THZ
3
/ TDZ
3
SECTION 4
Dual with Identical Sensors
The THZ
3
or TDZ
3
can be configured for use with two identical sensors. Follow these steps:
1) Configure the sensor
a. Use the “Configure Input Types” method to select SEN1, and to use the same sensor for
SEN2
b. Navigate to the Sensor 1 Configuration menu, and make any additional settings as needed
c. Repeat for Sensor 2
2) Assign/Map the Device Variables to the HART Variables (PV, SV etc.) Any variable can be
assigned to the PV. However in most cases, BU1-2 or AVG will be used as the PV.
3) Configure the PV Range (PV URV and LRV)
4) Configure the AO’s Range, limits, and fail response
Dual with Mixed Sensors
The THZ
3
or TDZ
3
can be configured for use with two different sensors (for example, T/C and a
RTD).
Follow these steps:
1) Configure the sensor
a. Use the “Configure Input Types” method to select SEN1, and select “Configure
Independently” for
SEN2. Select the proper input mode/type for SEN2
b. Navigate to the Sensor 1 Configuration menu, and make any additional settings as needed
c. Repeat for Sensor 2
2) Assign/Map the Device Variables to the HART Variables (PV, SV etc.) Any variable can be
assigned to the PV. However in most cases, BU1-2 or AVG will 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: While the THZ
3
/TDZ
3
will accept a dual input sensor configuration the following
limitations apply only when using two input sensors:
TDZ
3
[HP] – 2-wire and/or 3-wire sensors. 4-wire sensors (RTDs) cannot be used.
THZ
3
[DIN] (see figure 3.2) - 2-wire and/or 3-wire sensors. 4-wire sensors (RTDs) cannot
be used.
THZ
3
[HPP] (see figure 3.4) – Sensor 1 can be configured as 2-wire or 3-wire sensor.
Sensor 2 is then restricted to a 2-wire sensor.
