Rapid-Air SERVO FEED: 200T & TX - Manual (Page 8)

MECHANICAL ROLL RELEASE SETUP
All Rapid-Air feeds are set up to add a mechanical pilot release. If the mechanical pilot
release is used, and we recommend this for press speeds faster than 250 SPM, then
a bracket must be fabricated 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 bracket should be made adjustable for tuning to the press position in which the roll
release should occur. 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 .750” overtravel before bottoming out.
The series 200 and series 300 pilot release actuator has a 2” stroke to full open with an
additional .750” 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 #10900449 (100 series)
The optional pilot release package consists of a valve, fitting, relay and solenoid cable.
A switch signal from the press has to be wired to the control panel and an air line has
to be connected to the valve from the main shop air. The relay and solenoid cable will
have to be mounted and wired in the electric cabinet if it is to be used with the
program.
