Safety Circuit PLM In (option)

This connection is only used if you are using a PowerLossMonitor PLM for power measurement.
NOTICE
Danger of damage due to overheating
If the safety circuit is not connected, the device can be damaged due to overheating.
X Connect the Safety Interlock of the PowerLossMonitor PLM to the MSM+ HB.
X Check that the laser is switched off properly by the external safety circuit in the event of a
fault.
The Safety Interlock protects from damage by switching off the laser in the following cases:
• The water flow is too low.
Make sure that the Safety Interlock MSM connector on the PowerLossMonitor PLM is connected to the
Safety Circuit PLM-In connector on the MSM+ HB. Use the enclosed 8-pin cable, which is pre-assembled
on both sides.
The interlock connection provides two redundant safety circuits.

Safety Circuit Fiber Out (option)

This connection is only used if you are using a fiber bridge to connect a laser.
The Safety Interlock protects against damage by switching off the laser in the following cases:
• The fiber is not mounted correctly.
Make sure that the safety interlock connection on the fiber holder is connected to the Safety Circuit Fiber Out
connector at the MSM+ HB. Use the enclosed 3-pin cable.
