Laser troubleshooting
During normal operation or when laser faults occur, OEM v30 status LEDs and output signals annunciate laser status as previously
described in Tables 5-2–5-13. This section provides more detailed information for troubleshooting and resolving a variety of laser faults.
Each Symptom listed in this section describes a particular fault. For each Symptom, specific causes and solutions are described under
Possible Causes.
Symptom:
•
The following status LED and I/O states exist:
LASE LED – Off Lase Indicator – Low (0V Over-temp Fault – Low (0V)
Voltage Ok – High(+5V) RDY LED – Off Laser Ready – Low (0V)
DC Voltage Fault – Low (0V) PWR LED – Green
Temperature OK – High (+5V) Laser OK – Low (0V)
Possible Causes:
• The Laser Enable input is not active.
A +5 VDC Laser Enable signal must be applied between Pin 9, Laser Enable, and Pin 8, GND, on the DB-9
connector (or Pin 7, Laser Enable, and Pin 8, GND, on the RJ45 connector) to enable lasing.
In some cases, it is easier to troubleshoot the laser processing system by disconnecting field wiring from
the DB-9, or RJ45, connector and then installing the DB-9 Quick Start Plug to verify v30 laser operation.
If the laser was not shipped with a Quick Start Plug, you can fabricate one as shown in Figure below.
