Rapid-Air SERVO FEED GAG FEED: 300 SERIES - Manual (Page 9)

MECHANICAL ROLL RELEASE SETUP
All Rapid-Air feeds are supplied with a manual pilot release. If the manual pilot release
is used, and we recommend this for press speeds faster than 250 SPM, then a bracket
has to be manufactured and attached to the press ram to actuate the pilot release
mechanism.
(Note: The roll release height adjustment screw should be backed off all the way to
prevent jamming when using the mechanical release.
The pilot release bracket should be made adjustable in order to set the roll release at
the proper press position. Some attention should be given to the bracket stroke length
so that the release mechanism is not jammed into the feed during the press stroke.
The 100 series pilot release actuator has a 1” stroke to full open with an additional
1.250” overtravel before bottoming out.
The series 200 and series 300 pilot release actuator has a 1” stroke to full open with an
additional 1.375” overtravel before bottoming out.
We do not offer any manufactured bracket to assist you because there are as many
combinations for stroke and clearance as there are presses manufactured today.
We do, however, ask that the bracket be designed to withstand considerable resistance
as the mechanism has to defeat or overcome the incoming air pressure or roller
pressure spring force depending on which servo unit you purchased.
ELECTRIC PILOT RELEASE
If an electric pilot release is used and the servo is a series 200 or series 300 then a
switch from the press has to be wired into the control box to control when the release
has to take place. If a series 100 was purchased then an optional pneumatic pilot
release has to be purchased.
OPTIONAL PILOT RELEASE #10900402
The optional pilot release package consists of a valve and a fitting. A switch signal
from the press has to be wired to the valve and an air line has to be connected to the
valve from the main shop air. This arrangement is seperate from the electrics supplied
by Rapid-Air
