5. Connect the motor leads to M1 and M2, and connect the ground wire to the terminals as
shown in the "SPGC-220 Stand Alone wiring diagram."
6. Connect the Dispenser Hook Signal to the terminals, 120-240 VAC Supply, and Return
according to the "SPGC-220 Stand Alone wiring diagram" or "SPGC-220 Primary-Secondary
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, make sure the SW1 and
SW2 poles 1-8 are set according to the "SPGC-220 Stand Alone wiring diagram." (The Stand
Alone configuration is the factory default setting.) For Primary-Secondary or Alternating
Circuit (AC) configurations, please see the "SPGC-220 Primary-Secondary/Alternating Circuit
wiring diagram."
Primary-Secondary/Alternating Circuit
The Primary-Secondary feature (see the "SPGC-220 Primary-Secondary wiring diagram") allows
you to turn on additional STPs when there is an abnormal condition or an STP needs help due
to loading (flow rate). The AC feature (see the "SPGC-220 Alternating Circuit wiring diagram")
continuously alternates the lead pump, so it turns on a different STP each time all dispenser hook
signals are shut off and at least one dispenser hook signal turns back on. The Primary-Secondary/
AC configuration (see the "SPGC-220 Primary-Secondary/Alternating Circuit wiring diagram")
combines the features of Primary-Secondary and AC.
CAUTION : Line leak detection performance can be affected when you use multiple
SPGC-220s. FFS does not recommend using the AC feature in conjunction with electronic line
leak detection. Some electronic line leak detector manufacturers require the Primary to always
be turned on first. Please refer to the manufacturer’s requirements.
NOTE:
The SPGC-220 is compatible with the STP-SCI in Primary-Secondary or AC configurations.
NOTE: Wiring diagrams are in the "Wiring Diagrams" section of the "Troubleshooting" chapter.
1. Connect the communication cable to the RS 485 terminals (+/A, G/GND, -/B) 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 SPGC-220 designated as Primary
according to the "SPGC-220 Primary-Secondary wiring diagram" the "SPGC-220 Alternating
Circuit wiring diagram" and the "SPGC-220 Primary-Secondary/Alternating Circuit wiring
diagram." 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).
NOTE: Make sure L1, L2, M1, M2 and grounds are installed at each SPGC-220.
3. Configure Primary-Secondary and AC features by setting SW2 poles 3 and 4 according to the
"Switch definitions" table.
