WARNING The SIS project must be carried through by a professional duly authorized from Smar and qualified for this type of work. WARNING Random, frequent or common cause failures must not damage the equipment´s work or result in death or serious injure, must not harm to the environment or equipment, and must not loss of equipment or production.

  • Page 12: Mounting

    ® TT400 HART SIS– Operation & Maintenance Instruction Manual Mounting The transmitter may be mounted in two basic ways, as follows: - Separated from the sensor, using optional mounting brackets; - Mounted on the sensor assembly. Using the brackets, the mounting may be done in several positions, as shown on Figure 1.1. One of the conduit inlets for electrical connection is used to mount the sensor integral to the temperature transmitter (see Figure 1.1).
  • Page 13 Installation Figure 1.2 – (a) Cover Locking with Display (b) Cover Locking of the Terminals The Figure 1.3 shows the correct installation of the conduit, in order to avoid entrance of water, or other substance, which may cause malfunctioning of the equipment.

  • Page 17: Section 2 - Operation

    Section 2 OPERATION ® The TT400 HART SIS accepts signals from mV generators such as thermocouples or resistive sensors such as RTDs. The criterium is that the signal is within the range of the input. For mV, the range is -50 to 500 mV and for resistance, 0 to 2000 Ohm.

  • Page 18: Temperature Sensors

    ® TT400 HART SIS – Operation and Maintenance Instruction Manual ® The TT400 HART SIS shows failure indication at 3.6 mA if configured for low signal failure or 21 mA if configured for high signal failure; 3.8 mA in the case of low saturation or 20.5 mA in the case of high saturation and measurements proportional to the applied temperature in the range between 3.8 and 20.5 mA.
  • Page 19 Operation For a correct measurement of RTD temperature, it is necessary to eliminate the effect of the resistance of the wires connecting the sensor to the measuring circuit. In some industrial applications, these wires may be hundreds of meters long. This is particularly important at locations where the ambient temperature changes a lot.

    ® TT400 HART SIS – Operation and Maintenance Instruction Manual Figure 2.4 – Four-Wire Connection A differential connection is similar to the two-wire connection and gives the same problem (see Figure 2.5). The resistance of the other two wires will be measured and does not cancel each other out in a temperature measurement, since linearization will affect them differently.

  • Page 25: Configuration Resources

    Configuration Configuration Resources ® ® Through the HART configurators, the TT400 HART SIS allows the following configuration resources to be accessed: Transmitter Identification and Manufacturer Data; Equipment Calibration; Equipment Configuration; Equipment Maintenance. The digital communication between the configurator and the transmitter do not interrupt the temperature measuring and do not disturb the output signal.

    4 mA output. If the signal is 100 percent, the output must be 20 mA. Differences may occur between the SMAR standard current and the plant standard. In this case, the current Trim adjustment should be used. The Configurator will adjust the output signal and then it will ask again if the current is correct or not.

  • Page 27: Burnout

    Configuration Burnout The burnout may occur when the sensor reading is out of range or the sensor is open. In this case, the transmitter may be adjusted for maximum output limit at 21.0 mA, by configuring it on the upper value, or the minimum limit at 3.6 mA configured on the lower value.
