Operating precautions
Franklin Fueling Systems (FFS) equipment is designed to be installed in areas where volatile
liquids such as gasoline and diesel fuel are present. Working in such a hazardous environment
presents a risk of severe injury or death if you do not follow standard industry practices and the
instructions in this manual. Before you work with or install the equipment covered in this manual,
or any related equipment, read this entire manual, particularly the following precautions:
IMPORTANT: Always reference the Installation and Owner’s manual that came with the
equipment for the most current, complete installation and safety precaution details. Where
applicable, this manual may contain notations of previous equipment features for your reference
since the release of software revision 1.2.
CAUTION: Use only original FFS parts. Substituting non-FFS parts could cause the device to
fail, which could create a hazardous condition and/or harm the environment.
WARNING: Follow all codes that govern how you install and service this product and the
entire system. Always lock out and tag electrical circuit breakers while installing or servicing
this equipment and related equipment. A potentially lethal electrical shock hazard and the
possibility of an explosion or fire from a spark can result if the electrical circuit breakers are
accidentally turned on while you are installing or servicing this product. Refer to this manual (and
documentation for related equipment) for complete installation and safety information.
WARNING: Before you enter a containment sump, check for the presence of hydrocarbon
vapors. Inhaling these vapors can make you dizzy or unconscious, and if ignited, they can explode
and cause serious injury or death. Containment sumps are designed to trap hazardous liquid
spills and prevent environmental contamination, so they can accumulate dangerous amounts
of hydrocarbon vapors. Check the atmosphere in the sump regularly while you are working in
it. If vapors reach unsafe levels, exit the sump and ventilate it with fresh air before you resume
working. Always have another person standing by for assistance.
WARNING: Follow all federal, state, and local laws governing the installation of this product
and its associated systems. When no other regulations apply, follow NFPA codes 30, 30A, and 70
from the National Fire Protection Association. Failure to follow these codes could result in severe
injury, death, serious property damage, and/or environmental contamination.
WARNING: Always secure the work area from moving vehicles. The equipment in this manual
is usually mounted underground, so reduced visibility puts service personnel working on it in
danger from moving vehicles that enter the work area. To help prevent this safety hazard, secure
the area by using a service truck (or some other vehicle) to block access to the work area.
WARNING: Discharge static electricity from the splice kit to ground before you install it, and
make sure it is properly grounded while in service.
WARNING: Make sure you check the installation location for potential ignition sources such as
radio waves, ionizing radiation, and ultrasound sonic waves. If you identify any potential ignition
sources, you must make sure safety measure are implemented.
WARNING: Always disconnect both power supplies (110-250V Hook and the 208-240V input)
before installing or servicing. Failure to do so could result in severe injury or death.

NOTE TO STATION OWNER: Save these instructions for future use, and make sure you provide
them to anyone who services this equipment.
NOTE: Wiring diagrams are in the "Troubleshooting" chapter of this manual.
1. Install the STP according to its installation documentation.
IMPORTANT: The unit can be damaged if you turn on the power when the motor leads are
shorted together or to ground.
2. Use an ohmmeter to verify that the motor leads (M1 and M2) are not shorted to ground.
3. Remove the STP-SCI cover, and install the base on a wall or other flat surface.
3
NOTE: You must install the STP-SCI indoors. It can operate at an ambient temperature of
400 – 1050 F (40 – 410 C).
4. Connect the 208-240 VAC input power to L1 and L2, and connect the ground wire to the
terminals as shown in the "STP-SCI Stand Alone wiring diagram." Do not apply input power
until you are instructed to do so.
5. Connect the motor leads to M1 and M2, and connect the ground wire to the terminals as
shown in the "STP-SCI Stand Alone wiring diagram."
6. Connect the Dispenser Hook Signal to the terminals, 110-250 VAC Supply, and Return
according to the "STP-SCI Stand Alone wiring diagram" or "STP-SCI Master-Slave wiring
diagram" (whichever is appropriate). The hook signal can come from a dispenser, isolation
relay, or STP-DHI. For more information, refer to the "STP-DHI Installation and Owner's
Manual" (part number 223844101).
7. If you are setting the controller to the stand alone configuration, set SW1 and SW2 poles 1-8
according to the "STP-SCI Stand Alone wiring diagram." (The stand alone configuration is the
default factory setting.) For Master-Slave and/or Alternating Circuit (AC) configurations, please
see the "STP-SCI Master-Slave wiring diagram."
Master-Slave/Alternating Circuit
The Master-Slave feature (see the "STP-SCI Master-Slave wiring diagram") allows you to turn on
additional STPs when an STP needs help due to loading (flow rate) or an abnormal condition exists.
The AC feature (see the "STP-SCI Alternating Circuit wiring diagram") continuously alternates the
lead pump, so it turns on a different STP each time all dispensers are shut off and at least one
dispenser is turned back on. The Master-Slave/AC configuration (see the "STP-SCI Master-Slave/
Alternating Circuit wiring diagram") combines the features of Master-Slave and AC.
CAUTION: Line leak detection performance can be affected when you use multiple STP-SCIs. FFS
does not recommend using the AC feature in conjunction with electronic line leak detection. Some
electronic line leak detector manufacturers require the master to always be turned on first. Please
refer to the manufacturer’s requirements.
NOTE: STP-SCI is not compatible with the STP-SC or STP-SCB in Master-Slave or AC configurations.
NOTE: Master-Slave does not work with PMA33, PMA75B (50 Hz PMA), or PMAH150B (50 Hz PMA).
NOTE: In software revision 1.4 and prior, the AC configuration functions the same as a
Master-Slave/AC configuration.
NOTE: Wiring diagrams are in the "Wiring Diagrams" section of the "Troubleshooting" chapter.
1. Connect the communication cable, RS 485, to terminals (+, G, and –) wire “+” together, “G”
together and “-“ together then wire the shielded cable drain wire to Ground (G) at one end
only, Use at least 22 AWG three conductor shielded cable with drain wire.
2. Make sure the Dispenser Hook Signal is connected to the STP-SCI designated as master
according to the "STP-SCI Master-Slave wiring diagram" the "STP-SCI Alternating Circuit wiring
diagram" and the "STP-SCI Master-Slave/Alternating Circuit wiring diagram." The hook signal
can come from a dispenser, isolation relay, or STP-DHI. For more information, refer to the "STPDHI Installation and Owner's Manual" (part number 223844101).
4
NOTE: Make sure L1, L2, M1, M2 and grounds are installed at each STP-SCI.
3. Configure Master-Slave and AC features by setting SW2 poles 3 and 4 according to the
"Switch definitions" table.
4. Create a unique address for each controller by setting SW1, poles 1-5 according to the
following table. Each controller must have its own unique address.

Selectable features
Auto Restart Mode (SW1, Pole 8)
When this mode is selected, with the switch in the ON position, if the controller detects an
empty tank/under load condition, it shuts down the pump and it attempts to start the pump
when a hook signal is removed and reintroduced to the controller. If the empty tank condition is
6
still present, the controller shuts down the pump. If the empty tank condition is corrected (i.e.,
the tank is refilled), the controller runs the STP and clears the abnormal condition. In MasterSlave configuration, if the master is in the under load condition, it waits until the slave controller
calls for help before attempting to restart.
Fault Shutdown Mode (SW2, Pole 1)
This is for only Master-Slave and AC configurations. This mode needs to be selected only on the
master controller. When you select this mode, with the switch in the ON position, the entire
system shuts down if any of the controllers, master or slave, detect an abnormal condition. The
system does not run until the abnormal condition is corrected and you push the reset button, or
you turn off the fault shutdown mode switch and push the reset button. The fault shutdown is
required if you are using a Veeder-Root™ PLLD in a Master-Slave configuration.
Extended Run Disable (SW2, Pole 5)
This switch, in the ON position, disables the extended run fault detection of the STP-SCI. The
extended run fault shuts off the STP if it has been running for 60 minutes without a change in
product flow. You might, for example, use this switch with an emergency generator where the
STP runs at all times.
CAUTION: Do not disable the extended run if the system requires the pump to be off for line
leak detection (i.e. mechanical leak detectors or electronic line leak detection). Disabling the
extended run fault and running the STP continuously could mask a leak in the system.
Calibration
NOTE:
• All three indicator lights flash alternately during calibration.
• The STP-SCI calibrates only when the STP has no abnormalities and a dispenser handle is
turned on within 10 minutes of calibration starting.
• If you have a blending dispenser system, you can select the mid-grade handle at the
dispenser to calibrate all blended product STP-SCIs simultaneously.
• If the controller loses power, it retains the calibration data.
IMPORTANT:
• You must calibrate all STP-SCIs before you operate them.
• Make sure there is no flow during calibration, otherwise there may be false abnormal
conditions.
• If you use electronic line leak detection, make sure the STP-SCI is in calibration mode before
you turn on the dispenser handle. If the controller is not in calibration mode, the line leak
detector senses a fault and does not provide a dispenser hook signal to the STP-SCI. This
prevents the STP-SCI from calibrating until you reset the line leak detector.
• Make sure the fuel level in the tank is above the motor intake before you start calibration.
7
Calibration steps
1. Close either the STP clamp valve or a ball valve at the STP discharge, attach the cover of
the controller to the base, and then turn on the power supply to the STP-SCI. The green
indicator lights without flashing, the red indicator flashes eight times, and the audible alarm
beeps eight times. This indicates the STP-SCI is not calibrated.
2. Press and hold the reset button until all three indicators blink alternately. This puts the
controller in calibration mode. After approximately 10 seconds, release the reset button. For
Master-Slave and AC configurations, put the master and all the slaves into calibration mode
before you proceed to the next step.
3. Lift a handle on a dispenser to turn the pump on. After approximately 16 seconds, the
controller records the voltage, current, and power. With the exception of the green light,
the indicators stop flashing. This indicates the calibration is complete. Turn off the dispenser
handle, and open the STP clamp valve or ball valve. If the controller does not calibrate, the
red light flashes, and the audible alarm beeps to indicate an abnormal condition code. See
the “Troubleshooting” chapter to identify and correct this condition.
8
Troubleshooting
The STP-SCI has a microprocessor that allows the unit to diagnose abnormal conditions and
communicate them through an audible alarm and LEDs on the front panel. The following
describes these indications:
• When the green indicator is lit, power (208-240V) to the STP-SCI is turned on.
• If the green indicator is flashing, the pump motor assembly (PMA) is running.
NOTE: If the green indicator is lit (without flashing), even when a dispenser is activated,
check the dispenser hook signal terminals on the STP-SCI. If 110–250 VAC is across the hook
terminal, and the switch settings are correct, contact FFS Technical Support for assistance.
CAUTION: If the green light flashes, even when all the dispensers are turned off, there
may still be power present at the STP-SCI hook terminal. If this is the case, contact FFS
Technical Support for assistance.
• If the red indicator is flashing or the audible alarm is beeping, there is an abnormal
condition. Note the number of flashes or beeps, and refer to the appropriate
troubleshooting topic.
Disabling the audible alarm
Press the reset button briefly to silence the audible alarm without resetting the controller.
Reset
Before you correct an abnormal condition (red light flashing/alarm beeping), do the following:
1. Note the number of flashes and beeps.
2. Reset the controller by pressing the button on the side of the control box for three to ten
seconds.
3. Release the button when all three indicator lights go out.
4. Check for proper operation.
5. If the controller operates correctly, stop servicing the unit.
-orIf the abnormal condition continues, correct the condition according to the troubleshooting
guide. Reset the controller, and then check for proper operation. Contact FFS Technical
Support for assistance, if needed.
9
Selectable features to aid troubleshooting
Fault Read Out Mode (SW1, Pole 6)
To enable this mode, turn off power to the STP-SCI, and remove the console cover. Turn ON SW1
pole 6, reinstall the cover, and then turn on power to the STP-SCI to see the fault readout. In this
mode, the controller displays the last 5 abnormal conditions. The controller beeps once, and the
red LED flashes the most recent abnormal condition. It then beeps twice, and the red LED flashes
the next-to-last abnormal condition. The controller follows this sequence through 5 beeps and
then repeats this pattern while in this mode. If there are less than 5 abnormal conditions, the
controller still beeps but the red LED does not flash.
Bypass Mode (SW1, Pole 7)
When this mode selected, with the switch in the ON position, the controller operates as a
standard relay control box. It will not indicate or shut down due to an abnormal condition,
with the exception of an over current condition. The bypass mode is active for a maximum 10
minutes, after which, the controller reverts to its normal operation. Push the reset button to
allow the controller to run in bypass mode for another 10 minutes.
