NEXUS PPC6000 SERIES FUEL AIR RATIO CONTROLER Bulletin PPC-6001
The Fireye NEXUS PPC6000 is a state of the art stand-alone parallel position system
for all types of liquid or gaseous fuel fired combustion systems. When combined
with a Fireye flame safeguard system such as the Fireye BurnerLogix control, the
PPC6000 offers the most compact and advanced parallel positioning system avail-
able. Four fuel profiles allow the PPC6000 to accommodate a variety of applications
such as two fuels, with and without, the optional variable speed drive (VSD). With
each profile having up to 24 points entered to assure a smooth "curve", the micro-
processor interpolates points between entered values and precisely positions fuel
and air to within +- .1 degree. This eliminates hysteresis for improved efficiency.
The PPC6000 is capable of powering up to ten 24 volt servomotors supplied from
the integral transformer. All servomotors and displays operate on a secure CANbus
communications protocol and can be "daisy chained" together for simplified wiring.
Two independent PID control loops for temperature or pressure control provide
precise, accurate control of firing rate for unmatched response to load changes. Four safety rated user definable digital inputs are standard
and can be configured for functions such as lead lag, night setback, thermal shock warm up, etc. Digital inputs can also be configured as
analog inputs via the optional programmable function blocks using Fireye Abacus software. Built in lead lag sequencing for up to four boilers
is included in every PPC6000. More elaborate lead lag schemes may be possible using the programmable function blocks.
Two variations of multifunction vacuum florescent displays are available:
NX600 standard display provides programming, status, and fault information.
NX610 display provides automatic storage of operating parameters and profiles for upload/download to the PPC6000.
In addition, three line voltage fully programmable relays are mounted inside the display.
Other options include, two Variable speed drive (VSD) outputs via daughter board, Oxygen Trim - using Fireye's proven heated zirconia oxide
probe and optional interface, a wide variety of communications platforms such as Modbus are also available.
An optional internal freely programmable logic section of the PPC6000 means that external PLC's and expensive stand-alone sequencing
controls may no longer be needed. Easy to program and protect, this new feature will make the PPC6000 suitable for many unique or
unusual applications. Functions such as lead lag, sequencing, feedwater control and draft control are just some of the ways this feature can
be used.
Optional ComFire software allows the user to view and control all aspects of the burner system, provides real time trending and logging,
upload and download of profiles and options. The user can build custom screens or import actual photographs of the combustion equip-
ment for animation.
