- - INSTALLATION The TxRail transmitter is intended for DIN rail mounting. Its drawing is presented in figure 4. 19 mm 69 mm 72 mm 77 mm 78 mm 72 mm 77 mm Figure 4 – TxRail dimensions ELECTRICAL CONNECTIONS Connector specification: ♦ Insulating material: Polyamide, self-extinguishing to UL 94, V-0 ♦ Connection wire cross section: 0,14 - 4.0 mm² ♦ Screw tightening torque: 0,8 Nm / 7.0 lb-in ♦ Terminal block: CuZn It is important to follow the recommendations below: ♦ Signal wires should be installed in grounded conduits and away from power or contactor wires. ♦ The instrument should have its own power supply wires, which should not be shared with electrical motors, coils, contactors, etc. ♦ Installing RC filters is strongly recommended at contactor coils or any other inductors. ♦ System failure should always be taken into account when designing a control panel to avoid irreversible damage to equipment or people. Figure 5 below shows the TxRail connections to the sensor and power supply. Terminals 1, 2 and 3 are used for sensor input. For 2-wire Pt100, terminals 2 and 3 shall be connected together.

TRANSMITTER 1 6 2 5 3 4 10 11 12 LOAD POWER SUPPLY TERMOCOUPLE SENSOR Figure 6 – TxRail wiring (Thermocouple) OPERATION All input types and the 0-10 Vdc output are factory calibrated. However, a manual offset trim is implemented to provide fine adjustments to the signal in the field. This is accomplished by the front keys ZERO+ and ZERO-. Using a small tool, press and hold the desired key for at least 2 seconds to increase or decrease the output. The offset adjustment is capable of varying the output current by an amount equal to ± 5 % relative to the original calibration.. The offset correction can also be accomplished by the TxConfig software. See in Figure 3 the Zero Correction field for this purpose. The serial adaptor can be connected to the transmitter while it is operating in the process. Note: when using a Pt100 simulator, make sure the TxRail Pt100 excitation current (0.18 mA) is compatible with the simulator specification. The input types are listed in Table 1, along with the maximum and minimum ranges accepted by each one. The TxConfig software will allow only configurations that are consistent with the data in this table. Please note that the specified accuracy is referenced to the maximum span of each input type. For instance, for the Pt100 input, the 0.2 % accuracy results in 1.7 ºC total accuracy [(650 – (-200)) x 0.2].

OPERATION All input types and the 4-20 mA output current are factory calibrated. However, a manual offset trim is implemented to provide fine adjustments to the signal in the field. This is accomplished by the front keys ZERO+ and ZERO-. Using a small tool, press and hold the desired key for at least 2 seconds to increase or decrease the output current. The offset adjustment is capable of varying the output current by an amount equal to ±0.80 mA relative to the original calibration.. The offset correction can also be accomplished by the TxConfig software. See in Figure 3 the Zero Correction field for this purpose. The serial adaptor can be connected to the transmitter while it is operating in the process.

NOVUS AUTOMATION 1/3 TxRail 4-20 mA Transmitter TEMPERATURE TRANSMITTER - OPERATING MANUAL – V1.2x F CONFIGURAÇÃO If the default configuration or the ordered configuration satisfies the application, then no further configuration is necessary and the transmitter is ready to be used. If a new setting is desired, this can be accomplished by the TxConfig and sent to the transmitter through the TxConfig Interface. The TxConfig Interface and Software compose the Transmitter Configuration Kit, which can be purchased separately. The latest release of this software can be downloaded from our web site. To install, run the Tx_setup.exe and follow the instructions. Serial port configuration errors may occur when other software are sharing the same serial port. Close all serial port applications prior to using the TxConfig software. The TxConfig interface connects the transmitter to the PC, as shown in Fig. 1 and 2. There are two types of interface: TxConfig-RS232 and TxConfig-USB. Fig. 1 – TxConfig Interface connections model RS232 Fig. 2 – TxConfig Interface USB connections Once the connection is accomplished, the software shows the configuration options of the transmitter model attached. Access the Help for usage instructions. Fig. 3 shows the TxConfig software main screen. Fig. 3 – TxConfig main screen The fields in the screen mean: 1. Input Sensor: Choose the desired temperature sensor among the available options. See Table 1. 2. Measuring Range: Defines the output scale for the input sensor. Program here the measurement Lower Range Value and the Upper Range Value. When the Low Scale Limit is configured with a value higher than the Full Scale Limit, the current output will have a decrescent behavior (20~4 mA). The values configured in these fields can not be beyond the sensor measuring range. The minimum span value has to be observed as well. See Table 1. 3. Line Noise Rejection: The transmitter incorporates a digital filter to cancel the induced noise from the 50 or 60 Hz systems. For better performance, select the line frequency used in your country. 4. Sensor Failure Detection: establishes the transmitter output behavior (upscale or down-scale) in the presence of a sensor fail. 5. Zero Correction: Allows for small sensor corrections. See item Operating. 6. Device Information: The Device Information box contains relevant data concerning a particular transmitter. Please pass along this information when contacting the technical assistance department. 7. Read Device: Brings to the screen the current transmitter parameters configuration. 8. Apply: Sends a new configuration to the transmitter. Note: The factory default configuration is (unless otherwise specified or ordered):  Pt100 input, 0 to 100 °C.  60 Hz filtering and up scale (20 mA) output for sensor fail.
