Possible Causes:
•
The internal humidity sensor has detected a Relative Humidity (RH) reading inside the laser
chassis that is greater than 95%.
Because relative humidity readings above 95% may indicate a condensing atmosphere, leading to cata-
strophic laser damage, lasing is halted when this threshold is exceeded. If you are connected to the i401’s
Ethernet port, access the i401 web page to verify the fault condition. If you are not connected to the
i401’s web page, refer to the Getting Started or Technical Reference sections for details on accessing the
I401 i401 web page.
To reset the laser, you must lower the RH level below 95% and then cycle DC power off and back on. The
best method for lowering humidity is to connect a source of nitrogen or clean, dry air to the laser’s Gas
Purge port as described in the Getting Started section.
Important Note: Novanta highly recommends the use of purge gas to keep the internal humidity
level below 10%. See the Getting Started section for connection details and gas quality
specifications.
During laser operation, monitor information on the i401’s web page, including the Relative Humidity
value. When properly conditioned purge gas is flowing, the measured RH value should drop below 10%
within 10–15 minutes. If the relative humidity never drops below approximately 10%, then increase the gas
flow rate slightly. If the RH value exceeds 85% during operation, a warning is displayed in the web page’s
lower (yellow) error message section. If the RH value continues to rise and reaches 95%, lasing is halted,
and a fault is displayed in the upper (red) error message section of the web page.
Web interface
Symptom:
DC power is applied, but the I401 web interface cannot be accessed.
Possible Causes:
• The peer-to-peer connection was made using a straight-thru Ethernet cable.
Use an Ethernet crossover cable for a peer-to-peer connection between the i401 laser and the computer.
Use a straight-thru cable when connecting to a network using a network router, switch, or hub.
• The factory-default IP address was changed.
i401 lasers are pre-configured at the factory with a fixed IP address of 192.168.50.50. If this address was
changed in the field, then you must locate the new IP address, it cannot be remotely reset.
Symptom:
The I401 is connected to a network; however, the i401 web interface does not open or locks up while
receiving data from the laser.
Possible Causes:
• The i401 laser was connected to the network using a crossover cable.
