System Setup
Low–Level Shutoff Setup (Model 970073)
Setup the low–level shutoff as shown in Fig. 4.
During system operation, as the ram approaches the
drum bottom, the top of the ram contacts the limit
switch. The switch shuts off the air to the ram.
NOTE:
The position of the air limit valve (2) 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. 4.
