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 replace­ments for installed transmitters from other manufactur­ers.
Unit setup is quick, intuitive, and flexible. Most opera­tion 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 disas­sembly of the unit unnecessary.
The following guidelines are used throughout the manual:
WARNING

Caution
damage or destroy the unit.
Note
dition, or operation of the unit.
Total Sensor Diagnostics
The SPT incorporates a patented input circuit that elimi­nates much of the time consuming, trial-and-error work of troubleshooting sensor networks. Total Sensor Di­agnostics (TSD) continuously monitors the status of both the input sensor (or sensors) and wiring.
– Hazardous procedure or condition that
– Hazardous procedure or condition that could

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 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 dif­ferentiate 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.
where
the failure has occurred. In
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 equip­ment 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.

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]
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. re­sponse 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.
EP Option — 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.
The Interface Solution Experts
• 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 in­clude upscale drive burn-out protection. This is the stan­dard 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:
SPT / R5 - (–200) - 500C / 4-20MA / U [DIN]

SPT
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 pro­cess because something was inadvertently overlooked.
Figure 1. Setting the Internal Jumper for Password Security ON/OFF
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)

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 distin­guishes 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.
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 configured for:
To produce a sensor failure alarm, set both the unit “SET FAIL” and “ALRM HI LO” parameters high or low. The
• High alarm with “FAIL HIGH”
procedure for choosing high or low alarm can be found under the explanation of the Configure Alarm menu,

SPT
Alarm T erminology
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 “
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 “ 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.
Figure 9. How Alarms Work with the Process Input
Alarm Trips: The Ups and Downs
tripping
”. The SPT alarm trip point
”.
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 in­put is at a non-alarm level. The SPT alarm option can be switched from failsafe to non-failsafe at any time by the user.

Normal is the term used to describe the “shelf-state” of
relay contacts. The contacts of a Normally Open relay are open (infinite resistance) when the relay is not ener­gized. The contacts of a Normally Closed relay are open when the relay is energized (closed when not energized).
Note:
Sometimes a non-alarm input level is referred
to as being in a “normal” condition. This
practice is intentionally avoided in this
manual. Do not confuse the term “normal”, as
in Normally Open or Normally Closed, with a
non-alarm input condition. In this manual,
“normal” is an exclusive reference to the shelf
state or quiescent state of an alarm’s relay
contacts, whether open or closed.
TSD, the C Option and the SPT Alarm
Total Sensor Diagnostics, TSD, is standard on all SPTs. This innovative, embedded feature monitors input con­tinuously, and displays messages on the front panel LCD to let the user know not only if there is a problem with the input(s), but PUT LED also changes color (from green to red) if there is an input problem.

2. Press SELECT to access the settings for the alarm, or use the arrow buttons to access the “ALRM EXIT” screen, and press SELECT to return to the main menu at “PASS WORD”.
3. After pressing SELECT in step 2, use the arrow buttons to scroll through the alarm parameters:
• Enter trip point
• Input trip point
• Enter deadband
• Enter delay
• Set high/low function
Press SELECT to access the settings for the displayed parameter. It is recommended that the parameter settings be entered into SPT memory in the order that they come up in this step (shown above). This is not required, however.

Sensor Failure and Alarm Output. To complement
TSD, the C option enables the SPT to provide alarm output on sensor failure.
Note:
Without the C option, the SPT cannot provide
an alarm output on sensor failure. But, the
analog output does react to sensor failure.
Assuming the appropriate options are present, to pro­vide a sensor failure alarm, the SPT’s HI/LO alarm set­ting and its upscale/downscale drive selection (“SET FAIL”) must be configured to work in concert. The set­tings for both parameters must agree.
Table 2 summarizes the way the C-equipped SPT func­tions in response to sensor failures.
To set the parameters of the SPT alarm:
Note:
There are two options for setting the trip
points of the alarm on the C-equipped SPT,
“ENTR TRIP” and “INP TRIP”.
“ENTR TRIP” allows the user to use the front
panel push buttons to enter the desired trip
point value into unit memory.
“INP TRIP” requires that the user incorporate
the SPT into a calibration setup to “capture”
the trip point value using an adjustable
input source.

Installation
The SPT is housed in a universal DIN-style case that mounts easily on both G-type and Top Hat rails.
Mounting the SPT
To mount the SPT on Top Hat DIN rail, seat the upper extrusion on the back panel over the top of the rail and pivot downward until the housing locks into place.
To mount the unit on G-type rail, seat the extrusion un­der the top lip of the rail and pivot downward.
When mounting SPTs in multiple unit scenario like a rack or cabinet, make sure to allow adequate vertical spacing for pivoting the units. Figure 16 shows the unit’s dimen­sions.
Figure 16. Dimensions of the SPT
34.5 mm (1.36 in)
Recommended Ground Wiring Practices
The following ground wiring practices must be followed to ensure proper performance of the SPT:
• Any Moore Industries’ product in a metal case, enclosure or housing should be grounded. Units in DIN housings, for example, should be mounted on a grounded rail.
• All input signals to, and output signals from Moore Industries’ products should be wired using a shielded, twisted pair technique. Shields are to be connected to an earth or safety ground at the unit itself.
• The maximum length of any unshielded input and/ or output signal wiring is 2 inches.

SPT
Operation
Once connected to sensors, annunciators (or other dis­crete devices), and appropriate power, the SPT begins to function according to its internal switch settings and the configuration stored in its non-volatile internal memory.
Unit configuration data, stored in memory, is monitored continuously. Any changes made to operating param­eters controlled by choices made in the SPT menu sys­tem take effect immediately.
The settings of the internal DIP switches and security jumper may also be changed at any time. Changing the Security Jumper setting, however, requires that unit power be cycled off and on before taking effect. The settings for source/sink and failsafe/non-failsafe take effect right away.
LED’ s
The front panel of the SPT incorporates a set of LEDs that are labeled according to function. These indicators provide a quick reference for input condition during nor­mal unit operations. Table 4 illustrates the different con­ditions of the LEDs.
Note:
The state of the SPT relay in alarm or non-
alarm is determined by the failsafe/non-
failsafe setting of the unit’s internal DIP
switch.
Do not confuse the state of the LED with the
state of its associated relay.
Failsafe relays are ON (energized) when input
is in a non-alarm condition (green LED).
Failsafe relays are OFF (de-energized) when
input is in alarm (red LED).
Non-failsafe relays are ON (energized) when
input is in alarm (red LED), and OFF
(de-energized) when in a non-alarm condition
(green LED).

This design scheme means that, regardless of the relay state, the LEDs associated with the alarm output in the C-equipped SPT will always show red when the input is in alarm, and green in non-alarm.

Error Codes
Every SPT is subjected to an exhaustive battery of op­erational checks and tests prior to its shipment. Occa-
For most problems, it will be necessary to return the unit to the factory. A quick call to Moore Industries will have a temporary replacement unit to you in as little as 24 hours, usually in even less time.
sionally, however, units can sustain damage getting from the factory to the user.
Table 5 lists the error codes, and the action to take if they are displayed on start-up.
The SPT is equipped with a full set of internal diagnos­tics that check unit operation and configuration on power­up. If there are problems with the unit’s microprocessor, or with conflicting settings in memory, the LCD will show an error code.

RETURN PROCEDURES
To return equipment to Moore Industries for repair, follow these four steps:
1. Call Moore Industries and request a Returned Material Authorization (RMA) number.
Warranty Repair – If you are unsure if your unit is still under warranty, we can use the unit’s serial number to verify the warranty status for you over the phone. Be sure to include the RMA number on all documentation.
Non-Warranty Repair – If your unit is out of warranty, be prepared to give us a Purchase Order number when you call. In most cases, we will be able to quote you the repair costs at that time. The repair price you are quoted will be a “Not To Exceed” price, which means that the actual repair costs may be less than the quote. Be sure to include the RMA number on all documentation.
2. Provide us with the following documentation: a) A note listing the symptoms that indicate the unit needs repair b) Complete shipping information for return of the equipment after repair c) The name and phone number of the person to contact if questions arise at the factory
3. Use sufficient packing material and carefully pack the equipment in a sturdy shipping container.
4. Ship the equipment to the Moore Industries location nearest you.
The returned equipment will be inspected and tested at the factory. A Moore Industries representative will contact the person designated on your documentation if more information is needed. The repaired equipment, or its replacement, will be returned to you in accordance with the shipping instructions furnished in your documentation.
