4-2 Operation
This chapter shows you how to operate your WPC 2000, using each Stroke and Mode setting.
TWO-HAND CONTROL TOO CLOSE TO HAZARDOUS AREA
Verify at each shift change that any moveable Two-hand controls are located at least the safety
distance from the pinch point or hazardous area.
Failure to comply with these instructions will result in death or serious injury.
FAULTY INSTALLATION
• Ensure that wiring is correct.
• Use only safety-certified components for safety functions, including interlock switches used in
safety applications.
• Install guarding to prevent access to hazardous areas. Prevent access to hazardous areas
over, under or around any guarding devices.
• Ensure that there is one active Operator Station for each operator if you are using Two-hand
mode.
• Use Foot Switch or One-hand Control only with properly installed light curtains.
Failure to comply with these instructions will result in death or serious injury.
CLEARING “LOC” WHEN YOU TURN ON POWER TO THE PRESS
Whenever you turn on power to your press, the message “Loc” appears in the LED display (see
Lockout Message, page 5-3). To clear this message, simply turn the Stroke Select switch to “OFF”
and then back to the previous operating mode. If the Stroke Select switch is already in the “OFF”
position when you power up, turn it to the desired stroke selection to clear the “Loc” message.
Once “Loc” has been cleared, you can resume operation.
PRESS STOPS WHEN SYSTEM FAULT DETECTED OR LIGHT CURTAIN BLOCKED
• The WPC 2000 stops the press if a system fault is detected or if the light curtain is blocked
during the non-muted portion of the stroke.
• If the press stops, the Interrupted Stroke LED on the WPC 2000 display (see Figure 1-1,
page 1-2) will flash and a three-character fault code, consisting of the letter “E,” “F,” or “H”
followed by a two-digit number, will appear in the digital LED display.
• When an Interrupted Stroke occurs, WPC 2000 automatically switches to Two-hand Maintained
Single-stroke mode for the remainder of the stroke (see Responding to an Interrupted Stroke,
page 4-3). To clear a system fault, press the Reset/Select button on the WPC 2000 display.
