Remote Interlock
A remote interlock connection must be present in Class IIIB laser systems. This permits
remote switches to be attached in serial with the keylock switch on the controls. The
deactivation of any remote switches must prevent power from being supplied to any
lasers.
Key Control
A key operated master control to the lasers that prevents any power from being supplied
to the lasers while in the OFF position. The key can be removable in the OFF position
but the switch must not allow the key to be removed from the lock while in the ON
position.
Power-On Delays
A delay circuit is required that illuminates warning indicators for a short period of time
prior to supplying power to the lasers.
Beam Attenuators
A permanently attached method of preventing human access to the laser radiation other
than switches, power connectors or key control must be employed. On some LMI laser
sensors, the beam attenuator is supplied with the sensor as an integrated mechanical
shutter.
Emission Indicator
It is required that the controls that operate the sensors incorporate a visible or audible
indicator when power is applied and the lasers are operating. If distance (>2 m between
sensor and controls) or mounting of sensors intervenes with observation of these
indicators, a second power-on indicator should be mounted at some readily observable
position. When mounting the warning indicators, it is important not to mount them in a
location that would require human exposure to the laser emissions.
Warning Signs
Laser warning signs must be located in the vicinity of the sensor such that they will be
readily observed. Examples of laser warning signs are:
