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.

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

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

will receive the setpoint information.

- 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.)
