Shadow Light Curtain Test

WPC tests whether your Shadow(s) are working properly by momentarily de-energizing the
Shadow transmitter whenever the press is started and stopped. WPC also ensures that the
Emergency stop relays are open.
WARNING
!
ELECTRIC SHOCK HAZARD WHEN WORKING INSIDE ENCLOSURE WITH POWER ON
• DO NOT touch electrical connections or circuit boards.
• Use test equipment only on the terminals specified in the instructions.
• Ensure that this test is performed by qualified personnel.
Failure to comply with these instructions could result in death or serious injury.
Perform this test to verify that your Shadow V or Shadow VI light curtain is wired and
installed correctly and operating properly. If you have more than one light curtain on your
press, perform this test on each light curtain.
1. Power up the light curtain. Look at the Shadow transmitter to see if the amber (power-on)
indicator is illuminated.
• If the transmitter's amber indicator is lit, go to step 2.
• If the transmitter's amber indicator is not lit, power down the light curtain, check the
wiring to the transmitter and check the power fuse (in the receiver for Shadow V, in
the control box for the Shadow VI) and replace if necessary. Power up again. If the
amber indicator is still off, power down the transmitter and replace the indicator.
Power up again. If the amber indicator is still not lit, contact Wintriss Tech Support.
2. At the Shadow receiver, see if the green (curtain clear) indicator is lit.
• If the receiver's green indicator is lit, go to step 3.
• If the receiver's red indicator is lit, realign the light curtain heads. If the receiver's red
indicator is still lit, check the interrupt circuit. The following terminal on your unit
should read 0 (zero) volts relative to ground:
Shadow V: INT terminal in the transmitter
Shadow VI: pin #19 on TB4 in the control
Shadow VI – WPC Interface Board: pin #5 on TB4
If the terminal does not read 0 (zero) volts relative to ground, check and correct the
ground wiring for the unit. If this does not cause the green indicator to come on,
contact Wintriss Tech Support.
• If neither the receiver's green nor red indicator is lit, power down the unit and check
the wiring to the receiver. Also check the power fuse (in the receiver for Shadow V,
in the control box for the Shadow VI), and replace if necessary. Power up again. If
