The type of the electrical noise, source or coupling method into the unit may be different for various installations. In extremely high EMI environments, additional measures may be needed. The unit 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 a troublesome installation. Listed below are some EMC guidelines for successful installation in an industrial environment. 1. The unit should be mounted in a metal enclosure, that 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 to earth ground (protective earth) only at the panel 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 above 1 MHz. c. Connect the shield to common of the unit 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 away 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 # FN610-1/07 (RLC #LFIL0000) Schaffner # FN670-1.8/07 Corcom #1VR3 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.

Refer to EMC Installation Guidelines section of the bulletin for additional information. 2 WIRING CONNECTIONS PROGRAMMING All conductors should meet voltage and current ratings of the unit. Also, cabling should conform to appropriate standards of good installation, local codes and regulations. It is recommended that power supplied to the unit be protected by a fuse or circuit breaker. Unit should be mounted in a relatively stable temperature environment. Avoid drafts and areas subject to radical temperature shifts. Programming may be entered at any time during normal operation Entering the Program Menu of the CUB4TC is accomplished by electrically connecting the PROGRAM terminal to the COMM terminal with a wire or closed switch. Programming may be exited at any time except during calibration. Exiting the Program Menu of the CUB4TC is accomplished by breaking the electrical connection between the PROGRAM terminal and the COMM terminal. During exit of programming, the unit displays SAVE to indicate that the data is currently being written to non-volatile memory. All programming data is stored upon exit of programming. If power is removed from the CUB4TC during exit of the Program Menu, data may not be saved completely or correctly, and may cause a FAIL message to occur during the next power-up cycle. If power is removed from the CUB4TC before exiting the Program Menu, all changes (including calibration information) will be lost and previous values will be used upon power-up. Programming the CUB4TC involves using the “SEL” and “blank” buttons to traverse the Programming Menu and to select values for the corresponding Programming Menu Items. CAUTION: To maintain the SELV rating of the CUB4TC, the thermocouple probe should be isolated from any accidental contact with hazardous voltage or non-SELV circuitry. SEL: Steps to next Program Menu selection Blank: Scrolls through selection variables and enters into programming for the selected value. PROGRAM MENU - Selection Variables Electrical Connect thermocouple wires to terminals TC+(#3) and TC-(#5), observing the correct polarity. Keep wire length to a minimum to reduce lead resistance errors. Do not run thermocouple wires with Class 1 wiring. Connect the 9 to 26 VDC power to terminals V+(#2) and COMM.(#1), observing the correct polarity. Note: Do not connect the power supply COMM terminal (#1) to the TCterminal (#5), as erroneous readings will result. If more than one CUB4TC are powered from the same supply, the probes must be isolated from each other. Also be aware when using grounded thermocouple probes that the probes’ protective sheath is electrically connected to the measuring junction. If the protective sheath is connected to the power supply common, this will connect terminals 1 and 5 together, which may result in erroneous readings. tYPE - t, E, J, k, r, S, b, n or LIN To select the input type, press the blank button to scroll through the available input types. Press the “SEL” button to enter the choice and return to the main menu. CJC - YES, NO This program item enables or disables internal cold junction compensation. Pressing the “blank” button toggles between Yes and No. For most applications, cold junction compensation should be enabled (yES). Press the “SEL” button to enter the choice and return to the main menu. This menu item does not appear if tYPE = LIN. dISP - 0C , 0. 0 C , 0F , 0. 0 F BASIC OPERATION This program item sets the display for Fahrenheit or Celsius and whole number or tenths. Tenths is not available for thermocouple types R, S, and B. To change the display, use the “blank” button to scroll through the list of choices. Press the “SEL” button to enter the choice and return to the main menu. This menu item does not appear if tYPE = LIN. Normal operation begins with application of power to the CUB4TC. The unit will begin a power up sequence that displays the version of the software and any diagnostic messages. After approximately four seconds, the unit will begin to display the temperature of the thermocouple probe or the millivolt input, depending upon input type selected. A diagnostic message of FAIL may occur on power up. This message indicates that the stored programming and/or calibration values may have become corrupted. Pressing the “SEL” button will remove the current message from the display. Once the unit is displaying temperature or millivolts, the “SEL” button may be pressed to display the type of input the unit has been programmed to display. The display will show J, K, E, T, R, S, B, N, or Lin. The display will return to normal indication after three seconds. FLtEr - 0, 1, 2, 3 If the displayed process signal is difficult to read due to small process variations or noise, increased levels of filtering will help to stabilize the display. Software filtering effectively combines a fraction of the current input reading with a fraction of the previous displayed reading to generate the new display. Filter values represent no filtering (0), up to heavy filtering (3). A value of 1 for the filter uses 1/4 of the new input and 3/4 of the previous display to generate the new display. A filter value of 2 uses 1/8 new and 7/8 previous. A filter value of 3 uses 1/16 new and 15/16 previous. To select the filter level, use the “blank” button to scroll through the list of choices. Press the “SEL” button to enter the choice and return to the main menu. DIAGNOSTIC MESSAGES FAIL - indicates that a non-volatile memory fault has occurred. The operator must acknowledge this message by pressing the “SEL” button before proceeding to normal operation. Once the unit is in normal operation, the messages FLPrG and or FLCAL will be periodically flashed on the display. rANGE - 00000 to 00099 The Range value selected determines if the filter, as set previously, will be applied to the new input sample. If the new input value is within the ± range of the previous display, the filter will be applied to the new input. FLPrG - indicates that non-calibration data is corrupt. This flashing display will remain active even if power is removed and reapplied, until the unit is reprogrammed. If the message appears on next power up after the unit has been reprogrammed, it may indicate a nonfunctional memory component. Example: new input sample = 891 °C previous display = 885 °C range = 10 °C FLCAL - indicates that calibration data is corrupt and nominal values will be used to calculate the display value. This flashing display will remain active even if power is removed and reapplied, until the unit is recalibrated. If the message appears on next power up after the unit has been recalibrated, it may indicate a nonfunctional memory component. The nominal values used to calculate the input signal value may cause indication errors of up to 10% of full scale. The unit should be recalibrated to restore normal display accuracy as soon as possible. 885 ± 10 = 875 to 895 degree filter range based on previous display. The new input sample (891 °C) is within ± 10 °C of the previous display (885°C), so the filter is applied to the new input signal. If the new input is outside the filter range, no filter is used. This allows fast response to large signal changes and maximum filtering of small signal changes. To enter the range value, use the “blank” button to increment the flashing digit. To select a new digit, press the “SEL” button. After the desired value is on the display, press and hold the “SEL” button for three seconds to enter the value and return to the main menu. 3 OFSEt - ± 00000 to 99999 CAL - YES/NO The offset value is used to add or subtract a constant temperature from the display. Typically this value should be zero. Changing this value does not affect calibration, but will affect the displayed temperature. If a constant offset error is occurring in the application, this feature may be used to reduce or eliminate that error. To enter an offset value, use the “blank” button to increment the flashing digit or the sign of the number. To select a new digit or sign of the number, press the “SEL” button. If no digits are flashing, use the “blank” button to toggle the sign of the number or press the “SEL” button to wrap around to the LSD. After the desired value is on the display, press and hold the “SEL” button for three seconds to enter the value and return to the main menu. Read the entire Calibration instructions before attempting to calibrate the unit. Access codes are contained in the calibration procedures. This unit is calibrated from the factory. Initial calibration is not necessary. Calibration should only be performed by individuals experienced in calibrating electronic equipment. This item places the unit in calibration mode. Read the entire Calibration section before attempting to calibrate this unit. If calibration is entered by accident, press and hold the “SEL” button when the display shows 00000 for access code. Approximately three seconds later the display will return to tYPE in the Program Menu. To enter the Calibration Mode, use the “blank” button to change the NO to a YES. Press the “SEL” button to enter the choice. CALIBRATION VOLTAGE CALIBRATION The CUB4TC uses stored voltage calibration and cold junction temperature values to provide accurate temperature and voltage measurements. Over time, the electrical characteristics of the components inside the CUB4TC will slowly change with the result that the stored calibration values no longer accurately define the input circuit. For most applications, recalibration once every 1 to 2 years should be sufficient. Calibration of the CUB4TC involves a voltage calibration and a cold junction calibration. It is recommended that both calibrations be performed. The voltage calibration MUST precede the cold junction calibration. Allow 30 minute warm-up before performing any calibration related procedure. The following procedures should be performed at an ambient temperature of 15 to 35 °C (59 to 95 °F). Calibration should only be performed by individuals experienced in calibrating electronic equipment. CAUTION: The accuracy of the calibration equipment will directly affect the accuracy of the CUB4TC. Voltage Calibration Wiring 1. Connect a precision Voltage Source with an output range of -10.000 to 60.000 mV and an accuracy of 0.03% or better to the TC- (#5) and TC+ (#3) terminals. Cold junction calibration must be performed AFTER voltage calibration. 2. Enter the Program Menu and step through the Program Menu list by pressing the “SEL” button until CAL is displayed. 3. Press the “blank” button to change no to YES. Press “SEL”. 4. The display shows 00000. Use the “blank” button to increment the access code to 00006. Press and hold “SEL”. 5. After entering the correct access code, the unit will display IN1. Follow the table below for calibration sequence.The unit displays CALC for about 3 seconds after pressing the “SEL” button before proceeding to the next input point. Voltage Calibration Check 1. Enter the programming menu and set tYPE to LIN and OFSEt to 0. Exit programming. 2. Use a precision DC voltage supply with an accuracy of 0.03% or better. Connect the negative lead of the power supply to TC- (#5) and the positive lead of the power supply to TC+ (#3). 3. Compare the CUB4TC read-out to the precision DC supply at various points over the range (–10.00 mVDC to 60.00 mVDC). The tolerance is ± 2 LSD (±0.02 mV), at all points within this range. 4. Calibrate the CUB4TC if the readings are out of tolerance. Cold Junction Calibration Check 1. Enter Programming Menu, and verify the following: tyPE = probe being connected to the unit. CJC = YES dISP = 0.0°C OFSEt = 0 Make any necessary changes to programming. 2. Connect a thermocouple probe of known accuracy and type (J, K, E, T, or N) to the CUB4TC. The probe should match the one selected in programming. 3. Connect a reference temperature probe to measuring end of thermocouple to monitor temperature. Allow sufficient time for temperatures to equalize (at least 15 minutes). 4. Compare unit display with reference temperature indicator. The unit display should equal the reference probe temperature. Tolerance is ±1.0 °C. 5. Calibrate the cold junction temperature if out of tolerance. DISPLAY PARAMETER ACTION IN1 IN2 IN3 IN4 IN5 IN6 IN7 IN8 -10.000 mV Apply -10.000 mV, wait 5 sec., press SEL 0.000 mV Apply 0.000 mV, wait 5 sec., press SEL 10.000 mV Apply 10.000 mV, wait 5 sec., press SEL 20.000 mV Apply 20.000 mV, wait 5 sec., press SEL 30.000 mV Apply 30.000 mV, wait 5 sec., press SEL 40.000 mV Apply 40.000 mV, wait 5 sec., press SEL 50.000 mV Apply 50.000 mV, wait 5 sec., press SEL 60.000 mV Apply 60.000 mV, wait 5 sec., press SEL 6. After voltage calibration is complete, the unit will return to the CAL program item. Exit programming and verify various points from -10.00 to 60.00 mVDC using the Voltage Calibration Check procedure to ensure that the calibration is correct. 7. Repeat calibration if necessary. 4 2. Connect a thermocouple probe of known accuracy and type (J, K, E, T, or N) to the CUB4TC. The probe should match the one selected in programming. 3. Connect a reference temperature probe to measuring end of the CUB4TC thermocouple.The two probes should be shielded from air movement and allowed sufficient time (15 minutes minimum) to equalize in temperature. (As an alternative, the CUB4TC thermocouple probe may be placed in a calibration bath of known temperature.) 4. Compare the unit display with reference temperature indicator (or calibration bath). If the displayed unit temperature does not equal the reference probe temperature, calculate the CJ error as follows: CJ Error = reference probe temperature - CUB4TC displayed temperature 5. Enter the Program Menu and step through the Program Menu list by pressing the “SEL” button until CAL is displayed. 6. Press the “blank” button to change no to YES. Press “SEL”. 7. The display shows 00000. Use the “blank” button to increment the access code to 00003. Press and hold “SEL”. 8. After entering the correct access code, the display will alternate between CJC and the current cold junction compensation value. 9. If the current CJC value is 0.0 °C or 59.9 °C, set the CJC value to the current ambient temperature, exit calibration, and repeat the CJC calibration procedure. 10. Otherwise, the new value to be entered is the sum of the current value and the CJ Error recorded previously. 11. Exit the Programming Menu and repeat the calibration from Step 4 to verify accuracy. COLD JUNCTION CALIBRATION This procedure must be performed AFTER an accurate voltage calibration. The ambient temperature at which this calibration should be performed is 15 to 35 °C (59 to 95 °F). A Temperature indicator with 0.1 °C resolution and accuracy is required to perform this calibration. 1. Enter Programming Menu, and verify the following: tyPE = probe being connected to the unit. CJC = YES dISP = 0.0°C OFSEt = 0 Make any necessary changes to programming. Cold Junction Calibration Wiring INSTALLATION The CUB4TC meets NEMA 4X/IP65 requirements for indoor use, when properly installed. The units are intended to be mounted on an enclosed panel. The viewing window and buttons are factory sealed for a wash down environment. A sponge rubber gasket and mounting clip are provided for sealing the unit in the panel cut-out. Installation Environment The unit should be installed in a location that does not exceed the maximum operating temperature and provides good air circulation. Placing the unit near devices that generate excessive heat should be avoided. The bezel should be cleaned only 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 buttons of this unit. The following procedure assures proper installation: 1. Cut the panel opening to the specified dimensions. Remove burrs and clean around the panel opening. 2. Carefully slide the panel gasket over the rear of the unit to the back of the bezel. 3. Assemble the nut fastener and mounting screw onto both sides of the mounting clip. The tip of the screw should not project from the hole in the mounting clip. 4. Install the unit through the panel cut-out until the front bezel flange contacts the panel. 5. Slide the mounting clip over the rear of the unit until the mounting clip is against the back of the panel. The mounting clip has latching features which engage into mating features on the housing. 6. Alternately tighten each screw to ensure uniform gasket pressure. Visually inspect the front panel gasket. The gasket should be compressed to about 75 to 80% of its original thickness. (Recommended torque is 28 to 36 in-oz.) If not, gradually turn the mounting screws to further compress the gasket. 7. If the gasket is not adequately compressed, and the mounting screws can no longer be turned, loosen the mounting screws and check that the mounting clip is latched as close as possible to the panel. Repeat the procedure for tightening the mounting screws.
