18. Electrical System:
The chipper is designed with an electri-
cal system that includes a CPU (Central
Processing Unit), display, speed sensor
and electro-hydraulic valve. The CPU
measures the rotor speed through the
speed sensor and closes the valve when
the rotor speed slows. It also increases the
ow when the rotor speed recovers back to
operating RPM.
