Use of Programmed Inputs -
TPI and Relays
The following illustrations will help understand how the programming of each method can create
a positive shutdown given a programmed input under the submersible turbine programming of
either turbine pump interface or relay.
Turbine Pump Interface (TPI)
Turbine Pump Interface (TPI) is a communication protocol and parameter programming subset
that allows the EVO™ series console to control several FE Petro™ intelligent pump control relays.
The primary function of TPI is to monitor and manage FE Petro pump controllers. The FE Petro
pump controllers are connected to the EVO™ series console via a three conductor shielded cable.
This cable is daisy-chained between each controller. The wires connect to three terminals; a
positive (+), a negative (–) and a ground (gnd). The wiring is then daisy-chained like color to like
color to all pump controllers to the corresponding terminals (+ – gnd).
On the EVO™ Series Console, the TPI port has 5 total spaces. The first two terminals (A and B) are
not used for TPI applications.
For EcoVFCs and MagVFCs that are functioning in a group scenario (Leveling, Priority, None) the
#4 (Frequency) terminal should be connected between the two VFCs. This allows for frequency
data to be transferred.
Each controller is then given a specific address that the console uses to recognize that individual
controller. The EVO™ console can be configured for a maximum of 31 controllers with any
variation of controllers being accepted. The controllers themselves may have restrictions with
how many can be configured due to dip switch limitations. Within the TPI relationship the
EVO™ console always acts as a Primary controller and all subsequent controllers are considered
secondary devices. Being the Primary Controller means that the EVO™ console is internally
addressed as 0 and cannot be changed, therefore the controllers should be addressed starting at
1 as a secondary device.
