  • Page 3 The IF302, like the rest of the 302 family, has several Function Blocks built in, like PID controller, Input Selector, Arithmetic, Signal Characterizer and Flow Totalization. These useful blocks eliminate the need for separate devices and reduce communication and therefore decreasing dead-time and making the control tighter, not to mention the reduction in cost.

    Section 1 INSTALLATION General NOTE The installation carried out in hazardous areas should follow the recommendations of the IEC60079-14 standard. The overall accuracy of measurement and control depends on several variables. Although the converter has an outstanding performance, proper installation is essential, in order to maximize its performance.
  • Page 10 Various types of Fieldbus devices may be connected on the same bus. The IF302 is powered via the bus. The limit for such devices is 16 for one bus (one segment) for non-intrinsically safe requirement. In hazardous area, the number of devices may be limited by intrinsically safe restrictions.

  • Page 13: Input Wiring

    Installation Input Wiring The IF302 accepts up to three current inputs in the range 0-20 mA or 4-20 mA. The three inputs have a common ground and they are protected from reverse polarity signal. The inputs should be connected as per Figure 1.6 - Input Wiring.
  • Page 14 In Explosion-Proof installations the cable entries must be connected or closed using metal cable gland and metal blanking plug, both with at least IP66 and Ex-d certification. The standard plugs provided by Smar are certified according to CEPEL certificate. If the plug needs to be replaced, a certified plug must be used.

  • Page 15: Functional Description - Electronics

    The IF302 accepts signals from mA generators such as most conventional transmitters. It is therefore ideal for interfacing existing equipment to a Fieldbus system. Functional Description – Electronics Refer to the block diagram (See Figure 2.1 - IF302 Block Diagram). The function of each block is described below. MUX Multiplexer The MUX multiplexes the input terminals to ensure that all three channels reach the A/D converter.

  • Page 17: Transducer Block

    One of the many advantages of Fieldbus is that device configuration is independent of the configurator. The IF302 may be configured by a third party terminal or operator console. The IF302 contains three input transducer blocks, one resource block, one display transducer block and function blocks.

    Current Trim The IF302 provides the capability of making a trim in the input channels, if necessary. A trim is necessary if the indicator reading of the transducer block output differs from the actual physical output. The reason may be: ...

Let’s take the lower value as an example: Supply 4 mA or the lower value to the terminal block and wait until the readout of parameter PRIMARY_VALUE stabilizes.

    LAST_TRIM_BACKUP. Via Local Adjustment The IF302 has 3 input transducers and its device leaves SMAR with factory settings. The factory setting establishes only the transducers #1 as default for local adjustment. In order to configure the others via local adjustment, the user should configure them in the display transducer via SYSCON, according specific instructions for this transducer block.
