Programmable Smart HART Temperature Transmitter
THZ
3
/ TDZ
3
SECTION 4
Section 4 - Configuration
The THZ
3
/ TDZ
3
can be configured using a HART communicator, HART host or a PC running
an FDT/DTM program. All functions can be configured using either method with the exception
of custom curves which cannot be generated or imported using the HART communicator.
However, once custom curves have been saved in the unit they can be selected using the HART
Communicator.
The following Configuration Overview is applicable to both programming methods. The
remainder of this Section details programming with a HART communicator. For details of
configuring using FDT/DTM please refer to Section 5.
Configuration Overview
The following will be an overview of configuration for the THZ
3
/ TDZ
3
.
Usage of the THZ
3
and TDZ
3
can be grouped into three general classifications:
•
Single Sensor
• Dual with “identical” sensors
•
Dual with diverse sensors.
When both sensors are being used, and they both produce the same units the measurements
can be combined to provide additional calculated values such as average, differential, low
select etc. The inputs can be either identical (e.g. the same exact RTD) or be different sensors,
producing the same measurement. For a full list of available measurements please see Tables
8.2 through 8.4 in Section 8.
Note:
To use a calculated Device Variable, both sensors’ engineering units (EGU) must be
compatible (i.e. the same, or both temperature units). If a calculated Device Variable has
different engineering units (EGU) from the sensors’ EGU, scaling will need to be used to
change the units.
Single Sensor
The THZ
3
or TDZ
3
can be configured to use a single sensor. Follow these steps:
1) Configure the sensor.
a. Use the “Configure Input Types” method to select
SEN
1, and to have
SEN
2 disabled.
b. Navigate to the Sensor 1 Configuration menu, and make any additional settings as needed.
2) Assign/Map the Device Variables to the HART Variables (PV, SV etc.) The only Device
Variables available are SEN1 and RJC T. In most cases, SEN1 should be assigned to PV
(Default setting).
3) Configure the PV Range (PV URV and LRV).
4) Configure the AO’s Range, limits, and fail response.
Note:
A single sensor 4W RTD is the factory default configuration. (see Quick start guide for
details)
