Function or Command Description Operating Mode
Interrupted stroke Continuous If an operator releases a RUN button during a down stroke, the
press stops immediately. If within five seconds of stopping, an
operator releases both RUN buttons and presses them again,
the press continues the downstroke. If more than five seconds
elapses, the operator must inch the press to top, select
continuous mode, and follow the first Continuous procedure
above..
Interrupted stroke SingleĆstroke Same as Continuous mode except there is no time limit on
reĆapplying the RUN button.
AntiĆtieĆdown All The press will not start if you tie down one or more RUN
buttons. After all RUN buttons are released, the operator must
press both RUN buttons at a station simultaneously, and/or
operators at active stations must press all RUN buttons within
five seconds of each other to start the press.
The same applies to the pair of INCH buttons.
AntiĆrepeat SingleĆstroke The press is limited to a single stroke, even if the operator
continues to press both RUN buttons. The operator must
release both RUN buttons and press them again to start press
motion.
Inch The same applies to a pair of INCH buttons as described for
SingleĆstroke.
Motion detector SingleĆstroke
Continuous
The clutch/brake controller detects press motion using your
motion detector which provides a 120AC input signal. This is a
configurable option.
TopĆstopĆCheck All The clutch/brake controller signals a worn or faulty brake by
monitoring the TopĆstopĆcheck cam inputs. Should it see the
TopĆstopĆcheck cam closed after a normal cycle stop has been
initiated and before the press comes to a top stop, it prevents
the press from restarting and energizes the brakeĆfault output.
