1-4 Introduction
Other Components
Dual-monitored Safety Valve (DSV)
The DSV controls the flow of air to the press clutch and brake. Wintriss provides 3/4 in. and
1 in. Ross DM2 DSVs. See Installing a Dual Safety Valve, page 2-9 for further details.
System Air Pressure Switch
This switch monitors the system air pressure. See Installing Air Pressure Switches, page 2-11
for additional information.
Shadow Light Curtain
The Shadow light curtain is a presence-sensing device that places an infrared light field
between the point-of-operation and the operator. When an object, like the operator’s hand,
enters the sensing field and blocks a light beam, the light curtain detects the object and issues
an Emergency-stop command to the press.
The Shadow light curtain is required for point-of-operation guarding if WPC 2000 is used
with a Foot Switch or in One-hand operating mode. Multiple light curtains can be wired to a
WPC 2000. WPC 2000 tests up to two pairs of Shadow inputs every time that the press is
started and stopped. See Installing a Light Curtain, page 2-18 for more information.
WPC 2000 is designed to be used with a Shadow light curtain. If you order WPC 2000
without a light curtain, the control enclosure does not have a Mode Select switch, and the unit
operates only in Two-hand mode.
The light curtain is placed between the Operator Station and the die space. Shadow’s
mounting-bracket design allows plenty of room for adjustment.
WPC 2000 Display
The WPC 2000 display provides the following features (see Figure 1-1):
•
Digital LED Display–A highly visible, six-digit readout which shows press speed (SPM),
crankshaft angle, stopping time, and other press parameters. The information displayed
depends on the current Stroke Select setting (see Control Enclosure, page 1-1) and the
indicator segment selected (see next item). The LED readout also displays WPC 2000 fault
codes and abbreviated text messages.
•
Indicator Segments–Ten LED indicators which, when illuminated (i.e., selected), display
press information in the digital LED readout. To select a segment in the upper group of six
segments, press the Reset/Select button until that segment is illuminated. The segments in
the lower group of four segments can only be selected when WPC 2000 is in Inch mode.
When illuminated, indicator segments display press speed, crankshaft angle, 90° stop-time
test result, stopping time, stopping angle, stroke counter, counter preset, top-stop angle,
auto carry-up angle, stop-time limit, micro-inch time, and cam On/Off angles. See Viewing
and Setting Press Parameters, page 3-1.
