Bulk Tank Pressure Transmitter
The system controller requires the pressure input of the
bulk tank to perform the filling procedure as efficiently as
possible This is done through a pressure transmitter The
pressure transmitter measures the pressure of the bulk tank
and sends an electrical signal back to the controller The
transmitter for the bulk tank is located in the upper piping of
the Trifecta Pro Series and pre-wired into the control box No
additional piping is required by the customer to receive the
bulk tank pressure; this will automatically read the current
bulk tank pressure, unlike previous models.
Electrical Power Supply
A dedicated 120 volt AC, 60 Hz, 15 amp circuit must be
provided to power the Trifecta Pro Series control system If
120 VAC is not available, an appropriately sized transformer
may be necessary
The Allen Bradley PLC is mounted within a NEMA 4 control
box as shown in the following photograph (Fig 2)

It is important that care is taken to install the Trifecta Pro
Series system on a dedicated electrical power circuit that is
clean and protected Circuits that are susceptible to noise and
brownouts may cause erratic system behavior Care should
also be taken to avoid installation on a circuit that regularly
gets turned on and off to provide power to another piece of
equipment (lights, heaters, cooling systems etc.). It should
be recognized that a PLC (computer) controls the Trifecta
Pro Series system and a clean, steady circuit must be used
to power the Trifecta Pro Series system Connecting the
Trifecta to a circuit that is backed up by a generator might
also be advantageous
Commissioning
The following procedures should be followed when first
commissioning the Trifecta
Warning! It is important to purge the
entire Trifecta Pro Series and
piping with warm, dry nitrogen
before running the system with
liquid. Water vapor can cause
ice crystals to form that may
cause the solenoid valves and
other critical components to
operate improperly.
