General Information
The SP714-S2i is a meter-mounted pulse amplier that amplies and conditions low amplitude signals, typically
produced by the magnetic pickup coil of a Sponsler turbine owmeter. The SP714-S2i transforms the low power input
signal from the pickup coil into square-wave output signals with enough energy to travel a greater distance and be
detected reliably by the electronic device, such as a ow computer or an electronic register.
The SP714-S2i includes an input signal sensitivity adjustment (R1) that permits the SP714-S2i to discriminate
between an input signal and noise by increasing or decreasing the input signal amplitude necessary to be processed
as a valid signal. This, in conjunction with being directly mounted onto the turbine ow meter, allows the SP714-S2i to
operate effectively in noisy environments.
The SP714-S2i also includes diagnostic tools. The diagnostic test oscillator (SW2) enables the operator to verify the
ampliers operation without a signal source. The green LED (D1)indicates the power supply status. The red LED (D2)
indicates the signal frequency status.
In order to maintain IECEx compliance, the SP714-S2i is connected to the turbine owmeter boss. The
turbine meter and SP714-S2i assembly is pressure tested at the factory, then shipped as an assembly.

INSTALLATION OVERVIEW
In order to maintain IECEx compliance, the SP714-S2i is shipped as part of an assembly with a Sponsler turbine
owmeter. A complete installation of the owmeter and pulse amplier assembly includes the physical installation of
the owmeter and the electrical installation of the SP714-S2i. Guidelines for the physical installation of the owmeter
can be found in the Sponsler turbine owmeter manual. Instructions for the electronic installation of the SP714-S2i are
included in this manual.
1. Install Sponsler turbine owmeter (with SP714-S2i) into system piping. Sponsler Turbine Flowmeter Installation Manual
2. Wire the SP714-S2i to a pulse acquisition device and set the S1 switches to the preferred output signal characteristics. Page 7
3. Perform eld test and adjust the input signal sensitivity (if necessary). Page 11
Use the proper cable glands, conduit connectors, cables,
conduit, and installation procedures when wiring the SP714-S2i.
Installations must be in full accordance with national and local
codes to maintain the hazardous location ratings on the product.
Observe National and Local Codes
WIRING THE OUTPUT SIGNAL CONFIGURATIONS
The SP714-S2i can be set to one of three congurations: 2-wire Standard, 3-wire TTL Sourcing, and 3-wire Open
Collector. The 2-wire Standard conguration translates the output signal from the turbine owmeter’s pickup coil into
a current value. 2-wire connections are effective transmitting the signal over long distances. The 3-wire TTL Sourcing
conguration translates the output signal from the turbine owmeter’s pickup coil into a voltage value. The output
of the 3-wire TTL Sourcing conguration is driven either positive or negative internally. The 3-wire Open Collector
conguration translates the output signal from the turbine owmeter’s pickup coil into a voltage value. The output is
driven by an “Open Collector” transistor.
Each conguration requires a specic positioning of the two S1 switches, specic
wiring connections (to the power supply and the pulse acquistition device), and a
resistor(s) spliced into the +V leg from the power supply (optional for the 3-wire TTL
Sourcing conguration).
The best conguration for your application is determined by the specications of the
pulse acquistion device (typically a ow computer or electronic register) receiving
the SP714-S2i signal and the electrical characteristics of the application.

2-WIRE STANDARD
The 2-wire Standard conguration translates the output signal from the turbine owmeter’s pickup coil into a current
value. The 2-wire Standard conguration produces an output signal using a resistor to convert the electrical current
variations into voltages. In this conguration, the power supply travels on the signal wire. 2-wire connections are
effective transmitting the signal over long distances.
1. Remove the SP714-S2i housing cover.
2. Pull the SP714-S2i board from the housing for access to the TB1 terminal block and the S1 switches.
3. Attach proper cable glands and/or conduit connectors to the SP714-S2i, the pulse acquisition device, and DC power supply.
4. Run the wires (through proper conduit) between the SP714-S2i, the pulse acquisition device, and DC power supply.
5. Set the rst S1 switch to the
ON position and the second S1
switch to the OFF position.
6. Splice the resistor onto the +V
leg from the DC power supply.
The value of the resistor can be
determined using the information below.
7. Wire the SP714-S2i to the pulse
acquisition device and DC
power supply as indicated in the
schematic.
8. If necessary, adjust the input
signal sensitivity (R1), activate
the diagnostic test oscsillator
(SW2), and/or check the
diagnostic operational LEDs (D1
& D2). See page 11.
9. Coil the wires underneath the
CPU board and place the board
inside the housing, ensuring
the wires are not pinched, and

The 3-wire TTL Sourcing conguration translates the output signal from the turbine owmeter’s pickup coil into a
voltage value. The output of the 3-wire TTL Sourcing conguration is driven either positive or negative internally. Note
that the name “TTL” is misleading because the output switches from 0V to +Vs, not 0V to +5V as the TTL standard
indicates. In the SP714-S2i, “TTL” indicates that the output is driven in both the positive and zero volt cases. A pull-
up or pull-down resistor is optional in the 3-wire TTL Sourcing conguration; however, a resistor can be installed to
prevent damage from faults.
1. Remove the SP714-S2i housing cover.
2. Pull the SP714-S2i board from the housing for access to the TB1 terminal block and the S1 switches.
3. Attach proper cable glands and/or conduit connectors to the SP714-S2i, the pulse acquisition device, and DC power supply.
4. Run the wires (through proper conduit) between the SP714-S2i, the pulse acquisition device, and DC power supply.

The R1 Input Signal Sensitivity Adjustment is a valuable tool that, in addition
to SP714-S2i being directly mounted to the turbine meter, allows effective
operation in noisy environments. The R1 is a potentiometer that sets the
amplitude of the input signal (from the pickup coil) that the SP714-S2i will
accept as a valid pulse.
Adjusting R1 allows the SP714-S2i to differentiate between the input signal
and any noise in the system. Turning the R1 clockwise decreases the
amplitude of the input signal required for a valid pulse, and turning the R1
counterclockwise increases the required amplitude.
The detection level of the R1 potentiometer is set at approximately 17 mV
rms at the factory. A red varnish is applied to the potentiometer screw to seal
the factory setting.

Diagnostic LEDs
There are two Diagnostic Operational LEDs (D1 and D2) on the SP714-S2i PC board that indicate the current
operational status of the preamplier. The green LED (D1) indicates the power supply status. When the green LED is
on, the power supply is sufcient. When the LED is dim or ashing, the preamplier does not have sufcient power.
The red LED (D2) indicates the status of the signal traveling through the preamplier. The red LED ashes at the
same rate as the frequency as the signal passing through the SP714-S2i. If the LED is not ashing, no signal is
passing through the amplier. If the signal frequency is above 40 Hz, the light will ash very quickly and the LED will
appear to be constantly illuminated. If the input into the SP714-S2i stops on a positive portion of the signal pulse, the
LED will be illuminated constantly.
The SW2 Diagnostic Test Oscillator veries that the SP714-
S2i is operational. To activate the test, press the SW2 push
button. A 10 Hz signal will be introduced into the SP714-
S2i signal output pins (TB1). For best results, use the SW2
Diagnostic Test Oscillator without the presence of the pickup
coil signal.
If an input signal from the pickup coil is present, the 10 Hz
signal from the SW2 can disrupt the SP714-S2i output signal
and an error will be detected by the pulse acquisition device.
Do Not Use the SW2 During Operation
The D1 and D2 LEDs are inoperable in the 2-wire Standard conguration.
Polarity of the connector at the
pickup coil is not important.
Maintenance - CPU Board Replacement
The CPU board (PN 85025) is the only SP714-S2i part available for purchase. If you are replacing the 85025 CPU
board, the wiring harness, which connects the pickup coil and to the SP714-S2i CPU board, must be unplugged from
the old CPU board and plugged into the replacement board, then wired appropriately.
1. Remove the SP714-S2i housing cover.
2. Pull the CPU board from the housing, disconnect the
wires to the power supply and the pulse acquisition
device, and unplug the wiring harness.
3. Plug the wiring harness into the replacement CPU board,
wire the replacement CPU board to the power supply
and the pulse acquisition device, set the board into the
housing, and replace the housing cover. See pages 7-10 for
detailed instructions.
