Yellow Return/Inch-Up Button
The yellow return/inch-up button is used to stop the machine when it is in the “automatic” mode of operation. When
the operator depresses the button, almost anywhere in the stroke of the machine, it will return the ram to the up
position. This palm button assembly includes a double hub mounting box. It can be located between the two “run” palm
buttons, along with the red emergency-stop button, as part of the operator’s control station. (Please refer to page 18.)
Automatic Prior-Action Pushbutton Stations [Part No. LLD-700 (continuous) and Part No. LLD-702 (automatic single)]
According to ANSI B11.2 - 1995, control systems that include an automatic cycle mode shall require:
“Selection of the automatic mode; and a prior or deliberate action by the operator; and operation of the actuating means;
and an intended action by the operator before an interrupted cycle may be resumed.”
These prior-action stations have a recessed push button that must be depressed and released by the operator before
depressing the two palm buttons in order to initiate the continuous or automatic RUN type of press operation. This is
sometimes referred to as “walk-away” continuous.
Mount the remote stations on the machine so that it is convenient for the operator to depress and release these push
buttons prior to depressing the two palm buttons. These buttons may be mounted as part of the operator’s control station.
After releasing the button, the operator has a 5-second time period in which to depress the “run” buttons. If the operator
should wait longer than this time setting, the prior action must be depressed and released again.
PART NO. CTD-011 - FOOT SWITCH (optional)
(See enclosed Installation Manual No. KSL-001)
If a foot switch control is used, all personnel must be warned that it is NOT a point-of-operation safeguard. It is
the responsibility of the employer (user) to always provide an appropriate guard and/or device to prevent bodily
injury whenever a foot switch is used to initiate a machine cycle. (See ANSI B11.2 for safeguarding.)
When using a foot switch, please see page 11 for information on electrically interlocking or mechanically guarding
the point of operation. When installing the optional foot switch, be sure that the wiring schematics are referenced for
proper connections. Be sure to maintain the foot switch in first-class condition. It must always be wired properly and
the protection on the top, sides and front must always remain in place.
Never use a foot switch to operate this machine unless a point-of-operation guard or device is provided and
properly maintained.
The mechanical guard or device must be properly installed, used and maintained. It must always prevent all
personnel from bodily injury.
If the mechanical guard or device is not used, is removed or is defeated, an electrically interlocked method of
safeguarding must be used and connected to the safeguard interlock terminals (P7-5 and P7-6).
