2-54 Installation and Checkout
If the Machine Run/Stop LED is illuminated green, but you cannot start the press, check the
stop relays on the relay board on the Shadow 8 Main board (see Figure 2-20, page 2-32),
following the instructions in Checking and Replacing Control Relays in Optional Shadow 8
Control Box, page 4-9.
If the light curtains are connected directly to a new WPC clutch/brake control, check to make
sure that the light curtain output type jumper on the WPC Main Processor board is set to
“PNP” and the light curtain test mode jumper is set to “INT” (for Internal). See the
appropriate WPC manual for further details.
Shadow 8 Control Box or WPC Power LED Dims and Blinks
If the Power LED on the Shadow 8 control box or WPC enclosure dims and blinks, a Receiver
or Transmitter segment has shorted the 24 volt power internally. To determine the source of
the problem, turn off power and unplug the Main Transmitter; then, turn the power back on. If
the Power LED still dims and blinks, a Receiver segment is defective. If the Power LED
behaves normally, a Transmitter is at fault.
If the problem is in a Receiver and there are no Extensions, the Main Receiver is defective.
Return the unit to Wintriss for repairs. If there are Receiver Extensions, turn off power and
disconnect the last Extension; then turn the power back on. If the Power LED behaves
normally, the Receiver Extension you removed is defective. If the Power LED dims and
blinks, another Extension is at fault. Continue removing Extension heads, one at a time, until
you find the defective Receiver segment. Return the defective unit to Wintriss for repairs.
If the problem is in a Transmitter, follow the same process to isolate the defective Transmitter
segment. Return the defective unit to Wintriss for repairs.
