Troubleshooting
General laser fault conditions
Each Symptom listed below describes a particular fault condition. For each Symptom, specific causes and
solutions are described in the Possible Causes section.
Warning
serious
personal
injury
On OEM p100 lasers, remote interlock faults as well as No-Strike,
Frequency Limit, and 100% Duty Cycle conditions are
not latched.
Clearing the fault or error condition re-enables the
RDY
LED and las-
ing will begin immediately provided the
SHT
LED is lit and a PWM
Command signal is applied. Because exposure to 10.6 µm CO
2
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.
Symptom:
■ A remote interlock condition is indicated by the following status LED and I/O states:
INT
LED –
Red
Interlock Open –
Closed
TMP
LED – Green Fault Detected – Open
RDY
LED –
Off
Laser Ready –
Open
SHT
LED – Blue Shutter Open – Closed
LASE
LED – Off Laser Active – Open
Possible Causes:
■ No voltage is applied to Pin 3, the Remote Interlock input, on the
User I/O
connector.
On systems using remote interlocks, check to see that a positive or negative voltage in the range of ±5–24
VDC is applied to Pin 3,
Remote Interlock , with respect to Pin 11, Input Common , on the
User I/O
con-
nector (refer to
User I/O connections
in the Technical Reference chapter for details). For systems not using
interlocks, connect the factory-supplied
Quick Start Plug
to the
User I/O
connector on the laser’s rear panel
or wire your male DB-15 connector so that Pin 11 ( Input Common ) is jumpered to Pin 12 ( Auxiliary DC
Power Ground ) and Pin 3 ( Remote Interlock ) is jumpered to Pin 4 (+5 VDC Auxiliary Power ).
Symptom:
■
An over-temperature fault is indicated by the following status LED and I/O states:
INT LED – Green Interlock Open – Open
TMP LED – Red Fault Detected – Closed
RDY LED – Off Laser Ready – Open
SHT LED – Blue Shutter Open – Closed
LASE LED – Off Laser Active – Open
Possible Causes:
■ Coolant temperature is above 30 °C (86 °F) or there is inadequate coolant flow through the laser.
Verify that the chiller is maintaining a water temperature between 18 °C–30 °C (64 °F–86 °F).
