the number of scans of the process variable that are averaged together before updating the displayed value. The factory default value is 1 = no filtering. Display code dFF.
Engineering Units Upper and Engineering Units Lower
These Program mode parameters are used with volt, millivolt, and milliamp inputs. The Engineering Units Upper Euu should be selected as the value to be displayed when the input is at maximum. The Engineering Units Lower EuL should be selected as the value to be displayed when the input is at minimum.
.
automatic to
First Output Position
This parameter is adjustable from -1000 to 1000 units and represents a shift or offset of the on-off actuation points or proportional band for the first output relative to the normal position. For example, a negative value could be used to offset an expected overshoot. First Output Position also shifts the proportional band with respect to the process value range outside of which integral action is inhibited. Factory default is 0. Display code FoP.
PAGE 68
Hysteresis
This parameter is adjustable from 0 to 300 units representing the width of the band (half above and half below setoint). Used with On-Off or Alarm outputs to reduce cycling. For instance, with a value of 4 and a setpoint of 70, the output will turn On when the process variable drops to 68 and stay On until 72 is reached, then turn Off the output. Factory default is 3. Display code is HySt.
Input Correction
This parameter is used to adjust the process variable value to compensate for sensor errors. This Program mode parameter is selectable from -300 to +300 degrees/units. The factory default is 0. Display code is iCor.
Manual Reset
This parameter is adjustable from -1500 to 1500 units representing a manual shift of propor­tional band(s) relative to the normal position. Manual reset is intended to be used when automatic reset is not used to allow compensation for deviations from setpoint which remain after the process has stabilized. Factory default is 0. Increasing the value increases the process variable, i.e. if the process variable stabilized too low, increase the manual set. Integral action, and conversely reset-windup inhibit apply over the same process value range regardless of the manual reset value. Display code rSEt.
Position Proportioning Sensitivity A percentage of the first output proportional band width (Pb1).
Process Filter Factor
This Program mode parameter is used to dampen the process value used to calculate output action. The process value is averaged to dampen the control outputs. This parameter is adjustable from 1 to 20. Factory default is 1. Display code PFF.
Process Retransmission Output (EO Software Option)
Allows retransmission of the process variable. Factory default is 0 = not selected. Display code Pout. If selected, must be assigned to a current output and scaled using Process/ Setpoint upper and lower values.
Process/Setpoint Output Upper and Lower Values (Used in conjuction with process or setpoint retransmission output)
These parameters specify the process or setpoint value range over which the assigned current output will vary in a linear manner from 100 % to 0 %. If the process value or setpoint is greater than Pou the output will be 100%. If the process or setpoint value is less than PoL the output will be 0%. Factory default values are 2000 for the upper value and 0 for the lower value. Display codes Pou (upper) and PoL (lower).
Process Variable
The process variable refers to the condition of the process being measured (sensed). The instrument will accept process inputs other than temperature (pressure, level, flow, etc.).
Proportional Band (PB)
This Tune mode parameter selects the span of the proportional output range. This parameter is adjustable from 1 to 3000 degrees/units. Factory default is 100. If Output 1 is selected as a proportional output, a display code of Pb1 will be seen. If Output 2 is selected as a propor­tional output, the display code will be Pb2.
Ramp
A Ramp is the section of profile segment where the setpoint value is being changed from the initial value to the value selected over the time period selected. The first Ramp of a profile will take the process value at the time the profile was started as the initial setpoint value.
Rate (Derivative)
This parameter is adjustable from 0.0 to 10.0 minutes and specifies how the control action responds to the rate of change in the process variable. For example, if the process variable is rising rapidly to setpoint, power is turned off sooner than it would be if the rise were slow. In effect, derivative action anticipates lags within the system and shifts the proportioning band by an amount determined by the rate of change of the input sensor. Magnitude of the shift is determined by a derivative time constant. If the time constant is, say, .1 minute (6 seconds), for every unit per second rate of change of the process variable at the sensor, the proportion­ing band is moved 7 units in the direction that helps control. Likewise, if the time constant is 1 minute (60 seconds), for every unit per second rate of change of the process variable at the sensor, the proportioning band is moved 60 units in the direction that helps control. Instruc­tions for determining rate is given in Section 4.3 (page 44). Factory is 0.0. Display code
rAtE.
Rate of Change (EO Software Option)
This parameter is used to provide ramp changes based upon a selectable rate of change. Degrees per hours, minutes, seconds.
Second Output Position
This parameter is adjustable from -1000 to 1000 units and represents a shift or offset of the on-off actuation points or proportional band for the second output relative to the normal position. A positive value creates a gap where no control outputs are on, a negative value creates an overlap of control outputs (if the first output position is at the normal position). Second Output Position also shifts the proportional band with respect to the process value range outside of which integral action is highlighted (reset-windup inhibit). Factory default is
0. Display code Sprd.
PAGE 69
Segment
A segment refers to a part of a profile. A segment consists of a Ramp and a Soak section.
Setpoint Re-Transmission Output (EO Software Option)
Allows for re-transmission of the setpoint value. Factory default is 0 = not selected. Display code Pout. If selected, must be assigned to a current output and scaled using Process/ Setpoint upper and lower values.

Appendix F Profile Development Sheet
The Profile Development Worksheet is intended to assist the Profile Controller customers. By filling in the worksheet with the application requirements, profile information can easily be obtained for entry into the instrument. The worksheet is a convenient record of the profile for future use.
A profile is a programmed sequence of setpoint changes over a period of time (or at a rate of change with the EO option) (Ramp) and a constant setpoint (Soak). A sequence of a ramp and a soak is referred to as a Segment. A profile can contain from 1 to 6 segments. The instrument can store in memory up to 8 profiles.
The profile controllers can provide timed output relay action while running a profile, this is called an Event. Events may be selected as on or off as needed during each Ramp and/or Soak segment of the profile.
The first step to completing the worksheet is to determine the range of the setpoints necessary for the application. Fill out the setpoint scale along the left side of the worksheet. Remember that the profile ramp will start at the process value indicated when the profile is initiated.
The next step is to sketch the profile outline on the worksheet. Use the setpoint scale to determine the setpoint level. Be sure to fill in the time periods for each part of the segment in the boxes provided at the top of each column. The Ramp and Soak time boxes are located at the top of each column below the setpoint box for the segment. There are boxes at the bottom of each column to indicate the status of events, if used. If more than six segments are needed for the profile, individual profiles can be linked to preform sequentially. Linked profiles operate like one long profile.
Profile program information is easily determined by completing the Profile Developmental Worksheet (page 78) for the application. The information derived within the worksheet is directly related to the profile entry parameters of the profile controller.
