Using This manUal

USB Programming Port

This manual contains installation and programming instructions for the PAX2C and all applicable option cards. For ease of installation it is recommended that the Installation Guide received with the controller be used for the installation process.

Only the portions of this manual that apply to the application need to be read. Minimally, we recommend that General Controller Specifications, Reviewing the Front Buttons and Display, and Crimson® Programming Software portions of this manual be read in their entirety.

We highly recommend that controller programming be performed using Crimson programming software. When using Crimson, the programming portion of this manual serves as an overview of the programming options that are available through Crimson. The programming section of the manual will serve to provide expanded explanations of some of the PAX2C programming features found in Crimson.

For users who do not intend to use Crimson to program their controller, this manual includes information to provide for a user to program one, or all, of the

programming parameters using the controller’s keypad. Note that due to the extensive programming features of the PAX2C, complete programming of the controller using the controller’s keypad is not recommended.

When a FlexCard™ is installed, additional parameters may be available.

Unique FlexCard parameters are defined in 7.0 Programming the FlexCard. Parameters identified as FCx that are not defined in the FlexCard programming portion of the manual function as defined in 6.0 Programming the PAX2C.

To find information regarding a specific topic or mnemonic, it is recommended that the manual be viewed on a computer and the “find” function be used. The alternate method of finding information is to identify the programming parameter involved (Input, Output, Display, PID, Alarm, or Communication) and review the information contained in the section of the manual that pertains to that parameter.

CrimsOn PrOgramming sOfTware

Crimson® software is a Windows® based program that allows configuration of the PAX® controller from a PC. Crimson offers standard drop-down menu commands, that make it easy to program the controller. The controller’s program can then be saved in a PC file for future use.

PrOgramming Using CrimsOn:

Crimson is included on the Flash Drive that is shipped with the PAX2C. Check for

updates to Crimson at http://www.redlion.net/crimson2.

- Install Crimson. Follow the installation instructions provided by the source from which Crimson is being downloaded or installed.

- Using a USB Type A-Mini B cable, plug the Mini B end of the cable into the PAX2C USB Programming Port.

- Plug the other end of the USB cable into an available USB port on the PC.

- Apply power to the PAX2C. If a FlexCard has been removed, or has had the address changed, error message(s) will need to be resolved before continuing. See Troubleshooting, on page 61, for error message resolution.

- Start Crimson.

- Click the Crimson “Link” tab.

- Click “Extract…”

o Crimson will extract the current program settings from the PAX2C.

o If the controller has not been programmed, the extracted file will contain

factory settings. Note that the PAX2C factory settings vary based on the option cards installed.

o Crimson will display a PAX2C with various areas described by the

programming parameters that pertain to the area.

- Double click on the “Analog/User Inputs/F Keys/PID” area.

- Make configuration selections. For information regarding a configuration selection, hover the curser over the selection area.

- Make configuration selections for each tab that appears across the top. When completed click “Close”.

INSTALLATION

The PAX2C meets NEMA 4X/IP65 requirements when properly installed. The controller is intended to be mounted into an enclosed panel. Prepare the panel cutout to the dimensions shown. Remove the panel latch from the controller. Slide the panel gasket over the rear of the controller to the back of the bezel. The controller should be installed fully assembled. Insert the controller into the panel cutout.

While holding the controller in place, push the panel latch over the rear of the controller so that the tabs of the panel latch engage in the slots on the case. The

panel latch should be engaged in the farthest

forward slot possible. To achieve a proper

seal, tighten the latch screws evenly until

the controller is snug in the panel

(Torque to approximately 7 in-lbs [79N-

cm]). Do not over-tighten the screws.

2.0 seTTing The JUmPers

The PAX2C controller has four jumpers that must be checked and/or changed prior to applying power. The following Jumper Selection Figures show an enlargement of the jumper area.

To access the jumpers, remove the controller base from the case by firmly squeezing and pulling back on the side rear finger tabs. This should lower the latch below the case slot (which is located just in front of the finger tabs). It is recommended to release the latch on one side, then start the other side latch.

Warning: Exposed line voltage exists on the circuit boards. Remove

all power to the controller and load circuits before accessing inside of the controller.

INSTALLATION ENVIRONMENT

The controller should be installed in a location that does not exceed the operating temperature and provides good air circulation. Placing the controller near devices that generate excessive heat should be avoided.

The bezel should only be cleaned with a soft cloth and neutral soap product. Do NOT use solvents. Continuous exposure to direct sunlight may accelerate the aging process of the bezel.

Do not use tools of any kind (screwdrivers, pens, pencils, etc.) to operate the keypad of the controller.

Current Input

For current input, only one jumper must be configured to select the current range. This jumper is shared with the voltage input range. To avoid overloads, select the jumper position that is high enough to accommodate the maximum signal input level to be applied.

Note: The position of the T/V jumper does not matter when the controller is in the current input mode.

Temperature Input

For temperature measurement the T/V jumper must be in the T (temperature) position. For RTD sensors the RTD jumper must also be set.

Resistance Input

Three jumpers are used to configure the resistance input. The T/V jumper must be in the V (voltage) position, and the excitation jumper must be in the

1.05 mA REF position. The voltage/resistance jumper position is determined by the input range.

Excitation Output Jumper

This jumper is used to select the excitation range for the application. If excitation is not being used, it is not necessary to check or move this jumper.

4.0 wiring The COnTrOller

WIRING OVERVIEW

Electrical connections are made via terminals located on the back or top of the controller. All conductors should conform to the controller’s voltage and current ratings. All cabling should conform to appropriate standards of good installation, local codes and regulations. It is recommended that the power supplied to the controller (DC or AC) be protected by a fuse or circuit breaker.

When wiring the controller, compare the numbers embossed on the back of the controller case to those shown in wiring drawings for proper wire position. Strip the wire, according to the terminal block specifications (stranded wires should be tinned with solder). Insert the lead into the correct terminal and then tighten the terminal until the wire is secure (Pull wire to verify tightness).

EMC INSTALLATION GUIDELINES

Although Red Lion Controls Products are designed with a high degree of immunity to Electromagnetic Interference (EMI), proper installation and wiring methods must be followed to ensure compatibility in each application. The type of the electrical noise, source or coupling method into a unit may be different for various installations. Cable length, routing, and shield termination are very important and can mean the difference between a successful or troublesome installation. Listed are some EMI guidelines for a successful installation in an industrial environment.

1. A unit should be mounted in a metal enclosure, which is properly connected

to protective earth.

2. Use shielded cables for all Signal and Control inputs. The shield connection

should be made as short as possible. The connection point for the shield

depends somewhat upon the application. Listed below are the recommended

methods of connecting the shield, in order of their effectiveness.

a. Connect the shield to earth ground (protective earth) at one end where the

b. Connect the shield to earth ground at both ends of the cable, usually when

3. Never run Signal or Control cables in the same conduit or raceway with AC

power lines, conductors, feeding motors, solenoids, SCR controls, and

heaters, etc. The cables should be run through metal conduit that is properly

grounded. This is especially useful in applications where cable runs are long

and portable two-way radios are used in close proximity or if the installation

unit is mounted.

the noise source frequency is over 1 MHz.

is near a commercial radio transmitter. Also, Signal or Control cables within an enclosure should be routed as far away as possible from contactors, control relays, transformers, and other noisy components.

4. Long cable runs are more susceptible to EMI pickup than short cable runs.

5. In extremely high EMI environments, the use of external EMI suppression devices such as Ferrite Suppression Cores for signal and control cables is effective. The following EMI suppression devices (or equivalent) are recommended:

Fair-Rite part number 0443167251 (RLC part number FCOR0000) Line Filters for input power cables:

6. To protect relay contacts that control inductive loads and to minimize radiated and conducted noise (EMI), some type of contact protection network is normally installed across the load, the contacts or both. The most effective location is across the load. a. Using a snubber, which is a resistor-capacitor (RC) network or metal oxide

varistor (MOV) across an AC inductive load is very effective at reducing EMI and increasing relay contact life.

b. If a DC inductive load (such as a DC relay coil) is controlled by a transistor

switch, care must be taken not to exceed the breakdown voltage of the transistor when the load is switched. One of the most effective ways is to place a diode across the inductive load. Most RLC products with solid state outputs have internal zener diode protection. However external diode protection at the load is always a good design practice to limit EMI. Although the use of a snubber or varistor could be used. RLC part numbers: Snubber: SNUB0000 Varistor: ILS11500 or ILS23000

7. Care should be taken when connecting input and output devices to the instrument. When a separate input and output common is provided, they should not be mixed. Therefore a sensor common should NOT be connected to an output common. This would cause EMI on the sensitive input common, which could affect the instrument’s operation.

Main Display Loop

In the Main display loop, the D key is pressed to advance through the selected Line 2 values. The Line 2 units mnemonics are used to indicate which Line 2 value is currently shown. When in the Main display loop, the Function keys perform the user function as programmed in the User Input parameter section.

Parameter and Hidden Parameter Display Loops

To utilize the Hidden Parameter display loop, a security code (1-250) must be programmed. (See Programming Security Code in the Display Parameters programming section for details.)

The Parameter display loop is accessed by pressing the P key (key must be pressed twice if displaying a dEnt value). The selected Parameter display loop values can be viewed and/or changed per the Line 2 Value Access setting programmed for each available value. The Hidden Parameter display loop follows the Parameter display loop, and can only be accessed when the correct security code is entered at the Code prompt. Combining the two parameter loops provides an area for parameters that require general access and/or protected or secure access depending on the application needs.

While in the Parameter and Hidden Parameter loops, pressing the D key will return the controller to the Main display loop. To directly access the Code prompt, press and hold the P key. This can be done from the Main display loop or at any point during the Parameter display loop. Also, to directly access Full Programming mode while in the Hidden Parameter loop, press and hold the P key to bypass any remaining Hidden Parameter loop values.

6.0 PrOgramming The PaX2C

It is highly recommended that controller programming be performed using Crimson programming software. Program settings should be saved or recorded as programming is performed.

BASIC/ADVANCED CONFIGURATION MODE

The PAX2C provides two different user selectable configuration modes:

Basic Configuration Mode (bSIC)

Basic is the default mode. When the PAX2C is configured in this mode, a maximum of four alarms are supported and no mapped backlight color changes are available. Default backlight colors are user selectable.

Advanced Configuration Mode (AdUC)

In the Advanced mode, a maximum of sixteen alarms are supported and all backlight color configuration menu parameters are enabled. Select this mode when you require more than four alarms or where process dependent display color changes are desired.

FULL PROGRAMMING ENTRY

Full Programming is entered by pressing and holding the P key. Full Programming will be accessible unless the controller is programmed to use the Hidden Parameter loop or PLOC is active with CodE = 0. In this case, programming access will be limited by a security code and/or a hardware program lock. (Refer to the previous section for details on Line 2 display loops and limited programming access.) Full Programming permits all parameters to be viewed and modified. In this mode, the front panel keys change to Programming Mode Operations and certain user input functions are disabled.

MAIN PROGRAMMING LOOP

The Main Programming Loop provides access to seven main programming

modules. These modules group together functionally related parameters. The ! and @ keys are used to select the desired programming module. The displayed module is entered by pressing the P key.

PARAMETER PROGRAMMING SELECTION LOOP

After entering (P key) a main programming module selection, the user gains

access to the programming selection loop. This loop breaks down the specific module into more specific and detailed parameter groups. For example, the Input Parameter module provides for selection of Analog and User input parameters. The ! and @ keys are used to select the desired parameter programming selection. The parameter programming selection is entered by pressing the P key.

PARAMETER PROGRAMMING LOOP

After entering (P key) a parameter in the parameter programming selection

loop, the Parameter Programming Loop is entered. This loop is a sequence of parameters that can be changed/programmed. The P key is pressed to enter the program selection and advance to the next parameter. After advancing through all the parameters in the Parameter Programming Loop, the display returns to the Parameter Programming Selection Loop.

If a parameter selection has been changed, the P key must be pressed in order

to save the change. Pressing the D key before pressing the P key will cause the unit to abort a selected change.

SELECTION/VALUE ENTRY

For each parameter, the top line display shows the parameter while the

bottom line shows the selections/value for that parameter. The ! and @ keys are used to move through the selections/values for the parameter. Pressing the P key, stores and activates the displayed selection/value. This also advances the controller to the next parameter.

Numerical Value Entry

The ! and @ keys will increment or decrement the parameter value.

When the ! or @ key is pressed and held, the value automatically scrolls. The longer the key is held the faster the value scrolls.

For large value changes, press and hold the ! or @ key. While holding

that key, momentarily press the opposite arrow key (@ or !) to shift decades (10’s 100’s, etc), or momentarily press the D key and the value scrolls by 1000’s as the arrow key is held. Releasing the arrow key removes the decade or 1000’s scroll feature. The arrow keys can then be used to make small value changes as described above.

PROGRAMMING MODE EXIT

To exit the Programming Mode, press and hold the D key (from anywhere

in the Programming Mode) or press the P key with Pro NO displayed. This will commit stored parameter changes to memory and return the controller to the Display Mode. If a parameter was just changed, the P key must be pressed to store the change before pressing the D key. (If power loss occurs before returning to the Display Mode, verify recent parameter changes.)

PROGRAMMING TIPS

It is highly recommended that controller programming be performed using

Crimson programming software. If lost or confused while programming using the keypad method, press and hold the D key to exit programming mode and start over. Program settings should be saved or recorded as programming is performed. When programming is downloaded or completed, lock out programming with a user input or lock-out code.

Factory Settings may be completely restored in the Factory Service Operations module. This is useful when encountering programming problems.

Example: It is necessary to square root linearize the output of a differential

pressure transmitter to indicate and control flow. The defining equation is F = 278 ÖΔP , where ΔP = 0 - 500 PSI, transmitted linearly by a 4 - 20 mA

transducer. At full flow rate ( ΔP = 500 PSI), the flow is 6216 ft3/h. The

following scaling information is used with the controller:

As a result of the scaling and square root linearization, the following

represents the readings at various inputs:

This parameter allows the controller to be used in applications in

which the measured signal is the square of the process value (PU). This is useful in applications such as the measurement of flow with a differential pressure transducer.

The two user inputs are individually programmable to perform specific control functions. While in the Display Mode or Program Mode, the function is executed the instant the user input transitions to the active state. The front panel function keys, ! and @, are also individually programmable to perform specific control functions. While in the Display Mode, the primary function is executed the instant the key is pressed. Holding the function key for three seconds executes a secondary function. It is possible to program a secondary function without a primary function.

In most cases, if more than one user input and/or function key is programmed for the same function, the maintained (level trigger) actions will be performed while at least one of those user inputs or function keys are activated. The momentary (edge trigger) actions will be performed every time any of those user inputs or function keys transition to the active state.

Note: In the following explanations, not all selections are available for both user inputs and front panel function keys. Displays are shown with each selection. Those selections showing both displays are available for both. If a display is not shown, it is not available for that selection. USrx will represent both user inputs.

When a non-linear Analog Output signal is desired, up to 16 scaling points may be used to provide a piece-wise linear approximation. (The greater the number of scaling points used, the greater the conformity accuracy.) The Analog Output signal will be linear between sequential scaling points.

This section provides information regarding parameters that can be programmed to display on Line 2 Display (Bottom Line). Various input, display, PID, alarm, and function parameters can be programmed to be viewed in the various Line 2 display loops.

Parameter Access Selections

Parameters to be viewed/entered on Line 2 are configurable by using the Parameter Access Selection. Line 2 parameter values can be made accessible in the Main (D Key), Parameter (P key), and Hidden (P key following code entry) display loops. Parameter Access Selections indicate the display loop by the first character of the selection. d = Display Loop, P = Parameter Loop, and H = Hidden Loop. The remaining three characters indicate if the selection allows for the parameter to only be viewed (rEd) or if the parameter can be viewed and entered (Ent). An Ent selection for HI or LO parameters allows the parameter to be reset in the corresponding display loop. An Ent selection for any of the FNCt parameters allows the parameter to be changed within the corresponding display loop. For a description of the FNCt parameter function, refer to the corresponding parameter description in the User Input/Function Key Parameters (User) section. The key sequence required to make a change is dependent on the display loop in which the change is being performed. Refer to the Parameter Access descriptions that follow for the specific key sequence required. Pressing the P key takes you into the Parameter Loop and is also used to step through the loop. Parameters may be configured for multiple display loop access selections. Not all settings are available for each parameter. The Parameter Access table indicates which settings are available for each parameter.

SELECTION DESCRIPTION

Parameters selected as drEd or dEnt will be consecutively displayed on Line 2

by pressing the D key. While viewing a parameter selected as dEnt, the parameter setting can be changed by pressing the P key, using the ! and @ keys to make a change, and then pressing the P key to make the change active. The Line 2 units mnemonic indicates the parameter currently being displayed on Line 2. While viewing parameters in the Display Loop, which are not presently being changed, pressing a function key will perform the user function as programmed in the User Input program section.

Parameter and Hidden Loop Parameter Access

Parameters selected as PrEd, PEnt, HrEd, or HEnt will be consecutively

displayed on Line 2 when advancing through the Parameter or Hidden display loops. The P key is used to advance through these loops. While viewing a parameter selected as PEnt or HEnt, the parameter setting can be changed by using the ! and @ keys to make a change and then pressing the P key to make the change active and advance to the next available parameter. The Line 2 units mnemonic indicates the parameter currently being displayed on Line 2. Function keys are disabled while in the Parameter and Hidden display loops.

OPeraTiOn Overview

CONTROLLER POWER-UP

Upon applying power, the controller delays control action and temperature indication for several seconds to perform several self-diagnostic tests and display basic controller information. Initially, the controller illuminates both displays and all annunciators to allow verifification that all display elements are functioning. The controller then displays the unit model type on the top display as well as the current firmware revision number on the bottom display. The controller then checks for correct internal operation and displays an error message (Exx) if an internal fault is detected (see Troubleshooting for further information). Upon completion of this sequence, the controller begins control action by displaying the temperature/process value and updating the output(s) based on the PID control calculation.

START-UP

The controller’s PID settings must be “tuned” to the process for optimum control. Minimal tuning consists of adjusting the Proportional Band, Integral Time, and Derivative Time parameters to achieve the optimum response to a process disturbance. The controller should only need to be tuned once, but must be re-tuned if the process has been significantly changed. Several options exist for tuning these parameters:

A) Use the controller’s built-in Auto-Tune feature (see Auto-Tune).

COnTrOl mOde eXPlanaTiOns

ON/OFF CONTROL

The controller operates in On/Off Control when the Proportional Band is set to 0.0. In On/Off control, the process will constantly oscillate around the setpoint value. The On/Off Control Hysteresis (balanced around the setpoint) can be used to eliminate output chatter. The Output Assignment can be set for heating (reverse - output on when below the setpoint) or for cooling (direct output on when above the setpoint) applications.

B) Use a manual tuning technique (see Manual Tuning). C) Use a third party tuning software package (generally expensive and not

always precise).

D) Use values based on control loop experience, calculated values or values

from a similar process.

If the controller is a direct replacement, the PID settings from the controller being replaced may be used as good initial values. If not a direct replacement, be sure to consider any differences in the controllers and the PID settings when replacing. The PAX2C proportional band is entered in process units. Other RLC products may use a percentage of the input range. The PID settings may be fine tuned by using the techniques outlined in the PID Control section. After tuning the controller to the process, it is important to power the load and the controller at the same time for best start-up response.

CONTROLLER POWER-DOWN

At power down, all parameters and programming is saved to provide a quick and predictable process response on the next power-up. Powering down the controller at the same time the process is powered down will prevent integral wind-up.

PID CONTROL

POWER (%

In PID Control, the controller processes the input and then calculates a control output power value by use of a specialized control algorithm. The system is controlled by the output power value to keep the process at the setpoint. The Control Action for PID Control can be set to reverse for heating (output on when below the setpoint) or direct for cooling (output on when above the setpoint) applications. For heat and cool systems, the heat and cool outputs are used. The PID parameters can be established by using Auto-Tune, or they can be manually tuned to the process.

ANALOG OUTPUT PID CONTROL

In Linear PID Control applications, the Analog Output Assignment ASGN is set to % Output Power, OP. The Analog Low Scale Value (ANLO), is set to 0.0 and the Analog High Scale Value (ANHI), is set to 100.0 (heating) or -100.0 (cooling). The Analog Output will then be proportional to the PID calculated % output power for Heat or Cooling per the PID Control Type. For example, with 0 VDC to 10 VDC (scaled 0 to 100%) and 75% power, the analog output will be 7.5 VDC.

In Non-Linear Control applications, such as process or valve control, the Analog Output Custom Scaling option will need to be configured to linearize the analog output signal with the PID Output Power. This configuration will need to be completed prior to tuning or controlling the process. See Section

6.2.1 Analog Output Parameters for more information.

In Automatic Control Mode, the percentage of output power is automatically determined by PID or On/Off calculations.

TIME PROPORTIONAL PID CONTROL

In Time Proportional applications, the output power is converted into output On time using the Cycle Time. For example, with a four second cycle time and 75% power, the output will be on for three seconds (4 × 0.75) and off for one second.

The cycle time should be no greater than 1/10 of the natural period of oscillation for the process. The natural period is the time it takes for one complete oscillation when the process is in a continuously oscillating state.

Pid COnTrOl Overview

PROPORTIONAL BAND

Proportional band is defined as the “band” of process units that the process

changes to cause the percent output power to change from 0% to 100%. The band may or may not be centered about the setpoint value depending upon the steady state requirements of the process. The band is shifted by manual offset or integral action (automatic reset) to maintain zero error. Proportional band is expressed as process display units.

MANUAL CONTROL MODE

In Manual Control Mode, the controller operates as an open loop system

(does not use the setpoint or process feedback). The user manually adjusts the percentage of output power (OP). Manual operation provides 0 to 100% power to the HEAt output and -100 to 0% power to the COOL output. The Low and High Output Power limits do not apply when the controller is in Manual.

CONTROL MODE TRANSFER

When transferring the control mode between Automatic and Manual, the controlling outputs remain constant, exercising true “bumpless” transfer. When transferring from Manual to Automatic, the power initially remains steady, but Integral Action corrects (if necessary) the closed loop power demand at a rate proportional to the Integral Time.

INTEGRAL TIME

Integral time is defined as the time, in seconds, in which the output due to integral action alone equals the output due to proportional action with a constant process error. As long as a constant error exists, integral action repeats the proportional action every integral time. Integral action shifts the center point position of the proportional band to eliminate error in the steady state. The units of integral time are seconds per repeat.

Integral action (also known as “automatic reset”) changes the output power to bring the process to setpoint. Integral times that are too fast (small times) do not allow the process to respond to the new output value. This causes over compensation and leads to an unstable process with excessive overshoot. Integral times that are too slow (large times) cause a slow response to steady state errors. Integral action may be disabled by setting the time to zero. If time is set to zero, the previous integral output power value is maintained.

If integral action is disabled, manual reset is available by modifying the output power offset (OPOF initially set to zero) to eliminate steady state errors.

HEATING COOLING

SETPOINT

TEMPERATURE

The proportional band should be set to obtain the best response to a disturbance while minimizing overshoot. Low proportional band settings (high gain) result in quick controller response at expense of stability and increased overshoot. Settings that are excessively low produce continuous oscillations at setpoint. High proportional band settings (low gain) result in a sluggish response with long periods of process “droop”. A proportional band of 0.0 forces the controller into ON/OFF control mode with its characteristic cycling at setpoint (See ON/OFF Control for more information).

Derivative time is defined as the time, in seconds, in which the output due to proportional action alone equals the output due to derivative action with a ramping process error. As long as a ramping error exists, the derivative action is “repeated” by proportional action every derivative time. The units of derivative time are seconds per repeat.

Derivative action is used to shorten the process response time and helps to stabilize the process by providing an output based on the rate of change of the process. In effect, derivative action anticipates where the process is headed and changes the output before it actually “arrives”. Increasing the derivative time helps to stabilize the response, but too much derivative time coupled with noisy signal processes, may cause the output to fluctuate, yielding poor control. Little or no derivative action usually results in decreased stability with higher overshoots. No derivative action usually requires a wider proportional band and slower integral time to maintain the same degree of stability as with derivative action. Derivative action is disabled by setting the time to zero.

It is possible to toggle between these values using the PID parameter selection which is available in the PID Parameter Programming Loop. This functionality (PSEL) is also available via the user inputs, function keys or Line 2 user function.

The Active (ACt) PID parameters reflect the PID values that are selected via

the PSEL parameter. If a change is made to an active PID value, such as a user change or after an Auto-tune, the values will automatically be copied into the Primary or Alternate group depending on which group is currently selected by the PSEL parameter.

remOTe seTPOinT COnTrOl Overview

A typical remote setpoint application will require a PX2FCA0 process input FlexCard to be installed. A Process Input FlexCard is used in remote setpoint applications by selecting the FlexCard process value as the Remote Setpoint Assignment in PID SP Parameter Programming Loop. A PX2FCA0 can also be used to monitor a secondary process signal. Configuration of the PX2FCA0 as a Remote Setpoint signal allows ratio control, master setpoint/multiple slave operation, and the ability to cascade the PAX2C with another controller. Configuration of the PX2CFCA0 Process Input as a secondary process signal allows operation as a two-process cascade controller within a single unit. In either control mode, parameters are provided to scale, configure, communicate and monitor the activity of each analog input. A square root linearizer function can be used to linearize signals derived from flow transmitters.

REMOTE AND LOCAL SETPOINT OPERATION

The controller Remote Setpoint Transfer mode can be switched between Local Setpoint operation and Remote Setpoint operation. To enable PID control with Remote Setpoint operation, an analog input FlexCard is required. The Remote Setpoint hardware source is configured in the PID setpoint (SP) programming menu. The Line 2 function parameter, RSPt (Remote Setpoint transfer), which is available in the PID setpoint (SP) programming menu and can also be made available in the Display, Parameter, or Hidden loops, allows the operator to select the desired setpoint operating mode (Local/Remote). A user input or function key may also be used to perform the Remote setpoint transfer function, independent of the Remote Setpoint Transfer (rSPt) function parameter. The front panel annunciator REM is illuminated when any PID loop is in Remote Setpoint operation and is off when all PID loops are in Local setpoint operation.

CAPABILITIES WITH ADDITIONAL ANALOG INPUT OPTION (FLEXCARD)

REMOTE SETPOINT

Any installed FlexCard process value may be configured as a Remote Setpoint to the main or process input FlexCard’s PID loop. This mode of operation enables Cascade control, Ratio control and Temperature Setpoint Slave control, among others. The Remote Setpoint value used internally by the controller is:

Remote Setpoint = (Scaled FlexCard Process Value * Rtio) + bIAS

where Rtio = 0.000 to 9.999

bIAS = -999 to 9999

The Rtio and bIAS parameters offer scaling of the Remote Setpoint to adjust

control ratios or biases among related processes. In Remote Setpoint operation, the front panel annunciator REM is illuminated. When in Local Setpoint operation, this annunciator is off.

The Remote Setpoint is restricted to the setpoint limit values SPLO and SPHI.

These parameters may be used to limit the range of the Remote Setpoint to a safe or more stable control range. For Remote Setpoint signal sources that change wildly or are too sensitive to process disturbances, the Setpoint Ramp Rate Parameter (SPrr) can be used to ramp (rate limit) the Remote Setpoint reading. This can reduce the fluctuations of the secondary control loop.

TEMPERATURE RATIO CONTROL

Example: For processing purposes, it is necessary to control the temperature of

a vat of adhesive at 1.5x the temperature of a vat of the adhesive’s blending agent. The temperature of the reacting agent is manually controlled, and the setpoint of the adhesive must track that of the reacting agent. To regulate the adhesive temperature, a PAX2C with a PX2FCA0 Process Input FlexCard can be configured to provide a Remote Setpoint with a Ratio value of 1.500. A temperature transmitter from the blending agent vat is used to generate the Remote Setpoint signal.

TEMPERATURE REMOTE SETPOINT SLAVE CONTROL

Example: Multiple PAX2Cs with Process Input FlexCards are used to regulate

the temperature zones of a continuous drying oven. To reduce thermal shock to the product, the setpoint levels of incoming zone controllers are low, while the other controllers have setpoints that are increasingly ramped up to the ideal drying temperature. All but one of the PAX2Cs are used as slave controllers with unique bias values to implement the ramp (setpoint values) of the drying oven. One PAX2C is the master controller. The master controller re-transmits the setpoint value via the PAXCDL linear DC output (4-20 mA) to the slave zone controllers. The slave zone controllers receive the 4-20 mA signal as a Remote Setpoint.

CASCADE CONTROL

Cascade control involves the separation of a process into two control loops: the primary loop and the secondary loop. The secondary control loop is normally designed to regulate a faster responding process, which exists within the main process. The setpoint for the secondary control loop, by means of a remote setpoint, is provided by the primary control loop output. To maintain primary loop regulation, the primary loop output provides a remote setpoint for the secondary control loop. Disturbances occurring to the secondary process are quickly compensated for by the secondary loop controller, before the effect appears in the primary process. This early loop compensation, or “feed forward” action, of Cascade control can improve control quality compared with standard single loop control. Since the primary and secondary monitor different process inputs, they normally have different tuning (PID) values.

With the addition of a FlexCard which provides a second analog input and an additional PID controller, the PAX2C is capable of performing Cascade control. The flexibility of the PAX2C/FlexCard platform provides for the ability to assign the primary/secondary loop functions to either the main PAX2C Input/ PID or to the FlexCard Input/PID, depending on the application and available FlexCard Input type.

In Cascade control, the Primary loop provides the setpoint for the Secondary loop. This is accomplished by assigning the Remote Setpoint (RSP) for the secondary loop controller to the primary loop controller output power (OP). The Primary loop output power (0-100.0%) is scaled by the “Rtio” and “bIAS ” Remote Setpoint scaling parameters of the secondary PID controller to yield the Secondary (directed) setpoint. The Remote Setpoint is used by the secondary loop to calculate the secondary loop output (OP). Normally, the Remote Setpoint is scaled to equal the process range of the secondary. When scaled this way, the Primary controller can direct the setpoint of the Secondary controller over its entire operating range.

The setpoints can be viewed during operation by configuring the SP display LOC for the secondary loop setpoint to be displayed. For proper Auto-tuning of the Primary loop, it is necessary that the secondary loop input scaling, “dISP 1” and “dISP 2” to be respectively programmed as the actual process low and process high values of the Secondary process.

Example: The temperature of a large vat of dye is to be controlled by adjusting the steam pressure to the vat. The steam pressure range can vary from 0 to 200 psi and is sensed by a sensor with a 4 to 20mA output. The steam pressure is adjusted by opening/closing a pressure control valve that requires a 0 to 10 VDC analog input. The vat temperature is to be maintained at 285°C and is sensed using a Type T thermocouple.

A PAX2C, PAXCDL10 and a PX2FCA0 FlexCard are used in a Cascade arrangement to regulate the temperature of a large vat of dye. The PX2FCA0 is used as the secondary process controller, to monitor and control steam pressure. The input to the PX2FCA0 is wired to a pressure sensor that senses the steam pressure. The PAXCDL10 is used to provide a 0 – 10 VDC signal, which is programmed to correspond to the %OP of the PX2FCA0. The PAXCDL10 output is wired to a pressure control valve, which directly adjusts the steam pressure. A 0 volt output fully closes the valve, and a 10 volt output fully opens the valve. The PX2FCA0 is programmed for Remote Setpoint, with the setpoint configured to be provided by the output power (OP) of the PAX2C. The PAX2C is used as the primary controller, to monitor and control the vat temperature. The PAX2C input is connected to a temperature sensor that senses the temperature of the vat. The setpoint of the PAX2C is 285°C.

In some cases the Remote Setpoint signal may change too rapidly or have excessive process noise. This may lead to instability or even oscillation of the secondary controller. The Setpoint Ramp Parameter (SPrP and SPrr) is effective in limiting the amount of change to the secondary process due to the Remote Setpoint value change. The Setpoint Ramp Rate parameter should be set to a minimum value that is consistent with the response time of the primary process. Additionally, Setpoint Limit Low and Setpoint Limit High parameters (SPLO, SPHI) may be used to constrain the Remote Setpoint value to safe limits or narrow the operating range for stability purposes.

Auto-Tune is a user-initiated function where the controller automatically determines the Proportional Band, Integral Time, Derivative Time, Digital Filter, Control Ouput Dampening Time, and Relative Gain (Heat/Cool) values based on the process characteristics. The Auto-Tune operation cycles the controlling output(s) at a control point three-quarters of the distance between the present process value and the setpoint. The nature of these oscillations determines the settings for the controller’s parameters.

Prior to initiating Auto-Tune, it is important that the controller and system wiring and operation be verified. (This can be accomplished in On/Off Control or Manual Control Mode.) If there is a wiring, system or controller problem, Auto-Tune may give incorrect tuning or may never finish. Auto-Tune may be initiated at a start-up process value, when at process setpoint or at any other process point. However, insure normal process conditions (example: minimize unusual external load disturbances) as they will have an effect on the PID calculations.

TIME

AUTO-TUNE PROGRESS

The controller will cycle the controlling output(s) to generate four phases. The bottom display will flash the phase number. Parameter viewing is permitted during Auto-Tune. The time to complete the Auto-Tune phases is process dependent. The controller should automatically stop Auto-Tune and store the calculated values when the four phases are complete. If the controller remains in Auto-Tune unusually long, there may be a system problem. Auto-Tune may be stopped by entering NO in the Initiate Auto-Tune Parameter (tunE).

AUTO-TUNE OF HEAT/COOL SYSTEMS

During Auto-Tune of heat/cool systems, the controller switches the cooling output on and off in addition to the heat output. The output deadband parameter determines the amount of overlap or deadband between the two outputs during Auto-Tune. See ON/OFF Control, on page 36, for the operation of this parameter. The output deadband parameter remains unchanged after Auto-Tune is complete. Therefore, when proportional control is started after the completion of Auto-Tune, this parameter may need to be adjusted.

It is important that external load disturbances be minimized, and if present, other zone controllers idled as these may have an effect on the PID constant determination. The controller also sets the Output Heat and Output Cool Gain parameters (HtGn and CLGN) for heat/cool systems.

INITIATE AUTO-TUNE

Below are the parameters that affect Auto-Tune calculations. If changes are needed, then they must be made before starting Auto-Tune. Please note that it is necessary to configure the input and control alarm/outputs prior to initiating auto-tune.

AUTO-TUNE OF CASCADE SYSTEMS (REMOTE SETPOINT)

Cascade systems involve the use of two controllers, the Primary and the Secondary. The secondary controller must have remote setpoint capability. In such a system, the Secondary controller should be tuned first, followed by tuning of the primary controller. Prior to tuning the Secondary controller, it is essential that the Remote Setpoint is scaled to match the secondary process range. This is important for proper Auto-Tuning of the primary controller.

Subsequent changes made to scaling values may require re-tuning. The following procedure may be used to initially tune a Cascade system:

1. Place the Secondary controller into Local Setpoint mode (RSPt = LOC) and

Manual (trNF = Man) mode of operation.

2. Adjust output power level of the secondary until primary variable is close to

primary setpoint. (within 10% of range)

3. Key-in the secondary loop setpoint value equal to secondary process value.

4. Auto-Tune the secondary controller while in Local Setpoint mode (RSPt =

LOC).

5. Place the secondary controller into Remote Setpoint mode (RSPt = REM) and

Automatic (trnF = Auto) mode of operation.

6. Auto-tune the primary controller while the primary is in Automatic mode of

operation.

7. Initial tuning of system is complete.

After the process has stabilized, the primary and secondary may be re-tuned in Automatic mode of operation. Normally, the primary requires re-tuning whenever the secondary PID constants are changed. Note: For Remote Setpoint controllers, the Auto-tune control point is dependent

on the mode. In Remote Setpoint mode, it is derived from the Remote

Setpoint. In Local Setpoint mode, it is derived from the Local Setpoint.

PID ADJUSTMENTS

In some applications, it may be necessary to fine tune the Auto-Tune calculated PID parameters. To do this, a chart recorder or data logging device is needed to provide a visual means of analyzing the process. Compare the actual process response to the PID response figures with a step change to the process. Make changes to the PID parameters in no more than 20% increments from the

PROCESS RESPONSE EXTREMES

OVERSHOOT AND OSCILLATIONS SLOW RESPONSE

starting value and allow the process sufficient time to stabilize before evaluating the effects of the new parameter settings.

In some rare cases, the Auto-Tune function may not yield acceptable control results or induced oscillations may cause system problems. In these applications, Manual Tuning is an alternative.

TIME

TO DAMPEN RESPONSE:

- INCREASE PROPORTIONAL BAND.

- INCREASE INTEGRAL TIME.

- USE SETPOINT RAMPING.

- USE OUTPUT POWER LIMITS.

- RE-INVOKE AUTO-TUNE WITH A HIGHER AUTO-TUNE CODE.

- INCREASE DERIVATIVE TIME.

MANUAL TUNING

A chart recorder or data logging device is necessary to measure the time between process cycles. This procedure is an alternative to the controller’s Auto-Tune function. It will not provide acceptable results if system problems exist.

1. Set the Proportional Band (ProP) to approximately 10.0% of the input range

for temperature control (Temperature) and 100.0% for process control

(Voltage/Current).

2. Set both the Integral Time (Intt) and Derivative Time (dErt) to 0 seconds.

3. Set the active PID Power Filter (FLtr) to 0 seconds.

4. Set the Output Cycle Time (CYCt) to no higher than one-tenth of the process

time constant (when applicable).

5. Place the controller into Manual Control Mode (MAN) and adjust the % Power

to drive the process value to the Setpoint value. Allow the process to stabilize

after setting the % Power.

TIME

TO QUICKEN RESPONSE:

- DECREASE PROPORTIONAL BAND.

- DECREASE INTEGRAL TIME.

- INCREASE OR DISABLE SETPOINT RAMPING.

- EXTEND OUTPUT POWER LIMITS.

- RE-INVOKE AUTO-TUNE WITH A LOWER AUTO-TUNE CODE.

- DECREASE DERIVATIVE TIME.

6. Place the controller in Automatic (Auto) Control Mode. If the process will not stabilize and starts to oscillate, set the Proportional Band two times higher and go back to Step 5.

7. If the process is stable, decrease Proportional Band setting by two times and change the Setpoint value a small amount to excite the process. Continue with this step until the process oscillates in a continuous nature.

8. Fix the Proportional Band to three times the setting that caused the oscillation in Step 7.

9. Set the Integral Time to two times the period of the oscillation.

10. Set the Derivative Time to 1/8 (0.125) of the Integral Time.

11. Set the Output Filter to 1/40 (0.025) the period of the oscillation.

serial COmmUniCaTiOns Overview

The PAX2 supports serial communications using the optional serial communication cards or via the USB programming port located on the side of the controller. When USB is being used (connected), the serial communication card is disabled. When using the standard RS232 and RS485 PAX option cards, the PAX2 supports both RLC protocol and Modbus communications. The PAX Modbus option card should not be used with the PAX2, as the PAX2 internal Modbus protocol supports complete controller configuration, and is much more responsive.

USB

The USB programming port is primarily intended to be used to configure the PAX2 with the Crimson programming software. It can also be used as a virtual serial communications port following installation of the PAX2 USB drivers that are supplied with the Crimson software. When the USB port is being used, i.e. the USB cable is connected between PAX2 and PC, all serial communications with the serial option card (if used) is disabled.

USB Cable type required: USB A to Mini-B (not supplied)

PAX2 CONFIGURATION USING CRIMSON AND USB

1. Install Crimson software.

2. Supply power to PAX2.

3. Ensure USB Setup in USB Port Parameters is set to CNFG (factory default

setting).

4. Attach USB cable (USB A to Mini-B) between PC and PAX2.

5. Create a new file (File, New) or open an existing PAX2 database within

Crimson.

6. Configure Crimson Link options (Link, Options) to the PC port which the

USB cable is attached (in Step 4).

SERIAL RLC PROTOCOL COMMUNICATIONS

RLC Communications requires the Serial Communications Type Parameter

(tYPE) be set to “rLC”.

SENDING SERIAL COMMANDS AND DATA TO THE CONTROLLER

When sending commands to the controller, a string containing at least one command character must be constructed. A command string consists of a command character, a value identifier, numerical data (if writing data to the controller) followed by a command terminator character * or $.

N Node (Controller)

Address Specifier

T Transmit Value

(read)

V Value Change

R Reset Reset a register or output. Must be followed by

P Block Print

*, $ Terminator Signifies end of transmission

Command String Construction

The command string must be constructed in a specific sequence. The controller does not respond with an error message to invalid commands. The following procedure details construction of a command string:

1. The first characters consist of the Node Address Specifier (N) followed by a

2 character address number. The address number of the controller is

programmable. If the node address is 0, this command and the node address

itself may be omitted. This is the only command that may be used in

conjunction with other commands.

2. After the optional address specifier, the next character is the command

character.

3. The next character is the Register ID. This identifies the register that the

command affects. The P command does not require a Register ID character.

It prints according to the selections made in print options.

4. If constructing a value change command (writing data), the numeric data is

sent next.

5. All command strings must be terminated with the string termination

characters *, or $. The controller does not begin processing the command

string until this character is received. See Timing Diagram figure for

differences between terminating characters.

Address a specific controller. Must be followed by a two digit node address. Not required when address = 00.

Read a register from the controller. Must be followed by register ID character

Write to register of the controller. Must be followed by register ID character and numeric data.

Initiates a block print output. Registers are defined in programming.

Command String Examples:

1. Node address = 17, Write 350 to Alarm 1. String: N17VI350$

2. Node address = 5, Read Input value. String: N5TA*

3. Node address = 0, Reset Alarm 4 output. String: RL*

Sending Numeric Data

Numeric data sent to the controller must be limited to 4 digits (-1999 to

9999). Leading zeros are ignored. Negative numbers must have a minus sign.

The controller ignores any decimal point and conforms the number to the scaled resolution. (For example: the controller’s scaled decimal point position = 0.0 and 25 is written to a register. The value of the register is now 2.5.

Note: Since the controller does not issue a reply to value change commands,

follow with a transmit value command for readback verification.

RECEIVING DATA FROM THE CONTROLLER

Data is transmitted by the controller in response to either a transmit command (T), a print block command (P) or User Function print request. The response from the controller is either a full field transmission or an abbreviated transmission. The controller response mode is selected via the Abrv parameter in the Serial Port Parameters.

Full Field Transmission (Address, Mnemonic, Numeric data)

Byte Description

1, 2 2 byte Node Address field [00-99] 3 <SP> (Space) 4-6 3 byte Register Mnemonic field 7-18 2 byte data field, 10 bytes for number, one byte for sign, one byte for decimal point 19 <CR> carriage return 20 <LF> line feed 21 <SP>* (Space) 22 <CR>* carriage return 23 <LF>* line feed

* These characters only appear in the last line of a block print.

The first two characters transmitted are the node address, unless the node address assigned = 0, in which case spaces are substituted. A space follows the node address field. The next three characters are the register mnemonic.

The numeric data is transmitted next. The numeric field is 12 characters long (to accommodate the 10 digit totalizer), with the decimal point position floating within the data field. Negative values have a leading minus sign. The data field is right justified with leading spaces.

The end of the response string is terminated with a carriage return <CR> and <LF>. When block print is finished, an extra <SP><CR> <LF> is used to provide separation between the blocks.

Abbreviated Transmission (Numeric data only)

Byte Description

1-12 12 byte data field, 10 bytes for number, one byte for sign, one byte for decimal point 13 <CR> carriage return 14 <LF> line feed 15 <SP>* (Space) 16 <CR>* carriage return 17 <LF>* line feed

* These characters only appear in the last line of a block print.

Controller Response Examples:

1. Node address = 17, full field response, Input = 875

17 INP 875 <CR><LF>

2. Node address = 0, full field response, Alarm 2 = -250.5

SP2 -250.5<CR><LF>

3. Node address = 0, abbreviated response, Alarm 2 = 250, last line of block print

250<CR><LF><SP><CR><LF>

Auto/Manual Mode Register (MMR) ID: O

This register sets the controlling mode for the outputs. In Auto Mode (0) the controller controls the digital outputs and analog output. In Manual Mode (1) the outputs are defined by the registers DOR and AOR. When transferring from auto mode to manual mode, the controller holds the last output value (until the register is changed by a write). Each output may be independently changed to auto or manual.

O abcde

e = Analog Output

d = DO4

c = DO3

b = DO2

a = DO1

Example: VO11* places DO1-DO3 in Auto Mode; DO4 and Analog

Output in manual mode.

Analog Output Register (AOR) ID: Q

This register stores the present signal value of the analog output. The range of values of this register is 0 to 4095, which corresponds to the analog output range per the following chart:

Value

0 0.00 4.00 0.000

1 0.005 4.004 0.0025 2047 10.000 12.000 5.000 4094 19.995 19.996 9.9975 4095 20.000 20.000 10.000

Output Signal*

0-20 mA 4-20 mA 0-10 V

*Due to the absolute accuracy rating and resolution of the output card, the

actual output signal may differ 0.15% FS from the table values. The output signal corresponds to the range selected (0-20 mA, 4-20 mA or 0-10 V).

Writing to this register (VQ) while the analog output is in the Manual Mode causes the output signal level to update immediately to the value sent. While in the Automatic Mode, this register may be written to, but it has no effect until the analog output is placed in the manual mode. When in the Automatic Mode, the controller controls the analog output signal level. Reading from this register (TQ) will show the present value of the analog output signal.

Example: VQ2047 will result in an output of 10.000 mA, 12.000 mA or

5.000V depending on the range selected.

Digital Output Register (DOR) ID: S

This register stores the states of the setpoint outputs. Reading from this register (TS) will show the present state of all the digital outputs. A “0” in the setpoint location means the output is off and a “1” means the output is on.

S abcd

d = DO4

c = DO3

b = DO2

a = DO1

In Automatic Mode, the controller controls the digital output state. In Manual Mode, writing to this register (VS) will change the output state. Sending any character besides 0 or 1 in a field or if the corresponding output was not first in manual mode, the corresponding output value will not change.

Example: VS10* will result in output 3 on and outputs 1, 2 and 4 off.

Control Parameters Register (CTL) ID: M

This register contains the status (‘0’ = FALSE and ‘1’ = TRUE) of 8 control flags, in the form “abcdefgh” where:

a = Integral Lock b = Alternate PID Set(‘1’)/Primary PID Set(‘0’) c = Remote SP(‘1’)/Local SP(‘0’) d = SP2(‘1’)/SP1(‘0’) e = Setpoint Ramping Status(Read Only) f = Setpoint Ramping Disable g = Manual Mode (‘1’)/Auto Mode (‘0’) h = AutoTune

Example: a TM* response of “CTL 00011000” would indicate Setpoint 2

has been selected and the Setpoint is ramping. Sending VM10100* would leave Setpoint 2 selected and disable Setpoint ramping. All other control flags would be set to the FALSE (‘0’) state.

COMMAND RESPONSE TIME

The controller can only receive data or transmit data at any one time (halfduplex operation). When sending commands and data to the controller, a delay must be imposed before sending another command. This allows enough time for the controller to process the command and prepare for the next command.

At the start of the time interval t1, the computer program prints or writes the string to the com port, thus initiating a transmission. During t1, the command characters are under transmission and at the end of this period, the command terminating character (*) is received by the controller. The time duration of t1 is dependent on the number of characters and baud rate of the channel.

t1 = (10 * # of characters) / baud rate

At the start of time interval t2, the controller starts the interpretation of the command and when complete, performs the command function. This time interval t2 varies from 2 msec to 15 msec. If no response from the controller is expected, the controller is ready to accept another command.

If the controller is to reply with data, the time interval t2 is controlled by the use of the command terminating character and the (Serial Transmit Delay parameter (dLAY)). The standard command line terminating character is “*”. This terminating character results in a response time window of the Serial Transmit Delay time (dLAY) plus 15 msec. maximum. The dLAY parameter should be programmed to a value that allows sufficient time for the release of the sending driver on the RS485 bus. Terminating the command line with “$” results in a response time window (t2) of 2 msec minimum and 15 msec maximum. The response time of this terminating character requires that sending drivers release within 2 msec after the terminating character is received.

At the beginning of time interval t3, the controller responds with the first character of the reply. As with t1, the time duration of t3 is dependent on the number of characters and baud rate of the channel.

t3 = (10 * # of characters) / baud rate.

At the end of t3, the controller is ready to receive the next command. The maximum serial throughput of the controller is limited to the sum of the times t1, t2 and t3.

NO REPLY FROM CONTROLLER

RESPONSE FROM CONTROLLER

COMMUNICATION FORMAT

Data is transferred from the controller through a serial communication channel. In serial communications, the voltage is switched between a high and low level at a predetermined rate (baud rate) using ASCII encoding. The receiving device reads the voltage levels at the same intervals and then translates the switched levels back to a character.

The voltage level conventions depend on the interface standard. The table lists the voltage levels for each standard.

LOGIC RS232* RS485*INTERFACE STATE

1 TXD,RXD; -3 to -15 V a-b < -200 mVmark (idle) 0 TXD,RXD; +3 to +15 V a-b > +200 mVspace (active)

* Voltage levels at the Receiver

Data is transmitted one byte at a time with a variable idle period between characters (0 to ∞). Each ASCII character is “framed” with a beginning start bit, an optional parity bit and one or more ending stop bits. The data format and baud rate must match that of other equipment in order for communication to take place. The figures list the data formats employed by the controller.

Start bit and Data bits

Data transmission always begins with the start bit. The start bit signals the receiving device to prepare for reception of data. One bit period later, the least significant bit of the ASCII encoded character is transmitted, followed by the remaining data bits. The receiving device then reads each bit position as they are transmitted. Since the sending and receiving devices operate at the same transmission speed (baud rate), the data is read without timing errors.

Character Frame Figure

Parity bit

After the data bits, the parity bit is sent. The transmitter sets the parity bit to a zero or a one, so that the total number of ones contained in the transmission (including the parity bit) is either even or odd. This bit is used by the receiver to detect errors that may occur to an odd number of bits in the transmission. However, a single parity bit cannot detect errors that may occur to an even number of bits. Given this limitation, the parity bit is often ignored by the receiving device. The PAX2C controller ignores the parity bit of incoming data and sets the parity bit to odd, even or none (mark parity) for outgoing data.

Stop bit

The last character transmitted is the stop bit. The stop bit provides a single bit period pause to allow the receiver to prepare to re-synchronize to the start of a new transmission (start bit of next byte). The receiver then continuously looks for the occurrence of the start bit. If 7 data bits and no parity is selected, then 2 stop bits are sent from the PAX2C controller.

Preparation for Current, Volt, and Ohm Input Calibration

Warning: Input Calibration of this controller requires a signal source

capable of producing a signal greater than or equal to the range being calibrated with an accuracy of 0.01% or better.

Before starting, verify that the Input Range, T/V, and Excitation Jumper is set for the range to be calibrated. Verify that the precision signal source is connected and ready. Allow a 30 minute warm-up period before calibrating the controller. Selecting NO at any calibration step, will cause the controller to maintain the existing calibration parameters for that step. Selecting YES and pressing the P key will cause the controller to store new calibration settings for the range selected. Pressing D at any time will exit programming mode, but any range that has been calibrated will maintain the new settings.

* This parameter selection is affected by FlexCard installation. See Section 7.0,

Programming the FlexCard.

7.0 PrOgramming The fleXCard

It is recommended that the FlexCard programming be performed using Crimson.

A FlexCard provides an additional input type for use in the PAX2C. Depending on the FlexCard model, additional Parameters and Outputs may also be available. Section 7.0 subsections show the Parameter Programming Loops that become available, in the PAX2C, when a specific FlexCard is installed. Many of the Parameters function as defined in Section 6.0. FlexCard parameters that function the same as the corresponding PAX2C parameter have the same display, alarm, and output interface capability as the corresponding PAX2C parameter. Only the Parameters that do not appear in Section 6.0, or function differently, are defined in the following sections. For all menu parameters that are not defined, refer to the corresponding Parameter Programming Loop in section 6.0.

When making parameter selections, it is important to note the specific parameter and source of the parameter that is being selected. The parameter source identifier, when applicable, will appear in Line 2 Units location on the PAX2C display. If the parameter source is from the PAX2C, the identifier will be P2C, if from a FlexCard the identifier will be FCx (where x is the FlexCard address/slot location).

HEATER CURRENT MONITOR ALARM ACTION

The Heater Current Monitor Alarm Action (HCur) is useful for monitoring the

condition of external AC control circuitry via a Heater Current Monitor FlexCard. The alarm is assigned to the Process Value (current) measured on the input of the Heater Current Monitor card. The HEATER CURRENT MONITOR parameter in the HCM card Input programming provides for selection of the meter/controller output to be monitored (i.e. the output which actuates the heater control circuit). The state of this output, along with the measured PX2FCA1 card Process Value, determines when the Heater Current Monitor alarm activates.

The Alarm High Value (ALHI or H-x) is the value that represents the required

circuit-on current value. If the Heater Current Monitor card input measures a current less than the Alarm High Value during the ON state of the monitored output, the alarm becomes active.

The Alarm Low Value (ALLO or L-x) is the value that represents the allowable

circuit-off current. If the Heater Current Monitor card input measures a current greater than the Alarm Low Value during the OFF state of the monitored output, the alarm becomes active.

In both cases, the monitored output must be in the respective ON or OFF state

for a minimum of 1 second before the HCur alarm will activate. This delay prevents false alarm triggering due to brief power glitches in the heater circuit during switching. Additional on/off delay can be added by increasing the tON/ tOFF parameters.
