CONTROL PENDANT ASSEMBLY
The control pendant assembly is a hand-held control for use in the aircraft cabin. The pendant assembly is
connected to the control panel by a cable connector. The control pendant contains three switches and two
caution/warning lights: HOIST cable control, BOOM positioning, and ICS switches; OVERTEMP and cable 10-
foot CAUTION lights. The HOIST control is a directional and variable speed spring loaded to center switch with
marked positions of OFF, UP, and DOWN. As the switch is moved further away from OFF, the hoist speed
increases in the marked direction. When the switch is released, the hoist will stop. The BOOM position switch,
with marked positions OUT and IN, operates in the same manner as the HOIST switch, except the boom moves
in or out at a single speed. Two lights are installed on the control pendant. The 10-foot CAUTION light illuminates
when the hoist cable is within 10 feet or less of all stop limits. A red OVERTEMP light warns if overtemperature
condition in either the hoist lubrication systems or the hoist motor exists. Whenever the OVERTEMP light is on,
the hoist should be allowed to cool down until the light goes off. The ICS control switch, on the front of the
pendant, provides the operator with inter-helicopter communication.
