Important Safety Messages
Franklin Fueling Systems equipment is designed to be used to pump volale hydrocarbon liquids such as
gasoline and diesel fuel. Installing or working on this equipment means working in an environment in which
these highly ammable liquids are present. This presents a risk of severe injury or death if these instrucons
and standard industry pracces are not followed. Read and follow this enre instrucon booklet before
installing or working on this equipment.
As you read these instrucons, watch for the following safety symbols:
WARNING This symbol idenes a potenally hazardous situaon which, if the instrucons that follow
it are not adhered to, could result in death or serious bodily injury.
CAUTION This symbol idenes a potenally hazardous situaon which, if the instrucons that
follow it are not adhered to, could result in serious property damage, including possible
environmental contaminaon as a result of the leakage of fuel from the equipment.
WARNING Follow all federal, state, and local laws governing the installaon of this product and its
associated systems. When no other regulaons apply, follow NFPA codes 30, 30A, and 70
from the Naonal Fire Protecon Associaon. Failure to follow these codes could result in
severe injury, death, serious property damage and/or environmental contaminaon.
WARNING Always disconnect both power supplies (240V Hook and the 415 input) before installing or
servicing. Be sure to use proper lock and tag out techniques to ensure no power is applied
accidentally. Failure to do so could result in severe injury or death.
Installer: This instrucon booklet MUST be le with the owner of the service staon at which the equipment is
being installed.
Staon Owner: Retain these instrucons for future use and provide them to persons servicing or removing this
equipment.

STP-SCIIIC: For 240 Volt hook signal; 380-415 Volt, 3 phase, 50Hz ¾ , 1 ½ , 3 and 5 Horsepower pumps.
Installation Instructions
1. Install STP per applicable Installaon and Owner’s Manual.
2. Remove cover of STP-SCIIIC and mount base to wall or other surface.
3. Connect input power of 380-415V for STP-SCIIIC to L1, L2, L3 and Ground wire to terminals.
(See Figure 2.) On High Capacity Pumps (3HP & 5HP) there is no need to connect the Thermal Overload
wires (blue) coming from the pump as long as an STP-SCIIIC is being used and is calibrated properly.
4. Connect dispenser hook signal or other equipment to terminals, 240V supply and return for STP-SCIIIC.
5. Using an ohmmeter, conrm M1, M2 & M3 have connuity to pump. Also, make sure M1 to Ground, M2 to
Ground, and M3 to Ground are not shorted.
6. Connect motor leads to M1, M2 and M3, and Ground wire to terminals.
7. Set SW1 Poles 4 and 5 for the motor Horsepower rang (see Table 3).
8. For Stand Alone installaon, set (SW1) poles 1-3 per Table 2 (Factory Set). If installed as Master-Slave and/
or Alternang Circuit go to “Master-Slave/Alternang Circuit” secon.
9. Aach cover of controller to base. Then go to “Calibraon” secon to complete installaon.
WARNING Always replace the cover of the STP-SCIIIC before applying power. Failure to do so could
result in severe injury or death.
Calibration
Note: It is recommended to calibrate all manifolded Master and Slave controllers at the same me.
1. Turn on power supply to the STP-SCIIIC. The green light indicator will come on steady, the red light
indicator will ash 8 mes and an audible alarm will sound, thus indicang the controller is Uncalibrated.
Note: The audible alarm will sound each me the red light indicator ashes. During the calibraon process,
do not silence the alarm. Once the calibraon process has been completed, an alarm can be silenced when an
abnormal condion is present by briey depressing the push buon. See “Troubleshoong Guide” for details.
2. Press and hold the push buon on the boom of the box unl all three light indicators blink alternately.
This will take approximately 10 seconds. At this point the push-buon should be released.
3. The handle on the dispenser should then be lied to turn the pump on (for more than 16 seconds). Aer
16 seconds the controller will take a “snapshot” of the voltage, current and power. The three lights will
quit alternang and only the green light should remain ashing. This will indicate the calibraon has been
completed and the dispenser handle can then be turned o. If the controller(s) will not calibrate, see the
“Troubleshoong Guide” secon.
Calibration Tips
The “snapshot” values will be used as the nominal values. The calibraon process will be aborted if not
completed within 10 minutes or if the push buon is depressed during calibraon. The calibraon must be
done at zero ow. If an electronic line leak detector is being used, it is important that the STP-SCIIIC be in the
calibraon mode (all three lights ashing alternately) before the dispenser handle is turned on. Otherwise, the
STP-SCIIIC will not turn on and the line leak detector will likely detect a fault. If the line leak detector shows a
fault, it will not provide a dispenser hook signal to the STP-SCIIIC and it will not be possible to calibrate the STP-
SCIIIC unl the line leak detector is reset.
Note: All STP-SCIIICs must be calibrated prior to operaon.
Note: All three indicator lights will ash alternately in calibraon mode.
Note: When calibrang system and dispensers that are blenders, both STP-SCIIICs must be calibrated
simultaneously by selecng the mid-grade at the dispenser.
Note: The calibraon data is retained in non-volale memory (i.e. it is saved in the event of power loss to the
controller).

Master-Slave/Alternating Circuit
Note: RS 485 Connecon is only required if Master-Slave or Alternang Circuit operaon is desired.
Note: Be sure L1, L2, L3; M1, M2, M3 and Grounds are installed at each STP-SCIIIC.
The Master-Slave feature allows the master to turn on addional STP’s when the rst STP operang needs help
due to loading (ow rate) or an abnormal condion exists. The Alternang Circuit (AC) feature connuously
alternates the lead pump, thus turning on a dierent STP each me all dispensers are shut o and at least one
dispenser is turned back on.
1. (Fig. 2) Connect RS 485 (+, G, & –) to terminals. Connect drain wire of shielded cable to Ground (G) at
one end only. Wire per NFPA 30A and NFPA 70. For the signal wires, use 18 AWG 3 conductor cable (300V
min.), with conductors twisted and within a common jacket. Cut wires to length so that there is no excess
wire touching circuit board components.
2. (Fig. 2) Connect hook between STP-SCIIIC’s.
3. Set Master-Slave and Alternang Circuit features on (SW1) poles 1-3 per Table 2.
4. Set (SW1) poles 7-8 per “Table 1”. The address must be set for each STP-SCIIIC.
5. Aach cover of controller to base. Then go to “Calibraon” secon to complete installaon.
WARNING Always replace the cover of the STP-SCIIIC before applying power. Failure to do so could
result in severe injury or death.
Note: There can only be one Master in a system and up to 3 slaves.
