LIQUID CRYSTAL DISPLAY (LCD)
The main information regarding the equipment is available on the LCD display. Figure 3.3 shows the LCD with all its
display fields. The numerical field is mainly used to indicate the values of the monitored variables. The alphanumeric
indicates the currently monitored variable, units, or auxiliary messages. The meanings of each of the icons are
described in table 3.2.

HART
®
PROGRAMMER
The configuration of the equipment can be carried out by means of a programmer compatible with HART
®
technology.
Vivace offers the VCI10-H interfaces (USB or Bluetooth HART
®
) as a solution for identification, configuration and
monitoring of HART
®
line devices.
Figures 3.4 and 3.5 illustrate the use of the USB VCI10-UH interface with a personal computer that has installed
HART
®
configurator software. In Figure 3.4, the interface is serially installed with the power supply of the equipment.
The interface requires a 250
Ω
resistor to enable HART
®
communication over the 4-20 mA current when powered
externally. In Figure 3.5, the interface is also used to power the transmitter, not requiring the communication resistor.
Figure 3.6 shows the assembly configuration of the transmitter called multidrop.
