Leak Check
to plumbing stack on tank and all connections to pressure
transmitters.
• A leak at any point in the Trifecta XPro Series system
will result in loss of product.
• A leak in the plumbing within the plumbing stack or
pressure transducers and transmitters can cause incorrect
values to be translated by the PLC. These transducers
which tell it when to open and close solenoids. Incorrect
values will cause the Trifecta unit to operate in a random
fashion and could cause supply issues downstream.
Data from Main Screen and Analog
Pressure Gauges
Record Trifecta XPro Series and bulk tank parameters as
described in the Parameter Settings section of this manual.
Compare these values to those on the analog gauges of the
tanks and the bulk tank. (an example form is on the next
page.)
