TS-TPI Overview and Functionality
Tank fuel management can be achieved using a Franklin
Fueling Systems TS-550 evo Series Fuel Management
Systems and an FE Petro Turbine Pump Controller (STP-
SCI, SCIII, EcoVFC or MagVFC) through Turbine Pump
Interface (TPI). Refer to Bulletin TB1010-04 for connecting
to an STP-SCIII controller.
Tank Fuel Management looks at percent (%) full volume of
individual tanks and gives priority to the submersible pump
needed to control tank inventories. Additional features and
benefits of the Tank Fuel Management system include:
• Tank Overfill Protection
• Dry Tank Indication
• Automatic pump controller reset
• Clogged Intake Indication
• Pump in Water Indication.
• Use of additional pumps in the same group when de-
mand increases
Tank Fuel Management can be used to keep tank levels
similar, eliminating the need for a syphon system. Tank Fuel
Management can also be used to pump down one tank to a
user defined level, and then switch over to the other tank for
fuel dispensing. In either case, there must be at least one
submersible pump in each tank.
TS-TPI Overview
The TS-TPI programming function allows the controllers
to be “grouped” together, and be programmed for specific
fuel management options. These options are NONE,
LEVELING, and PRIORITY
• NONE means NO level management for the selected
pump group. (Default setting.)
• LEVELING mode seeks to maintain an equal level of
fuel in each tank by placing pump controllers associated
with the tank containing the most amount of fuel to
priority. This will force the pump installed in the tank
with the highest level of fuel to activate with the next
activation of a dispenser switch.
Note: Leveling is achieved using level as percentage
volume full. The tank gauge will look at levels in a
tank as % full, and will attempt to keep that number
equal between all tanks in LEVELING mode. If
tanks are different sizes, the levels in tanks may not
be equal, but the % full for each tank will be similar.
• PRIORITY mode tries to pump down one tank before
switching to other tank(s). After choosing PRIORITY
mode, the technician will program the RESERVE
setting. The reserve level is input as a percent full in
the tank. When the RESERVE level is reached for that
tank, priority will switch to the pump in the other tank.
If both tanks are below RESERVE level the ATG will
automatically use Leveling until tanks receive a delivery
of fuel or reach Dry Tank Indication Levels.
Note: In both Leveling and Priority modes, the ATG
chooses which pump will take priority. Because of
this, the pump controllers should be set to Master-
Slave, not Master-Slave / Alternating Circuit. If
the pump controllers are configured for Master-
Slave / Alternating Circuit, the pumps will not turn on
in a predicable manner. Tanks that are in Leveling
or Priority mode are monitored and tested as
separate tanks and should NOT be siphoned.
Other TS-TPI functions include;
Overfill Protection: when the LEVELING and PRIORITY
modes are chosen, if a tank level rises above its high level
limit, that tank will become the priority tank, regardless
of what leveling mode is active. If the level in that tank
continues to rise and reaches the high-high limit, all pumps
in the group will be shutdown, except for the pump in the
tank with the high-high alarm. In-line check valves used
to prevent overfill conditions in manifolded tanks, such as
those used with Red Jacket submersible pumps, are not
required or recommended.
Note: The Overfill Protection feature will work correctly
ONLY when the high and high-high level alarms
are programmed correctly. Failure to set high and
high-high level alarms will result in a loss of overfill
protection.
Dry Tank Indication: TS-TPI programming enables the
user to enter a PUMP HEIGHT measurement (default is
5”). This is the distance between the bottom of the pump
motor to the bottom of the tank. When the pump controller
indicates an Under - Load condition and the product level is
within 3” of the programmed PUMP HEIGHT measurement,
an alarm on the tank gauge will indicate DRY TANK. When
a delivery is made, the pump controller will automatically be
reset.
Note: Because the TS-TPI resets the pump controller
after a delivery is made, the Auto Restart feature on
the pump controller must be disabled.
Clogged Intake Indication: The combination of a pump
controller Under-load condition and a tank level that is
at least 3” greater than the programmed PUMP HEIGHT
measurement will cause a CLOGGED INTAKE indication.
Because the tank gauge is able to confirm that there is fuel
in the tank, this alarm indicates a motor intake that is being
blocked by a foreign object. Hence the pump stops and start
for 3 times to try to remove the foreign object.
Pump in Water Indication: If the tank gauge records
a water level that is within 2” of the programmed PUMP
HEIGHT measurement, the pump will become disabled. The
tank gauge will indicate a PUMP IN WATER alarm.
