Single-stroke Mode Test with Light Curtain(s)
To test Single-stroke mode when light curtains are installed, perform the following steps,
referring to Figure 3-14, Figure 3-15, or Figure 3-16 for LED locations. To verify Single-
stroke operation on a press without light curtains, go to the next test (page 3-47).
1. Set the Stroke Select switch to “SINGLE,” and verify that the “Single stroke select” LED
on the WPC 2000 Display board is lit.
2. Verify that the light curtain is unobstructed and that the “Light curtain A1 input” and
“Light curtain A2 input” LEDs on the WPC 2000 Main Processor board are lit. (If you are
testing a second pair of light curtains, verify that “Light curtain B1 input” and “Light
curtain B2 input” LEDs are lit.) These LEDs turn off when the light curtain is obstructed.
3. Press and hold both Run/Inch palm buttons on the Operator Station, observing the ram’s
motion.
• If the ram makes a complete stroke, stopping at top dead center, go to the next step.
• If the ram moves but does not make a complete stroke or does not stop at top dead
center and a fault code between F80 and F89 (or between H80 and H89) displays, there
is a problem with the overrun limit switch. Try the remedies suggested for overrun limit
switch faults, starting on page 5-18; then, inch the ram to the top of the stroke and repeat
this test. If the ram still does not make a complete stroke or does not stop at top dead
center, call Wintriss Tech. Support.
INJURY DURING TESTING
• Keep all personnel away from the press during testing.
• Be sure there is no die or other tooling in the press during testing.
Failure to comply with these instructions will result in death or serious injury.
CONTINUOUS MODE USED ON PRESS NOT GUARDED PROPERLY FOR CONTINUOUS
Disconnect the “Continuous” position on the Stroke Select switch to prevent your press from being
run in Continuous mode if it is not guarded correctly for use in Continuous mode. Also cover the
“CONT” label on your control’s Stroke Select switch.
Failure to comply with these instructions will result in death or serious injury.
ELECTRIC SHOCK HAZARD WHEN WORKING INSIDE ENCLOSURE WITH POWER ON
