HOIST ROTATION INDICATORS (HRI)
The Hoist Rotation Indicators for the auxiliary and main hoist
is located on top of each hoist control lever (1,4, Figure 3-9).
Each indicator is electronically driven by an input signal from
a sensor attached to its related hoist and an output signal
from a control module. Each hoist control lever (1,4) pulses
when its hoist is running so the operator’s thumb can sense
it.

Figure 3-10. The LED display illuminates to indicate the
current hoist in operation and which direction the hoist is
rotating.
