Emergency safety switch (E-STOP)
The laser will not operate unless the +24 V DC emergency stop power and ground signals are
connected as shown below. Laser is ON if power is applied to pin 12, OFF if power is not applied.
An external
emergency safety switch
(E-STOP), which is normally closed, should be included in
the image system.
