Summary of user precautions regarding laser
For products with a laser safety class 2, 3R or 3B (See text of IEC 60825-1 for
complete precautions, subclause indicated in table):
Requirements

Class
3B 3R 2
Laser safety
Officer, 10.1
X
For 3R --required only if non visible radiation
Remote
interlock, 10.2
X
Connect to room or door circuits. Pin no 14 (LASER ON) of
the SLS connector can be used for this purpose.
Key control
10.3
X
Remove key when not in use.
Key control is provided when power supply is delivered by
LMI Technologies. To conform to safety requirements a key
control must be installed. Use pin no 15 (+24 VDC) of the
SLS connector to /connect/disconnect the power of the SLS.
Beam
attenuator
(Laser shutter)
10.4
X
When in use prevents inadvertent exposure.
Provided by LMI Technologies and permanently mounted
on the front of the sensor. See chapter 2, figure 1.
Emission
indicator device
X (X)
Indicates that the laser is energized. Required for 3R only if
nonvisible laser.
See chapter 2, figure 1.
Provided by LMI Technologies and permanently mounted
on the side of the sensor. One of the LEDs is always lit.
• The yellow LED is lit when the sensor signals Invalid,
e.g. no object inside the measurement range, too little
light scattered back to the detector, to much light
scattered back to the detector.
• The green LED is lit when the measurement is Valid
Warning signs,

Required for all operator and maintenance personnel.
Emission delay
LMI Technology’s sensors can be equipped with two different types of emission
delay. One (called Laser ON delay) will always cause a short delay every time
the laser control signal is turned on, before the laser actually starts emitting laser
light. The other type (called Power ON delay) will only cause a delay when the
sensor is first powered up. All subsequent cycling of the laser control signal will
control the laser without any delays. See quality record.
