StarPac II Local interface Structure & Operation

The StarPac II local user interface allows complete user access to configure and calibrate a StarPac II Intelligent Control Valve System. The interface consists of a Liquid Crystal Display (LCD) and a membrane-covered keypad. The LCD is a 4 X 20 character display with the top two lines user configured for normal operation, or for displaying instructions or options during configuration. The bottom two lines are used to indicate menu options that are selected with the four function keys. To the right of the menu options, on the bottom two lines, are two normally blank spaces that indicate Alarm or Error conditions, indicated by a flashing “A” and/or “E”. A flashing “T” on the right side of the display indicates that the unit is in Test mode and will not respond to commands until the unit is set to Manual or Auto mode in the T

The keyboard has three types of keys; the menu control keys (which consist of the LAST OPTION, F1, F2, F3, and F4 keys); the alphanumeric keys; and the colored shift keys. The F1, F2, F3, and F4 keys refer to the menu options listed in the LCD of the interface. The LAST OPTION key is used to move back through the menus. The alpha-numeric keys are used to enter data requested in various options. The red, blue and green shift keys are used to select the corresponding colored letter on the alpha-numeric keypad.

UNE menu.

The various menu options have three basic forms. The first type is a list that is scrolled through by using the F1 and F2 keys labeled NEXT and PREVIOUS. The second type uses the F1 and F2 keys to adjust a value up or down, and the third type uses the F1 and F2 keys to move the cursor to a position. The keypad is used to enter characters. In all of the options, the F3 key is used to cancel the operation. If the F3 key is pressed before the system returns to the menu, then all variables are returned to their old values. The F4 key is used to accept the current values in the display and continue.

Manu Posn Status

The HOME menu has selections of STATUS, TUNE, CALIBRATE, and

ONFIGURE. Each of these menus has several sub-menus. The

C bottom two lines define the function keys that control the individual menus. The top two lines in the display are user configurable and may not look like Figure 1.

If you see the word ‘Next,’ then push the F4 button to bring up the continuation of that row. To move back up the menu tree, push the button labeled ‘Last Option’ to see the preceding row.

Initial Startup

The StarPac II system is designed to interface with a variety of DCS systems using analog, discrete, and digital communications. Because of the processing power of the StarPac II system, a separate 24 VDC power connection is required and connected to terminals 16 (-) and 17 (+). This power supply should have a minimum current capacity of 300 mA.

Before powering up the unit - Read the section “Setting the System Jumpers” and set them according to the instructions and particular application.

Powering up the unit on the bench - When the unit is first powered up, the display will show the version number of the firmware for two seconds before beginning operation. The StarPac II system sensors are calibrated at the factory and the fluid data is entered as specified on the order. However, due to the differing nature of installations, the units and ranges of the analog and discrete I/O are not configured at the factory.

The suggested process for setting up a new system on the bench is:

1. In the CONFIGURE menu, select the engineering units you will be using.

2. If you will be using analog I/O signals, use the CONFIGURE menu to set up the analog channels to indicate the proper process variables and ranges you will be using. Note that the StarPac II system treats gas flow and liquid flow as different variables and they must each be specified correctly.

3. Connect the instrument air supply (40-150 psi) to the ¼-inch NPT air supply port located on the back of the unit.

4. Use the STATUS menu and set the Row Two variable to “valve position.”

5. Use the TUNE menu to put the unit in to Manual mode with a digital command.

6. Using the “Command %” option in the TUNE menu, enter a 0 percent command and verify that the position follows to within 0.5 percent. Note: Command is a term with two meanings. For a traditional control valve, the command is the signal a controller sends to the I/P. position the stem. For the StarPac II, this meaning refers to the signal sent to the positioning module. When the StarPac II is in Manual mode, Command also refers to the signal sent to the StarPac II via analog input No. 1, a digital Modbus channel, or the front keypad. These commands may differ due to the internal stroke calibration and an inverted signal for air to close valves.

7. Using the Command % option in the T percent command and verify that the position follows to within 0.5 percent.

8. If the unit fails either of the tests above, perform a Stroke

calibration in the C

9. Use the STATUS menu and set the Row Two variable to be “ISA upstream pressure.”

10. Verify that the unit is correctly indicating the ambient pressure.

11. Use the S “ISA downstream pressure.”

12. Verify that the unit is correctly indicating ambient pressure.

13. If the unit fails the above tests, re-zero the transducers using the P1 & P2 option in the C need to pressurize the sensors and verify the Span if the calibration is suspect.

14. Use the S “process temperature.”

15. Verify that the unit is correctly indicating ambient temperature.

16. If the unit fails the above test, re-calibrate the transducer using the thermocouple option in the C calibration requires a Type-K thermocouple simulator or a temperature bath.)

17. Use the CALIBRATE menu to check the analog channels that you will be using.

18. Finally, use the TUNE menu to select the process variable

that you will be controlling and set the range.

Putting the Unit on line - After installing the unit, use the TUNE menu to configure the setpoint signal to the proper source for your DCS system. If you will be using the system in the Automatic mode, adjust the Proportional-Integral-Derivative (PID) parameters so the loop responds satisfactorily.

Backing up the system - When you have your unit calibrated and working according to your needs, back up the configuration into the safe memory area. This is done in the Save Backup choice in the Tech option of the C

Alarms - Allows the user to view any current alarms using the NEXT or PREVIOUS function keys. Possible alarms are:

Setpoint Deviation - The controller is unable to maintain the process at the current setpoint. (Sensitivity is adjusted using StarTalk software.)

Positioner Deviation - The positioner is unable to maintain the valve position at the current command. (Sensitivity is adjusted using StarTalk software.)

Trip Condition - The unit is in a trip condition of either loss of command, low supply air, or a low flow cutoff. Low flow is determined when the pressure drop across the valve is less than

0.5% of the calibrated range of the pressure sensors. (Use the Row 1 Variable M

ODE/STATUS menu selection to display the type

of trip.) Override Condition - Indicates the controller is not currently

capable of doing any more to achieve the setpoint (or valve position). This can be any of the trip conditions, or a mechanical or software travel limit has been reached and the controller has exceeded the 5 percent current limit.

Sensor Malfunction - One of the sensors has a suspect output. (See sensor errors for detail.)

Device Malfunction - The electronics has an internal error. (See device errors for detail.)

Sensor Errors - Allows the user to view any current sensor errors using the NEXT or PREVIOUS are:

function keys. Possible sensor errors

Upstream Pressure - The output of the upstream pressure sensor is out of range.

Downstream Pressure - The output of the downstream pressure sensor is out of range.

Cylinder Top Press - The output of the top actuator pressure sensor is out of range.

Cylinder Bot Press - The output of the bottom actuator pressure sensor is out of range.

Process Temperature - The output of the process temperature sensor is out of range.

Ambient Temperature - The output of the ambient temperature sensor is out of range.

Position Feedback - The output of the position feedback sensor is out of range.

Device Errors - Allows the user to view any device errors using the NEXT or PREVIOUS

function keys. Possible device errors are:

Watch Dog Timeout - The CPU had an interruption in the execution cycle. This is sometimes caused by momentary power interruptions. However, if it persists, this is a serious error usually requiring hardware replacement. This error can only be cleared by turning off the device and then turning it on again.

SRAM R/W Failure - The static RAM had an error. This is a serious error usually requiring hardware replacement if it

persists. This error can only be cleared by turning off the device and then turning it on again.

EPROM Checksum Error - Check the integrity of the firmware. This error usually occurs when the firmware is changed and can be cleared with an initialization. (This is done by holding down the “0” on the keypad while powering up the unit.

Warning: An initialization will also reset the communication parameters, password, and PID control parameters.

NVRAM R/W Failure - The non-volatile RAM had an error. This is a serious error usually requiring hardware replacement if it persists. This error can only be cleared by turning the device off and then turning it on again.

Thermocouple Burnout - The thermocouple junction is open. Check interface connections, thermocouple, and/or wire.

A/D Failure - One of the A/D converters is not working correctly. If slowly cycling the power does not clear the error, then a hardware replacement is necessary.

Vcc Out of Tolerance - An internal power supply is operating out of tolerance.

V- Out of Tolerance - An internal power supply is operating out of tolerance.

V+ Out of Tolerance - An internal power supply is operating out of tolerance.

Illegal Pointer - One of the configurable arrays is using an invalid register.

NVRAM Checksum Error - A value in the non-volatile RAM was changed without resetting the checksum. Performing any write function, such as a setpoint or command change should reset the error. If the system behaves erratically after receiving an error, the NVRAM may have been corrupted and you should reload the factory configuration table from the disk provided using the StarTalk for Windows software.

Divide by Zero - The StarPac II unit attempted an illegal math operation due to bad calibration or configuration settings. Reload the factory configuration table from the disk provided, using StarTalk for Windows software.

Alarm Mask - Allows the user to enable or disable individual alarm functions.

Setpoint Deviation - The controller is unable to maintain the process at the current setpoint. (Sensitivity is adjusted using StarTalk software.)

Positioner Deviation - The positioner is unable to maintain the valve position at the current command. (Sensitivity is adjusted using StarTalk software.)

Trip Condition - The unit is in a trip condition of either loss of command, low supply air or a low flow cutoff. (Use the

ODE/STATUS menu selection to display the type of trip.)

Man/Auto - This option selects or changes the operating mode if the mode source has been set to digital. If the mode source is set to Remote or Discrete, the mode can only be changed using the discrete input or the remote register. In Manual mode the unit operates as a normal control valve, positioning the valve according to its current command signal.

In Auto mode the unit will operate as a controller using the PID settings, process variable, and control action currently defined using a bumpless transfer algorithm. (Note that if the unit is using an analog command source, the system will bump because the 4-20 signal will change from indicating position command to process setpoint.)

Test mode takes the unit off-line and the system DOES NOT calculate pressures, temperatures, flow, or PID values; nor does it support setpoints or any analog or digital commands. Test mode is the beginning mode after an initialization and is used during calibration. If power is lost during a calibration setup, the unit will remain in Test mode and the mode will have to be reset. If the unit is in Test mode, the letter “T” will flash on the right side of the display.

Mode Source - This selects where the StarPac II unit will receive the mode information. “Digital” indicates that the keypad or the StarTalk software can be used to change the mode. “Discrete” indicates that an external signal applied to terminals 33 and 34 will be used to switch the unit between Auto and Manual modes. The definition is fixed with an energized state indicating Auto mode. Remote mode is used when a host system such as a PLC or DCS is used to set the mode via digital communications.

The difference between Remote and Digital is that if the Setpoint/command is not refreshed within a given period, the StarPac II will assume that the unit has lost communication with the host and will go to a trip condition.

Setpoint - Provides four options used to change the setpoint and configure the source of the setpoint.

Setpoint % - Allows the direct input of the controller setpoint as a percentage of maximum, as setup with the process variable, provided the unit is in the Auto mode with the digital setpoint selected.

Setpoint User Units - Allows the direct input of the setpoint in the configured engineering units, provided the unit is in Auto mode with the digital setpoint selected.

Analog/Digital

- This option selects where the StarPac II system

“Digital” indicates that the keypad or the StarTalk software can be used to change the setpoint.

“Analog” prompts the StarPac II to use the 4-20 mA signal from analog input No. 1 as the controller setpoint.

“Remote” is used when a host system such as a PLC or DCS is used to write the setpoint to the unit digitally.

StarPac II User Interface Manual 10

Remote Refresh Rate

- This option sets up a time-out on the

receipt of fresh setpoint data when set to operate with a remote setpoint. If the setpoint is not refreshed within the time frame entered in this field, the unit will go into a loss-of-command trip as set up in the C

ONFIGURE menu. A value of “0” disables this

feature and makes the electronics think that the Mode source is digital. Note that if the digital source is selected, the unit will hold at the last setpoint indefinitely.

Command - Provides three options used to change the valve position command and configure the source of the valve command.

Command % - Allows the direct input of the valve position command as a percentage of valve travel. Zero percent is closed and 100 percent is open--provided the unit is in Manual mode with the digital command selected.

Analog/Digital - This option selects where the StarPac II system will receive the valve position command information.

“Digital” indicates that the keypad or the StarTalk software can be used to change the valve position command.

“Analog” prompts the StarPac II to use the 4-20 mA signal from analog input No. 1 as the valve position command.

“Remote” is used when a host system such as a PLC or DCS is used to write the valve position command to the unit digitally.

Remote Refresh Rate - This option sets up a “timeout” on the receipt of fresh, valve-position command data when set to operate with a remote command. If the valve position command is not refreshed within the time frame entered in this field, the unit will go into a loss of command trip (as set up in the

ONFIGURE menu). A value of “0” disables this feature. Note

C that if the digital source is selected, the unit will hold at the last valve position command indefinitely.

Proportional Band - Sets the proportional band for the controller. Proportional Band = 100/gain or gain =100/prop. band. Since proportional band is the inverse of gain, the larger the band value, the smaller the controller gain.

Reset Rate - This is the integrator term in the PID controller, referring to the action at which the rate of change of output is proportional to the error input. “Reset” is the parameter that controls how the integral control action affects the final control element. The larger the value, the faster the system tries to eliminate the offset error. Units are repeats/min.

Derivative Time - Sets the time on the derivative control action of the PID controller. This time is the interval at which the rate action advances the effect of the gain on the final control element. Units are in seconds.

PID Action - This variable determines the response of the controller to error. Reverse action will cause an air-to-open valve to begin to close when the process variable is greater than the setpoint. Direct action has the opposite effect. The following table gives some guidelines for control action settings:

If the PID action is not set correctly, the controller will hold the valve either full open or full closed and there will be no control.

Process Variable Select - Selects the process variable that will be used to control the process.

Liquid Flow - Sets the system to control liquid flow. (If the flow is gaseous, the system will read the liquid flow value as zero and respond accordingly.)

ISA Up Stream Press - Sets the system to control using the current compensated upstream line pressure. (Defined as two pipe diameters upstream of the valve.)

ISA Dn Stream Press - Sets the system to control using the current compensated downstream line pressure. (Defined as six pipe diameters downstream of the valve.)

ISA Delta Pressure - Current differential pressure using the pressure definitions above.

Process Temperature - Sets the system to control the process temperature.

Gas Flow - Sets the system to control gaseous flow (if the flow is liquid, the system will read the gas flow value as zero and respond accordingly).

Auxiliary 4-20 Input - Sets the system to use a 4-20 mA signal attached to Analog Input 2 as the process variable.

Process Variable Scaling - This option sets the full scale process value that the controller will use in the PID algorithm, using the units that have been selected in the C Auxiliary, which is always in units of percent).

Reset Totalizer - Selecting this option resets the time and amount in the flow totalizer to zero.

menu. Actuator - This option calibrates the actuator pressure sensors in

the unit. The process requires that the valve stroke from full open to full closed. Because the valve will change position during this process you must confirm that you want to proceed. You will then be prompted for the instrument air supply pressure to the unit. If the air supply varies by more than 1 psi during the calibration, the test may abort. Hence, a regulator may be required if the air supply is not stable. The unit will then complete the calibration process by stroking the valve open and closed over 30 to 60 seconds. Upon successful completion, the display will momentarily flash the message “Calibration Successful”.

Stroke - This option calibrates the position feedback sensor in the unit. The process requires that the valve stroke from full open to full closed. Because the valve will change position during this process you must confirm that you want to proceed. You will then be prompted for the valve type; linear or rotary. If the air supply varies by more than 1 psi during the calibration, the test may abort. Hence, a regulator may be required if the air supply is not stable. The unit will then complete the calibration process by stroking the valve open and closed over one to five minutes. Upon successful completion of the process, the system will momentarily flash the message “Calibration Successful”.

WARNING: Notify personnel working nearby that the valve will stoke during this procedure; otherwise, serious injury may occur.

P1 and P2 - This option simultaneously calibrates the process pressure sensors in the unit and is the recommended sensor calibration method. Because it calibrates both sensors at the same time, this procedure automatically moves the valve’s stroke to midstroke. This calibration should always be done with the flow through

the valve blocked. If there is flow through the valve you must use

Span - Apply the maximum pressure you want to use for your reference and press ACCEPT. The two numbers on the right side of the display indicate how steady the pressure is in the valve body. Next, enter the actual pressure applied in the indicated engineering units and press ACCEPT.

Sensor Gain - This option configures the input amplifier range for the installed sensors using the Up and Dn function keys. Valtek’s standard sensors normally use the 39mV < out < 78mV selection. Normally, you should not have to change this option. If you have questions, consult your Valtek representative.

P1 - This option calibrates the upstream process pressure sensor in the unit. You will then have two more menu options to set for Zero and Span.

Zero - Apply the atmospheric pressure or the minimum pressure you want to use for your reference and press ACCEPT. The number on the right side of the display indicates how steady the pressure is in the valve body. Next, enter the actual pressure applied in the indicated engineering units and press ACCEPT.

Span - Apply the maximum pressure you want to use for your reference and press ACCEPT. The numbers on the right side of the display indicate how steady the pressure is in the valve body. Next, enter the actual pressure applied in the indicated engineering units and press ACCEPT.

P2 - This option calibrates the downstream process pressure sensor in the unit. You will then have two more menu options to set for Zero and Span.

Span - Apply the maximum pressure you want to use for your reference and press ACCEPT. The number on the right side of the display indicates how steady the pressure is in the valve body. Next, enter the actual pressure applied in the indicated engineering units and press ACCEPT.

Thermocouple - This option is used to calibrate the Type-K thermocouple temperature sensor in the unit. You will then have two more menu options to set for Zero and Span. Normally this calibration is done using a temperature controlled bath or a Type-K

StarPac II User Interface Manual

thermocouple simulator connected to terminals 5 (yellow) and 6 (red).

Zero - Apply a signal equal to the minimum temperature you want to use for your reference and press ACCEPT. The number on the right side of the display indicates how steady the temperature input is reading. Next enter the actual temperature applied in the indicated engineering units and press ACCEPT.

Span - Apply a signal equal to the maximum temperature you want to use for your reference and press ACCEPT. The number on the right side of the display indicates how steady the temperature input is reading. Next, enter the actual temperature applied in the indicated engineering units and press ACCEPT.

Positioner - This option is used to set the control gains for the positioner and also test for proper response.

Figure 6: Positioner Menu Tree

Default Gain - This option sets the default gain for the

positioner. Select the correct actuator size from the list using the NEXT and PREVIOUS function keys on the menu. Default selections exist for 25, 50, 100, and 200 square-inch actuators.

Edit Gain - This option allows you to change the gains from the default value to customize the response of the system.

Proportional Gain - Controls the overall speed of response of the system. Larger values will speed up the response of the system.

Static Gain - Controls the response to steps of less than two percent. Larger values will speed up the response of the system to small steps (the effect of static gain is more evident on larger actuators).

Error Gain - This is a dynamic gain variable that increases the gain with error size to speed the response in larger actuators. Note that smaller values increase the gain.

Step Test - Allows you to monitor the response of the system to any step size that you input after pressing the function key. (Be aware that this operation will cause the valve to stroke.) The system reports the overshoot and rise time (Tr) for each step. Pressing ACCEPT will continue to stoke the system up and down and report on the response for each step. To quit the positioner tuning press CANCEL.

Open Loop- This test is a diagnostic test to check the mechanical operation of the postioner module. During this test

StarPac II User Interface Manual 16

the valve is forced to full open and full closed by driving the positioner output to its maximum and minimum values.

WARNING: Notify personnel working nearby that the valve will stroke during this procedure; otherwise, serious injury may occur.

Puls Out

Analog Out 1 - This option configures the first analog output

channel. Select a variable from the list using the NEXT and PREVIOUS function keys on the menu. You will then be asked for a full scale output value in your selected user units. (This is the process value that corresponds to 20 mA.) The last step is to enter the offset or Zero output value in your selected user units. (This is the process value that corresponds to 4 mA.) Available output variables are:

Valve Position - Current valve position. Liquid Flow - Current liquid flow rate. ISA Up Stream Press - Current compensated upstream line

pressure (defined as two pipe diameters upstream of the valve).

StarPac II User Interface Manual

ISA Dn Stream Press - Current compensated downstream line pressure (defined as six pipe diameters downstream of the valve).

ISA Delta Pressure - Current differential pressure using the pressure definitions above.

Process Temperature - Current process temperature. Gas Flow - Current gaseous flow rate. Auxiliary 4-20 Input - Re-transmits the 4-20 mA signal from

analog in No. 2. Register Number - Allows the selection of any internal register

value as an output. If a string register is selected, zero will be displayed in the data field.

Analog Out 2 - This option configures the second analog output channel. Select a variable from the list using the NEXT and PREVIOUS function keys on the menu. You will then be asked for a full scale output value in your selected user units. (This is the process value that corresponds to 20 mA.) The last step is to enter the offset or zero output value in your selected user units. (This is the process value that corresponds to 4 mA.) Available output variables are:

Valve Position - Current valve position. Liquid Flow - Current liquid flow rate. ISA Up Stream Press - Current compensated upstream line

pressure (defined as two pipe diameters upstream of the valve). ISA Dn Stream Press - Current compensated downstream line

pressure (defined as six pipe diameters downstream of the valve).

ISA Delta Pressure - Current differential pressure using the pressure definitions above.

Process Temperature - Current process temperature. Gas Flow - Current gaseous flow rate. Auxiliary 4-20 Input - Re-transmits the 4-20 mA signal from

analog in No. 2.

Analog Command - This option sets up the first analog input (analog No. 1) in the StarPac II system. This analog channel is reserved as a control input. The signal is used either as a valve position command, if the StarPac II is in Manual mode, or as the controller setpoint if the StarPac II is in Auto mode. (The source of the command or setpoint is selected in the T

UNE menu after it has

been configured here.) When this option is selected you are first prompted for the interpretation of the analog signal. The signal can be interpreted as Normal (4-20 mA = 0-100%), which means that 4 mA will indicate the 0 percent signal, or as Reverse (4-20 mA = 1000%), which then interprets 20 mA as the 0 percent signal.

Next, you are prompted for the hold time (in seconds) that you want the system to hold the last command if the 4-20 mA signal should be lost (defined as having the signal drop below 3 mA). The last prompt requests a ramp rate that the system will use to fail the valve if the signal has been lost and the hold time has expired. A negative value will ramp the valve closed at the selected rate, and a positive value

StarPac II User Interface Manual 18

will open the valve at the selected rate. (Note that this value may be set different from the spring failure of the actuator.)

Analog In 2 - This option sets up the second analog input in the StarPac II system. This input can be used as an external input that is used with the internal PID controller, or as an external sensor input for the StarPac II to use in its internal operation. If you wish to use the input as a controller input, you must select the NOT CONNECTED option since the scaling for the PID input is done in

UNE menu with the Process variable selection. If you want to

the T feed an external variable into the StarPac II, select the variable from the list using the NEXT and PREVIOUS function keys on the menu. Next, you will be asked for a full scale input value in your userdefined units. (This is the process value that corresponds to the 100 percent signal.) The last step is to enter the offset or Zero input value in your user-defined units. (This is the process value that corresponds to the 0 percent signal). The available input variables are:

Not Connected - Configures the StarPac II unit to ignore the input as an internal variable, but the input may still be used as an input to the controller that is configured with the process variable selection in the T

UNE menu.

Process Temperature - Uses the value from the Auxiliary input channel as the process temperature for all internal calculations in place of the StarPac II sensor. The electronics assumes that the Auxiliary input channel gets its signal from a temperature transmitter.

Up Stream Pressure - Uses the signal from an external pressure transmitter connected to the Auxiliary input channel as the process pressure for all internal calculations in place of the StarPac II sensor.

Down Stream Pressure - Uses an external pressure input as the process pressure for all internal calculations in place of the StarPac II sensor.

Valve Delta Pressure - Uses an external pressure input as the process differential pressure for all internal calculations (in place of the StarPac II differential pressure calculated by the difference from the StarPac II internal pressure sensors). The most common example is when a separate differential pressure transmitter is used for cases when the application cannot withstand pressure drops of at least ten percent of inlet pressure.

Molecular Weight - Uses an external molecular weight input for all internal calculations in place of the static value stored in the StarPac II configuration.

Specific Gravity - Uses an external Specific Gravity input for all internal calculations in place of the static value stored in the StarPac II configuration.

Liquid Fudge Factor - This input allows you to make dynamic adjustments to the liquid flow calculation based on the value of the input.

Gas Fudge Factor - This input allows you to make dynamic adjustments to the gaseous flow calculation based on the value of the input.

StarPac II User Interface Manual

Air Action - Used to set up the StarPac II for the configured actuator

failure mode. ATO (Air-to-Open) is normally used for fail-closed valves, ATC (Air-to-Close) is normally used for fail-open valves. If ATC is selected and you will be using an analog command source, configure the analog command to reverse so that 4 mA equals the 100 percent position (open). The following table lists the possible configurations:

Low Air - This option is used to set the trip parameters for low supply air to the system, which is continuously monitoring the air supply in the actuator. Using the actuator pressures, the StarPac II can infer the supply pressure to within five to 10 psi. If the supply pressure drops below the Low Air Trip Pressure then the positioner will attempt to hold the valve for the time specified in the hold parameter and then ramp to the spring failure position at the specified Low Air Ramp Rate.

Softlimits - (Softlimits are stroke limits set and maintained by the system’s electronics or software. These limits are only in effect when the unit has power and is not in Test mode. When power has failed or cut off to the StarPac II, the valve will fail to its mechanical stops or limits.) This option allows you to set software limits on the travel of the valve. These limits are active in Auto and Manual modes, but they do not affect failure modes. Normally these limits are set to -10 and 110 percent of travel so they do not affect valve operation.

Units -The StarPac II system has individually configurable units for Process Pressure, Liquid flow, Gas flow, Process temperature, and actuator pressure. Units for each type of process variable are set in the Unit menu. (See Figure 8)

Pulse Relay Output - Configures the Pulse Out channel on the StarPac II system for the process variable and scaling. First you must select a variable from the list using the Next and Previous function keys on the menu. Next you are asked for a full scale output value in your selected user units. (This is the process value that corresponds to the maximum frequency.) The last step is to enter the offset or zero output value in your selected user units (this is the process value that corresponds to 0 Hz). Available output variables are the following:

Valve Position - Current valve position. Liquid Flow - Current liquid flow rate. ISA Up Stream Press - Current compensated upstream line

pressure (defined as two pipe diameters upstream of the valve). ISA Dn Stream Press - Current compensated downstream line

pressure (defined as six pipe diameters downstream of the valve).

ISA Delta Pressure - Current differential pressure using the pressure definitions above.

Process Temperature - Current process temperature. Gas Flow - Current gaseous flow rate. Auxiliary 4-20 Input - Re-transmits the 4-20 mA signal from

Changing or Viewing the Fluid Specification

The StarPac II system must be configured for the exact fluid that you have in your process. The factory configures the system with fluid data for your system using the information supplied with the order. Verify that the fluid data is correct for your process. The StarPac system requires the following fluid data for accurate flow calculation:

Antoine’s A coefficient register 70329 Antoine’s B coefficient register 70331 Antoine’s C coefficient register 70333 Critical Pressure in psia register 70341 Critical Temperature in ºR register 70343

Molecular Weight register 70347 Specific Gravity Reference temp in ºR register 70349 Specific Gravity at reference temp register 70351 Viscosity A register 70541 Viscosity B register 70543 The Antoine coefficients are used to calculate the vapor

pressure of the fluid at the temperature measured by the K thermocouple in the StarPac according to the following equation:

VP A

exp( )

where VP is the vapor pressure in psia, T is the temperature in °R, and A, B, and C are the Antoine coefficients.

Viscosity is calculated according to the following equation:

Where Visc is the fluid viscosity in centipoise, T is the process temperature measured by the thermocouple in °F, and A and B are the viscosity coefficients.

These registers can be checked using either the View option of the

TATUS menu or the View selection in the Tech option of the

ONFIGURE menu. They can be changed using the Edit selection in

C the Tech option of the C

ONFIGURE menu.

Setting the Jumpers

The StarPac II system has several jumpers that are used to configure the digital and discrete I/O. Two jumpers are on the personality card (the small card in the lower right-hand side) and are visible when the inner door is opened. The personality card must be removed to change the discrete jumpers located on the board below the personality card. To remove the personality card, remove the four small screws that hold the card in place and gently remove it by gripping the notch at the lower right-hand corner of the card.

RS- 485 Termination - On the personality card there are two termination jumpers for the COMM A and B for the RS-485 communications. These jumpers should only be installed on the two most remote devices on the network. Count the host computer as any other device. For example, a single StarPac II system is communicating with a host PC in the control room. The StarPac II unit and the RS-485 driver in the host computer would each require a termination jumper. Remove the termination jumpers in the devices not considered to be the most remote. Using more than two termination jumpers in a network may cause the RS-485 communications to fail.

Alarm Relay Setting - Under the personality card is a three position jumper labeled “Relay.” This jumper, if set in the A-B position, configures the relay to Normally-open operation. If set to the B-C

StarPac II User Interface Manual 26

position, the jumper configures the relay to Normally-closed operation.

Discrete Input Range Selection - Under the personality card are two sets of three position jumpers labeled “DI1” and “DI2.” DI1 refers to discrete input No. 1 and DI2 to discrete input No. 2. In the A-B position the input is set to trigger on 120V AC or DC. In the B-C position the input is set to trigger on 24V AC or DC. These jumpers must be moved in pairs for each individual relay, but each relay may be setup differently.

Troubleshooting

If you experience problems with your system, check the following list for some common solutions.

LCD blank and no system response - Check 24 VDC supply polarity and capacity (>300 mA).

LCD Hard to view - In the C for a better viewing angle.

LCD active, unit will not respond to position or control commands, and the analog outputs do not change - Check

to see if the unit is in Test mode by looking for a flashing “T” on the right side of the display. The unit will be in Test mode any time you are in the C

to move up to the top of the menu and exit from Test mode. If that does not clear the flashing “T” from the display, go to the

UNE menu and use the mode command to put the system in

T Auto or Manual mode. If the system displays a flashing “E” or “A” on the left side of the display, check the cause of the error or alarm using the ERR/ALRM option in the S Alarm is a trip condition, then you can view the cause of the trip by setting the ROW1 variable to show Mode/Status in the

TATUS menu.

S System will not respond to discrete commands - Check

jumper selection to make sure the input is set to the proper range and that the system is not in Test mode.

Pressure sensors appear to saturate prematurely - Check the rating of the sensors in the system information option of the

TATUS menu to verify the rating (the rating is also etched on the

S sensor). Check the sensor gain (set in the C the P1 & P2 option (the standard range is 39 mV < out < 78 mV).

Stroke calibration aborts or hangs - Check the air supply and make sure it is stable. A regulator may be required to stabilize the air supply in some systems.

Detailed StarPac ll Register Map

This reference will aid you in understanding the configuration of the StarPac ll register table. Registers are described and notes are provided that give the range and more detailed information.

The StarPac ll register table consists of three different types of information: integers, IEEE floating point numbers and strings. These types can have a read only (RO) access attribute or a read/write (RW) access attribute. You can only read RO registers. Writing to a RO register will generate an exception error. You can both read and write to RW registers.

The register numbering is as follows: a 30000 base indicates RO integers, a 40000 base indicates RW integers, a 70000 base indicates floating point numbers, and a 50000 base indicates strings. For example, a register number of 30003 indicates a RO integer.

Two contiguous integer registers make up a floating point register. You will get an exception response if you try to access into the middle of a floating point register.

Registers making up bit fields follow the MSB/LSB (Most Significant Byte/Least Significant Byte) format. Internally, Valtek calculates the StarPac ll variable numbers by taking the module of the register number

and 10,000 and subtracting 1. For example, register number 30001 would become variable number 0.

String Registers

The register numbers in this table are not consecutive because of the varying length of each string in this area of StarPac memory. Most of these strings are available as RW strings; however, we suggest that you only write to 50617 (TAGNAME) and 50625 (Real time and date) and leave the others as they are because that information is factory set.

Trying to access the middle of a string will result in an exception response from the device.

StarPac II User Interface Manual 50

StarPac Wiring and Grounding Guidelines

This guideline will help you in achieving maximum noise rejection and performance with a StarPac Intelligent Control System. This guide must NOT be used to supersede local electrical code or plant safety wiring practices.

Shielding Versus Grounding

All signals to the StarPac system should be in shielded cables. Shields must be tied to a ground at only one end of the cable to provide a place for environmental electrical noise to be removed from the cable. A ground wire, unlike a shield, is attached at both ends to provide a continuous path for electrical conductivity.

Grounding Screw

The grounding screw by the user interface terminal block should be used to provide the unit with an adequate and reliable earth ground reference. Either one of the mounting screws holding the terminal block may be used as a grounding screw. This ground should be tied to the same ground as the electrical conduit. Additionally, the electrical conduit connecting to the StarPac unit should be earth grounded at both ends of its run. The StarPac II grounding screw should not be used to terminate any signal shield wires.

24 VDC Power

The 24 VDC connection points will work best with shielded twisted pair wire with the shield wire connected only at the source. The input power is isolated within the StarPac II system and may be referenced to whatever level is necessary. For best performance the 24 VDC power supply should not be connected to earth ground.

RS-485 Communication

RS-485 wiring requires shielded twisted pair wire. Maximum performance will be attained when using cable with a characteristic impedance of 120 ohms. The shield should be connected only at the source, not in the StarPac unit. The StarPac II internal system ground is isolated and not earth ground referenced. The RS-485 port can float to whatever common mode voltage appears at its input terminals. These signals are referenced to the StarPac internal system ground, and because of this it is the main fault path when one of the isolation points fail. For this reason special care must be taken to ensure that the RS-485 cable is wired correctly. The RS-485 allows only a -7 to 12V common mode voltage differential between stations. This means that an RS-485 network connected to multiple devices must not have more than one grounding point. Valtek's RS-232/RS-485 converter is not a grounded connection, it is fully isolated and is not a ground point. However, PC's with internal RS-485 cards are often earth grounded and if another communication device is on the network that also has an earth ground, a fault condition will almost certainly exist due to transient and steady state differences in ground potential.

StarPac II User Interface Manual

4-20 mA Command Input, Auxiliary Input, and Feedback Output

These signals are isolated but shielded twisted pair wire should be used to reduce crosstalk from other signals. Again, the shield should be connected only at the source.

Discrete Inputs and Outputs These signals are isolated, yet because they are frequently used to

switch high voltage (120 VAC), they should be run in separate shielded wire paths away from the other StarPac signals.

AIB and RS-232 to RS-485 Converter Connection

When connecting a StarPac system to an AIB or RS-232 to RS-485 converter, no shield or ground connections exist, the 24 VDC power and RS-485 communication shield drain wires must be connected to a convenient ground near the AIB or converter--no other grounding is needed.
