Electrical Crossover Setup (Model 970063)
The electrical crossover is setup as shown in Fig. 5
and the Unloader Crossover (A) must be connected to
a 120 Volt, 60 Hz supply.
During system operation, as the ram approaches the
drum bottom, the top of the ram contacts the limit valve
switch. The switch shuts off the air to one air motor,
and starts the other air motor. This allows constant
material flow and changing out of material drums.

NOTE: Air is supplied to each ram at all times. Air is
only toggled between air motors.
NOTE: The position of the empty level indicator kit (B)
on the ram determines when the ram air motor is
turned on and off. During operation, this position can
be adjusted as desired. See Fig. 5.
