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.

Internal Settings
The Failsafe/Non-failsafe relay and the password
security functions are controlled by means of simple
DIP switches and a single jumper inside the unit
housing.
If the unit is equipped with the –AO option, voltage and
current sink/source selection is also inside.
The SPA 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)
• Failsafe/Non-failsafeAlarmFunction (Figure 2)
• CurrentSource/SinkorVoltage(Figure 3)
(Available in AO-equipped SPA only)
NOTE:
SPAs equipped with the –DPDT option make
use of switches 1 and 2 only (see Figure 2).

Programming the SPA
AC Input AlarmTrips
The SPA operating parameters are set, and the set-
tings are stored in on-board, non-volatile EEPROM.
There are four push buttons on the unit front panel;
VIEW, SELECT, an UP arrow, and a DOWN arrow.
Together with the prompting messages displayed on
the LCD, these are used to access menus, and view/
change the settings for:
• Select Functional Setting (Linear Mode or Cus-
tom Mode) and, if selected, set Custom Mode
Engineering units.
• ScaleInput—SmartScaling

Main Menu: View Settings
Figure 4 gives an overview of the first level of menus
used to configure the SPA.
On power-up, the AC-input SPA defaults to a display of
the measured value. Pressing the VIEW 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 (see Figure 1), SELECT will access
either the first screen in the main configuration menu,
“CONF OPTS”, or the password code query screen,
“ENTR PASS”.
Once the Main Menu has been accessed, the up and
down arrow buttons are used to move through all of
the sub-menus in a loop. Pressing the SELECT button
accesses the screen of the sub-menu currently shown
on the LCD.

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.
