Introduction
This is the Users’ Manual for Moore Industries’ SPT,
Site-Programmable Temperature Transmitter. The SPT
accepts inputs from thermocouples, RTDs, or millivolt
or resistance (ý) sources in a host of sensor types and
connection schemes. It provides isolated, linearized (or,
selectably, non-linearized), process-ready output in
several common ranges, and can be readily switched to
operate as either a current or voltage source, or as a
current sink.
The SPT’s configurability makes it practical for use as
a “generic” transmitter — a single unit that can be
stocked, and set on-site to fulfill the requirements of
several different signal conditioning applications within
a process or plant. SPTs can also serve as replace-
ments for installed transmitters from other manufactur-
ers.
Unit setup is quick, intuitive, and flexible. Most opera-
tion settings can be viewed and/or changed using push
buttons and a series of simple menus displayed on the
unit’s front panel LCD. Source/sink output settings, as
well as failsafe or non-failsafe alarm function (with the
optional alarm output) are controlled by a set of DIP
switches that are located with a security jumper inside
the housing behind a sliding panel. This makes disas-
sembly of the unit unnecessary.
The following guidelines are used throughout the
manual:
WARNING – Hazardous procedure or condition that
could injure the operator.
Caution – Hazardous procedure or condition that could
damage or destroy the unit.
Note – Information that is helpful for a procedure, con-
dition, or operation of the unit.
Total Sensor Diagnostics
The SPT incorporates a patented input circuit that elimi-
nates much of the time consuming, trial-and-error work
of troubleshooting sensor networks. Total Sensor Di-
agnostics (TSD) continuously monitors the status of both
the input sensor (or sensors) and wiring.
If a wire breaks, or the sensor fails, a front panel LED
changes color to flag the problem, and the LCD displays
a message telling where the failure has occurred. In
multiple RTD or direct ohms input applications, the SPT
messages indicate which sensor has failed, or if a wire
is broken.
These diagnostic messages allow the user to distinguish
between failures of one of the wires or in the sensor itself.
In multiple sensor applications, the SPT can even dif-
ferentiate between one wire and another.
In addition to these indications, the C option enables
the SPT to provide a contact-closure alarm output that
trips in the event of a sensor failure.
Universal Mounting Capability
The unit is housed in a “universal” DIN case that can be
mounted on both 32mm G-type (EN50035) and 35mm
Top Hat (EN50022) DIN rail. The Installation section of
this manual gives unit dimensions.
Programmable Features
No hand-held configurator or sophisticated bench equip-
ment is needed to get the SPT up and running. Unit
control is done with four push buttons on the front panel.
The standard SPT handles a variety of inputs, outputs,
and multi-sensor applications:
•Inputs – RTD type and number of wires, T/C
type, direct mV or resistance (ohms); reference
junction compensation on/off, linearization on/off.
• Outputs – 4-20mA (source or sink), or 1-5V,
configurable to drive upscale or downscale on
sensor failure. Optional SPDT relay is
configurable as failsafe or non-failsafe, with high
or low alarm function.
• Differential or Averaging – Multiple sensors
(direct ý or RTDs) can be connected to provide
output based on differential inputs, or the
averaging of two or more sensors.
• Smart-Ranging – An innovative operating
feature allows the user to “program in” zero and
full scale values. This eliminates the need for
elaborate calibration setups.

Options
The following list gives details on the options in the Or-
dering Information table. For information on the avail-
ability of options not listed here, or for help in selecting
the type of SPT best suited to your application, always
consult with your Moore Industries Sales Representa-
tive, or call the factory.
C Option — Contact Closure Output. SPDT form 1C
relay output, rated 5A @ 250Vac or 24Vdc, or 0.5A @
125Vdc,non-inductive,50/60 Hz. 700msec max. re-
sponse time for step change on input with trip point at
midpoint of step. Field-selectable normally open/normally
closed terminals and high/low and failsafe/non-failsafe
selections provided.
EPOption—Externally Powered. For user convenience,
units with this option are configured at the factory to sink
4-20mA current, 40Vdc, max. This is typically called for
if other equipment in the application is to supply power
to the SPT. EP-equipped units retain the capability to be
switched from sink to source.
SPT Model Numbers
To order additional or replacement modules for your
system, use the information shown in bold text in the
Ordering Information Table. Specify the following in
order:
Product / Input / Output / Power / Option / [Housing]
• For the standard SPT:
SPT / TPRG / 4-20MA / U [DIN]
This is a programmable temperature T/C input unit. It
sources 4-20mA output. Other defaults on this unit in-
clude upscale drive burn-out protection. This is the stan-
dard SPT that is shipped when the configurations are not
specified. This unit, like all SPTs, retains its field
configurability, regardless of any factory setup.
• For a unit with a specific factory-set input and
range (100ý Platinum RTD with a 3916, –200 to
500°C, for example) specify:

Unit Setup
Operationally, the SPT is a very flexible device. Most of
its operating parameters can be set by the user, and
Moore Industries has made every effort to make setup
quick and intuitive. Bear in mind, however, that because
there is so much about the SPT that can be controlled or
set by the user, it may take a few runs through the setup
routine to become comfortable with the procedure.
It is possible to order the SPT pre-configured according
to specification, directly from the factory. Even if factory
settings have been ordered, however, it is a good idea
to run through the setup routine in order to verify that
parameters have been set according to preference. It is
easier to take a few minutes to check settings prior to
starting up your process than it is to dismantle that pro-
cess because something was inadvertently overlooked.
Internal Settings
The password security and voltage and current
sink/source selections of the standard SPT are controlled
by means of simple DIP switches and a single jumper
inside the unit housing.
If the unit is equipped with the C option for an alarm output,
the alarm’s failsafe/non-failsafe function is also controlled
by internal DIP switches.
The SPT housing is fitted with a sliding access door in its
bottom panel. Figures 1, 2, and 3 show the panel and the
location of each of the controls for setting:
• Password Security ON/OFF (Figure 1)
• Current Source/Sink or Voltage (Figure 2)
• Failsafe/Non-failsafe Alarm Function (Figure 3)
Available with C-equipped units only.

The SPT Menus
SPT operating parameters are set, and their settings
stored in on-board, non-volatile memory. There are four
push buttons on the unit front panel. Together with the
messages displayed on the LCD, these are used to
access menus and effect changes to the settings for:
• Input Sensor Type and Range
• Engineering Units Displayed, and other Options
• Alarm Functions (C-equipped units only)
• Password (Menus/Settings Security)
• “Smart Ranged” Zero and Full Scale
• Standard Ranged Zero and Full Scale
• Actual Output Trim
Main Menu/View Settings
When first powered up, the SPT defaults to a display of
measured value. Pressing VIEW accesses a series of
displays that show, in succession, the settings currently
stored in unit memory for Zero, Span, Alarm Setpoint and
High/Low operational setting, if equipped with the alarm
option.
If the security password jumper is not installed, (the
jumper is stored) pressing SELECT accesses the first
configure menu, CONFIGURE SENSOR (see figure 4).
If the jumper is installed, the SPT asks for a password
with the ENTER PASSWORD menu (see Figure 5). Then
with the password correctly entered, returns to the main
menu at CONFIGURE SENSOR.
Once inside the main menu level, the up and down arrow
buttons are used to move through the various menus in
a loop. The SELECT button accesses the associated
sub-menu.
Hitting SELECT from the “CONF EXIT” screen returns to
the display of the measured process variable.

“SET FAIL” and the “C” option
The SPT’s standard Total Sensor Diagnostics distin-
guishes between sensor failure and an alarm condition
on the measured process variable. If a sensor fails, the
unit output will drive in the direction specified in the “SET
FAIL” menu, and if equipped with the C option, can also
produce an alarm output.
To produce a sensor failure alarm, set both the unit “SET
FAIL” and “ALRM HI LO” parameters high or low. The
procedure for choosing high or low alarm can be found
under the explanation of the Configure Alarm menu,
“CONF ALRM”, following this section. Table 2 shows
how the C option works with the SPT during sensor fail-
ure.
To set failure sensor alarm and alarm output:
II
1. From the “SET FAIL” screen, press
SELECT.
2. Use the up or down arrow to toggle
the display between “FAIL HIGH”
and “FAIL LOW”.
3. Press SELECT to enter the setting
into memory. Choosing “FAIL HIGH”
configures the unit’s output to drive
to full scale in the event of an open
input. With “FAIL LOW”, the output
is driven downscale to zero.
If equipped with the Alarm option,
the optional unit relay will also trip if
configuredfor:
• High alarm with “FAIL HIGH”
• Low alarm with “FAIL LOW”
II
Configure Alarm
This menu sets the parameters of the SPT alarm, which
is present only when the unit is equipped with the C option.
Selections for trip point, deadband, delay, and high/low
function are made in this menu. If the C option is not
present, the SPT will automatically bypass this menu.
Figure 8 gives an overview.

Figure 9. How Alarms Work with the Process Input
Alarm Terminology
If the SPT to be installed is equipped with the alarm option,
Moore Industries suggests that all users take a few
moments to become familiar with some of the terms
associated with the use of process instrumentation
alarms.
Figure 9 illustrates the way the SPT alarm operates. For
more in depth information, contact the factory for a copy
of the publication “ Alarm Trips: The Ups and Downs ”.
Trip Point is the process input level at which the user
wants an alarm relay to change state, typically going into
an alarm condition, or “ tripping ”. The SPT alarm trip point
is set by the user.
High Alarms trip when the process input goes above
the trip point. Low Alarms trip when the process input
drops below the trip point. The SPT alarm output can be
set by the user to function as either a high or low alarm.
Reset Point is the process input level at which the user
wants an alarm relay to change state, going from alarm
to non-alarm. The reset point is not necessarily the same
as the trip point, because most applications call for a buffer
zone or “ deadband ” around the trip point to allow for
minute fluctuations in the process input.
Deadband is the range in which an alarm relay remains
in an alarm condition even after the monitored process
variable input has returned to a safe level, at or below/
above the trip point setting. Deadband is not required,
but remember that when an alarm is configured without
one, its trip point and reset point are the same. The
deadband of the SPT is set by the user.
The relays of a Failsafe Alarm are de-energized when
tripped, energized when the process input is at a
non-alarm level. Non-failsafe Alarm relays are ener-
gized when tripped, de-energized when the process in-
put is at a non-alarm level. The SPT alarm option can be
switched from failsafe to non-failsafe at any time by the
user.
