SECTION 3—INSTALLATION OF COMPONENTS
Palm Button Assembly
(continued)
RED EMERGENCY-STOP BUTTON (Required)
The red emergency-stop button is used to stop the machine anywhere in its cycle. When the operator depresses the
button, it should stop the hazardous motion of the machine immediately. This palm button assembly requires either
a double-hub mounting box
Part No. CTK-003
, or a single-hub mounting box
Part No. CTK-004
. The button can
be located between the two run palm buttons as part of the operator’s control station (refer to page 26). A latch on
the side trips when the button is pushed. To reset the button, push the latch in.
Note: More than one emergency-stop button may be furnished for additional control stations or for convenience.
YELLOW TOP-STOP BUTTON
The yellow top-stop button is used to stop the machine when it is in the
“Walk-Away” Continuous,
Continuous-On-
Demand, or Automatic Single Stroke
mode of operation. When the operator depresses the button, almost anywhere
in the stroke of the machine, it will top stop or stop the machine at TDC (top dead center). This palm button
assembly requires either a double-hub mounting box
Part No. CTK-003
, or a single-hub mounting box
Part No.
CTK-004
. The button can be located between the two run palm buttons, along with the red emergency-stop button,
as part of the operator’s control station (refer to page 26).
PRIOR-ACTION STATION
The prior-action station has a push button that must be depressed and released by the operator before depressing
the actuating means in order to initiate the
Continuous
automatic RUN type of press operation. This is sometimes
referred to as
“Walk-Away” Continuous
. The prior-action station is also required when using the
Continuous-On-
Demand, Automatic Single Stroke, Two-Hand-Maintained Continuous, or Foot-Maintained Continuous
mode of
operation.
Mount the station on the machine so it is convenient for the operator to depress and release the prior-action push
button prior to depressing the actuating means. It may be mounted as part of the operator’s control station (see page
26). After releasing the button, the operator has a 5-second time period in which to depress the actuating means. If
the operator should wait longer than this time setting, the prior-action push button must be depressed and released
again.
Continuous
Mode of Operation
According to OSHA 1910.217 (b)(7):
• “(viii) Those clutch/brake control systems which contain both single and continuous functions shall be designed so that completion of continuous
circuits may be supervised by the employer. The initiation of continuous run shall require a prior action or decision by the operator in addition
to the selection of Continuous on the stroking selector, before actuation of the operating means will result in continuous stroking.”
According to ANSI B11.1-1988 Paragraph 4.13.3.3 Operating Modes for
Continuous
:
A control system with a CONTINUOUS mode of operation:
• Shall require a prior action or decision by the operator in addition to the selection of the CONTINUOUS mode of operation.
