1 EQUIPMENT DESCRIPTION
VTT10-FH is the field model for Vivace’s temperature transmitter family, projected to be installed
directly on sensor or on a Ø 2” tube, panel or wall. It attends several sensor types, such as thermocouple,
RTDs, resistance and millivoltage signals.
The transmitter is powered by a 12 to 45 Vdc voltage and modulates communication over a 4-20 mA
output signal, according to NAMUR NE43 standard, using HART
®
protocol. The configuration uses HART®
7 (older versions compatible) communication protocol, already established on the world of industrial
automation for configuration, calibration, monitoring and diagnostics.
Through a HART configurator or any EDDL or FDT/DTM-based tool it is possible to configure sensor
type, measuring range, work unit, calibration and also monitoring measured variables with device status.
Configuration via local adjust is also possible with an auxiliary magnetic screwdriver.
Focusing on high performance and robustness, it was projected with the most recent electronic
component and material technology, offering long-term reliability for every scale systems.
1.1. BLOCK DIAGRAM
Component modularization for transmitter is described on the following block diagram.
Figure 1.1 – Transmitter block diagram.
The sensor signal passes through RF EMI filter and goes to ADC block, where it is converted to a
digital value. This digital value later will be converted in the temperature, according to selected sensor type.
The temperature value is finally converted in a current signal, proportional to the calibrated range.
The sensor signal is galvanic isolated from output signal, avoiding ground loop.

The input block (DC power supply) is responsible for the electric source for all circuits. Current control
block is composed by a circuit to transform digital values generated by microcontroller into 4-20 mA electric
current, proportional to the primary variable value.
HART
®
channel and HART
®
modem blocks provide the interface between microcontroller signals
and HART
®
bus connected to monitored device. Local adjust block enables local configurations by user.
The display board has the controller block to interface LCD and CPU communication signals,
adapting all the messages to be shown on display.
Finally, the CPU block can be seen as the transmitter brain, where all the activities happen, such as
time control, HART
®
machine, besides the common transmitter routines: configuration, calibration and
generation of output current, proportional to the primary variable.

.1. MECHANICAL ASSEMBLY
VTT10-FH was developed to be installed in the field, thus supporting exposition to several
environment situations, keeping good performance through any temperature, humidity and vibration
variations.
The transmitter’s housing is IP67 protected, being immune to water contact to electronic circuit and
electrical connections, since cable gland or conduit for electrical connection is correctly assembled and
sealed with non-hardening substance. Covers must also be tight to avoid humidity, since housing screws
are not protected by painting.
The electronic circuit is protected by varnish but constant water or corrosion exposure may
compromise this protection and damage the electronic components.
Figure 2.1 shows the dimensional drawing and mounting positions for VTT10-FH.
Figure 2.1 – Dimensional and mounting drawings for VTT10-FH.
To avoid the risk of involuntary loss of VTT10-FH covers due to vibration, for instance, it can be
locked by screw, as shown on figure 2.2.
VTT10-FH is a field device, so it can be installed through a mounting bracket on a 2” tube attached
with a U clip. For best LCD positioning device enables its display to be rotated 4 x 90°, according to figure
2.3. The transmitter can also be attached with the same mounting bracket to a wall or panel.

3 CONFIGURATION
The transmitter can be configured by any HART
®
compatible programmer. Vivace offers the
interfaces VCI10-H (USB, Android and Bluetooth) as a solution for configuring and monitoring any HART
®
device. VTT10-FH can also be configured by local adjust using Vivace magnetic screwdriver.
3.1. LOCAL CONFIGURATION
Transmitter’s local configuration is executed by using Vivace’s magnetic
screwdriver on Z and S orifices, located at housing superior side, under
identification plate. Orifice Z starts local configuration and changes the field to
be configured. Orifice S is responsible for changing and saving the new value
on the selected field. Saving after LCD value changing is automatic.
Figure 3.1 shows orifices Z and S for local configuration, stamped on device
housing, and their functions on magnetic screwdriver actuation.
Insert the magnetic screwdriver on Zero orifice (Z). icon appears to indicate
that device has recognized the screwdriver action. Keep the magnetic
screwdriver inside until “LOCAL ADJST” message is shown on display, then
remove it for 3 seconds. Insert the magnetic screwdriver into Z orifice again, so
user can navigate through local adjust parameters.
Table 3.1 indicates actions executed by magnetic screwdriver when inserted
on Z and S orifices.
Table 3.1 – Z and S orifices actions.
Figure 3.1 – Z and S orifices and
magnetic screwdriver.
Some parameters show the icon to allow user configuration on it by inserting the magnetic
screwdriver into Span orifice (S). In case the parameter has pre-defined values, those will be rotate on
display, while the magnetic screwdriver remains into Span orifice (S).
If the parameter is numerical, this field will enter on edition mode and decimal point will start blinking,
and shifting to left. When user removes magnetic screwdriver from S, the least significant digit (in the right)
starts blinking, indicating it is ready for edition. By inserting the magnetic screwdriver into S, user is enabled
to increase the digit value, from 0 to 9.
After the least significant digit edition, user should remove magnetic screwdriver from S in order to
start the edition of the next digit (in the left). User will be able to edit each digit independently, until the most
significant digit (5th digit on the left) is complete. After the 5th digit edition, user can also change the signal
for the numerical value still on S orifice.
During each step of edition, user is able to return to the previous digit (to the right) by inserting the
magnetic screwdriver into Z orifice, so corrections can be made. By removing the magnetic screwdriver at
any time, user will see the digits blinking until the final step, where the edition mode will be finished, saving
the numerical value configured by user.

If the configured value is not acceptable by that device parameter (invalid value), it will be returned
to the last valid value before edition. Depending on the parameter, some values can be shown on numerical
or alphanumerical fields, adjusting the best option view to user.
With the magnetic screwdriver out of Z and S orifices, device will leave local adjust mode after some
seconds and monitoring mode will be shown.
3.2.JUMPER CONFIGURATION FOR LOCAL ADJUST AND WRITE PROTECTION
VTT10-FH has two jumpers on its main board to protect data writing (WP1) and also
enabling/disabling local adjust (ADJL1). Figure 3.2 presents those jumpers.
Figure 3.2 – Jumpers WP1 (write protection) and ADJL1 (local adjust) on VTT10-FH main board.
Default selection for these jumpers is Write Protection DISABLED and Local Adjust ENABLED.

3.3.LIQUID CRYSTAL DISPLAY (LCD)
Main information related to transmitter are indicated on its liquid crystal display (LCD). Figure 3.3
shows the LCD with all its indication fields. Numerical field has 5 digits and is used mainly for monitored
variable indication. Alphanumerical field indicates which variable is being monitored, units or auxiliary
messages. Each indication icon use is described on table 3.2.

3.5. HART
®
CONFIGURATOR
Figure 3.5 exemplifies the use of USB interface with a personal computer that has a HART
®
configurator installed. A 250Ωresistance must be serially connected with the power supply (for voltage
supply and if the power supply does not have this resistance internally) in order to enable HART
®
communication over the 4-20 mA current (Figure 3.5). Vivace interface already has this resistance when
used to power the field device (Figure 3.6).
Figure 3.5 – Transmitter installation for configuration with external power supply and 250 ohms resistance.
Figure 3.6 – Transmitter installation for configuration using VCI10-UH to power the device.
VTT10-FH multidrop connection must be executed according to Figure 3.7. Note that up to 63 devices
can be paralleled connected on the same line. Caution must be taken when many transmitters are
connected on the same power line due to voltage drop on 250 ohm resistor and guarantee power supply
voltage is enough (Figure 3.8).

Information – Main device information can be accessed here.
•HART
®
– Main information about communication protocol are available here, such as:
Manufacturer, Device Type, Device Profile, HART
®
Revision, Software Version etc.
•Sensor – Main information about the sensor are available here, such as: Sensor
Type, Connection (2, 3 or 4 wires), Upper Range, Lower Range and Unit.
Configuration – Configuration of transmitter Work Ranges, Unit, Safe Mode and Damping are available
here.
•Damping is an electronic filter for PV variable which changes transmitter response time in
order to smooth output reading variations caused by input fast variations. Damping value can be configured
between 0 and 60 seconds, and its appropriated value must be adjusted based on process response time,
output signal stability and other system requirements. Default value for damping is 0 seconds.
The damping value affects transmitter response time. When this time is configured as zero, the
damping function is disabled and transmitter output will react immediately to the input variations, so the
response time will be as short as possible.
An increase to the damping value will result on an increase to transmitter response time.
As the settling time constant is defined, transmitter output will achieve 63% of the input variation and
transmitter will continue to approach the input value according to damping curve.
•Sensor – Sensor Type, Sensor Connection and Cold Junction Mode.
•Callendar van Dusen – R0, A, B and C parameters of Callendar van Dusen for RTDs.
