Output is not stable, or
noisy
Power supply to height sensor is
noisy
Use a well-regulated DC power supply
to provide proper voltage and current to
height sensor unit.
External source of noise is causing
electrical interference
External sources of electrical or radio
frequency noise can interfere with the
operation of the head. Move the control
electronics away from motors and motor
drives. Make sure the routing of the
control cable is separate from wires that
contain high voltages or high current.
Part or cutting head is not grounded
or a ground loop is present
Poor grounds or poor grounding
schemes can cause significant noise
issues. In many cases a separate
copper grounding rod needs to be
inserted into the ground at a location
close to the machine. From this
grounding point insure that the cutting
head and the part are grounded. Also
make sure that any equipment is
adequately grounded.
Status Signal remains on
after calibration for more
than 1 second and

HSU Utility
indicates Cal
Fault Short
Broken or disconnected sensing
cable or nozzle
This can be an indication that the white
sense cable is broken or there is a
problem with the nozzle assembly.
Replace the suspected components.
Status Signal remains off
after calibration and

HSU Utility
indicates Cal
Fault Open
The sensing cable or the nozzle
assembly is shorted
This can be an indication that the white
sense cable is shorted or there is a
problem with the nozzle assembly.
Check the nozzle assembly for debris.
Replace the suspected components.
Ready Signal remains off
and
Basic+ HSU Utility
indicates Overtemp or
Excessive Temperature
Difference (<<)
Temperature fault
Inspect all optics, including fiber (if
applicable).
If system is otherwise functioning
normally but ambient temperature is
high, increase the temperature limits
using
Basic+ HSU Utility
.
Ready Signal remains off
and
Basic+ HSU Utility
indicates Cable Break
Sense cable broke after calibration
Inspect sense cable and tip retaining
assembly (nozzle). Bad connections or
intermittent connections usually cause
this fault condition. Recalibrate to clear
fault.
