Shadow Light Curtain Test
WPC 2000 tests whether its light curtain inputs are working properly whenever the press is
started and stopped.
Perform the following test to verify that your Shadow light curtain is installed and wired
correctly and operating properly, referring also to the troubleshooting information in your
light curtain user manual if necessary. If you have more than one light curtain on your press,
perform this test on each light curtain.
1. Power up the light curtain.
2. Check to see whether there is power to the Shadow. On Shadow V and Shadow VI units,
the amber (Power On) LED on the transmitter indicates that the light curtain has power.
On Shadow VII units, the presence of power is indicated by an illuminated diagnostic
code LED display. The green Power LED on the optional Shadow 8 control or the LEDs
on Shadow 8 Main Receiver and Transmitter indicate the presence of power. On
Shadow 9, the green power LED on the optional control, the green POWER LED on the
transmitter, and the ON/OFF LED illuminated red or green on the receiver indicate the
presence of power.
• If the Shadow has power, go to the next step.
• If the Shadow does not have power, turn off the light curtain, and check the input power
wiring and the power fuse. (The fuse is located in the Shadow V receiver or in the
Shadow VI, Shadow VII, Shadow 8, or Shadow 9 (optional) control box. The Shadow
VII DIN controller has no fuse.) Rewire power connections and/or replace the fuse if
necessary. Power up again. (On Shadow V and Shadow VI units, if there is still no
power, turn off the transmitter and try replacing the amber indicator. Power up again.)
If there is still no power to the unit, call Wintriss Tech. Support.
3. At the Shadow receiver, check to see whether the green (Curtain Unobstructed) indicator
is lit.
• If the green indicator is lit, go to the next step.
• If the receiver’s red (Curtain Obstructed) indicator is lit, realign the light curtain heads.
If the red indicator is still lit, check the interrupt circuit (Shadow V and Shadow VI) or
the Light Curtain Test mode jumper (Shadow VII, Shadow 8, or Shadow 9). To check
the interrupt circuit, make sure that the following terminal reads 0 V relative to ground:
Shadow V: INT terminal in the transmitter (see Figure 4 at end of manual)
Shadow VI: pin #19 on auxiliary TB4 in the control (see Figure 14 at end of manual)
Shadow VI/WPC Interface Board: pin #5 on TB4 (see Figure 15 at end of manual)
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.
