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.
Clutch Air Pressure Switch
This switch monitors the system air pressure. See Installing Clutch and Counterbalance 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 1000 is used
with a Foot Switch or in One-hand operating mode. WPC 1000 tests the Shadow inputs every
time that the press is started and stopped. See Installing a Light Curtain, page 2-18 for more
information.
WPC 1000 is designed to be used with a Shadow light curtain. If you order WPC 1000
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.
Displays
WPC 1000 can be ordered with either a Standard or Optional Counter/Crank-angle Clock
display.
Standard Display
The Standard display provides the following features (see Figure 1-3, page 1-5):
• Digital LED Display–A highly visible, three-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 (see next item) selected. The LED readout also displays WPC
1000 fault codes and abbreviated text messages.
