4.4 P3 PULSE Electronic Control System
4.4.1 Overview
The Wallenstein P3 PULSE Electronic Control System optimizes
the capacity of the chipper. Operators can adjust feed settings
to customize chip size when chipping any type of material. P3
tracks rotor hours of operation and provides system diagnostics.
In the unlikely event the rotor becomes jammed with material,
P3 quickly stops the engine to prevent clutch burn out.
P3 keeps the chipper working in the peak working range by
matching feed rate with rotor speed. As material is put into the
chipper, a sensor on the rotor sheave continually monitors rotor
rpm. If the rotor slows down under load, P3 slows the feed
roller speed allowing the rotor to recover. If it slows below the
minimum rotor speed setting, P3 auto-reverses the feed rollers
preventing a stall out. Wood material is then pulled away from
the rotor giving it the opportunity to regain speed. Once back
at operating rpm, the feed rollers start feeding material into the
chipper again.
P3 PULSE consists of a rugged, user-friendly 4.3" (109 mm)
display and electronic controller. From the display, the user can
see all the important operating parameters. These parameters
are set up depending on machine model.
Navigating through the menus is done with the four soft keys
below the display screen. Icons in the display above the soft
keys indicate menu selection options.
IMPORTANT! Graphical display and controller are not
serviceable. Return to the factory in the event of failure.
