The laser head can be made operational by selecting to “arm” and “disarm” the laser head.
Arming means turning the head power supply on; the armed head is then able to generate a laser
beam. Disarming (turning the head power supply off) brings the laser head to a safe state where
generating a laser beam is altogether impossible.
Built-in safety mechanisms prevent misuse and unexpected behavior in case of an
emergency. The key switch protects the laser head from being armed by children and other
unauthorized people. Arming the laser head is always done manually by the user, by pressing a
button. Special circuitry prevents arming during an internal electrical malfunction. The laser head is
automatically disarmed in case of an emergency such as a loss of the mains supply (grid power), PSU
failure, breakage, or disconnection of the laser head cable. After disarming, the system remains in a
safe state, and rearming always requires the user to press the button.
Additional safety mechanisms can be incorporated into the system by adding up to two
external switches (e.g., a limit switch, a key switch, or an e-stop). There is also an additional
extension connector for future purposes
Additional feature are industry-standard screw connectors. A dedicated, low-noise desktop
power supply unit assures compatibility and reliability as well as eliminates problems caused by
using third-party power supplies. The general status (power on, arming, laser working) may be
inspected at a glance by looking at the three LEDs.
