8.4 Safety Circuit
Connect this port to your laser system (Safety PLC or Emergency off).
The Safety Interlock protects the MSM+ HB from damage by switching off the laser in the following cases:
• The voltage supply at the MSM+ HB is not connected or interrupted
• There is an overtemperature at the absorber
• A referencing procedure is triggered during the measurement
The interlock connection provides two redundant safety circuits.
