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. 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. DIMENSIONS In inches (mm) 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. 3.80 (96.52) 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 1.95 (49.53) 0.10 (2.54) 4.14 (105.16) Note: To determine dimensions for horizontal units, swap height and width.

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 PANEL case. The panel latch should be engaged in the farthest forward slot possible. To achieve a proper BEZEL seal, tighten the latch screws evenly until the unit is snug in the panel (Torque to approximately 7 in-lbs [79N-cm]). Do not over-tighten the screws. 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. HORIZONTAL PANEL CUT-OUT LATCHING SLOTS PANEL LATCH 3.62 +.03 -.00 (92 +.8 -.0 ) LATCHING TABS 1.77+.02 -.00 (45 +.5 -.0 ) PANEL GASKET PANEL MOUNTING 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. 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 FRONT DISPLAY 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. Main Circuit Board 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.

For proper operation, the input range selected in programming must match the jumper setting. 2A .25 A .025 A .0025 A 250 μA THERMOCOUPLE/ VOLTAGE SELECTION LV - 250mV/2V/100Ω/1KΩ M - 10V/100V HV - 25V/200V/10KΩ TEMPERATURE VOLTAGE CURRENT INPUTS VOLTAGE/RESISTANCE INPUTS REAR TERMINALS 6 This document provided by Barr-Thorp Electric Co., Inc. 800-473-9123 www.barr-thorp.com 3.0 INSTALLING PLUG-IN CARDS The plug-in cards are separately purchased optional cards that perform specific functions. These cards plug into the main circuit board of the controller. The plug-in cards have many unique functions when used with the PAX2C. CAUTION: The plug-in card and main circuit board contain static sensitive components. Before handling the cards, discharge static charges from your body by touching a grounded bare metal object. Ideally, handle the cards at a static controlled clean workstation. Also, only handle the cards by the edges. Dirt, oil or other contaminants that may contact the cards can adversely affect circuit operation. Alignment Slots To Install: 1. With the controller removed from the case, locate the plug-in card connector for the card type to be installed. 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. Internal Supply (18 V unregulated) External Supply (30 V max ) TOP VIEW Main Circuit Board Analog Output Card Connectors Setpoint Output Card Serial Communications Card 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. Finger Tab Finger Tab 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 this controller is designed with a high degree of immunity to Electro-Magnetic 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 the controller may be different for various installations. The controller becomes more immune to EMI with fewer I/O connections. Cable length, routing, and shield termination are very important and can mean the difference between a successful or troublesome installation. Listed below are some EMC guidelines for successful installation in an industrial environment. 1. The controller should be mounted in a metal enclosure, which is properly connected to protective earth. 2. Use shielded (screened) cables for all Signal and Control inputs. The shield (screen) pigtail 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 only at the panel where the unit is mounted to earth ground (protective earth). b. Connect the shield to earth ground at both ends of the cable, usually when the noise source frequency is above 1 MHz. c. Connect the shield to common of the controller and leave the other end of the shield unconnected and insulated from earth ground. 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 in 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. 4. Signal or Control cables within an enclosure should be routed as far as possible from contactors, control relays, transformers, and other noisy components. 5. In extremely high EMI environments, the use of external EMI suppression devices, such as ferrite suppression cores, is effective. Install them on Signal and Control cables as close to the unit as possible. Loop the cable through the core several times or use multiple cores on each cable for additional protection. Install line filters on the power input cable to the unit to suppress power line interference. Install them near the power entry point of the enclosure. The following EMI suppression devices (or equivalent) are recommended: Ferrite Suppression Cores for signal and control cables: Fair-Rite # 0443167251 (RLC# FCOR0000) TDK # ZCAT3035-1330A Steward # 28B2029-0A0 Line Filters for input power cables: Schaffner # FN2010-1/07 (RLC# LFIL0000) Schaffner # FN670-1.8/07 Corcom # 1 VR3 Note: Reference manufacturer’s instructions when installing a line filter. 6. Long cable runs are more susceptible to EMI pickup than short cable runs. Therefore, keep cable runs as short as possible. 7. Switching of inductive loads produces high EMI. Use of snubbers across inductive loads suppresses EMI.

The eight segment bar graph may be mapped to values such as Output Power, Deviation or Setpoints. The three digit units mnemonic characters can be used to indicate which Line 1 display value is shown. Line 1 is a tri-colored display and may be configured to change color based on specified alarm/logic configurations. Line 2 consists of a 4-digit bottom line display, eight segment bar graph and a three digit units mnemonic. Values such as Setpoints, Output Power, Deviation, PID Parameters/Tuning Status, List A/B Status, and Alarm Values may be shown on the Line 2 display. The eight segment bar graph may be mapped to values such as Output Power, Deviation or Setpoints. The three digit units mnemonic characters can be used to indicate which Line 2 display value is shown. Line 2 is a tri-colored display and may be configured to change color based on specified alarm/logic configurations. The display loops described in the next section are used to view, reset and modify the selected display values, based on the Line 2 Value Access setting programmed for each available value. See Line 2 parameters in the Display Parameters programming section for configuration details. 9 This document provided by Barr-Thorp Electric Co., Inc. 800-473-9123 www.barr-thorp.com Universal Annunciator Zones Manual Mnemonic The PAX2C has four programmable universal annunciator zones. Each zone has a user-defined two digit annunciator mnemonic to suit a variety of applications. Universal annunciator zones are tri-colored and may be configured to change color based on specified alarm/logic configurations. ‘MAN’ - Flashes when the unit is in manual mode The Mnemonic zone is tri-colored and may be configured to change color based on specified alarm/logic configurations. LINE 2 DISPLAY LOOPS The PAX2C offers three display loops to allow users quick access to needed information.

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. P ProNO Pro End Full Programming Mode 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: 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 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. 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. 10 This document provided by Barr-Thorp Electric Co., Inc. 800-473-9123 www.barr-thorp.com SELECTION/VALUE ENTRY P 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. D Pro NO F1 Analog Input Setup Parameters INPt D AnLG P Pro 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.

ROUNDING INCREMENT rnd SQUARE ROOT Root YES NO 2 20 5 50 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. 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 ǻP , where ǻP = 0 - 500 PSI, transmitted linearly by a 4 - 20 mA transducer. At full flow rate ( ǻP = 500 PSI), the flow is 6216 ft3/h.

The default factory 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 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). 13 This document provided by Barr-Thorp Electric Co., Inc. 800-473-9123 www.barr-thorp.com 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 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. USEr-n will represent both user inputs.

The value is entered in units/time. A value of 0 disables setpoint ramping. If the Setpoint Ramp Rate is a non-zero value, and the Actual Setpoint is changed or the controller is powered up, the controller sets the Target Setpoint to the current process measurement, and uses that value as its setpoint. It then adjusts the Target Setpoint according to the setpoint Ramp Rate. When the Target Setpoint reaches the Actual Setpoint, the controller resumes use of the Actual Setpoint value. (In a properly designed and functioning system, the process will have followed the Target Setpoint value to the Actual Setpoint value.) 0. 0 32 This document provided by Barr-Thorp Electric Co., Inc. 800-473-9123 www.barr-thorp.com PID PARAMETERS: PID PARAMETERS (Pid) Pro NO F1 F2 Pro Pid Pid P D Pid Pid Pri SEL PID Parameter Selection ProP Intt dErt FLtr OPOF ProP Intt dErt FLtr OPOF 4. 0 120 30 1. 0 1. 0 4. 0 120 30 1. 0 0. 0 Pri Primary Proportional Band Value Pri Primary Integral Time Value Pri Primary Derivative Time Value Pri Primary Power Filter Value Pri Primary Output Offset Value PID PARAMETER SELECTION Pid Pri ALt Select the desired set of PID Values (Primary or Alternate) that will be used in the PID calculation.

Pri 0 to 999.9 % The Proportional Band property, entered as a percentage of the full input range, is the amount of input change required to vary the output full scale. For temperature inputs, the input range is fixed per the entered thermocouple or RTD type. For process inputs, the input range is the difference between the Process at 0%, and Process at 100% values. The Proportional Band is adjustable from 0.0% to 999.9%, and should be set to a value that provides the best response to a process disturbance while minimizing overshoot. A Proportional Band of 0.0% forces the controller into On/Off Control with its characteristic cycling at setpoint. The optimal value may be established by invoking Auto-tune. 4. 0 ALt Alternate Proportional Band Value Alternate Integral Time Value ALt Alternate Derivative Time Value FLtr 120 1. 0 Alternate Output Offset Value The Power Filter is a time constant, entered in seconds, that dampens the calculated output power. Increasing the value increases the dampening effect. Generally, a Power Filter in the range of onetwentieth to one-fiftieth of the controller’s integral time (or process time constant) is effective. Values longer than these may cause controller instability due to the added lag effect. PRIMARY/ALTERNATE OUTPUT OFFSET OPOF 0. 0 -100.0 to 100.0 This value effectively shifts the zero output point of the module’s output power calculation. This feature is most commonly used in proportional-only applications to remove steady-state error. 0 to 65000 seconds The Integral Time is the time in seconds that it takes the integral action to equal the proportional action, during a constant process error. As long as the error exists, integral action is repeated each Integral Time. The higher the value, the slower the response. The optimal value may be established by invoking autotune.

As long as the ramping error exists, the derivative contribution is repeated every derivative time. Increasing the value helps to stabilize the response. Too high of a value, coupled with noisy signal processes, may cause the output to fluctuate too greatly, yielding poor control. Setting the time to zero disables derivative action. The optimal Derivative Time may be established by invoking auto-tune. 30 33 This document provided by Barr-Thorp Electric Co., Inc. 800-473-9123 www.barr-thorp.com PID PARAMETERS: OUTPUT POWER PARAMETERS (PWr) Pro NO F1 F2 Pro Pid Pid P D PWr FLtP dEAd HtGn HtLo HtHi CLGn CLLo CLHi 50. 0 0. 0 100. 0 0. 0 100. 0 100. 0 0. 0 100. 0 Heat Power High Limit Output Cool Gain °/o Fault Condition Power Value °/o Output Deadband °/o Output Heat Gain °/o Heat Power Low Limit °/o FAULT CONDITION POWER VALUE FLtP -199.9 to 200.0 % Enter the desired control output value for the controller to assume in the event that the input sensor fails.

The hysteresis value is centered around the setpoint, that is, the transition points of the output will be offset above and below the setpoint by half of the On/Off Hysteresis value. This value effects outputs programmed for Heat or Cool. During auto-tune, the controller cycles the process through 4 on/off cycles, so it is important to set the On-Off Hysteresis to an appropriate value before initializing auto-tune. 0. 2 ON/OFF DEADBAND dEAd -199.9 to 999.9 units The On-Off Deadband property provides a means of offsetting the on-points of heat and cool outputs programmed for on/off operation.

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 $. Command Chart Register Identification Chart ID VALUE DESCRIPTION MNEMONIC APPLICABLE COMMANDS/COMMENTS A Signal Input INP B Active Setpoint SET T, P T, V, P C Setpoint Ramp Rate RMP T, V, P D Output Power PWR T, V, P (V only in manual mode) E Proportional Band PBD T, V, P F Integral Time INT T, V, P G Derivative Time DER T, V, P H Alarm Status (1-4) ALR T, R, P COMMAND DESCRIPTION NOTES I Alarm Value 1 AL1 N Node (Meter) Address Specifier Address a specific meter. Must be followed by a two digit node address. Not required when address = 00. J Alarm Value 2 AL2 T, V, R, P (Reset command resets Alarm Outputs) K Alarm Value 3 AL3 L Alarm Value 4 AL4 M Control Parameters CTL T, V, P Auto/Manual Register MMR T, V T Transmit Value Read a register from the meter. Must be followed (read) by register ID character V Value Change (write) Write to register of the meter. Must be followed by register ID character and numeric data. O Q Analog Output Register AOR T, V R Reset Reset a register or output. Must be followed by register ID character. S Digital Output Register DOR T, V P Block Print Request Initiates a block print output. Registers are defined in programming. *, $ 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 $. The meter does not begin processing the command string until this character is received. See Timing Diagram figure for differences between terminating characters. Command String Examples: 1. Node address = 17, Write 350 to Alarm 1. String: N17VI350$ 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 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. 43 This document provided by Barr-Thorp Electric Co., Inc. 800-473-9123 www.barr-thorp.com RECEIVING DATA FROM THE CONTROLLER Analog Output Register (AOR) ID: Q 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. 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: Full Field Transmission (Address, Mnemonic, Numeric data) Byte Description 1, 2 3 4-6 7-18 2 byte Node Address field [00-99] <SP> (Space) 3 byte Register Mnemonic field 2 byte data field, 10 bytes for number, one byte for sign, one byte for decimal point <CR> carriage return <LF> line feed <SP>* (Space) <CR>* carriage return <LF>* line feed 19 20 21 22 23 * 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. Output Signal* Register Value 0-20 mA 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 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. Abbreviated Transmission (Numeric data only) S abcd Byte Description 1-12 12 byte data field, 10 bytes for number, one byte for sign, one byte for decimal point <CR> carriage return <LF> line feed <SP>* (Space) <CR>* carriage return <LF>* line feed 13 14 15 16 17 * 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> 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. 44 This document provided by Barr-Thorp Electric Co., Inc. 800-473-9123 www.barr-thorp.com COMMAND RESPONSE TIME Timing Diagrams 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. NO REPLY FROM CONTROLLER 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. RESPONSE FROM CONTROLLER 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. 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 INTERFACE STATE RS232* RS485* 1 mark (idle) TXD,RXD; -3 to -15 V a-b < -200 mV 0 space (active) TXD,RXD; +3 to +15 V a-b > +200 mV * Voltage levels at the Receiver Character Frame Figure Data is transmitted one byte at a time with a variable idle period between characters (0 to f). 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. 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. 45 This document provided by Barr-Thorp Electric Co., Inc. 800-473-9123 www.barr-thorp.com FACTORY SERVICE OPERATIONS (FACt) Pro FACTORY SERVICE CODE NO COdE 0 to 250 FCS 50 F1 Enter the Service Code for the desired operation.

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. FCS 50 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. The controller will briefly display the model (P2C) on Line 1, and the current firmware version (UEr x.xx) on Line 2, and then return to COdE 50. 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 unit to maintain the existing calibration parameters for that step.

Warning: RTD Input Calibration of this controller requires a signal source capable of producing a 300 ohm resistance with an accuracy of 0.01% or better. Before starting, verify that the T/V Jumper is in the T position. Verify the RTD jumper is in the proper range. Verify 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 unit to maintain the existing calibration parameters for that step. Selecting YES and pressing P key will cause the unit 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. 6. Place the thermocouple in close thermal contact to a reference thermometer probe. (Use a reference thermometer with an accuracy of 0.25% °C or better.)

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). 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. CONTROL MODE EXPLANATIONS ON/OFF CONTROL ON/OFF CONTROL - HEAT/COOL OUTPUT FIGURES 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.

The Proportional Band is set to 0.0 and the Relative Gain in Cooling to 0.0. The Deadband in Cooling sets the amount of operational deadband or overlap between the outputs. The setpoint and the On/Off Control Hysteresis applies to both O1 and O2 outputs. The hysteresis is balanced in relationship to the setpoint and deadband value.

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. 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. TYPICAL PID RESPONSE CURVE P&I P&I&D INPUT 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. SP P&D P only AUTOMATIC CONTROL MODE TIME 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. 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 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. OUTPUT POWER (%) 100 Digital Output REVERSE ACTING DIRECT ACTING P-BAND P-BAND HEATING COOLING 0 Digital Output TEMPERATURE SETPOINT 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. 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”. 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 49 This document provided by Barr-Thorp Electric Co., Inc. 800-473-9123 www.barr-thorp.com Note: The Proportional band shift due to integral action may itself be “reset” by temporarily setting the controller to the on/off control mode (proportional band = 0). DEVIATION TIME DEVIATION TIME OUTPUT POWER (%) PROPORTIONAL OUTPUT OUTPUT POWER (%) DERIVATIVE OUTPUT INTEGRAL OUTPUT TIME PROPORTIONAL OUTPUT TIME NOTE: TOTAL OUTPUT POWER IS CALCULATED BASED ON THE THREE PID SETTINGS. NOTE: TOTAL OUTPUT POWER IS CALCULATED BASED ON THE THREE PID SETTINGS. DERIVATIVE TIME INTEGRAL TIME PRIMARY/ALTERNATE PID VALUES 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. 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. PID TUNING EXPLANATIONS AUTO-TUNE INITIATE 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. 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.

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.

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.

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. 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. 51 This document provided by Barr-Thorp Electric Co., Inc. 800-473-9123 www.barr-thorp.com TROUBLESHOOTING GUIDE PROBLEM REMEDIES No Display At Power-Up Check power level and power connections No Display After Power-Up Check dLEU and dCnt program settings in the Display menu.
