Introduction 1-1
Chapter 1. Introduction
WPC 2000 Wintriss Clutch/Brake Control is an easy-to-use, dual-microprocessor-based
system that controls part-revolution mechanical power presses. Housed in a single modular
enclosure, both microprocessors function independently, have different power supplies, and
provide separate information to the operator. As a result of its “dual diverse redundancy,”
WPC 2000 is able to provide optimum clutch/brake control and improved operator safety
while increasing productivity.
WPC 2000 meets or exceeds all ANSI B11.1-2009, OSHA 1910.217, and Canadian Z142-02
standards for Control Reliability, the benchmarks that govern the operation of mechanical
power presses. Control Reliability demands that a single component failure in a clutch/brake
control circuit not prevent the normal stopping action of the press, not create an unintended
stroke, and not allow initiation of a subsequent stroke until the failure has been corrected.
WPC 2000 Components
WPC 2000 can be configured as a complete system with all the components necessary to
operate a pneumatic clutch/brake system.
Resolver
The resolver, which is mounted on the press, turns one-to-one (1:1) with the crankshaft,
allowing WPC 2000 to know the exact position of the crankshaft on every stroke.
The resolver is similar to an electrical generator and works on the principle of inductance.
The resolver’s two outputs vary in amplitude and phase as the resolver turns. WPC 2000
translates these analog signals to a number that indicates the position of the resolver (and
press crankshaft) in degrees.
The resolver eliminates the need for a mechanical rotary limit switch. Operators no longer
have to climb on top of the press to make timing adjustments. In addition, the resolver on the
WPC 2000 can be shared with other Wintriss resolver-based products, such as DiPro 1500.
Control Enclosure
The WPC 2000 control enclosure (see Figure 1-1, page 1-2) can be ordered with the display
and controls mounted on the front (center mount) or on the left (left mount) or right side (right
mount). Up to three of the following selector key switches can be mounted in the enclosure:
•
Stroke Select (Standard)–Provides switch settings for selection of Inch, Single-stroke, or
Continuous operation or Inch or Single-stroke.
•
Mode Select (Optional)–Provides switch settings for selection of One-hand, Two-hand, or
Foot operation. Optional One-hand/Two-hand/Foot firmware is required for use of One-
hand and Foot settings.
