Introduction
This is the user’s manual for Moore Industries’
THZ
2
and TDZ
2
(TPRG: RTD, T/C, Ohms, mV and
Potentiometer inputs) Programmable Smart HART
Temperature Transmitter and Display. It contains all of
the information needed to configure, install, operate
and maintain the instruments.
About this Manual
Pay particular attention wherever you see a “
Note
”,
“
Caution
” or “
WARNING
”.
Note
– Information that is helpful for a procedure,
condition or operation of the unit.
Caution
– Hazardous procedure or condition that
could damage or destroy the unit.
WARNING
– Hazardous procedure or condition that
could injure the operator.
The THZ
2
and TDZ
2
The THZ
2
and TDZ
2
are 2-wire (loop-powered), user-
configurable, HART
®
-based temperature transmitters.
Their size, accuracy and compatibility make them the
ideal solution when measurements must be made in
remote or otherwise difficult-to-access locations.
The THZ
2
and TDZ
2
allow for configuration through
two methods. You may use your PC’s RS-232
serial port or USB port and Moore Industries’ PC
Configuration Software (once installed onto your PC).
All configuration parameters are available through the
PC Configuration Software.
The second method is to connect a HART
Communicator and HART modem into your process
loop. You must ensure that your communicator is
configured with the THZ
2
and TDZ
2
Device Description
(DD). You may then configure most parameters
through the Communicator. Custom Curve variables
cannot be entered using the Communicator. They
must be configured using the PC Configuration
Software.
Model and Serial Numbers
Moore Industries uses the model and serial numbers
of our instruments to track information regarding each
unit that we sell and service. If a problem occurs with
your instrument, check for a tag affixed to the unit
listing these numbers. Supply the Customer Support
representative with this information when calling.
