must add 5.76 in. (146.3 mm) to the calculated safety distance for a one-beam floating
blanking window (ANSI formula). See your Shadow 8 user manual for further details about
fixed and floating blanking.
If you are using another Shadow light curtain, refer the appropriate Shadow user manual for
the additional distance factor to add to the safety distance formula for each blanking window.
Setting Micro-Inch
Micro-inch is the length of time in milliseconds that the Dual Safety Valve is open when the
operator presses the Run/Inch buttons on the Operator Station while the press is in Inch mode.
Normally, when the press is running in Inch (see Top-stop in Inch, page 4-9), the DSV is open
and the clutch engaged as long as the Run/Inch palm buttons are depressed. When Micro-inch
is enabled (see Wiring Micro-inch, page 2-33), the clutch remains engaged only for the length
of time specified in the Micro-inch setting unless the operator releases the Run/Inch palm
buttons before the period has expired.
You can enter Micro-inch values from 6 to 600 milliseconds. The default value, set at the
factory, is 100 mS.
To set Micro-inch, do the following:
1.
With power on to the WPC 2000 and the press in Inch mode, press the Reset/Select button
repeatedly until the “Micro-inch” indicator becomes lit (see Figure 3-10).
2.
Turn the WPC Settings key switch to “+” (counterclockwise) to increase the Micro-inch
time setting shown in the LED display, or turn the key to “–” (clockwise) to decrease the
setting.
INTERRUPTED STROKE
If an interrupted stroke occurs when Micro-inch is enabled, WPC 2000 automatically changes to
Two-hand Maintained Single-stroke mode. See Responding to an Interrupted Stroke, page 4-3.
