External Safety Circuit (Interlock)
An external safety circuit (interlock) is integrated in the HP-MSM-HB, which you must connect to the safety
circuit of the laser. The safety circuit protects the measuring device from damage by switching off the laser
beam in the event of a fault condition within the device.
NOTICE
Danger of damage due to overheating
If the safety circuit is not connected, the device can be damaged due to overheating.
X
When connecting the laser control with the pins 1 and 4, please ensure that the laser is
turned off in case of an interruption
The following conditions open the safety circuit:
• The voltage supply at the HP-MSM-HB is not connected or interrupted
• There is an overtemperature at the absorber
• A referencing procedure is triggered during the measurement

Connection to the PC and connect power supply
The HP-MSM-HB requires a supply voltage of 24 V ±5 % (DC) for the operation. A suitable power supply is
included in the scope of delivery.
X
Use the adapter to connect the power supply to the 9-pin D-sub socket (RS485) of the device.
X
Connect the device to the PC via a crossover cable or to the network via a patch cable.
NOTICE
Damage/Destruction of the device due to overvoltage
When the electrical cables are disconnected during operation (when the power supply is ap-
plied), voltage peaks occur which can destroy the communication components of the mea-
suring device.
X
Connect/disconnect all plugs in a de-energized state only.
