Functional Safety Dual Input Smart HART® Temperature Transmitter
STZ
SECTION 4
Configure Input Types:
Selecting this will enable to configure Sensor 1 and Sensor 2 as follows:
Note:
While the STZ will accept a dual input sensor configuration the following limitations apply
only when using two input sensors:
STZ
[HP]
2-wire and/or 3-wire sensors. 4-wire sensors (RTDs) cannot be used.
STZ [DIN]
2-wire and/or 3-wire sensors. 4-wire sensors (RTDs) cannot be used.
STZ [HPP]
Sensor 1 can be configured as 2-wire or 3-wire sensor.
Sensor 2 is then restricted to a 2-wire sensor.
Sensor 1 Type
[4W RTD]
Selecting this will prompt the Sensor 1 Type menu screen. Here you can select from
Resistance, mV, Potentiometer, RTD,
or
T/C.
Highlight the desired sensor type and hit enter.
-Resistance:
1. Choose from
2 Wire, 3 Wire, or 4 Wire
Connection
2. Select a Resistance value from 4k, 2k, 1k, 500, 250, or 125
3.
Sensor 2 Type
menu will appear (see below)
-mV:
1. Choose from
1k, 500, 250, 125, 62.5, or 31.25
mV
2.
Sensor 2 Type
menu will appear (see below)
-Potentiometer:
1. Choose from
4k, 2k, 1k, 500, 250, or 125ohms
2.
Sensor 2 Type
menu will appear (see below)
-RTD:
1. Choose from
2 Wire, 3 Wire, or 4 Wire
Connection Configuration
2. Select temperature unit from
degC, degF, degR, or Kelvin
3. Select desired RTD and hit enter
4.
Sensor 2 Type
menu will appear (see below)
-T/C:
1.Choose between Enabled or Disabled for RJC Temperature compensation. This
should be enabled for the majority of cases. Disable RJC ONLY if you are using a rare
and old remote reference junction wiring strategy
2. Select temperature unit from the following
degC, degF, degR, or Kelvin
3. A variety of Thermocouples to choose from select desired T/C and hit enter
4.
Sensor 2 Type
menu will appear (see below)
Sensor 2 Type [Off]:
1. Choose from the following menu options O
ff, Same as Sensor 1, or Configure
Independently
.
-Selecting O
ff
will turn Sensor 2 off
-Selecting
Same as Sensor 1,
the configuration parameters from
Sensor 1
will be
copied to configure
Sensor 2
-Selecting
Configure Independently,
this will allow you
configure parameters of
Sensor 2
separately.
(Same menu options as Sensor 1 above)
