Using Auto Carry-up

DANGER
!
INCORRECT AUTO CARRY-UP ANGLE
• Ensure that the Auto Carry-up angle is correct. If the operator can reach the pinch point, the
Auto Carry-up angle must be set so that any hazardous openings are smaller than ¼" by the
time the crankshaft reaches the Auto Carry-up angle.
• Determine the Auto Carry-up angle for each tool, based on the crank angle at which the
tool's hazardous openings are smaller than ¼."
• Change the Auto Carry-up angle to the correct value when you change tools.
Failure to comply with these instructions will result in death or serious injury.
NOTICE
The following Auto Carry-up function also applies to Foot Control. For more information
about using Foot Control for Single Stroke mode, see "One-hand Operation, Single Stroke
Mode," page 369; "Foot Operation, Single Stroke Mode," page 372; and "Switch 3 – One-
hand Control or Foot Switch Mode," page 243
Auto Carry-up is another name for operator station mute. Auto Carry-up bypasses the
operator station during the non-hazardous portion of the stroke. When the operator releases
his hands from the palm buttons, the press automatically completes the stroke and stops at
TDC. So in order to properly set the Auto Carry-up Angle value (in degrees), you need to
know at what point it is safe to let the operator's hands release from the palm buttons.
Pinch points that are less than 1/4" (6 mm) are considered non-hazardous to the operator. To
determine the Auto Carry-up angle, you need to determine at what crank angle, in degrees,
the pinch point openings have closed to less than 1/4" (6 mm). Set the Auto Carry-up angle
to at least that number of degrees.
With large presses where the stroke length is large and press speed is slow, you must ensure
that the operator cannot release the buttons and reach the pinch point before it closes. This
applies only when two-hand control is used to safeguard the point of operation and only if
any opening allowing access to the pinch point is 1/4" (6 mm) or larger.
The factory setting for Auto Carry-up angle is different, depending upon whether you have
WPC firmware for light curtains:
• If you have light-curtain firmware, the Auto Carry-up angle is factory set at 149° ; you
must set the Auto Carry-up angle at 149° or less.
• If you have non-light-curtain firmware, the Auto Carry-up angle is factory set at 170° .
Set the Auto Carry-up angle at the correct value to protect the operator.
