point, with the press running in Continuous and the heaviest die installed. The results of
the test provide the stopping time (Ts) value specified in both OSHA 1910.217 and ANSI
B11.1-2009 (see Appendix A).
•
Counter and Counter Preset–The counter maintains a cumulative total of the number of
strokes made by the press. When the count total reaches the value set on the Counter Preset
indicator segment (see page 4-6), WPC 2000 stops the press. The counter is reset to “1”
with the Reset/Select button. The counter preset feature is useful for batch sizing or
periodic QC checks.
•
Micro-inch–A feature that allows you to set the amount of time that the Dual Safety Valve
is open in Inch mode when you push the Run/Inch palm buttons. Normally, in Inch the
DSV is open for only as long as the Run/Inch buttons are depressed. The Micro-inch
setting specifies the length of time the DSV is open regardless of how long the Run/Inch
buttons are held. Allowing finer adjustments than are possible in Inch, Micro-inch is
designed to facilitate setup on high-speed or short-stroke presses. Requires installation of
optional Micro-inch selector switch (see page 1-2).
•
Error Codes–WPC 2000 displays a two-digit code preceded by the letter “E,” “F,” or “H
whenever the press is stopped because of a fault. The two-digit code identifies the specific
problem that caused the fault. The initial letter indicates how the fault should be reset, and
in the case of F and H errors, specifies the processor (A or B) that detected the problem.
Underlying causes and remedies for each fault code are provided in Chapter 5.
•
Lockout–Selected error codes that are associated with serious error conditions generate the
lockout message “Loc,” which displays in the digital LED readout when the error has been
reset. The lockout function provides an added safety feature to WPC 2000, forcing the
operator to perform two different Reset operations. The “Loc” message is cleared by
turning the Stroke Select key switch to “OFF,” then to “INCH.”
Optional Features
WPC 2000 can be ordered with any of the following optional features:
•
Counterbalance Air Pressure Switch–Operating identically to the clutch air pressure
switch, this switch is used with the counterbalance air supply on presses equipped with
counterbalances, as required by OSHA regulations.
•
Four-channel Programmable Cam Switch–Provides cam timings for feed, pilot release,
air blow-off, lubricator, or other non-safety press equipment.
•
One-hand Control–A low-force switch that can be used with WPC 2000 running One-
hand/Two-hand/Foot firmware and equipped with a Shadow light curtain guarding the
point of operation. The One-hand Control switch can be mounted on or near the press,
allowing the operator to press the switch as part of his normal hand motion after loading a
part.
•
Foot Switch–A device that frees the operator’s hands for increased, fully-guarded
protection and productivity. One-hand/Two-hand/Foot firmware is required, and a Shadow
light curtain must be installed.
•
Bar Mode Control–Allows operators and setup personnel to bar the press by hand for die
setting and adjustment. Recommended for smaller-capacity presses of 65 tons or less.
