Connecting Stop Circuits to the Control
GUARD AGAINST ELECTRIC SHOCK HAZARD
Do not connect wires to AC power source until you are done with all other installation procedures.
Failure to comply with these instructions could result in death or serious injury.
DO NOT USE SHADOW LIGHT CURTAINS ON FULL-REVOLUTION POWER PRESSES
• DO NOT use Shadow 8 safety light curtains on full-revolution clutched machinery, which cannot
be stopped in mid-stroke.
• Use Shadow 8 safety light curtains only on machinery that can be stopped at any point in the
stroke or cycle.
Failure to comply with these instructions will result in death or serious injury.
PREVENT PRESS FROM BEING ABLE TO MOVE AFTER INTRUSION
• Ensure that Shadow 8 is wired to the emergency stop circuitry of the press.
• Ensure that any stop initiated by the light curtain is an immediate stop, one that occurs
immediately after the stop signal is sent to the machinery. If the light curtain is not correctly
wired in this way, the press may continue its stroke after an intrusion is detected.
Failure to comply with these instructions will result in death or serious injury.
AVOID WIRING STOP CIRCUITS THAT ARE NON-OPERATIVE IN SOME MODES
Wire the light curtain in series with your press control circuit so the stop signal from the light curtain
stops the machine immediately in all modes of operation, including Inch.
Failure to comply with these instructions will result in death or serious injury.
