Table 5-10 Laser fault codes

The Laser Ready output opens (switches to a high impedance state) when a fault occurs.

A continuously flashing SHT LED indicates a No-Strike condition, and the laser is limited to a
5% duty cycle (at 5 kHz). If the No-Strike condition clears, the laser will recover without
cycling power. Common causes of No-Strike condition (gas breakdown) issues are
environmental conditions—like cold overnight temperatures when the laser is off. In situations
like this, it may take 30 to 60 seconds for gas breakdown to occur and begin normal daily
operation. The Fault Detected output closes for a minimum of 50 ms or until the No-Strike
condition clears.
Web page fault annunciation
The i401 web interface displays errors and warnings in real-time on the home page in either the error
message area or the warning message area. Hard faults that require a DC power cycle are always shown
in the error message area. Operating data is not archived or displayed if the web interface is inactive
when the fault occurs. The event log page displays fault information recorded over the life of the laser.
See the i401 web interface section in the Technical Reference section for web page access details.
Resetting faults
Remote interlock condition
A remote interlock condition occurs when the Remote Interlock input opens (the INT LED changes from
green to red and the Interlock Open output Closes). The internal shutter mechanism closes (even when
the Shutter Open Request input is active) and lasing is halted immediately.
Warning: Serious Personal Injury
i401 OEM lasers, remote interlock faults are not latched. Clearing the fault condition re-
enables the RDY indicator and the laser will fire after the five second delay provided the SHT
indicator is lit and a PWM Command signal is applied. Because exposure to 10.6
µ
m CO2 laser
radiation can inflict severe corneal injuries and seriously burn human tissue, the OEM or
System Integrator must ensure that appropriate safeguards are in place to prevent
unintended lasing.
