    NOTE The installation carried out in hazardous areas should follow the recommendations of the IEC60079-14 standard. The FI302 is a high end device and thus, in order to take advantage to its maximum, the FI302 requires an appropriate installation. Many factors may affect the converter accuracy, among which environment conditions are the most difficult to control.

    Each preconfigured device must be installed on the specific plant site where it was configured for. Linking Device The linking device, for instance, the Smar DFI302 or other interface, addresses all the devices on each network automatically. For practical purpose, the node address may be hidden, once it is not of interest to most users, whose interaction is based on tags.

  • Page 21: Explosion/Flame Proof

    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.

    The transducer block also has a characterization curve, used to give a determined profile to the output. This is useful, for example, when the FI302 controls a valve with a non-linear feature. The characterization curve is applied to the input signal before being converted and sent to the analog output by the transducer.
