Troubleshooting
On OEM lasers, remote interlock conditions are not latched. Re-establish the Remote Interlock signal
input (Remote Interlock LED changes from red to green) to enable the Ready indicator and begin lasing
after the ve-second delay.
Over temperature fault
Over temperature faults occur when thermal limits in the laser are exceeded (the Temp LED changes from
green to red).
To reset an over-temperature fault on Keyswitch-equipped lasers, lower coolant temperature below 24 °C
(f100/f200) or 28 °C (f201/f400), cycle DC power to the laser, and then cycle the Keyswitch from OFF/RE-
SET to ON (or apply a ±5–24 VDC Remote Reset/Start Request pulse with the Keyswitch set to ON).
When the Ready indicator illuminates, lasing is enabled after a ve-second delay.
Note: Because of the over-temperature latch circuit, the Temp indicator remains red prior to cycling
power even after the laser has cooled suciently to begin operation. If the Temp indicator remains
red after cycling power, the laser is not suciently cooled—cool the laser for several more min-
utes, cycle power, and then cycle the Keyswitch.
On OEM f100D/f200D and f201C/f400C lasers, over-temperature faults are now latched. To reset an
over-temperature fault, lower coolant temperature below 24 °C (f100/f200) or 28 °C (f201/f400) to cool
the laser and then cycle DC power to the laser. Once the Temp indicator is green and the Ready lamp is lit,
lasing is possible after the ve-second delay.
Shutter
A closed shutter (f100/f200 only) is not considered a fault condition. When the physical Shutter Switch is
opened and a Shutter Open Request signal is applied, lasing is enabled immediately after the ve-second
delay if the Ready indicator is illuminated yellow.
Under voltage fault
An under voltage fault occurs when the DC input voltage falls below preset limits. This fault is indicated
by the Ready LED ashing 1 blink. To reset an under voltage fault, rst correct the voltage problem and
ensure that 96 VDC is measured at the laser under full-load conditions. Next, cycle DC power o and then
on again. On Keyswitch-equipped lasers, you must also toggle the Keyswitch from OFF/RESET to ON (or
apply a ±5–24 VDC Remote Reset/Start Request pulse with the Keyswitch set to ON). When the Ready
LED illuminates, lasing is enabled after a ve-second delay.
Over voltage fault
An over voltage fault occurs when the DC input voltage rises above preset limits. This fault is indicated by
the Ready LED ashing 2 blinks. To reset an over voltage fault, rst correct the voltage problem and ensure
that 96 VDC is measured at the laser under full-load conditions. Next, cycle DC power o and then on
again. On Keyswitch-equipped lasers, you must also toggle the Keyswitch from OFF/RESET to ON (or apply
a ±5–24 VDC Remote Reset/Start Request pulse with the Keyswitch set to ON). When the Ready LED
illuminates, lasing is enabled after a ve-second delay.
