VersaPro Temperature Controller 1. Page 7 Safety and Environment Information Please read this section carefully before installing the controller This instrument is intended for industrial applications used in conjunction with Marathon Monitors zirconia oxygen sensors and standard thermocouple types. It is assumed that any installation meets either CE standards for industrial safety or NEC standard wiring practices.
PAGE 8
VersaPro Temperature Controller 2.3 Page 8 Enclosure of live parts To prevent hands or metal tools touching parts that may be electrically live, the controller should be installed in an enclosure. The contacts on the rear of the instrument case or finger save but it is still possible for loose wiring, or metal objects to come in contact with live terminal connections. It is recommended that power be removed from the instrument connections before they are disconnected.
PAGE 9
VersaPro Temperature Controller 2.9 Page 9 Voltage rating The maximum continuous voltage applied between any of the following terminals must not exceed 250VAC:  line or neutral to any other connection;  relay output to logic, dc or sensor connections;  any connection to ground. The controller should not be wired to a three phase supply with an unearthed star connection. Under fault conditions in this supply could rise above 264VAC with respect to ground and the product would not be safe.
PAGE 10
VersaPro Temperature Controller 2.12 Page 10 Grounding of the temperature sensor shield In some installations it is common practice to replace the temperature sensor while the controller is still powered up. Under these conditions, as additional protection against electric shock, we recommend that the shield of the temperature sensor be grounded at one end of the wire. Do not rely on grounding through the framework of the machine. 2.
PAGE 11
VersaPro Temperature Controller 4 Page 11 Installation The VersaPro instrument is designed for up to 1/8" panel mounting in a DIN standard opening of 3.62" square (adapter panels available by special order). Required rear clearance is 7.5” to allow for wiring. As with all solid state equipment, the controller should be located away from excessive heat, humidity, and vibration.
PAGE 12
VersaPro Temperature Controller Page 12 Figure 2 Wiring Schematic 4.1 Mounting To mount the instrument in a control panel, a hole must be cut 3.62" square in the necessary location on the panel. The following procedure should be followed to mount the VersaPro in the panel. 1) Insert the unit into previously cut out 3.62" square hole in panel. 2) While supporting unit, insert one clamping bracket into the groove on the bottom of unit, and then install the 6-32 set screw.

VersaPro Temperature Controller 5 Page 13 Process Control Options The Versapro is configured to perform as a single loop PID controller for a specific process. This instrument is setup as an oxygen controller. Table 1 Instrument Control Options Function Temperature Linear Input A Linear Input B 6 Description Uses the temperature signals from a thermocouple to control to temperature setpoint.
PAGE 14
VersaPro Temperature Controller 6.2 Page 14 Time Proportioning Dual (TD) This mode is used when there are two processes to control that have complementary effects; like heat and cool. The time proportioning dual mode uses two control outputs; one for heat and one for cool. There is never a time when both outputs are on simultaneously. The control loop computes a percent output from -100 to +100%. When positive, the proportioning action applies to the forward output.
PAGE 15
VersaPro Temperature Controller Page 15 Deadband allows the process to deviate away from the setpoint by the width of the deadband before any control action occurs. The deadband is adjusted through the Proportional Band in units of the displayed setpoint value. The reset and rate values have no effect in ON/OFF control. Let’s assume the process setpoint is 1500° with a proportional band of 5. This represents a deadband of 5°, which is a band of ±5° around setpoint.
PAGE 16
VersaPro Temperature Controller 6.9 Page 16 Direct or Reverse Control Action Control action determines how the output of the controller will react to effect a change on the process. The control action is considered ‘direct’ if an increase in the output produces an increase in the process value. A ‘reverse’ control action would be when an increase in the output produces a decrease in the process.

PAGE 18
VersaPro Temperature Controller Page 18 Output Low An alarm is generated any time the control percent output drops below the alarm value. The alarm setting is minimum percent output allowed. Fault An alarm is generated any time an open input occurs on the T/C input. The input is pull up to a maximum value if no input is connected or if the input fails in an open circuit mode. The center display will indicate which of these conditions has caused the alarm.
PAGE 19
VersaPro Temperature Controller 7.3 Page 19 Alarm Delay Times Each alarm can have delay ON, delay OFF, or both delays applied. Delays can be applied in increments of a second, up to a maximum of 250 seconds. ON delays are helpful if a known upset in the process can be ignored. This avoids nuisance alarms but still maintains an active alarm if the alarm condition persists following the delay.
PAGE 20
VersaPro Temperature Controller 8 Page 20 Serial Interface The VersaPro has a single RS-485 half duplex (two wire) communications port. This port can be configured for either the Marathon protocol of Modbus RTU protocol. Baud rates and parities are selectable. The Modbus protocol only uses a parity of none. See the section on communications for details on both of these protocols. The Versapro can be connected to networks with up to 128 similar devices.

PAGE 32
VersaPro Temperature Controller 10 Page 32 Digital Input Event The VersaPro has a single digital input. This input is activated by making an isolated contact closure between terminals TB-B 11 and 12. This input is debounced for a momentary closure of at least 0.6 seconds. NOTE Do not connect either terminals TB-B 11 or 12 to any AC or DC potentials. These terminals are internally connected to an isolated 5VDC source. Use only an isolated contact closure across these terminals.
PAGE 33
VersaPro Temperature Controller Page 33 Strt (controller only) This selection will start the timer function if the timer is enabled, the setpoint is greater than 0, and one alarm contact is assigned to a timer function. HOLd (controller only) This selection will place the timer in a hold state for as long as the event input is active. End (controller only) This selection will acknowledge the end condition of the timer, clear the end state, and reset the timer for another start.
PAGE 34
VersaPro Temperature Controller 11 Page 34 Timer Function The Versapro timer function is available on all process controller options. The timer can operate independently or it can be dependent on the process based on how either alarm contact is configured. The instrument has three possible functions; timer, guaranteed start timer, and guaranteed soak timer. These functions are set through the mode selection of alarm 1 or alarm 2 in the Setup menu.
PAGE 35
VersaPro Temperature Controller Page 35 The Rem LED on the front panel will flash while the timer is active in the RUN, HOLD, or END modes. The timer will go inactive when END is acknowledged or if the timer is disabled. The timer can be stopped by pressing the Enter and Right arrow keys during an active RUN state, sending a remote timer setpoint of 0 when the instrument is in remote mode, or by changing the remaining time to zero.
PAGE 36
VersaPro Temperature Controller Page 36 11.4 Guaranteed Soak Timer The guaranteed soak timer works in conjunction with the alarm process value. The alarm value is the valid band around the process setpoint. The process must be within the band around the process setpoint to start the timer once it has been activated. If the process passes above or below the alarm band setting, the timer will go to a HOLD state. The timer will be allowed to continue only when the process is within the band setting.

VersaPro Temperature Controller 13 Page 40 Tuning Before attempting to tune the instrument make sure you understand the Operation and Setup part of the instrument. This section applies to the controller only. 13.1 What is tuning? Tuning the controller means that the control characteristics of the controller are matched to those of the process in order to obtain hold the process to setpoint.
PAGE 41
VersaPro Temperature Controller Page 41 A much higher proportional band may be necessary for extreme lag in the process response. In most cases, the derivative part of the control equation is not necessary. Generally, furnace control can be maintained using only the proportional band and the reset parameters. Make sure you record all operating parameters and keep them in a secure place for later reference. Copyright © 2013, United Process Controls Inc.

VersaPro Temperature Controller 14 Page 43 Scaling Analog Inputs If either input is set to Linear mode the displayed value for that input can be scaled any desired engineering unit. This is helpful if the measured linear value has to be scaled and re-transmitted on one of two analog output channels. Using the equation y = mx + b, where Y is the desired engineering unit to be displayed X is the linear millivolt value M is the Slope of the y/x relationship B is the y intercept 14.
PAGE 44
VersaPro Temperature Controller 15 Page 44 Scaling Analog Outputs The analog outputs are scaled to simple offset and span values. For example if analog output 1 were to be scaled for a 0 to 2000° value, the offset value would be 0 and the span value would be 2000. It is possible to narrow the response to the process even if the instrument can measure a larger process range.
PAGE 45
VersaPro Temperature Controller 16.1 Page 45 Calibration Displays and Keyboard Operation When entering the Calibration Menu, the operator has to answer one of two questions depending on which I/O functions have to be calibrated. If the CALIBRATION IN prompt is answered with a YES, then the parameters related to the thermocouple input, millivolt input, and cold junction can be changed. If this prompt is skipped by pressing the Enter key, then a second prompt, CALIBRATION OUT is displayed.
PAGE 46
VersaPro Temperature Controller Page 46 Calibration of the Thermocouple Input Calibration procedure: 1. Connect terminals TB-B 1, 2 to an isolated, stable millivolt source calibrator using standard copper wire, 20 AWG is sufficient. 2. Set the calibrator output to 0.00 mV. 3. Activate the calibration mode by entering the SETUP menus, selecting the Calibration menu and changing Calibration IN - NO to YES. 4. Use the Enter key to select the TC ZERO mode. 5.

VersaPro Temperature Controller 17 Communications 17.1 Modbus Page 48 The MODBUS protocol describes an industrial communications and distributed control system (DCS) that integrates PLCs computers, terminals, and other monitoring, sensing, and control devices. MODBUS is a Master/Slave communications protocol, whereby one device, (the Master), controls all serial activity by selectively polling one or more slave devices.
PAGE 49
VersaPro Temperature Controller Page 49 The Function Code field tells the addressed slave what function to perform. MODBUS function codes are specifically designed for interacting with a PLC on the MODBUS industrial communications system. Command codes were established to manipulate PLC registers and coils. As far as the VersaPro is concerned, they are all just memory locations, but the response to each command is consistent with Modbus specifications.
PAGE 50
VersaPro Temperature Controller Page 50 The Versapro will respond to several error conditions. The three exception codes that will generate a response from the instrument are: 01 – Illegal Function 02 - Illegal Data Address 03 – Illegal Data Value 04 – Slave Device Failure The response from the Versapro with an exception code will have the most significant bit of the requested function set followed by the exception code and the high and low CRC bytes. 17.

VersaPro Temperature Controller 18 Page 57 Troubleshooting Questions This section is organized alphabetically by the functional name of various instrument operations and features. Some explanations may be listed in more than one category since the problem can be approached from several different points of view. Each problem is presented as a question for typical problems that may be encountered. In most cases the problem can be resolved by changing a setup parameter in the instrument. 18.
PAGE 58
VersaPro Temperature Controller 18.3 Page 58 Digital Communications How come I have communications problems with an instrument address following a Versapro address setting. If the timer function has been enabled and the Versapro host protocol is set to ‘Prop’ for the Marathon protocol, the instrument will take the next host address setting to respond with the timer parameters.
PAGE 59
VersaPro Temperature Controller 19 Page 59 Versapro Monitor Mode The Versapro’s internal EEPROM can be reprogrammed when placed in Monitor Mode. This mode allows the user to perform checks and set default conditions in the instrument by using a RS232 to RS485 converter and the popular Windows program HyperTerminal. It is necessary to enter this mode when a CPU has been reprogrammed or if a checksum fault has occurred in EEPROM.

PAGE 62
VersaPro Temperature Controller Page 62 The ‘K’ command is a single character command that copies the values in the RAM mirror into the EEPROM. The EEPROM is completely erased before any values are written. There is no display that is generated while this function is executed. It is necessary to wait about 5 seconds for the display prompt (>) to return before another command is issued. 19.
PAGE 63
VersaPro Temperature Controller Page 63 Figure 13 ‘S’ and ‘D’ Commands 19.12 Loading Default Values The most common use of the Monitor Mode is to re-set or load the processor’s internal EEPROM with default values and re-calculate the EEPROM checksum. This is done with a series of commands starting with the ‘L’ command. The instrument holds default operational parameters in FLASH. This area of memory is mapped the same way the EEPROM memory is.
PAGE 64
VersaPro Temperature Controller Page 64 Figure 14 ‘L’ and ‘K’ Commands At the prompt, type in the character ‘X’ and press Enter. The ‘X’ command causes the instrument to exit the Monitor Mode, reset, and return to operation mode. Check the instrument parameter settings and verify the input and output calibration settings. 19.13 What if an error occurs If you receive check sum errors following the ‘L’ or ‘K’ commands, retry these commands.
