Phone: 219/879-8000 Fax: 219/872-9057 www.dwyer-inst.com e-mail: info@dwyermail.comINSTALLATION 1. Location: Select a location where the temperature of the transmitter will be between -4 and 158°F. Distance from the receiver is limited only by total loop resistance. 2. Position: The transmitter is not position sensitive. Units with the optional display should be mounted for ease of viewing the display. 3. Electrical Connection: Wire Length - The maximum length of wire connecting the transmitter and receiver is a function of wire size and receiver resistance. Wiring should not contribute more than 10% of the receiver resistance to total loop resistance. For extremely long runs (over 1000 feet), choose receivers with lower resistance to minimize the size and cost of connecting leads. Current (4-20 mA) Output Operation An external power supply is required. See Figure A for diagram of the connection of the power supply, transmitter and receiver. The range of appropriate receiver load resistance (RL) for the DC power supply voltage available is expressed by the formula: R L = V ps – 10 20 mADC Shielded cable is recommended for control loop wiring. FM Explosion-Proof Installation Notes: 1. Install in accordance with any applicable national electric code. 2. Plug unused conduit openings. Plug must engage a minimum of 5 threads. 3. Use a conduit seal within 18 inches of conduit entry. 4. Disconnect power before servicing. Electrical connections to the RTD Transmitter are made to the terminal block located inside the housing. Unscrew and remove the cover. Wire as shown in Figure B. Temperature Range Selection The RTD Transmitter has 7 built in temperature ranges and a user settable range that are selectable by setting the Dip Switch located inside the housing (Figure C). Switches 2, 3, and 4 are used to set the range. To set the desired range, unscrew and remove the cover and set the Dip Switch according to the following table: - RECEIVER + mA 1 2 3 4 5 6 POWER SUPPLY 10-35 VDC RTD TRANSMITTER + - Figure A RTD SENSOR LEADS CURRENT LOOP + - Figure B Figure C Selectable Ranges Dip Switch 234 40 to 90°F (4.4 to 32.2°C) -20 to 140°F (-28.9 to 60°C) 0 to 100°F (-17.8 to 37.8°C) 30 to 240°F (-1.1 to 115.6°C) 32 to 212°F (0 to 100°C) 32 to 122°F (0 to 50°C) -30 to 65°C (-1.1 to 18.3°C) User ettable OFF ON OFF ON OFF ON OFF ON OFF OFF ON ON OFF OFF ON ON OFF OFF OFF OFF ON ON ON ON CAUTIONSetting and Calibrating the User Settable Range By setting SWITCH 2, 3, and 4 on, the RTD Transmitter may be adjusted to a custom user specified range. The range may be any values between –30°F and +250°F (-34 to +121°C) with a MINIMUM SPAN of 40°F (22°C). Equipment Required In order to calibrate the unit for a custom range, a precision RTD simulator that can simulate a 1000 OHM DIN type RTD or precision decade box is required. The device must be capable of generating the correct RTD resistance to 0.1% or better. Calibration Procedure 1. Set DIP SWITCHES 2, 3 and 4 ON. 2. Remove the RTD sensor leads from terminals 5 and 6 (Figure B). Connect the precision RTD simulator or decade box to terminals 5 and 6. 3. Wire instrument as previously discussed. A current meter may be wired in series with the unit to verify the correct current output, but this is not necessary for calibration. Apply power to the unit. 4. If a precision RTD simulator is used, make sure it is set to simulate a 1000 OHM DIN 0.00385 RTD. Then set it to the desired minimum temperature. If a decade box is used refer to the table in Appendix A (°F) or Appendix B (°C) and set it to the resistance that represents the desired minimum temperature. 5. Press the ZERO button. If the unit has the optional LCD, the display will read ZERO OK momentarily. If a current meter is wired, it will read 4.00 mA. 6. Repeat step 4 using the value for the maximum desired temperature. 7. Press the SPAN button. If the unit has the optional LCD, the display will read SPAN OK momentarily. If a current meter is wired, it will read 20.00 mA. 8. Turn off power to the unit. Disconnect the RTD simulator or decade box and reconnect the RTD sensor to terminals 5 and 6. Calibration is complete. Note: The calibration procedure does not effect the calibration of any of the built in ranges. °F and °C Selection If the unit has the optional LCD display, DIP SWITCH 1 sets the display to read in °F or °C. SWITCH 1 “OFF” = °F SWITCH 1 “ON” = °C. Output Current Display If the unit has the optional LCD display, the lower display will show the output current if DIP SWITCH 5 is “ON”. Setting DIP SWITCH 5 “OFF” causes the lower display to be blank. Open RTD Protection Upon detecting an open RTD, the unit may be set to force the output to read 3.5 mA or 21mA based upon the setting of DIP SWITCH 6. SWITCH 6 “OFF”, output forced to 3.5 mA SWITCH 6 “ON”, output forced to 21 mA Calibration The unit requires no calibration. An internal precision resistor continually self calibrates the unit. Calibration may be verified by removing the sensor leads and testing the unit against a precision RTD simulator or a precision decade box. If the unit is found to be out of calibration it must be returned to the factory for service. ELECTRICAL CONNECTIONS Connect wire leads in accordance with local electrical codes. For units supplied with both internal ground and external bonding terminals, the ground screw inside the housing must be used to ground the control. The external bonding screw is for supplementary bonding when allowed or required by local code. When external bonding conductor is required, conductor must be wrapped a minimum of 180° about the external bonding screw. See below. EU-Type Certificate, IECEx Installation Instructions: Cable Connection The cable entry device shall be certified in type of explosion protection flameproof enclosure “db”, suitable for conditions of use and correctly installed. For ta ≥ 70°C cable and cable gland rated ≥ 75°C (MIN.) shall be used. Conduit Connection An Ex db certified sealing device such as a conduit seal with setting compound shall be provided immediately to the electrical entrance of the transmitter housing. For ta ≥ 70°C wiring and setting compound, in the conduit seal, rated ≥ 75°C shall be used. Unused entries shall be sealed with an Ex certified blanking device rated for the appropriate zone, equipment group and temperature classification and shall be installed per manufacturer instructions. Note: For ATEX/IECEx units only: When employed in a Zone 1, EPL Gb (db) application, the temperature class is determined by the maximum ambient and or process temperature. Units are intended to be used in ambient of -20°C≤ Tamb ≤70°C. Units may be used in process temperatures up to 120°C providing the enclosure temperature do not exceed 70°C. The standard Temperature Class is T6 Process Temp ≤80°C. Remaining temperature classes are, Temperature Class of T5 Process Temp ≤95°C and Temperature Class T4 Process Temp ≤ 120°C. Refer to Certificate No: Element IECEx EMT17.0007X for conditions of safe use for IECEx compliant units. All wiring, conduit and enclosures must meet applicable codes for hazardous areas. Conduits and enclosures must be properly sealed. For outdoor or other locations where temperatures vary widely, precautions should be taken to prevent condensation inside enclosure. Electrical components must be kept dry at all times. When employed in a Zone 20, EPL Da (ta) application, the equipment is to be used with a power source rated for a prospective short circuit current of 10 kA. If the power source is rated for a prospective short circuit current of less than 10 kA, the end user or installer must mark the equipment with the prospective short circuit current rating of the power supply it is used in conjunction with. MAINTENANCE Inspect and clean wetted parts at regular intervals. The cover should be in place at all times to protect, the internal components from dirt, dust and weather and to maintain hazardous location ratings. Disconnect device from the supply circuit before opening to prevent ignition of hazardous atmosphere. Repairs to be conducted by Dwyer Instruments, Inc (field repair should not be attempted and may void warranty). Units in need of repair should be returned to the factory prepaid. Be sure to include a brief description of the problem plus any relevant application notes. Contact customer service to receive a return goods authorization number for shipping.
