5.4.5 Remote Interlock
The Remote Interlock is for external interlocks such as additional Emergency Stop controls or
a motion control system. This is the Remote Interlock required by EN 60825-1:2007. It is a
dual channel category 4 system and requires two volt-free contacts connected to PL91.
5.4.6 E-Shutter
This function prevents laser output when the process cabinet door is open. It is a dual channel
category 4 system and requires a double pole interlock switch on the process cabinet door.
The function is provided by control of the pump diode PSUs and requires two volt free
contacts connected to PL81. See section 7.6.6 for more details.
5.4.7 FCMS
The internal monitoring of the FCMS will prevent laser output should the delivery fiber fail or if
the temperature in the PIPA-Q optical connector is too high, or if the PIPA-Q connector is not
mated with an appropriate receiver.
5.4.8 Performance Level of Safety Functions
The performance level of the six safety functions have been designed using
EN ISO 13849:2008 as a guide. Further information can be provided by request from SPI
Lasers.
