Product Description 1.1

1.1.1 GENERAL

The instrument is a microprocessor based circular chart Recording Profile Controller capable of measuring, displaying, recording and controlling a variety of inputs. Applications include temperature, level, pressure, flow and others. The instruments can be specified as either a single or as a dual pen model. The second pen can be selected as a profile control or a single setpoint control.

Recording, control functions, alarm settings, profile entry and other parameters are easily entered via the keypad. All user data can be protected from unauthorized changes by the Enable mode security system, and is protected against memory loss, as a result of AC power outage, by battery back-up.

The process sensor input for each terminal block is user configurable to directly connect to either thermocouple, RTD, mVDC, VDC, or mADC inputs. Changes in input type can easily be made by the user. Thermocouple and RTD linearization, as well as thermocouple cold junction compensation, are performed automatically. The instrument process variable inputs are isolated. An isolated 24 VDC regulated transmitter power supply can be provided in the instrument for use with up to two 4 to 20 mADC process sensor transducers.

The instrument can be ordered to operate on either 115 VAC or 230 VAC power at 50/60 Hz. The 230 VAC option includes a switch for selecting either 230 VAC or 115 VAC operation. The instrument is housed in a structural foam enclosure suitable for panel or surface mounting.

The number of keys and LED's will depend upon the configuration of individual unit.

1.1.2 RECORDING

The instrument records the selected process variable on a 10-inch circular chart. One box of standard charts is provided with each recorder. Charts are available in a wide selection of ranges. Chart rotation speed is programmable from 0.1 to 999.9 hours per revolution in 0.1 hour increments. The instrument can be ordered with one or two pens. Pen 1 is red and Pen 2 is green. Pens are the disposable fiber-tip type.

1.1.3 DISPLAYS

Each instrument is provided with a digital display and status indicator for each pen provided (See Figure 1-1, page 5). The display may be configured to display the Process Value, Process Value and Setpoint, Deviation from Setpoint only, Deviation and Setpoint, or Setpoint only. During configuration the display(s) is/are used to show the enabled modes of operation and the parameter codes.

The display in the upper right corner is for Pen 1, the display in the lower right corner is for Pen 2 (if provided). The upper display includes status indicators for Manual mode operation, Output 1, Output 2 , Alarm, Setpoint, negative value, degrees C, degrees F, engineering units, Ramp, Soak and Six segment lamps. The lower display (if provided), includes status indicators for Manual mode operation, Output 1, Output 2, Alarm, Setpoint, negative value, degrees C, degrees F, and engineering units. (Relative Humidity will be indicated in engineering units). See Figure 1-2 ( page 7).

Display resolution is programmable for 0.1 or 1 degree for thermocouple and RTD inputs, and none, one, two or three decimal places for other input types. Relative Humidity will be indicated as whole number only.

1.1.4 CONTROL

The instrument can be provided with relay, solid state relay driver and milliamp DC outputs. Instruments can be programmed for on-off, time proportioning, current proportioning or position proportioning control depending upon the output(s) present. Relay(s) and Solid State Relay Driver(s) may be assigned to be On or Off during the profile ramp and soak of a profile segment. Switching between the Control mode and the Manual mode of operation is easily accomplished with a dedicated key on the keypad. Switching is bumpless from the Control to the Manual mode, and while in manual, manipulation of proportional outputs is possible. Each pen of a dual pen recording controller is provided with its own AUTO/MANUAL key . Other standard control features include proportional control output limits, setpoint limits, anti-reset windup and a unique Automatic Transfer function. If configured, the Automatic Transfer function allows manual control of the proportional output until the process reaches the setpoint at which time the instrument will go into the Control (automatic) mode of operation.

1.1.5 ALARM

An Alarm indicator is standard for each pen. Two alarm functions are provided for each pen and the alarm indicator will light if either alarm for that pen is On. Alarm settings are programmable. Alarm type may be selected as process direct or reverse (high or low), deviation from setpoint direct or reverse, and deviation band open or closed within the band. Alarm outputs can be provided by assigning any relay(s) Single Pole/Single Throw (SPST)or Solid State Relay (SSR) driver to the respective alarm.

1.1.6 PROCESS VALUE RE-TRANSMISSION OUTPUT

If an instrument is specified with mADC current output(s), any of the outputs may be programmed to operate as a process value re-transmission output. The output is scaleable but can not be used as a control output while assigned as a process value re-transmission output.

1.1.7 DIGITAL COMMUNICATIONS

The instrument can be ordered with a Digital Communications option that provides the capability of bi-directional communications with a supervisory computer. A dual pen instrument can have an individual address selected for each pen. Refer to the Communications Protocol Manual (Form 2878) for more details regarding the communications option. This manual is included with the unit when the communications option is specified.

Preparations 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 interposed to isolate the instrument.

(Continued on next page)

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 practices 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. Each instrument should have a dedicated earth ground. Do not chain link multiple instrument ground wires.

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.

2.5.1.3 WIRE ISOLATION/SEGRATION

The instrument is designed to promote proper separation of the wiring groups that connect to the instrument. The AC power wire terminals are located near the top of the instrument boards. The analog signal terminals are located near the bottom of the instrument boards. Maintain this separation of the wires to insure the best protection from electrical noise. If the wires need to be run parallel with any other wiring type(s), maintain a minimum 6 inch space between the wires. If wires must cross each other, do so at 90 degrees to minimize the contact with each other and amount of cross talk. Cross talk is due to the EMF (Electro Magnetic Flux) emitted by a wire as current passes through it.

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.

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 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 that 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 soils 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)

Thermocouple lead resistance should not exceed 300 ohms. If this is exceeded, instrument accuracy could be affected.

Two wire RTD's should only be used with lead lengths less than 10 feet. If the temperature probe is to be subjected 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 mose 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

L = length of leadwire in thousands of feet.

Example A recorder 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 = 4.93 (°F/1000 ft) from Table 2. Terr = 4.93 (°F/1000 ft) Terr = 3.3 °F

RTD LEAD RESISTANCE

RTD lead length can affect instrument accuracy. Size (gauge) and length of the wire used affects lead length 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 or Table 4 is 2 wire.

L = length of leadwire 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

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 1 Terr = +/- .46 (°F/1000 ft) * 2000 ft Terr = +/- 0.92 °F

Configuration 3.1

After completing installation and wiring of the instrument the configuration (set up) procedures 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. Once properly configured the instrument will retain the user selections in memory so this procedure need not be repeated unless required by changes in the application. 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 sections referred to as modes. Each mode contains a different type of data or may be used for specific operating functions. For two pen instruments, some modes are common to both pens. These modes are as follows:

system, can lock out everything except Off and Control (See Appendix A-1, page 67, for hardware lockout information)

Associated with each mode is a series of unique displays that are accessed via the front keypad.

Prior to first time operation of the instrument, the configuration procedures for the Program and Tune modes must be performed as applicable. Calibration and Test modes are not used as part of the instrument configuration or operation. These are used for service and maintenance functions and are discussed in Section 5.4 & 5.5 of this manual (page 56 - 66).

Shipped Configuration/Jumper Positioning 3.2

Each instrument is factory shipped ready to accept a thermocouple input on TB 4 and TB 5. All parameters in each mode are set to default values. These defaults are shown in tabular form after the description for each mode. Instrument AC power input is as specified in the instrument model number and is shown on the ratings label. The 230 VAC option includes a switch in the instrument for selecting either 230 VAC or115 VAC input power. If this feature is provided, verify AC input and switch position before applying power to the instrument.

3.2.1 JUMPER POSITIONING

Jumpers are used to condition the sensor inputs and to provide a security lockout feature. All jumpers are located on the instrument Processor board. The instrument board layout and jumper locations and functions are shown in Appendix A-1 (page 67). Check the jumper positions in the instrument and verify that they are in the proper position for the intended application.

The sensor input jumpers JU4, JU5, JU6 and JU7 condition the sensor input signals and must be used in conjunction with input type selections made in the Program mode. (page 28).

Operation Summary 3.3

3.3.1 MODE SELECTION

If the instrument is either in the Off mode or the Control mode, repeated pressing and releasing of the SCROLL key will cause the instrument to display the code corresponding to each mode that is enabled. To enter a mode while the code is displayed, press the DOWN key. If a mode does not appear, refer to the Enable mode section for information on how to determine if the mode is on.

Entry into any mode except the Control, Tune, Manual and Enable modes, will cause the output(s) to turn off and any process re-transmission value output(s) to be 0 %.

Start up Procedures 3.4

All configuration parameters are listed in Tables 3-1 through 3-4. For a single pen instrument, parameters for each mode are displayed in the upper right

display. If the instrument being configured is a two pen model, a sequence of applicable parameters will be displayed in the Pen 2 display after the Pen 1 parameters have been reviewed and configured. After the Pen 2 parameters have been completed, parameters common to both pens will be configured and displayed in the Pen 1 display.

The instrument is provided with a time out feature. If the instrument is in any mode (except while executing a calibration or test procedure) and no keypad activity takes place for 30 seconds, the instrument will time out and exit the mode automatically. The display will become the code for the respective mode. If a mode code is displayed for 5 seconds with no keypad activity, then the time out will cause the instrument to proceed to either the Control or Off mode, depending upon whether the mode entered was an operational mode (Tune, Manual, Enable) or non operational mode (Test, Program, Cal, Profile Entry or Profile Continue).

3.4.1 POWER UP PROCEDURE

Step 1 Verify that all electrical connections have been properly made before applying power to the instrument.

Step 2A - For instruments with software revision R2.99 and below Upon power up, 7XXX will be displayed (X representing digits), then XXXX, then XXXX, identifying the twelve digit model number as defined in the order matrix. Next, the EPROM part number will be indicated P-XX. After the EPROM part number, the software revision level will be displayed in the format rX.XX then tSt1, tSt2, tSt3 will be displayed while Test 1 through 3 are executed automatically. Upon successful completion of these tests, CtrL or oFF will be displayed for about three seconds. The mode displayed will be the mode that the instrument was in when the power was turned off. During this time the operator may select another mode (Tune, Manual, Enable) or non-operational mode (Test, Program, Cal).

Step 2B - For instruments with software revision R3.00 and above Upon power up, a brief flash on all displays (upper and, if equipped, lower) will occur to show the instrument is "alive". Then 7XXX will be displayed (X representing digits), then XXXX, then XXXX, identifying the twelve digit model number as defined in the order matrix. Next, the EPROM part number will be indicated P-XX. After the EPROM part number, the software revision level will be displayed in the format rX.XX followed by P.dn (if Pen Action on Power Up, PAPu, in Program Mode is set to 0, pens go to "home" position on power up). During this display, the decimal point after the "P" will blink to show the mode is active. Upon successful completion of this routine, CtrL or oFF will be displayed for about three seconds. The mode displayed will be the mode that the instrument was in when the power was turned off. During this time the operator may select another mode (Tune, Manual, Enable) or non-operational mode (Test, Program, Cal).

Step 3 If any error messages are displayed, refer to Section 5.6 (page 60) for a definition of the error message and the required action.

Front Panel Operation 3.5

3.5.1 DIGITAL DISPLAY AND STATUS LED’S

The digital display provided for each pen 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;

MAN Amber Lights when the Manual StbY mode is on. OUT1 Red Lights when Output 1 is on or mADC output selected. OUT 2 Amber Lights when Output 2 is on or mADC output selected.. ALRM Red Lights when either Alarm is on. C Red Lights to indicate that the process value is in degrees C

(Celsius).

Operation 4.1

4.1.1 OFF MODE

In the Off mode, the instrument control and alarm function (s) are turned off. Process Retransmission signal(s) remain active. The chart rotation can be selected in the Program mode to stop or continue to rotate when the instrument is in the Off mode. The pen(s) will remain active. 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 current process variable at two second intervals. Entering the Off mode of a dual pen instrument will cause both pens to enter the Off mode. The second pen display will be blank as the upper display reads oFF and displays the process value for the second pen at the same time as the upper display.

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 and the chart will be rotating at the rate selected. The Control mode allows setpoint changes form either local setpoint (standard) adjustment by an operator at the front keypad or from remote setpoint source (optional). Other operations in the Control mode include a lamp test and proportional output display.

4.1.2.1 LOCAL SETPOINT OPERATION

Single Pen Instruments: The instrument must be in the Control mode to allow setpoint value to be displayed and adjusted. In the Control mode, to view the setpoint, press and release the UP and 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. If the setpoint will not increase, check the Program mode to see that you are not trying to increase the setpoint above the setpoint upper limit SPuL. If the setpoint will not decrease, check the Program mode to see that you are not trying to decrease the setpoint below the setpoint lower limit SPLL. If the setpoint will not increase or decrease, check that the Setpoint Change mode is On in the Enable mode.

Dual Pen Instruments: The setpoint of each instrument can be reviewed separately. Pen 1: To review and change the local setpoint for Pen 1, press the UP key. The green LED in the upper display will light indicating that the setpoint value is displayed. The setpoint can now be raised by pressing and holding the UP key or decreasing by pressing the DOWN key. Pen 2: The setpoint for Pen 2 is viewed and changed in the same manner, except the DOWN key must be pressed to access the Pen 2 setpoint. The setpoint will change slowly at first, then faster as the key is held. If the setpoint will not increase, check the Program mode to see that you are not trying increase the setpoint above the setpoint upper limit SPuL. If the setpoint will not decrease, check the Program mode to see that you are not trying to decrease the setpoint below the setpoint lower limit SPLL. If the setpoint will not increase or decrease, check that the Setpoint change mode is On in the Enable mode.

4.1.2.2 REMOTE SETPOINT OPERATION (OPTIONAL)

Dual Pen Instruments: The Remote Setpoint Option is only available on the second pen of a dual pen instrument. To use this option, if available, the Program mode selections must be properly made. The Remote Setpoint parameter rSP must be selected as a 1 or 2 as needed. The Remote Setpint Upper rSPu and Lower rSPL parameters need to be selected for the application. Pen Profiling Configuration parameter PPC must be selected as 1 Pen Profiling only. The Remote Setpoint signal is connected to the TB5 terminals as whon in Section 2 of this manual.

Digital Communications: The setpoint can be adjusted from a supervisory computer system. Dual pen instruments are capable of having independent setpoint adjustments for each pen.

4.1.2.3 PROFILE CONTROL OPERATION

To start a profile, press and release the SCROLL key until the number of the profile that is to be started is displayed. 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 second to indicate that the profile is starting. The status lamps will indicate which segment is active and if in the ramp or soak portion of the segment.

To stop a profile that is running, press the RUN/HOLD key. The display will who 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, 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 will CtrL displayed will abort the profile and begin controlling the process automatically at the last setpoint value. Event outputs remain in the state (on or off) that they were in prior to aborting 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 configured 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 PSCt 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 the start can be accomplished by using the Profile Continue mode. Press and release the SCROLL key until the display is PCon, then press the DOWN key. The display will be Pn, adjust the profile parameter values as needed in the Profile Continue Configuration mode, then press the RUN key. The instrument will execute the profile selected as directed by the information entered in the Profile Continue mode. The parameter values seen in the Profile Continue mode will indicate the values of the last active profile.

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 for each pen. 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 on each pen. This adjustment is in terms of degrees/engineering units and defines the width of the hysteresis band about the setpoint. This parameter may also be referred to as a deadband. 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 for the respective pen will illuminate to indicate that the output device is On.

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 programed for output 1 and/or 2 for each pen. 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 4-20mADC 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.

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 for the respective pen. This control implementation can be performed on each pen.

Position 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 will be 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 % required to correct for the deviation between setpoint and process.

Proportional Output 1 Action P1EC on error condition does not apply to position proportioning control. In an error condition, the unit goes only to 0% output (fully closed).

With Position Proportioning control, it may be necessary to adjust the Sensitivity Tune SEnS 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 controller will move the motor for the proper amount of time when making adjustments.

4.1.2.8 PROPORTIONAL OUTPUT PERCENTAGE DISPLAY

While in the Control mode, pressing the UP and the SCROLL keys at the same time will cause the display to sequence through a series of display codes and values:

Po1 Percent Output (if applicable) Output 1% value Po2 Percent Output (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. Displays will sequenced for both Pen 1 and 2 as applicable on dual pen instruments.

4.1.3 MANUAL MODE FOR PROPORTIONAL OUTPUTS

Manual adjustment 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 occurrence of certain error conditions.

Note: The proportional outputs 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 AUTO/MAN key for the specific pen. If the Standby mode is On in the Enable mode and a control output is selected for proportional control, the instrument will enter the Manual mode. The Manual mode status LED will light for that pen 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.

In order to vary a proportional output value, press and release the SCROLL key until the display code for the output is displayed, Po1 or Po2. Press 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.

If no keys are pressed, the display will sequence through the following displays:

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, 7 then the output 2 percentage of output value

Proc will be displayed then current process value for that pen

In order to change a proportional value once the cyclic display begins, press and release the UP or DOWN key then press the SCROLL key until the display code for the output displayed is Po1 or Po2. Press 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 specified AUTO/ Man 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.

Alarm Operation 4.2

There are two alarms available per pen. 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 than 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. Deviation Alarm Reverse - the alarm will be On if the process value is less than the setpoint plus the deviation 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 Close 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 alarms will be active while the instrument is in the Control mode. Relay and solid state relay drivers can be assigned to provide output capability for the alarm functions.

The alarm value (Process deviation or bandwidth) is selected in the Tune mode. Alarm outputs chatter can be reduced by using the hysteresis for the alarm output adjustable

in the Program mode to create a deadband around the alarm point.

Tune Mode Operation 4.3

Proportional output controllers 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 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) at the factory default settings. Obtain the best possible process reaction by adjusting the Proportional Band width 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 78).

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 for the best possible proportional band adjustment), Manual Reset may be added to eliminate this offset.

8. Auto Reset may be added to eliminate process offsets with respect to setpoint. Increase Auto Reset from 0 to 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 to any changes.

9. If necessary, Rate may be added. Rate is a dynamic tuning parameter. Rate may be required to compensate for load changes or to inhibit process oscillations that occur when a large amount of auto reset (4 or 5 repeats/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 ideal 1/4 amptitude decay tuning parameters that are determined by watching the system in a sustained oscillation (curve C, page 44, the ultimate proportional band and ultimate time period) and then using these values from this sustained oscillation to calculate ideal parameters.

To aid in determining the process oscillation, the instrument configuration parameters can be adjusted. By reducing the chart upper value Cru and increasing the chart lower value CrL, the resolution of the oscillation can e better observed. Also the chart rotation time Crt can be reduced to improve the observation of the oscillation cycle time.

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.

4. Achieve a response curve similar 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 over damped response is desired, multiply the proportional band by two.

In the rEC (receive) mode, the transmitter is continuously disabled. In either mode, the instrument will monitor the line and display rEC1 when a logic 1 is on the line or rEC0 when a logic 0 is on the line . In the SEnd mode, the instrument will display rEC when the transmitter is disabled. To perform an internal test and verify the basic operation of the hardware, place the instrument 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 with opposite polarity observed to the TB 2 terminals 1 and 2. The following three states should be observed: one LED On, then the other LED On, then both Off. Alternately, a load resistor can be placed on the terminals, and observe that the voltage generated across the load resistor is as follows: >+3 VDC, then >-3 VDC, and then 0 VDC.

Another method, to test the communications hardware, would be to connect one or more instruments in the Receive mode to an instrument in the Send mode. All of the instruments in the Receive mode should have their displays alternating in sync with the instrument in the Send mode. When the sending instrument displays rEC, the receiving instruments should display rEC1. To terminate the test, press the SCROLL key for one second. Upon exit, tStA will be displayed. The existence of the communications hardware is dependent on the

hardware configuration.

Appendix B Glossary

Assured Soak

The instrument may be programmed to interrupt the Profile Soak segment if the process value exceeds a selectable deviation from setpoint value. The Profile 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 48). 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.

Bumpless Transfer

This feature prevents step changes in proportional outputs when changing from automatic to manual control only.

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 usng 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 per second of the process variable that are averaged together before updating the displayed and recorded 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.

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.

Hysteresis

This parameter is adjustable from 0 to 300 units representing the width of the band (half above and half below setpoint). 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 = 3. Display code HyAo for Alarm outputs. Display code HyCo for ON/OFF Control outputs.

Input Correction

This parameter is adjustable from -300 to 300 units and is used as a method to compensate for a linear sensor error. Factory default is 0 = no correction. Display code iCi1, iCi2.

Input Correction

This parameter is adjustable from -300 to 300 units and is used as a method to compensate for a linear sensor error. Factory default is 0=no correction. Display code iCi1 and iCi2.

Manual Reset

This parameter is adjustable from -1500 to 1500 units representing a manual shift of proportional band(s) relative to the normal position which is an even strattle of the setpoint. 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 stabilizes 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.

Pen Action on Power Up

This parameter specifies whether the pen, on a power-up will drive to the "Home Position" (center of chart), then return to its correct postion. This is done as a cal check. Settings are 0=go to "home" and 1=remain in last position prior to power down. Default is 0.

Platen

The flat surface in the instrument upon which the chart rotates.

Position Proportioning Sensitivity

A percentage of the first output proportional band width (Pb1).

Process Filter Factor

This parameter is adjustable from 1 to 20 which represents the number of scans per second of the process variable that are averaged together before updating the process value used for control purposes. The factory default value is 1 = no filtering. Display code PFF.

Process Retransmission Output

Allows re-transmission 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 Output upper and lower values.

Process Output Upper and Lower Values (Used in conjunction with process retransmission output)

These parameters specify the process value range over which the assigned current output will vary in a linear manner from 100% to 0%. If the process value is greater than Pou the output will be 100%. If the process 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 Rounding

This parameter is adjustable from 0 to 100 units and is used to round the process value to the nearest value specified. This is for display only and does not affect the recorded value or control action. Intended for use where the engineering units span is large, to reduce display fluctuation. Factory default is 0 = no rounding. Display code Prnd. (e.g. Prnd = 3, Process

Value = -6, -3, 0, 3, 6, 9....)

Proportional Band (PB)

This parameter is adjustable from 1 to 3000 units (not Percent of span) and represents the process value range where the proportional output is at a percentage of the full output. Instructions for determining Pb are given in Section 4.3 (page 48) . Factory default is 100 units. Display code Pb1 and Pb2.

Ramp

A Ramp is the section of a 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 proportiong 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. Factory default is 0.0 Display code rAtE.

Second Output Position (SoP)

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 SoP.

Segment

A segment refers to a part of a profile. A segment consists of a Ramp and a Soak section.

Soak

A Soak is the section of a profile segment where the setoint value is at a constant value for the time period selected.

Appendix F Profile Development Sheet

The Profile Development Worksheet is intended to assist the Profile Recorder 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 (Ramp) and setpoint maintained at a single point for a period of time (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 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. For dual pen profile controller be sure to scale the setpoint range for the greater range. 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 levels. Draw each profile separately on a dual pen instrument. 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 boxes 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 then 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 for the application. The information derived within the worksheet is directly related to the profile entry parameters of the profile controller.
