Functional Safety Dual Input Smart HART® Temperature Transmitter
STZ
SECTION 4
Section 4 - Configuration
The STZ 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 STZ.
Usage of the STZ
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 (in SEN1 and SEN2)
they can be combined in the derived variables. The inputs can be either identical (e.g. the same
exact RTD) or be different sensors, producing the same measurement.
If both sensors are being used and they produce different units, then the derived variables cannot
be used.
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 STZ 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) Specify Variable mapping - The only variables which can be mapped as Dynamic
Variables are: RJC T, and SEN1. In most cases, SEN1 should be used as the PV.
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)
