1. Press the desired oor level button. See Figure 9-1. The coil in the motor
starter magnetically closes the high voltage contacts and the power circuit
to the motor starter. See Figure 9-2. This action turns the motor in the
needed direction.
2. The brake is released. The motor turns the gears in the reducer, which
in turn rotates the keyed drive sha. The drive sprockets on the sha
turn resulting in the raising or lowering of the li chains. The li chains
are fastened to safety cams, which are bolted to the carriage uprights.
Adjustments to the safety cam levels the carriage deck.
3. When the carriage arrives at the next level, the oor level limit switch is
activated by a carriage mounted cam. See Figure 9-3. When the oor limit
switch is activated, the switch cuts the power to the motor circuit. The
motor starter contacts open, the motor stops, and the brake is applied. This
stops and holds the carriage position.
