TRZ
Programming the TRZ when a
Device Description is NOT
Available
This section contains the instructions for program-
ming a TRZ using a HART communicator without a
TRZ Device Description. If your communicator has
a Device Description for the TRZ, please see “Pro-
gramming the TRZ when a Device Description is
Available” on page 12.
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 main overview menu (Figure 7
on page 16) shows the screen. This menu will be
used throughout the process of programming a TRZ
without a HART device description.
Configuring TRZ Input
The “Basic Setup” menu allows you to enter a name
for an individual TRZ, the units of measurement, the
upper and lower range and sensor values, and a
damping time between 0 and 15 seconds.
Damping smooths input fluctuations by taking an aver-
age over a user-programmed time period and using
this value for the TRZ output.
To configure the TRZ input:
1.
Highlight DEVICE SETUP in the Online
Generic menu and push the right arrow.
2.
Highlight BASIC SETUP and push the right
arrow.
3.
Highlight TAG and push the right arrow to
display the current name of an individual
TRZ. Push EXIT to return to the Basic Setup
menu. To change or enter the TAG, skip to
step 6.
4.
Highlight PV UNIT and push the right arrow
to enter the measurement units. Scroll to the
correct units and push ENTER. The screen
returns to the Basic Setup menu.
5.
Highlight Range Values and push the right
arrow to enter the upper and lower range and
sensor values for the unit.
A.
Highlight PVLRV to enter the Lower Range
Value for the Process Variable. Input the
value and then push ENTER to return to the
Range Values Menu.
B.
Highlight URV to enter the Upper Range
Value for the Process Variable. Input the
value and then push ENTER to return to the
Range Values menu.
C.
Highlight PVLSL to enter the Lower Sensor
Level for the Process Variable. Input the
value and then push ENTER to return to the
Range Values menu.
D.
Highlight USL to enter the Upper Sensor
Level for the Process Variable. Input the
value and then push ENTER to return to the
Range Values menu.
E.
Scroll to PVLRV and use the left arrow to
return to the Basic Setup menu.
6.
Highlight DEVICE INFORMATION and push
the right arrow to enter the name and date for
the TRZ.
A.
Scroll past DISTRIBUTOR, MODEL, and
DEV ID. They cannot be changed.
B.
Highlight TAG and push the right arrow to
enter a name up to 8 characters long for the
TRZ. Input the name and push ENTER to
return to the Device Information menu.
C.
Highlight DATE and push the right arrow to
enter the date. Input the date and push
ENTER to return to the Device Information
menu.
D.
Scroll to DISTRIBUTOR and push the left
arrow to return to the Basic Setup menu.
7.
PV XFER FNCTN is not used. Highlight PV
DAMP and push the right arrow to enter a
damping time between 0 and 15 seconds for
the process value. After entering the value,
push ENTER to return to the Basic Setup
menu.
8.
Press HOME to return to the Online Generic
menu.
Configuring TRZ 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.
