XPro Series
Bulk Tank Pressure Transmitter
The system controller requires the pressure input of the
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 XPro 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
Electrical Power Supply
provided to power the Trifecta XPro Series control system. If
may be necessary.
The Mitsubishi PLC is mounted within a NEMA 4 control
box as shown in the following photograph.
It is important that care is taken to install the Trifecta XPro
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
be recognized that a PLC (computer) controls the Trifecta
to power the Trifecta XPro Series system. Connecting the
Trifecta to a circuit that is backed up by a generator might
also be advantageous.
Commissioning
commissioning the Trifecta.
Warning! It is important to purge the
entire Trifecta XPro 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.
Note: On early versions of the 600 psig high
valves.
Purge and Pre-Charge of the Trifecta XPro
Series (Ref. to Fig. 2, Pg. 19 for valve tags)
purge the complete system using low-pressure nitrogen.
• Close the use valve (V-2)
• Open the liquid valve on the bulk tank and let the bulk
tank equalize with the two trifecta tanks.
•
liquid valve on the bulk tank.
• Let lines thaw.
• Leak check all plumbing connections.
