Preparations for Wiring 2.5 2.5.1 WIRING GUIDELINES Electrical noise is a phenomenon typical of industrial environments. The following are guidelines that must be followed to minimize the effect of noise upon any instrumentation. 2.5.1.
contact with each other and amount of cross talk. Cross talk is due to the EMF (Electro Magnetic Flux) emitted by a wire as current passes through it. 2.5.1.4 USE OF SHIELDED CABLE Shielded cable helps eliminate electrical noise being induced on the wires. All analog signals should be run with shielded cable. Connection lead length should be kept as short as possible, keeping the wires protected by the shielding. The shield should be grounded at one end only.
2.5.2 SENSOR PLACEMENT (THERMOCOUPLE OR RTD) If the temperature probe is to be subjected to corrosive or abrasive conditions, it should be protected by the appropriate thermowell. The probe should be positioned to reflect true process temperature: In liquid media - the mose agitated area. In air - the best circulated area. THERMOCOUPLE LEAD RESISTANCE Thermocouple lead length can affect instrument accuracy, since the size (gauge) and the length of the wire affect lead resistance.
RTD LEAD RESISTANCE RTD lead length can affect instrument accuracy. Size (gauge) and length of the wire used affects lead length resistance. To determine the temperature error resulting from the lead length resistance, use the following equation: Terr = TLe * L where; TABLE 3 3 Wire RTD AWG No. 10 12 14 16 18 20 24 TABLE 4 AWG No. 10 12 14 16 18 20 24 TLe = value from Table 3 if 3 wire or Table 4 is 2 wire. L = length of leadwire in thousands of feet. Error °C +/-0.04 +/-0.07 +/-0.10 +/-0.16 +/-0.
Wiring Connections 2.6 All wiring connections are typically made to the instrument at the time of installation. Connections are made at the terminal boards provided, two 12 gauge wires maximum. Terminal boards are designated TB1 through TB13. See Figure 2-4 for the terminal board locations. The number of terminal boards present on the instrument depend upon the model number/ hardware configuration.
FIGURE 2-5 AC Instrument Power Input Connect the 115 VAC hot and neutral to terminals 1 and 2 respectively of TB1. See Figure 2-4 (page 14) for Terminal Board locations on the instrument. Connect the 230 VAC one leg to each terminal, be sure to check the position of the Voltage Selector switch provided with 230 VAC instruments. The switch position must match the voltage input to the instrument.
FIGURE 2-8 Volt, Millivolt and milliamp Input Make the volt, millivolt and milliamp connections as shown below. Use TB4 for thePen 1 input, and TB5 for the Pen 2 input. Terminal 1 is positive and terminal 2 is negative. The milliamp input requires the installation of an appropriate shunt resistor (ordered separately) between terminals 1 and 2. Be sure that input conditioning jumpers are in the correct positions for the input being connected. See Appendix A-1 (page 62).
FIGURE 2-10 Digital Communications Options Connections are made as shown using TB2. Refer to the Protocol Manual, Form #2878 for more details regarding the connections and how to use this option. This document is provided only when this option has been specified. If the communications network continues on to other instruments, connect the cable shields together, but not to the instrument. A terminating resistor should be installed at the terminals of the last unit in the communications loop.
FIGURE 2-12 SSR Driver Output Connections are made to relays D through A as shown. Terminal connections are made using TB7 and TB6, depending on the number of SSR Driver outputs specified. + 1 2 3 4 - SSR TB6 OR TB7 FIGURE 2-13 Current Output Connections are made to current outputs A and B as shown. Each current output is programmable as either 4 to 20 mADC or 0 to 20 mADC. Each output must be assigned to the desired function in the Program mode.
FIGURE 2-14 Transmitter Power Supply Input If the isolated 24 VDC regulated transmitter power supply has been specified, the connections should be made as shown. Connections are made using TB3, terminal 1 is positive and terminal 2 is negative. The power supply is capable of providing the power needed by up to 2 transducers (40 mADC maximum).
Configuration 3.1 After completing installation and wiring of the instrument the configuration (set up) procedures must be performed to prepare the instrument for operation on the intended application. The procedures include selecting specific parameters, entering data and possible jumper positioning. Once properly configured the instrument will retain the user selections in memory so this procedure need not be repeated unless required by changes in the application.
