TS-TPI Overview and Functionality
Tank fuel management can be achieved using a Franklin
Fueling Systems T5 Series Fuel Management Systems
and an FE Petro Turbine Pump Controllers (STP-SC1,
EcoVFC or MagVFC). 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.
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 T5 series 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 BLOCKED 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.
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.
