Light Curtain
Some machines are equipped with an optional light curtain. The light curtain is redundant and self
checking. The control signals from the light curtain are included as safety devices in the safety circuit. On
machine power up, the light curtain must be reset by turning the key switch to ‘Reset’ for at least ½ second.
Exhaust Fan
Some machines are equipped with an exhaust fan. The exhaust fan is provided to exhaust fumes from the
work area. The exhaust flange should be connected to an appropriate ducting system that is capable of
receiving 150 CFM (cubic feet per minute). Insufficient air flow through the exhaust system generates an
error.
NOTE: Installed safety devices vary from model to model.
