Safety Concept Of The Laser Tool - Stepcraft Dl445 Betriebsanleitung

• Always use the system's vacuum assist feature when working with the laser tool.
• Use caution when cutting. Many materials have the potential to suddenly burst into flames when cut with a
laser – even materials that may be very familiar to the user. Always monitor the laser head when it is operating.
• Clean the laser. A buildup of cutting and engraving residue and debris is dangerous and can create a fire hazard
in its own right. Keep your laser system clean and free of debris. Regularly remove the vector cutting table to
clean any small pieces that have fallen through the grid.

1.5 Safety Concept of the Laser Tool

Never bridge the safety system manually on purpose. Use of the laser tool for operations different from those
intended could result in a hazardous situation with high probability of superficial injury.
STEPCRAFT has incorporated specific nine-level safety features into the model DL445 in order to meet the requirements
of 21 CFR 1040 and the International Standard IEC 60825-1. These safety features include:
• Safety switch to ensure the mounting position. Wrong mounting position / switch OFF leads to an immediate
deactivation of the laser beam (1. interlock system).
• Cabinet design of laser head with a visual protection brush, which encloses the laser diode and serves as a radial
visual sight protection of its beam path to avoid scattered radiation.
• Operating LED indicator on the front of the laser head illuminates red when laser beam is active.
• Toggle signal to verify an active computer connection. A disconnection between laser controller and the CNC
control software will deactivate the laser beam immediately (2. interlock system).
• Laser operation only possible after software request of positive job status signal (3. interlock system).
• Key operated switch for control unit.
• Emergency stop switch for control unit.
• Safety goggles to avoid eye exposure to direct or scattered radiation.
• Fine particulate air filter to reduce fine dust pollution.
