Wiring and Programming of the TPI (Turbine Pump Interface) with an FEPetro SCIII (3-Phase Smart Controller)
Overview
The STP-SCIII 3-Phase Smart Controller can be controlled by the INCON TPI via an RS-485 connection.
The TPI can be used to:
• Mimic a syphon system and manage manifolded pumps thru Leveling Mode
• Manage manifolded pumps thru Priority Mode
• Manage the use of the pumps thru Master / Slave mode
• Manage the use of the pumps when alarms occur
110 VAC must be supplied to the hook for the relay to close. The communication signal supplied by the TPI is not enough to
engage the relay. Therefore a Relay module is needed to control a separate 110 VAC source for the hook signals. The AC
Inputs from the dispensers are wired to the TS-ACI AC Input module in the tank gauge and then programmed as inputs to
both the TPI and to the Normally Open Relay. This will allow both the TPI and the Relay to activate at the same time. The
hook signal needs to go to the TS-ACI module in the tank gauge.
The STP-SCIII switches should be set as Slave (Dip Switch 1 off). The T5 programming should be set as Master / Slave.
Doing so will prevent the motor from running continuously when communication is lost to the TPI.
The relay is wired as Normally Open and programmed as inverted. The STP will turn off if the gauge loses power.
