safety glasses whenever the laser system is within sight.
KLMC Box
The Kern Laser Monitor Controller has multiple lights that will help indicate if there is a problem with
the laser system. Make sure that all connections on the back of this box are secure before
troubleshooting any further. There are three different colors that you may see at any given time.
GREEN – This indicates that this function is satisfied and ready to laser cut or engrave.
AMBER – This indicates that there was an alarm but has been corrected. To clear this amber light
simply cycle the key switch and wait five seconds for the light to turn green.
RED – This indicates an alarm. To troubleshoot the alarm please refer to its corresponding section
below.
NOTE: The DSP Enable and Laser Enable will not show green until the cut or engrave has started.
KLMC Box
E-STOP
This light indicates that an emergency stop switch has been activated. Each system has from 2 to 4
emergency stop buttons depending on the table size. To disengage an emergency stop button, twist
and pull back on the red knob.
Over Temp
This light indicates an over temperature signal has been received from the laser unit. The KLMC will
shut off power to the laser to protect it from overheating. This fault may be caused by the room
temperature being too warm. Room temperatures should be kept between 60 - 80 degrees. Also
check that your chiller is set at a cooling temperature of 68–70 degrees Fahrenheit.
