The SPA AC Input AlarmTrip
This is the users’manual for Moore Industries’ family
of SPA Site-Programmable AC Current and Voltage
Alarms. The SPA monitors a process input or inputs
and provides user-configurable, contact closure
outputs whenever that input falls outside a user-set,
high or low trip point. SPAs are typically used to
activate a warning light, bell, or buzzer; or to initiate
a system shutdown, thus acting as a simple, but
highly reliable and effective means of safe-guarding a
process.
The following guidelines are used in this 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.
Programmable Inputs
The Programmable AC Current & Voltage unit, or
SPA AC, handles either current or voltage inputs in any
user set span in a 0-250VAC or 0-5AAC range.
Programmable Outputs
The SPA AC can be equipped with an analog output
option to provide either a 1-5V or 0-20mA output.
Analog output equipped units are set by the user to
provide either current (switchable between source or
sink modes), or voltage.
The source/sink setting for the optional analog output
is controlled by DIP switches that are located behind
an easy-to-remove access panel inside the unit’s
housing.
Programmable Input Failure Alarms
SPA alarm setup is quick, intuitive, and flexible. Most
unit operating parameters can be viewed and/or set
using push buttons and a series of simple, “plain
English” menu prompts displayed on the integrated
front panel LCD.
Failsafe or Non-failsafe alarm functioning and
source/sink settings for the optional analog output
are controlled by DIP switches that, together with
a security jumper, are located behind an easy-to-
use access panel inside the unit housing. Unit
disassembly is unnecessary.
Universal Mounting
The SPA 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 the dimensions of the
housings for the various alarm configurations.

Main Menu: Password
This menu is bypassed if the Password Security
Jumper is not installed (see Figure 1). If the jumper
is installed, the menu comes up when SELECT is
pressed from the display of the process variable input.
Main Menu: Configure Options
The Configure Options menu allows the user to
choose between Linear and Custom modes of
functioning.
Linear Function. In its Linear Mode (LINR), the SPA
behaves much like a simple input meter. The display
shows the input in either AAC or VAC, depending on
the type of SPA. Its scaling is tied to any input scaling
performed (set in another menu). If equipped with the
–AO option, SPA output can be scaled independently
with respect to the input.
Custom Function. The Custom Mode sets the unit up
for independent programming of input scaling, display
scaling, and, if equipped with the –AO option, output
scaling. In Custom Mode, the user can select °C, °F,
% of scale, Blank (for raw display); or a user-specified,
4-place engineering unit, set at the factory.
Also, if Custom Mode is selected, the user can select
either linear or non-linear display scaling, which
enables a user-programmed, 20-point linearization
curve set in a separate menu.
NOTE:
The SPA’s Linear Mode and its linearizing
of the Custom Mode functioning are not the
same.
Follow the instructions below to select the correct
function. See Figure 5 for details.
1. SELECT the “CONF OPTS”, then with
“SET FUNC”showing on the LCD, use the
arrow buttons to toggle between“CUST FUNC”
and “LINR FUNC”. Refer to the explanation
above for information about each of the
operating modes.
2. Press SELECT to choose the desired mode.
If you selected“LINR FUNC”, the LCD will
prompt you to exit this menu;if you selected
“CUST FUNC”, continue to step 3 to set up the
custom linearization curve.
3. Press SELECT to begin the process of setting
the desired engineering units to be displayed
during SPA operation. Select the appropriate
engineering units with the SELECT button.
This brings up a sub-menu that allows the
user to choose between a linearized or non-
linearized display of the selected, custom
engineering units.
6. Use the arrow buttons to toggle linearization
on or off, then press SELECT to go to “EXIT
OPTS”.
7. Press SELECT again (from “EXIT OPTS”) to
return to the Main Menu.

Main Menu: Scaling Input “Smart Scaling”
This feature of the SPA allows users to set the zero
and full scale values of the input from the intended
application without having to connect the unit to any
calibration equipment.
Once the Zero and Full values are set, the SPA auto-
matically routes the user to the next appropriate menu;
Scale the Display, for Custom Mode users; Scale the
Output, for Linear Mode users (with AO-equipped
SPAs); or Configure Alarms, for Linear Mode users
whose units are not equipped with analog output.
Follow the directions below to scale the input.
1. SELECT the “SCLE INPT” menu.
2. SELECT the “SET ZERO”menu, and use
the arrow buttons to set the display to show
the known zero scale input from the intended
application. Holding the button accelerates the
display change. Press SELECT.
3. SELECT the “SET FULL” menu, and use
the arrow buttons to set the display to show
the known full scale input from the intended
application. Holding the button accelerates the
display change. Press SELECT.
4. Scroll to “EXIT SCLE”, and press SELECT.
If the SPA Custom Mode was selected in the
Configure Options menu, the next menu shown
will be Scale the Display, since in Custom
Mode the input, display, and output (if present)
are independent.
If the SPA Linear Mode was selected in the
Configure Options menu, the next menu shown
will either be Scale Analog Output, for units
equipped with an –AO option, or Configure
Alarms.

Figure 10. The Enter Custom Curve (Custom Linearization) Menu
Main Menu: Enter Curve
(Entering Segment Endpoints
in Custom Mode)
Using this menu the user can program up to 20 lin-
earization points into non-volatile SPA memory. This
capability works exclusively with the unit’s Custom
Mode to make the SPA display linear with respect to
its scaled input. When enabled (in the “CONF OPTS”
menu, discussed earlier), the SPA’s Custom Mode
sets the unit to display the linearized input value in the
user-set engineering units.
As mentioned, the “ENTR CURV” menu is active only
when the SPA’s “CUST FUNC” selection has been
made in the Configure Options menu.
IMPORTANT:
Input zero and full scale as well as display
zero and full scale must be programmed prior
to programming the linearization curve.
The procedure consists of defining the number of
points that are to constitute the linearization curve,
then specifying first the input, then its corresponding
display value at each point.
The “rules” for entering points are:
• Xz<Xn<Xn+1<Xn+2<...<Xn+19<Xf
Where Xz=Input zero, in this case, 0A;
and Xf=Input full scale, in this case, 5A;
Xn, Xn+1 through Xn+19 = Input curve
• Yz<Yn<Yn+1<Yn+2<...<Yn+19<Yf
WhereYz=Display zero, in this case, 0%:
andYf=Display full scale, in this case, 100%;
Yn,Yn+1 throughYn+19 = Display curve
NOTE:
The endpoints of the curve must
fall within a range defined by the zero and full
scale values for both the input and the display.
Figure 10 shows the menu.

Main Menu:Trim Analog Output
This procedure is only required on those SPAs
equipped with the –AO option. Figure 12 shows the
setup needed. Figure 13 shows the menu.
Connect the unit as shown, apply the appropriate
power, and allow 5 minutes for stabilization/warm-up.
1. SELECT the “TRIM OUT” menu.
2. Use the arrow buttons to choose the level, zero
or full scale, that is to be trimmed.
3. Press SELECT to begin the trim process. The
display will begin to flash the “TRIM ZERO”
or “TRIM FULL” screen, depending upon the
option chosen in step 2.
4. While monitoring the reading on the meter, use
the arrow buttons to adjust the output to the
desired level. Use the meter in the setup to
monitor the output as the output is adjusted.
5. When the output is set as desired, press
SELECT. This sets the adjustment into SPA
memory, and brings up either the next output
level to be adjusted (repeat steps 3, 4, and 5),
or “EXIT OUT” if both zero and full scale output
have been adjusted.

Main Menu: Configure Alarm
The Configure Alarm menu sets the trip point(s),
Deadband, Trip Delay, High or Low Alarm function, and
Latching or Non-Latching operation.
After selecting the “CONF ALRM” menu, use the
arrow buttons to scroll through the alarm operation
parameters. Press SELECT to access the settings for
the displayed parameter.
Trip Point(s)
There are two options for setting the trip points of the
installed alarms,“ENTR TRIP” and “APLY TRIP”.
In the “ENTR TRIP” menu, the user employs the Smart
Ranging feature of the SPA, entering the desired trip
point with the front panel push buttons.
In the “APLY TRIP” menu, the SPA must be set up with
calibration equipment (see Figure 7, page 12).
The unit then “captures” its trip point from the input of
an adjustable source. The process for this is similar to
capturing the input: hookup the SPA into a calibration
setup, set the SPA’s menu appropriately, apply the
amount of power that you would like the trip point set
at, and press SELECT.
Other Configuration Options
Setting the deadband, delay, high/low trip, and latching
or non-latching options is a simple matter of using the
front-panel buttons to select the appropriate values.
