PPC4000 Parallel Positioning System

Four fuel profiles allow the PPC4000 to accommodate a variety of applications such as two fuels, with and without, the optional variable frequency/speed drive (VFD/VSD). With each profile having up to 24 points entered to assure a smooth “curve”, the microprocessors within the PPC4000 interpolate points between entered values and precisely position fuel and air servos to within ± 0.1 degree, and the VFD to within 0.1% of its full scale range. The result is improved efficiency by eliminating hysteresis typically found in slide wire or single point positioning systems.

Additional gains in burner efficiency can be realized by adding the optional (VFD/VSD) drive board and Fireye O2 probe. The PPC4000 is capable of controlling a total of ten servo motors, four servos per profile. All servo motors and displays operate on a secure communications protocol and can be “daisy chained” / multi-dropped together for simplified wiring. Available servos from Fireye have torque ranges of 4 Nm (3 ft./lb.), 20 Nm (15 ft./lb.), and 50 Nm (37 ft./lb.). Two independent PID control loops for temperature or pressure control provide precise, accurate control of firing rate for unmatched response to load changes.

Ten safety rated user definable line voltage inputs are standard and can be configured for functions such as burner on, setpoint select, lead lag, setback, etc. The PPC4000 also contains programmable relays that can be used for various functions throughout the burner sequence. Built in lead lag sequencing for up to four boilers is included in every PPC4000. The PPC4000 contains an SD (Secure Digital) card interface that provides data logging of a burner’s operation at user defined intervals as well as upload/down- load capability.
