DESCRIPTION

The PAX2C Temperature/Process Controller offers many features and performance capabilities to suit a wide range of applications. The PAX2C has a universal input to handle various input signals including Temperature, DC Voltage/Current and Resistance. Optional plug-in cards allow the opportunity to configure the controller for present applications, while providing easy upgrades for future needs. The PAX2C employs a tri-color display with seven independently programmable color zones.

The controller has been specifically designed for harsh industrial environments. With NEMA 4X/IP65 sealed bezel, CE compliance and extensive testing of noise effects, the controller provides a tough reliable application solution.

MAIN CONTROL

The controller operates in the PID Control Mode for both heating and cooling, with on-demand auto-tune that establishes the tuning constants. The PID tuning constants may be fine-tuned and then locked out from further modification. The controller employs a unique overshoot suppression feature, that allows the quickest response without excessive overshoot. Switching to Manual Mode provides the operator direct control of the output.

DISPLAY

The PAX2C features a dual line display with units annunciators, dual bar graphs, four universal annunciators and tri-color capability. Each of the seven display zones may be configured independently of the others, providing a visual indication of control and/or alarm status.

ALARMS

The PAX2C has up to sixteen “soft” alarms that may be configured to suit a variety of control and alarm requirements. These alarms may be used to monitor and/or actuate the controller’s physical outputs as well as change display colors. Mapped “soft” alarms may be processed independently or logically combined using AND/OR Boolean logic.

OPTION CARDS

Optional plug-in cards provide dual FORM-C relays, quad FORM-A, quad sinking, or quad sourcing open collector logic outputs. These cards can be used as control outputs or for alarm indication.

A linear DC output signal is available as an optional plug-in card. The card provides either 20 mA or 10 V signals. The output can be scaled independent of the input range and can track the input, max and min readings or for control.

Communication and bus capabilities are also available as option cards. These include RS232, RS485, DeviceNet, and ProfibusDP. The PAX2C can be

programmed to utilize Modbus protocol. With Modbus, the user has access to most configuration parameters. Readout values, setpoint, process and alarm values can be controlled through the bus. Additionally, the controller has a feature that allows a remote computer to directly control the outputs of the controller.

With a Windows® based program, made available by Red Lion Controls, configuration data can be downloaded to the PAX2C via a built-in USB programming port.

Installation

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

While holding the unit in place, push the panel

latch over the rear of the unit 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

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 unit should be installed in a location that does not exceed the operating temperature and provides good air circulation. Placing the unit 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 unit.

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.

The types are keyed by position with different main circuit board connector locations. When installing the card, hold the controller by the rear terminals and not by the front display board. If installing the Quad sourcing Plug-in Card (PAXCDS40), set the jumper for

internal or external supply operation before continuing.

2. Install the plug-in card by aligning the card terminals with the slot bay in the rear cover. Be sure the connector is fully engaged and the tab on the plug-in card rests in the alignment slot on the display board.

3. Slide the controller base back into the case. Be sure the rear cover latches fully into the case.

4. Apply the plug-in card label to the bottom side of the controller in the designated area. Do Not Cover the vents on the top surface of the controller. The surface of the case must be clean for the label to adhere properly.

4.0 Wiring The COnTrOller

WIRING OVERVIEW

Electrical connections are made via screw-clamp terminals located on the back 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 against those shown in wiring drawings for proper wire position. Strip the wire, leaving approximately 0.3" (7.5 mm) bare lead exposed (stranded wires should be tinned with solder). Insert the lead under the correct screw-clamp terminal and tighten until the wire is secure (Pull wire to verify tightness). Each terminal can accept up to one #14 AWG (2.55 mm) wire, two #18 AWG (1.02 mm), or four #20 AWG (0.61 mm).

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

unit is mounted.

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

the noise source frequency is over 1 MHz.

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 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 sequence 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 and perform the user functions programmed in the User Input parameter section.

Parameter and Hidden Parameter Display Loops

Display loops provide quick access to selected parameters that can be viewed and modified on Line 2 without having to enter Full Programming mode. These values may include: input, max/min, List A/B selection, output power, PID parameters/control, alarm parameters, setpoint values/selection, and display intensity and contrast settings. To utilize the Parameter or Hidden Parameter display loops, 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. 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 meter 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 recommended that program settings be recorded as programming is

performed. A blank Parameter Value Chart is provided at the end of this bulletin.

BASIC/ADVANCED MODE

The PAX2C incorporates two different configuration modes that are user

selectable via the Display Configuration Menu:

Basic Mode (bSIC)

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

Advanced Mode (AdUC)

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 display color changes are desired.

PROGRAMMING MODE ENTRY

The Programming Mode is entered by pressing the P key. Full Programming Mode will be accessible unless the controller is programmed to use the Parameter loop or Hidden Parameter loop on the Line 2 display. 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 Mode 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.

MODULE ENTRY

The Programming Menu is organized into seven modules. These modules group together parameters that are related in function. The  and  keys are used to select the desired module. The displayed module is entered by pressing the P key.

MODULE MENU

Upon entering a module, a parameter selection sub-menu is provided to choose the specific parameter type for programming. For example, this includes analog and user input under the Input Parameter menu. Use the  and  keys to select the desired parameter type, and press the P key to enter the parameter menu.

PARAMETER MENU

Upon entering the Parameter Menu, the P key is pressed to advance to a specific parameter to be changed. After completing the parameter menu, or upon pressing the D key, the display returns to the initial entry point for the parameter menu. For each additional press of the D key, the display returns to the previous level within the module until exiting the module entirely.

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 meter to the next parameter.

Numerical Value Entry

If the parameter is programmed for enter (Entr), the ! and @ keys are used to change the parameter values in any of the display loops.

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 meter 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 recommended to start with the Input Parameters and proceed through each module in sequence. If lost or confused while programming, press and hold the D key to exit programming mode and start over. It is recommended that program settings be recorded as programming is performed. When programming is complete 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.

SQUARE ROOT

Root

INP

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 unit to be used in applications in which the measured signal is the square of the PV. This is useful in applications such as the measurement of flow with a differential pressure transducer.

entered points up to the limits of the Input Signal Jumper position. Each scaling point has a coordinate-pair consisting of an Input Value (INPt n) and an associated desired Display Value (dISP n).

Linear - Scaling Points (2)

For linear processes, only 2 scaling points are necessary. It is recommended that the 2 scaling points be at opposite ends of the input signal being applied. The points do not have to be the signal limits. Display scaling will be linear between and continue past the

2 to 16

Nonlinear - Scaling Points (Greater than 2)

For non-linear processes, 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 Input Display will be linear between scaling points that are sequential in program order. Each scaling point has a coordinate-pair consisting of an Input Value (INPt n) and an associated desired Display Value (dISP n). Data from tables or equations, or empirical data could be used to derive the required number of segments and data values for the coordinate pairs. In the Crimson software, several linearization equations are provided to help calculate scaling points.

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. USEr-n will represent both user inputs. Fn will represent both function keys and second function keys.

display parameTers: line 2 parameTers (LOCS)

This section details programming for the Line 2 (Bottom Line) Display. Various Input, Display, PID, Alarm, and Function Parameters can be shown on the Line 2 display. The display loops described below are used to view, reset and modify the selected display values, based on the Line 2 Value Access setting programmed for each available value.

Main Display Loop

In the Main display loop, the selected values can be consecutively read on Line 2 by pressing the D key. The lower 3-character units mnemonic indicates which Line 2 value is currently shown. When in the Main display loop, the Function keys  and  perform the User functions programmed in the User Input program section.

Parameter Display Loop and Hidden Parameter Loop

These display loops provide quick access to selected parameters that can be viewed and modified on Line 2 without having to enter Full Programming Mode. To utilize the Hidden Parameter display loop, a security code (1-250) must be programmed. (See Security Code Configuration at the end of this section.)The Parameter display loop is accessed by pressing the P key. 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 loop follows the Parameter display loop, and can only be accessed when the correct security code is entered at the Code prompt.

serial COmmuniCaTiOns

The PAX2 supports serial communications using the optional serial communication cards or via the USB programming port located on the side of the unit. 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 the RLC protocol and also supports Modbus communications. The PAX Modbus option card should not be used with the PAX2, as the PAX2 internal Modbus protocol supports complete unit 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. Insure 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 MODBUS COMMUNICATIONS

Modbus Communications requires that the Serial Communications Type Parameter (tYPE) be set to Modbus RTU (rtu) or Modbus ASCII (ASC).

PAX2 CONFIGURATION USING CRIMSON AND SERIAL COMMUNICATIONS CARD

1. Install Crimson software.

2. Install RS232 or RS485 card and connect communications cable from PAX2

to PC.

3. Supply power to PAX2.

4. Configure serial parameters as Modbus RTU (rtu), 38,400 baud, address

SERIAL RLC PROTOCOL COMMUNICATIONS

RLC Communications requires the Serial Communications Type Parameter

(tYPE) be set to “rLC”.

SENDING SERIAL COMMANDS AND DATA TO THE METER

When sending commands to the meter, 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 meter) followed by a command terminator character * or $.

N Node (Meter)

Address Specifier

T Transmit Value

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

P Block Print

Request

*, $ Terminator Signifies end of transmission

Command String Construction

The command string must be constructed in a specific sequence. The meter

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 meter 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 meter does not begin processing the command string until this character is received. See Timing Diagram figure for differences between terminating characters.

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

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

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

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 meter’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>

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. (It is not necessary to send least significant 0s.)

Example: VS10* will result in output 1 on and output 2 off.

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. In a write command string (VO), any character besides 0 or 1 in a field will not change the corresponding output mode.

O abcde

e = Analog Output

d = DO4

c = DO3

b = DO2

a = DO1

Example: VO00011* places DO4 and Analog in manual.

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.

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 PAX 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 PAX controller.

The controller has been fully calibrated at the factory. Scaling to convert the input signal to a desired display value is performed in Input Parameters. If the controller appears to be indicating incorrectly or inaccurately, refer to Troubleshooting before attempting to calibrate the controller. When recalibration is required (generally every 2 years), it should only be performed by qualified technicians using appropriate equipment. Calibration does not change any user programmed parameters. However, it will affect the accuracy of the input signal and the values previously stored using the Apply (APLY) Scaling Style.

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 verify 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 (E-XX) 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.

PROCESS START-UP

After starting the process, the controller’s PID settings must be initially “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 can be tuned once, but must be re-tuned if the process has been changed significantly. 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 this control mode, 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 replacement, the PID settings from the unit being replaced may be used as good initial values. Be sure to consider any differences in the units and the PID settings when replacing. 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 control modes are saved to provide a quick and predictable process response on the next power-up. When powering down the process, it is important to power down the controller at the same time. This prevents the reset action of the controller from shifting the proportional band while the temperature/process value is dropping and prevents excessive overshoot on the next process start-up.

PID CONTROL

P & I

In PID Control, the controller processes the input and then calculates a control output power value by use of a specialized Proportional Band, IntegralTime, and Derivative Time control algorithm. The system is controlled with the new 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 both used. The PID parameters can be established by using Auto-Tune, or they can be Manually tuned to the process.

TIME

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.

LINEAR PID CONTROL

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

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 adjusts the percentage of power through the % Power display to control the output power. 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 are ignored when the controller is in Manual.

MODE TRANSFER

When transferring the controller 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.

AUTOMATIC CONTROL MODE

In Automatic Control Mode, the percentage of output power is automatically determined by PID or On/Off calculations based on the setpoint and process feedback.

pid COnTrOl

PROPORTIONAL BAND

Proportional band is defined as the “band” of temperature 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 percent of input sensor range.

Example: Thermocouple type T with a temperature range of 600°C is used and

is indicated in degrees Celsius with a proportional band of 5%. This yields a

band of 600°C X 5% = 30°C.

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).

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. This parameter appears in unprotected parameter mode when integral time is set to zero. The controller has the feature to prevent integral action when operating outside the proportional band. This prevents “reset wind-up”.

DERIVATIVE TIME

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 too greatly, yielding poor control. None or too little derivative action usually results in decreased stability with higher overshoots. No derivative action usually requires a wider proportional and slower integral times to maintain the same degree of stability as with derivative action. Derivative action is disabled by setting the time to zero.

pid Tuning eXplanaTiOns

AUTO-TUNE

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 upon 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 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 start-up, from 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.

TEMPERATURE

PRIMARY/ALTERNATE PID VALUES

The PAX2C incorporates two different groups of PID parameters in memory.

These are designated as the Primary (Pri) and Alternate (Alt) PID values. It is possible to toggle between these values using the PID Selection parameter which is available in the PID configuration menu. This functionality (PSEL) is also available via the user inputs, function keys or Line 2 user function.

The Active 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 selected by the PSEL parameter.

INITIATE AUTO-TUNE

Below are the parameters and factory settings 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 outputs prior to initiating auto-tune.

AUTO-TUNING CODE FIGURE

TIME

AUTO-TUNE PROGRESS

The controller will oscillate the controlling output(s) for four phases. The bottom display will flash the phase number. Parameter viewing is permitted during Auto-Tune. The time to complete the Auto-Tune cycles 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 AutoTune unusually long, there may be a process problem. Auto-Tune may be stopped by entering NO in Auto-Tune Start tUNE.

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

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

In some unusual 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 10.0% for temperature models

(Temperature) and 100.0% for process models (Voltage/Current).

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

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

4. Set the Output Cycle Time (CYCt) in the Digital Output Menu to no higher

than one-tenth of the process time constant (when applicable).

5. Place the controller into Manual Control Mode (MAN) via the trnF parameter

in the PID Menu 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 DEFEAT 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 via the trnF parameter

in the PID Menu. 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 Dampening Time to 1/40 (0.025) the period of the oscillation.
