Symptom:
•
A remote interlock fault is indicated:
INT LED – Red Interlock Open – Closed
TMP LED – Green Over Temperature – Open
RDY LED – Off Laser Ready – Open
SHT LED – Blue Shutter Open – Closed
LASE LED – Off Laser Active – Open
Possible Causes:
•
No voltage applied to Pin 3 (Remote Interlock) on the User I/O connector.
On systems using remote interlocks, check to see that a positive or negative voltage (±5–24 VDC) is ap-
plied to Pin 3, Remote Interlock, with respect to Pin 11, Input Common, on the User I/O connector (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:
INT LED – Green Interlock Open – Open
TMP LED – Red Over Temperature – Closed
RDY LED – Off Laser Ready – Open
SHT LED – Blue Shutter Open – Closed
LASE LED – Off Laser Active – Open
Possible Causes:
•
Water-cooled lasers – Cooling water temperature is above 22 °C (72 °F) or there is inadequate
water flow through the laser.
Check that your chiller is maintaining a water temperature between 18 °C–22 °C (64 °F–72 °F) at a flow
rate of one gallon per minute (GPM). If water temperature is OK, check the flow rate. The simplest way
Warning: Serious Personal Injury
On v40 OEM lasers, remote interlock (INT) faults are not latched. Clearing the fault condition re-
enables the RDY indicator and the laser will fire after the five-second delay provided that 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.
