Introduction
This is the user’s manual for Moore Industries’ SPA2
(HLPRG): Programmable Current/Voltage Limit Alarm.
The instrument is configured using a combination of
front panel pushbuttons and a dedicated PC Configura-
tion Program. The SPA2monitors a process variable
and provides up to four, fully user-configurable contact
closure outputs that can be individually programmed to
trip whenever the input falls outside a user-set, high or
low trip point. The SPA2is typically used to activate a
warning light, bell or buzzer; or to initiate a system
shutdown. Thus, the instrument acts as a simple, but
highly reliable and effective means of monitoring and
safe-guarding a process.
About this Manual
Wherever you see a “ Note ”, “ Caution ” or “ WARNING ”
pay particular attention.
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,
condition, or operation of the unit.
Model and Serial Numbers
Moore Industries uses a system of model and serial
numbers to keep track of all of the information on
every unit it sells and services. If a problem occurs
with your SPA2, check for a tag affixed to the unit list-
ing these numbers. Supply the Customer Support rep-
resentative with this information when calling.
Inputs
The SPA2 (HLPRG )(“High Level” Programmable input),
handles either current inputs from 0-50mA (1mA
minimum span) or voltage inputs from 0-10V (250mV
minimum span).
Outputs
Alarms
The SPA2can be ordered with two (-2PRG) or four
(-4PRG) contact closure alarms. Each alarm can be
individually programmed.
2PRG
This is a two relay output with 5A@250Vac or 24Vdc,
50/60Hz non-inductive contact rating. The contact
arrangement is SPDT; however, the -2PRG output is
also available in a DPDT contact arrangement. All
relay contacts (NO, NC and COM) are available for
use. No jumpers are required.
4PRG
This is a four relay output with 5A@250Vac or 24Vdc,
50/60Hz non-inductive contact rating. The contact
arrangement is SPDT. All relay contacts (NO, NC and
COM) are available for use. No jumpers are required.
TX Power
A transmitter excitation power supply (24Vdc
±10%@24mA) is standard on the SPA2 (HLPRG). You
may access this externally at the terminals shown in
Figure 3.
Options
Analog Output (-AO)
The SPA2can be equipped with a scaleable output
option to provide a 0-20mA or 0-10V output. -AO
equipped units are set by the user to provide either
current (user-configurable between source or sink) or
voltage.
Internal Settings
The password security function of the SPA2is con-
trolled by a single jumper inside the top of the unit
housing. You will need to remove the top cover in
order to access the jumper. Refer to Figure 2 for
location and jumper settings.

SPA2Configuration:
Front Panel Pushbuttons
The SPA2 (HLPRG) operating parameters may be set
using front panel pushbuttons and/or Moore
Industries’ PC Configuration Software. This section
describes configuration via the front panel
pushbuttons.
There are three pushbuttons on the unit’s front
panel; UP , DOWN and SELECT . Together with the
prompting messages displayed on the LCD, these
are used to access menus, and to view and change
the settings.
Use SELECT as your “Enter” button, to make your
selections.
Use the UP and DOWN buttons to navigate within
the menus.
Note:
All parameters, except the Custom Curve feature,
can be configured using the front panel pushbuttons.
The Custom Curve table can only be configured
using the PC Configuration Software Program.
Main Menu/View Settings
Figure 4 gives an overview of the Main menu; the
View menu is shown in Figure 5.
Upon power-up, the SPA2defaults to a display of the
measured value. Pressing the DOWN button ac-
cesses a series of displays that show, in succession,
the settings currently stored in unit memory.
Depending upon whether or not the Security Jumper
has been installed (Figure 2), pressing SELECT will
access either the first screen in the main configuration
menu, “CONFG INPUT”, or the password code query
screen, “ENTER PASS”.
Once the Main Menu has been accessed, the DOWN
button is used to move through all of the sub-menus in
a loop. Pressing the SELECT button accesses the
first screen of the sub-menu shown on the LCD.
Password
This menu is bypassed if the Password Security
Jumper is not installed. If the jumper is installed, the
menu comes up when SELECT is pressed from the
display of the process variable input. To access the
security jumpers, you must remove the top cover
(refer to Figure 2). The menu is shown as part of
Figure 4. Refer to the Password Configuration section
of this manual for a more detailed description of the
password feature.
1. If the jumper is installed, pressing SELECT
from the display of the process variable input
will bring up the “ENTER PASS” screen.
2. Press SELECT again to enter the “PASS”
screen. Use the UP and DOWN buttons to
enter “55”, the default screen for this point in
the menu.
3. If a password has been set (four characters,
maximum), use the UP or DOWN buttons to
display the correct password.
When the correct password number is
displayed, press SELECT .
Note:
If the correct password is not known, the unit
settings can be viewed, but not changed.
4. If you have entered the correct password, the
input configuration menu, “CONFG INPUT”, will
be accessed. If not, the display will show a
“VIEW ONLY” message.
5. From “VIEW ONLY”, press SELECT to go back
to the process variable input. Use the UP and
DOWN buttons to view the settings in the
various menus. The “VIEW ONLY” mode locks
out any attempt to make changes to the
settings.
Note:
The menu to set or change the password stored in
SPA
2
memory is presented in the Password
Configuration section of the manual.

Configuring the Options
Figure 7 gives an overview of the Options
Configuration menu.
You may configure the process variable display,
decimal places, 50/60Hz filter selection, broken wire
detection and the scaling mode from this menu.
To configure the options of the the SPA2:
1. At the “CONFG OPTNS” screen, press

5. Next, the “SET DPS” display appears. Press
SELECT. Scroll through the available choices
by using the UP and DOWN buttons and press
SELECT once you have made your selection.
6. “SET FILTR” appears; press SELECT . Here,
you must select the proper line frequency of
your AC source–50Hz or 60Hz; press SELECT .
7 . When “SET BWIRE” appears, press SELECT
to enter the menu. You must choose whether
or not to enable Broken Wire Detection. Press
SELECT.
Broken Wire Detection– The SPA2monitors
your process variable. If the monitored value
falls equal to or below a set value, then a state
of Broken Wire is declared.
Caution:
Moore Industries does not recommend use of
broken wire detecton if using a voltage input on the
SPA
2
. Various factors may hinder the unit’s
performance and greatly slow the broken wire
response time. If broken wire detection is used on a
voltage input, testing must be done on a regularly
scheduled basis, both with near-end and far-end
open circuits on each of the wires.
Leakage current into a broken wire can prevent the
voltage from dropping to the broken wire threshold.
For example, on a 1-5V input, with a broken wire
threshold of 0.6V, a leakage current of 1microamp
into the broken wire will hold the input voltage at
approximately 1.1V indefinitely. No alarm results
under these conditions.
If the external wiring is long and has significant
capacitance, broken wire response time is slowed
by the RC time constant of the SPA
2
input
resistance and the external wire capacitance. For
example, 1 km of wire with 100pf/m capacitance and
a far-end break, has a capacitance of 0.1microfarad.
The time constant will be 0.11 seconds. Using a
starting voltage of 3V and a broken wire threshold of
0.6V, the threshold is reached in approximately 0.18
seconds. The instrument response time must be
added to this time.
If both leakage and capacitance exist, the time to
threshold can extend greatly. Using a 5V starting
voltage, 0.6V threshold voltage, 1 km of wire and
0.5 microamps leakage current, the threshold is
reached in 0.42 seconds. The instrument response
time must then be added to this time.
8. “SCALE MODE” appears; press SELECT .
Choose whether or not to enable scaling. This
will be configured in the next menu. Select
“SCALE OFF” or “SCALE ON” and press
SELECT.
Scale Mode– This allows you to customize
your display for your application. By example:
if your process is sending a 4-20mA signal to
the SPA2and you wish to view the input as
0-100% then this can be accomplished with the
Scale Mode feature.
9. “EXIT OPTNS” appears. Press SELECT .
Proceed to the “SCALE INPUT” menu.

Scaling the Input
Figure 8 gives an overview of the Input Scaling menu.
Scaling allows you to take your PV (Process Variable)
reading and manipulate it to a more customized dis-
play range. PV is the unit read after selecting your
input type. For example, choosing a Current input
would then produce a PV displayed in mA.
Also known as “Smart Ranging”, scaling of the SPA2
(HLPRG) allows the user to set the zero and full scale
values of the input from the intended application, with-
out having to connect the unit to any calibration equip-
ment.
Continue with the “SCALE INPUT” if you enabled
scaling in the previous menu. To proceed, follow the
steps below.
Note:
When using the front panel push buttons to enter
your scaling values, you may enter only whole
number increments. To adjust your value past the
decimal point, you must use the PC Configuration
Program.
1. At the “SCALE INPUT” display, press
SELECT .
2. Press SELECT at the “INPUT ZERO”
parameter and enter the value you want
displayed when your input is at zero. Press
SELECT.
3. Press SELECT at the “INPUT FULL” screen.
Enter the value you wish displayed when your
input is at full scale. Press SELECT.
If you selected “SCALE OFF” in the “CONFG
OPTNS” menu, the menu skips to Step 6. If
you selected “SCALE ON”, proceed to Step 4.
4. Next, “SCALE ZERO” is displayed. Use the
UP and DOWN buttons to adjust your scaled
zero value. This is the value that will be
displayed when you are at the zero end of your
display range. Press SELECT.
5. “SCALE FULL” appears. Press SELECT to
enter the menu. Enter the value you wish as
your full scaled range– the value displayed
when you are at the full end of your range.
Press SELECT.
6. “EXIT SCALE” appears. If all scaling
parameters have been set, press SELECT.
The next menu selection to appear is “TRIM
INPUT”.

Applying Input (Bench Scaling)
Figure 9 gives an overview of the Apply Input menu.
With Bench Scaling, also called “Standard Ranging”,
inputs are “captured” at their zero and full scale levels
using external, calibrated equipment.
1. At the “APPLY INPUT” screen, press SELECT.
2. “APPLY ZERO” appears. Apply the input you
wish as your zero and press SELECT . Wait
until it is flashed on the display and press
SELECT to capture.
3. Next, “APPLY FULL” is displayed. Apply the
value of your full range and press SELECT .
When this is flashed, press SELECT to
capture.
4. Press SELECT at “EXIT APPLY” and exit the
menu.
Input Trimming
Figure 10 gives an overview of the Input Trimming
menu.
Input trimming increases the measurement accuracy
of the parameter you are trimming by matching the
reading of its actual input to its scaling. The SPA2
offers the use of a factory-configured trimming feature
(“FCTRY TRIM“) or user-set, one-point or two-point
(“USER 1PNT” OR “USER 2PNT”) trimming.
Unit default is “FCTRY TRIM”. If another trimming
selection had been made and you wish to return to the
“FCTRY TRIM” feature, follow the instructions below.
1. Press
SELECT at the “TRIM INPUT” SCREEN.
Once the “TRIM MODE” appears, press
SELECT .
2. “FCTRY TRIM” is displayed, press SELECT.
This takes you to the “EXIT TRIM” screen.
3. To exit, press SELECT .
To input user-specific trim values, perform the
following steps:
1. At the “TRIM INPUT” display, press SELECT .
When “TRIM MODE” appears, press SELECT
again. Use the UP and DOWN buttons to reach
the user-set trimming menus. Press SELECT
once the desired parameter is displayed–
“USER 1PNT” or “USER 2PNT”.
2. “TRIM ZERO” appears. To program, press
SELECT . Your present zero scaling value is
shown and prompts you to “APPLY” your value.
Press SELECT, once your value is present and
flashing at the appropriate input terminals,
press SELECT again . If you selected “USER
1PNT” trimming, “EXIT TRIM” appears. Press
SELECT to reach the “CONFG AOUT” menu (or
“CONFG ALARM” menu if the -AO option is not
enabled). Proceed to Step 3 for “USER 2PNT”
trimming.
3. If you selected “USER 2PNT” trimming, repeat
the instructions in Step 2 for the “TRIM FULL”
setting. Press SELECT when “EXIT TRIM” is
displayed to reach the “CONFG AOUT” menu
(or “CONFG ALARM” menu if the -AO option is
not enabled).
Note:
Trim only the zero and full values entered in the
“SCALE INPUT” menu through the front panel
pushbuttons. To trim values other than those
specified in the “SCALE INPUT” menu, you must
use the PC Configuration Software program.

2. Once you reach the “SET DAMP” field, you
may skip the damping parameter, by using the
Down button to reach the next field. To set
damping, proceed to Step 3.
Damping– Output Damping allows you to
introduce a delay (0-30sec) into the response
of your unit in order to stop momentary input
variations from setting off alarms.
3. To set damping, press SELECT at the “SET
DAMP” display. Use the UP and DOWN
buttons to enter a value between 0 and 30
seconds; press SELECT.
4. Press SELECT at “FAIL MODE” to program
the setting. Choose “FAIL HIGH” or FAIL
LOW”. This sends you to “EXIT AOUT”.
HIGH/LOW– Choosing either of these options
will send the output to a High (23.6mA for
current; 11.0V for voltage) or Low (3.6mA for
current; -0.5V for voltage), respectively.
