OPERATION
4.5 SAFETY bAR (EuRo moDELS)
The lOFA control connects to the shaft sensor and solenoid
coil. The sensor (Figure 4.3) should be positioned 1/32"
from the rotor collar bolt. The solenoid coil is attached to
the crossover relief valve (Figure 4.4).
When the system senses that the rotor RPM has dropped
below a certain preset level, it will slow the hydraulic feed.
When the rotor RPM returns to a normal operating level,
the hydraulic feed will return to its previous rate.
