THZ & TDZ
The HART Communicator Menu
Without a Device Description
This section contains the instructions for program-
ming a THZ or TDZ using a HART communicator
without a Device Description. If your communicator
has a Device Description, please see “The HART
Communicator Menu with a Device Description” on
page 15.
A. Displaying the Current Process
Values
The initial screen, the “Online Generic” menu,
displays the process value, analog output, and the
programmed upper and lower parameters of the
process value. The generic overview menu (Figure
12 on page 16) shows the screen. Use the DEVICE
SETUP menu for configuring your THZ or TDZ.
B. Configuring THZ or TDZ Input
The “Basic Setup” menu allows you to enter a name
for an individual transmitter, the units of measurement,
the upper and lower range and sensor values, and a
damping time between 0 and 30 seconds.
Damping smooths input fluctuations by taking an aver-
age over a user-programmed time period and using this
value for the output.
C. Configuring THZ Analog Output
The “Analog Output” menu displays the analog out-
put, changes the loop current to a fixed value so that
it can be checked against the value being received
and displayed by your receiving device, and enters
and trims the sensor.
D. Configuring HART Output
From the “HART Output” menu, you can enter the
polling address and display the number of preamble
characters sent by the master to the slave to ensure
synchronization.
If the polling address is set to 0, the THZ or TDZ is
automatically set to analog mode. Multiple units on
the same bus must have different addresses.
