Stand Alone Pump Operation

The VSFC Controller's microprocessors are preprogrammed from the factory for stand alone operation, i.e., one
VSFC Controller and one VSFC STP pressurize the product line.

Tandem Pump Operation

When multiple VSFC STPs are required to maintain proper flow, their VSFC Controllers can be programmed to
operate in tandem. The master VSFC Controller varies the speed of the primary pump depending on the pressure
in the line. When the primary pump can no longer maintain proper pressure, additional pump(s) come on line to
supplement the pressure and maintain proper flow. Instructions in the VSFC Installation Guide (P/N 577013-815)
explain how to setup for tandem operation.
Master-Slave Operation
The installer can designate one VSFC Controller as the master unit and the others as the slave units. The master
VSFC Controller monitors line pressure and determines when a supplemental pump is required. Additional pumps
will turn on if they have received a dispense-enable signal.
Alternating Operation
This feature allows the pumps to alternate and prevent the problem of having one tank run dry. It also ensures that
one pump does not wear excessively. For each dispensing cycle, the master VSFC Controller determines which
VSFC STP will be the primary pump. When the master controller receives the dispense-enable signal, the primary
pump starts. The master VSFC Controller monitors line pressure and determines when a supplemental pump is
required. Additional pumps will turn on even if they have not received a dispense-enable signal.
Tank-Based Operation
Individual pumps will turn on when they have received a dispense-enable signal. The master VSFC Controller
monitors line pressure and determines when a supplemental pump is required. Additional pumps will turn on even
if they have not received a dispense-enable signal.
NOTICE
IMPORTANT!
For VSFC stand alone installations a V-R PLLD Pressure Transducer is required in the VSFC STP. To
install this transducer, refer to the relevant section of the PLLD Site Prep guide (P/N 576013-902).
For VSFC Tandem, Master-Slave, Alternating, or Tank-based installations, a V-R PLLD Pressure
Transducer is required only in the VSFC STP that is connected to the Master VSFC Controller. To
install this transducer, refer to the relevant section of the PLLD Site Prep guide (P/N 576013-902).
For VSFC installations in sites that have a TLS-350 Console with PLLD line leak detection monitoring
the product line, a separate PLLD transducer is not required because the VSFC unit and the PLLD
system will share the same transducer that is installed in the VSFC STP.
For all VSFC STP installations you must make wiring connections in the pump (i.e., pressure
transducer, I.S. Barrier, and pump power connections) following the instructions in the VSFC
Installation Guide (P/N 577013-815).
