Rapid-Air SERVO FEED: 100C, 100D series - Manual (Page 6)

All the 100 feeds have an optional
mechanical pilot release. If the
mechanical pilot release is used,
(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 bracket should be made adjust-
able 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
ROll RElEASE SET-UP AND CAblING
Mechanical Roll Release Set-Up
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.
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 the roller
pressure spring force.
OPTIONAL MANUAL PILOT RELEASE
The optional manual pilot release
should be ordered at the time of
purchase but can be added at a later
date. Rapid-Air would like to perform
the installation if at all possible.
OPTIONAL ELECTRIC PILOT RELEASE
The optional pilot release pack-
age 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.
The electrical control enclosure is
shipped completely ready to be con-
nected to the mechanical feed. Con-
nected to the bottom of the enclosure
are (2) cables with keyed screw type
connectors for connection to the
motor.
Electrical Cables and Air Line
Position the electrical enclosure at a
convenient location near the mechan-
ical feed and attach the cables. The
motor cables are easily identifiable by
the amount of pins in the plugs.
An air line must be connected from
the shop air to the air inlet of the
servo feed. The air should be at least
80 PSI continuous and should be dry fil-
tered and lightly lubricated for the best
operation of the servo feed. The air
inlet on the servo feed is a 3/8-18 NPT
pipe tap. The minimum air line size
requirement is 1/2” ID hose. - (2 CFM)
