    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.

  • Page 38: Configuration Tt301 For Multidrop

    TT301 - Operation & Maintence Instruction Manual The TT301 is produced with the address equal to zero, in a point-to-point operational mode. The transmitter communicates with the configurator by overlaying the communication on the 4-20 mA signals. To operate in multidrop mode, the transmitter address must switch to a 1 to 15. This change deactivates the 4-20 mA analog output by assuming the fixed value equal to 4 mA (TRM mode), or maintains the 4-20 mA variable when the equipment is configured for PID mode.

  • Page 39: Section 4 - Programming Using Local Adjustment

    ADJUSTMENT The Magnetic Tool Smar's magnetic tool is the second man-machine interface; it compromises the advantage of the powerful Smar Configurator and the convenience of the "good-old" tool. If the transmitter is fitted with a display, and is configured for complete - local - adjustment (using internal jumper) the magnetic tool is almost as powerful as the Configurator, eliminating the need for a Configurator in most basic applications.
